.TH LIKWID-ACCESSD 1 10.11.2023 likwid\-5 .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/PCI device files or MMIO ranges. The MSR/PCI device files and MMIO rangesare 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 Gruber . .SH BUGS Report Bugs on . .SH "SEE ALSO" likwid-perfctr(1), likwid-powermeter(1), likwid-features(1)
