+ * The diagram above describes the PF/VF mailbox state machine.  There

+ * Closed: This state represents a mailbox that is in a standby state
+ *	   with interrupts disabled.  In this state the mailbox should not
+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the
+ *	    destination is received or when a data message is received with
+ *	    a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ *       entity and the remote.  It will fall back to connect in the event of
+ *       receiving either an error message, or a disconnect message.  It will
+ *       transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ *	       the connection.  It will do so at the first point where it knows
+ *	       that the remote endpoint is either done sending, or when the
+ *	       remote endpoint has fallen back into connect.

+ * The layout above describes the format for the header used in the PF/VF
+ * mailbox.  The header is broken out into the following fields:
+ * Type: There are 4 supported message types
+ *		0x8: Data header - used to transport message data
+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error
+ *		experienced.

[PATCH v2 00/15] lib/librte_pmd_fm10k : fm10k pmd driver

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The patch set add poll mode driver for the host interface of Intel
Red Rock Canyon silicon, which integrates NIC and switch functionalities.
The patch set include below features:

1. Basic RX/TX functions for PF/VF.
2. Interrupt handling mechanism for PF/VF.
3. per queue start/stop functions for PF/VF.
4. Mailbox handling between PF/VF and PF/Switch Manager.
5. Receive Side Scaling (RSS) for PF/VF.
6. Scatter receive function for PF/VF.
7. reta update/query for PF/VF.
8. VLAN filter set for PF.
9. Link status query for PF/VF.

Changes in v2:
- Merge 3 patches into 1 to configure fm10k compile environment.
- Rework on log code to follow style in ixgbe.
- Rework log message, remove redundant '\n'
- Update Copyright year from "2014" to "2015"
- Change base driver directory name from SHARED to base
- Add more description in log for patch "add PF and VF interrupt"
- Merge 2 patches into 1 to register fm10k driver
- Define macro to replace numeric for lower 32-bit mask.

+ * Closed: This state represents a mailbox that is in a standby state
+ *	   with interrupts disabled.  In this state the mailbox should not
+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the
+ *	    destination is received or when a data message is received with
+ *	    a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ *       entity and the remote.  It will fall back to connect in the event of
+ *       receiving either an error message, or a disconnect message.  It will
+ *       transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ *	       the connection.  It will do so at the first point where it knows
+ *	       that the remote endpoint is either done sending, or when the
+ *	       remote endpoint has fallen back into connect.

+ * Type: There are 4 supported message types
+ *		0x8: Data header - used to transport message data
+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error

[PATCH v3 00/15] lib/librte_pmd_fm10k : fm10k pmd driver

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The patch set add poll mode driver for the host interface of Intel
Red Rock Canyon silicon, which integrates NIC and switch functionalities.
The patch set include below features:

1. Basic RX/TX functions for PF/VF.
2. Interrupt handling mechanism for PF/VF.
3. per queue start/stop functions for PF/VF.
4. Mailbox handling between PF/VF and PF/Switch Manager.
5. Receive Side Scaling (RSS) for PF/VF.
6. Scatter receive function for PF/VF.
7. reta update/query for PF/VF.
8. VLAN filter set for PF.
9. Link status query for PF/VF.

Changes in v3:
- Update base driver.
- Define several macros to pass base driver compile.

Changes in v2:
- Merge 3 patches into 1 to configure fm10k compile environment.
- Rework on log code to follow style in ixgbe.
- Rework log message, remove redundant '\n'
- Update Copyright year from "2014" to "2015"
- Change base driver directory name from SHARED to base
- Add more description in log for patch "add PF and VF interrupt"
- Merge 2 patches into 1 to register fm10k driver
- Define macro to replace numeric for lower 32-bit mask.

+ * Closed: This state represents a mailbox that is in a standby state

+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the
+ *	    destination is received or when a data message is received with
+ *	    a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ *       entity and the remote.  It will fall back to connect in the event of
+ *       receiving either an error message, or a disconnect message.  It will
+ *       transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ *	       the connection.  It will do so at the first point where it knows
+ *	       that the remote endpoint is either done sending, or when the
+ *	       remote endpoint has fallen back into connect.

+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error

[PATCH v4 00/15] lib/librte_pmd_fm10k : fm10k pmd driver

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The patch set add poll mode driver for the host interface of Intel
fm10k series of silicons, which integrate NIC and switch 
functionalities. The patch set include below features:

1. Basic RX/TX functions for PF/VF.
2. Interrupt handling mechanism for PF/VF.
3. per queue start/stop functions for PF/VF.
4. Mailbox handling between PF/VF and PF/Switch Manager.
5. Receive Side Scaling (RSS) for PF/VF.
6. Scatter receive function for PF/VF.
7. reta update/query for PF/VF.
8. VLAN filter set for PF.
9. Link status query for PF/VF.

