[PATCH v3 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 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.

[PATCH 1/3] arm64: topology: Implement basic CPU topology support

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Add basic CPU topology support to arm64, based on the existing pre-v8 code and some work done by Mark Hambleton. This patch does not implement any topology discovery support since that should be based on information from firmware, it merely implements the scaffolding for integration of topology support in the architecture. The goal is to separate the architecture hookup for providing topology information from the DT parsing in order to ease review and avoid blocking the architecture code (which will be built on by other work) with the DT code review by providing something something simple and basic. A following patch will implement support for parsing the DT topology bindings for ARM, similar patches will be needed for ACPI.

[PATCH V4] cpufreq: suspend governors on system suspend/hibernate

by Viresh Kumar

This patch adds cpufreq callbacks to dpm_{suspend|resume}_noirq() for handling suspend/resume of cpufreq governors. There are multiple problems that are fixed by this patch: - Nishanth Menon (TI) found an interesting problem on his platform, OMAP. His board wasn't working well with suspend/resume as calls for removing non-boot CPUs was turning out into a call to drivers ->target() which then tries to play with regulators. But regulators and their I2C bus were already suspended and this resulted in a failure. Many platforms have such problems, samsung, tegra, etc.. They solved it with driver specific PM notifiers where they used to disable their driver's ->target() routine. - Lan Tianyu (Intel) & Jinhyuk Choi (Broadcom) found another issue where tunables configuration for clusters/sockets with non-boot CPUs was getting lost after suspend/resume, as we were notifying governors with CPUFREQ_GOV_POLICY_EXIT on removal of the last cpu for that policy and so deallocating memory for tunables. This is also fixed with this patch as we don't allow any operation on Governors during suspend/resume now.

nohz_full left a periodic tick cpu issue

by Alex Shi

Hi Frederic, Sorry for idiot of nohz_full. When we using this feature on my mobile devices, we found this feature keep cpu0 in periodic tick mode. then the timer interrupt on cpu0 is very higher than normal nohz mode. that cause high power consuming cost. I found you have mention this on commit: a382bf934449 nohz: Assign timekeeping duty to a CPU outside the full dynticks range In fact, if all full dynticks cpu are in idle, cpu0 should be safe to get into idle too. Do you have some plan or idea to implement this? otherwise, power cost is too high to enable nohz_full in mobile platform. -- Thanks Alex

[LSK PATCH] Revert "ARM: bL_switcher: Allow detachment of outstanding switch requests"

by Jon Medhurst (Tixy)

This reverts commit 4725d41daea7e0cc79b3fb92af012b8cb18fccff. This patch was dropped when the big.LITTLE switcher was submitted to the mainline kernel because it wasn't then being used and contained a logical flaw which meant it wouldn't have achieved what it was attempting to do anyway. It can also produce compilation warnings in certain configurations. --- arch/arm/common/bL_switcher.c | 32 -------------------------------- arch/arm/include/asm/bL_switcher.h | 6 ------ 2 files changed, 38 deletions(-) diff --git a/arch/arm/common/bL_switcher.c b/arch/arm/common/bL_switcher.c index 1883c5b..2193ae7 100644 --- a/arch/arm/common/bL_switcher.c +++ b/arch/arm/common/bL_switcher.c @@ -404,38 +404,6 @@ int bL_switch_request_cb(unsigned int cpu, unsigned int new_cluster_id, EXPORT_SYMBOL_GPL(bL_switch_request_cb); /* - * Detach an outstanding switch request. - * - * The switcher will continue with the switch request in the background, - * but the completer function will not be called. - * - * This may be necessary if the completer is in a kernel module which is - * about to be unloaded. - */ -void bL_switch_request_detach(unsigned int cpu, - bL_switch_completion_handler completer) -{ - struct bL_thread *t; - - if (cpu >= ARRAY_SIZE(bL_threads)) { - pr_err("%s: cpu %d out of bounds\n", __func__, cpu); - return; - } - - t = &bL_threads[cpu]; - - if (IS_ERR(t->task) || !t->task) - return; - - spin_lock(&t->lock); - if (t->completer == completer) - t->completer = NULL; - spin_unlock(&t->lock); -} - -EXPORT_SYMBOL_GPL(bL_switch_request_detach); - -/* * Activation and configuration code. */ diff --git a/arch/arm/include/asm/bL_switcher.h b/arch/arm/include/asm/bL_switcher.h index 482383b..87ebcbc 100644 --- a/arch/arm/include/asm/bL_switcher.h +++ b/arch/arm/include/asm/bL_switcher.h @@ -40,9 +40,6 @@ static inline int bL_switch_request(unsigned int cpu, unsigned int new_cluster_i #ifdef CONFIG_BL_SWITCHER -void bL_switch_request_detach(unsigned int cpu, - bL_switch_completion_handler completer); - int bL_switcher_register_notifier(struct notifier_block *nb); int bL_switcher_unregister_notifier(struct notifier_block *nb); @@ -61,9 +58,6 @@ int bL_switcher_trace_trigger(void); int bL_switcher_get_logical_index(u32 mpidr); #else -static void bL_switch_request_detach(unsigned int cpu, - bL_switch_completion_handler completer) { } - static inline int bL_switcher_register_notifier(struct notifier_block *nb) { return 0; -- 1.7.10.4

