[PATCH 00/15] drm/i915: Fix 830M/ns2501 for real, well almost

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Since the 830M dragon popped up again, I figured I'd dig out my old patches
that try to fix it.

I ended up reworking the primary plane code a bit also to eliminate the
DSPCNTR/DSPADDR RMW accesses since those are dangerous on 830M. But I think
the end result is more in line where we want to go anyway with the primary
planes anyway.

This has been tested on my Lifebook S6010 and this is the first time two
displays work reliably on this thing. Additionally we still need the minimum
watermark fix, for now I just used a hack (didn't include it here).
The only thing that doesn't work is suspend to ram. It suspends but won't
wake up, but that happens w/o i915 also so I can't take the blame for that.

I pushed the lot to [1] and the watermark hack is included there as well.

[PATCH 01/15] drm/i915: Use named initializers for gmch wm params

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Using names initializers when filling out the watermark structs
saves you from having go look up the struct definition every
single time.

[PATCH 02/15] drm/i915: Fix gen2 planes B and C max watermark value

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The max watermark value for gen2 planes B and C is 0x1f, instead of
the 0x3f that plane A uses.

Also check against the max even if the pipe is disabled since the
FIFO size exceeds the plane B and C max watermark value.

[PATCH 03/15] drm/i915: Don't get hw state from DVO chip unless DVO is enabled

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Certain DVO chips (ns2501 for example) don't like to be accessed unless
the PLL is running. Simply skip the DVO get_hw_state if the DVO port

To more closely match the IEGD ns2501 driver behaviour, call the
mode_set hook while the DVO port is still disabled, then enable the DVO

[PATCH 08/15] drm/i915: Rewrite ns2501 driver a bit

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Try to use the same programming sequence as used by the IEGD driver.

Also shovel the magic register values into a big static const array.

The register values are actually the based on what the BIOS programs
on the Fujitsu-Siemens Lifebook S6010. IEGD seemed to have hardcoded
register values (which also enabled the scaler for 1024x768 mode).
However those didn't actually work so well on the S6010. Possibly the
pipe timings that got used didn't match the ns2501 configuration.

[PATCH 09/15] drm/i915: Ignore VBT int_crt_support on 830M

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

My Fujitsu-Siemens Lifebook S6010 definitely has a VGA connector, but
the VBT says different. Ignore the VBT for 830M since it seems such
old machines would generally have a VGA connector.

This is a regression caused by:
 commit 9c2a03c2a194c086949f25d332937ac8dc4d9f7e
 Author: Jesse Barnes <jbarnes@virtuousgeek.org>
 Date:   Fri Apr 4 16:12:07 2014 -0700

    drm/i915: use VBT to determine whether to enumerate the VGA port

While at it refactor the code a bit to be more pleasing to the eye.

[PATCH 10/15] drm/i915: Fix DVO 2x clock enable on 830M

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The spec says:
"For the correct operation of the muxed DVO pins (GDEVSELB/ I2Cdata,
GIRDBY/I2CClk) and (GFRAMEB/DVI_Data, GTRDYB/DVI_Clk): Bit 31
(DPLL VCO Enable) and Bit 30 (2X Clock Enable) must be set to “1” in
both the DPLL A Control Register (06014h-06017h) and DPLL B Control
Register (06018h-0601Bh)."

The pipe A and B force quirks take care of DPLL_VCO_ENABLE, so we
just need a bit of special care to handle DPLL_DVO_2X_MODE.

[PATCH 12/15] drm/i915: Add pipe B force quirk for 830M

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

830M has problems when some of the pipes are disabled. Namely if a
plane, DVO port etc. is currently assigned to a disabled pipe, it
can't moved to the other pipe until the current pipe is also enabled.
To keep things simple just leave both pipes running all the time.

Ideally I think should turn the pipes off if neither is active, and
when either becomes active we enable both. But that would reuquire
proper atomic modeset support, and probably a bit of extra care in
the order things get enabled.