Change in v4:
- Change commit log to remove improper words.

Changes in v3:
- Update base driver.
- Define several macros to pass base driver compile.

Changes in v2:
- Merge 3 patches into 1 to configure fm10k compile environment.
- Rework on log code to follow style in ixgbe.
- Rework log message, remove redundant '\n'
- Update Copyright year from "2014" to "2015"
- Change base driver directory name from SHARED to base
- Add more description in log for patch "add PF and VF interrupt"
- Merge 2 patches into 1 to register fm10k driver
- Define macro to replace numeric for lower 32-bit mask.

+ * Closed: This state represents a mailbox that is in a standby state
+ *	   with interrupts disabled.  In this state the mailbox should not
+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the
+ *	    destination is received or when a data message is received with
+ *	    a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ *       entity and the remote.  It will fall back to connect in the event of
+ *       receiving either an error message, or a disconnect message.  It will
+ *       transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ *	       the connection.  It will do so at the first point where it knows
+ *	       that the remote endpoint is either done sending, or when the
+ *	       remote endpoint has fallen back into connect.

+ * The layout above describes the format for the header used in the PF/VF

+ * Type: There are 4 supported message types
+ *		0x8: Data header - used to transport message data
+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error

[PATCH v5 00/17] lib/librte_pmd_fm10k : fm10k pmd driver

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The patch set add poll mode driver for the host interface of Intel
Ethernet Switch FM10000 Series of silicons, which integrate NIC and
switch functionalities. The patch set include below features:

1. Basic RX/TX functions for PF/VF.
2. Interrupt handling mechanism for PF/VF.
3. per queue start/stop functions for PF/VF.
4. Mailbox handling between PF/VF and PF/Switch Manager.
5. Receive Side Scaling (RSS) for PF/VF.
6. Scatter receive function for PF/VF.
7. reta update/query for PF/VF.
8. VLAN filter set for PF.
9. Link status query for PF/VF.

Change in v5:
- Add sanity check for mbuf allocation.
- Add a new patch to claim fm10k driver review
- Change commit log.
- Add unlikely in func rx_desc_to_ol_flags to gain performance
- Add a new patch to add ABI version

Change in v4:
- Change commit log to remove improper words.

Changes in v3:
- Update base driver.
- Define several macros to pass base driver compile.

Changes in v2:
- Merge 3 patches into 1 to configure fm10k compile environment.
- Rework on log code to follow style in ixgbe.
- Rework log message, remove redundant '\n'
- Update Copyright year from "2014" to "2015"
- Change base driver directory name from SHARED to base
- Add more description in log for patch "add PF and VF interrupt"
- Merge 2 patches into 1 to register fm10k driver
- Define macro to replace numeric for lower 32-bit mask.

[PATCH v5 01/17] fm10k: add base driver

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Base driver is developed and maintained by Intel ND team, includes
basic functional service to Intel Ethernet Switch FM10000 Series
of silicons.
Any suggestion on bug fix and improvement within this directory is
welcome, but need this team to change and update.

+ *	   this state is for the system to make the connect() call for the

+ * The layout above describes the format for the header used in the PF/VF
+ * mailbox.  The header is broken out into the following fields:
+ * Type: There are 4 supported message types
+ *		0x8: Data header - used to transport message data
+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error
+ *		experienced.

[PATCH v6 00/16] lib/librte_pmd_fm10k : fm10k pmd driver

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The patch set add poll mode driver for the host interface of Intel
Ethernet Switch FM10000 Series of silicons, which integrate NIC and
switch functionalities. The patch set include below features:

1. Basic RX/TX functions for PF/VF.
2. Interrupt handling mechanism for PF/VF.
3. per queue start/stop functions for PF/VF.
4. Mailbox handling between PF/VF and PF/Switch Manager.
5. Receive Side Scaling (RSS) for PF/VF.
6. Scatter receive function for PF/VF.
7. reta update/query for PF/VF.
8. VLAN filter set for PF.
9. Link status query for PF/VF.

Change in v6:
- Merge ABI patch with fm10k driver regsiter patch.
- Fix typo.
- Rework comments.
- Minor adjustment on commit log.
- Increase error variable after mbuf allocation failed.

Change in v5:
- Add sanity check for mbuf allocation.
- Add a new patch to claim fm10k driver review
- Change commit log.
- Add unlikely in func rx_desc_to_ol_flags to gain performance
- Add a new patch to add ABI version

Change in v4:
- Change commit log to remove improper words.

