Workarounds for bdw are currently applied in init_clock_gating() but they
are lost following a gpu reset. Some of the registers are part of register
state context and they are restored with every context switch so initializing
WAs in golden render state ensures that they are applied even when we start
with an uninitialized context or during hw initialization followed by a reset.
Interesting, but let's try to keep the opaque blobs minimal. The
comments for w/a are even more valuable than the code.
I agree, I will add comments to each workaround.
We are looking at augmenting workarounds to the null batch in render
state setup function itself. Do you have any comments with that approach?

Arun
