[Patch net-next v1 00/12] net: dsa: microchip: add PTP support for KSZ9563/KSZ8563 and LAN937x

[Patch net-next v1 00/12] net: dsa: microchip: add PTP support for KSZ9563/KSZ8563 and LAN937x

[Arun Ramadoss]

KSZ9563/KSZ8563 and  LAN937x switch are capable for supporting IEEE 1588 PTP
protocol.  LAN937x has the same PTP register set similar to KSZ9563, hence the
implementation has been made common for the KSZ switches.  KSZ9563 does not
support two step timestamping but LAN937x supports both.  Tested the 1step &
2step p2p timestamping in LAN937x and p2p1step timestamping in KSZ9563.

This patch series is based on the Christian Eggers PTP support for KSZ9563.
Applied the Christian patch and updated as per the latest refactoring of KSZ
series code. The features added on top are PTP packet Interrupt
implementation based on nested handler, LAN937x two step timestamping and
programmable per_out pins.

[Patch net-next v1 01/12] net: dsa: microchip: ptp: add the posix clock support

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

This patch implement routines (adjfine, adjtime, gettime and settime)
for manipulating the chip's PTP clock. It registers the ptp caps
to posix clock register.

[Patch net-next v1 02/12] net: dsa: microchip: ptp: Initial hardware time stamping support

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

This patch adds the routine for get_ts_info, hwstamp_get, set. This enables
the PTP support towards userspace applications such as linuxptp.
Tx timestamping can be enabled per port and Rx timestamping enabled
globally.

[Patch net-next v1 03/12] net: dsa: microchip: ptp: add 4 bytes in tail tag when ptp enabled

[Arun Ramadoss]

If PTP is enabled in the hardware, then 4 bytes are added in the tail
tag. When PTP is enabled and 4 bytes are not added then messages are
corrupted.

[Patch net-next v1 04/12] net: dsa: microchip: ptp: Manipulating absolute time using ptp hw clock

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

This patch is used for reconstructing the absolute time from the 32bit
hardware time stamping value. The do_aux ioctl is used for reading the
ptp hardware clock and store it to global variable.
The timestamped value in tail tag during rx and register during tx are
32 bit value (2 bit seconds and 30 bit nanoseconds). The time taken to
read entire ptp clock will be time consuming. In order to speed up, the
software clock is maintained. This clock time will be added to 32 bit
timestamp to get the absolute time stamp.

[Patch net-next v1 05/12] net: dsa: microchip: ptp: enable interrupt for timestamping

[Arun Ramadoss]

PTP Interrupt mask and status register differ from the global and port
interrupt mechanism by two methods. One is that for global/port
interrupt enabling we have to clear the bit but for ptp interrupt we
have to set the bit. And other is bit12:0 is reserver in ptp interrupt
registers. This forced to not use the generic implementation of
global/port interrupt method routine. This patch implement the ptp
interrupt mechanism to read the timestamp register for sync, pdelay_req
and pdelay_resp.

[Patch net-next v1 06/12] net: ptp: add helper for one-step P2P clocks

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

For P2P delay measurement, the ingress time stamp of the PDelay_Req is
required for the correction field of the PDelay_Resp. The application
echoes back the correction field of the PDelay_Req when sending the
PDelay_Resp.

Some hardware (like the ZHAW InES PTP time stamping IP core) subtracts
the ingress timestamp autonomously from the correction field, so that
the hardware only needs to add the egress timestamp on tx. Other
hardware (like the Microchip KSZ9563) reports the ingress time stamp via
an interrupt and requires that the software provides this time stamp via
tail-tag on tx.

In order to avoid introducing a further application interface for this,
the driver can simply emulate the behavior of the InES device and
subtract the ingress time stamp in software from the correction field.

On egress, the correction field can either be kept as it is (and the

the correction field back to the tail-tag.

Changing the correction field requires updating the UDP checksum (if UDP
is used as transport).

[Patch net-next v1 07/12] net: dsa: microchip: ptp: add packet reception timestamping

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

This patch adds the routines for timestamping received ptp packets.
Whenever the ptp packet is received, the 4 byte hardware time stamped
value is append to its packet. This 4 byte value is extracted from the
tail tag and reconstructed to absolute time and assigned to skb
hwtstamp.

[Patch net-next v1 08/12] net: dsa: microchip: ptp: add packet transmission timestamping

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

This patch adds the routines for transmission of ptp packets. When the
ptp pdelay_req packet to be transmitted, it uses the deferred xmit
worker to schedule the packets.
After the packet is transmitted, ISR is triggered. The time at which
packet transmitted is recorded to separate register.
This value is reconstructed to absolute time and posted to the user
application through socket error queue.

[Patch net-next v1 09/12] net: dsa: microchip: ptp: move pdelay_rsp correction field to tail tag

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

For PDelay_Resp messages we will likely have a negative value in the
correction field. The switch hardware cannot correctly update such
values (produces an off by one error in the UDP checksum), so it must be
moved to the time stamp field in the tail tag. Format of the correction
field is 48 bit ns + 16 bit fractional ns.  After updating the
correction field, clone is no longer required hence it is freed.

[Patch net-next v1 10/12] net: dsa: microchip: ptp: add 2 step timestamping for LAN937x

[Arun Ramadoss]

LAN937x series of switches support 2 step timestamping mechanism. There
are timestamp correction calculation performed in ksz_rcv_timestamp and
ksz_xmit_timestamp which are applicable only for p2p1step. To check
whether the 2 step is enabled or not in tag_ksz.c introduced the helper
function in taggger_data to query it from ksz_ptp.c. Based on whether 2
step is enabled or not, timestamp calculation are performed.

[Patch net-next v1 11/12] net: dsa: microchip: ptp: add periodic output signal

[Arun Ramadoss]

From: Christian Eggers <ceggers@arri.de>

LAN937x and KSZ PTP supported switches has Three Trigger output unit.
This TOU can used to generate the periodic signal for PTP. TOU has the
cycle width register of 32 bit in size and period width register of 24
bit, each value is of 8ns so the pulse width can be maximum 125ms.

Tested using ./testptp -d /dev/ptp0 -p 1000000000 -w 100000000 for
generating the 10ms pulse width

[Patch net-next v1 12/12] net: dsa: microchip: ptp: add support for perout programmable pins

[Arun Ramadoss]

There are two programmable pins available for Trigger output unit to
generate periodic pulses. This patch add verify_pin for the available 2
pins and configure it with respect to GPIO index for the TOU unit.

PTP_WRITE_TIME sounds more intuitive than PTP_LOAD_TIME?
Also I see that all the #defines are introduced in this patch, some of
which are used later. It is a good idea to introduce the #defines in
the same patches where they are being used for the first time.
I will be looking at the entire series but am responding to this now.

PTP_LOAD_TIME has been derived from the data sheet:

-------------8<--------------
PTP Clock Load
--------------
Setting this bit will cause the PTP clock to be loaded with the time value in
registers 0x0502 to 0x050B.
------------->8--------------

I would also prefer PTP_WRITE_TIME. But is it ok to deviate from data sheet?

If I understand this correctly, the software clock is updated with
full 64b every 1s. However only 32b timestamp registers are read while
processing packets and higher bits from this clock are used.
How do you ensure these higher order bits are in sync with the higher
order bits in the HW? IOW, what if lower 32b have wrapped around and
you are required to stamp a packet but you still don't have aux worker
updated.

I see that the hwts_rx_en gets removed in the later patch. Instead you
could add rx filters support only later when you have the final code
in place.

Should be -EOPNOTSUPP ? I see some other places where -EOPNOTSUPP is
more appropriate.

