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=c2c55547dc36f404e29dbc9253166f90df6783af
The corresponding debug option here:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=6baad55f157387d0bb44144680a96bc32280109f
I dunno how this should have ever worked, when the kernel immediately rejects
these formats?
