atomic_get_input_bus_fmts is only implemented for LVDS decoders, resulting that LVDS encoders only support bus format MEDIA_BUS_FMT_FIXED. This results in warnings like: mxsfb 21c8000.lcdif: Bridge does not provide bus format, assuming MEDIA_BUS_FMT_RGB888_1X24. Please fix bridge driver by handling atomic_get_input_bus_fmts. Fix this by reusing lvds_codec_atomic_get_input_bus_fmts currently used for LVDS decoders. Use RGB888_1X24 for LVDS encoders. This also allows removing the dedicated struct drm_bridge_funcs for decoders. Signed-off-by:

The driver depends on CONFIG_OF, so it is not necessary to use of_match_ptr here. Even for drivers that do not depend on CONFIG_OF, it's almost always better to leave out the of_match_ptr(), since the only thing it can possibly do is to save a few bytes of .text if a driver can be used both with and without it. Hence we remove of_match_ptr. Signed-off-by:

Provide the driver indirection iterating over all DRM GPU VA spaces to enable the common 'gpuvas' debugfs file for dumping DRM GPU VA spaces. Reviewed-by:
-
Danilo Krummrich authored
This commit provides the implementation for the new uapi motivated by the Vulkan API. It allows user mode drivers (UMDs) to: 1) Initialize a GPU virtual address (VA) space via the new DRM_IOCTL_NOUVEAU_VM_INIT ioctl for UMDs to specify the portion of VA space managed by the kernel and userspace, respectively. 2) Allocate and free a VA space region as well as bind and unbind memory to the GPUs VA space via the new DRM_IOCTL_NOUVEAU_VM_BIND ioctl. UMDs can request the named operations to be processed either synchronously or asynchronously. It supports DRM syncobjs (incl. timelines) as synchronization mechanism. The management of the GPU VA mappings is implemented with the DRM GPU VA manager. 3) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl. The execution happens asynchronously. It supports DRM syncobj (incl. timelines) as synchronization mechanism. DRM GEM object locking is handled with drm_exec. Both, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC, use the DRM GPU scheduler for the asynchronous paths. Reviewed-by:

The new VM_BIND UAPI uses the DRM GPU VA manager to manage the VA space. Hence, we a need a way to manipulate the MMUs page tables without going through the internal range allocator implemented by nvkm/vmm. This patch adds a raw interface for nvkm/vmm to pass the resposibility for managing the address space and the corresponding map/unmap/sparse operations to the upper layers. Reviewed-by:

The new VM_BIND UAPI implementation introduced in subsequent commits will allow asynchronous jobs processing push buffers and emitting fences. If a job times out, we need a way to recover from this situation. For now, simply kill the channel to unblock all hung up jobs and signal userspace that the device is dead on the next EXEC or VM_BIND ioctl. Reviewed-by:

Danilo Krummrich authored
The new VM_BIND UAPI implementation introduced in subsequent commits will allow asynchronous jobs processing push buffers and emitting fences. If a fence context is killed, e.g. due to a channel fault, jobs which are already queued for execution might still emit new fences. In such a case a job would hang forever. To fix that, fail to emit a new fence on a killed fence context with -ENODEV to unblock the job. Reviewed-by:

Danilo Krummrich authored
The new (VM_BIND) UAPI exports DMA fences through DRM syncobjs. Hence, in order to emit fences within DMA fence signalling critical sections (e.g. as typically done in the DRM GPU schedulers run_job() callback) we need to separate fence allocation and fence emitting. Reviewed-by:
