[PATCH 00/12] PM / OPP: Use kref and move away from RCU locking

by Viresh Kumar

Hi Rafael, You can pretty much ignore this series until all other OPP cleanup/fixes get merged. I am posting these to get early reviews from Stephen as these patches have been lying with me for almost a week now. And I am also _not_ pushing these for 4.10-rc1. It all depends on how the reviews go. The RCU locking isn't well suited for the OPP core. The RCU locking fits better for reader heavy stuff, while the OPP core have at max one or two readers only at a time. Over that, it was getting very confusing the way RCU locking was used within the OPP core. The individual OPPs are mostly well handled, i.e. for an update a new structure was created and then that replaced the older one. But the OPP tables were updated directly all the time from various parts of the core. Though they were mostly used from within RCU locked region, they didn't had much to do with RCU and were governed by the mutex instead. And that mixed with the 'opp_table_lock' has made the core even more confusing. Similar concerns were shared by Stephen Boyd earlier [1]. This patchset simplifies the locking in OPP core to great extent using Kernel reference counting mechanism along with per OPP table mutex. And finally it gets rid of RCU locking as well. Each and every patch of this series is individually: - build tested - boot tested with cpufreq-dt.ko module. Insmod and rmmod to make sure the OPPs and the OPP tables are getting freed. More testing is also done by various build and boot bots for last few days. And they reported lots of issues (both build and boot time) that helped making this series more robust: - Kernel CI (Linaro) - Fengguang Wu's bot (Intel) This series has few dependencies though. It is rebased over: pm/bleeding-edge + OPP cleanup series [2] + few devfreq fixes [3], [4], and [5]. + A recent revert [6] Though all of those shall get merged before we end up reviewing this series. -- viresh [1] https://marc.info/?l=linux-kernel&m=147742717527548&w=2 [2] https://marc.info/?l=linux-pm&m=148108573618896&w=2 [3] https://patchwork.kernel.org/patch/9455789/ [4] https://patchwork.kernel.org/patch/9455757/ [5] https://marc.info/?l=linux-pm&m=148090824301852&w=2 [6] https://marc.info/?l=linux-kernel&m=148110674223377&w=2 Viresh Kumar (12): PM / OPP: Add per OPP table mutex PM / OPP: Add 'struct kref' to OPP table PM / OPP: Return opp_table from dev_pm_opp_set_*() routines PM / OPP: Take reference of the OPP table while adding/removing OPPs PM / OPP: Use dev_pm_opp_get_opp_table() instead of _add_opp_table() PM / OPP: Add 'struct kref' to struct dev_pm_opp PM / OPP: Update OPP users to put reference PM / OPP: Take kref from _find_opp_table() PM / OPP: Move away from RCU locking PM / OPP: Simplify _opp_set_availability() PM / OPP: Simplify dev_pm_opp_get_max_volt_latency() PM / OPP: Update Documentation to remove RCU specific bits Documentation/power/opp.txt | 47 +- arch/arm/mach-omap2/pm.c | 5 +- drivers/base/power/opp/core.c | 888 +++++++++++------------------------ drivers/base/power/opp/cpu.c | 66 +-- drivers/base/power/opp/of.c | 94 +--- drivers/base/power/opp/opp.h | 31 +- drivers/clk/tegra/clk-dfll.c | 17 +- drivers/cpufreq/exynos5440-cpufreq.c | 5 +- drivers/cpufreq/imx6q-cpufreq.c | 10 +- drivers/cpufreq/mt8173-cpufreq.c | 8 +- drivers/cpufreq/omap-cpufreq.c | 4 +- drivers/cpufreq/sti-cpufreq.c | 13 +- drivers/devfreq/devfreq.c | 14 +- drivers/devfreq/exynos-bus.c | 14 +- drivers/devfreq/governor_passive.c | 4 +- drivers/devfreq/rk3399_dmc.c | 16 +- drivers/devfreq/tegra-devfreq.c | 4 +- drivers/thermal/cpu_cooling.c | 11 +- drivers/thermal/devfreq_cooling.c | 14 +- include/linux/pm_opp.h | 48 +- 20 files changed, 429 insertions(+), 884 deletions(-) -- 2.7.1.410.g6faf27b

