Hi Daniel, dear intel-experts,
again I had the chance to test the latest intel-drm-nightly of the
3.14.0 kernel on the Siemens S6010 with its dreadful nso2501 DVO.
Unfortunately, there are still a couple of issues here, and I also want
to report on some progress and some workarounds.
1) Panning on the i830 still flickers, reproducible both on the Fujitsu
S6010 and the IBM R31. The problem is all again the same, namely that
the watermark is set too low (or too high, if you like). The
intel_calculate_wm() function in intel_pm.c returns a watermark level of
0 for the nominal display configuration (1024x768), which is just too
high. The maximum allowable watermark should be 8. I already submitted a
patch for this problem, though unfortunately, it had not been accepted.
Folks, could we *please* fix this issue? It is really trivial, and it
really causes crashes if a video overlay is on the panning screen -
thus, this is more than just a cosmetic fix.
2) Pipe_A quirk: Actually, this is not required or needed on the S6010
nor on the R31. In fact, it breaks more than it fixes. The problem is
that the pipe A quirk causes the boot console to be misaligned with the
screen, or to be completely blank. This is undesirable if you boot into
maintenance mode (i.e. without an X interface). Just disabling the quirk
avoids this problem in a wonderful way.
3) Suspend to RAM: Whether with or without the quirk, s2ram is
non-functioning, but *almost* functioning. The problem on the S6010 is
again the ns2501. Unfortunately, I do not know which of the intel
functions are called on resume in which order, but it seems to me that
the DVO is reprogrammed *before* the pipes and plls are reconfigured.
Unfortunately, this cannot work with the ns2501. It requires proper PLL
configuration for even receiving commands on the i2c bus, otherwise it
locks up. Thus, it would be helpful to know which functions the intel
driver runs through for resuming the display, maybe I would have then
the chance to dig more into this.
Everything else in the resume works, and one can an "almost working"
resume by reprogramming the PLLs on resume by the intel-gpu-tools and
calling a small script on resume:
intel_reg_write 0x02120 0x0
intel_reg_write 0x61100 0x00000c00
intel_reg_write 0x61160 0x10004084
intel_reg_write 0x6101c 0x027f01df
intel_reg_write 0x61000 0x031f027f
intel_reg_write 0x61004 0x03170287
intel_reg_write 0x61008 0x02ef028f
intel_reg_write 0x6100c 0x020c01df
intel_reg_write 0x61010 0x020401e7
intel_reg_write 0x61014 0x01eb01e9
intel_reg_write 0x71180 0x01000000
intel_reg_write 0x70188 0x00001000
intel_reg_write 0x20d8 0x10E0108
intel_reg_write 0x20dc 0x102
intel_reg_write 0x61120 0x0
intel_reg_write 0x6014 0xD0820000
intel_reg_write 0x6018 0x0
intel_reg_write 0x61140 0x80004084
intel_reg_write 0x61160 0x90004084
This will give back a workable display, though with a couple of
hick-ups. That is, on suspend, switch to the console (here also at
1024x768 resolution), then suspend. On resume, run the above script,
then switch back to X.
What is interesting is that the resume functionality seems to program
the pipes differently. Resume tries to feed the display through pipe A,
however, the DVO for the internal display is on pipe B. Here is the
register dump before and after the resume:

INST_PM: 0x00000000
pipe A dot 65000 n 4 m1 21 m2 13 p1 4 p2 4
pipe B dot 327000 n 2 m1 18 m2 7 p1 2 p2 2
Note that this is already with the pipe A quirk removed. Apparently,
something is wrong in the driver when trying to re-establishing the
display. Everything else works on resume, i.e. sound, wifi, mouse,...
are all in good shape.
Note that post-ing the display through the bios (i.e. vbetool post) is
*not* a good idea as it leaves the GPU in a useless state. Also, setting
the vbemode through the bios (i.e. vbetool vbemode set 16664) does not
work as desired. That is, the usual candidates for establishing the
display have been tried and are non-working.
Hope this helps for narrowing the problem.
Thanks,
Thomas
