[Mesa-dev] [PATCH 1/3] gm107/ir: Emit SV_CLOCK system value

[Ilia Mirkin]

Did you check what the blob does? There's clocklo/hi and
globaltimerlo/hi. Without additional documentation, it's a bit hard to
tell the difference... Note that envydis's gf100.c/gk110.c disagree on
which is which. Probably not due to any architectural reasons, but due
to RE methodology. (From before nvdisasm was
available/trusted/used/whatever.)
