2024-02-11drm/msm/dpu: improve DSC allocationKuogee Hsieh1-15/+139
At DSC V1.1 DCE (Display Compression Engine) contains a DSC encoder. However, at DSC V1.2 DCE consists of two DSC encoders, one has an odd index and another one has an even index. Each encoder can work independently. But only two DSC encoders from same DCE can be paired to work together to support DSC merge mode at DSC V1.2. For DSC V1.1 two consecutive DSC encoders (start with even index) have to be paired to support DSC merge mode. In addition, the DSC with even index have to be mapped to even PINGPONG index and DSC with odd index have to be mapped to odd PINGPONG index at its data path in regardless of DSC V1.1 or V1.2. This patch improves DSC allocation mechanism with consideration of those factors. Changes in V6: -- rename _dpu_rm_reserve_dsc_single to _dpu_rm_dsc_alloc -- rename _dpu_rm_reserve_dsc_pair to _dpu_rm_dsc_alloc_pair -- pass global_state to _dpu_rm_pingpong_next_index() -- remove pp_max -- fix for loop condition check at _dpu_rm_dsc_alloc() Changes in V5: -- delete dsc_id[] -- update to global_state->dsc_to_enc_id[] directly -- replace ndx with idx -- fix indentation at function declaration -- only one for loop at _dpu_rm_reserve_dsc_single() Changes in V4: -- rework commit message -- use reserved_by_other() -- add _dpu_rm_pingpong_next_index() -- revise _dpu_rm_pingpong_dsc_check() Changes in V3: -- add dpu_rm_pingpong_dsc_check() -- for pair allocation use i += 2 at for loop Changes in V2: -- split _dpu_rm_reserve_dsc() into _dpu_rm_reserve_dsc_single() and _dpu_rm_reserve_dsc_pair() Fixes: f2803ee91a41 ("drm/msm/disp/dpu1: Add DSC support in RM") Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/572144/ Link: https://lore.kernel.org/r/1702580172-30606-1-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Since the commit 8b03ad30e314 ("drm/msm/dsi: Use one connector for dual DSI mode"), the second DSI host in the bonded pair will not be associated with the encoder and will not get the bridges, thus making condition in msm_dsi_manager_set_split_display() always false.

2024-02-11drm/msm/dsi: drop msm_dsi_device_connected() functionDmitry Baryshkov2-11/+0
Since the commit 8f59ee9a570c ("drm/msm/dsi: Adjust probe order") the DSI hosts are not bound through the component framework if the DSI driver wasn't attached to the DSI device connected to this host. Afterwards, if there is no bridge (including the panel bridge) created for the DSI device then devm_drm_of_get_bridge() will return an error, also making msm_dsi_manager_ext_bridge_init() and thus DSI modesetting init fail. This way there can be no 'unconnected' MSM DSI bridges. Remove the msm_dsi_device_connected() function.

2024-02-11drm/msm/dsi: do not store internal bridge pointerDmitry Baryshkov3-19/+15
Since the driver was switched to devm_drm_bridge_add(), there is no need anymore to store the created bridge instance in struct msm_dsi. Drop this field and pass data directly.

2024-02-07drm: xlnx: zynqmp_dpsub: Filter interrupts against maskAnatoliy Klymenko1-1/+8
Filter out status register against the interrupts' mask. Some events are being reported via DP status register, even if corresponding interrupts have been disabled. One instance of such event leads to generation of VBLANK when the driver is in DRM bridge mode, which in turn results in NULL pointer dereferencing. We should avoid processing such events in an interrupt handler context. This problem is less noticeable when the driver operates in DMA mode, as in this case we have DRM CRTC object instantiated and DRM framework simply discards unwanted VBLANKs in drm_handle_vblank().
