From: Jean Pihet <j-pihet@xxxxxx> Rework the cpuidle code: - optimize the cpuidle C-states data registration and storage, - change the interaction with the debugfs 'enable_off_mode' knob and the use of the C-states 'valid' internal field, - remove dead code, - improve code readability. Tested on Beagleboard B5 with cpuidle in RET and OFF modes. Another 161 lines of OMAP code gone ;p Notes: 1) the debugfs 'enable_off_mode' knob will be deprecated by the use of the devices constraints framework to restrict the power domains power modes. 2) the MPU and CORE power domains low power modes are controlled by cpuidle, based on the allowed overall sleep+wake-up latencies and the wake-up latency constraints on the MPU. This is incorrect. The devices constraints framework shall be used instead to control all power domains. ToDo: - integrate cpuidle with the devices constraints framework, when merged in, - refine the latency figures and express them in term of available data from other frameworks (OMAP PM, constaints framework, omap_devices, new VC/VP voltage and DVFS code ...), Jean Pihet (5): OMAP3 cpuidle: remove useless SDP specific timings OMAP3: clean-up mach specific cpuidle data structures OMAP3: cpuidle: re-organize the C-states data OMAP3: cpuidle: code rework for improved readability OMAP3: cpuidle: change the power domains modes determination logic arch/arm/mach-omap2/board-3430sdp.c | 19 -- arch/arm/mach-omap2/board-rx51.c | 15 +- arch/arm/mach-omap2/cpuidle34xx.c | 424 ++++++++++++----------------------- arch/arm/mach-omap2/pm.h | 17 +- arch/arm/mach-omap2/pm34xx.c | 12 - 5 files changed, 163 insertions(+), 324 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
