cpufreq: CPPC: Initialize and check CPUFreq CPU co-ord type correctly

2015-11-23T21:21:18Z

The CPU policy struct indicates the co-ordination type for all CPUs of a common freq domain. Initialize it correctly using the CPU specific data gathered from CPPC ACPI lib via acpi_get_psd_map(). The PSD object is optional, so the cpu->shared_type can also be 0. So instead of assuming any value other than SW_ANY(0xFD) is unsupported, explictly check if shared_type is SW_ALL and then bail.

cpufreq: CPPC: Delete an unnecessary check before the function call kfree()

2015-11-06T23:03:18Z

The kfree() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

ACPI / CPPC: Add a CPUFreq driver for use with CPPC

2015-10-12T21:04:31Z

This driver utilizes the methods introduced in a previous patch titled - "ACPI: Introduce CPU performance controls using CPPC" and enables usage with existing CPUFreq governors. Signed-off-by: Ashwin Chaugule Reviewed-by: Al Stone Signed-off-by: Rafael J. Wysocki
