Hi everyone,
Has FW_CFG_PPC_CPUFREQ been removed from QEMU for some reason? I noticed that
the value always comes back as 0 in OpenBIOS, and it looks as if the
FW_CFG_PPC_CPUFREQ constant (FW_CFG_ARCH_LOCAL + 0x4) has been removed from
hw/ppc.h?
In fact, it simply never got introduced :)
Yes - I see now from the archives that there was disagreement as to how
to obtain the CPU frequency to pass to OpenBIOS, and while the
FW_CFG_PPC_CPUFREQ value was removed from the final QEMU commit, it
still remains in the related OpenBIOS commit.
Well at least it explains why when booting an PPC OS in QEMU/OpenBIOS
all the CPU speeds appear as 0MHz ;)
ATB,
Mark.
