[igt-dev] [v3 01/10] tests/i915/kms_dsc: add new test flag

[Swati Sharma]

Add new test flag TEST_DSC_FORMAT. This flag is added to
differentiate the basic dsc test and the tests where we want to
change different plane pixel formats.

Instead of using enum, use uinit32_t test flag. It is helpful,
if we need to implement feature combination tests.

[Swati Sharma]

For default bpc, use #define. By setting bpc as 0, means driver
will set its own value and we are not enforcing input bpc.

[igt-dev] [v3 07/10] tests/i915/kms_dsc: enable validation for vdsc fractional bpp

[Swati Sharma]

Intel hardware supports fractional bpp from display_ver >= 14.
To test fractional bpp, debugfs entry (force_dsc_fractional_bpp)
is introduced. From the IGT; we are setting this debugfs entry.
However, before setting this debugfs entry, we are checking
capability i.e. fractional bpp is supported by platform and sink
both. In driver, if force_dsc_fractional_bpp is set then while
iterating over output bpp with fractional step size we will
continue if output_bpp is computed as integer and allow DSC iff
compressed bpp is fractional.

v2: -change in igt_describe (Ankit)
v3: -rebase
v4: -add wrapper for source support of fractional bpp (Ankit)

+ * (iv) output formats (v) fractional bpp

+ * subtest, we verify output formats (RGB/YCBCR444/YCBCR420).
+ * Fractional bpp is tested with default parameter. In this,
