Description Shuang He 2007-09-25 23:21:20 UTC

System Environment:
--------------------------
latest Mesa, Drm, Xserver, Xf86_video_intel


Bug detailed description:
--------------------------
During running glean test case depthStencil, one assertion is failed:
i915_vtbl.c:427: i915_emit_state: Assertion `(state->Program[0] & 0x1ff) + 2 == state->ProgramSize' failed.

And the test case aborted.

Reproduce steps:
----------------
you can run it by:
glean -r resultdir -t depthStencil


Current result:
----------------
----------------------------------------------------------------------
Test the GL_EXT_packed_depth_stencil extension.

depthStencil:  PASS rgba8, db, win+pmap, id 35
        glReadPixels GL_DEPTH_STENCIL rate: 0.00 MBytes per second.
        glReadPixels GL_DEPTH/GLuint rate: 0.00 MBytes per second.
        glReadPixels GL_DEPTH/GLushort rate: 0.00 MBytes per second.
depthStencil:  PASS rgba8, win+pmap, id 36
        glReadPixels GL_DEPTH_STENCIL rate: 0.00 MBytes per second.
        glReadPixels GL_DEPTH/GLuint rate: 0.00 MBytes per second.
        glReadPixels GL_DEPTH/GLushort rate: 0.00 MBytes per second.
glean: i915_vtbl.c:427: i915_emit_state: Assertion `(state->Program[0] & 0x1ff) + 2 == state->ProgramSize' failed.
Aborted



Expected result:
----------------
this glean case should pass without any error

Comment 1 Shuang He 2007-09-27 00:00:17 UTC

seems i915-unification merge brings this issue in
we are using mesa commit(f388d62b39e9273dd8aac425da54015af91192d8)

Comment 2 Shuang He 2007-09-27 23:05:07 UTC

Created attachment 11795 [details]
test case

This issue can be reproduce by running this simple test case (it's actually for bug #12095)

Comment 3 Pi, Fengming 2007-11-30 01:05:04 UTC

Using the git code,this bug still exists.

Mass version move, cvs -> git
