--- Comment #1 from Ilia Mirkin ---
Wow, very uncommon configuration... nouveau as main and intel as "GPU". Are you
doing any actual offloading (of either outputs or rendering)?
exa/exa_migration_mixed.c:FatalError("EXA: malloc failed for
size %d bytes\n",
pExaPixmap->sys_pitch * pPixmap->drawable.height
exa/exa_priv.h:int sys_pitch; /**< pitch of pixmap in system
memory */
include/pixmapstr.h:unsigned short height;
I guess sys_pitch is somehow negative then.
Can you "bisect" the test, i.e. figure out which bit of it triggers the issue?
And perhaps modify that print to show what the individual values in that
multiplication are?

Running wine's dlls/user32/tests/win.c tests under valgrind causes the X client to fail, killing the user session.

[Nouveau] [Bug 91551] DXTn compressed normal maps produce severe artifacts on all NV5x and NVDx chipsets
https://bugs.freedesktop.org/show_bug.cgi?id=91551 --- Comment #10 from Ilia Mirkin --- Ah, I suspect the remaining issues are due to the fact that we're encoding things like 119: mad f32 $r75 $r4 2.00 $r75 (8) as e92d 0403 add sat f32 $r11 (mul $r4 0x4000) $r11 Which... might not be *exactly* the same thing. Unfortunately there *is* no encoding for that instruction, the nv50 emitter isn't smart enough not to emit it. Shaders with > 64 regs are sufficiently rare :( I guess we need to add a post-RA fixup to load these immediates for non-encodable instructions. Of course the question is *where* to load it... ugh. Could try to reserve a special register at RA time for it... -- You are receiving this mail because: You are the QA Contact for the bug.

[Nouveau] [Bug 91551] DXTn compressed normal maps produce severe artifacts on all NV5x and NVDx chipsets
https://bugs.freedesktop.org/show_bug.cgi?id=91551 --- Comment #9 from Ilia Mirkin --- As I suspected, nothing to do with compressed textures. Should be at least partially fixed by commit ce28ca713364dbe83cb3c371ca034bc2c2947616 Author: Ilia Mirkin Date: Thu Sep 10 03:55:06 2015 -0400 nv50/ir: fix emission of 8-byte wide interp instruction This can come up if the target register number is > 63, which is fairly rare. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91551 Signed-off-by: Ilia Mirkin Cc: "11.0" It still doesn't seem to render quite the same as nvc0 and llvmpipe. The lighting on the back of the spinning models is much brighter. Not sure why... those shaders are ENORMOUS by the way. I thought it might be due to glShadeModel(GL_FLAT) at first, which isn't properly handled, but that's not it -- it only ever calls glShadeModel(GL_SMOOTH) in the trace. -- You are receiving this mail because: You are the QA Contact for the bug.

[Nouveau] [Bug 90887] PhiMovesPass in register allocator broken
https://bugs.freedesktop.org/show_bug.cgi?id=90887 --- Comment #39 from Ilia Mirkin --- I pushed the following after some light testing: commit a072ef8748a65d286e9b542bb9ea6e020fdcc7f8 Author: Ilia Mirkin Date: Thu Sep 10 01:54:30 2015 -0400 nv50/ir: make edge splitting fix up phi node sources But it's not the final word on this stuff... as Béla mentioned in comment 13, some games aren't completely fixed by this. I have some Hearthstone traces (from bug #75776) which still have minor visual artifacts. Further, they are fixed by splitting more edges. [I made the condition only look at p->cfg.outgoingCount() > 1, which includes a whole lot more than critical edges. This is clearly wrong, but... gives some ideas.] -- You are receiving this mail because: You are the QA Contact for the bug.
