linux-user/strace.list: add riscv_hwprobe entry

[PATCH] linux-user/strace.list: add riscv_hwprobe entry

Posted by Daniel Henrique Barboza 3 months, 2 weeks ago

We're missing a strace entry for riscv_hwprobe, and using -strace will
report it as "Unknown syscall 258".

After this patch we'll have:

$ ./build/qemu-riscv64 -strace test_mutex_riscv
110182 riscv_hwprobe(0x7f207efdc700,1,0,0,0,0) = 0
110182 brk(NULL) = 0x0000000000082000
(...)