The Ptp Hardware Clock (PHC) seconds register is 32 bit wide. To have
register overflow it takes 4,294,967,296 seconds which is approximately
around 136 Years. So, it is bigger value and assume that we don't need
to care of PHC second register overflow.
For the packet timestamping, value is read from 32 bit register. This
register is splited into 2 bits seconds + 30 bits nanoseconds register.
In the ksz_tstamp_reconstruct function, lower 2 bits in the ptp_data-
>clock_time is cleared and 2 bits from the timestamp register are
added. 

 spin_lock_bh(&ptp_data->clock_lock);
 ptp_clock_time = ptp_data->clock_time;
 spin_unlock_bh(&ptp_data->clock_lock);

/* calculate full time from partial time stamp */
 ts.tv_sec = (ptp_clock_time.tv_sec & ~3) | ts.tv_sec;

In RFC v2, this patch 2 and next patch 3 are in single patch. There are
two simple reasons, I had splitted them two. One is to have logical
commit and ease of code review. Patch 2 will add the hwtstamp_set and
get dsa hooks and patch 3 to mechanism to coordinate with the tag_ksz.c
to add additional 4 bytes in tail tag when PTP is enabled based on
tagger_data.
Second reason to split is to have patch authorship. I had used the
Christian Eggers patch and extending support for LAN937x. In the
initial series, it has dsa_port->priv variable to store the
ptp_shared_data. Now priv variable is removed from dsa_port so I used
tagger_data based on sja1105 implementation. As it is different from
intial patch series, moved to separate patch.

I got a offline comment like This check is probably redundant (already
checked in period_store() and ptp_ioctl()). I am looking into whether
this check is required or already handled in upper layers.
If the check is required, then I feel -EINVAL/-ERANGE should be
reasonable. Because we are supporting periodic output only thing is
index is out of bound. If we return -EOPNOTSUPP, it indicates we are
not supporting periodic output.

Ok. I will update -EINVAL to -EOPNOTSUPP.

To have similar naming convention between code and Datasheet it is
named as Load time.

The patches are splitted into multiple smaller patches for review. I
missed to move header file defines to appropriate patches. Sure I will
move it.

OK thanks. Looks like nano sec and seconds are not being stitched, if
that had happened the rollover would be very frequent. But stitching
the seconds with higher bits still has this problem.
But it should be OK since the window is so large.

It depends. When the datasheet has succint and uniquely identifiable
names for registers, there's no reason to not use them. Exceptions are
obnoxious things like "BASIC_MODE_CONTROL_REGISTER" or "MDIO_CONTROL_1"
which get abbreviated in kernel code to "BMCR" and "MDIO_CTRL1".

When the register names in the datasheet are literally prose ("PTP Clock Load",
with spaces and all), some divergence from the datasheet will have to
exist no matter what you do. So I guess you can just go for what makes
the most sense and is in line with existing kernel conventions. People
who cross-reference kernel definitions with the datasheet will still
have a hell of a life, but hey, you can tell them it's not your fault
you can't name a C variable "PTP Clock Load".

OTOH, I don't find "PTP_LOAD_TIME" unintuitive, but I won't oppose a
rename if there's agreement from people who care more than me.

Is the colon misplaced? What do you want to say, "can't rmw 16bit reg: 0x0 -EIO",
or "can't rmw 16bit reg 0x0: -EIO"?

Reminds me of a joke:

I would avoid naming labels with "error_", if the success code path is
also going to run through the code they point to. "goto unlock" sounds
about right.

Is it a conscious decision to have this structure declared here in the
.rodata section (I think that's where this goes?), when it will only be
used as a blueprint for the implicit memcpy (struct assignment) in
ksz_ptp_clock_register()?

Just saying that it would be possible to initialize the fields in
ptp_data->caps even without resorting to declaring one extra structure,
which consumes space. I'll leave you alone if you ACK that you know your
assignment below is a struct copy and not a pointer assignment.

Registering a structure with a subsystem generally means that it becomes
immediately accessible to user space, and its (POSIX clock) ops are callable.

