ACPI_SMC_PlatformPlugin.kext needed #2

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Install Jas 10.5.4 
2.Install Speedstep kext and app 
3.kext is unable to get the pstates from ACPI 

What is the expected output? What do you see instead?
kext is unable to get the pstates from ACPI

What version of the kext are you using? On what kernel and processor?
1.3.2

Please provide any additional information below.
This is actually not a bug in the kext but I thought it might be important
to mark; Some releases (like JaS one) have the IOPlatformPluginFamiliy.kext
disable by default. Without the ACPI_SMC_PlatformPlugin.kext (inside
IOPlatformPluginFamiliy.kext) the Intelenhancedspeedstep.kext isnt able to
get the pstates

Please turn on DebugMessages in the Info.plist, reload the kext and try to
reproduce the problem. Attach output of this command:
sudo dmesg | grep IntelEnhanced && sysctl hw.busfrequency && sysctl
machdep.cpu && uname -a

In case you get kernel panic, boot up in single user mode (bootflag -s),
load the kext manually, and note down or take a photo of the kernel panic
message. Attach it as well.

Good find, thanks. I'll see if I can do something about it, e.g. add a 
dependency on that kext.
