This function consumes a lot of stack space and it blows up the size of dml30_ModeSupportAndSystemConfigurationFull() with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated. Commit a0f7e7f7 ("drm/amd/display: fix i386 frame size warning") aimed to address this for i386 but it did not help x86_64. To reduce the amount of stack space that dml30_ModeSupportAndSystemConfigurationFull() uses, mark UseMinimumDCFCLK() as noinline, using the _for_stack variant for documentation. While this will increase the total amount of stack usage between the two functions (1632 and 1304 bytes respectively), it will make sure both stay below the limit of 2048 bytes for these files. The aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage so it should not be reverted in favor of this change.

[Why] For HDR mode, we get total 512 tf_point and after switching to SDR mode we actually get 400 tf_point and the rest of points(401~512) still use dirty value from HDR mode. We should limit the rest of the points to max value. [How] Limit the value when coordinates_x.x > 1, just like what we do in translate_from_linear_space for other re-gamma build paths. Tested-by:

Due to lack of this functionality, reducing the max cursor size is the only way to ensure that power savings of Subview port feature is utilized for asics that support it.

Enabling panfrost GPU OPP with dynamic regulator will make OPP responsible to enable and configure it. Unfortunately OPP configure and enable the regulator when an OPP is asked to be set, which is not the case during panfrost_devfreq_init(). This leave the regulator unconfigured and if no GPU load is triggered, no OPP is asked to be set which make the regulator framework switching it off during regulator_late_cleanup() without noticing and therefore make the board hang as any access to GPU memory space make bus locks up. Call dev_pm_opp_set_opp() with the recommend OPP in panfrost_devfreq_init() to enable the regulator, this will properly configure and enable the regulator and will avoid any switch off by regulator_late_cleanup().

A lot of modern laptops use the Parade PS8461E MUX for eDP switching. The MUX can operate in jitter cleaning mode or redriver mode, the first one resulting in higher link quality. The jitter cleaning mode needs to know the link rate used and the MUX achieves this by snooping the LINK_BW_SET, LINK_RATE_SELECT and SUPPORTED_LINK_RATES DPCD accesses. When the MUX is powered down (seems this can happen whenever the display is turned off) it loses track of the snooped link rates so when we do the LINK_RATE_SELECT write it no longer knowns which link rate we're selecting, and thus it falls back to the lower quality redriver mode. This results in unstable high link rates (eg. usually 8.1Gbps link rate no longer works correctly). In order to avoid all that let's re-snoop SUPPORTED_LINK_RATES from the sink at the start of every link training. Unfortunately we don't have a way to detect the presence of the MUX. It looks like the set of laptops equipped with this MUX is fairly large and contains devices from multiple manufacturers. It may also still be growing with new models. So a quirk doesn't seem like a very easily maintainable option, thus we shall attempt to do this unconditionally on all machines that use LINK_RATE_SELECT. Hopefully this extra DPCD read doesn't cause issues for any unaffected machine. If that turns out to be the case we'll need to convert this into a quirk in the future.
