The register access is done by opening the file and seeking to the MSR number as offset in the file and then read or write in chunks of 8 bytes. A larger size than 8 bytes means multiple reads or writes of the same register. .SH NOTES The .I msr driver is not auto-loaded. On modular kernel you might need to use .B modprobe msr to load it explicitely before use. .SH SEE ALSO Intel Corporation Intel 64 and IA-32 Architectures Software Developer's Manual Volume 3B Appendix B for an overview of the Intel CPU MSRs. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
