[PATCH v3 2/2] Add a selftest for the sparc64 privileged ADI driver. These tests verify the read(), pread(), write(), pwrite(), and seek() functionality of the driver. The tests also report simple performance statistics:
From: Tom Hromatka
Date: Fri Apr 20 2018 - 15:39:55 EST
Syscall Call AvgTime AvgSize
Count (ticks) (bytes)
-------------------------------
read 3 119638 8133
pread 4 118164 6741
write 3 339442 8133
pwrite 4 280134 6741
seek 10 2919 0
Pass 8 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
