[Bug 653714]

agpmode and modeset are not even remotely related I'm afraid. With 4.3
onward one should be using nouveau.config="NvAGP=0" as documented [1]

The report in question is (was?) about the gallium radeon driver -
r600g.

On the classic radeon/r200 front there was a regression caused by commit
779cabfc7d022de8b7b9bc7fdac0caffa8646c51 (which itself fixing some BE
issues, circa 11.0), which was resolved in 11.0.6 and 11.1.0. If things
are still off, then I'd suggest opening separate bug report and if
possible bisecting it down.

Nicely done. I hope that the problem does not end up a sheep in wolf's
clothing - i.e. somewhere else. Using gcc+bintutils, to compile a third
library, which links to another two compiler(ish) products... there are
so many things that can be happening in there.

Thank you for the great initiative :)

[Bug 1371636]

2014-09-29 Thread Emil-l-velikov
Building OpenCL works like a charm here. Can you try to establish which
(if any) of the following components is responsible - llvm, gcc (*cough*
4.9.2_alpha) binutils or clang.

I'm building it on Archlinux (llvm 3.5.0, gcc 4.9.1 (snapshot
4.9-20140903), binutils 2.24 [1], clang 3.5.0).

[1] The binutils package has a patch which suspiciously looks like it should 
handle the issue

It may be that llvm 3.5 + mesa is "using" gcc/binutils in a slightly different 
way.
Can you try using the same versions as the one I've listed ? This way if it 
works one can start looking for the combination that exhibits the problem.

If the function prototype has changed then a compiler warning is due. Afaict 
your issue is at a later stage - link time.

I would recommend disabling LTO until one is able to clearly establish the root 
cause. After it's sorted you can get it back on for llvm.

I would recommend that you try the patch, before doing anything.

There is not much of a benefit in (re-)posting "power management does not 
work", most people are aware about this and working on it one way or the other. 
If you really want to help, be more understanding and work with the nouveau 
team rather than posting annoying replies.

Btw have you realised the _massive_ amount of work that PM is ? The
AMD/ATI DPM code that landed in linux 3.11 is over 50kloc and all of it
was done by the vendor.

Thanks

It appears that even the blob was experiencing the same issue [1]

Affected blob 180.44, fixed in 180.60. I would expect that a specific
quirk was added to handle the issue

Did you have the chance to test a kernel that includes the following
commit

"drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of
issues"


It does rework the gpio handling and initialization (among other things), that 
should have positive effect on your issue 

It is part of linux 3.3rc1 [1] as well as nouveau linux tree [2]


Cheers

[Bug 925048]

2012-02-08 Thread Emil-l-velikov
Hello Bryce

Here are some tips that will help triage the issue

* Is the person using "3d" - try reproducing the issue without it
Disable AIGLX in the X server
(Re)move the file (or package providing it) 
"/usr/lib/x86_64-linux-gnu/dri/nouveau_dri.so"

* Try booting with "nouveau.nofbaccel=0"

* Amend the previous option to read "nouveau.noaccel=0"


Although before attempting any of the above I would recommend trying the git 
master branch (or as close as) of the following

* [1] xf86-video-nouveau
* [2] kernel
* [3] mesa

Note that those tips can be used for any case/issue

Cheers
Emil

According to the latest dmesg (in comment #47)

Nouveau fails to "Suspend the GPU objects" due to NOMEM (-12 reported in
the log),

I.e. nouveau fails to vmalloc(gpuobj->size), that is needed to store
current gpu objects (so that they can be restored after resume)

For anyone still experiencing this bug, here is a possible workaround
(thanks to ColdFeetBob for pointing it out)

Modify* /xserver/mi/mieq.c and rebuild xserver
* Increase the "#define QUEUE_SIZE 512" to 1024, 2048 or 4096 [1]

Note that this is *not* a proper fix as you can see in the discussion
