HD6450 (CAICOS), kernel 3.7.7-201.fc18.x86_64 The PC quickly locks up while playing either WoW or Minecraft 1.4.7 with Mesa from git. However, I have an earlier version of Mesa-git that plays both games correctly. The mouse cursor continues to move after the freeze, but the keyboard no longer responds. The HEAD for my working Mesa is: commit 0e2f26d5ea26febd16173aa8bbf7427b090e320f Author: Ian Romanick <ian.d.romanick@intel.com> Date: Fri Feb 8 18:03:33 2013 -0800 intel: Do not expose OES_compressed_ETC1_RGB8_texture or ARB_texture_rgb10_a Older hardware cannot do ARB_texture_rgb10_a2ui, and the translation code for OES_compressed_ETC1_RGB8_texture was never implemented in the i915 driver. I will try and bisect this issue when I have more time with the affected PC. Note that this issue does not happen with either my HD4670 or HD4890.
According to git bisect: 974b482acaf62ced1e8981761a8bda252bd51fe1 is the first bad commit commit 974b482acaf62ced1e8981761a8bda252bd51fe1 Author: Jerome Glisse <jglisse@redhat.com> Date: Fri Feb 8 16:02:32 2013 -0500 r600g: fix lockup when hyperz & alpha test are enabled together. v3 Seems that alpha test being enabled confuse the GPU on the order in which it should perform the Z testing. So force the order programmed throught db shader control. v2: Only force z order when alpha test is enabled v3: Update db shader when binding new dsa + spelling fix Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Marek Olšák <maraeo@gmail.com> This results in GPU stalls, which can be reset succesfully.
Created attachment 74995 [details] dmesg output frpm GPU lockup/reset This dmesg log shows the GPU lockups and soft resets that occurred during my git bisect.
