[PATCH i-g-t, v8 3/4] tests/kms_sharpness_filter: Add adaptive sharpness filter test

Fri Nov 22 18:57:07 UTC 2024


New test is added to validate adaptive sharpness filter on
LNL platform. Various testcases are added to validate this
feature. These are non CRC based tests and manual verification
is required.

Pipe scaler is repurposed to perform a portion of this work.
This means pipe scaling will be unavailable while the sharpening
function is being used. The other scaler can be used for plane
scaler.

15 subtests are added:
	-basic: verify basic functionality
	-toggle: switch between enable and disable
	-tap: verify different taps selected based on resolution
	-modifiers: verify casf with different modifiers
	-rotation: verify casf with different rotation
	-formats: verify casf with different formats
	-dpms: verify casf with dpms
	-suspend: verify casf with suspend
	-upscale: apply plane scaler and casf together
	-downscale: apply plane scaler and casf together
	-strength: vary strength and check difference in sharpness
	-invalid filter with scaler: enable scaler on 2 planes and attempt
				     is made to enable casf
	-invalid filter with plane: enable 2 NV12 planes and attempt
				    is made to enable casf
	-invalid plane with filter: enable 1 NV12 plane and casf and attempt
				    is made to enable 2nd NV12 plane
	-invalid filter with scaling mode: enable scaling_mode property and attempt
					   is made to enable casf

TODO: -Enable casf with varying output formats (YCBCR/RGB)

v2: -Updated modifier type to uint64_t.
    -Replaced IGT_CRTC_SHARPENESS_STRENGTH with IGT_CRTC_SHARPNESS_STRENGTH.
v3: -Updated setup_fb with height and width.
v4: -Renamed tests/intel/kms_sharpness_filter.c -> tests/kms_sharpness_filter.c (Ankit)
    -Added subtest invalid filter with connector. (Ankit)
    -Updated documentation. (Bhanu)
    -Used driver_close_driver instead close. (Bhanu)
    -Added check to avoid debug print for invalid tests and filter strength = 0. (Ankit)
v5: -Instead of using default strength as MAX, use MID value strength.
    -Add relevant debug print for test skip.
    -Fix indentation.
    -Renamed invalid-filter-with-connector -> invalid-filter-with-scaling-mode
    -Reworked on invalid-filter-with-scaling-mode(), added provision to
     validate other scaling modes.
v6: -Skip test if ret=-EINVAL for downscaling test.
    -Change if() for tap subtest.
v8: -Optimize tap-filter subtest (Ankit)
