[igt-dev] [PATCH i-g-t v3 1/3] lib/rendercopy: Add gen4/5 rendercopy
Lukasz Kalamarz
lukasz.kalamarz at intel.com
Thu Jul 12 14:15:22 UTC 2018
Add rendercopy implementation for gen4/5. Basic structure
copied from the gen6 implementation, and the gen4/5 specific
bits were mostly lifted from sna.
v2: Renamed registers definitions, which are GEN4 specific
to include that prefix (Lukasz)
v3: Rebase and checkpatch
