drm/amd/display: Use kfree() to free rgb_user in calculate_user_regamma_ramp()

2020-06-10T22:00:24Z

Use kfree() instead of kvfree() to free rgb_user in calculate_user_regamma_ramp() because the memory is allocated with kcalloc(). Signed-off-by: Denis Efremov Signed-off-by: Alex Deucher

drm/amd/display: Use kvfree() to free coeff in build_regamma()

2020-06-10T22:00:24Z

Use kvfree() instead of kfree() to free coeff in build_regamma() because the memory is allocated with kvzalloc(). Fixes: e752058b8671 ("drm/amd/display: Optimize gamma calculations") Cc: stable@vger.kernel.org Signed-off-by: Denis Efremov Signed-off-by: Alex Deucher

drm/amd/display: move location of dmub_srv.h file

2020-05-05T17:12:33Z

[Why] Make a separation of what belongs in the differen dmub headers dmub_srv.h is for exposing dmub srv interface to rest of driver. other headers inside dmub/inc exposes cmds and definitions that are owned by the firmware [How] keep firmware owned definitions in dmub/inc move stuff that is purely driver interface headers to dmub/ since those are interface calls that are defined for rest of driver to use Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Harry Wentland Acked-by: Aurabindo Pillai Signed-off-by: Alex Deucher

drm/amd/display: add addition dc type to translate to dmub fw type

2020-05-05T17:11:49Z

[Why] For a type like PSR version, it makes sense for most of the code to include a dc type, instead of having this a fw type define since this is a capability and type exposed by dc. Especially if it doesn't even need to communicate with the fw. The code that is packing the firmware command message should be the one who needs to translate the psr version into a command that the firmware understands. [How] Add a dc_psr_version enum.

drm/amd/display: Internal refactoring to abstract color caps

2020-04-28T20:19:48Z

[Why&How] modules/color calculates various colour operations which are translated to abstracted HW. DCE 5-12 had almost no important changes, but starting with DCN1, every new generation comes with fairly major differences in color pipeline. We would hack it with some DCN checks, but a better approach is to abstract color pipe capabilities so modules/DM can decide mapping to HW block based on logical capabilities, Signed-off-by: Krunoslav Kovac Reviewed-by: Aric Cyr Acked-by: Anthony Koo Acked-by: Aurabindo Pillai Signed-off-by: Alex Deucher

drm/amd/display: Convert memory from cpu to fw endianness correctly

2020-04-22T22:11:48Z

[Why] Current code does not guarantee the correct endianness of memory being copied to fw, specifically in the case where cpu isn't little endian. [How] Windows and Diags are always little endian, so we define a macro that does nothing. Linux already defines this macro and will do the correct endianness conversion.

drm/amd/display: Change infopacket type programming

2020-04-22T22:11:47Z

[Why] Certain displays may experience blanking if infopacket max range does not equal nominal refresh rate. [How] Add additional infopacket versions to program range to full or forced range in freesync states. This does not change the vrr logic.

drm/amd/display: Check ramp != NULL before applying lut1d for degamma

2020-04-22T22:11:47Z

[Why] A NULL ramp is a valid configuration for passing into mod_color_calculate_degamma_params but we'll hit a NULL pointer if we do so. We need this in order to get the right transfer function to do degamma on NV12 formats where we aren't supplied with a custom user degamma. [How] Add the NULL check.
