Looks like there is no cpu_get_real_ticks() function implementation for
sparc. There is an old message on qemu-devel discussing this issue [0].
It looks like this function is fairly easy to implement by reading the
%tick register in machines compliant with SPARC v9 architecture (Ultra1
or better), however the implementation for v8 architecture (and we are
building binaries for v8 in Debian) does not look so simple. I'd appreciate
any opinions or hints on this matter.
Slavio timer can be programmed to free run (user profiler) and with suitable
permissions, user programs can map the timer count register to their address
space and read the timer count value. I don't know what Linux does in this
respect.
