ttm page fault handler ttm_bo_vm_fault_reserved() maps TTM_BO_VM_NUM_PREFAULT more pages beforehand due to the principle of locality. However, on some platform the page faults are more costly, this patch intends to increase the number of ttm pre-fault to relieve the number of page faults. When multiple levels of page table is supported, the new default value would be the PMD size, similar to huge page. Signed-off-by:

PREEMPT_RT has a different locking implementation for ww_mutex. The base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex' for PREEMPT_RT builds. Using mutex_lock() directly on the base mutex in ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT. The locking-selftest has its own defines to deal with this and it is probably best to defines the needed one within the test program since their usefulness is limited outside of well known selftests. Provide ww_mutex_base_lock() which points to the correct function for PREEMPT_RT and non-PREEMPT_RT builds. Fixes: 995279d2 ("drm/ttm/tests: Add tests for ttm_bo functions") Signed-off-by:

dma_heap_allocation_data defines the UAPI as follows: struct dma_heap_allocation_data { __u64 len; __u32 fd; __u32 fd_flags; __u64 heap_flags; }; But dma heaps are casting both fd_flags and heap_flags into unsigned long.

simple_bridge_probe() calls drm_bridge_add() Thus, drm_bridge_remove() must be called in the remove() callback. If we call devm_drm_bridge_add() instead, then drm_bridge_remove() will be called automatically at device release, and the remove() callback is no longer required. Signed-off-by:

The race condition between fbcon and drm_panic can only occurs if VT_CONSOLE is set. So update drm_panic dependency accordingly. This will make it easier for Linux distributions to enable drm_panic by disabling VT_CONSOLE, and keeping fbcon terminal. The only drawback is that fbcon won't display the boot kmsg, so it should rely on userspace to do that. At least plymouth already handle this case with https://gitlab.freedesktop.org/plymouth/plymouth/-/merge_requests/224Suggested-by:

drm_encoder_cleanup is responsible for calling drm_bridge_detach for each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn responsible for unregistering the AUX bus. However, we never ended up calling drm_encoder_cleanup in the remove or error paths, so the AUX bus would stick around after the rest of the driver had been removed. I don't really understand why drm_mode_config_cleanup doesn't call drm_encoder_cleanup for us. It will call destroy (which for simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's encoder_list. Should drm_encoder_cleanup get called before or after drm_atomic_helper_shutdown?

Unconditionally enable the DPSUB layer in the corresponding atomic plane update callback. Setting the new display mode may require disabling and re-enabling the CRTC. This effectively resets DPSUB to the default state with all layers disabled. The original implementation of the plane atomic update enables the corresponding DPSUB layer only if the framebuffer format has changed. This would leave the layer disabled after switching to a different display mode with the same framebuffer format. Signed-off-by:

When host system is under heavy load and the NPU is already running on the lowest frequency, PUNIT may request Duty Cycle Throttling (DCT). This will further reduce NPU power usage. PUNIT requests DCT mode using Survabilty IRQ and mailbox register. The driver then issues a JSM message to the FW that enables the DCT mode. If the NPU resets while in DCT mode, the driver request DCT mode during FW boot. Also add debugfs "dct" file that allows to set arbitrary DCT percentage, which is used by driver tests. Signed-off-by:
