* drm/vmwgfx: Don't refcount cotable lookups during command buffer validationThomas Hellstrom2018-09-281-3/+2
| | | | | | | | | | | | | | | The typical pattern of these lookups are -Lookup -Put on validate list if not already there. -Unreference And since we are the exclusive user of the context during lookup time, we can be sure that the resource will stay alive during the sequence. So avoid taking a reference during lookup, and also avoid unreferencing when done. There are two users outside of command buffer validation and those are refcounted explicitly.

* drm/vmwgfx: Make the object handles idr-generatedThomas Hellstrom2018-09-271-8/+4
| | | | | | | | | | | | | | | Instead of generating user-space object handles based on a, possibly processed, hash of the kernel address of the object, use idr to generate and lookup those handles. This might improve somewhat on security since we loose all connections to the object's kernel address. Also idr is designed to do just this. As a todo-item, since user-space handles are now generated in sequence, we can probably use a much simpler hash function to hash them.

* drm/vmwgfx: Remove the resource avail fieldThomas Hellstrom2018-09-271-4/+2
| | | | | | | | | | | | | | | | | This field was previously used to prevent a lookup of a resource before its constructor had run to its end. This was mainly intended for an interface that is now removed that allowed looking up a resource by its device id. Currently all affected resources are added to the lookup mechanism (its TTM prime object is initialized) late in the constructor where it's OK to look up the resource. This means we can change the device resource_lock to an ordinary spinlock instead of an rwlock and remove a locking sequence during lookup.

| * drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom2018-07-031-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

| | | | | | | | | | | | | | | | | | When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings. Makes suspend and hibernate now also work with legacy user-space drivers on guest-backed devices. v2: Don't rebind on legacy devices.