Changes in v3:
- Update base driver.
- Define several macros to pass base driver compile.

Changes in v2:
- Merge 3 patches into 1 to configure fm10k compile environment.
- Rework on log code to follow style in ixgbe.
- Rework log message, remove redundant '\n'
- Update Copyright year from "2014" to "2015"
- Change base driver directory name from SHARED to base
- Add more description in log for patch "add PF and VF interrupt"
- Merge 2 patches into 1 to register fm10k driver
- Define macro to replace numeric for lower 32-bit mask.

+ * Closed: This state represents a mailbox that is in a standby state

+ *	   read the mailbox or write any data.  The only means of exiting
+ *	   this state is for the system to make the connect() call for the
+ *	   mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection.  It will
+ *	    post a connect message with no specified destination and will
+ *	    wait for a reply from the other side of the mailbox.  This state
+ *	    is exited when either a connect with the local mailbox as the
+ *	    destination is received or when a data message is received with
+ *	    a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ *       entity and the remote.  It will fall back to connect in the event of
+ *       receiving either an error message, or a disconnect message.  It will
+ *       transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ *	       the connection.  It will do so at the first point where it knows
+ *	       that the remote endpoint is either done sending, or when the
+ *	       remote endpoint has fallen back into connect.

+ *		0xC: Connect header - used to establish connection
+ *		0xD: Disconnect header - used to tear down a connection
+ *		0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ *		Tail index actually consists of two parts.  The MSB of
+ *		the head is a loop tracker, it is 0 on an even numbered
+ *		loop through the FIFO, and 1 on the odd numbered loops.
+ *		To get the actual mailbox offset based on the tail it
+ *		is necessary to add bit 3 to bit 0 and clear bit 3.  This
+ *		gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ *		Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ *		The maximum message size is provided during connect to avoid
+ *		jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ *		The error number provides a indication of the type of error

[PATCH v6 04/16] config: change config files to add fm10k into compile

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Change config/common_bsdapp and config/common_linuxapp, add
   macros to control fm10k pmd driver compile for linux and bsd.
2. Change lib/Makefile to add fm10k driver into compile list.
3. Change mk/rte.app.mk to add fm10k lib into link.

Signed-off-by: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

[PATCH v6 08/16] fm10k: add Rx/Tx single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

[PATCH v6 10/16] fm10k: add receive and tranmit function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add fm10k_recv_pkts and fm10k_xmit_pkts functions.
2. Link app function pointer to actual fm10k recv/xmit
   functions.
3. Change Makefile to compile new file fm10k_rxtx.c

[PATCH v6 14/16] fm10k: add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add functions to enable PF/VF interrupt.
2. Add function to process error message passed from interrupt.
2. Add 2 interrupt handling functions, one for PF and one for VF.
2. Enable interrupt after completing initialization of NIC.

[PATCH v5 08/17] fm10k: add RX/TX single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

Same comment as before, do not directly use RTE_LOG.
This is init stuff, you have a PMD_INIT_LOG macro.

By the way, I need to dig deeper into this, but I can see multiple patches
ensuring buffer alignment.
Do we really need to validate this alignment here, if we already validated
this constraint at the mempool level ?

Agreed, the comment should be fixed.

This is really a sanity check. The buffer alignment needs to be
checked at runtime becuase a user could modify the alignment. We
provide a check here to be extra safe, and hopefully to fail at
init time rather than later.

There are two ways to satisfy the alignment requirements for the
hardware. Currently the driver implements the 512B alignment, but
it is possible somebody may want to the other 8B alignment w/o
crossing a 4K page boundary.  This sanity check would help catch
any possible issues in the future related to buffer alignment.

[PATCH v5 14/17] fm10k: Add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.

[PATCH v4 08/15] fm10k: add RX/TX single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

[PATCH v4 10/15] fm10k: add receive and tranmit function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add fm10k_recv_pkts and fm10k_xmit_pkts functions.
2. Link app function pointer to actual fm10k recv/xmit
   functions.
3. Change Makefile to compile new file fm10k_rxtx.c

Same thing here.  The return value should be checked in case the

[PATCH v4 14/15] fm10k: Add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.

[PATCH v3 08/15] fm10k: add RX/TX single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Configure RSS in fm10k_dev_rx_init function.
2. Add fm10k_rss_hash_update and fm10k_rss_hash_conf_get to get
   and inquery RSS configuration.

[PATCH v3 14/15] fm10k: Add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.

