# HEAD: a7e1f67ed29f0c339e2aa7483d13b085127566ab x86/msr: Filter MSR writes
Filter MSR writes from user-space by default, and print a syslog entry if they happen outside the allowed set of MSRs, which is a single one for now, MSR_IA32_ENERGY_PERF_BIAS.
The plan is to eventually disable MSR writes by default (they can still be enabled via allow_writes=on).
Signed-off-by: Ingo Molnar <mingo@kernel.org> Thanks,
Ingo
