Results for glean/readPixSanity

readPixSanity fails with both Mesa 7.11 and current git (2154c672b3f2a0f3de7aaacd9260954b9310262a) on ATI Technologies Inc RS880 [Radeon HD 4250] using the Gallium R600 driver.

Test failure is:

With http://lists.freedesktop.org/archives/mesa-dev/2011-September/011977.html applied, the DRI2SwapBuffers error goes away and there's opportunity to fail even more tests.
Comment 3 Jure Repinc 2011-09-24 04:41:48 UTC
Same here, it's fixed in latest mesa from git. So I guess this bug can be closed.
Comment 4 Nicholas Miell 2011-09-24 10:23:26 UTC
Mesa d7cdbc3c5415d2dd5eee58834b13714a89eacf2b and Piglit bda09aeb20f183407038672318c8f657feb9fe54 still fail.

Please do not unilaterally close random bugs that you didn't originally file.
Comment 5 Marek Olšák 2011-09-24 10:26:12 UTC
Does it pass after a clean boot?
Comment 6 Nicholas Miell 2011-09-24 13:09:11 UTC
When booting to runlevel 3 and using startx with an .xinitrc that starts only an xterm, both the basic and readPixSanity tests fail.

basic:
Returncode: 1

Errors:
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  72 (X_PutImage)
  Resource id in failed request:  0x600011
  Serial number of failed request:  91
  Current serial number in output stream:  95


Output:
----------------------------------------------------------------------
This trivial test simply verifies the internal support for basic
tests.  It is run on every OpenGL-capable drawing surface
configuration that supports creation of a window.

basic:  PASS rgba8, db, z24, s8, win+pmap, id 33
basic:  PASS rgba8, db, z24, s8, win+pmap, id 34
basic:  PASS rgba8, db, z24, s8, win+pmap, id 109
basic:  PASS rgba8, win+pmap, id 254


readPixSanity:
Returncode: 1

Errors:
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  72 (X_PutImage)
  Resource id in failed request:  0x600011
  Serial number of failed request:  2090
  Current serial number in output stream:  2094


Output:
----------------------------------------------------------------------
This test performs a sanity check of glReadPixels, using as
few other portions of the GL as possible.  If this test fails,
it may be pointless to run other tests, since so many of them
depend on reading the contents of the framebuffer to determine
if they pass.

The test works by using glClear to fill the framebuffer with a
randomly-chosen value, reading the contents of the
framebuffer, and comparing the actual contents with the
expected contents.  RGB, RGBA, color index, stencil, and depth
buffers (whichever are applicable to the current rendering
context) are checked.  The test passes if the actual contents
are within 1 LSB of the expected contents.

readPixSanity:  PASS rgba8, db, z24, s8, win+pmap, id 33
	RGBA largest readback error was 0 bits
	Depth largest readback error was 0 bits
readPixSanity:  PASS rgba8, db, z24, s8, win+pmap, id 34
	RGBA largest readback error was 0 bits
	Depth largest readback error was 0 bits
readPixSanity:  PASS rgba8, db, z24, s8, win+pmap, id 109
	RGBA largest readback error was 0 bits
	Depth largest readback error was 0 bits
readPixSanity:  PASS rgba8, win+pmap, id 254
	RGBA largest readback error was 0 bits

I see just PASS.

Not all of the tests run due to the X error, and the test harness reports failure for both of them.
Comment 9 Nicholas Miell 2011-09-24 23:17:00 UTC
OK, startx + .xinitrc wasn't initializing a ConsoleKit session, so my account wasn't getting added to the ACL on /dev/dri/card0 and piglit was running on indirect GLX.

Having sorted that out, the BadDrawable errors are gone, the basic test is passing, and the readPixSanity test is failing in the same way as the "updated results" attachment.
Comment 10 ojab 2012-06-26 02:20:10 UTC
I have the same issue on
01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780D [Radeon HD 3300]
OpenGL renderer string: Gallium 0.4 on AMD RS780
OpenGL version string: 2.1 Mesa 8.1-devel (git-cc2cd8b)
OpenGL shading language version string: 1.30

using piglit from git (5c51c7b msaa/formats: Add EXT_texture_sRGB tests)

X.Org X Server 1.12.0
libdrm-git (ae137f4 intel: Add IVB PUSH_CONSTANT decodes)
xf86-video-ati-git ( 5dc5012 radeon: dixPrivateKeyRegistered is only in server 1.9)
kernel-3.4.2

Please tell me if any additional info is needed for investigation.

Still the same with mesa git-11ff18f

And update to the kernel-3.5 doesn't change anything.
llvmpipe works without such issues.

Please stop spamming this report with 'still happens' comments. It's safe to assume that the problem is still there while there are no updates. Thanks.
