LIKWID-ACCESSD(1) General Commands Manual LIKWID-ACCESSD(1)

NAME

likwid-accessD - This tool forwards the access operations from LIKWID PerfMon tools to the MSR and PCI device files

DESCRIPTION

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 likwid-accessD requires the suid-bit set or a suitable libcap setting. Depending on the current system architecture, likwid-accessD permits only access to registers defined for the architecture.
