[PATCH 01/16] fm10k/base: cleanup namespace pollution and correct typecast

[Wang Xiao W]

Correct typecast in fm10k_update_xc_addr_pf.

Make functions that are only referenced locally static.

And fix the function header comment for fm10k_tlv_attr_nest_stop() while
we're at it.

Wrap fm10k_msg_data fm10k_iov_msg_data_pf[] in the new ifndef
NO_DEFAULT_SRIOV_MSG_HANDLERS so that drivers with custom SR-IOV
message handlers can strip it.

remove unused struct element in struct fm10k_mac_ops.

[PATCH 02/16] fm10k/base: use bitshift for itr_scale

[Wang Xiao W]

Upstream community wishes us to use bitshift instead of a divisor,
because this is faster, and prevents any need for a '0' check. In our
case, this even works out because default Gen3 will be 0.

Because of this, we are also able to remove the check for non-zero value
in the vf code path since that will already be the default Gen3 case.

[PATCH 03/16] fm10k/base: reset max_queues on init_hw_vf failure

[Wang Xiao W]

VF drivers must detect how many queues are available. Previously, the
driver assumed that each VF has at minimum 1 queue. This assumption is
incorrect, since it is possible that the PF has not yet assigned the
queues to the VF by the time the VF checks. To resolve this, we added a
check first to ensure that the first queue is infact owned by the VF at
init_hw_vf time. However, the code flow did not reset hw->mac.max_queues
to 0. In some cases, such as during reinit flows, we call init_hw_vf
without clearing the previous value of hw->mac.max_queues. Due to this,
when init_hw_vf errors out, if its error code is not properly handled
the VF driver may still believe it has queues which no longer belong to
it. Fix this by clearing the hw->mac.max_queues on exit due to errors.

[PATCH 04/16] fm10k/base: document ITR scale workaround in VF TDLEN register

[Wang Xiao W]

Add comments which properly explain the undocumented use of bits in
TDLEN register prior to VF initializing it to the correct value. Note
that the mechanism is entirely software-defined and explain its purpose
to help reduce confusion in the future.

[PATCH 06/16] fm10k/base: use BIT macro instead of open-coded bit-shifting of 1

[Wang Xiao W]

The upstream Linux kernel community prefers using the BIT macro over
bit-shifting a 1.  Similar to how this is handled in the i40e shared code,
define a macro for OSes that do not already have it and wrap all that in
LINUX_MACROS so that it can be stripped from the Linux driver.

The upstream Linux kernel community prefers avoiding CamelCase in
variables, function names, etc.

[PATCH 09/16] fm10k/base: allow removal of is_slot_appropriate function

[Wang Xiao W]

The Linux Kernel provides the OS a call "pcie_get_minimum_link" which
can crawl the PCIe tree and determine the actual minimum link speed of a
device which is a more general check than provided by
is_slot_appropriate. Thus, the upstream driver does not use or want the
is_slot_appropriate function call. Add a NO_IS_SLOT_APPROPRIATE_CHECK
definition which can be defined during strip process to remove the code.
If left undefined (the default) then the code will all be active and no
driver changes should be necessary.

[PATCH 10/16] fm10k/base: consistently use VLAN ID when referencing vid variables

[Wang Xiao W]

The vid variable name is shorthand for VLAN ID, so we should use this in
comments explaining what is happening.

[PATCH 11/16] fm10k/base: fix comment per upstream review changes

[Wang Xiao W]

The comment here was changed during review of upstream patch, and the
new wording is slightly more clear. Re-write the comment in SHARED code
based on this new wording.

Fix a number of mailbox comment issues with function header comments,
lower-case acronyms (i.e. FIFO, TLV), incorrect function names in DEBUGFUNC(),
duplicate comments and a stubbed-out header comment for fm10k_sm_mbx_init.

[PATCH 12/16] fm10k/base: TLV structures must be 4byte aligned, not 1byte aligned

[Wang Xiao W]

Per comments from an upstream patch, and looking at how TLV LE_STRUCT
code works, we actually want these structures to be 4byte aligned, not
1byte aligned. In practice, 1byte alignment has worked so far because
all our structures end up being a multiple of 4. But if a future TLV
structure were added that had a u8 or similar sticking on the end things
would break. Fix this by using 4byte alignment which will prevent the
TLV LE_STRUCT code from breaking. Update the comment explaining that we
need 4byte alignment of our structures.

