2015-01-30devfreq: Fix build break of devfreq-event classChanwoo Choi1-0/+1
This patch fixes the build break of the exynos-ppmu driver because Makefile in drivers/devfreq don't include the entry of devfreq-event.c driver. The original patch[1] includes the entry to build devfreq-event.c without the build break. This build break is generated in the process of merging the patch.

2015-01-30PM / devfreq: event: Add devfreq_event classChanwoo Choi7-0/+993
This patch adds a new class in devfreq, devfreq_event, which provides raw data (e.g., memory bus utilization, GPU utilization) for devfreq governors. - devfreq_event device : Provides raw data for a governor of a devfreq device - devfreq device : Monitors device state and changes frequency/voltage of the device using the raw data from its devfreq_event device. A devfreq device dertermines performance states (normally the frequency and the voltage vlues) based on the results its designtated devfreq governor: e.g., ondemand, performance, powersave. In order to give such results required by a devfreq device, the devfreq governor requires data that indicates the performance requirement given to the devfreq device. The conventional (previous) implementatino of devfreq subsystem requires a devfreq device driver to implement its own mechanism to acquire performance requirement for its governor. However, there had been issues with such requirements: 1. Although performance requirement of such devices is usually acquired from common devices (PMU/PPMU), we do not have any abstract structure to represent them properly. 2. Such performance requirement devices (PMU/PPMU) are actual hardware pieces that may be represented by Device Tree directly while devfreq device itself is a virtual entity that are not considered to be represented by Device Tree according to Device Tree folks. In order to address such issues, a devferq_event device (represented by this patch) provides a template for device drivers representing performance monitoring unit, which gives the basic or raw data for preformance requirement, which in turn, is required by devfreq governors. The following description explains the feature of two kind of devfreq class: - devfreq class (existing) : devfreq consumer device use raw data from devfreq_event device for determining proper current system state and change voltage/frequency dynamically using various governors. - devfreq_event class (new) : Provide measured raw data to devfreq device for governor Cc: MyungJoo Ham <[email protected]> Cc: Kyungmin Park <[email protected]> Signed-off-by: Chanwoo Choi <[email protected]> [Commit message rewritten & conflict resolved by MyungJoo] Signed-off-by: MyungJoo Ham <[email protected]>

2015-01-06rcu: Make SRCU optional by using CONFIG_SRCUPranith Kumar1-0/+1
SRCU is not necessary to be compiled by default in all cases. For tinification efforts not compiling SRCU unless necessary is desirable. The current patch tries to make compiling SRCU optional by introducing a new Kconfig option CONFIG_SRCU which is selected when any of the components making use of SRCU are selected. If we do not select CONFIG_SRCU, srcu.o will not be compiled at all. text data bss dec hex filename 2007 0 0 2007 7d7 kernel/rcu/srcu.o Size of arch/powerpc/boot/zImage changes from text data bss dec hex filename 831552 64180 23944 919676 e087c arch/powerpc/boot/zImage : before 829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after so the savings are about ~2000 bytes.

2014-09-29PM / devfreq: Remove ARCH_HAS_OPP completelyPaul Bolle1-1/+0
The Kconfig symbol ARCH_HAS_OPP became redundant in v3.16: commit 049d595a4db3 ("PM / OPP: Make OPP invisible to users in Kconfig") removed the only dependency that used it. Setting it had no effect anymore. So commit 78c5e0bb145d ("PM / OPP: Remove ARCH_HAS_OPP") removed it. For some reason that commit did not remove all select statements for that symbol. These statements are now useless. Remove one from devfreq too. Signed-off-by: Paul Bolle <[email protected]> Signed-off-by: MyungJoo Ham <[email protected]>

2013-07-03drivers: avoid format string in dev_set_nameKees Cook1-1/+1
Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().

2013-06-03PM / devfreq: fix typo "CPU_EXYNOS4.12" twicePaul Bolle1-1/+1
Dependencies on CPU_EXYNOS4212 and CPU_EXYNOS4412 for the "ARM Exynos4210/4212/4412 Memory Bus DEVFREQ Driver" were added in commit 7b4050381127ae11fcfc74a106d715a5fbbf888a ("PM/Devfreq: Add Exynos4-bus device DVFS driver for Exynos4210/4212/4412."). The tree (at that time, v3.3, and currently) makes clear that this should have been dependencies on SOC_EXYNOS4212 and SOC_EXYNOS4412. Signed-off-by: Paul Bolle <[email protected]>
