2025-02-13drm: writeback: Fix use after free in drm_writeback_connector_cleanup()Dan Carpenter

2025-02-13LoongArch: KVM: Set host with kernel mode when switch to VM modeBibo Mao
PRMD register is only meaningful on the beginning stage of exception entry, and it is overwritten with nested irq or exception. When CPU runs in VM mode, interrupt need be enabled on host. And the mode for host had better be kernel mode rather than random or user mode. When VM is running, the running mode with top command comes from CRMD register, and running mode should be kernel mode since kernel function is executing with perf command.

2025-02-13LoongArch: Remove the deprecated notifier hook mechanismYuli Wang
The notifier hook mechanism in proc and cpuinfo is actually unnecessary for LoongArch because it's not used anywhere. It was originally added to the MIPS code in commit d6d3c9afaab4 ("MIPS: MT: proc: Add support for printing VPE and TC ids"), and LoongArch then inherited it. But as the kernel code stands now, this notifier hook mechanism doesn't really make sense for either LoongArch or MIPS. In addition, the seq_file forward declaration needs to be moved to its proper place, as only the show_ipi_list() function in smp.c requires it.

2025-02-13LoongArch: Fix idle VS timer enqueueMarco Crivellari
LoongArch re-enables interrupts on its idle routine and performs a TIF_NEED_RESCHED check afterwards before putting the CPU to sleep. The IRQs firing between the check and the idle instruction may set the TIF_NEED_RESCHED flag. In order to deal with such a race, IRQs interrupting __arch_cpu_idle() rollback their return address to the beginning of __arch_cpu_idle() so that TIF_NEED_RESCHED is checked again before going back to sleep. However idle IRQs can also queue timers that may require a tick reprogramming through a new generic idle loop iteration but those timers would go unnoticed here because __arch_cpu_idle() only checks TIF_NEED_RESCHED. It doesn't check for pending timers. Fix this with fast-forwarding idle IRQs return address to the end of the idle routine instead of the beginning, so that the generic idle loop can handle both TIF_NEED_RESCHED and pending timers.

2025-02-12drm/amdgpu/mes: Add cleaner shader fence address handling in MES for GFX12Alex Deucher
This commit introduces enhancements to the handling of the cleaner shader fence in the AMDGPU MES driver: - The MES (Microcode Execution Scheduler) now sends a PM4 packet to the KIQ (Kernel Interface Queue) to request the cleaner shader, ensuring that requests are handled in a controlled manner and avoiding the race conditions. - The CP (Compute Processor) firmware has been updated to use a private bus for accessing specific registers, avoiding unnecessary operations that could lead to issues in VF (Virtual Function) mode. - The cleaner shader fence memory address is now set correctly in the `mes_set_hw_res_pkt` structure, allowing for proper synchronization of the cleaner shader execution.

2025-02-12drm/amdgpu/mes: Add cleaner shader fence address handling in MES for GFX11Srinivasan Shanmugam
This commit introduces enhancements to the handling of the cleaner shader fence in the AMDGPU MES driver: - The MES (Microcode Execution Scheduler) now sends a PM4 packet to the KIQ (Kernel Interface Queue) to request the cleaner shader, ensuring that requests are handled in a controlled manner and avoiding the race conditions. - The CP (Compute Processor) firmware has been updated to use a private bus for accessing specific registers, avoiding unnecessary operations that could lead to issues in VF (Virtual Function) mode. - The cleaner shader fence memory address is now set correctly in the `mes_set_hw_res_pkt` structure, allowing for proper synchronization of the cleaner shader execution.

2025-02-12drm/amdgpu: Unlocked unmap only clear page table leavesPhilip Yang
SVM migration unmap pages from GPU and then update mapping to GPU to recover page fault. Currently unmap clears the PDE entry for range length >= huge page and free PTB bo, update mapping to alloc new PT bo. There is race bug that the freed entry bo maybe still on the pt_free list, reused when updating mapping and then freed, leave invalid PDE entry and cause GPU page fault. By setting the update to clear only one PDE entry or clear PTB, to avoid unmap to free PTE bo. This fixes the race bug and improve the unmap and map to GPU performance. Update mapping to huge page will still free the PTB bo. With this change, the vm->pt_freed list and work is not needed. Add WARN_ON(unlocked) in amdgpu_vm_pt_free_dfs to catch if unmap to free the PTB.
