Test environment: Pineview Kernel_version: 2.6.36-rc2_unstable_20100907+ Libdrm: (master)2.4.21-18-g23287f05cf2443ddf9e028e29beb5bd30979c6cf Mesa: (master)4a730b773f0cae9ff5defb407bb2b7ca43234c35 Problem: piglit nodepth-test has failed on Pineview(i915) since we started to test it on Pineview on 2010-05-19. While it passes on Piketon(i965). Output: Probe at (0,0) Expected: 0.000000 1.000000 0.000000 Observed: 1.000000 0.000000 0.000000 PIGLIT: {'result': 'fail' }

commit fc4fba52cf7e9616c70dd76b4d6bdba6582e157b Author: Eric Anholt <eric@anholt.net> Date: Tue Jul 12 10:48:40 2011 -0700 i915: Disable the depth test whenever we don't have a depth buffer. We were disabling it once at the moment we changed draw buffers, but later enabling of depth test could turn it back on. Fixes fbo-nodepth-test. Note that ctx->DrawBuffer has to be checked because during context create we get called while it's still unset. However, we know we'll get an intel_draw_buffer() after that, so it's safe to make a silly choice at this point. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30080
