[PATCH v17 00/15] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code; 4. Rename some enums and defines; 5. Rework PPI determination; 6. Rework counter frequency detection; 7. Refactor arch_timer_needs_probing, move it into DT init call 8. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer. This patchset has been tested on the following platforms with ACPI enabled: (1)ARM Foundation v8 model Changelog: v17: https://lkml.org/lkml/2016/11/25/ Take out some cleanups from 4/15. Merge 5/15 and 6/15, improve PPI determination code, improve commit message. Rework counter frequency detection. Move arch_timer_needs_of_probing into DT init call. Move Platform Timer scan loop back to timer init call to avoid allocating and free memory. Improve all the exported functions' comment. v16: https://lkml.org/lkml/2016/11/16/268 Fix patchset problem about static enum ppi_nr of 01/13 in v15. Refactor arch_timer_detect_rate.

This patchset depends on the following patchset: [UPDATE PATCH V11 1/8] ACPI: I/O Remapping Table (IORT) initial support https://lkml.org/lkml/2016/9/12/949 This patchset has been tested on the following platforms: (1)ARM Foundation v8 model Changelog: v14: https://lkml.org/lkml/2016/9/28/ Separate memory-mapped timer GTDT support into two patches 1. Refactor the timer init code to prepare for GTDT 2. Add GTDT support for memory-mapped timer v13: http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1231717.html Improve arm_arch_timer code for memory-mapped timer GTDT support, refactor original memory-mapped timer dt support for reusing some common code. v12: https://lkml.org/lkml/2016/9/13/250 Rebase to latest Linux 4.8-rc6 Delete the confusing "skipping" in the error message. V11: https://lkml.org/lkml/2016/9/6/354 Rebase to latest Linux 4.8-rc5 Delete typedef (suggested by checkpatch.pl) V10: https://lkml.org/lkml/2016/7/26/215 Drop the "readq" patch. Rebase to latest Linux 4.7. V9: https://lkml.org/lkml/2016/7/25/345 Improve pr_err message in acpi gtdt driver. Update Commit message for 7/9 shorten the irq mapping function name Improve GTDT driver for memory-mapped timer v8: https://lkml.org/lkml/2016/7/19/660 Improve "pr_fmt(fmt)" definition: add "ACPI" in front of "GTDT", and also improve printk message. Simplify is_timer_block and is_watchdog. Merge acpi_gtdt_desc_init and gtdt_arch_timer_init into acpi_gtdt_init(); Delete __init in include/linux/acpi.h for GTDT API Make ARM64 select GTDT. Delete "#include <linux/module.h>" from acpi_gtdt.c Simplify GT block parse code. v7: https://lkml.org/lkml/2016/7/13/769 Move the GTDT driver to drivers/acpi/arm64 Add add the ARM64-specific ACPI Support maintainers in MAINTAINERS Merge 3 patches of GTDT parser driver. Fix the for_each_platform_timer bug. v6: https://lkml.org/lkml/2016/6/29/580 split the GTDT driver to 4 parts: basic, arch_timer, memory-mapped timer, and SBSA Generic Watchdog timer Improve driver by suggestions and example code from Daniel Lezcano v5: https://lkml.org/lkml/2016/5/24/356 Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer. Improve irq info export code to allow missing irq info in GTDT table. v3: https://lkml.org/lkml/2016/2/1/658 Improve GTDT driver code: (1)improve pr_* by defining pr_fmt(fmt) (2)simplify gtdt_sbsa_gwdt_init (3)improve gtdt_arch_timer_data_init, if table is NULL, it will try to get GTDT table. Move enum ppi_nr to arm_arch_timer.h, and add enum spi_nr. Add arm_arch_timer get ppi from DT and GTDT support for kvm. v2: https://lkml.org/lkml/2015/12/2/10 Rebase to latest kernel version(4.4-rc3). Fix the bug about the config problem, use CONFIG_ACPI_GTDT instead of CONFIG_ACPI in arm_arch_timer.c v1: The first upstreaming version: https://lkml.org/lkml/2015/10/28/553 Fu Wei (9): clocksource/drivers/arm_arch_timer: Move enums and defines to header file clocksource/drivers/arm_arch_timer: Add a new enum for spi type clocksource/drivers/arm_arch_timer: Improve printk relevant code acpi/arm64: Add GTDT table parse driver clocksource/drivers/arm_arch_timer: Simplify ACPI support code. acpi/arm64: Add memory-mapped timer support in GTDT driver clocksource/drivers/arm_arch_timer: Refactor the timer init code to prepare for GTDT clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver arch/arm64/Kconfig | 1 + drivers/acpi/arm64/Kconfig | 3 + drivers/acpi/arm64/Makefile | 1 + drivers/acpi/arm64/gtdt.c | 309 ++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 2 +- drivers/clocksource/arm_arch_timer.c | 331 +++++++++++++++++++++-------------- drivers/watchdog/Kconfig | 1 + include/clocksource/arm_arch_timer.h | 32 ++++ include/linux/acpi.h | 7 + 9 files changed, 558 insertions(+), 129 deletions(-) create mode 100644 drivers/acpi/arm64/gtdt.c -- 2.7.4
