Priority: medium Bug ID: 60969 Assignee: dri-devel@lists.freedesktop.org Summary: [r600g] Lockup while playing OpenGL games with HD6450 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: rankincj@googlemail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
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.
