Hi，
I have read some papers about Linux/acpi. I want to ask a question.
1 .The acpica is a part of OSPM. Cpufreq and cpuidle uses some interface in ACPI processor drivers.
2. In ACPI specifications 4.0 ，something like OSPM system code. Although it is a abstract description,
OSPM system code means something kernel modules like cpufreq and cpuidle？But they are in kernel, why
does it make a difference between kernel and OSPM system code?
3. Acpica is independent of Linux/acpi， they are glued with the OSL layer. So the Linux/acpi is mainly
about device drivers?
Thank you for your appreciation!
