Bug ID: 94025 Summary: [bisected] r600_texture.c:562: r600_texture_get_htile_size: Assertion `0' failed Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: alexandre.f.demers@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Created attachment 121557 --> https://bugs.freedesktop.org/attachment.cgi?id=121557&action=edit backtrace
Since yesterday night, I've been unable to get a window manage running (see attached backtrace). After bisecting Mesa (was the only thing recompiled), I found out that the following commit was the culprit. Any application being launched while bisecting from and after that commit ends up with a "r600_texture.c:562: r600_texture_get_htile_size: Assertion `0' failed" error.
294ec530c9829aead97487b1feb06361ef97cc2d is the first bad commit commit 294ec530c9829aead97487b1feb06361ef97cc2d Author: Marek Olšák marek.olsak@amd.com Date: Sat Jan 30 01:52:58 2016 +0100

--- Comment #1 from Alexandre Demers alexandre.f.demers@gmail.com --- I added a line to output the value of "num_pipes" when it can't be matched to the defined values in the switch: fprintf(stderr, "Driver was unable to determine num_pipes (value = %i)\n", num_pipes);
I ended up outputting "Driver was unable to determine num_pipes (value = 12)", which is not coverded in the switch... Expected?
In commit 294ec530, r600_get_gb_tiling_config() was removed. num_pipes was defined there and a comment was telling: "/* Convert Sea Islands register values GB_ADDR_CFG and MC_ADDR_CFG * into GB_TILING_CONFIG register which is only present on R600-R700. */"
I'm using and R9 290X, which is a Sea Islands, covered by this comment.

--- Comment #2 from Alexandre Demers alexandre.f.demers@gmail.com --- (In reply to Alexandre Demers from comment #1)
I'm using and R9 290X, which is a Sea Islands, covered by this comment.
I meant R9 280X (Tahiti family, thus Southern Islands). So, was it included in the removed r600_get_gb_tiling_config()? It seems so, but then the comment would have been slightly wrong.

--- Comment #3 from Alexandre Demers alexandre.f.demers@gmail.com --- With the code prior to the bad commit, num_pipes was defined as 8 (while now it is 12, thus hitting default and asserting)...
