* drm/amdgpu: disable BAR resize on Dell G5 SEAlex Deucher2025-02-251-0/+7
| | | | | | | | | | | | | | | | | | There was a quirk added to add a workaround for a Sapphire RX 5600 XT Pulse that didn't allow BAR resizing. However, the quirk caused a regression with runtime pm on Dell laptops using those chips, rather than narrowing the scope of the resizing quirk, add a quirk to prevent amdgpu from resizing the BAR on those Dell platforms unless runtime pm is disabled. v2: update commit message, add runpm check Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/1707 Fixes: 907830b0fc9e ("PCI: Add a REBAR size quirk for Sapphire RX 5600 XT Pulse") Reviewed-by: Lijo Lazar <[email protected]> Signed-off-by: Alex Deucher <[email protected]> (cherry picked from commit 5235053f443cef4210606e5fb71f99b915a9723d) Cc: [email protected]

| | | | | | | | | | | | | | | | | | | This commit enables the cleaner shader feature for GFX12.0 and GFX12.0.1 GPUs. The cleaner shader is important for clearing GPU resources such as Local Data Share (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs) between workloads. - This feature ensures that GPU resources are reset between workloads, preventing data leaks and ensuring accurate computation. By enabling the cleaner shader, this update enhances the security and reliability of GPU operations on GFX12.0 hardware.

The problem was identified by a warning indicating a potential deadlock due to inconsistent lock acquisition order. - The `amdgpu_gfx_enforce_isolation_ring_begin_use` and `amdgpu_gfx_enforce_isolation_ring_end_use` functions previously acquired `enforce_isolation_mutex` and called `amdgpu_gfx_kfd_sch_ctrl`, leading to potential deadlocks. ie., If `amdgpu_gfx_kfd_sch_ctrl` is called while `enforce_isolation_mutex` is held, and `amdgpu_gfx_enforce_isolation_handler` is called while `kfd_sch_mutex` is held, it can create a circular dependency. By ensuring consistent lock usage, this fix resolves the issue: [ 606.297333] ====================================================== [ 606.297343] WARNING: possible circular locking dependency detected [ 606.297353] 6.10.0-amd-mlkd-610-311224-lof #19 Tainted: G OE [ 606.297365] ------------------------------------------------------ [ 606.297375] kworker/u96:3/3825 is trying to acquire lock: [ 606.297385] ffff9aa64e431cb8 ((work_completion)(&(&adev->gfx.enforce_isolation[i].work)->work)){+.+.}-{0:0}, at: __flush_work+0x232/0x610 [ 606.297413] but task is already holding lock: [ 606.297423] ffff9aa64e432338 (&adev->gfx.kfd_sch_mutex){+.+.}-{3:3}, at: amdgpu_gfx_kfd_sch_ctrl+0x51/0x4d0 [amdgpu] [ 606.297725] which lock already depends on the new lock.

It's unlikely that people will be using this driver on 32bit kernels and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16) bits. So this bug does not affect anything in real life.

| * drm/amdgpu/gfx10: Add cleaner shader for GFX10.3.0Srinivasan Shanmugam2025-01-063-0/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds the cleaner shader microcode for GFX10.3.0 GPUs. The cleaner shader is a piece of GPU code that is used to clear or initialize certain GPU resources, such as Local Data Share (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs). Clearing these resources is important for ensuring data isolation between different workloads running on the GPU. Without the cleaner shader, residual data from a previous workload could potentially be accessed by a subsequent workload, leading to data leaks and incorrect computation results. The cleaner shader microcode is represented as an array of 32-bit words (`gfx_10_3_0_cleaner_shader_hex`). This array is the binary representation of the cleaner shader code, which is written in a low-level GPU instruction set. When the cleaner shader feature is enabled, the AMDGPU driver loads this array into a specific location in the GPU memory. The GPU then reads this memory location to fetch and execute the cleaner shader instructions. The cleaner shader is executed automatically by the GPU at the end of each workload, before the next workload starts. This ensures that all GPU resources are in a clean state before the start of each workload. This addition is part of the cleaner shader feature implementation. The cleaner shader feature helps resource utilization by cleaning up GPU resources after they are used. It also enhances security and reliability by preventing data leaks between workloads.

| * | drm/amdgpu: track bo memory stats at runtimeYunxiang Li2024-12-199-139/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, every time fdinfo is queried we try to lock all the BOs in the VM and calculate memory usage from scratch. This works okay if the fdinfo is rarely read and the VMs don't have a ton of BOs. If either of these conditions is not true, we get a massive performance hit. In this new revision, we track the BOs as they change states. This way when the fdinfo is queried we only need to take the status lock and copy out the usage stats with minimal impact to the runtime performance. With this new approach however, we would no longer be able to track active buffers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers. Make drm-active- optional to enable amdgpu to switch to the second method.
