2024-11-08drm/amdgpu: Fix map/unmap queue logicLijo Lazar
In current logic, it calls ring_alloc followed by a ring_test. ring_test in turn will call another ring_alloc. This is illegal usage as a ring_alloc is expected to be closed properly with a ring_commit. Change to commit the map/unmap queue packet first followed by a ring_test. Add a comment about the usage of ring_test. Also, reorder the current pre-condition checks of job hang or kiq ring scheduler not ready. Without them being met, it is not useful to attempt ring or memory allocations. Fixes tag refers to the original patch which introduced this issue which then got carried over into newer code.

2024-11-08drm/amdgpu: Add sysfs interface for gc reset maskJesse.zhang@amd.com
Add two sysfs interfaces for gfx and compute: gfx_reset_mask compute_reset_mask These interfaces are read-only and show the resets supported by the IP. For example, full adapter reset (mode1/mode2/BACO/etc), soft reset, queue reset, and pipe reset. V2: the sysfs node returns a text string instead of some flags (Christian) v3: add a generic helper which takes the ring as parameter and print the strings in the order they are applied (Christian) check amdgpu_gpu_recovery before creating sysfs file itself, and initialize supported_reset_types in IP version files (Lijo) v4: Fixing uninitialized variables (Tim) Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Suggested-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Tim Huang <tim.huang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2024-11-07drm/sched: Improve teardown documentationPhilipp Stanner
If jobs are still enqueued in struct drm_gpu_scheduler.pending_list when drm_sched_fini() gets called, those jobs will be leaked since that function stops both job-submission and (automatic) job-cleanup. It is, thus, up to the driver to take care of preventing leaks. The related function drm_sched_wqueue_stop() also prevents automatic job cleanup. Those pitfals are not reflected in the documentation, currently. Explicitly inform about the leak problem in the docstring of drm_sched_fini(). Additionally, detail the purpose of drm_sched_wqueue_{start,stop} and hint at the consequences for automatic cleanup.

2024-11-05drm/amdgpu/gfx11: Add cleaner shader for GFX11.0.3Srinivasan Shanmugam
This commit adds the cleaner shader microcode for GFX11.0.3 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_11_0_3_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.

2024-11-05drm/bridge: Add ITE IT6263 LVDS to HDMI converterLiu Ying
Add basic HDMI video output support. Currently, only RGB888 output pixel format is supported. At the LVDS input side, the driver supports single LVDS link and dual LVDS links with "jeida-24" LVDS mapping.

2024-11-05dt-bindings: display: Document dual-link LVDS display common propertiesLiu Ying
Dual-link LVDS displays receive odd pixels and even pixels separately from dual LVDS links. One link receives odd pixels and the other receives even pixels. Some of those displays may also use only one LVDS link to receive all pixels, being odd and even agnostic. Document common properties for those displays by extending LVDS display common properties defined in lvds.yaml.

Correct the workload setting in order not to mix the setting with the end user. Update the workload mask accordingly. v2: changes as below: 1. the end user can not erase the workload from driver except default workload. 2. always shows the real highest priority workoad to the end user. 3. the real workload mask is combined with driver workload mask and end user workload mask. v3: apply this to the other ASICs as well. v4: simplify the code v5: refine the code based on the review comments.

2024-11-04drm/amdkfd: Use dynamic allocation for CU occupancy array in ↵Srinivasan Shanmugam
'kfd_get_cu_occupancy()' The `kfd_get_cu_occupancy` function previously declared a large `cu_occupancy` array as a local variable, which could lead to stack overflows due to excessive stack usage. This commit replaces the static array allocation with dynamic memory allocation using `kcalloc`, thereby reducing the stack size. This change avoids the risk of stack overflows in kernel space, in scenarios where `AMDGPU_MAX_QUEUES` is large. The allocated memory is freed using `kfree` before the function returns to prevent memory leaks. Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c: In function ‘kfd_get_cu_occupancy’: drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:322:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=] 322 | } | ^ Fixes: 6ae9e1aba97e ("drm/amdkfd: Update logic for CU occupancy calculations") Cc: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> Cc: Felix Kuehling <felix.kuehling@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> Suggested-by: Mukul Joshi <mukul.joshi@amd.com> Reviewed-by: Mukul Joshi <mukul.joshi@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
