[PATCH 0/9] i2c: rcar: tackle race conditions in the driver

[PATCH 0/9] i2c: rcar: tackle race conditions in the driver

[Wolfram Sang]

Hello RCar Fans!

Two issues people have seen with the i2c-rcar driver was:

a) immediately restarted messages after NACK from client
b) duplicated data bytes in messages

Some people already worked on those and had a tough time because it was hard to
reproduce these issues on non-customer setup. Luckily, I somewhen had a state
where the first transfer after boot would always show the above issues on a
plain Renesas Lager board. When measuring, I found a third issue thanks to my
new tool 'i2ctransfer' (and thanks to projects like sigrok and OpenLogicSniffer,
of course. Thank you very much!):

c) after read message, no repeated start was sent, but stop + start.

Due to some unlucky design choices in the IP core, it has some race windows
which can cause problems if interrupts get delayed. Also, for every new message
in one transfer, context switches between interrupt and process were needed.

So I refactored the driver to setup new messages in interrupt context, too.
This avoids the race for b) because we are now setting up the new message
before we release the i2c bus clock (before we released the clock and set up
the message in process context). c) is also fixed, this was not a race but a
bug in the state handling. a) however is not fixed 100% :( We have the race
window as small as possible now when utilizing interrupts, so it is an
improvement and worked for my test cases well. There were experiments by me and
Renesas engineers to use polling to prevent the issue but this caused other
side effects, sadly. So, let's improve the situation now and let's see where we
get.

I did quite some lab testing here and also verified that slave support does not
suffer from these changes. However, I'd really appreciate if people could give
this real-world-testing which is always different.

Please have a look, a test, etc...

Thanks,

   Wolfram

[PATCH 1/9] i2c: rcar: rework hw init

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

We don't need to init HW before every transfer since we know the HW
state then. HW init at probe time is enough. While here, add setting the
clock register which belongs to init HW. Also, set MDBS bit since not
setting it is prohibited according to the manual.

[PATCH 6/9] i2c: rcar: don't issue stop when HW does it automatically

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

The manual says (55.4.8.6) that HW does automatically send STOP after
NACK was received. My measuerments confirm that.

[PATCH 3/9] i2c: rcar: remove spinlock

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

We make sure to reinit the HW in the timeout case; then we know that
interrupts are always disabled in the sections protected by the
spinlock. Thus, we can simply remove it which is a preparation for
further refactoring. While here, rename the timeout variable to
time_left which is way more readable.

[PATCH 5/9] i2c: rcar: init new messages in irq

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

Setting up new messages was done in process context while handling a
message was in interrupt context. Because of the HW design, this IP core
is sensitive to timing, so the context switches were too expensive. Move
this setup to interrupt context as well.

In my test setup, this fixed the occasional 'data byte sent twice' issue
which a number of people have seen. It also fixes to send REP_START
after a read message which was wrongly send as a STOP + START sequence
before.

I'm afraid this patch has been found by git bisect to break HDMI on Koelsch 
:-( 

The regmap_read(adv7511->regmap, ADV7511_REG_CHIP_REVISION, &val) call in 
drivers/gpu/drm/i2c/adv7511.c returns -ENXIO.

Reverting the patch on top of Geert's current drivers master branch fixes the

I know :-)

Do you have a Koelsch board now ? Could you try 
b9653e9c000dc2ebd9c8712442c659ccd1586e22 from Geert's drivers tree ? On my 
board the adv7511 fails to probe completely due to the regmap_read() failure.

Nope, I only have Lager. I'd be surprised if it really was a Koelsch
only issue, though...

drivers/gpu/drm/drm_fb_helper.c: In function 'restore_fbdev_mode':
drivers/gpu/drm/drm_fb_helper.c:448:5: error: 'error' undeclared (first use in this function)

??

I fixed it locally and will see if I see ADV7511 problems. I cannot
fully test HDMI probably, because it seems that this HDMI->DVI chain I
have does not work. Tested that with a kernel which used to work in
Dublin. Need to get another HDMI device.

Okay, so before any 'modetest' activity. Which kernelconfig?
shmobile_defconfig?

Thanks,

I had CONFIG_DRM_FBDEV_EMULATION disabled. I've then enabled it but also 
merged git://people.freedesktop.org/~airlied/linux next in my branch, which 
probably fixes the problem.

It's supposed to be supported, so that might be something we need to fix. More 
work for me \o/ :-)

That one also probes for me... I only disabled DHCP and added my
initramfs. I patched the fbdev build error out and changed Lager dts to
use i2c-rcar (instead of i2c-sh_mobile).

Can you enable CONFIG_I2C_DEBUG_CORE in the config, apply this patch,
and send me the trace output and bootlog?

Thanks,

I've tested it on renesas-drivers-2015-10-13-v4.3-rc5 without 
CONFIG_DRM_FBDEV_EMULATION, explaining why it compiled properly for me.

Best report ever: I simply don't get a picture :) No warnings, no
messages. I think we want to make sure my HDMI->DVI converter is proper,
though.

I made the ADV7180 and AK4642 built-in and this kernel still probes
rcar-du on my Lager and Magnus' Koelsch...

So, here is the NACK bit set. Which does not happen on my Lager and
Magnus' Koelsch. I am starting to wonder if you have a board with HW
issues? Could it be another I2C device interfering? Do you happen to
know if you have an earlier revision of Koelsch?

Thanks,

It's CONFIG_DRM_I2C_ADV7511 that you need for HDMI output.

I have ADV7180 and AK4642 built as modules in my kernel.

I borrowed another HDMI monitor. There, my Lager board produces proper
HDMI output, both with plain HDMI connection as well as with the
HDMI->DVI converter. No I2C issues.

Seems I have to dump this other monitor which didn't even display the
output of the Chromecast I had lying around.

Tricky. Your binary kernel didn't even start on first try on my Lager
and Magnus' Koelsch. Will check that again tomorrow.

Can you try this patch I just sent out?

"i2c: rcar: make sure clocks are on when doing hw init"

We know that Koelsch boards have different bootloaders leaving the
clocks in different states. What you see could be the result of a
disabled clock.

[PATCH 8/9] i2c: rcar: revoke START request early

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

If we don't clear START generation as soon as possible, it may cause
another message to be generated. To keep the race window as small as
possible, we clear it right at the beginning of the interrupt. We don't
need checking since we always want to stop START and STOP generation on
the next occasion after we started it.

This patch improves the situation but sadly does not completely fix it.
It is still to be researched if we can do better given this HW design.

[PATCH 8/9] i2c: rcar: revoke START request early

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

If we don't clear START generation as soon as possible, it may cause
another message to be generated. To keep the race window as small as
possible, we clear it right at the beginning of the interrupt. We don't
need checking since we always want to stop START and STOP generation on
the next occasion after we started it.

This patch improves the situation but sadly does not completely fix it.
It is still to be researched if we can do better given this HW design.

Does that mean that, due to hardware design, it's impossible to use I2C 
interrupts in a race-free way ? It would be interesting to document why in a 
commit log message, or possibly in the code itself.

I surely hope so. I can't test because I don't have Koelsch.

It can maybe be done when polling. However, this might need busy looping
for ~1us. Also, the repeated start handling needs to be rewritten and I
am not sure this goes well with polling.

I'll test it ASAP, but that might take a while as I'm busy with VSP+DU on Gen3 
now.

I meant without polling. Does the hardware design prevent from using I2C in 
interrupt mode in a race-free way ?

I'll test it ASAP, but that might take a while as I'm busy with VSP+DU on Gen3

I meant without polling. Does the hardware design prevent from using I2C in 
interrupt mode in a race-free way ?

Yes, when we get a NACK after address phase. HW automatically creates a
STOP condition after a NACK. After this STOP, if we haven't been fast
enough to clear the ESG bit (which started the address phase), then it
will be still set and a new message will be created.

FYI, I have enabled Koelsch remote access on port 8001 if you want to
give it a shot!

Yes, now a HD-ready TV is hooked up. It should give you something over
EDID. Let me know when you're done and I'll move things back.

'No EDID data' says bootlog. Also, all 0 when reading that i2c client
address afterwards. I don't see or sense anything suspicious with the
I2C transfers itself from remote.

And could you maybe install a local TFTP server on your next images? :)

Did you use the DRM/KMS modetest program to display stuff on the HDMI
monitor? To trigger the error case you need to a couple of steps -
just booting the kernel does not trigger things. The EDID provided by
the HDMI monitor is read out by the HDMI encoder chip that in turn is
connected over I2C to the SoC. I believe the connection between the
HDMI monitor and the HDMI encoder chip works ok, but the bits between
the HDMI encoder chip and the I2C master on the SoCs may need some
more attention.

This was done by Geert earlier. Lets discuss details over IRC!

Nope, I have to admit I assumed when the kernel says that it has no EDID
data that it would have triggered reading the data from the monitor.

I understood that the encoder needs a trigger to read the data. It then
provides EDID data via a special I2C device address. That is read by a
simple 64-byte I2C read transfer which I didn't have issues with here.
And reading it byte-per-byte gave the same results.
