[PATCH v5 31/40] drm/msm: Add VM_BIND submitqueue

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> This submitqueue type isn't tied to a hw ringbuffer, but instead executes on the CPU for performing async VM_BIND ops.

[PATCH v5 29/40] drm/msm: Extract out syncobj helpers

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> We'll be re-using these for the VM_BIND ioctl. Also, rename a few things in the uapi header to reflect that syncobj use is not specific to the submit ioctl.

[PATCH v5 14/40] drm/msm: Convert vm locking

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> Convert to using the gpuvm's r_obj for serializing access to the VM. This way we can use the drm_exec helper for dealing with deadlock detection and backoff. This will let us deal with upcoming locking order conflicts with the VM_BIND implmentation (ie. in some scenarious we need to acquire the obj lock first, for ex. to iterate all the VMs an obj is bound in, and in other scenarious we need to acquire the VM lock first).

I might be repeating myself, but I think what you do here is a no-go and reimplements core system call functionality by a way which we certainly shouldn't allow. T.J's testing shows that sendfile() seems to work at least in one direction. The other use case can certainly be optimized. So if you want to improve this work on that instead.
