2024-02-19drm/msm/mdp5: migrate SMP dumping to using atomic_print_stateDmitry Baryshkov4-49/+15
The Shared Memory Pool (SMP) state is a part of the MDP5's private object state. Use existing infrastructure, atomic_print_state() callback, to dump SMP state (which also makes it included into debugfs/dri/N/state). This allows us to drop the custom debugfs file too.

2024-02-19drm/msm/mdss: generate MDSS data for MDP5 platformsDmitry Baryshkov1-0/+51
Older (mdp5) platforms do not use per-SoC compatible strings. Instead they use a single compat entry 'qcom,mdss'. To facilitate migrating these platforms to the DPU driver provide a way to generate the MDSS / UBWC data at runtime, when the DPU driver asks for it. It is not possible to generate this data structure at the probe time, since some platforms might not have MDP_CLK enabled, which makes reading HW_REV register useless and prone to possible crashes.

Rename meson_encoder_{cvbs,dsi,hdmi}_init() to meson_encoder_{cvbs,dsi,hdmi}_probe() so it's clear that these functions are used at probe time during driver initialization. Also switch all error prints inside those functions to use dev_err_probe() for consistency. This makes the code more straight forward to read and makes the error prints within those functions consistent (by logging all -EPROBE_DEFER with dev_dbg(), while actual errors are logged with dev_err() and get the error value printed).

2024-02-19drm/meson: Don't remove bridges which are created by other driversMartin Blumenstingl3-3/+0
Stop calling drm_bridge_remove() for bridges allocated/managed by other drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}. drm_bridge_remove() unregisters the bridge so it cannot be used anymore. Doing so for bridges we don't own can lead to the video pipeline not being able to come up after -EPROBE_DEFER of the VPU because we're unregistering a bridge that's managed by another driver. The other driver doesn't know that we have unregistered it's bridge and on subsequent .probe() we're not able to find those bridges anymore (since nobody re-creates them). This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

The TBA and TMA, along with an unused IB allocation, reside at low addresses in the VM address space. A stray VM fault which hits these pages must be serviced by making their page table entries invalid. The scheduler depends upon these pages being resident and fails, preventing a debugger from inspecting the failure state. By relocating these pages above 47 bits in the VM address space they can only be reached when bits [63:48] are set to 1. This makes it much less likely for a misbehaving program to generate accesses to them.
