Due to condition in dpu_rm_reserve_sspp, RGB SSPPs are only tried when scaling is requested, which prevents those SSPPs from being reserved if we don't need scaling at all. Instead we should check if YUV support is requested, since scaling on RGB SSPPs is optional and is not implemented in driver yet.

2025-10-29drm/msm: dsi: fix PLL init in bonded modeNeil Armstrong
When in bonded DSI mode, only one PLL in one DSI PHY is used for both DSI PHYs, meaning that parents of the secondary DSI PHY will use the primary DSI PHY PLL as parent. In this case the primary DSI PHY PLL will be set even if the primary DSI PHY is not yet enabled. The DSI PHY code has support for this particular use-case and will handle the fact the PLL was already set when initializing the primary DSI PHY. By introducing a protected variable pll_enable_cnt in the commit cb55f39bf7b1 ("drm/msm/dsi/phy: Fix reading zero as PLL rates when unprepared"), this variable is only initially set to 1 when the DSI PHY is initialized making it impossible to set the PLL before, breaking the bonded DSI use case by returning 0 when setting the PLL from the secondary DSI PHY driver and skipping the correct clocks initialization. But since it was already possible to set the PLL without enabling the DSI PHY, just drop the pll_enable_cnt setting from the PHY enable/disable and simply increment/decrement the pll_enable_cnt variable from the dsi_pll_enable/disable_pll_bias to make sure any PLL operation is done with the PLL BIAS enabled.

2025-10-28drm/amd/display: Don't program BLNDGAM_MEM_PWR_FORCE when CM low-power is ↵Matthew Schwartz
disabled on DCN30 Before commit 33056a97ae5e ("drm/amd/display: Remove double checks for `debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL) checked the low-power debug flag before calling dpp3_power_on_blnd_lut(false). After commit 33056a97ae5e ("drm/amd/display: Remove double checks for `debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL) unconditionally calls dpp3_power_on_blnd_lut(false). The BLNDGAM power helper writes BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled, causing immediate SRAM power toggles instead of deferring at vupdate. This can disrupt atomic color/LUT sequencing during transitions between direct scanout and composition within gamescope's DRM backend on Steam Deck OLED. To fix this, leave the BLNDGAM power state unchanged when low-power is disabled, matching dpp3_power_on_hdr3dlut and dpp3_power_on_shaper.

2025-10-28drm/amd: Check that VPE has reached DPM0 in idle handlerMario Limonciello
[Why] Newer VPE microcode has functionality that will decrease DPM level only when a workload has run for 2 or more seconds. If VPE is turned off before this DPM decrease and the PMFW doesn't reset it when power gating VPE, the SOC can get stuck with a higher DPM level. This can happen from amdgpu's ring buffer test because it's a short quick workload for VPE and VPE is turned off after 1s. [How] In idle handler besides checking fences are drained check PMFW version to determine if it will reset DPM when power gating VPE. If PMFW will not do this, then check VPE DPM level. If it is not DPM0 reschedule delayed work again until it is. v2: squash in return fix (Alex) Cc: Peyton.Lee@amd.com Reported-by: Sultan Alsawaf <sultan@kerneltoast.com> Reviewed-by: Sultan Alsawaf <sultan@kerneltoast.com> Tested-by: Sultan Alsawaf <sultan@kerneltoast.com> Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4615 Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 3ac635367eb589bee8edcc722f812a89970e14b7) Cc: stable@vger.kernel.org
2025-10-28drm/mediatek: Fix device use-after-free on unbindJohan Hovold
A recent change fixed device reference leaks when looking up drm platform device driver data during bind() but failed to remove a partial fix which had been added by commit 80805b62ea5b ("drm/mediatek: Fix kobject put for component sub-drivers"). This results in a reference imbalance on component bind() failures and on unbind() which could lead to a user-after-free. Make sure to only drop the references after retrieving the driver data by effectively reverting the previous partial fix. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
