| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In VM debug mode, it is desirable to notify the application to correct the freeing sequence by unmapping the memory before destroying the userptr in the old userptr path.

This patches covers the following scenarios: - If VF is already in RMA state, then do not attempt to contact the host. Host will ignore the VF after sending the notification. - If the notification is detected during polling, then set the RMA status, and return error to caller. - If the notification arrives by interrupt, then set the RMA status and queue a reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | APUs in passthrough mode use HDP flush. 0x7F000 offset used for remapping HDP flush is mapped to VPE space which could get power gated. Use another unused offset in BIF space. Signed-off-by: Lijo Lazar <[email protected]> Acked-by: Alex Deucher <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If peer memory is XGMI-accessible, we should never access it through PCIe P2P DMA mappings. PCIe P2P is slower, has different coherence behaviour, limited or no support for atomics, or may not work at all. Fail with a warning if DMABUF mappings of such memory are attempted.
