--- Comment #2 from Tobias Jakobi liquid.acid@gmx.net 2011-02-06 07:50:48 PST --- I just noticed that there is the R600_ENABLE_S3TC option and tried to enable it.
However this triggers the CS checker in the kernel and reject most of the commands. Tried with Max Payne 2 and FEAR, since I know that these two use texture compression when available (MP2 even in the menu): 1) MP2 just displays a black screen 2) FEAR works in the menu, but crashes when going ingame
In both cases I get an error from r600_check_texture_resource (r600_cs.c), which comes from r600_bpe_from_format not knowing the FMT_BCx formas.
The format code was introduced in this commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=c2c55547dc36f404e29dbc92531...
The corresponding debug option here: http://cgit.freedesktop.org/mesa/mesa/commit/?id=6baad55f157387d0bb44144680a...
I dunno how this should have ever worked, when the kernel immediately rejects these formats?
