[Qemu-devel] [PATCH] sysctl

[Timo Savola]

Hello,

Since the user-mode qemu doesn't support sysctl (syscall 149) and
linuxthreads uses it to check kernel/version, some programs fail.  sysctl
is an obsolete syscall and seems like a big job to support since you'd
have to know what kind of data goes in and out with each parameter, so
I'm not surprised why it's not supported.  However, implementing only the
kernel/version case seems worthwhile.  I tested this patch with qemu-arm
and it seems to help.

Extending this patch to implement all cases that copy string (or integer)
values would be straightforward, but I wanted to keep the patch simple.
