2024-09-10drm: new helper: drm_gem_prime_handle_to_dmabuf()Al Viro
Once something had been put into descriptor table, the only thing you can do with it is returning descriptor to userland - you can't withdraw it on subsequent failure exit, etc. You certainly can't count upon it staying in the same slot of descriptor table - another thread could've played with close(2)/dup2(2)/whatnot. drm_gem_prime_handle_to_fd() creates a dmabuf, allocates a descriptor and attaches dmabuf's file to it (the last two steps are done in dma_buf_fd()). That's nice when all you are going to do is passing a descriptor to userland. If you just need to work with the resulting object or have something else to be done that might fail, drm_gem_prime_handle_to_fd() is racy. The problem is analogous to one with anon_inode_getfd(), and solution is similar to what anon_inode_getfile() provides. Add drm_gem_prime_handle_to_dmabuf() - the "set dmabuf up" parts of drm_gem_prime_handle_to_fd() without the descriptor-related ones. Instead of inserting into descriptor table and returning the file descriptor it just returns the struct file. drm_gem_prime_handle_to_fd() becomes a wrapper for it. Other users will be introduced in the next commit.

2024-09-06drm/sched: add optional errno to drm_sched_start()Christian König
The current implementation of drm_sched_start uses a hardcoded -ECANCELED to dispose of a job when the parent/hw fence is NULL. This results in drm_sched_job_done being called with -ECANCELED for each job with a NULL parent in the pending list, making it difficult to distinguish between recovery methods, whether a queue reset or a full GPU reset was used. To improve this, we first try a soft recovery for timeout jobs and use the error code -ENODATA. If soft recovery fails, we proceed with a queue reset, where the error code remains -ENODATA for the job. Finally, for a full GPU reset, we use error codes -ECANCELED or -ETIME. This patch adds an error code parameter to drm_sched_start, allowing us to differentiate between queue reset and GPU reset failures. This enables user mode and test applications to validate the expected correctness of the requested operation. After a successful queue reset, the only way to continue normal operation is to call drm_sched_job_done with the specific error code -ENODATA. v1: Initial implementation by Jesse utilized amdgpu_device_lock_reset_domain and amdgpu_device_unlock_reset_domain to allow user mode to track the queue reset status and distinguish between queue reset and GPU reset. v2: Christian suggested using the error codes -ENODATA for queue reset and -ECANCELED or -ETIME for GPU reset, returned to amdgpu_cs_wait_ioctl. v3: To meet the requirements, we introduce a new function drm_sched_start_ex with an additional parameter to set dma_fence_set_error, allowing us to handle the specific error codes appropriately and dispose of bad jobs with the selected error code depending on whether it was a queue reset or GPU reset. v4: Alex suggested using a new name, drm_sched_start_with_recovery_error, which more accurately describes the function's purpose. Additionally, it was recommended to add documentation details about the new method. v5: Fixed declaration of new function drm_sched_start_with_recovery_error.(Alex) v6 (chk): rebase on upstream changes, cleanup the commit message, drop the new function again and update all callers, apply the errno also to scheduler fences with hw fences v7 (chk): rebased Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Signed-off-by: Vitaly Prosyak <vitaly.prosyak@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240826122541.85663-1-christian.koenig@amd.com

We want to determine the size of the devcoredump before writing it out. To that end, we will run the devcoredump printer with NULL data to get the size, alloc data based on the generated offset, then run the devcorecump again with a valid data pointer to print.

2024-07-26drm/vblank: add dynamic per-crtc vblank configuration supportHamza Mahfooz
We would like to be able to enable vblank_disable_immediate unconditionally, however there are a handful of cases where a small off delay is necessary (e.g. with PSR enabled). So, we would like to be able to adjust the vblank off delay and disable imminent values dynamically for a given CRTC. Since, it will allow drivers to apply static screen optimizations more quickly and consequently allow users to benefit more so from the power savings afforded by the aforementioned optimizations, while avoiding issues in cases where an off delay is still warranted. In particular, the PSR case requires a small off delay of 2 frames, otherwise display firmware isn't able to keep up with all of the requests made to amdgpu. So, introduce drm_crtc_vblank_on_config() which is like drm_crtc_vblank_on(), but it allows drivers to specify the vblank CRTC configuration before enabling vblanking support for a given CRTC.
