Fantastic! On OrangePi RV2 "lsusb" shows the USB3 host:
# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. Hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 002: ID 05e3:0620 Genesys Logic, Inc. GL3523 Hub
I haven't been able to access devices yet, but I guess I'm missing some
kernel modules....
And on PCIe, I could read the contents of a Raspberry Pi SSD disk:# dd
if=/dev/nvme0n1 of=/dev/null status=progress bs=4M
255730909184 bytes (256 GB, 238 GiB) copied, 664 s, 385 MB/s
61049+1 records in
61049+1 records out
256060514304 bytes (256 GB, 238 GiB) copied, 672.782 s, 381 MB/s
The SSD was freaking hot though :}
Tested-by: Michael Opdenacker <michael.opdenacker@rootcommit.com>
I'm excited to have these features in the mainline kernel, hopefully soon.
Thanks again,
Michael.
