VMAs are about to not take references on the VMM they belong to, which means more care is required when handling delayed unmapping. Queuing it on the client workqueue ensures all pending VMA unmaps will have completed before the VMM is destroyed. Signed-off-by: -

This is already handled in the top-level gem_new() ioctl in another manner, but this will be removed in a future commit. Ideally we'd not need to check up-front at all, and let the VMM code handle error checking, but there are paths in the current BO management code where this isn't possible due to map() not always being called during BO creation, and map() calls not being allowed to fail during buffer migration.

If the VMA is being deleted, we don't need to explicity unmap first anymore. The MMU code will automatically merge the operations into a single page tree walk. Signed-off-by: -

These are the new priviledged interfaces to the VMM backends, and expose some functionality that wasn't previously available. It's now possible to allocate a chunk of address-space (even all of it), without causing page tables to be allocated up-front, and then map into it at arbitrary locations. This is the basic primitive used to support features such as sparse mapping, or to allow userspace control over its own address-space, or HMM (where the GPU driver isn't in control of the address-space layout). Rather than being tied to a subtle combination of memory object and VMA properties, arguments that control map flags (ro, kind, etc) are passed explicitly at map time. The compatibility hacks to implement the old frontend on top of the new driver backends have been replaced with something similar to implement the old frontend's interfaces on top of the new frontend.
