[igt-dev] [PATCH i-g-t 0/2] Support custom contexts in exec_blit()

[Karolina Stolarek]

The series changes how exec_blit() sets blitter engine id in
execbuf used by igt_blitter_src_copy() and
igt_blitter_fast_copy__raw(). Currently, the function assumes
a legacy engine identifier, which won't work for contexts that
have non-standard engine layout.

With this patch series, it will be possible to find a copy
engine based on intel_ctx_cfg_t passed in by the blitter
copy functions. To make it possible, find_engine() had to be
slightly modified. Here, instead of using intel_bb (which
limits the function usage to this structure only), we use
context config extracted from intel_bb, making find_engine()
more flexible.

  lib/intel_batchbuffer: Make find_engine() more flexible
  lib/intel_batchbuffer: Use correct engine id in exec_blit()
