depend on whether tessellation is enabled or disabled.

This affect me too, in a R9 290, radeonsi driver, using padoka PPA with Kubuntu
16.04.

When you disable tesselation in those games the problem goes away.

ci-64-tess-blocks.patch

Does the attached patch help? If not I would appreciate it if someone could
find the first commit that fails (using e.g. bisect).

Also, I noticed all reporters use hawaii/grenada pro chips. If anyone with a
different chip also has this issue, please let me know.

Unfortunately, ci-64-tess-blocks.patch is making the issue more severe. The
frequency of "black triangles on screen" in Tomb Raider is higher.

Checking out for example f91c85b29b8261ab3f44d292ed2130d4f577d976 and starting
Tomb Raider restarts the X server on my machine.

S_03093C_OFFCHIP_BUFFERING(offchip_blocks) if >= CIK

This patch fixes the issue on my R9 390.

The code is just a guesswork. Maybe it should be (2*offchip_blocks-1) instead?

Passing +1 to S_03093C_OFFCHIP_BUFFERING() explains why changing offchip_blocks
from 256 to 64 increases the severity of the issue.

Thanks a lot for finding the cause of the issue.

I pushed e9d3246a7a74282fbbf95ed077e3c3b7750c8ddd to git, that patch should fix
the issue.
