Summary: [bisected, r300g] Unigine Sanctuary: r300_emit.c:902:r300_emit_vertex_arrays: Assertion `&buf->b.b' failed with RADEON_HYPERZ=1 Product: Mesa Version: git Platform: Other URL: http://unigine.com/download/#sanctuary OS/Version: All Status: NEW Keywords: have-backtrace, regression Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: drakkk@centrum.cz

Created an attachment (id=41767) --> (https://bugs.freedesktop.org/attachment.cgi?id=41767) terminal output with backtrace

When Unigine Sanctuary is started with RADEON_HYPERZ=1 it asserts almost immediately. This is with all graphic settings set to lowest possible.

First bad commit: be1af4394e060677b7db6bbb8e3301e38a3363da Author: Marek Olšák maraeo@gmail.com Date: Sun Dec 26 04:29:44 2010 +0100

r300g: derive user buffer sizes at draw time

This only uploads the [min_index, max_index] range instead of [0, userbuf si which greatly speeds up user buffer uploads.

This is also a prerequisite for atomizing vertex arrays in st/mesa.

BTW I had to also manually apply 96d8a54716d96bd28f0c54a25ca6904fb4321a55, I suppose it doesn't change anything
