[PATCH i-g-t 0/2] check modparam before enabling psr mode

[Kunal Joshi]

with i915.enable_psr modparam, one can enable required psr version

i915.enable_psr = 0 PSR_1 and PSR_2 tests should skip
i915.enable_psr = 1 PSR_1 tests should run but PSR_2 tests should skip
i915.enable_psr = 2 PSR_1 and PSR_2 tests should run

fix test to check modparam before enabling through psr_debug debugfs

Kunal Joshi (2):
  lib/igt_psr: add helper to check of given psr mode can be enabled
  tests/intel/kms_psr: enable given psr mode only after checking
    enable_psr modparam
