Hi Folks, A quick note that I'm poking at a test kernel with ACPI_INITRD_TABLE_OVERRIDE support. I don't condone this for production kernels, but for testing fixes to DSDT's and SSDT's it can be very useful to insert updated tables into the initrd (this is commonplace on x86 during development). If someone already poked at this, let me know if you plan to post something upstream, etc. Jon.

[PATCH 00/11] ARM64 PCI hostbridge init based on ACPI

by Hanjun Guo

This patch set is introducing ARM64 PCI hostbridge init based on ACPI, which based on Jiang Liu's patch set "Consolidate ACPI PCI root common code into ACPI core": https://lkml.org/lkml/2015/5/14/98 This patch set including three parts: - the first part is PATCH 1, which should be merged into Jiang Liu's patch set to fix the compile error on ARM64 when ACPI enabled. - the senconed part is the refactoring of mmconfig to let that mechanism can be used for ARM64 too, it's Tomasz's work but he is moving to other work and pretty busy for now, so I will take care of those patches, Tomasz will show up when some comments need to be addressed :) In this version of mmconfig refactor patches, I removed the rename of mmconfig -> ecam patch, because mmconfig is in multi places, and need much more effort to convert them all to ecam, Bjorn, if you don't like it, I can add them back. - The third part is about the ARM64 PCI hostbridge init based on ACPI, first I fixed a compile error for XEN PCI on ARM64 when PCI_MMCONFIG=y, and then introduce PCI init based on Jiang Liu and Tomasz's patch set. patch for ARM64 ACPI PCI still reserve the bus sysdata to get the domain number, because Yijing's patch set is still under review, will be removed when Yijing's patch set hits upstream. This patch set was tested by Suravee on Seattle board with legacy interrupt (not MSI), and it works, also tested on qemu by Graeme. You can get the code from: git://git.linaro.org/leg/acpi/acpi.git, devel branch Comments are welcomed.

[PATCH v8 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 "pretimeout" into the watchdog framework, and update Documentation/watchdog/watchdog-kernel-api.txt to introduce: (1)the new elements in the watchdog_device and watchdog_ops struct; (2)the new API "watchdog_init_timeouts". (3)Introduce ARM SBSA watchdog driver: a.Use linux kernel watchdog framework; b.Work with FDT on ARM64; c.Use "pretimeout" in watchdog framework; d.Support getting timeout and pretimeout from parameter and FDT at the driver init stage. e.In the first timeout, do panic to save system context; f.In the second stage, user can still feed the dog without cleaning WS0. By this feature, we can avoid the panic infinite loops, while backing up a large system context in a server. g.In the second stage, can trigger WS1 by setting pretimeout = 0 if necessary. This patchset has been tested with watchdog daemon (ACPI/FDT, module/build-in) on the following platforms: (1)ARM Foundation v8 model (2)AMD Seattle platform This patchset has been tested with kdump successfully. Changelog: v8: 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: 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: 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: 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: 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: 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: 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: The first version upstream patchset to linux mailing list.

[RESEND PATCH 0/3] ACPI compliance testing for MADT and its subtables

by Al Stone

This patch series adds in specific ACPI compliance testing for the MADT and all of its various subtables (16, currently). The first patch adds tests for the MADT and all subtables currently defined in FWTS. The last two patches add in the relatively new GIC ITS subtable and compliance tests for it. There are still multiple TODOs in the compliance checks; these will be added as clarification of the spec becomes available.

[PATCH] ACPI: MADT: further update to GICC flag checks for 6.0

by Al Stone

In a previous patch ("ACPI: MADT: update GICC flag checks for ACPI 6.0"), I corrected the flag mask used in the if test, but failed to correct the flag used in the fwts_failed() call that was part of the logic block. This patch fixes the mask for fwts_failed() so the test and failure message are consistent again.

[PATCH v9 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 "pretimeout" into the watchdog framework, and update Documentation/watchdog/watchdog-kernel-api.txt to introduce: (1)the new elements in the watchdog_device and watchdog_ops struct; (2)the new API "watchdog_init_timeouts". (3)Introduce ARM SBSA watchdog driver: a.Use linux kernel watchdog framework; b.Work with FDT on ARM64; c.Use "pretimeout" in watchdog framework; d.Support getting timeout and pretimeout from parameter and FDT at the driver init stage. e.In the first timeout, do panic to save system context; f.In the second stage, user can still feed the dog without cleaning WS0. By this feature, we can avoid the panic infinite loops, while backing up a large system context in a server. g.In the second stage, can trigger WS1 by setting pretimeout = 0 if necessary. This patchset has been tested with watchdog daemon (ACPI/FDT, module/build-in) on the following platforms: (1)ARM Foundation v8 model (2)AMD Seattle platform This patchset has been tested with kdump successfully. Changelog: v9: 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: 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: 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: 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: 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: 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: 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: 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: 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: introdouce "pretimeout" into framework Watchdog: introduce ARM SBSA watchdog driver .../devicetree/bindings/watchdog/sbsa-gwdt.txt | 34 ++ Documentation/watchdog/watchdog-kernel-api.txt | 61 ++- Documentation/watchdog/watchdog-parameters.txt | 6 + arch/arm64/boot/dts/amd/amd-seattle-soc.dtsi | 8 + arch/arm64/boot/dts/arm/foundation-v8.dts | 7 + drivers/watchdog/Kconfig | 14 + drivers/watchdog/Makefile | 1 + drivers/watchdog/sbsa_gwdt.c | 459 +++++++++++++++++++++ drivers/watchdog/watchdog_core.c | 127 ++++-- drivers/watchdog/watchdog_dev.c | 53 +++ include/linux/watchdog.h | 39 +- 11 files changed, 767 insertions(+), 42 deletions(-) create mode 100644 Documentation/devicetree/bindings/watchdog/sbsa-gwdt.txt create mode 100644 drivers/watchdog/sbsa_gwdt.c -- 2.5.0