[PATCH 13/15] drm/i915: Eliminate rmw from .update_primary_plane()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Move the entire DSPCNTR register setup into the .update_primary_plane()
functions. That's where it belongs anyway and it'll also help 830M which
has the extra problem that plane registers reads will return the value
latched at the last vblank, not the value that was last written.

Also move DSPPOS and DSPSIZE setup there.

[PATCH 14/15] drm/i915: Call .update_primary_plane in intel_{enable, disable}_primary_hw_plane()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Make the intel_{enable,disable}_primary_hw_plane() simply call
.update_primary_plane(), thus eliminating the rmw from these functions
which should help the poor old 830M.

Now we can also remove the .update_primary_plane() from the
.crtc_enable() hooks.

This also has the nice benefit of making primary planes a bit closer to
the way we handle sprite planes during modesets.

[PATCH 15/15] drm/i915: Check pixel clock in ns2501 mode_valid hook

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The vbt on my Fujitsu-Siemens Lifebook S6010 provides two 800x600 modes,
60Hz and 56Hz. The magic register values we have correspond to the 60Hz
mode, and as I don't know how one would trick the VGA BIOS to set up
the 56Hz mode we can't get the magic values for the orther mode. So
when checking whether a mode is valid also check the pixel clock so that
we filter out the 56Hz variant.

Thanks for the patch and for all the work, unfortunately it does not 
quite work as presented. I applied the patch correctly to 
drm-intel-nightly, and it compiles fine.

However, the following issues exist:

*) If you boot with the kernel parameter vga=792 (i.e. the same console 
resolutions as initiated by KMS) the system just hangs with a black 
screen. Booting aborts, nothing happens.

*) Watermark settings are *still* not correct. *SIGH*, *sigh*

intel_reg_read 0x20d8
0x20D8 : 0x11F0104

This is a watermark level of 4. As I said multiple times, the watermark 
register needs to be *AT LEAST* eight (in numbers, 8) to have a stable 
display. It is stable between 8 and 32.

To reproduce, use a panning display with xrandr:

xrandr --output DVI1 --mode 1024x768 --panning 2048x1536

then scroll, and see the display flicker.

Folks, I really appreciate all your effort, but I would be really happy 
if my comments on the wrong watermarks wouldn't be continuously ignored. 
I submitted patches, twice, thrice... all went into the trash.

Greetings,
	Thomas

Bug reports on 830MG patches (thanks, but more trouble)

[Thomas Richter]

Update on the 830MG Updates:

As Ville already said, resume from "suspend-to-ram" is broken. No 
surprise, old broken bios. However, there is a big difference between 
the kernel with the pipe-A quirk disabled, and the one with pipe-a and 
pipe-b quirks enabled: If resumed without the quirk, the display is 
dead, but you can at least re-initiate it with vbetool post, then 
restart the X server. So at least, the kernel is working.

With the pipe A quirk enabled, something dies immediately when 
attempting to resume from suspend. The machine is completely 
unresponsive, also not reachable over the network. The kernel dies away. 
This is *probably* related to the dying kernel when booting with vga=792 
(or vga=791 or vga=790, all cause the same problem, no working machine.)

The code changes here look good to me.  You may want to reword/clarify
in the commit message exactly what "move entire register setup" means
since I didn't really know what you meant by that phrase until I looked
at the code and realized you were talking about starting to build the
new value for DSPCNTR which had previously started in *_crtc_enable().  

Looking at these *_update_primary_plane() functions makes me wonder
whether it might help future review if we were to add another patch for
these functions that reorders the bit setting to match the order they
appear in the docs.  Maybe also drop in a code comment in for each of
the bits that are described in the PRM, but that we're purposely just
leaving to a default value of 0 (180 rotation, async update, etc.) so
that it's clear to the reader that we expect the implicit assignment of
0 rather than overlooking overlooking we should have been programming.