[PATCH 15/16] fm10k: use default mailbox message handler for pf

[Wang Xiao W]

The new share code makes fm10k_msg_update_pvid_pf function static, so we can
not refer to it now in fm10k_ethdev.c. The registered pf handler is almost the
same as the default pf handler, removing it has no impact on mailbox.

[PATCH 16/16] fm10k/base: add macro definitions that are needed

[Wang Xiao W]

Some macros such as FM10K_RXINT_TIMER_SHIFT are removed in the share
code drop, but they are needed in dpdk/fm10k. This patch put all these
necessary macros into fm10k_osdep.h

What patch makes the function static, as we need to ensure that the build is
not broken by having this patch in the wrong place in the patchset?

Also, it seems strange having this patch in the middle of a series of base code
updates - perhaps it should go first, so that all base code update patches can
go one after the other.

It's the first patch in the patch set that makes the function static.

The 0015.patch and 0016.patch are two extra fix patches made by myself. The 0015 is for the
"static fm10k_msg_update_pvid_pf " issue, the 0016 adds back a few macro definitions
which are removed in shared code but are needed in dpdk/fm10k, I add these necessary
macros into fm10k/base/fm10k_osdep.h which is controlled by dpdk driver.

I put the two extra (15/16, 16/16) fix patches last, (15/16) is a change for fm10k_ethdev.c,
so I prefix the subject with "fm10k: ", (16/16) is a change for base/fm10k_osdep.h, so I prefix
the subject with "fm10k/base: ".

Wang, Xiao

So does this patch not need to go before patch 1, if we can't refer to the function
once patch one is applied?

[PATCH v2 01/16] fm10k: use default mailbox message handler for pf

[Wang Xiao W]

The new share code makes fm10k_msg_update_pvid_pf function static, so we can
not refer to it now in fm10k_ethdev.c. The registered pf handler is almost the
same as the default pf handler, removing it has no impact on mailbox.

[PATCH v2 02/16] fm10k/base: add macro definitions that are needed

[Wang Xiao W]

Some macros such as FM10K_RXINT_TIMER_SHIFT are removed in the share
code drop, but they are needed in dpdk/fm10k. This patch put all these
necessary macros into fm10k_osdep.h

[PATCH v2 03/16] fm10k/base: cleanup namespace pollution and correct typecast

[Wang Xiao W]

Correct typecast in fm10k_update_xc_addr_pf.

Make functions that are only referenced locally static.

And fix the function header comment for fm10k_tlv_attr_nest_stop() while
we're at it.

Wrap fm10k_msg_data fm10k_iov_msg_data_pf[] in the new ifndef
NO_DEFAULT_SRIOV_MSG_HANDLERS so that drivers with custom SR-IOV
message handlers can strip it.

remove unused struct element in struct fm10k_mac_ops.

[PATCH v2 04/16] fm10k/base: use bitshift for itr_scale

[Wang Xiao W]

Upstream community wishes us to use bitshift instead of a divisor,
because this is faster, and prevents any need for a '0' check. In our
case, this even works out because default Gen3 will be 0.

Because of this, we are also able to remove the check for non-zero value
in the vf code path since that will already be the default Gen3 case.

[PATCH v2 05/16] fm10k/base: reset max_queues on init_hw_vf failure

[Wang Xiao W]

VF drivers must detect how many queues are available. Previously, the
driver assumed that each VF has at minimum 1 queue. This assumption is
incorrect, since it is possible that the PF has not yet assigned the
queues to the VF by the time the VF checks. To resolve this, we added a
check first to ensure that the first queue is infact owned by the VF at
init_hw_vf time. However, the code flow did not reset hw->mac.max_queues
to 0. In some cases, such as during reinit flows, we call init_hw_vf
without clearing the previous value of hw->mac.max_queues. Due to this,
when init_hw_vf errors out, if its error code is not properly handled
the VF driver may still believe it has queues which no longer belong to
it. Fix this by clearing the hw->mac.max_queues on exit due to errors.

[PATCH v2 08/16] fm10k/base: use BIT macro instead of open-coded bit-shifting of 1

[Wang Xiao W]

The upstream Linux kernel community prefers using the BIT macro over
bit-shifting a 1.  Similar to how this is handled in the i40e shared code,
define a macro for OSes that do not already have it and wrap all that in
LINUX_MACROS so that it can be stripped from the Linux driver.

The upstream Linux kernel community prefers avoiding CamelCase in
variables, function names, etc.

[PATCH v2 11/16] fm10k/base: allow removal of is_slot_appropriate function

[Wang Xiao W]

The Linux Kernel provides the OS a call "pcie_get_minimum_link" which
can crawl the PCIe tree and determine the actual minimum link speed of a
device which is a more general check than provided by
is_slot_appropriate. Thus, the upstream driver does not use or want the
is_slot_appropriate function call. Add a NO_IS_SLOT_APPROPRIATE_CHECK
definition which can be defined during strip process to remove the code.
If left undefined (the default) then the code will all be active and no
driver changes should be necessary.

[PATCH v2 13/16] fm10k/base: fix comment per upstream review changes

[Wang Xiao W]

The comment here was changed during review of upstream patch, and the
new wording is slightly more clear. Re-write the comment in SHARED code
based on this new wording.

Fix a number of mailbox comment issues with function header comments,
lower-case acronyms (i.e. FIFO, TLV), incorrect function names in DEBUGFUNC(),
duplicate comments and a stubbed-out header comment for fm10k_sm_mbx_init.

[PATCH v2 14/16] fm10k/base: TLV structures must be 4byte aligned, not 1byte aligned

[Wang Xiao W]

Per comments from an upstream patch, and looking at how TLV LE_STRUCT
code works, we actually want these structures to be 4byte aligned, not
1byte aligned. In practice, 1byte alignment has worked so far because
all our structures end up being a multiple of 4. But if a future TLV
structure were added that had a u8 or similar sticking on the end things
would break. Fix this by using 4byte alignment which will prevent the
TLV LE_STRUCT code from breaking. Update the comment explaining that we
need 4byte alignment of our structures.

While the patch itself looks ok, checkpatch gives a warning about the commit
message being too long.

  maximum 75 chars per line)

Since the next patch breaks compilation, a V3 will be needed, so please fix this
warning in the process. I'd also ask that you run checkpatch on all patches
before submitting and fix any issue raised.

Compilation fails with this patch applied. Each patch of the set must leave the
repository in a compilable state. Please do a V3 patchset to fix.

>From the commit message it appears that a lot of things are being crammed into
one patch. Please consider splitting it up, so that each commit just looks at
doing one thing. If there are multiple one-line fixes, it's ok to put them into
a single patch with a generic title like "misc small fixes", but for multi-line
changes, it's best to have one change/fix per patch.

Note also, that for commits fixing problems, a "fixes" line should be included in
the commit message as documented here:

Thanks for the comment, I used an old checkpatch.pl to check the patches, it gave
no warning. I have updated the checkpatch.pl and got the above warning.
I will rework the patch set, thanks again.

[PATCH v3 00/18] fm10k: update shared code

[Wang Xiao W]

v3:
* Fixed checkpatch.pl warning about long commit message.
* Fixed the issue of compile failure about part of patches applied.
* Split the misc-small-fixes patch into several patches.

v2:
* Put the two extra fix patches ahead of the base code patches.

This patch set has passed regression test.

[PATCH v3 01/18] fm10k: use default mailbox message handler for PF

[Wang Xiao W]

The new share code makes fm10k_msg_update_pvid_pf function static, so we
can not refer to it now in fm10k_ethdev.c. The registered PF handler is
almost the same as the default PF handler, removing it has no impact on
mailbox.

[PATCH v3 02/18] fm10k/base: correct typecast in fm10k_update_xc_addr_pf

Since the resultant data type of the mac_update.mac_upper field is u16,
it does not make sense to typecast u8 variables to u32 first.

Make functions that are only referenced locally static.

