[PATCH v4 0/5] Hardware Reduced Mode Cleanup for ACPI

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> This series of patches starts with Hanjun's patch to create a kernel config item for CONFIG_ACPI_REDUCED_HARDWARE [0]. Building on that, I then reviewed all of the code that touched any of several fields in the FADT that the OSPM is supposed to ignore when ACPI is in Hardware Reduced mode [1]. Any time there was a use of one of the fields to be ignored, I evaluated whether or not the code was implementing Hardware Reduced mode correctly. Similarly, for each the flags in the FADT flags field that are to be ignored in Hardware Reduced mode, the kernel code was again scanned for proper usage. The remainder of the patches are to fix all of the situations I could find where the kernel would not behave correctly in this ACPI mode. These seem to work just fine on the RTSM model for ARMv7, both with and without ACPI enabled, and with and without ACPI_REDUCED_HARDWARE enabled; similarly for the FVP model for ARMv8. The patches for ACPI on ARM hardware have been submitted elsewhere but they presume that reduced HW mode is functioning correctly. In the meantime, there's no way I can think of to test all possible scenarios so feedback would be greatly appreciated. [0] List at https://wiki.linaro.org/LEG/Engineering/Kernel/ACPI/AcpiReducedHw#Section_5… [1] Please see the ACPI Specification v5.0 for details on Hardware Reduced mode (sections 3.11.1, 4.1, 5.2.9, at a minimum). Changes for v4: -- Given the current state of ACPICA, disable CONFIG_ACPI_REDUCED_HARDWARE for use on anything other than ARM. -- Replaced #ifdefs with run-time checking for hardware reduced mode, whenever possible Changes for v3: -- Modified enabling ACPI_REDUCED_HARDWARE in ACPICA when using kernel config item CONFIG_ACPI_REDUCED_HARDWARE; now consistent with ACPICA code base where needed -- Enable X86 for CONFIG_ACPI_REDUCED_HARDWARE -- Minimize bus master reload patching -- Remove unneeded patch for dmi_check_system() (was 4/6) -- Correct the patch for removing unneeded map/unmap of FADT fields Changes for v2: -- Remove patch that was outside of reduced HW mode changes -- Simplify CONFIG_ACPI_REDUCED_HARDWARE in Kconfig -- Simplify use of CONFIG_ACPI_REDUCED_HARDWARE in #ifdefs -- Ensure changelogs are present -- Combine and simplify previous patches 8 & 10 Al Stone (5): ACPI: introduce CONFIG_ACPI_REDUCED_HARDWARE to enable this ACPI mode ACPI: bus master reload not supported in reduced HW mode ACPI: HW reduced mode does not allow use of the FADT sci_interrupt field ACPI: in HW reduced mode, using FADT PM information is not allowed. ACPI: do not map/unmap memory regions for FADT entries in reduced HW mode drivers/acpi/Kconfig | 8 ++++++++ drivers/acpi/bus.c | 30 ++++++++++++++++-------------- drivers/acpi/osl.c | 38 +++++++++++++++++++------------------- drivers/acpi/pci_link.c | 2 ++ drivers/acpi/processor_idle.c | 14 ++++++++++++-- include/acpi/platform/aclinux.h | 6 ++++++ 6 files changed, 63 insertions(+), 35 deletions(-) -- 1.8.3.1

[PATCH 0/4] CPUFreq stats: Bug fixes

by Viresh Kumar

Hi Rafael, I know you asked me not to send any more patches before the earlier ones get into kernel. I got to this as Nicolas Pitre required to send few CPUFreq patches for ARM's big LITTLE In-Kernel-Switcher. And within linaro we have hacked these bugs in a bad way.. Because of his dependency I am forced to send these.. These aren't introduced recently and so they can be included in 3.13. There are several problems/bugs in cpufreq-stats specially with cpufreq drivers as modules and suspend/resume path. These are mentioned well in changelogs. These are tested over my thinkpad (acpi-cpufreq) in following way: [1] offline+online all CPUs except boot cpu in a while loop [2] then do suspend resume [3] repeat [1] and [2] several times. No issues found.. Also tested on my exynos board: - Added cpufreq_unregister/register while loop in exynos-cpufreq.c so that we continuously register/unregister driver... Stats were working fine now.. - Compile cpufreq-stats as module and insert/remove it several times after removing above hack (as that doesn't let linux boot :) ).. @Srivatsa: You also have fairly good idea of cpufreq now, so please give some time to review this :) @Nico: Can you remove the hacky code from IKS tree and test these instead to see if we still have any issues? -- viresh Viresh Kumar (4): cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly cpufreq: stats: remove hotplug notifiers cpufreq: stats: free table and remove sysfs entry in a single routine cpufreq: stats: create sysfs entries when cpufreq_stats is a module drivers/cpufreq/cpufreq.c | 5 ++ drivers/cpufreq/cpufreq_stats.c | 109 ++++++++++++++++++---------------------- include/linux/cpufreq.h | 2 + 3 files changed, 55 insertions(+), 61 deletions(-) -- 1.7.12.rc2.18.g61b472e

[PATCH 0/7] sched: cleanup trigger_load_balance

by Daniel Lezcano

This patchset does a cleanup on the parameters passed from the function 'trigger_load_balance' to the underneath functions. The cpu is passed as parameter to the different functions as well as the struct rq but this one contains already the cpu information. Moreover, in the call stack for these functions, we have the struct rq retrieved from the cpu, and then the cpu retrieve from the struct rq, etc ... The patchset unifies all these functions to have a struct rq parameter and removes the pointless parameters. -static inline int find_new_ilb(int call_cpu) +static inline int find_new_ilb(void) -static void nohz_balancer_kick(int cpu) +static void nohz_balancer_kick(void) -static void rebalance_domains(int cpu, enum cpu_idle_type idle) +static void rebalance_domains(struct rq *rq, enum cpu_idle_type idle) -static void nohz_idle_balance(int this_cpu, enum cpu_idle_type idle) +static void nohz_idle_balance(struct rq *this_rq, enum cpu_idle_type idle) -static inline int nohz_kick_needed(struct rq *rq, int cpu) +static inline int nohz_kick_needed(struct rq *rq) -static inline int on_null_domain(int cpu) +static inline int on_null_domain(struct rq *rq) Daniel Lezcano (7): sched: reduce nohz_kick_needed parameters sched: pass struct rq to on_null_domain function sched: remove unused parameter for find_new_ilb sched: remove unused parameter in nohz_balancer_kick function sched: pass struct rq to rebalance_domains function sched: pass struct rq to nohz_idle_balance function sched: factor out on_null_domain check in trigger_load_balance function kernel/sched/fair.c | 45 ++++++++++++++++++++++----------------------- 1 file changed, 22 insertions(+), 23 deletions(-) -- 1.7.9.5

[RESEND PATCH v2] mfd: twl6030: Fix endianness problem in IRQ handler
