Few users left Who: Jeff Garzik <jeff@garzik.org> --------------------------- + +What: ACPI hooks (X86_SPEEDSTEP_CENTRINO_ACPI) in speedstep-centrino driver +When: December 2006 +Why: Speedstep-centrino driver with ACPI hooks and acpi-cpufreq driver are + functionally very much similar. They talk to ACPI in same way. Only + difference between them is the way they do frequency transitions. + One uses MSRs and the other one uses IO ports. Functionaliy of + speedstep_centrino with ACPI hooks is now merged into acpi-cpufreq. + That means one common driver will support all Intel Enhanced Speedstep + capable CPUs. That means less confusion over name of + speedstep-centrino driver (with that driver supposed to be used on + non-centrino platforms). That means less duplication of code and + less maintenance effort and no possibility of these two drivers + going out of sync. + Current users of speedstep_centrino with ACPI hooks are requested to + switch over to acpi-cpufreq driver. speedstep-centrino will continue + to work using older non-ACPI static table based scheme even after this + date. + +Who: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> + +--------------------------- |
