2025-05-12drm/msm/dpu: Add missing "fetch" name to set_active_pipes()Krzysztof Kozlowski
The set_active_pipes() callback configures CTL_FETCH_PIPE_ACTIVE and newer DPU v12.0 comes with CTL_PIPE_ACTIVE, thus rename it to set_active_fetch_pipes() to better match the purpose.

The HDMI driver already has msm_hdmi_hpd_enable() and msm_hdmi_hpd_disable() functions. Wire them into the msm_hdmi_bridge_funcs, so that HPD can be enabled and disabled dynamically rather than always having HPD events generation enabled.

2025-05-12drm/tiny: panel-mipi-dbi: Use drm_client_setup_with_fourcc()Fabio Estevam
Since commit 559358282e5b ("drm/fb-helper: Don't use the preferred depth for the BPP default"), RGB565 displays such as the CFAF240320X no longer render correctly: colors are distorted and the content is shown twice horizontally. This regression is due to the fbdev emulation layer defaulting to 32 bits per pixel, whereas the display expects 16 bpp (RGB565). As a result, the framebuffer data is incorrectly interpreted by the panel. Fix the issue by calling drm_client_setup_with_fourcc() with a format explicitly selected based on the display's bits-per-pixel value. For 16 bpp, use DRM_FORMAT_RGB565; for other values, fall back to the previous behavior. This ensures that the allocated framebuffer format matches the hardware expectations, avoiding color and layout corruption. Tested on a CFAF240320X display with an RGB565 configuration, confirming correct colors and layout after applying this patch.

2025-05-10drm/msm/adreno: Remove MODULE_FIRMWARE()'sRob Clark
The driver handles the case where gpu fw is not in the initrd. OTOH it doesn't always handle the case where _some_ fw is in the initrd, but others are not. In particular the zap fw tends to be signed with an OEM specific key, so the paths/names differ across devices with the same SoC/GPU, so we cannot sanely list them with MODULE_FIRMWARE(). So MODULE_FIRMWARE() just ends up causing problems without actually solving anything. Remove them!

2025-05-09drm/i915/dp: Fix determining SST/MST mode during MTP TU state computationImre Deak
Determining the SST/MST mode during state computation must be done based on the output type stored in the CRTC state, which in turn is set once based on the modeset connector's SST vs. MST type and will not change as long as the connector is using the CRTC. OTOH the MST mode indicated by the given connector's intel_dp::is_mst flag can change independently of the above output type, based on what sink is at any moment plugged to the connector. Fix the state computation accordingly.

The amdgpu_set_thermal_throttling_logging() function directly accesses the ratelimit_state structure's ->missed field, which works, but which also makes it more difficult to change this field. Therefore, make use of the ratelimit_state_reset_interval() function instead of directly accessing the ->missed field. Nevertheless, open-coded use of ->burst and ->interval is still permitted, for example, for runtime sysfs adjustment of these fields.

2025-05-08drm/xe/gsc: do not flush the GSC worker from the reset pathDaniele Ceraolo Spurio
The workqueue used for the reset worker is marked as WQ_MEM_RECLAIM, while the GSC one isn't (and can't be as we need to do memory allocations in the gsc worker). Therefore, we can't flush the latter from the former. The reason why we had such a flush was to avoid interrupting either the GSC FW load or in progress GSC proxy operations. GSC proxy operations fall into 2 categories: 1) GSC proxy init: this only happens once immediately after GSC FW load and does not support being interrupted. The only way to recover from an interruption of the proxy init is to do an FLR and re-load the GSC. 2) GSC proxy request: this can happen in response to a request that the driver sends to the GSC. If this is interrupted, the GSC FW will timeout and the driver request will be failed, but overall the GSC will keep working fine. Flushing the work allowed us to avoid interruption in both cases (unless the hang came from the GSC engine itself, in which case we're toast anyway). However, a failure on a proxy request is tolerable if we're in a scenario where we're triggering a GT reset (i.e., something is already gone pretty wrong), so what we really need to avoid is interrupting the init flow, which we can do by polling on the register that reports when the proxy init is complete (as that ensure us that all the load and init operations have been completed). Note that during suspend we still want to do a flush of the worker to make sure it completes any operations involving the HW before the power is cut. v2: fix spelling in commit msg, rename waiter function (Julia) Fixes: dd0e89e5edc2 ("drm/xe/gsc: GSC FW load") Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4830 Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Cc: <stable@vger.kernel.org> # v6.8+ Reviewed-by: Julia Filipchuk <julia.filipchuk@intel.com> Link: https://lore.kernel.org/r/20250502155104.2201469-1-daniele.ceraolospurio@intel.com (cherry picked from commit 12370bfcc4f0bdf70279ec5b570eb298963422b5) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
