[PATCH 0/3] rasdaemon: minor fixes from Debian packaging

by Al Stone

In order to get rasdaemon packaging to work well in Debian, I had to make a few minor fixes -- a printf missing a "%s", a manpage in the wrong section, and a dependency on having system logging running before starting the daemon itself. These are the patches for those fixes (they're already in the 0.5.6 Debian package). Al Stone (3): rasdaemon: correct a printf that was missing a field to print to rasdaemon: the man page should be section 8 not 1 rasdaemon: make sure daemon does not start until after logging does configure.ac | 2 +- man/Makefile.am | 2 +- man/rasdaemon.1.in | 67 ----------------------------------------------- man/rasdaemon.8.in | 67 +++++++++++++++++++++++++++++++++++++++++++++++ mce-intel-p4-p6.c | 2 +- misc/rasdaemon.service.in | 1 - 6 files changed, 70 insertions(+), 71 deletions(-) delete mode 100644 man/rasdaemon.1.in create mode 100644 man/rasdaemon.8.in -- 2.5.0

[PATCH v10 0/5] Watchdog: introduce ARM SBSA watchdog driver

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Introduce Documentation/devicetree/bindings/watchdog/sbsa-gwdt.txt for FDT info of SBSA Generic Watchdog, and give two examples of adding SBSA Generic Watchdog device node into the dts files: foundation-v8.dts and amd-seattle-soc.dtsi. (2)Introduce ARM SBSA watchdog driver: a.Use linux kernel watchdog framework; b.Work with FDT on ARM64; c.Support getting timeout from parameter and FDT at the driver init stage. d.Separate the driver to two parts: (1) single stage timeout driver(ignore WS0 interrupt) (2) register WS0 interrupt for the half timeout panic e.Timeout is from watchdog enabled to WS1 triggered. User can disable "half timeout panic" by kernel config or module parameter panic_enabled. Changelog: v10:Delete pretimeout support Separate the driver to two parts: (1) single stage timeout driver(ignore WS0 interrupt) (2) register WS0 interrupt for the half timeout panic timeout == (enable --> WS1) v9: https://lkml.org/lkml/2015/11/9/57 Rebase to latest kernel version(4.3). Update the Documentation of sbsa-gwdt device node info of FDT: (1) move some introduction to pretimeout patch (2) delete WS1 value from "interrupts" of binding documentation, since WS1 won't be handled by Linux. v8: https://lkml.org/lkml/2015/10/27/466 Rebase to latest kernel version(4.3-rc7). Separate the patches of GTDT support and arm_arch_timer. This clocksource relevant patch will upstreamed in a individual patchset. Update all the default timeout and pretimeout to 30s and 60s. Improve documentation and inline comments. Fix a bug in pretimeout support which makes timeout and pretimeout parameters initialization fail. v7: https://lkml.org/lkml/2015/8/24/611 Rebase to latest kernel version(4.2-rc7). Improve FDT support: geting resource by order, instead of name. According to the FDT support, Update the example dts file, gtdt.c and sbsa_gwdt.c. Pass the sparse test, and fix the warning. Fix the max_pretimeout and max_timeout value overflow bug. Delete the WCV output value. v6: https://lkml.org/lkml/2015/6/23/359 Improve the dtb example files: reduce the register frame size to 4K. Improve pretimeout support: (1) improve watchdog_init_timeouts function (2) rename watchdog_check_min_max_timeouts back to the original name (1) improve watchdog_timeout_invalid/watchdog_pretimeout_invalid Add the new features in the sbsa_gwdt driver: (1) In the second stage, user can feed the dog without cleaning WS0. (2) In the second stage, user can trigger WS1 by setting pretimeout = 0. (3) expand the max value of pretimeout, in case 10 second is not enough for a kdump kernel reboot in panic. v5: https://lkml.org/lkml/2015/6/10/357 Improve pretimeout support: (1)fix typo in documentation and comments. (2)fix the timeout limits validation bug. Simplify sbsa_gwdt driver: (1)integrate all the registers access functions into caller. v4: https://lkml.org/lkml/2015/6/2/4 Refactor GTDT support code: remove it from arch/arm64/kernel/acpi.c, put it into drivers/acpi/gtdt.c file. Integrate the GTDT code of drivers/clocksource/arm_arch_timer.c into drivers/acpi/gtdt.c. Improve pretimeout support, fix "pretimeout == 0" problem. Simplify sbsa_gwdt driver: (1)timeout/pretimeout limits setup; (2)keepalive function; (3)delete "clk == 0" check; (4)delete WS0 status bit check in interrupt routine; (5)sbsa_gwdt_set_wcv function. v3: https://lkml.org/lkml/2015/5/25/111 Delete "export arch_timer_get_rate" patch. Driver back to use arch_timer_get_cntfrq. Improve watchdog_init_timeouts function and update relevant documentation. Improve watchdog_timeout_invalid and watchdog_pretimeout_invalid. Improve foundation-v8.dts: delete the unnecessary tag of device node. Remove "ARM64 || COMPILE_TEST" from Kconfig. Add comments in arch/arm64/kernel/acpi.c Fix typoes and incorrect comments. v2: https://lkml.org/lkml/2015/5/21/172 Improve watchdog-kernel-api.txt documentation for pretimeout support. Export "arch_timer_get_rate" in arm_arch_timer.c. Add watchdog_init_timeouts API for pretimeout support in framework. Improve suspend and resume foundation in driver Improve timeout/pretimeout values init code in driver. Delete unnecessary items of the sbsa_gwdt struct and #define. Delete all unnecessary debug info in driver. Fix 64bit division bug. Use the arch_timer interface to get watchdog clock rate. Add MODULE_DEVICE_TABLE for platform device id. Fix typoes. v1: https://lkml.org/lkml/2015/5/15/279 The first version upstream patchset to linux mailing list. Fu Wei (5): Documentation: add sbsa-gwdt driver documentation ARM64: add SBSA Generic Watchdog device node in foundation-v8.dts ARM64: add SBSA Generic Watchdog device node in amd-seattle-soc.dtsi Watchdog: introduce ARM SBSA watchdog driver Watchdog: ARM SBSA Generic Watchdog half timeout panic support .../devicetree/bindings/watchdog/sbsa-gwdt.txt | 35 ++ Documentation/watchdog/watchdog-parameters.txt | 6 + arch/arm64/boot/dts/amd/amd-seattle-soc.dtsi | 9 + arch/arm64/boot/dts/arm/foundation-v8.dts | 8 + drivers/watchdog/Kconfig | 27 ++ drivers/watchdog/Makefile | 1 + drivers/watchdog/sbsa_gwdt.c | 366 +++++++++++++++++++++ 7 files changed, 452 insertions(+) create mode 100644 Documentation/devicetree/bindings/watchdog/sbsa-gwdt.txt create mode 100644 drivers/watchdog/sbsa_gwdt.c -- 2.5.0

