 |
|
Hi,
I have problems with my reatime clock (RTC). It looks like linux doesn't recognize my clock. He always start with the time gentoo last shutdowned. Ofcourse ntp works and so I got the right time.
The clock works in osX.
At the moment I am running 2.6.10-gentoo-r1.
my kernel.config ->
| Code: | # grep RTC linux/.config
CONFIG_GEN_RTC=y
# CONFIG_GEN_RTC_X is not set
# CONFIG_SENSORS_RTC8564 is not set
|
An error that I get when I try to start qemu:
| Quote: | Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux kernel or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.

That directory doesn't exist on ppc, it's only for the hardware clock found on x86 machines (HPET). Looks like that's not supported on PPC.