You haven't explained what PTP_802_1AS does, concretely, even though
I asked for a comment in the previous patch set. Is it okay for the PTP
clock to be registered while the PTP_802_1AS bit hasn't been yet written?
The first few operations might take place with it still unset.

I know what 802.1AS is, I just don't know what the register field does.

Variable named "en" (enable) which takes the values 0 or 2? Not good.
Also, why is the type not enum hwtstamp_tx_types, but u8? Can't you name
this "enum hwtstamp_tx_types tx_type"?

I'm not sure that this mutex serves any purpose at all?

One could have argued that concurrent calls to ksz_hwtstamp_get()
shouldn't be able to see incoherent values of prt->hwts_tx_en and of
prt->hwts_rx_en.

But ksz_hwtstamp_get() doesn't acquire this mutex, so that is not true,
this isn't why the mutex is acquired here. I don't know why it is.

Comment in the code please. Also, please spell it out explicitly that
the tail tag size changes for all TX packets, PTP or not, if PTP
timestamping is enabled. Your phrasing can be unclear and the reader may
think that only PTP packets require a larger tail tag.

Let's be clear, hwtstamp_get_state() deals with TX timestamping, and
config.rx_filter deals with RX timestamping. Don't mix the two.
Using custom programs like testptp, you can enable RX timestamping but
not TX timestamping, or the other way around. You don't want the driver
to get confused.

>  		config.rx_filter = HWTSTAMP_FILTER_ALL;

Can the switch provide RX timestamps for all kinds of Ethernet packets,
not just PTP? If not, then report just what it can timestamp.

As discussed, I don't really think there exists a case for hwtstamp_get_state().

Stronger. Time stamp tag *needs* to be inserted if PTP is enabled in hardware.
Regardless of whether this is a PTP frame or not.

I think you don't think this is confusing. But it is confusing.
2 years from now, when this patch gets submitted again for being merged,
I don't want to ask the same questions again.

Why don't you call ksz_ptp_gettime(ptp, &ts) directly?

Does ksz_ptp_start_clock() race with anything? The PTP clock has not
even been registered by the time this has been called. This is literally
an example of the "spin_lock_init(); spin_lock();" antipattern.

Its a copy paste problem. I reused the exisiting inline functions based

Ok. I will rename the goto block.

To reduce number of line in the ksz_ptp_clock_register(), I moved the
structure intialization outside of function. Referred other dsa
implementation found this type in
drivers/net/dsa/ocelot/felix_vsc9959.c, just reused it.
I didn't thought of .rodata section and memcpy overhead.

I will move this initialization within ksz_ptp_clock_register.

I overlooked the comment in the previous patch set. Christian also gave
offline comment that, this bit is reserved in KSZ9563 datasheet. 
This bit should be set whenever we operate in 802.1AS(gPTP). 
When this bit, then all the PTP packets will be forwared to host port
and none to other ports.
After changing my patch to include 1 step timestamping, I think it
should be set only for LAN937x 2 step mode.

Mutex is not needed. I will remove it.

I will elaborate the commit description, why the additional 4 bytes are
required.

Initially I thought like using one variable in tagger_data to control
the whether to add 4 bytes in tail tag or not. And another variable in
ksz_port to check whether rx timestamping enabled or not. 
To avoid using two variables to track the timestamping, I thought
reusing the tagger variable to check rx timestamping as well as PTP
enabled in hardware.

I need to change algorithm such a way that, 
- When either Tx timestamping or Rx timestamping enabled in any one of
the port, enable PTP in hardware and add 4 additional bytes in tail
tag.
- Add hwtstamp_config variable in ksz_port, to set and get the hwtstamp
configuration.

The interrupts are added in the following patches in the series. During
the deferred packet timestamping, partial timestamps are reconstructed
to absolute time using the ptp_data->clock_time in the bottom halves.
So we need this spin_lock_bh.