[PATCH v2 04/15] Change config files to add fm10k into compile

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Change config/common_bsdapp and config/common_linuxapp, add
   macros to control fm10k pmd driver compile for linux and bsd.
2. Change lib/Makefile to add fm10k driver into compile list.
3. Change mk/rte.app.mk to add fm10k lib into link.

Signed-off-by: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

[PATCH v2 08/15] fm10k: add RX/TX single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

[PATCH v2 10/15] fm10k: add receive and tranmit function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add fm10k_recv_pkts and fm10k_xmit_pkts functions.
2. Link app function pointer to actual fm10k recv/xmit
   functions.
3. Change Makefile to compile new file fm10k_rxtx.c

[PATCH v2 14/15] fm10k: Add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.

The 2 ".c" files are empty while the 2 ".h" files include code. "Makefile" includes rules to
compile the ".c" files, I don't like to break the compile for every single patch, that's why
the 2 ".c" files are added in this patch.

That doesn't really answer the question.  Theres no need to add empty files
here.  Just add the headers alone and add the empy files on the first commit
where you have code to put in them.  Adjust the makefile so that you add them
into the compilation in the same commit that you populate the file to avoid a
FTBFS error.

This comment applies to the logs macro (and the rest of the patchset).
- don't use a build option for logs to be displayed, especially if these
are init messages or error messages that prevent the pmd from working
- you can remove this "Use RTE_LOG directly to make sure this error is
seen." in fm10k_rx_queue_setup if you use a "init" macro that is not under
a build option
- don't use \n in logs, only one is enough

Please, check the cleanup work that has been done in other Intel pmd (for
example, ixgbe).

I would really prefer we have consistent logs across dpdk.

Re: [PATCH 03/18] fm10k: Add empty fm10k files

Subject: Re: [dpdk-dev] [PATCH 03/18] fm10k: Add empty fm10k files

From: Jeff Shaw <jeffrey.b.shaw@intel.com>

Define macros and basic data structure.
Define rte_log wrapper functions.

This comment applies to the logs macro (and the rest of the patchset).
- don't use a build option for logs to be displayed, especially if these are init messages or error messages that prevent the pmd from working
- you can remove this "Use RTE_LOG directly to make sure this error is seen." in fm10k_rx_queue_setup if you use a "init" macro that is not under a build option
- don't use \n in logs, only one is enough

Please, check the cleanup work that has been done in other Intel pmd (for example, ixgbe).

I would really prefer we have consistent logs across dpdk.

[Mark] Thanks for your comments. I'll check it.

I know this isn't the job of this patch series, but I don't really understand
why we bother with this pattern for filling out pci id tables.  A PMD supports
specific hardware, we might as well use the generic RTE_PCI_DEVICE macro in the
driver rather than creating a FM10K specific wrapper, only to have to do some
ifdef trickery in the rte_cpi_dev_ids file and some include magic to fill it
out.

I'd suggest that you just use RTE_PCI_DEVICE macro here, and make your own table
(keep the specific device id values in the common file.  Then we can clean out
the macro maggic in a later update.

If we are going that way, my only concern is that this makes it hard to
"discover" the pci devices that need to be bound to igb_uio/vfio/whatever
kernel driver, and so we must rely either on a global list (like this
rte_pci_dev_ids.h) or on scripts with hardcoded pci device ids in them ...

In the end, we miss something to have dpdk work automatically like it used
to be, before the pci devices ids were stripped out of igb_uio.

I can see two solutions :
- all pmds export the pci device ids they support (this sounds like
modalias :-)) or they register into the eal that exports this information
for use by application, but to me the application should not bother with
this ...
- the pmd handles this automatically (like binding/unbinding on a kernel
driver), with a _runtime_ option to enable this behavior (default being "no
automatic bind")

Comments ? Ideas ?

I like the modalias idea, as it transports a table for uio/vfio to identify with
the binary that needs it, preventing a possible discrepancy in what the core
dpdk library identifies as supported devices and what the pmd DSO's actually do
support.

To implement it we would either provide our own linker script or have to do some
other make trickery.  The linker script is a bit more labor intensive, but might
provide some future benefit (if you see a need for non-standard sections that
you would like to suck into a given DSO in the future).  Make trickery would be
more straightforward, but requires that we add some additional make targets to
build out the dynamic table to be readable by outside utilities.  Maybe we could
use objcopy to add in a separate section after the dso link.  Not sure yet

Yes, but if a pmd can do this itself alone, there is no discrepancy either.

Thinking aloud ...
As long as the pmd does all the magic bindings, the dpdk core does not need
to know about it.
And if the dpdk core really needs to know about this (I can see no use case
here, just want to avoid being blocked later) a dynamic register system
would be fine too.

