I tried to apply the diff to latest RELENG_6. Then, it seems voltage
is not handled correctly on my laptop. My CPU is 753.
[EMAIL PROTECTED]:1010% sysctl dev.est
dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.0.freq_settings: 1200/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1
The following is the sysctl output before applying the diff.
[EMAIL PROTECTED]:1004% sysctl dev.est
dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.0.%driver: est
dev.est.0.%parent: cpu0
dev.est.0.freq_settings: 1200/5000 1100/4700 1000/4300 900/4000 800/3700
600/3000
What happens is that acpi_perf attaches as "info only" if it doesn't
have a method to control the frequency. For example, the control/status
methods might list a hardware-specific control mechanism. Something
about how the new est is attaching is causing acpi_perf to not attach in
info-only mode.
