Bug ID: 88619
Summary: [r300g] multiple tex-miplevel-selection tests crash
with "u_blitter:494: Caught recursion. This is a
driver bug."
Product: Mesa
Version: git
Hardware: x86 (IA32)
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r300
Assignee: dri-devel at lists.freedesktop.org

Recently around 20 tex-miplevel-selection test regressed on my RV530.
Specifically this concerns the tex-miplevel-selection {1D,2D,2DRect}Shadow
tests eg.
tex-miplevel-selection *GradARB 1DShadow -auto -fbo
tex-miplevel-selection *GradARB 2DRectShadow -auto -fbo
tex-miplevel-selection GL2:texture() 2DRectShadow -auto -fbo
and others.
It used to work approximately one month ago and I tried to bisect mesa, however
I was unable to find a good commit, so the regression must have happened in
some other component. My best guess at this moment is some piglit change. Those
tests are the only crashing piglits on my RV530 at the moment.
Backtrace from one selected test:
