2024-03-07drm/etnaviv: Restore some id valuesChristian Gmeiner
The hwdb selection logic as a feature that allows it to mark some fields as 'don't care'. If we match with such a field we memcpy(..) the current etnaviv_chip_identity into ident. This step can overwrite some id values read from the GPU with the 'don't care' value. Fix this issue by restoring the affected values after the memcpy(..). As this is crucial for user space to know when this feature works as expected increment the minor version too.

2024-03-04drm/msm/dp: enable SDP and SDE periph flush updatePaloma Arellano
DP controller can be setup to operate in either SDP update flush mode or peripheral flush mode based on the DP controller hardware version. Starting in DP v1.2, the hardware documents require the use of peripheral flush mode for SDP packets such as PPS OR VSC SDP packets. In-line with this guidance, lets program the DP controller to use peripheral flush mode starting DP v1.2 Changes in v4: - Clear up that DP_MAINLINK_CTRL_FLUSH_MODE register requires the use of bits [24:23] - Modify macros DP_MAINLINK_FLUSH_MODE_UPDATE_SDP and DP_MAINLINK_FLUSH_MODE_SDP_PERIPH_UPDATE to explicitly set their values in the bits of DP_MAINLINK_CTRL_FLUSH_MODE_MASK Changes in v3: - Clear up that the DP_MAINLINK_FLUSH_MODE_SDE_PERIPH_UPDATE macro is setting bits [24:23] to a value of 3 Changes in v2: - Use the original dp_catalog_hw_revision() function to correctly check the DP HW version Signed-off-by: Paloma Arellano <quic_parellan@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/579621/ Link: https://lore.kernel.org/r/20240222194025.25329-16-quic_parellan@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Modify the output width and height parameters of hw_cdm to utilize the physical encoder's data instead of obtaining the information from the framebuffer.

Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and mode_valid") added a call to drm_atomic_get_new_connector_state() but didn't include drm_atomic.h which defines it. On some configuration, this leads to a build failure, presumably because in the common case the header gets included by an intermediate header but it isn't always the case. Let's add a proper include.

2024-02-29drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flipHsin-Yi Wang
It's possible that mtk_crtc->event is NULL in mtk_drm_crtc_finish_page_flip(). pending_needs_vblank value is set by mtk_crtc->event, but in mtk_drm_crtc_atomic_flush(), it's is not guarded by the same lock in mtk_drm_finish_page_flip(), thus a race condition happens. Consider the following case: CPU1 CPU2 step 1: mtk_drm_crtc_atomic_begin() mtk_crtc->event is not null, step 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !!mtk_crtc->event) step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip: lock mtk_crtc->event set to null, pending_needs_vblank set to false unlock pending_needs_vblank set to true, step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip called again, pending_needs_vblank is still true //null pointer Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more efficient to just check if mtk_crtc->event is null before use.
