.TH LIKWID-ACCESSD 1 26.11.2018 likwid\-4 .SH NAME likwid-accessD \- This tool forwards the access operations from LIKWID PerfMon tools to the MSR and PCI device files .SH DESCRIPTION .B likwid-accessD is a command line application that opens a UNIX file socket and waits for access operations from LIKWID tools that require access to the MSR and PCI device files. The MSR and PCI device files are only accessible for users with root privileges, therefore .B likwid-accessD requires the suid-bit set or a suitable libcap setting. Depending on the current system architecture, .B likwid-accessD permits only access to registers defined for the architecture. .SH AUTHOR Written by Thomas Roehl . .SH BUGS Report Bugs on . .SH "SEE ALSO" likwid-perfctr(1), likwid-powermeter(1), likwid-features(1)
