Regression DRM/i915/KMS: VGA connector unusable after 2.6.31-rc8-git1, DVI connector ok

Hi everybody!

During the release cycle of the 2.6.31-rc* kernels KMS started to work
on my computer.

Booting with a monitor attached to both the VAG and the DVI connectors,
kernel 2.6.31-rc8-git1
detects both monitors correctly and sets the native video mode.

Booting the same configuration with kernel 2.6.31-rc8-git2 ... -rc9-git1
gives a different result:
the DVI-attached monitor is still working perfectly, the VGA-attached
monitor does not detect a
valid video signal and switches off.

Hardware: AOpen i915GMm-hfs,  Pentium-M 1.86 MHz,  2GB RAM
The Aopen i915GMm-hfs is a  desktop board with a mobile Chipset:

00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML
Express Processor to DRAM Controller (rev 04)
00:02.0 VGA compatible controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 04)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 04)

Config: AGP/DRM/I915 all compiled into kernel, KMS enabled.

Log_Broken contains the result of "cat boot.msg | grep -i drm" of a boot
with 2.6.31-rc8-git2,
Log_OK contains the result of "cat boot.msg | grep -i drm" of a boot
with 2.6.31-rc8-git1

As a black monitor is not a nice gift I think this should be fixed
before the final release of 2.6.31.

cu,
 Knut

I had a similar problem between -rc8 and -rc9, and the patch here

http://marc.info/?l=linux-kernel&m=125239311508274&w=2

fixed it for me.

I just pushed out something that may fix it. It was reported to fix 
another situation that sounds _somewhat_ similar (ie VGA out on a mobile 
chipset)

It's commit 7c8460d: "drm/i915: fix mask bits setting", but it may take a 
few minutes to mirror out to the public machines, so if you don't see it 
yet, here's the patch if you want to try.

Zhenyu Wangs patch fixed the problem, and 2.6.31-rc9-git2 works again with
monitors attached to the VGA output. Thanks to all of you for the quick
reaction.

BTW: My reason to try kernel 2.6.31-* is to find a good replacement for
my current
outdated setup (kernel 2.6.22.6 with a vintage (2006) X Window System
Version 7.1.99.902).
I´m testing the current kernels and X.Org X Server 1.6.3, Release Date:
2009-7-31, with
intel module version = 2.8.0. (openSuSE 11.2 MS 6).

The old setup is a bit faster, and glx acceleration is much smoother:

- glxgears running on the old setup looks fine running on
  the old software, no matter what window size is used.

- glxgears running on the new setup looks almost fine with small
  windows, but is _very_ jerky running in a big window.

As the old X does not work with the new kernel, I cannot decide if the
kernel
or X is to blame.

Some other things I noticed. Have a look at the log:

What shall I think about that render error followed by "EIR stuck"?
Apparently it does not hurt, but it does appear on every boot.

What´s about that page table error? It´s also in every boot log,
and it seems that it does not hurt either.

In the boot log I  read "TV-12: set mode NTSC 480i 0". Well, I do
not use the TV out connector, but in the BIOS setup I selected
PAL and not NTSC. Why isn´t that detected and used?

Hmm. Doesn't old X work if you disable KMS? Either with "i915.modeset=0" 
or by just compiling it out?

Also, glxgears is usually not a good way to verify anything. At least some 
versions used to run the gears at the painting frame rate rather than some 
fixed rate, and so "jerky" or not depended not on how fast it was 
painting, but on whether the painting speed was some multiple of the 
screen refresh.

The FPS output from glxgears should mean something, although quite 
frankly, considering the simplicity of the thing, not a whole lot. I'd 
suggest using some somewhat more real test (I admit to having used 
"Extreme Tux Racer", which while not wonderful either is certainly better 
than glxgears ;^)

Linus is probably right here; old X assumes it completely owns the
hardware, so won't work very well if you have a KMS enabled i915
driver.  Loading i915 with modeset=0 should let you use the old
interfaces.

These two are related.  The BIOS is probably setting up a partially
bogus configuration.  Then when the i915 driver initializes we see the
errors.  We might be able to work around it by doing some extra
hardware work (disabling everything or scanning for bad addresses), but
I haven't had time to try that out yet.

You'll see lines like that whenever the kernel does load detection on
an output.  In this case it's trying to set a mode on the TV output
(which is always there, even if you don't have an exposed connector) to
see if anything is attached.  For load detection purposes I don't think
it matters if we use PAL or NTSC signaling; but please file a bug at
bugs.freedesktop.org if you find problems (see
http://www.intellinuxgraphics.org/how_to_report_bug.html for the sort
of info we're looking for).

It does work somehow, but very slow and jerky as long as DRI is
enabled in the kernel.

It´s not a a problem related to KMS. Allocation of tiled buffers fails with
that old X, although it worked with 2.6.22.6, that results in a massive
performance drop (more than 70 percent).

Jerky drawing can only be avoided if DRI is disabled in the kernel.
