[igt-dev] [PATCH i-g-t v34 05/40] lib/intel_batchbuffer: add new functions to support rendercopy
Zbigniew Kempczyński
zbigniew.kempczynski at intel.com
Fri Sep 11 08:07:22 UTC 2020
To cover rendercopy in dependent tests we need to add the following:
1. relocation in any handle
Previously batchbuffer was the main target of relocations. As AUX
table require relocations too add support for that in intel_bb
2. set/get default alignment
Add default alignment for objects added to intel_bb (AUX tables use
different alignment for different objects)
3. add intel_buf to intel_bb
Save proposed address to intel_buf, clear flags on reset
4. add set/clear flag functions
5. unification of intel_bb_flush.*() functions
6. fixing indentation
7. change alignment constraints on gen3
