Years In The Making, Intel Timed I/O "TIO" Looks To Finally Land In Linux 6.15
Intel Timed I/O 'TIO' has been present on Intel processors going back to 2019 and the Linux driver support has been worked on for several years, but finally this year with the upcoming Linux 6.15 cycle is this Intel Timed I/O code expected to be merged.
