[igt-dev] [PATCH i-g-t v6 10/10] i915_pm_rpm: Extend gem-mmap-type test with D3Cold

Mon May 16 15:12:55 UTC 2022
Added d3cold dynamic subtest to gem-mmap-type with device class
memory region. It test both D3Cold-{VRAM_SR, Off} by using
d3cold_sr_lmem_threshold i915_params debugfs.
v2:
- Two different subtest d3cold-off and d3cold-vrsr. [Rodrigo]
v3:
- Skip the d3cold-vram-sr test when lmem_threshold is not available.
