This reverts commit 8ebb1fc2. The panel should be handled through the samsung-atna33xc20 driver for correct power up timings. Otherwise the backlight does not work correctly. We have existing users of this panel through the generic "edp-panel" compatible (e.g. the Qualcomm X1E80100 CRD), but the screen works only partially in that configuration: It works after boot but once the screen gets disabled it does not turn on again until after reboot. It behaves the same way with the default "conservative" timings, so we might as well drop the configuration from the panel-edp driver. That way, users with old DTBs will get a warning and can move to the new driver. Reviewed-by:

Having a limit of 64 DRM devices is not good enough for modern world where we have multi-GPU servers, SR-IOV virtual functions and virtual devices used for testing. Let's utilize full minor range for DRM devices. To avoid regressing the existing userspace, we're still maintaining the numbering scheme where 0-63 is used for primary, 64-127 is reserved (formerly for control) and 128-191 is used for render. For minors >= 192, we're allocating minors dynamically on a first-come, first-served basis. Signed-off-by:

Accel minor management is based on DRM (and is also using struct drm_minor internally), since DRM is using XArray for minors, it makes sense to also convert accel. As the two implementations are identical (only difference being the underlying xarray), move the accel_minor_* functionality to DRM. Signed-off-by:

Michał Winiarski authored
IDR is deprecated, and since XArray manages its own state with internal locking, it simplifies the locking on DRM side. Additionally, don't use the IRQ-safe variant, since operating on drm minor is not done in IRQ context. Suggested-by:

Ideally, we want to drop the legacy vblank enable for older ASICs. This should be possible now, since we can now specify how many frames we need to wait before disabling vblanking instead of being forced to either choose between no delay (which can still be buggy) and drm_vblank_offdelay (which is much longer by default than is required on AMD hardware).

Hook up drm_crtc_vblank_on_config() in amdgpu_dm. So, that we can enable PSR and other static screen optimizations more quickly, while avoiding stuttering issues that are accompanied by the following dmesg error: [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3 This also allows us to mimic how vblanking is handled by the Windows amdgpu driver. Specifically, we wait two idle frames before disabling the vblank timer there. Reviewed-by:

This patch adds a new panic screen, with a QR code and the kmsg data embedded. If DRM_PANIC_SCREEN_QR_CODE_URL is set, then the kmsg data will be compressed with zlib and encoded as a numerical segment, and appended to the URL as a URL parameter. This allows to save space, and put about ~7500 bytes of kmsg data, in a V40 QR code. Linux distributions can customize the URL, and put a web frontend to directly open a bug report with the kmsg data. Otherwise the kmsg data will be encoded as a binary segment (ie raw ascii) and only a maximum of 2953 bytes of kmsg data will be available in the QR code. You can also limit the QR code size with DRM_PANIC_SCREEN_QR_VERSION. Signed-off-by:

The commit 0f525133 ("drm/vc4: hdmi: Make sure the controller is powered in detect") introduced the necessary power management handling to avoid register access while controller is powered down. Unfortunately it just print a warning if pm_runtime_resume_and_get() fails and proceed anyway. This could happen during suspend to idle. So we must assume it is unsafe to access the HDMI register. So bail out properly. Fixes: 0f525133 ("drm/vc4: hdmi: Make sure the controller is powered in detect") Signed-off-by:

Ast's BMC connector tracks the status of an underlying physical connector and updates the BMC status accordingly. This functionality works around GNOME's settings app, which cannot handle multiple outputs on the same CRTC.

Hence, remove the driver's code and the BMC output entirely. v3: - remove struct ast_bmc_connector Signed-off-by:
