Add support for _PDC/_OSC by advertising that we support direct access to the PERF_CTL/STS MSRs via the new acpi_get_features() method. This should allow newer systems to use SpeedStep. 2005-04-04 15:51:13 +00:00			`.if ${MACHINE} == "i386" \|\| ${MACHINE} == "amd64"`

cpufreq(4): Add support for Intel Speed Shift Intel Speed Shift is Intel's technology to control frequency in hardware, with hints from software. Let's get a working version of this in the tree and we can refine it from here. Submitted by: bwidawsk, scottph Reviewed by: bcr (manpages), myself Discussed with: jhb, kib (earlier versions) With feedback from: Greg V, gallatin, freebsdnewbie AT freenet.de Relnotes: yes Differential Revision: https://reviews.freebsd.org/D18028 2020-01-22 23:28:42 +00:00			`SRCS+= est.c hwpstate_amd.c p4tcc.c powernow.c hwpstate_intel.c`

Add a driver for SMI-based SpeedStep. The hardware supports two frequency settings and is an older version of the same design used for ICH SpeedStep. It is only known to be available on PIIX4 chipsets. Many thanks to Bruno Ducrot for writing the driver and Jon Noack for testing.
