The patch series covers the points discussed in November 2021 virtual call
[LSF/MM/BFP TOPIC] Storage: Copy Offload[0].
We have covered the Initial agreed requirements in this patchset.
Patchset borrows Mikulas's token based approach for 2 bdev
implementation.
Overall series supports –
1. Driver
- NVMe Copy command (single NS), including support in nvme-target (for
block and file backend)
It would also be nice to have copy offload emulation in null_blk for testing.
We can plan this in next phase of copy support, once this series settles down.
So how can people test your series ? Not a lot of drives out there with
copy support.
Yeah not many drives at present, Qemu can be used to test NVMe copy.
Upstream QEMU ? What is the command line options ? An example would be
nice. But I still think null_blk support would be easiest.
+1 for adding copy offloading support in null_blk. That enables running
copy offloading tests without depending on Qemu.
Thanks,
Bart.
