 I tried to work out how to get optimus to work. After trying several
 different sets of instructions I never found a working configuration
 and put it aside. I never used to use opengl but lately my pcb
 software has adopted it so my needs changed.

 I will get back to you with more results on this matter after I get
 the newer kernel up.

 Often but not always the case -- the clock speed is whatever the VBIOS
 leaves it in. For kepler, that is usually the lowest setting.

 much hotter in linux than macos? I turned off the intel graphics and
 the cpu clock is set to the lowest available speed.

 You should instead turn off the nvidia graphics and run off intel --
 intel is much less power-hungry than nvidia, even at the lowest
 clocks. If it's an optimus setup, the nvidia gpu should automatically
 power off until needed (either because some display is connected to
 it, or for offloading).


 How do I get a display of the GPU clocking speeds?

 You should see it in dmesg... look for CLK lines. The ones with -- (or
 AC/DC) will show the current setting. Or boot with nouveau.pstate=1
 and you should have a /sys/class/drm/card*/device/pstate file.

 Is it still an issue with 3.19? I tried Xonotic and video streaming with
 Firefox but was unable to trigger those isses using Nouveau's HEAD
 (currently at
 http://cgit.freedesktop.org/~darktama/nouveau/commit/
 ?id=e616d549c78c27b6b4d4da25a2369b32bb2a99db).

I'll run it up the flagpole and see who salutes… Out of interest how much of
current 'nouveau' HEAD is in the mainline kernel at present?

(I realise I meant to try a git bisect to possibly locate the needed patches, I
apologise for not getting to that.)

I guess you're trying to compile Ben's repository
(http://cgit.freedesktop.org/~darktama/nouveau/)? If that's the case, it is an
out-of-tree repository, so you still need regular kernel sources.
To compile it, go to the drm/ directory and execute just a make - it will try
to find where the sources are for the kernel you're actually running, or you
can override this by setting the env variable LINUXDIR. This will only compile
the nouveau.ko module, which you will then find at drm/nouveau/nouveau.ko.

[Nouveau] [Bug 28095] X crash with PFIFO_CACHE_ERROR. (Nouveau on Riva TNT).

2015-02-14 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=28095

--- Comment #14 from Ilia Mirkin imir...@alum.mit.edu ---
So by the sounds of it, we broke the display stuff at some point between
pre-history (i.e. before nouveau was in mainline) and... now. I'm fairly sure
that it's a fairly self-contained problem -- my NV05 TNT2 M64 works fine (or at
least did recently, I think I last tested after 3.10 or so). Another user's
NV04 also worked OK on linux-3.9 (from bug 68854), although it was the Creative
Labs one. However he also had the resolution issue (maxing out at 1024x768).

You have one of the (infamous?) BMP v0 vbioses, may be interesting to attach it
to this bug, although I sincerely doubt that is the source of the issues
(before BMP v2 or so, we just ignore it entirely). Without nouveau loaded, you
can get it from /sys/kernel/debug/dri/0/vbios.rom .

The unfortunate reality here is that you are in posession of fairly unique
piece of hardware, and that (I believe) similar HW works fine. So... it's
something funny going on. 

You might try booting with

nouveau.debug=debug drm.debug=14

and capturing the kernel messages from that. Perhaps something interesting will
come up.

Ahh right, I understood it was a fork of the kernel tree and so added it as a
remote in my git repository, pulled it in and tried to build it as such.

So I've now built kernel 3.19 (commit
bfa76d49576599a4b9f9b7a71f23d73d6dcff735).  I shall reboot and test with that
in its stock configuration.

Then if I get problems, I'll try out the above git tree, building the
nouveau.ko module out-of-tree, install it, do another reboot and see if the
problem persists.

 You should instead turn off the nvidia graphics and run off intel --
 intel is much less power-hungry than nvidia, even at the lowest

 power off until needed (either because some display is connected to
 it, or for offloading).

 You should see it in dmesg... look for CLK lines. The ones with -- (or

 Because I am on a macbook the VBIOS might be wonky.

 I tried turning off nVidia and using intel. The result was a blank
 screen. I know other people had the same bug which was something to do
 with reprobing lvds?! I saw patches go by and every time I tried one
 the results were the same. fail. I was actually about to post a bug
 report to the intel (i915) people about it.

 I tried to work out how to get optimus to work. After trying several
 different sets of instructions I never found a working configuration
 and put it aside. I never used to use opengl but lately my pcb
 software has adopted it so my needs changed.

 I will get back to you with more results on this matter after I get
 the newer kernel up.

 I have a side question which may be the subject of a future second bug
 report. I have been lurking on the nouveau mailing list for some time.
 I understand from various posts that the nvidia gpu clock speed right
 now is set to the lowest possible setting. Why does my machine run so

 Often but not always the case -- the clock speed is whatever the VBIOS
 leaves it in. For kepler, that is usually the lowest setting.

 much hotter in linux than macos? I turned off the intel graphics and
 the cpu clock is set to the lowest available speed.

 You should instead turn off the nvidia graphics and run off intel --
 intel is much less power-hungry than nvidia, even at the lowest
 clocks. If it's an optimus setup, the nvidia gpu should automatically
 power off until needed (either because some display is connected to
 it, or for offloading).


 How do I get a display of the GPU clocking speeds?

 You should see it in dmesg... look for CLK lines. The ones with -- (or
 AC/DC) will show the current setting. Or boot with nouveau.pstate=1
 and you should have a /sys/class/drm/card*/device/pstate file.
