[PATCH v1 0/4] GPU Direct RDMA (P2P DMA) for Device Private Pages
...device private page data to devices such as
NICs, eliminating the need to traverse system RAM, which is the native
method for exposing device private page data.
To fully support Peer-to-Peer for device private pages, the following
changes are proposed:
`Memory Management (MM)`
* Leverage struct pagemap_ops to support P2P page operations: This
modification ensures that the GPU can directly map device private pages
for P2P DMA.
* Utilize hmm_range_fault to support P2P connections for device private
pages (instead of Page fault)
`IB Drivers`
Add TRY_P2P_REQ flag for the hmm_range_fault call: This flag...
