drm/nouveau/mmu: swap out round for ALIGN · 6497c2ba

由 Ben Skeggs 提交于 11月 03, 2017

Rounding value is guaranteed to be power-of-two, so this is better
anyway.

Fixes build on 32-bit.

  drm/nouveau: queue delayed unmapping of VMAs on client workqueue · 00d041d0
  由 Ben Skeggs 提交于 11月 01, 2017
```
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.

  drm/nouveau: check kind validity against mmu object · a220dd73
  由 Ben Skeggs 提交于 11月 01, 2017
```
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.

  drm/nouveau/mmu: implement new vmm frontend · f9463a4b
  由 Ben Skeggs 提交于 11月 01, 2017
```
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.
