13 sve-stress performs an SVE context switch stress test, as described
17 "sve" in the following commands.)
25 $ ./sve-stress
67 To try to reproduce the bugs that we have been observing, sve-stress
73 $ lkvm run --console=virtio -pconsole=hvc0 --sve Image
89 guest$ ./vlset --inherit 32 ./sve-stress
91 3) Run the sve-stress on the host with the maximum Vector-Length:
92 host$ ./vlset --inherit --max ./sve-stress