Not sure either, I just think we may reinvent the wheel :-)

Yes, absolutely, but it needs to be done in a way that an external binary can
inspect the object independently of its being loaded, and preferably in a
non-programatic context (since the uio bind/unbind utilities are separate
scripts).

The modinfo method involves putting info into a special data section that gets
processed as part of the kernel modpost build stage.  There, the additional
section gets translated into a C file, and built into its own object thats
attached to the final binary module.  We can so the same thing here if you like

We could do something simpler, too.  For instance we could add a field to the
struct that gets registered as part of the RTE_REGISTER_PMD macro, and export it
via a new ethdev library call.  That would be very straightforward, but the
implication there is that you would need a programatic method to interrogate
that information (a binary to call into the dpdk), which is not part of how the
bind/unbind scripts work today.

Yes, I'm not suggesting anything other than the pmd be responsible for codifying
its binding information.  Its how that information is exported to other
utilities that potentially increases the complexity of this operation.

Sure, I don't see a problem with that. If we properly macro-wrap this, we can
likely add a dynamic registration mechanism without having to change the pmds
later

Did you work on this ?


I have been playing with this, I will most likely propose patches soon.

My preferred approach is to dedicate an elf section for this ("à la" kernel
.modinfo).
I tried to reuse modinfo, but the problem is that kmod implementation is
checking the filename extension against .ko and .ko.gz.

I find it a bit too bad to have to rewrite this kind of tool just for dpdk
... but on the other hand we would need something for bsd as well or we
give a shell script that rely on readelf to retrieve theis section.

Yes, this makes sense.

Well, you can alter modinfo so that it looks at .so files if you like, but thats
not the only tool you can use.  Truthfully you can just use objdump if you

See above, try objdump -j=.modinfo -S /path/to/kernel/module.  objdump doesn't
care about file extensions, as long as its ELF.  With that you can:

1) Dump out any section contents you like
2) strip away the application top end, and just use libbfd to get at the elf
contents if you like.

Yes, I reached the same conclusion.
Ok, I will see what I can do.

I partially agree with you. Maybe a better solution is to use the mechanism that applied
in kernel to register PCI driver. Driver maintains a device list that it can manage and provide
a hook function to detect if new device can be managed by the driver.  Then, DPDK core
library needn't worry about the long device list (Maybe script that unbind/bind device needs 
such info, it's another story). 

But I'd like to keep current implementation unchanged since final decision is not made yet. If
new mechanism is introduced, I would like to update to adapt to the new changes.

[PATCH 09/18] fm10k: add RX/TX single queue start/stop function

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
   1. Address is 512B aligned
   2. Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

[PATCH 12/18] fm10k: add PF RSS support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

1. Configure RSS in fm10k_dev_rx_init function.
2. Add fm10k_rss_hash_update and fm10k_rss_hash_conf_get to get
   and inquery RSS configuration.

Its not really random if its statically allocated and assigned.  The kernel has
started randomizing these default keys, it seems like a sensible thing to do
here as well, as this is the init path and not performance sensitive

[PATCH 15/18] fm10k: Add SRIOV-VF support

[Chen Jing D(Mark)]

From: Jeff Shaw <jeffrey.b.shaw-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translatethe request to correct units.

For some functionalities that is unique to PF, driver will check
current driver type and behave correctly.

My rationale is to make every single patch not to break the compile. So, I'd like to
add the binary library into compile and link in last 2 patches, after all the actual code
are patched.  For Patch 2, I think you are right, maybe a better way is to move it as 
patch "16". 

But I'm not sure whether I should merge these 3 together. You know, somebody may
not happy to see the changes in different directory to appear in single patch.

No, I think you are wrong. You can have modifications in different directories
in a patch. A patch must be atomic (one addition/change/feature at a time) and
buildable. In your case, it would be best to have a patch allowing compilation
of fm10k after the patch for "register". So it would mean we are able to test
the minimal driver and each feature added after.

Thanks

As Thomas notes, its fine to change multiple directories, its the functionality
add and ability to compile that needs to be atomic to a commit.

Why is there a SHARED directory in the driver?  Are there other drivers that use
the shared fm10k code?

No, the other poll-mode drivers do not use the shared fm10k code. The
directory is similar to the 'ixgbe' and 'i40e' directories in their
respective PMDs, only that it is named 'SHARED' for the fm10k driver.

So shared is a bad name in the context of DPDK.
Inside Intel, it can be understood that you share it between projects,
but in DPDK, it's only a base driver.

OK, I'll change "SHARED" to "fm10k".

I think that "base" would be more appropriate:
fm10K/base instead of fm10k/fm10k.