Anyway, the code changes here look good, so with or without my
suggestions this is

This is because intel_crtc_enable_planes() ->
intel_enable_primary_hw_plane() takes care of it for us, right?  Can you
clarify that in the message?  That wasn't immediately obvious from the
context visible in the diff.

Reviewed-by: Matt Roper <matthew.d.roper@intel.com>

On a somewhat related note, is there any reason not to call
.update_primary_plane() at the end of the various sprite update
functions in intel_sprite.c instead of calling
intel_update_primary_plane() and intel_flush_primary_plane()?  I find
the name similarity between intel_update_primary_plane() and
.update_primary_plane() confusing and it looks like we might be able to
consolidate a bit there unless I'm overlooking something.

I simply decided to leave the sprite code alone for now. Should probably
just call the .update_primary_plane hook there as well. It doesn't seem
too heavy to really compromise the atomic vblank evade thing. Though
at some point we should really start building up the plane_config thing
and then we should be able to minimize the amont of stuff we do in
that section.

For me resume gets stuck even w/o i915. So something is different
clearly between our machines. Might be some driver, or might the BIOS.
Do you have the latest BIOS on that thing?

I must admit I didn't try the vga= options. I'll give them a go and see
what happens.

Well we could have 2 match structs for dvoc and dvob. I guess on Thomas'
X30 it is actually on dvob, otherwise he wouldn't have picked that one ...

Well I think now's the time to move those checks into intel_crt_init. We
don't care at all whether we have a vga port, and imo that way it's
cleaner. eDP/mipi dsi and similar checks are also done in the _init
functions.

Yup, I flashed the bios last week with version 1.07, the latest I could 
find on the Fujitsu pages. It was 1.06 before, though I did not observe 
any difference between 1.06 and 1.07 with respect to the broken resume 
operation.

There is a difference between "freeze" and "freeze". Yes, w/o the pipe-A 
quirk, the screen goes black, but you can reach it over the network, and 
you can even type into the console and submit the video restart from 
there. So, it's not frozen, only the display is "off", though it looks 
the same for the untrained eye.

Maybe the bios configuration between yours and mine is different?

Please do. I have narrowed it down to the case where text mode vs. 
graphics mode makes a difference. That is, a frame buffer console alone 
is sufficient for the machine to get stuck when loading i915.

Ok, I'll try tonite to clone from your repository instead of 
intel-drm-nightly and report back. But if you have a patch concerning 
the watermark that works and is *accepted* into intel-drm-next, I would 
be thankful indeed. This is really annoying...

(It's not that it is hard to work around the watermark issue....)

So long,

[PATCH v2 09/15] drm/i915: Ignore VBT int_crt_support on 830M

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

My Fujitsu-Siemens Lifebook S6010 definitely has a VGA connector, but
the VBT says different. Ignore the VBT for 830M since it seems such
old machines would generally have a VGA connector.

This is a regression caused by:

[PATCH v2 13/15] drm/i915: Eliminate rmw from .update_primary_plane()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Move the entire DSPCNTR register setup into the .update_primary_plane()
functions. That's where it belongs anyway and it'll also help 830M which
has the extra problem that plane registers reads will return the value
latched at the last vblank, not the value that was last written.

Also move DSPPOS and DSPSIZE setup there.

v2: Don't move variable initialization to avoid churn later

[PATCH v2 14/15] drm/i915: Call .update_primary_plane in intel_{enable, disable}_primary_hw_plane()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Make the intel_{enable,disable}_primary_hw_plane() simply call
.update_primary_plane(), thus eliminating the rmw from these functions
which should help the poor old 830M.

Now we can also remove the .update_primary_plane() from the
.crtc_enable() hooks because we end up calling it via
intel_crtc_enable_planes()->intel_enable_primary_hw_plane().

