It's doing the same thing dpu_plane_enabled() is. Changes in v2: - None Reviewed-by:

Sean Paul authored
dpu_plane_atomic_check() is a very thin wrapper around dpu_plane_sspp_atomic_check(). All it does is a NULL-check of state->fb, which is already done by drm_atomic_helper_check_plane_state(). Further, the helper sets state->visible = false when this is true. So remove dpu_plane_atomic_check() and just use dpu_plane_sspp_atomic_check() directly.

src/dst rects are checked in both atomic_check and atomic_update, with the more comprehensive check occurring in atomic_update, which is backwards. So consolodate the checks in atomic_check.

RM maintained a redundant definition for display topology to identify the no. of hw blocks needed for a display and their hardware dependencies. This information can be implicitly deduced from the msm_display_topology structure available in RM reserve request. In addition to getting rid of the redundant topology, this change also removes the topology name enums and their usages. changes in v4: - remove the topology name enum entirely (Sean) changes in v5: - remove RM topology definition and their references (Sean) - Implement helper for dual mixer CRTC (Sean) changes in v6: - avoid heap memory for topology (Sean) Signed-off-by:

In virtual encoder modeset, DPU makes RM request to assign hw blocks for the display. It is also expected in modeset to iterate and associate the physical encoders with their relevant hw blocks.

The MDSS device is created before the MSM driver attempts to bind the sub components. If any of the components return -EPROBE_DEFER the MDSS device is destroyed and tried again later. If this happens the dpu_mdss_isr interrupt created from the DPU MDSS is not freed when the MDSS device is destroyed and has a risk of triggering later and hitting a fault by accessing a mmio region that no longer exists. Even if the interrupt isn't triggered by accident when the device attempts to reprobe it would error out when it tries to re-register the interrupt so unconditionally removing it in the destroy is the right move. Switch the device managed dpu_mdss_isr to be unmanaged and add a free_irq() in the mdss destroy function. Reviewed-by:

The atomic_check is a bit too aggressive with respect to planes which leave the active area. This caused a bunch of log spew when the cursor got to the edge of the screen and stopped it from going all the way. This patch removes the conservative bounds checks from atomic and clips the dst rect such that we properly display planes which go off the screen.

That corresponds to the integer 16. That is then indexed into drm_encoder_enum_list in drm_encoder_init() to look up the name of the encoder. If you're still following along, that's an encoder not a connector! We really want to use DRM_MODE_ENCODER_DSI (integer 6) instead of DRM_MODE_CONNECTOR_DSI here, or we'll go out of bounds of the encoder array. Pass the right thing and everything is fine.

Currently msm_dsi->id is initialized to 0 during kzalloc. If bind fails for a secondary dsi device before its id can be properly set (such as during dt parsing), the id will point to the primary dsi device, causing its reference to be removed from dsi_manager's global (msm_dsim_glb) array. This patch initializes the id to -1 and checks for negative in the manager cleanup. Cc: Doug Anderson <dianders@chromium.org> Reviewed-by:
