[PATCH] radeon: Fix KMS CP writeback on big endian machines.

2011-04-07 Thread Michel Dänzer
From: Michel D?nzer 

This is necessary even with PCI(e) GART, and it makes writeback work even with
AGP on my PowerBook. Might still be unreliable with older revisions of UniNorth
and other AGP bridges though.

[Bug 36065] New: r600g regression : vertex buffer alignement

2011-04-07 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=36065

   Summary: r600g regression : vertex buffer alignement
   Product: DRI
   Version: XOrg CVS
  Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: pell...@gmail.com


I have a simple app using vbo to render models.
The VBO layout is : position (3 float), normal (3 float), color (3 char)

This app was running perfectly until I updated libdrm/mesa to git version.
Now the app still does not have any GL error set (checked with glGetError()),
but its rendering is completely wrong.

git-bisect pointed me to this commit :
  0ed5bf668db24fb56b5b359399099c89531e2a0a

Does S3TC work in other games? If not, it's a more general problem. (I'm not
sure if S3TC works equally well for all r600g hardware, or only on Evergreen?)

Float textures only exist in marek's branch, and only for r300g, so it's
probably a bit premature to file bugs about this. Amensia works without it,
you're just missing out on a couple of effects.

Right now, the RendererFeatTest doesn't work properly at all if I enable the
S3TC extension with mesa git version, libdrm git version and libtxc_dxtn git
version.

Not forcing the S3TC extension, the first test shows corruption on text
(written on top left corner) while the i915 doesn't. All the test fails to show
the background which is probably related to a texture not loaded because of
missing S3TC extension or because of float textures not supported. SSAO (used
in test 10) and Edge smooth (used in test 14) are disabled because of float
textures not supported.

Should we report problem with RendererTestFeat in different bugs (listing each
problem as a different bug, i.e. S3TC and Float Textures)?

 Review: https://bugs.freedesktop.org/review?bug=36037&attachment=45386

Debugging patch

This patch (only compile tested) should print the pointer values before
referencing them, and bail if one of them is NULL. This should also avoid the
immediate crash, but it might still crash elsewhere later on.

Thanks, but I mean modifying radeon_legacy_backlight_get_brightness() to print
the value of each pointer before dereferencing it. If you don't know how to do
that, I can try whipping up a test patch.

This is necessary even with PCI(e) GART, and it makes writeback work even with
AGP on my PowerBook. Might still be unreliable with older revisions of UniNorth

Looks like one of the pointers in radeon_legacy_backlight_get_brightness() is
NULL, but I'm not sure which one that could be. Johannes, can you add some
debugging output to see which one it is?

[Bug 35425] Instanced drawing: not implemented

2011-04-07 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=35425

--- Comment #1 from s3734...@mail.zih.tu-dresden.de 2011-04-07 01:12:01 PDT ---
The PipeCap for instanced drawing is available, the drivers implement them,
TGSI has the construct TGSI_SEMANTIC_INSTANCEID.

The only component that does not support instanced drawing is the GLSL
compiler.

So can please any of the GLSL guys implement the gl_InstanceID uniform?
