Hi Manav,

I guess disabling the caches is hardware independant. for my case it's
realized by modifying the MSR, at least i guess so:)

excuse my  naive question .. but is it allowed to turn off L1,L2 caching at run-time by modifying the MSR ?.. maybe the machine needs to be restarted to start working without it's CPU caches .. CMIIW
thanks

late this afternoon i found out that i forgot to enable msr support in
my kernel configuration (that could be the point...), that's stupid,
any way, i will try tomorrow.

if there is any possibility to disable it in Linux, please also let me
know. Thanks in advanced!

with kind regards,

Yang
