Given that VPU generation can be used by multiple platforms, driver should use VPU IP generation names instead of a platform. Change naming for functions and registries. Use 37XX format, where: 3 - major VPU IP generation version 7 - minor VPU IP generation version XX - postfix indicating this is an architecture and not marketing name Signed-off-by:

The flags field in drm_syncobj_find_fence() takes SYNCOBJ_WAIT flags from the syncobj UAPI whereas sync->flags is from the nouveau UAPI. What we actually want is 0 flags which tells it to just try to find the fence and then return without waiting.

VMAs can find their corresponding VM through their embedded struct drm_gpuva which already carries a pointer to a struct drm_gpuva_manager which the VM is based on. Hence, remove the struct nouveau_uvmm pointer from struct nouveau_uvma to save a couple of bytes per mapping. Reviewed-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:

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:

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:

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:

nouveau > 10 years ago had a plan for new multiplexer inside a multiplexer API using nvif. It never fully reached fruition, fast forward 10 years, and the new vulkan driver is avoiding libdrm and calling ioctls, and these 3 ioctls, getparam, channel alloc + free don't seem to be things we'd want to use nvif for. Undeprecate and put them into the uapi header so we can just copy it into mesa later. v2: use uapi types. Reviewed-by:

When no custom lock is set to protect a GEMs GPUVA list, lockdep checks should fall back to the GEM objects dma-resv lock. With the current implementation we're setting the lock_dep_map of the GEM objects 'resv' pointer (in case no custom lock_dep_map is set yet) on drm_gem_private_object_init(). However, the GEM objects 'resv' pointer might still change after drm_gem_private_object_init() is called, e.g. through ttm_bo_init_reserved(). This can result in the wrong lock being tracked. To fix this, call dma_resv_held() directly from drm_gem_gpuva_assert_lock_held() and fall back to the GEMs lock_dep_map pointer only if an actual custom lock is set.

The commit c242f484 ("drm: Make FB_CORE to be selected if DRM fbdev emulation is enabled") changed DRM_FBDEV_EMULATION from 'depends on FB' to an effective 'select FB_CORE', so any config that previously had DRM=y and FB=n now has FB_CORE=y and FRAMEBUFFER_CONSOLE=y. This leads to unmet direct dependencies detected for FRAMEBUFFER_CONSOLE as reported by Arthur Grillo, e.g: WARNING: unmet direct dependencies detected for FRAMEBUFFER_CONSOLE Depends on [n]: VT [=n] && FB_CORE [=y] && !UML [=y] Selected by [y]: - DRM_FBDEV_EMULATION [=y] && HAS_IOMEM [=y] && DRM [=y] && !EXPERT [=n] Arnd Bergmann suggests to drop the select FRAMEBUFFER_CONSOLE for the DRM_FBDEV_EMULATION Kconfig symbol, since a possible use case could be to enable DRM fbdev emulation but without a framebuffer console.
