WebJun 21, 2024 · You need to explicitly control the processor that executes the WRMSR and RDMSR instructions. The kernel that I am using (3.10.0-693) uses the functions "wrmsrl_on_cpu ()" and "rdmsrl_on_cpu ()" (defined in arch/x86/lib/msr-smp.c) to read and write MSRs on a specific logical processor. WebMay 7, 2015 · rdmsr:pread: Input/output error I determined that the "rdmsr:pread: Input/output error" occurs when trying to read the MSR_PP1_ENERGY_STATUS (0x641). Can anybody tell me why precisely I am getting this error. Am I using a wrong value of the MSR. BTW, this code works just fine on my i5-4430 machine. 0 Kudos Share Reply 1 Solution how do i print my tickets from tuacahn
