With the help of others replying to a different post of mine, I got my =
cache enabled with l2cr=3D0xb9080000 kernel arg, . Thanks!
However, my /proc/cpuinfo isn't the same as when I set the cache using =
BootX
(/proc/sys/kernel/l2cr is the same with both methods of setting the =
cache, as
expected). When setting the G3 cache using BootX, /proc/cpuinfo shows
cpu : 740/750
temperature : 21-24 C (uncalibrated)
clock : 195MHz
revision : 130.1 (pvr 0008 8201)
bogomips : 673.38
machine : Power Macintosh
motherboard : AAPL,7500 MacRISC
detected as : 16 (PowerMac 7500)
pmac flags : 00000000
L2 cache : 256K unified <-----I still have orig. cache card installed
memory : 176MB
l2cr override : 0xb9080000 <------Here's the extra entry
pmac-generation : OldWorld
Here's /proc/cpuinfo when cache is disabled or enabled by method other =
than BootX
cpu : 740/750
temperature : 21-23 C (uncalibrated)
clock : 195MHz
revision : 130.1 (pvr 0008 8201)
bogomips : 673.38
machine : Power Macintosh
motherboard : AAPL,7500 MacRISC
detected as : 16 (PowerMac 7500)
pmac flags : 00000000
L2 cache : 256K unified
memory : 176MB
pmac-generation : OldWorld
Here's /proc/sys/kernel/l2cr when cache is enabled just in case it might =
be
important.
0xb9080000: enabled, no parity, 1MB, +2 clock, pipelined burst SRAM,
write-through, 0.5ns hold
So, my question. Is the entry in /proc/cpuinfo for 'l2cr override' =
important?
Does it indicate something else has been set other than just the cache? =
Is
there another kernel arg to enable this 'override' option?
Can anyone elaborate on this?
TIA,
Mike Kimmick
