[PATCH] drm/omap: Migrate minimum FCK/PCK ratio from Kconfig to dts

[PATCH] drm/omap: Migrate minimum FCK/PCK ratio from Kconfig to dts

[Adam Ford]

Currently the source code is compiled using hard-coded values
from CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK.  This patch allows this
clock divider value to be moved to the device tree and be changed
without having to recompile the kernel.

I understand why you want to do this, but I'm not sure it's a good idea. 
It's really something the driver should figure out, and if we add it to 
the DT, it effectively becomes an ABI.

That said... I'm not sure how good of a job the driver could ever do, as 
it can't know the future scaling needs of the userspace at the time it 
is configuring the clock. And so, I'm not nacking this patch, but I 
don't feel very good about this patch...

The setting also affects all outputs (exluding venc), which may not be 
what the user wants. Then again, I think this setting is really only 
needed on OMAP2 & 3, which have only a single output. But that's the 
same with the current kconfig option, of course.

So, the current CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK is an ugly hack, in my 
opinion, and moving it to DT makes it a worse hack =). But I don't have 
any good suggestions either.

As it stands the Logic PD OMAP35 and AM37/DM37 boards (SOM-LV and
Torpedo) require this to be hard coded to 4 or it hangs during start.
This is the case for all versions 4.2+.  I haven't tested it with
older stuff.  Tony has a DM3730 Torpedo kit and reported the hanging
issue to me. I told him to set that value to 4 to make it not hang.
He asked that I move it to the DT to avoid custom kernels.  I agree
it's a hack, but if it's create a customized defconfig file for 4
boards or modify the device tree, it seems like the device tree
approach is less intrusive.

Well, if this boards needs a factor 4 to be defined, it is IMHO
100 % correct to describe this in the DTS and nowhere else. Like
minimum and maximum voltage of a regulator which is also very board
specific.

Unless it can be figured out automatically. If it turns out later
that it can, I would assume the drivers can simply ignore the hint
in the DTS?

Just my 2cts without knowing details and having tested anything
on our DM37 boards.

Nikolaus

Ok, well, I think that's a separate thing from its intended use. The 
point of the kconfig option is to ensure that the fclk/pclk ratio stays 
under a certain number to allow enough scaling range. It should never 
affect a basic non-scaling use case, unless you set it to a too high 
value, which prevents finding any pclk.

Has anyone debugged why the hang is happening?

If we can't fix the bug itself, rather than adding a DT option, we could 
change add a min_fck_per_pck field (as you do), keep the kconfig option, 
and set the min_fck_per_pck based on the kconfig option, _or_ in case of 
those affected SoCs, set the min_fck_per_pck even without the kconfig 
option.

I tried debugging this years ago, and I was told to use the
CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK.

I am just curious if anyone else sees this.  If nobody is using this
hack, I wonder how much of the impact it will be.  I'm trying trying
to get my board to boot without hanging without creating a custom
defconfig.

Assuming this patch progresses, this needs a vendor prefix and please 
split bindings to separate patch.

I started to debug this, but I got distracted when I noticed the LCD
did't work at all on modern kernels.  I have that fixed now, so I can
go back to investigating this.

** hang **

I noticed there doesn't seem to be the calculation for setting fck,
pck or any of the timings.  Are there any more debug options I can
enable?

I would prefer to fix the calculation so the display can work without
the defconfig or device tree modification, and then we dump this all
together.

The logs here look very different. The first one doesn't even show the 
DSS rev prints. Can you get full logs for both? And even better, if you 
can build omapdss as a kernel module, and load it after the boot, you 
won't have any "extra" going on at the same time.

And what is the hdmi5_configure there? I don't see anything in the 
driver that would print hdmi5_configure. And, of course, there's no 
hdmi5 on that platform. Hmm, ok... it's from component.c, using "%ps". 
Somehow that goes wrong. Which is a bit alarming, but perhaps a totally 
different issue.

The hang happens at an odd time. The last line shows that the driver has 
managed to do its work at suspend time. Afaics, the only thing the 
driver does after that is calling pinctrl_pm_select_sleep_state(). You 
could add a print after that to be sure that goes fine. But I suspect it 
does.

Which then hints that the hang is somewhere outside the driver, in 
omap_device perhaps?

You could try adding an extra call to dss_runtime_get(). Say, at the 
beginning of dss_probe_hardware(), do another dss_runtime_get(). That 
should force DSS to be always on (until reboot). runtime PM suspend 
related bugs should disappear.

