Hello Felix Singer, Lance Zhao, build bot (Jenkins), Matt Delco, Nico Huber, Furquan Shaikh, Paul Menzel, Tim Wawrzynczak, Ravindra, Subrata Banik, Lean Sheng Tan, Patrick Rudolph,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/47543
to look at the new patch set (#27).
Change subject: soc/intel/{icl,tgl,jsl,ehl}: enable ACPI CPPC entries ......................................................................
soc/intel/{icl,tgl,jsl,ehl}: enable ACPI CPPC entries
Enable CPPC entries generation, needed for Intel SpeedShift.
This can be tested by checking sysfs in Linux: $ grep . /sys/devices/system/cpu/cpu?/acpi_cppc/*perf
The output should look like this, while the values may differ:
/sys/devices/system/cpu/cpu0/acpi_cppc/highest_perf:28 /sys/devices/system/cpu/cpu0/acpi_cppc/lowest_nonlinear_perf:5 /sys/devices/system/cpu/cpu0/acpi_cppc/lowest_perf:1 /sys/devices/system/cpu/cpu0/acpi_cppc/nominal_perf:24 /sys/devices/system/cpu/cpu1/acpi_cppc/highest_perf:28 /sys/devices/system/cpu/cpu1/acpi_cppc/lowest_nonlinear_perf:5 ...