Wrap fm10k_msg_data fm10k_iov_msg_data_pf[] in the new ifndef
NO_DEFAULT_SRIOV_MSG_HANDLERS so that drivers with custom SR-IOV
message handlers can strip it.

[PATCH v3 04/18] fm10k/base: use bitshift for itr_scale

[Wang Xiao W]

Upstream community wishes us to use bitshift instead of a divisor,
because this is faster, and prevents any need for a '0' check. In our
case, this even works out because default Gen3 will be 0.

Because of this, we are also able to remove the check for non-zero value
in the VF code path since that will already be the default Gen3 case.

[PATCH v3 05/18] fm10k/base: reset max_queues on init_hw_vf failure

[Wang Xiao W]

VF drivers must detect how many queues are available. Previously, the
driver assumed that each VF has at minimum 1 queue. This assumption is
incorrect, since it is possible that the PF has not yet assigned the
queues to the VF by the time the VF checks. To resolve this, we added a
check first to ensure that the first queue is infact owned by the VF at
init_hw_vf time. However, the code flow did not reset hw->mac.max_queues
to 0. In some cases, such as during reinit flows, we call init_hw_vf
without clearing the previous value of hw->mac.max_queues. Due to this,
when init_hw_vf errors out, if its error code is not properly handled
the VF driver may still believe it has queues which no longer belong to
it. Fix this by clearing the hw->mac.max_queues on exit due to errors.

Fixes: 20dc3445d100 ("fm10k: do not assume VF always has 1 queue")

[PATCH v3 09/18] fm10k/base: use BIT macro instead of open-coded bit-shifting of 1

The upstream Linux kernel community prefers using the BIT macro over
bit-shifting a 1.  Similar to how this is handled in the i40e shared code,
define a macro for OSes that do not already have it and wrap all that in
LINUX_MACROS so that it can be stripped from the Linux driver.

[PATCH v3 12/18] fm10k/base: allow removal of is_slot_appropriate function

[Wang Xiao W]

The Linux Kernel provides the OS a call "pcie_get_minimum_link" which
can crawl the PCIe tree and determine the actual minimum link speed of a
device which is a more general check than provided by
is_slot_appropriate. Thus, the upstream driver does not use or want the
is_slot_appropriate function call. Add a NO_IS_SLOT_APPROPRIATE_CHECK
definition which can be defined during strip process to remove the code.
If left undefined (the default) then the code will all be active and no
driver changes should be necessary.

[PATCH v3 14/18] fm10k/base: imporve comment per upstream review changes

[Wang Xiao W]

The comment here was changed during review of upstream patch, and the
new wording is slightly more clear. Re-write the comment in SHARED code
based on this new wording.

Fix a number of mailbox comment issues with function header comments,
lower-case acronyms (i.e. FIFO, TLV), incorrect function names in
DEBUGFUNC(), duplicate comments and a stubbed-out header comment for
fm10k_sm_mbx_init.

[PATCH v3 15/18] fm10k/base: fix TLV structures alignment

[Wang Xiao W]

Per comments from an upstream patch, and looking at how TLV LE_STRUCT
code works, we actually want these structures to be 4byte aligned, not
1byte aligned. In practice, 1byte alignment has worked so far because
all our structures end up being a multiple of 4. But if a future TLV
structure were added that had a u8 or similar sticking on the end things
would break. Fix this by using 4byte alignment which will prevent the
TLV LE_STRUCT code from breaking. Update the comment explaining that we
need 4byte alignment of our structures.

Fixes: e24fed68236a ("fm10k: pack TLV overlay structures correctly")

[PATCH v3 17/18] fm10k/base: minor cleanups

[Wang Xiao W]

Some cleanups to better reflect the code that was actually pushed out to
the upstream Linux community.

Among the above cleanups, a few macros such as FM10K_RXINT_TIMER_SHIFT are
removed, but they are needed in dpdk/fm10k, so we have to put all these
necessary macros into fm10k_osdep.h.

An earlier ack should be reflected by putting the ack on all patches of the set
in later revisions. If it's only on patch 1, that implies that only that one patch
has been acked. If the ack is included in the cover letter only, then it's likely
to be missed, as a series ack is expected as a reply to the cover letter (because
as stated above, subsequent revs should include the ack in each patch itself)
