Strange frequency reported by the kernel
Dear people,
I received a G3 upgrade card for a PowerMac 9500 as a gift from one of the
subscribers of this list (hi, Tormod!).
I replaced the dual 180/MP G04e daughter card with this new G3 upgrade and
the last time that I booted with MacOS 8.1, it reported the card being
having a G3 450MHz.
I have eliminated MacOS from my system and went Debian only, but one
curious thing I saw with kernels from the 2.2, 2.4 and 2.6 series is that
they report the frequency of the processor as 195MHz. The bogomips count
presented in /proc/cpuinfo indicates 796.67, which would lead me to believe
that there is something slightly wierd with this setup.
Here is the complete /proc/cpuinfo on this machine:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
processor : 0
cpu : 740/750
clock : 195MHz
revision : 131.0 (pvr 0008 8300)
bogomips : 796.67
machine : Power Macintosh
motherboard : AAPL,9500 MacRISC
detected as : 16 (PowerMac 9500/9600)
pmac flags : 00000000
L2 cache : 512K unified
memory : 64MB
pmac-generation : OldWorld
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
I also learned that I should enable the L2 cache of this card to get better
performance. Is this indeed necessary?
I am open to any questions regarding my setup.
Thanks in advance for any help, Rogério Brito.
