Recently a new low-level RDMA driver went upstream, namely the SoftiWARP
driver. That driver implements RDMA over TCP. Support has been added in the
SRP initiator and target drivers for iWARP. This patch series adds a test
for SRP over SoftiWARP. Please consider integration of this patch series in
the official blktests repository.
Changes compared to v1:
- Only run the new test if the kernel version is at least 5.5 (the version in
which iWARP support was added to the SRP drivers) and if "rdma link" is
supported.
Is there no way to detect this feature other than checking the kernel
version?
Hi Omar,
The only other way I can think of to verify whether the SRP initiator
and target drivers support iWARP is by loading the SRP drivers, loading
the iWARP driver, by configuring LIO + ib_srpt and by attempting to set
up a connection. However, I assume that's way more than what a _have()
test should do?
Bart.
