MIPS: Loongson 2F: Add CPU frequency scaling support 2009-12-17T01:57:20+00:00 Wu Zhangjin wuzhangjin@gmail.com 2009-11-16T17:32:59+00:00 f8ede0f700f5478851f242f291d203cde54ca6cf Loongson 2F supports CPU clock scaling. When put it into wait mode by setting the frequency as ZERO it will stay in this mode until an external interrupt wakes the CPU again. To enable clock scaling support, an external timer of a known stable rate is required.

Loongson 2F supports CPU clock scaling. When put it into wait mode by
setting the frequency as ZERO it will stay in this mode until an external
interrupt wakes the CPU again.

To enable clock scaling support, an external timer of a known stable rate
is required.

MIPS: Add basic CPUFreq options. 2009-12-17T01:57:20+00:00 Wu Zhangjin wuzhangjin@gmail.com 2009-11-16T17:32:58+00:00 9726b43a4d7aaa5b30f559e78768aeb3d17bc224 This patch adds basic options for MIPS CPUFreq support. Since the cp0 timer's frequency is based on the processor clockrate it can not be used with CPUFReq; an additional external timer is required.
