[PATCH] PM / OPP: Make OPP invisible to users in Kconfig

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The OPP code is an in kernel library selected by its users, there is no no architecture code required to implement it and enabling it without a user just increases the kernel size. Since the users select rather than depend on it just remove the ability to directly set the option from Kconfig. Signed-off-by: Mark Brown <broonie(a)linaro.org> --- This leaves the ARCH_HAS_OPP symbol since removing that requires updating the relevant architectures, if this is OK I can sumbit a followup patch cleaning that up. kernel/power/Kconfig | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/kernel/power/Kconfig b/kernel/power/Kconfig index 2fac9cc79b3d..9a83d780facd 100644 --- a/kernel/power/Kconfig +++ b/kernel/power/Kconfig @@ -257,8 +257,7 @@ config ARCH_HAS_OPP bool config PM_OPP - bool "Operating Performance Point (OPP) Layer library" - depends on ARCH_HAS_OPP + bool ---help--- SOCs have a standard set of tuples consisting of frequency and voltage pairs that the device will support per voltage domain.

[PATCH v3 0/2] context tracker support for arm64

by Larry Bassel

Implement and enable context tracking for arm64 (which is a prerequisite for FULL_NOHZ support). This patchset builds upon earlier work by Kevin Hilman and is based on 3.15-rc2. Changes v2 to v3: * Save/restore necessary registers in ct_user_enter and ct_user_exit * Annotate "error paths" out of el0_sync with ct_user_exit Changes v1 to v2: * Save far_el1 in x26 temporarily Larry Bassel (2): arm64: adjust el0_sync so that a function can be called arm64: enable context tracking arch/arm64/Kconfig | 1 + arch/arm64/include/asm/thread_info.h | 1 + arch/arm64/kernel/entry.S | 76 ++++++++++++++++++++++++++++++++---- 3 files changed, 70 insertions(+), 8 deletions(-) -- 1.8.3.2

[PATCH] cpufreq: cpufreq-cpu0: remove dependency on thermal

by Viresh Kumar

cpufreq-cpu0 uses thermal framework to register a cooling device, but doesn't depend on it as there are dummy calls provided by thermal layer when CONFIG_THERMAL=n. So, we don't really need to mention thermal as a dependency for cpufreq-cpu0 in Kconfig. Remove it.

[PATCH V2 0/3] cpufreq: add support for intermediate (stable)

by Viresh Kumar

Douglas Anderson, recently pointed out an interesting problem due to which udelay() was expiring earlier than it should. While transitioning between frequencies few platforms may temporarily switch to a stable frequency, waiting for the main PLL to stabilize. For example: When we transition between very low frequencies on exynos, like between 200MHz and 300MHz, we may temporarily switch to a PLL running at 800MHz. No CPUFREQ notification is sent for that. That means there's a period of time when we're running at 800MHz but loops_per_jiffy is calibrated at between 200MHz and 300MHz. And so udelay behaves badly. To get this fixed in a generic way, lets introduce another set of callbacks get_intermediate() and target_intermediate(), only for drivers with target_index() and CPUFREQ_ASYNC_NOTIFICATION unset. get_intermediate should return a stable intermediate frequency platform wants to switch to, and target_intermediate() should set CPU to to that frequency, before jumping to the frequency corresponding to 'index'. Core will take care of sending notifications and driver doesn't have to handle them in target_intermediate() or target_index(). This patchset also update Tegra to use this new infrastructure. NOTE: Once set to intermediate frequency, driver isn't expected to fail for the following ->target_index() call, if it fails core will issue a WARN(). @Stephen: Can you please test this? I haven't as I didn't had a board. :) V1-V2: Almost changed completely, V1 was here: https://lkml.org/lkml/2014/5/15/40 Viresh Kumar (3): cpufreq: handle calls to ->target_index() in separate routine cpufreq: add support for intermediate (stable) frequencies cpufreq: Tegra: implement intermediate frequency callbacks Documentation/cpu-freq/cpu-drivers.txt | 19 +++++++- drivers/cpufreq/cpufreq.c | 82 ++++++++++++++++++++++++---------- drivers/cpufreq/tegra-cpufreq.c | 81 ++++++++++++++++----------------- include/linux/cpufreq.h | 15 +++++++ 4 files changed, 128 insertions(+), 69 deletions(-) -- 2.0.0.rc2

[PATCH v3] arm64: Support arch_irq_work_raise() via self IPIs

by Larry Bassel

Support for arch_irq_work_raise() was missing from arm64 (a prerequisite for FULL_NOHZ). This patch is based on the arm32 patches ARM 7872/1 and 7887/1. commit bf18525fd793101df42a1344ecc48b49b62e48c9 Author: Stephen Boyd <sboyd(a)codeaurora.org> Date: Tue Oct 29 20:32:56 2013 +0100 ARM: 7872/1: Support arch_irq_work_raise() via self IPIs By default, IRQ work is run from the tick interrupt (see irq_work_run() in update_process_times()). When we're in full NOHZ mode, restarting the tick requires the use of IRQ work and if the only place we run IRQ work is in the tick interrupt we have an unbreakable cycle. Implement arch_irq_work_raise() via self IPIs to break this cycle and get the tick started again. Note that we implement this via IPIs which are only available on SMP builds. This shouldn't be a problem because full NOHZ is only supported on SMP builds anyway.

[RFC] cpufreq: send notifications for intermediate (stable) frequencies

by Viresh Kumar

Douglas Anderson, recently pointed out an interesting problem due to which his udelay() was expiring earlier than it should: https://lkml.org/lkml/2014/5/13/766 While transitioning between frequencies few platforms may temporarily switch to a stable frequency, waiting for the main PLL to stabilize. For example: When we transition between very low frequencies on exynos, like between 200MHz and 300MHz, we may temporarily switch to a PLL running at 800MHz. No CPUFREQ notification is sent for that. That means there's a period of time when we're running at 800MHz but loops_per_jiffy is calibrated at between 200MHz and 300MHz. And so udelay behaves badly. To get this fixed in a generic way, lets introduce another callback safe_freq() for the cpufreq drivers. safe_freq() should return a stable intermediate frequency a platform might want to switch to, before jumping to the frequency corresponding to 'index'. Core will send the 'PRE' notification for this 'stable' frequency and 'POST' for the 'target' frequency. Though if ->target_index() fails, it will handle POST for 'stable' frequency only. Drivers must send 'POST' notification for 'stable' freq and 'PRE' for 'target' freq. If they can't switch to target frequency, they don't need to send any notification.