This also has the nice benefit of making primary planes a bit closer to
the way we handle sprite planes during modesets.

v2: Just write 0 to DSPCNTR and DSPSURF/DSPADDR if the plane is (to be)
    disabled. Quicker, and more importantly avoids an oops when fb==NULL
    due to BIOS fb takeover failure.
    Pimp the commit message a bit (Matt)

[PATCH 16/15] drm/i915: Pass intel_crtc to intel_disable_pipe() and intel_wait_for_pipe_off()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Just pass the intel_crtc around instead of dev_priv+pipe.

Also make intel_wait_for_pipe_off() static since it's only used in
intel_display.c.

[PATCH 17/15] drm/i915: Disable double wide even when leaving the pipe on

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Disable double wide even if the pipe quirk compels us to leave the
pipe running. Double wide has certain implications for the plane
assignments so best keep it off.

Also helps resuming from S3 on the Fujitsu-Siemens Lifebook S6010
when double wide was enabled prior to suspend.

We do leave the pixel clock ticking at the original rate which would
require double wide to be enabled. But since the planes are all disabled
I'm hoping that the overly fast clock won't cause any problems. Seems
to be fine so far.

[PATCH 18/15] drm/i915: Preserve VGACNTR bits from the BIOS

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

My Fujistsu-Siemens Lifebook S6010 doesn't like to resume from
S3 unless VGACNTR has been restore to the original value. The BIOS
value in this case was 0x0124008E. Setting the "VGA disable" bit
doesn't interfere with the S3 resume fortunately.

OK, so I posted a few revised patches, and three new ones. With these my
S6010 can resume from S3 if and only if:
1. pass acpi_sleep=s3_bios to the kernel command line
2. unload i915 before suspending

1. I guess is expected since you also had to use vbetool to post the
GPU. Having the kernel do it is better since then you can't clobber the
state while i915 is already doing stuff.

2. is more strange. I assume there must be some magic difference between
our suspend vs. unload and/or resume vs. init codepaths that cause problems.
Although the fact that you don't need to do it makes it even stranger. I
tried to use the pm_trace facility a bit bit didn't really get anywhere.
So given that this thing is a dinosaur I think I'll now leave it and either
let someone else figure it out or come back to it when I'm really bored.
Otherwise the machine works pretty decently for me now.

I think the reason why killing the pipe A quirk might have made a 
difference for you was the fact that i915 no longer registered the VGA
port and so the DVO port always stayed assigned to pipe A. But if you'd
just applied the "ignore VBT" patch and gotten the VGA port back, things
would have failed again rather nicely especially when trying to use both
pipes.

I pushed the new patches to [1] and I still included the watermark hack,
and there's an additional locking fix you'll want as well.

[1] git://gitorious.org/vsyrjala/linux.git alm_fixes5

So apart from the remaining S3 resume mystery the minimum watermark
problem is still to be solved. I think Chris's idea of converting
the .default_wm parameter to a minimum watermark level is sane. But in
order to do that I think we should do these things:
- s/.default_wm/.min_wm/
- Replace the current .default_wm values with "burst size" (maybe with +1)
  Some of the current .default_wm values make absolutely no sense as a
  minimum value (pnv at least has 0x3f there!)
- Someone should maybe figure out why we use a larger burst size on
  845/865 than on the other platforms

Ok, great.

As said, only with the pipe a quirk removed... I had "plug & play os" 
enabled, and the "security screen on resume" disabled.

This is as good as I had it without the pipe A quirk as well. Unloading 
i915 worked as well: I had to post the GPU, then either reload i915 or 
restart X.

Yes.

Likely.

Not exactly, see above. Reloading i915 works as well, but otherwise you 
had to stop X, then restart X, then re-set the resolution to ensure that 
everything is configured correctly.

resume from suspend is not really much an issue. suspend to disk works 
fine, and there is likely a bios problem.

Did you notice that intel_reg_snapshot just dies when you try? Also, if 
you check the bootlogs, some I/O regions seem to overlay. Probably 
resume tries to reload the same I/O addresses intel_reg_snapshot tries 
to save? vbetool vbestate save also hangs the machine...

