Priority: medium
Bug ID: 75212
CC: e...@anholt.net, lem...@gmail.com
Assignee: mesa-dev@lists.freedesktop.org
Summary: Mesa selects wrong DRI driver
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: eero.t.tammi...@intel.com
Hardware: x86 (IA32)
Status: NEW
Version: git
Component: GLX
Product: Mesa
Test environment:
- HSW GT3e
- Up to date Ubuntu 13.10
- Latest versions of libdrm and mesa built (from today's git master),
with only i965 driver enabled
Steps to reproduce:
1. Run glxgears with latest mesa
Expected output:
- i965 driver loaded & HW acceleration used
Actual output:
- Mesa complains that it doesn't find i915 nor swrast
- glxgears runs really slowly
Bisecting Mesa identified this commit as culprit:
----------------------------------
commit 7bd95ec437a5b1052fa17780a9d66677ec1fdc35

dri2: Trust our own driver name lookup over the server's.
This allows Mesa to choose to rename driver .sos (or split drivers),
without needing a flag day with the corresponding 2D driver.
v2: Undo the loader-only-for-dri3 change.
----------------------------------
If Mesa needs some new dependency or specific version of that to identify on
which HW it's running, it should check for that in configure.
