2025-10-28drm/amdkfd: Fix use-after-free of HMM range in svm_range_validate_and_map()Srinivasan Shanmugam
The function svm_range_validate_and_map() was freeing `range` when amdgpu_hmm_range_get_pages() failed. But later, the code still used the same `range` pointer and freed it again. This could cause a use-after-free and double-free issue. The fix sets `range = NULL` right after it is freed and checks for `range` before using or freeing it again. v2: Removed duplicate !r check in the condition for clarity. v3: In amdgpu_hmm_range_get_pages(), when hmm_range_fault() fails, we kvfree(pfns) but leave the pointer in hmm_range->hmm_pfns still pointing to freed memory. The caller (or amdgpu_hmm_range_free(range)) may try to free range->hmm_range.hmm_pfns again, causing a double free, Setting hmm_range->hmm_pfns = NULL immediately after kvfree(pfns) prevents both double free. (Philip) In svm_range_validate_and_map(), When r == 0, it means success → range is not NULL. When r != 0, it means failure → already made range = NULL. So checking both (!r && range) is unnecessary because the moment r == 0, we automatically know range exists and is safe to use.

2025-10-28drm/amdgpu: Convert amdgpu userqueue management from IDR to XArrayJesse.Zhang
This commit refactors the AMDGPU userqueue management subsystem to replace IDR (ID Allocation) with XArray for improved performance, scalability, and maintainability. The changes address several issues with the previous IDR implementation and provide better locking semantics. Key changes: 1. **Global XArray Introduction**: - Added `userq_doorbell_xa` to `struct amdgpu_device` for global queue tracking - Uses doorbell_index as key for efficient global lookup - Replaces the previous `userq_mgr_list` linked list approach 2. **Per-process XArray Conversion**: - Replaced `userq_idr` with `userq_mgr_xa` in `struct amdgpu_userq_mgr` - Maintains per-process queue tracking with queue_id as key - Uses XA_FLAGS_ALLOC for automatic ID allocation 3. **Locking Improvements**: - Removed global `userq_mutex` from `struct amdgpu_device` - Replaced with fine-grained XArray locking using XArray's internal spinlocks 4. **Runtime Idle Check Optimization**: - Updated `amdgpu_runtime_idle_check_userq()` to use xa_empty 5. **Queue Management Functions**: - Converted all IDR operations to equivalent XArray functions: - `idr_alloc()` → `xa_alloc()` - `idr_find()` → `xa_load()` - `idr_remove()` → `xa_erase()` - `idr_for_each()` → `xa_for_each()` Benefits: - **Performance**: XArray provides better scalability for large numbers of queues - **Memory Efficiency**: Reduced memory overhead compared to IDR - **Thread Safety**: Improved locking semantics with XArray's internal spinlocks v2: rename userq_global_xa/userq_xa to userq_doorbell_xa/userq_mgr_xa Remove xa_lock and use its own lock. v3: Set queue->userq_mgr = uq_mgr in amdgpu_userq_create() v4: use xa_store_irq (Christian) hold the read side of the reset lock while creating/destroying queues and the manager data structure.

2025-10-28drm/amd: Re-introduce property to control adaptive backlight modulationMario Limonciello
commit 0887054d14ae ("drm/amd: Drop abm_level property") dropped the abm level property in favor of sysfs control. Since then there have been discussions that compositors showed an interest in modifying a vendor specific property instead. So re-introduce the abm level property, but with different semantics. Rather than being an integer it's now an enum. One of the enum options is 'sysfs', and that is because there is still a sysfs file for use by userspace when the compositor doesn't support this property. If usespace has not modified this property, the default value will be for sysfs to control it. Once userspace has set the property stop allowing sysfs control. The property is only attached to non-OLED eDP panels.

2025-10-28drm/amdgpu: Fix pointer casts when reading dynamic region sizesSrinivasan Shanmugam
The function amdgpu_virt_get_dynamic_data_info() writes a 64-bit size value. In two places (amdgpu_bios.c and amdgpu_discovery.c), the code passed the address of a smaller variable by casting it to u64 *, which is unsafe. This could make the function write more bytes than the smaller variable can hold, possibly overwriting nearby memory. Reported by static analysis tools. v2: Dynamic region size comes from the host (SR-IOV setup) and is always fixed to 5 MB. (Lijo/Ellen) 5 MB easily fits inside a 32-bit value, so using a 64-bit type is not needed. It also avoids extra type casts Fixes: b4a8fcc7826a ("drm/amdgpu: Add logic for VF ipd and VF bios to init from dynamic crit_region offsets") Reported by: Dan Carpenter <dan.carpenter@linaro.org> Cc: Ellen Pan <yunru.pan@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-10-28drm/amdgpu: Make SR-IOV critical region checks overflow-safeSrinivasan Shanmugam
The function amdgpu_virt_init_critical_region() contained an invalid check for a negative init_hdr_offset value: if (init_hdr_offset < 0) Since init_hdr_offset is an unsigned 32-bit integer, this condition can never be true and triggers a Smatch warning: warn: unsigned 'init_hdr_offset' is never less than zero In addition, the subsequent bounds check: if ((init_hdr_offset + init_hdr_size) > vram_size) was vulnerable to integer overflow when adding the two unsigned values. Thus, by promoting offset and size to 64-bit and using check_add_overflow() to safely validate the sum against VRAM size.