> Otherwise the machine works pretty decently for me now.

Yes, with the watermark settings in place - from your repository - 
everything is as good as it gets.

Could you please create a patch for intel_calculate_wm() that adjusts 
wm_size, probably depending on GEN2?

That is what I pulled probably two hours ago. It still has the issue 
with dying with vga=792 as boot parameter. When did you submit?

I guess I do have a couple of additional intel based machines here if 
that is of help. A 945 based board is here, and some later machines.

Hmm. I don't think I tried the pnp os option. I'll give it a go next

Just restarting X has some risk in case the vbetool POST clobbered some
state that i915 only sets up at init or resume.

Daniel was threatening to resurrect his watermark branch. But I don't
really see a problem with going with a temporary fix in the meantime
maybe even only for 830.

I pushed just before sending the email. I think what you have is
alm_fixes4, which indeed did blow up with vga= for me as well.
alm_fixes5 should fare better.

Sure, but we can't probe the DVO port so we need to use VBT/DMI/something
to figure out which one to pick. In theory VBT should have information.

[PATCH v2 17/15] drm/i915: Disable double wide even when leaving the pipe on

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Disable double wide even if the pipe quirk compels us to leave the
pipe running. Double wide has certain implications for the plane
assignments so best keep it off.

Also helps resuming from S3 on the Fujitsu-Siemens Lifebook S6010
when double wide was enabled prior to suspend.

We do leave the pixel clock ticking at the original rate which would
require double wide to be enabled. But since the planes are all disabled
I'm hoping that the overly fast clock won't cause any problems. Seems
to be fine so far.

v2: Disable double wide also when turning the pipe off

I guess someone needs to dig out vbt docs then and figure out what
we've missed. Could be that the vga option is fairly new.

Jesse/Ben can you please look into that?

Yeah the meaning has changed over time, I'm trying to get the info from

Positive feedback on this one: WIth this patch, I can finally set VGA 
and internal display (DVI) to independent resolutions.

Thanks!

[Patch] Add minimum watermark level for I830

[Thomas Richter]

[-- Attachment #1: Type: text/plain, Size: 661 bytes --]

Dear Daniel, dear intel experts,

please find a minimally-invasive patch to add a minimum watermark level 
to the current watermark logic. This fixes the flickering and video 
overlay crashes on 830M(G) chipsets. Note that this patch does not alter 
the watermark algorithm on any other family of the intel chipsets.

Greetings,
	Thomas

PS: What I do not understand about the current logic is that there is a 
"default watermark" level if the computed watermark is below zero, 
though computed watermarks can well drop below this default. The 
appended patch still allows that to be backwards compatible, though this 
construction sounds pretty weird to me.

[PATCH] Check for a min level when computing the watermark.

[Thomas Richter]

[-- Attachment #1: Type: text/plain, Size: 635 bytes --]

Dear intel experts,

the attached patch is a minimally invasive modification of the watermark 
computation for the 830GM chipset graphics. It adds a minimum watermark 
level to test against. The minimum value is zero for all other families 
of the intel chipset graphics, thus causing no change there.

What is still strange is that the default watermark level is only used 
if the watermark level computation returns a value below zero, though 
values *below* the default value are acceptable as long as the are above 
or equal to zero. Anyhow, I keep it like this for the time being to 
avoid breaking anything.

Greetings,
	Thomas

Deadlock in intel_enable_pipe_a()

[Thomas Richter]

Hi Ville, hi Daniel, dear intel experts,

just went through the problem I send around, and I guess I understand 
now what happens here. The reason *why* resume fails is that there is a 
deadlock situation in intel_display.c:

*) loading the module calls intel_modeset_init()
*) intel_modeset_init() calls intel_modeset_setup_hw_state(), but 
protects access to it with a global lock.
*) intel_modeset_setup_hw_state() calls intel_sanitize_crtc()
*) intel_sanitize_crtc() finds that the pipe-a quirk is enabled and 
calls intel_enable_pipe_a()
*) intel_enable_pipe_a() calls intel_release_load_detect_pipe(), however 
not using the same mutex context as the caller (intel_modeset_init()).
*) intel_release_load_detect_pipe() again gets the mutex of the crtc.

