Multiplier to 'gain' the plane. When PQ is decoded using the fixed func transfer function to the internal FP16 fb, 1.0 -> 80 nits (on AMD at least) When sRGB is decoded, 1.0 -> 1.0. Therefore, 1.0 multiplier = 80 nits for SDR content. So if you want, 203 nits for SDR content, pass in (203.0 / 80.0). v4: - comment about the PQ TF need for L-to-NL (from Harry's review) Reviewed-by:

When screen brightness is rapidly changed and PSR-SU is enabled the display hangs on panels with this TCON even on the latest DCN 3.1.4 microcode (0x8002a81 at this time). This was disabled previously as commit 072030b1 ("drm/amd: Disable PSR-SU on Parade 0803 TCON") but reverted as commit 1e66a17c ("Revert "drm/amd: Disable PSR-SU on Parade 0803 TCON"") in favor of testing for a new enough microcode (commit cd2e31a9 ("drm/amd/display: Set minimum requirement for using PSR-SU on Phoenix")). As hangs are still happening specifically with this TCON, disable PSR-SU again for it until it can be root caused.

[Description] - When we're in a no plane config, DCN is always asserting P-State allow - This creates a scenario where the P-State blackout can start just as VUPDATE takes place and transitions the DCN config to a one where one or more HUBP's are active which can result in underflow - To fix this issue, force p-state disallow and unforce after the transition from no planes case -> one or more planes active Reviewed-by:

[Description] For mode programming we want to extend the prefetch as much as possible (up to oto, or as long as we can for equ) if we're not already applying the 60us prefetch requirement. This is to avoid intermittent underflow issues during prefetch. The prefetch extension is applied under the following scenarios: 1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank) 2. We're using subvp or drr methods of p-state switch, in which case we we don't care if prefetch takes up more of the blanking time Mode programming typically chooses the smallest prefetch time possible (i.e. highest bandwidth during prefetch) presumably to create margin between p-states / c-states that happen in vblank and prefetch. Therefore we only apply this prefetch extension when p-state in vblank is not required (UCLK p-states take up the most vblank time). Reviewed-by:

Hook up driver-specific atomic operations for managing AMD color properties. Create AMD driver-specific color management properties and attach them according to HW capabilities defined by `struct dc_color_caps`. First add plane degamma LUT properties that means user-blob and its size. We will add more plane color properties in the next patches. In addition, we define AMD_PRIVATE_COLOR to guard these driver-specific plane properties. Plane degamma can be used to linearize input space for arithmetical operations that are more accurate when applied in linear color. v2: - update degamma LUT prop description - move private color operations from amdgpu_display to amdgpu_dm_color v5: - get degamma blob correctly (Joshua) Reviewed-by:

Merge tag 'exynos-drm-next-for-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next One bug fix - Add a missing call to drm_atomic_helper_shutdown() in Exynos DRM driver. This function is necessary during system shutdown and when the driver is unbound. Without this function, components like panels may not shut down properly, potentially leading to power issue as mentioned in the kernel documentation, specially in the "driver instance overview" secstion of 'drm_drv.c'. Two cleanups - Convert '.remove()' callback function in the Exynos DRM platform driver to a version that returns void instead of an integer. - Change connector type of exynos_drm_dpi.c module to DPI.

When exynos_drm_dpi.c was written, DRM_MODE_CONNECTOR_DPI did not exist yet and I guess that's the reason why DRM_MODE_CONNECTOR_VGA was used as the connector type. However, now it makes more sense to use DRM_MODE_CONNECTOR_DPI as the connector type. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time and at driver unbind time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart and at driver remove (or unbind) time comes straight out of the kernel doc "driver instance overview" in drm_drv.c. A few notes about this fix: - When adding drm_atomic_helper_shutdown() to the unbind path, I added it after drm_kms_helper_poll_fini() since that's when other drivers seemed to have it. - Technically with a previous patch, ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop"), we don't actually need to check to see if our "drm" pointer is NULL before calling drm_atomic_helper_shutdown(). We'll leave the "if" test in, though, so that this patch can land without any dependencies. It could potentially be removed later. - This patch also makes sure to set the drvdata to NULL in the case of bind errors to make sure that shutdown can't access freed data.
