2020-11-09drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backendsThomas Zimmermann
This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian) * fix a trailing { in drm_gem_vmap() * remove several empty functions instead of converting them (Daniel) * comment uses of raw pointers with a TODO (Daniel) * TODO list: convert more helpers to use struct dma_buf_map Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Christian König <christian.koenig@amd.com> Tested-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-7-tzimmermann@suse.de

2013-07-25drm/ttm: convert to unified vma offset managerDavid Herrmann
Use the new vma-manager infrastructure. This doesn't change any implementation details as the vma-offset-manager is nearly copied 1-to-1 from TTM. The vm_lock is moved into the offset manager so we can drop it from TTM. During lookup, we use the vma locking helpers to take a reference to the found object. In all other scenarios, locking stays the same as before. We always guarantee that drm_vma_offset_remove() is called only during destruction. Hence, helpers like drm_vma_node_offset_addr() are always safe as long as the node has a valid offset. This also drops the addr_space_offset member as it is a copy of vm_start in vma_node objects. Use the accessor functions instead. v4: - remove vm_lock - use drm_vma_offset_lock_lookup() to protect lookup (instead of vm_lock) Cc: Dave Airlie <airlied@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Martin Peres <martin.peres@labri.fr> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@gmail.com>
2013-07-24qxl: convert qxl driver to proper use for reservationsDave Airlie
The recent addition of lockdep support to reservations and their subsequent use by TTM showed up a number of potential problems with the way qxl was using TTM objects. a) it was allocating objects, and reserving them later without validating underneath the reservation, which meant in extreme conditions the objects could be evicted before the reservation ever used them. b) it was reserving objects straight after allocating them, but with no ability to back off should the reservations fail. It now allocates the necessary objects then does a complete reservation pass on them to avoid deadlocks. c) it had two lists per release tracking objects, unnecessary complicating the reservation process. This patch removes the dual object tracking, adds reservations ticket support to the release and fence object handling. It then ports the internal fb drawing code and the userspace facing ioctl to use the new interfaces properly, along with cleanup up the error path handling in some codepaths.

2013-07-24qxl: allow creation of pre-pinned objects and use for releases.Dave Airlie
In order to fix an issue with reservations we need to create the releases as pre-pinned objects, this changes the placement interface and bo creation interface to allow creating pinned objects to save nested reservations later. This is just a stepping stone to main fix which follows to actually fix how qxl deals with reservations. Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-06-28drm/ttm: convert to the reservation apiMaarten Lankhorst
Now that the code is compatible in semantics, flip the switch. Use ww_mutex instead of the homegrown implementation. ww_mutex uses -EDEADLK to signal that the caller has to back off, and -EALREADY to indicate this buffer is already held by the caller. ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes were needed to handle this correctly.

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie
QXL is a paravirtual graphics device used by the Spice virtual desktop interface. The drivers uses GEM and TTM to manage memory, the qxl hw fencing however is quite different than normal TTM expects, we have to keep track of a number of non-linear fence ids per bo that we need to have released by the hardware. The releases are freed from a workqueue that wakes up and processes the release ring. releases are suballocated from a BO, there are 3 release categories, drawables, surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling. The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface ids. This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice. Authors: Dave Airlie, Alon Levy v1.1: fixup some issues in the ioctl interface with padding v1.2: add module device table v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq, don't try flush release ring (broken hw), fix -modesetting. v1.4: fbcon cpu usage reduction + suitable accel flags.
