[PATCH v9 0/8] Add DSC PPS readout

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Up until now we only verified one or two of the dsc pps
params like bits_per_component and bits_per_pixel this
patch series aim to readout almost all PPS param and get
them compared.
Along with that some work on making a common function to
read and write PPS param regiters is also done.

--v2
-Remove duplicated code and create function that fetches register
and reuse that. [Jani]
-move WARN_ON one abstraction layer up. [Jani]
-Split patch so that refactor and a new functionality is not added
in the same patch. [Jani]
-Add a new refactor patch so that bit shifting can be done in a
clean way. [Jani]

--v3
-Fix the typo in patch 2 [Jani]
-Get both dsc_reg regardless of dsc_eng_no. [Jani]
-Remove usage of num_vdsc_instances. [Ankit]
-Add macro to further optimize intel_dsc_get_pps_reg

--v4
-Manipulate register addresses rather than creating a macro to
manipulate variable name based on pps [Ankit]

--v5
-Use an array to fill the dsc registers instead of individual register
[Ankit]
-Get only dsc register that are required.

--v6
-make intel_get_no_vdsc_inst_per_pipe func static

--v7
-shorten func name for getting vdsc instances per pipe [Ankit]
-send no vdsc instances to dsc read and write reg funcs [Ankit]

--v8
-remove array dynamic allocation for dsc_reg [Jani]
-no need for an array to just verify dsc engine values [Jani]
-remove no_ from no_vdsc_per_pipe and wherever else it is
applicable [Ankit]

--v9
-change variable name to dsc_reg_size in intel_get_pps_reg [Ankit]
-send ARRAY_SIZE(dsc_reg) in intel_dsc_write_pps_reg [Ankit]