[PATCH V2 0/4] acpi: cppc optimization patches

by Prashanth Prakash

Changes in V2: Fixed compilation error on i386 This series introduces changes to reduce the time required to send a frequency transition requests to the platform while using the cppc-cpufreq driver. With these changes we see significant improvement in the average time to send freq. transition request to the platform. Profiling on an ARM platform showed that the average transaction time per request reduced from 200us to under 20us.

[PATCH V3 00/21] MMCONFIG refactoring and support for ARM64 PCI hostbridge init based on ACPI

by Tomasz Nowicki

>From the functionality point of view this series might be split into the following logic parts: 1. Make MMCONFIG code arch-agnostic which allows all architectures to collect PCI config regions and used when necessary. 2. Move non-arch specific bits to the core code. 3. Use MMCONFIG code and implement generic ACPI based PCI host controller driver. 4. Enable above driver on ARM64 Patches has been built on top of 4.4 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v3) NOTE, this patch set depends on Matthew's patches: http://www.spinics.net/lists/linux-pci/msg45950.html https://github.com/Vality/linux/tree/pci-fixes This has been tested on Cavium ThunderX server and QEMU. Any help in reviewing and testing is very appreciated. v2 -> v3 - fix legacy IRQ assigning and IO ports registration - remove reference to arch specific companion device for ia64 - move ACPI PCI host controller driver to pci_root.c - drop generic domain assignment for x86 and ia64 as I am not able to run all necessary test variants - drop patch which cleaned legacy IRQ assignment since it belongs to Mathew's series: https://patchwork.ozlabs.org/patch/557504/ - extend MCFG quirk code - rebased to 4.4 v1 -> v2 - moved non-arch specific piece of code to dirver/acpi/ directory - fixed IO resource handling - introduced PCI config accessors quirks matching - moved ACPI_COMPANION_SET to generic code Liu Jiang (1): ACPI, PCI: Refine the way to handle translation_offset for ACPI resources Tomasz Nowicki (20): x86, pci: Reorder logic of pci_mmconfig_insert() function x86, pci, acpi: Move arch-agnostic MMCONFIG (aka ECAM) and ACPI code out of arch/x86/ directory pci, acpi, mcfg: Provide generic implementation of MCFG code initialization. x86, pci: mmconfig_{32,64}.c code refactoring - remove code duplication. x86, pci, ecam: mmconfig_64.c becomes default implementation for ECAM driver.
