Documentation/gpu: Add a VM_BIND async document
Add a motivation for and description of asynchronous VM_BIND operation
v2:
- Fix typos (Nirmoy Das)
- Improve the description of a memory fence (Oak Zeng)
- Add a reference to the document in the Xe RFC.
- Add pointers to sample uAPI suggestions
v3:
- Address review comments (Danilo Krummrich)
- Formatting fixes
v4:
- Address typos (Francois Dugast)
- Explain why in-fences are not allowed for VM_BIND operations for long-
running workloads (Matthew Brost)
v5:
- More typo- and style fixing
- Further clarify the implications of disallowing in-fences for VM_BIND
operations for long-running workloads (Matthew Brost)
v6:
- Point out that a gpu_vm is a virtual GPU Address space.
(Danilo Krummrich)
- For an explanation of dma-fences point to the dma-fence documentation.
(Paulo Zanoni)
- Clarify that VM_BIND errors are reported synchronously. (Paulo Zanoni)
- Use an rst doc reference when pointing to the async vm_bind document
from the xe merge plan.
- Add the VM_BIND documentation to the drm documentation table-of-content,
using an intermediate "Misc DRM driver uAPI- and feature implementation
guidelines"
v7:
- Update the error handling documentation to remove the VM error state.
v8:
- Clarify error handling and difference in operation support between
async VM_BIND and sync VM_BIND. (Paulo Zanoni)
- Update the sample uAPI with a self-contained example. (Paulo Zanoni)