Unfortunately, at this time, the caller (intel_modeset_init()) had 
already everything locked.

Needless to say, this deadlocks and blocks the kernel completely, 
causing the problem I found above.

To verify my hypothesis, I removed the locks in 
intel_release_load_detect_pipe(), (obviously risking race conditions, 
but never mind for the test).

The result is that the machine is responsive after the resume. It still 
does not show a display (apparently, intel_sanitize_crtc() is 
insufficient and does not sanitize enough), but at least one can 
force-enable it again.

Thus, two bugs:

1) attempting to lock the same lock twice, nested, causing a deadlock. 
The pipe A quirk is not working correctly by requiring a call into a 
method that requires a lock that is already held.

2) not sanitizing the chipset sufficiently, still keeping the display 
black. (This, being, of course a side effect of the buggy bios).

Hope this helps!

Thomas

[PATCH] drm/i915: Avoid double mutex lock applying pipe A quirk during sanitize_crtc()

[Chris Wilson]

Thomas found that his machine would deadlock reloading the i915.ko
module after resume. He identified that this was caused by the
reacquisition of the connection mutex inside intel_enable_pipe_a()
during the CRTC sanitization routine. This will only affect machines
that quirk PIPE A, i.e. the original 830m chipsets.

This patch move the locking into a wrapper function so that
intel_enable_pipe_a() can bypass the locking knowing that it already
holds the correct locks.

It can still try to grab crtc->mutex twice. Looks like Danial undid my
fix to not take all the modeset locks around
intel_modeset_setup_hw_state().

Oh well, I only considered the santize_crtc path as I thought we would
have caught the modeset sequence deadlocking earlier.

Anyway, the locking is in flux due to the conversion to ww_mutex.
Have fun ;-)

Partial success - Fixing resume from s2ram on S6010

[Thomas Richter]

[-- Attachment #1: Type: text/plain, Size: 1908 bytes --]

Hi Ville, dear intel experts,

without the deadlock in i915, I had at least a partial success in 
restoring the video on the Fujitsu S6010.
Apparently, the bios does not re-initialize the 830MG registers, nor the 
registers of the ns2501 DVO.
Instead, the 830MG is configured in a 640x480 mode (no matter what the 
suspend mode was) and
the DVO is configured in a DPMS off state (no matter what the mode was 
before the suspend).

The attached script, to be placed in /etc/pm/sleep.d/99video will force 
correct values back into the registers
and thus restore the display. Partially. Trouble still is that the 
restored screen has some type of "hick-up" by
moving left or right by a couple of pixels (probably exactly by one 
tile, I did not measure). Interestingly,
a dump of the DVO and 830MG registers did not reveal any significant 
difference before and after the restore,
so it is still unclear why that hick-up appears.

Anyhow - it seems that $OTHER_OS has a completely different strategy for 
resume than Linux. $OTHER_OS seems
to simply re-load the video registers for the currently active mode, 
ignoring the current state of the hardware.
The i915 kernel module instead seems to try to interpret the current 
register set to a video mode, and then
restores its state from the state of the hardware. It seems to me that 
this is a less than ideal approach, and
it would be better keep a copy of the registers how they should be 
during suspend, and restore them in
the kernel module to the correct video mode on resume, ignoring whatever 
the bios left there.

Do kernel modules like the i915 or the dvo_ns2501 offer some kind of 
hook that is called by the kernel when
the machine is suspended and resumed? If so, this would be extremely 
helpful and would allow a much safer
suspend/resume operation than currently possible with the mode-detect 
guess i915 attempts to do.

Thanks,
     Thomas

No, we do restore the mode you were using before suspend.

Are you still using vbetool? That would explain why things go bad since
vbetool will clobber whatever i915 already did.

No, vbetool is out of the equation (see the script attached to the 
previous post). However, I dumped the 830MG register set
and the ns2501 DVO set before and after the suspend, and they are pretty 
different. As said, the 830 is configured
to use a 640x480 mode (instead of the 1024x786 mode) and the DVO is off.

Maybe the kernel tries to mode-detect the connected monitor, and this 
fails because the PLLs are not yet
configured correctly? Note that the ns2501 requires a correctly 
configured DVO to be able to respond on
the i2c bus. If so, mode-detection requires configuring the PLLs to 
*some* useful mode before attempting
to detect anything, otherwise the DVO just plays "dead".

Greetings,
     Thomas

So now you're using acpi_sleep=s3_bios, or nothing?

Boot with drm.debug=0xe grab the dmesg after the resume and let's see
if there is something fishy happening.

Tried with acpi_sleep=s3 and nothing, makes no difference.

Ok, here we go:

Note that the kernel finds that all outputs are disabled, then loads a 
640x480 mode. All pipes and crtcs are disabled, too.

Re: Partial success - Fixing resume from s2ram on S6010

Ok, tried now with acpi_sleep=s3. Unfortunately, this hangs the machine 
completely during resume, I cannot even ping it.

Then, I tried the same trick again, namely unloading the i915 module 
before the resume, reloading it after the resume. This worked 
flawlessly, display came back without requiring any quirks, even with 
the state the bios left the hardware in.

Note again that this is different for the resume from acpi_sleep=s3 or 
'nothing', where I can restore the display (though the result is a hick-up).

If there is another deadlock in i915 (not unlikely) I cannot debug it 
this way, unfortunately.

Unfortunately, the S6010 does not have a serial port to redirect the 
console to. I can only use the netconsole, though this reveals nothing. 
Probably the deadlock happens before the is enabled.

Greetings,

Re: Partial success - Fixing resume from s2ram on S6010

[Thomas Richter]

Hi Ville, dear Intel experts,

more on the partial resume from suspend for the S6010. It seems that the 
culprit is really the lack of a proper
initialization of the DVO. The minimum sequence to restore the display 
does not require to modify the 830 registers
directly, but rather needs to setup the DVO.

xrandr --output DVI1 --mode 640x480
# without this, access to the DVO is blocked, thus
# all the following fails. The above initializes the
# PLLs such that the DVO can be accessed.

modprobe i2c-hid
modprobe i2c-algo-bit
modprobe i2c-dev
modprobe i2c-scmi
modprobe i2c-i801
modprobe i2c-ismt
modprobe i2c-gpio
modprobe i2c-piix4
modprobe i2c-isch
modprobe i2c-mux
modprobe i2c-core

#
# Only the following two are required.
i2cset -y 5 0x38 0x34 0x02
i2cset -y 5 0x38 0x35 0x7f

# This restores the old resolution.
xrandr --output DVI1 --mode 1024x768

Thus, it really seems that the culprit is here that the resume operation 
does
not provide access to the DVO correctly.

Greetings,

[PATCH] drm/i915: Init important ns2501 registers

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

In my earlier rewrite I missed a few important registers. Thomas Richter
noticed that they're needed to make his machine resume correctly.

Looks like IEGD does a one time init of these three registers. We don't
have a good one time init place in the ns2501 driver, so let's just
stick them into the .mode_set() hook and see if that helps things along.

Thanks, this *almost* works, much better than before. Now I only need to 
switch the console
forth and back to get a display. However, I get a pretty unstable 
display on the console, and
a *sometimes* unstable display on the X display. From the way it looks, 
I would guess that
the synchronization between the display and the PLL is not quite right. 
Which is stunning since
the 830M seems to be configured correctly.

Greetings,
     Thomas

Hi Ville,

thanks for the latest patch. As said, the screen did not come back quite 
correctly. I checked the register values
again, and I am sorry to say that I was wrong - register values do 
differ. Apparently, the code configures now
the wrong pipe to generate output to the DVO and thus the DVO does not 
seem to synchronize correctly
anymore. Please find the two register dumps attached.

Greetings,
     Thomas

Hm, I didn't find anything in git logs and we've had places where we used
modeset_lock_all since a long time. And I don't see how Chris' patch
wouldn't address this here. Can you please explain?

It's just diff. The change was to rejig the braces to remove the
duplicated unlock + return.

I added the modeset_all locking here:
 commit 027476642811f8559cbe00ef6cc54db230e48a20

    drm/i915: Take modeset locks around intel_modeset_setup_hw_state()

and then had to reduce it to just the mode_config.mutex precisely due to
the pipe A quirk here:

Hm, indeed missed this since we have a bunch of other places that still do
the full modeset_lock_all, but probably not possible to hit the pipe A
quirk there. The ww mutex code makes this a bit more annoying so I guess
Chris' patch with having a lock-less pipe A quirk is the way to go.

But that one needs to be updated for latest drm-next/-nightly.

Either pipe can drive DVO just fine. Looks like it's using pipe A in
your register dump, and all the registers look fine to me. Well, DPLL B
VCO enable is off since we don't currently have a mechanism to kick pipe
B into action during resume/load. In theory that would need to be enabled
as well.

Can you see if a simple 'intel_reg_write 0x6018 0xc08b0000' fixes the
problem?

And if not, I'd like to see a diff of register dumps between working and
non working setups.

Nope. I created a little script that wrote the previous data back into 
the chipset, but that did not cure the problem. The only register I 
could not write to was CACHEMODE (IIRC, this was the name intel_reg_dump 
gave). The plane pointers and cursor pointers were different, too, but 
that should not be critical.

I afraid the S6010 is out of reach for the next three weeks, but I 
should have a complete register dump attached to my previous mail from 
yesterday night (or this morning, to be precise).

I can now try on the R31, but I don't remember having seen anything like 
it there. It does *not* look like the flickering of the misaligned 
watermark registers - on the console it really looks like bad HSYNC on a 
TV (tearing across horizontal lines, and massive misalignments of the 
very first lines of the screen). Within X, it causes the screen to jump 
to the right by about 64(?)128(?) pixels. The problem does not disappear 
by using a different resolution or restarting X. It remains permanent 
until the next boot.

i830GM on IBM R31 works with alm_fixes5 repository

[Thomas Richter]

Hi Ville,

thanks again for your alm_fixes5 branch. Just installed it on the old 
R31 - this seems to work fine. The external monitor works
(unlike with intel_drm_nightly, which is broken), and watermarks are 
also setup correctly. Booting works correctly, boot console
is setup correctly.

Suspend to RAM does not work, but this does not seem to be the fault of 
the i915 and drm modules. Even with almost all modules
unloaded, the machine hangs when trying to resume. The suspend2ram tests 
all work fine (i.e. freezing tasks, devices...), but as
soon as I use a real suspend (no testing), the machine does not wake up. 
The s3_sleep kernel parameter is not able to work around
this, i.e. there is no combination which makes this working. The BIOS is 
the latest version I could find (ancient, still) but no avail.

Machine remains completely unresponsive, no network, no mouse, no 
keyboard, no video, no sound. The pm-suspend rtc debugging
tricks do not reveal in which kernel module the machine hangs, nothing 
seems to match the recorded hash. The problem must appear
pretty early in the call-chain.

Anyhow, this is not i915 related as it seems, so nothing to fix here. 
I'll try to find out a bit more on this if I can.

Greetings,
     Thomas

Going through some old patches I spotted this one. It no longer applies,
and the crt presence check has been changes. Do those changes fix the
issue here as well?
