[Bug 60879] [radeonsi] X11 can't start with acceleration enabled

https://bugs.freedesktop.org/show_bug.cgi?id=60879

--- Comment #78 from Michel Dänzer michel@daenzer.net --- (In reply to comment #76)

this should be:

•    for (i = 0; i < rdev->config.cik.max_texture_channel_caches; i++)
  

•            cgts_tcc_disable &= ~(1 << (16 + i));
  

Why? This is si_gpu_init().

[...]

•    WREG32(CGTS_TCC_DISABLE, cgts_tcc_disable);
  

My understanding is that this register indicates which TCCs are not functional. So this line should be replaced by

cgts_tcc_disable |= RREG32(CGTS_TCC_DISABLE);
