2025-10-28drm/amdkfd: Dequeue user queues when process mm releasedPhilip Yang
Move dequeue user queues and destroy user queues from kfd_process_wq_release to mmu notifier release callback, to ensure no system memory access from GPU because the process memory is going to free from CPU after mmu release notifier callback returns. Destroy queue releases the svm prange queue_refcount, this also removes fake flase positive warning message "Freeing queue vital buffer" message if application crash or killed.

2025-10-28drm/amd/display: Determine DVI-I connector type (v2)Timur Kristóf
DC determines the DRM connector type based on the signal type, which becomes problematic when a connector may support different signal types, such as DVI-I. With this patch, it is now determined according to the actual connector type for DVI-D and DVI-I connectors. Also set the HPD (hotplug detection) flag for DVI-I connectors to prevent regressing their digital functionality, which has been already working. A subsequent commit will also implement polling for DVI-I. v2: Only use connector type for DVI to prevent regressions for other signal types.

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.

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.

disabled on DCN30 Before commit 33056a97ae5e ("drm/amd/display: Remove double checks for `debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL) checked the low-power debug flag before calling dpp3_power_on_blnd_lut(false). After commit 33056a97ae5e ("drm/amd/display: Remove double checks for `debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL) unconditionally calls dpp3_power_on_blnd_lut(false). The BLNDGAM power helper writes BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled, causing immediate SRAM power toggles instead of deferring at vupdate. This can disrupt atomic color/LUT sequencing during transitions between direct scanout and composition within gamescope's DRM backend on Steam Deck OLED. To fix this, leave the BLNDGAM power state unchanged when low-power is disabled, matching dpp3_power_on_hdr3dlut and dpp3_power_on_shaper.

2025-10-28drm/amd: Check that VPE has reached DPM0 in idle handlerMario Limonciello
[Why] Newer VPE microcode has functionality that will decrease DPM level only when a workload has run for 2 or more seconds. If VPE is turned off before this DPM decrease and the PMFW doesn't reset it when power gating VPE, the SOC can get stuck with a higher DPM level. This can happen from amdgpu's ring buffer test because it's a short quick workload for VPE and VPE is turned off after 1s. [How] In idle handler besides checking fences are drained check PMFW version to determine if it will reset DPM when power gating VPE. If PMFW will not do this, then check VPE DPM level. If it is not DPM0 reschedule delayed work again until it is. v2: squash in return fix (Alex) Cc: Peyton.Lee@amd.com Reported-by: Sultan Alsawaf <sultan@kerneltoast.com> Reviewed-by: Sultan Alsawaf <sultan@kerneltoast.com> Tested-by: Sultan Alsawaf <sultan@kerneltoast.com> Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4615 Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