[PATCH v8 0/8] Add PWM and IIO timer drivers for STM32

by Benjamin Gaignard

version 8: - rebase on v4.10-rc4 - fix comments done by Thierry on PWM - reword "reg" parameter description - change kernel kernel in IIO ABI documentation version 7: - rebase on v4.10-rc2 - remove iio_device code from driver and keep only the trigger part version 6: - rename stm32-gptimer in stm32-timers. - change "st,stm32-gptimer" compatible to "st,stm32-timers". - modify "st,breakinput" parameter in pwm part. - split DT patch in 2 version 5: - fix comments done on version 4 - rebased on kernel 4.9-rc8 - change nodes names and re-order then by addresses version 4: - fix comments done on version 3 - don't use interrupts anymore in IIO timer - detect hardware capabilities at probe time to simplify binding version 3: - no change on mfd and pwm divers patches - add cross reference between bindings - change compatible to "st,stm32-timer-trigger" - fix attributes access rights - use string instead of int for master_mode and slave_mode - document device attributes in sysfs-bus-iio-timer-stm32 - update DT with the new compatible version 2: - keep only one compatible per driver - use DT parameters to describe hardware block configuration: - pwm channels, complementary output, counter size, break input - triggers accepted and create by IIO timers - change DT to limite use of reference to the node - interrupt is now in IIO timer driver - rename stm32-mfd-timer to stm32-timers (for general purpose timer) The following patches enable PWM and IIO Timer features for STM32 platforms. Those two features are mixed into the registers of the same hardware block (named general purpose timer) which lead to introduce a multifunctions driver on the top of them to be able to share the registers. In STM32f4 14 instances of timer hardware block exist, even if they all have the same register mapping they could have a different number of pwm channels and/or different triggers capabilities. We use various parameters in DT to describe the differences between hardware blocks The MFD (stm32-timers.c) takes care of clock and register mapping by using regmap. stm32_timers structure is provided to its sub-node to share those information. PWM driver is implemented into pwm-stm32.c. Depending of the instance we may have up to 4 channels, sometime with complementary outputs or 32 bits counter instead of 16 bits. Some hardware blocks may also have a break input function which allows to stop pwm depending of a level, defined in devicetree, on an external pin. IIO timer driver (stm32-timer-trigger.c and stm32-timer-trigger.h) define a list of hardware triggers usable by hardware blocks like ADC, DAC or other timers. The matrix of possible connections between blocks is quite complex so we use trigger names and is_stm32_iio_timer_trigger() function to be sure that triggers are valid and configure the IPs. At run time IIO timer hardware blocks can configure (through "master_mode" IIO device attribute) which internal signal (counter enable, reset, comparison block, etc...) is used to generate the trigger.

[RFC simple allocator v1 0/2] Simple allocator

by Benjamin Gaignard

Hi all, before sending this RFC to a larger audience I would like to get our opinion about it. Please feel very free to comment it, thanks ! The goal of this RFC is to understand if a common ioctl for specific memory regions allocations is needed/welcome. Obviously it will not replace allocation done in linux kernel frameworks like v4l2 or dmr/kms, but offer an alternative when you don't want/need to use them for buffer allocation. "Unix Device Memory Allocator" project [1] wants to create a userland library which may allow to select, depending of the devices constraint, the best back-end for allocation. With this RFC I would to propose to have common ioctl for a maximum of allocator to avoid to duplicated back-end for this library. Since the beginning it is a problem to allocate contiguous memory (CMA) without using v4l2 or drm/kms so the first allocator available in this RFC use CMA memory. An other question is: do we have others memory regions that could be interested by this new framework ? I have in mind that some title memory regions could use it or replace ION heaps (system, carveout etc...). Maybe it only solve CMA allocation issue, in this case no need to create a common ioctl, a custom should be enough. Maybe the first thing to do is to change the name and the location of this module, suggestions are welcome.