[RFC PATCH 0/2] arm64: Add support for 48-bit Physical Addresses

by mohun106＠gmail.com

From: Radha Mohan Chintakuntla <rchintakuntla(a)cavium.com> This patch series provides an implementation of supporting 48-bit Physical Addresses for ARMv8 platforms. It is the maximum width that any ARMv8 based processor can support. The implementation extends the existing support of 40-bit PA.The kernel and user space will now be able to access 128TB each. With 4KB page size the Linux now will be using 4 levels of page tables by making use of 'pud'. And with 64KB page size the Linux will be using 3 levels of page tables. The code has been tested with LTP.

[PATCH 0/2] PSCI system off and reset for KVM ARM/ARM64

by Anup Patel

The Power State and Coordination Interface (PSCI) specification defines SYSTEM_OFF and SYSTEM_RESET functions for system poweroff and reboot. This patchset adds emulation of PSCI SYSTEM_OFF and SYSTEM_RESET functions in KVM ARM/ARM64 by forwarding them to user space (QEMU or KVMTOOL) using KVM_EXIT_SHUTDOWN and KVM_EXIT_RESET exit reasons. To try this patch from guest kernel, we will need PSCI-based restart and poweroff support in the guest kenel for both ARM and ARM64. Rob Herring has already submitted patches for PSCI-based restart and poweroff in ARM kernel but these are not merged yet due unstable device tree bindings of kernel PSCI support. We will be having similar patches for PSCI-based restart and poweroff in ARM64 kernel. (Refer http://www.spinics.net/lists/arm-kernel/msg262217.html) (Refer http://www.spinics.net/lists/devicetree/msg05348.html) Anup Patel (2): KVM: Add KVM_EXIT_RESET to user space API header ARM/ARM64: KVM: Forward PSCI SYSTEM_OFF and SYSTEM_RESET to user space arch/arm/include/asm/kvm_psci.h | 2 +- arch/arm/include/uapi/asm/kvm.h | 2 ++ arch/arm/kvm/handle_exit.c | 7 ++++++- arch/arm/kvm/psci.c | 38 +++++++++++++++++++++++++++++-------- arch/arm64/include/asm/kvm_psci.h | 2 +- arch/arm64/include/uapi/asm/kvm.h | 2 ++ arch/arm64/kvm/handle_exit.c | 10 ++++++---- include/uapi/linux/kvm.h | 1 + 8 files changed, 49 insertions(+), 15 deletions(-) -- 1.7.9.5

[PATCH 1/3] ARM: dts: Leave Exynos5250 SPI controller disabled by default

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Rather than requiring each board to explicitly disable the SPI controllers it is not using instead require boards to enable those that they are using. This is less work overall since normally at most one of the controllers is in use and avoids issues caused by inappropriate pinmuxing.

[PATCH 1/2] ASoC: samsung: Provide helper for DMA init

From: Mark Brown <broonie(a)linaro.org> In preparation for using the dmaengine helpers in ASoC rather than the dmaengine wrappers for the Samsung API wrap the configuration of dma_data. The dmaengine code expects different data to that used by the legacy API.

[PATCH v4 0/2] perf: config: add per-feature check flags

by Jean Pihet

Add CFLAGS and LDFLAGS for each feature to be checked during the build. This allows to pass particular flags and parameters to the feature checks compilation. Use the per-feature check flags for the unwinding feature in order to correctly compile the test-all, libunwind and libunwind-debug-frame feature checks. This change set simplifies the flags passing mechanism between the Makefiles in config/Makefile and config/feature-checks; this could be farther optimized by moving the compilation flags to the per-feature check flags for all features to be checked. Tested on x86_64, ARMv7 and ARMv8 with and without LIBUNWIND_DIR set in 'make -C tools/perf' Jean Pihet (2): perf: add per-feature check flags perf: unwinding: use the per-feature check flags tools/perf/config/Makefile | 52 ++++++++++++++++++------------- tools/perf/config/feature-checks/Makefile | 8 ++--- 2 files changed, 34 insertions(+), 26 deletions(-) -- 1.7.11.7

[PATCH v2 0/6] 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 will be coming later but they presume that reduced HW mode is functioning correctly.

[PATCH v3 0/2] perf: config: add per-feature check flags

by Jean Pihet

Add CFLAGS and LDFLAGS for each feature to be checked during the build. This allows to pass particular flags and parameters to the feature checks compilation. Use the per-feature check flags for the unwinding feature in order to correctly compile the libunwind and libunwind-debug-frame feature checks. This change set simplifies the flags passing mechanism between the Makefiles in config/Makefile and config/feature-checks; this could be farther optimized by moving the compilation flags to the per-feature check flags for all features to be checked. Tested on x86_64, ARMv7 and ARMv8 with and without LIBUNWIND_DIR set in 'make -C tools/perf' Jean Pihet (2): perf: add per-feature check flags perf: unwinding: use the per-feature check flags tools/perf/config/Makefile | 48 +++++++++++++++++-------------- tools/perf/config/feature-checks/Makefile | 8 +++--- 2 files changed, 30 insertions(+), 26 deletions(-) -- 1.7.11.7

[RFC part2 PATCH 0/9] Using ACPI MADT table to initialise SMP and GIC

by Hanjun Guo

This patch set is based on part1 "Make ACPI core running on ARM64" patch set. After we can get the ACPI tables from UEFI, we can use these tables to initialise the system now. GIC (means GIC cpu interface) structure and GIC distributor structure in MADT table contains the information of GIC cpu interface base address and GIC distributor base address, which can be used to initialise GIC. Further more, parked address in GIC structure can be used as cpu release address for spin table SMP initialisation. This patch set use these information to init SMP and GIC. Please refer to chapter 5.2.12.14/15 of ACPI 5.0 spec for GIC and GIC distributor structure information.

[PATCH] ARM: topology: Staticise non-exported symbols

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> These symbols are only referenced in this source file so can be made static, and the efficiency table is constant data so can be declared as such. This avoids polluting the global namespace and fixes warnings from sparse. The function arch_scale_freq_power() is still not prototyped or static, this is a separate issue as this is overriding a weak symbol from the scheduler which neglects to provide a prototype.

[RFC part3 PATCH 0/2] Using ACPI GTDT table to initialize arch timer

by Hanjun Guo

This is the last part of patch set for core of ARM64 ACPI, and is based on the patch set part2 "Using ACPI MADT table to initialise SMP and GIC". ACPI GTDT (Generic Timer Description Table) is used for ARM/ARM64 only, and contains the information for arch timer initialisation. This patch trys to convert the arch timer to ACPI using GTDT. After this patch set was posted, we already finished the SMP, GIC and arch timer initialisation, which all are essential for ARM64 core system running, then we will focus on converting the device drivers to ACPI.

[PATCH 1/2] ASoC: samsung: Provide helper for DMA init

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> In preparation for using the dmaengine helpers in ASoC rather than the dmaengine wrappers for the Samsung API wrap the configuration of dma_data. The dmaengine code expects different data to that used by the legacy API.

[PATCH CFT] ARM:MSM: Enable ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR default

by panchaxari

ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR have been enabled as default configs to MSM platform Introduction of PHYS_VIRT config as default would enable phy-to-virt and virt-to-phy translation function at boot and module loading time and enforce dynamic reallocation of memory. AUTO_ZRELADDR config would enable calculation of kernel load address at run time. PHYS_VIRT config is mutually exclusive to XIP_KERNEL, XIP_KERNEL is used in systems with NOR flash devices, and ZRELADDR config is mutually exclusive to ZBOOT_ROM. CFT::Call For Testing Requesting maintainers of MSM platforms to evaluate the changes on the board and comment, as I dont have the board for testing and also requesting an ACK Signed-off-by: panchaxari <panchaxari.prasannamurthy(a)linaro.org> Cc: David Brown <davidb(a)codeaurora.org> Cc: Daniel Walker <dwalker(a)fifo99.com> Cc: Bryan Huntsman <bryanh(a)codeaurora.org> Cc: Russell King <linux(a)arm.linux.org.uk> Cc: Linus Walleij <linus.walleij(a)linaro.org> Cc: linux-arm-msm(a)vger.kernel.org Cc: linux-arm-kernel(a)lists.infradead.org Cc: linux-kernel(a)vger.kernel.org --- ARCH_MSM supports for Qualcomm MSM/QSD based systems. This runs on the apps processor of the MSM/QSD and depends on a shared memory interface to the modem processor which runs the baseband stack and controls some vital subsystems like clock and power control. Snapdragon is based on ARMv7 instruction set. And supports Random memory devices like DDR1, LPDDR2 and LPDDR3. And storage memory devices like NAND, eMMC.
