Summary: RV670 AGP lodbias regression since st/mesa: remove unnecessary flushes Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: lists@andyfurniss.entadsl.com
rv670 AGP but running agpmode=-1 as agpgart + gallium locks on this box. kernel d-r-t, git ddx with tiling enabled in xorg.conf. Does not affect my PCIE RV790 box.
Mesa demo lodbias does not work normally since
commit bdf103894026238c7e896eccb995b141161bfb70 Author: Marek Olšák maraeo@gmail.com Date: Tue Mar 8 00:28:33 2011 +0100
st/mesa: remove unnecessary flushes
The framebuffer cache flush should be implicit when calling set_framebuffer_state.
There is no need to flush the command stream either.
It disappears to black too quickly between 1.5 and 2.5 and the image is corrupt rather than blurring gradually during this time.

This is a driver-specific bug and the patch in bug 35312 is not a fix, it's a bloody hack.
