Message-ID: <45B625F1.6000500@comcast.net> (raw)
Has anyone looked into cpufreq support for the AMD LX800? It provides
control over the CPU PLL via MSR 4C000014h, but it has this ominous
statement in the datasheet:
When using this register to change the PLL frequencies, the
CHIP_RESET bit should be set.
From viewing the other AMD cpufreq drivers, it appears they do not
require a chip reset. This sounds like a bad thing, since I don't have
a clue how to save the cpu state, reset, and restore the cpu state. Is
this a big deal?
Thanks,
Paul
