2021-12-13drm/msm/a6xx: Skip crashdumper state if GPU needs_hw_initRob Clark2-2/+8
I am seeing some crash logs which imply that we are trying to use crashdumper hw to read back GPU state when the GPU isn't initialized. This doesn't go well (for example, GPU could be in 32b address mode and ignoring the upper bits of buffer that it is trying to dump state to). I'm not *quite* sure how we get into this state in the first place, but lets not make a bad situation worse by triggering iova fault crashes. While we're at it, also add the information about whether the GPU is initialized to the devcore dump to make this easier to see in the logs (which makes the WARN_ON() redundant and even harmful because it fills up the small bit of dmesg we get with the crash report).

Commit 739b4e7756d3 ("drm/msm/dsi: Fix an error code in msm_dsi_modeset_init()") changed msm_dsi_modeset_init() to return an error code in case msm_dsi_manager_validate_current_config() returns false. However this is not an error case, but a slave DSI of the bonded DSI link. In this case msm_dsi_modeset_init() should return 0, but just skip connector and bridge initialization. To reduce possible confusion, drop the msm_dsi_manager_validate_current_config() function, and specif 'bonded && !master' condition directly in the msm_dsi_modeset_init().

2021-12-07drm/msm/gpu: Don't allow zero fence_idRob Clark1-1/+1
Elsewhere we treat zero as "no fence" and __msm_gem_submit_destroy() skips removal from fence_idr. We could alternately change this to use negative values for "no fence" but I think it is more clear to not allow zero as a valid fence_id.

2021-12-06drm/msm: Initialize MDSS irq domain at probe timeDmitry Baryshkov4-62/+59
Since commit 8f59ee9a570c ("drm/msm/dsi: Adjust probe order"), the DSI host gets initialized earlier, but this caused unability to probe the entire stack of components because they all depend on interrupts coming from the main `mdss` node (mdp5, or dpu1). To fix this issue, move mdss device initialization (which include irq domain setup) to msm_mdev_probe() time, as to make sure that the interrupt controller is available before dsi and/or other components try to initialize, finally satisfying the dependency.

2021-12-06drm/msm: Allocate msm_drm_private early and pass it as driver dataAngeloGioacchino Del Regno7-56/+36
In preparation for registering the mdss interrupt controller earlier, move the allocation of msm_drm_private from component bind time to msm_drv probe; this also allows us to use the devm variant of kzalloc. Since it is not right to allocate the drm_device at probe time (as it should exist only when all components are bound, and taken down when components get cleaned up), the only way to make this happen is to pass a pointer to msm_drm_private as driver data (like done in many other DRM drivers), instead of one to drm_device like it's currently done in this driver. This is also simplifying some bind/unbind functions around drm/msm, as some of them are using drm_device just to grab a pointer to the msm_drm_private structure, which we now retrieve in one call.