Since it's build as a module, I only dumped the stuff starting after
the modules are loading.  I can provide more if you want, but I am
trying to avoid excessive noise.

I'll try to take a look later.  For Logic PD distributions, we create
a custom defconfig with all those drivers removed, so I'm not worked
up about it, but it would be nice to not call drivers that don't
exist.

Thanks for reviewing this.  I've been coping for a while by manually
changing the config option, but with 5.4 being the expected next LTS,
I was hoping to address this so I don't have to keep working around
it.

I'll send out a second e-mail with some of your suggestions, but I
don't want to litter this e-mail with too many logs.

So you have CONFIG_OMAP5_DSS_HDMI=n? Then it's even more disturbing, as 
there's no way the string "hdmi5_configure" can be in the kernel image...

Maybe it's nothing, but... It's just so odd.

I dont' have the same board, but I was testing with omap3 beagle xm. I 
can reproduce rather similar issue, although I don't get a hang but 
instead sync lost and underflow flood (which makes the device unusable).

It looks like a bug in omap clock handling.

DSS uses dss1_alwon_fck_3430es2 as fclk. dss1_alwon_fck_3430es2 comes 
from dpll4_ck, and there's a divider after the PLL, dpll4_m4_ck.

When the DSS driver sets dss1_alwon_fck_3430es2 rate to 27000000 or 
27870967, which can be created with m4 dividers 32 and 31, it looks like 
the divider goes to bypass, or to a very small value. DSS gets a very 
high clock rate and breaks down.

For the logs and problems I am showing in this thread, I am using a
stock omap2plus_defconfig which has it enabled.  I was only trying to
state that I am not worried about the omap5 hdmi stuff, because when I
do a custom distribution for Logic PD, I remove those config options
to make the issue go away.
>
> Maybe it's nothing, but... It's just so odd.

I don't think we need to worry about it now.  Ideally, it would be
nice to have the drivers recognize they are not needed and or setup
the Kconfig options to make these drivers dependent on the platforms
that support it so unselecting OMAP5 could make the omap5 options
disappear.

Sorry if I accidentally threw in a distraction or confusion.

Is there anything I can do to help troubleshoot this?  I could insert
a hack that checks if we're omap3 and if so make the divider equal to
4, but that seems like just a hack.
I can run more tests or insert code somewhere if you want.

My point is that something is bugging there. It should not print 
hdmi5_configure, regardless of setup or platform. If I'm not mistaken, 
it should print "dispc_component_ops". But somehow it gets a wrong 
symbol string.

But yes, I'm 99.9% sure it's not related, so let's ignore it here =).

I think it's up to someone who's knowledgeable in omap clock framework. 
I'm kind of hoping that Tero or Tony would be willing to debug =). I can 
try to find time to debug the omap clk framework, but I'll be going on 
blindly there.

If you can provide details about what clock framework / driver does 
wrong (sample clk_set_xyz call sequence, expected results via 
clk_get_xyz, and what fails), I can take a look at it. Just reporting 
arbitrary display driver issues I won't be able to debug at all (I don't 
have access to any of the displays, nor do I want to waste time 
debugging them without absolutely no knowledge whatsoever.)

I used your hack patches to allow changing rates via debugfs. And set 
dss1_alwon_fck_3430es2 to 27000000 or 27870967. The end result was that 
DSS gets some very high clock from dss1_alwon_fck_3430es2, as the frame 
rate jumps to many hundreds fps.

So, these numbers are not real, but to give the idea what I saw. Running 
first with 50 MHz, I can see, say, 40 fps. Then I set the clock to 30 
MHz, and fps dropped to, say, 30fps, as expected with lower clock. Then 
I set the clock to 27MHz (or the other one), expecting a bit lower fps, 
but instead I saw hundreds of fps.

I don't know if there's any other way to observe the wrong clock rate 
but have the dss enabled and running kmstest or similar. I can help you 
set that up next week, should be trivial. You don't need a display for that.

Here's how to reproduce. I have the attached patches. Three of them are 
the clk-debug ones, and one of mine to make it easy to test without a 
display, and without underflow flood halting the device. There are on 
top of v5.3. Kernel config also attached.

kmstest is from kms++ project (https://github.com/tomba/kmsxx). It 
should be straightforward to compile, but kmstest binary is also 
included in TI's rootfs.

I boot up, and run this in one terminal:

# kmstest -c dvi -r 640x480 --flip

It shows ~60 fps, as expected:

Connector 0: fps 60.499982, slowest 16.72 ms

In another terminal:

# cd /debug/clk/dss1_alwon_fck_3430es2/
# cat clk_rate
50823530
# echo 30000000 > clk_rate

Now with lower clock, the fps dropped as expected:

Connector 0: fps 35.468961, slowest 28.41 ms

Then:

# echo 27000000 > clk_rate

And fps goes through the roof and underflows start to come:

Connector 0: fps 514.734527, slowest 2.11 ms

I don't know what exactly goes on here, but 514 fps matches quite 
exactly the PLL/2 rate:

864000000/2/2/((640+16+96+48)*(480+10+2+33)) = 514.2857142857143

(The second /2 there is DSS's internal pclk divider)

Subject: [PATCH 3/4] clk: debug: add support for enabling / preparing clocks
 manually

Add support for enabling / disabling clocks manually from debugfs.
Setting 1 to prepare/enable counts calls corresponding enable routine
once, incrementing the usecounts by 1. Setting the same files as -1
does the unprepare / disable call similarly. Reading both files
returns the current usecount, as is done without this patch.

Ok, I ignored all your test code and just fiddled with my trusty clk 
debugfs patches. I don't like debugging with test code I have no 
experience with. :)

Anyways, it seems the dpll4_m4_ck max divider value is wrong, it only 
accepts values upto 16 at least on my board. The setting for this in DT 
is 32, and it is most likely SoC specific what happens if you write an 
invalid value to the divider.

The best action here is probably to drop the max-div value for this 
clock to 16. Can someone check this with their display setup and see 
what happens? Attached patch should do the trick.

Subject: [PATCH 1/1] ARM: dts: omap3: fix DPLL4 M4 divider max value

The maximum divider value for DPLL4 M4 divider appears wrong. For most
OMAP3 family SoCs this is 16, but it is defined as 32, which is maybe
only valid for omap36xx. To avoid any overflows in trying to write this
register, set the max to 16 for all omap3 family.

I tried your attached patch on my dm3730 and that seems to make it
somewhat better in that it doesn't hang anymore, so that leads me to
believe that your comment about the divider being only valid on the
omap36 may not be true. I do think it solves the hanging issue that i
was seeing, but I now see a new one now which is dumping a backtrace.

It looks like it's unhappy that its trying to get one frequency and
getting something different instead.

[   10.014099] WARNING: CPU: 0 PID: 111 at
drivers/gpu/drm/omapdrm/dss/dss.c:655 dss_set_fck_rate+0x70/0x90
[omapdss]
[   10.014129] clk rate mismatch: 27870968 != 27000000

See attached log for the full dump.

Either way, I think you've identified the main issue.  I just think we
may have uncovered another one in the process.

For what it's worth, the video looks good.  :-)

I believe this one is for Tomi to comment, his driver does some magic 
compares for the requested vs. actual received clock rates. If I am not 
mistaken, we are only modifying an integer divider here, and thus it is 
physically impossible to get accurate 27MHz rate to display.

I didn't expect exactly 27MHz,but the back trace is what concerns me more.

However, looking at
# cat clk/dpll4_ck/clk_rate
864000000

It seems like 864000000 / 32 would be 27 MHz, but instead we're
dividing it by 31 yielding 27870968.  I don't know the clocking
architecture, so I don't know what your patch actually did or how the
divide by 16 limit worked into this.  If lck cannot divide by 32, it
would be nice to see if it could divide by 27 to get to 32MHz.  From
there, the pck could then divide by 4 yielding 9MHz.

Ah sorry... DSS driver knows the max divider value, so that it can 
iterate over all the rates to find a good one.

I'll send a patch later, but look for omap3630_dss_feats in dss.c, and 
change fck_div_max from 32 to 16.

That's pretty odd. With Tero's patch (I didn't test it though) the max 
divider should be 16. So the minimum fclk rate should be 54MHz. But 
somehow the clock framework managed to produce 27870968...

I have checked on GTA04 and OpenPandora (DM3730 resp. OMAP3430) and did not notice a negative effect.

(Well, we never see the problem that is discussed here and have built with CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK=0).

I have never been able to use CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK=0, but
I assume it's either a function of pck or a combination of pck with
the resolution.

Based on Tomi's comment, I assume he's working on the following.  Can

Hopefully it doesn't break the 3630 for you, but it fixed my issue
with no back trace:

[    9.915588] DSS: set fck to 54000000
[    9.915618] DISPC: lck = 54000000 (1)

[    9.917663] DISPC: pck 9000000

I do wonder, however if there is a divider that is higher than 16, but
lower than 32.
I was able to run fck at 36MHz before with divide by 4 to 9MHz, so I
am hoping that by running at 54MHz / 6 doesn't draw more power.  I was
reading through the datasheet, but I could not find any reference to
the max divider.

For run, I tested a max divider of 27, and I was able to get it
functional with a slower fck

[    9.939056] DSS: set fck to 36000000
[    9.939086] DISPC: lck = 36000000 (1)

I don't know the implications, so if the people from TI say stick with
16, I'm fine with that, but at least there is some evidence that it
can be higher than 16, but lower than 32.

Sorry for all the spam, but I moved both of them to 31 from 32, and it
also seems to work successfully at 31.

Let's see what Tero says, but yeah, something is odd here. I expected 
the max divider to be 16 with Tero's patch, but I don't see it having 
that effect. I can get the div to 31.

You can see this from the clock register 0x48004e40 (CM_CLKSEL_DSS). The 
lowest bits are the divider, 5 to 0. The TRM says max div is 32.

Tero said for him the dividers > 16 didn't "stick" to the register. I'm 
now wondering if he has an old beagleboard with OMAP34xx, which has max 
div 16.

So testing a bit more here, I can see the DSS working fine and fps as 
expected when I write values directly to CM_CLKSEL_DSS:5:0, with 
dividers up to 31. With 32, DSS breaks. The TRM (AM/DM37x) says value 32 
is valid.

Just a blind guess: is there something in the errata to take care of?

I wonder if it's somehow being masked with bits 4:0 instead of 5:0
which could potentially make the divider 0 and that value doesn't
appear to be valid.

Hmmh, after some testing, it seems there is bad stuff happening with the 
divider clock implementation, I am re-working it as of now. Basically 
what is wrong is that with a divider max value of say 16, the driver 
attempts to craft the max value into a mask, but this ends up being 
0x1f. If the max value is 15, it ends up into 0xf which is correct.

Ok, that explains the max not working.

It doesn't explain the other issue, where the TRM says the max div is 
32, but it does not work. But taking the max div from the old SoCs, 16, 
is not correct either, as it seems that dividers up to 31 work ok.

If someone knows for sure that dividers higher than 16 are fine on 
omap36xx, we can add this under omap36xx-clocks.dtsi. Anyway, let me fix 
the broken divider max logic first, that seems to be more pressing issue.

Ok, attached a series that hopefully fixes it, any testing feedback 
welcome before I post this properly.

This also supports omap36xx dpll4_m4_ck divider up-to 31, other omap3 
family is limited to 16.

Subject: [PATCH 2/4] clk: ti: divider: cleanup ti_clk_parse_divider_data API

Cleanup the ti_clk_parse_divider_data to pass the divider data struct
directly instead of individual values of it. This makes it easier
to modify the implementation later on.

Subject: [PATCH 3/4] clk: ti: divider: convert to use min,max,mask instead of
 width

The existing width field used to check divider validity does not provide
enough protection against bad values. For example, if max divider value
is 4, the smallest all-1 bitmask that can hold this value is 7, which
allows values higher than 4 to be used. This typically causes
unpredictable results with hardware. So far this issue hasn't been
noticed as most of the dividers actually have maximum values which fit
the whole bitfield, but there are certain clocks for which this is a
problem, like dpll4_m4 divider on omap3 devices.

Thus, convert the whole validity logic to use min,max and mask values
for determining if a specific divider is valid or not. This prevents
the odd cases where bad value would otherwise be written to a divider
config register.

Subject: [PATCH 4/4] ARM: dts: omap3: fix DPLL4 M4 divider max value

The maximum divider value for DPLL4 M4 divider appears wrong. For most
OMAP3 family SoCs this is 16, but it is defined as 32, which is maybe
only valid for omap36xx. To avoid any overflows in trying to write this
register, set the max to 16 for all omap3 family, except omap36xx. For
omap36xx the maximum is set to 31, as it appears value 32 is not working
properly.

Cleanup couple of TI divider clock internal APIs. These currently pass
huge amount of parameters, which makes it difficult to track what is
going on. Abstract most of these under struct clk_omap_div which gets
passed over the APIs.

Works for me. This also needs the change to dss.c to change the max from 
32 to 31. I'll send a patch for that separately.

Thank you!  This works for me.

Tomi,

Do you want me to push a patch to remove the
CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK hack once these patches have been
posted?  It seems like the divider fix eliminates the need for this
hack.

No, the point of OMAP2_DSS_MIN_FCK_PER_PCK was never to work around 
divider bugs. It's for scaling.
