When CONFIG_FONTS ("Select compiled-in fonts") is not enabled, the user should not be asked about any fonts. However, when CONFIG_DRM_PANIC is enabled, the user is still asked about the Sparc console 12x22 and Terminus 16x32 fonts. Fix this by moving the "|| DRM_PANIC" to where it belongs. Split the dependency in two rules to improve readability. Fixes: b94605a3 ("lib/fonts: Allow to select fonts for drm_panic") Signed-off-by: -

No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill in the optional drm_scanout_buffer.set_pixel() member. Hence the member may contain non-zero garbage, causing a crash when deferencing it during drm panic. Fix this by pre-initializing the drm_scanout_buffer object before calling drm_plane_helper_funcs.get_scanout_buffer().

BOs in a bulk move have to share the same reservation object. That is not the case in the ttm_bo_unreserve_bulk subtest.

With new connector model, tc358767 will not create the connector, when DRM_BRIDGE_ATTACH_NO_CONNECTOR is set and display-controller driver will rely on format negotiation to setup the encoder format. Add the missing bus format negotiation hooks in the drm_bridge_funcs to complete DRM_BRIDGE_ATTACH_NO_CONNECTOR support. Output format, for DPI/DSI to DP, is selected to MEDIA_BUS_FMT_RGB888_1X24 as default, keeping in mind what the older model used to support. Reported-by:

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.

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:
