[RFC PATCH] irqchip / gicv3 / ACPI: Add GICR support via GICC structures

by Hanjun Guo

On systems supporting GICv3 and above, the field of GICR Base Address holds the 64-bit physical address of the associated Redistributor if the GIC Redistributors are not in the always-on power domain, so instead of init GICR regions via GIC redistributor stricture, init it with GICR base address in GICC structures.

I think this can be dealt with easily as long as all platforms observe the rule that if a bit is reserved, the bit should be set a '0' instead of being set randomly.

This will be painful > because we hardwired the old sizes into extlog_mem_event in <ras/ras_event.h> The old size is encoded in "stuct cper_mem_err_compact", other members of the trace data are the same between "Memory Error Section" and "Memory Error Section 2". One option we have without having to disturb user space handler of memory error trace data would be to change "struct cper_mem_err_compact" so the affected elements are of __u32 instead of __u16. Drawback of this option is that the trace buffer will be unnecessarily bigger if a platform generates "Memory Error Section" data instead of "Memory Error Section 2" data. Such drawback is not a big issue given that uncorrected memory error happens infrequently and corrected memory error should be grouped by platform. -- Jonathan (Zhixiong) Zhang The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project

[PATCH non-pretimeout 0/7] 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 ACPI GTDT parser: drivers/acpi/gtdt.c Parse SBSA Generic Watchdog Structure in GTDT table of ACPI, and create a platform device with that information. This platform device can be used by This Watchdog driver. drivers/clocksource/arm_arch_timer.c is simplified by this GTDT support. (3)Introduce ARM SBSA watchdog driver: a.Use linux kernel watchdog framework; b.Work with FDT on ARM64; c.In first timeout, do panic to save system context; d.Support getting timeout from parameter and FDT at the driver init stage. This patchset has been tested with watchdog daemon (ACPI/FDT, module/build-in) on the following platforms: (1)ARM Foundation v8 model Changelog: non_pretimeout: Delete all pretimeout code The time from enabling watchdog to WS0 is the same with the time from WS0 to WS1, they are both timeout value. 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.

[PATCH 00/11] Add self-probe infrastructure and stacked irqdomain support for ACPI based GICv2/3 init

by Hanjun Guo

This patch set introduce self-probe infrastructure to init IRQ controllers and stacked irqdomain support for ACPI based GICv2/3 init. The self-probe infrastructure for ACPI GIC init is similar as IRQCHIP_DECLARE() and based on the GIC version support in ACPI MADT table. We introduce acpi_irq_domain for GICv2/3 core domain to support stacked irqdomain, and pass the gsi (global system interrupt) as the agument (void *arg) for gic_irq_domain_alloc(), then we can alloc virqs via acpi_register_gsi() with stacked irqdomain. In order to make ACPI related GIC init code slef-contained, I consolidated all the GIC init code into drivers/irqchip/irq-gic-acpi.c. update from RFC version: - Consolidate all the GIC init code into drivers/irqchip/irq-gic-acpi.c Hanjun Guo (8): irqchip / GIC: Add GIC version support in ACPI MADT irqchip / GIC / ACPI: Use IRQCHIP_ACPI_DECLARE to simplify GICv2 init code irqchip / gic: Add stacked irqdomain support for ACPI based GICv2 init ACPI / gsi: Add gsi_mutex to synchronize acpi_register_gsi()/acpi_unregister_gsi() irqchip / GICv3: Add ACPI support for GICv3+ initialization irqchip / GICv3: Add stacked irqdomain support for ACPI based init irqchip / GICv2 / ACPI: Consolidate GICv2 ACPI related init code irqchip / GICv3 / ACPI: Consolidate GICv3 ACPI related init code Tomasz Nowicki (3): ACPICA: Introduce GIC version for arm based system ACPI / irqchip: Add self-probe infrastructure to initialize IRQ controller irqchip / GICv3: Refactor gic_of_init() for GICv3 driver arch/arm64/Kconfig | 1 + arch/arm64/include/asm/irq.h | 13 -- arch/arm64/kernel/acpi.c | 25 --- drivers/acpi/Makefile | 1 + drivers/acpi/gsi.c | 41 +++-- drivers/acpi/irq.c | 40 +++++ drivers/irqchip/Kconfig | 3 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-gic-acpi.c | 318 +++++++++++++++++++++++++++++++++++ drivers/irqchip/irq-gic-v3.c | 149 +++++++++------- drivers/irqchip/irq-gic.c | 129 ++------------ drivers/irqchip/irqchip.h | 12 ++ include/acpi/actbl1.h | 17 +- include/asm-generic/vmlinux.lds.h | 13 ++ include/linux/acpi.h | 14 ++ include/linux/acpi_irq.h | 4 +- include/linux/irqchip/arm-gic-acpi.h | 13 +- include/linux/irqchip/arm-gic-v3.h | 10 ++ include/linux/mod_devicetable.h | 7 + 19 files changed, 577 insertions(+), 234 deletions(-) create mode 100644 drivers/acpi/irq.c create mode 100644 drivers/irqchip/irq-gic-acpi.c -- 1.9.1

ARM Juno Board + UEFI/ACPI + Linux + USB

by Bush, Jeff (System Firmware)

I am experimenting with the ARM Juno board + UEFI/ACPI + Linux + USB but I have found that Linux fails to initialize the USB host. The UEFI/ACPI firmware is built using version 3.1 of https://github.com/ARM-software/edk2 The Linux image is built using the leg-20150609.0 tag of https://git.linaro.org/leg/acpi/leg-kernel.git Because I only want ACPI tables and no FDT blob I removed the FdtPlatformDxe driver from ArmJuno.fdf when I build the UEFI/ACPI firmware image. When I boot Linux from the UEFI shell using the following command line: FS2:\> Image acpi=force initrd=rootfs-aarch64.cpio root=/dev/ram0 rw ignore_loglevel console=ttyAMA0,115200n8 earlyprintk=pl011,0x7ff80000 verbose debug I am able to boot to the Linux command line but the USB host fails to initialize and the following output is displayed to the console during boot: [ 7.463340] ehci-platform ARMH0D20:00: fatal error [ 7.468144] ehci-platform ARMH0D20:00: HC died; cleaning up [ 7.483700] random: nonblocking pool is initialized [ 7.600738] irq 149: nobody cared (try booting with the "irqpoll" option) [ 7.607539] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.1.0-rc6+ #1 [ 7.613814] Hardware name: (null) (DT) [ 7.617564] Call trace: [ 7.620024] [<fffffe000008a85c>] dump_backtrace+0x0/0x138 [ 7.625433] [<fffffe000008a9b0>] show_stack+0x1c/0x28 [ 7.630494] [<fffffe00007b1650>] dump_stack+0x84/0xc8 [ 7.635556] [<fffffe00000ece60>] __report_bad_irq+0x44/0xf4 [ 7.641138] [<fffffe00000ed3b0>] note_interrupt+0x208/0x2c0 [ 7.646720] [<fffffe00000eaa04>] handle_irq_event_percpu+0x1b4/0x230 [ 7.653084] [<fffffe00000eaad0>] handle_irq_event+0x50/0x80 [ 7.658666] [<fffffe00000edb34>] handle_fasteoi_irq+0xb0/0x178 [ 7.664508] [<fffffe00000e9e20>] generic_handle_irq+0x38/0x54 [ 7.670263] [<fffffe00000ea170>] __handle_domain_irq+0x68/0xbc [ 7.676105] [<fffffe0000082474>] gic_handle_irq+0x38/0x88 [ 7.681511] Exception stack(0xfffffe0000b03b80 to 0xfffffe0000b03ca0) [ 7.687966] 3b80: 00ae3000 fffffe00 00000000 00000000 00b03cc0 fffffe00 0009fa68 fffffe00 [ 7.696161] 3ba0: 00000000 00000000 00c00d00 fffffe00 00c00d00 fffffe00 ffff8d9e 00000000 [ 7.704356] 3bc0: 9b967b22 00000000 275ee5db 00000000 00ae3ee0 fffffe00 7f320000 00000009 [ 7.712550] 3be0: 1ef8f97d 00000000 00000000 00000000 00c03000 fffffe00 00b41000 fffffe00 [ 7.720744] 3c00: 00000006 00000000 00000018 00000000 fffffffe 0fffffff b2c50ac8 000003ff [ 7.728939] 3c20: 0009f064 fffffe00 004e9d58 00000000 df62e520 000003ff 00ae3000 fffffe00 [ 7.737133] 3c40: 00000000 00000000 00000000 00000000 740c1000 fffffe09 60000145 00000000 [ 7.745327] 3c60: 00b00000 fffffe00 00000040 00000000 00ad0b00 fffffe00 00b30000 fffffe00 [ 7.753522] 3c80: 007c59c8 fffffe00 00b03cc0 fffffe00 0009f9dc fffffe00 00b03cc0 fffffe00 [ 7.761714] [<fffffe00000855a4>] el1_irq+0x64/0xd8 [ 7.766514] [<fffffe000009ff54>] irq_exit+0x98/0xd8 [ 7.771399] [<fffffe00000ea174>] __handle_domain_irq+0x6c/0xbc [ 7.777240] [<fffffe0000082474>] gic_handle_irq+0x38/0x88 [ 7.782645] Exception stack(0xfffffe0000b03dc0 to 0xfffffe0000b03ee0) [ 7.789100] 3dc0: 00b00000 fffffe00 00000000 00000000 00b03f00 fffffe00 00086bc4 fffffe00 [ 7.797294] 3de0: 000db56c fffffe00 00000000 00000000 00000001 00000000 00b33000 fffffe00 [ 7.805488] 3e00: 00000000 00000000 0ccccccd 00000000 80000000 00232aaf 00000000 00000000 [ 7.813682] 3e20: 00c16938 fffffe00 00000000 00000000 00000020 00000000 00000040 00000000 [ 7.821876] 3e40: 00000030 00000000 ffffffff ffffffff ffffffff ffffffff b2c50ac8 000003ff [ 7.830071] 3e60: 0009f064 fffffe00 004e9d58 00000000 df62e520 000003ff 00b00000 fffffe00 [ 7.838265] 3e80: 00000000 00000000 00b30000 fffffe00 00000000 00000000 00bd0000 fffffe00 [ 7.846460] 3ea0: 00b30640 fffffe00 00b03f10 fffffe00 00ad0b00 fffffe00 00ae5058 fffffe00 [ 7.854654] 3ec0: 007c59c8 fffffe00 00b03f00 fffffe00 00086bc0 fffffe00 00b03f00 fffffe00 [ 7.862847] [<fffffe00000855a4>] el1_irq+0x64/0xd8 [ 7.867647] [<fffffe00000db568>] cpu_startup_entry+0x324/0x374 [ 7.873494] [<fffffe00007ab30c>] rest_init+0x88/0x94 [ 7.878467] [<fffffe0000a309ac>] start_kernel+0x3d8/0x3f0 [ 7.883870] handlers: [ 7.886145] [<fffffe00006092ec>] usb_hcd_irq [ 7.890422] Disabling IRQ #149 If I boot Linux using the same command line as above but replace 'acpi=force' with 'dtb=juno.dtb' the error does not occur, the USB host is initialized and a USB flash drive is discovered. Is this a known issue? This error could occur because the ACPI tables do not have the right information or because the kernel is not getting the right information from the tables. Do ya'll have any ideas on what might be wrong and where I should look in the code to fix this problem? Thank you for your help Jeff Bush

[V6 PATCH 0/7] ACPI: Introduce support for _CCA object

by Suravee Suthikulpanit

This patch series introduce support for _CCA object, which is currently used mainly by ARM64 platform to specify DMA coherency attribute for devices when booting with ACPI. A copy of ACPIv6 can be found here: http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf This patch also introduces a new APIS: 1. acpi_check_dma() as part of ACPI API. 2. device_dma_is_coherent() as part of unified device property API. This simplifies the logic in device drivers to determine device coherency attribute regardless of booting with DT vs ACPI. This has been tested on AMD-Seattle platform, which implements _CCA object as described in the AMD Opteron A1100 Series Processor ACPI Porting Guide: http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2012/10/Seattle_ACPI… Changes from V5 (https://lkml.org/lkml/2015/5/20/1033): * Fix build error in the megaraid and ufs driver (reported by Mark Salter) Changes from V4 (https://lkml.org/lkml/2015/5/15/669): * Patch1: - Move the arch_setup_dma_ops() call from acpi_create_platform_device() to acpi_bind_one() to support other bus types (per Rafael). - Rename acpi_device_flags.is_coherent to acpi_device_flags.coherent_dma. (per Rafael) - Refactor acpi_dma_is_supported() and acpi_dma_is_coherent() to acpi_check_dma() to simplify the new interface. - Only support _CCA=1 for now. See acpi_check_dma() (per Arnd and Catalin) * Patch2: - Add acked-by Catalin. * Patch3: - Use ACPI_COMPANION() instead of acpi_node(). - Remove has_acpi_companion() check since already done by acpi_node(). (per Will) * Remove the patch "Generic function for setting up PCI device DMA coherency" introduced in V4. (per Bjorn) Changes from V3 (https://lkml.org/lkml/2015/5/7/1004): * Remove ARCH64_SUPPORT_ACPI_CCA_ZERO and just use CONFIG_ARM64. (per Catalin and Rafael) * Do not need to call arch_setup_dma_ops() for acpi_device->dev. (per Rafael) * [3/6] (New) We also need to call arch_setup_dma_ops() for pci devices and check the CCA of the host bridge. Similar logic exists for OF. So, I refactor of_pci_dma_configure() to the more generic version pci_dma_configure(), and add support for ACPI. Changes from V2 (https://lkml.org/lkml/2015/5/5/510): * Reword ACPI_MUST_HAVE_CCA to ACPI_CCA_REQUIRED (per Rafael) * Reword ACPI_SUPPORT_CCA_ZERO to ARCH64_SUPPORT_ACPI_CCA_ZERO (per Rafael and Arnd) * Misc code styling clean up (per Rafael) * Only print missing _CCA warning message in debug mode. * Refactor logic in acpi_setup_device_dma() into if acpi_dma_is_supported() then call arch_setup_dma_ops(). * Do not allocate device dma_mask if !acpi_dma_is_supported() (per Arnd). * Re-use the dummy functions with the same signature. Changes from V1 (https://lkml.org/lkml/2015/4/29/290): * Remove supports for 32-bit ARM since doesn't currently supporting ACPI (Per Catalin suggestions.) * Do not call arch_setup_dma_ops() and when _CCA is missing. (per Arnd suggestion) * Add CONFIG_ACPI_SUPPORT_CCA_ZERO kernel config flag to allow architectures to specify the behavior when _CCA=0. * Add dummy_dma_ops for ARM64 (per Catalin suggestions). * Fixed build error when ACPI is not configured by defining acpi_dma_is_coherent() for when CONFIG_ACPI is not set. * Introduce device_dma_is_coherent(). * Use device_dma_is_coherent in crypto/ccp and amd-xgbe driver. Changes from RFC: (https://lkml.org/lkml/2015/4/1/389) * New logic for deriving and propagating coherent attribute from parent devices. (by Mark) * Introducing acpi_dma_is_coherent() API (Per Tom suggestion) * Introducing CONFIG_ACPI_MUST_HAVE_CCA kernel configuration. * Rebased to linux-4.1-rc1 Suravee Suthikulpanit (7): ACPI / scan: Parse _CCA and setup device coherency arm64 : Introduce support for ACPI _CCA object device property: Introduces device_dma_is_coherent() crypto: ccp - Unify coherency checking logic with device_dma_is_coherent() amd-xgbe: Unify coherency checking logic with device_dma_is_coherent() megaraid_sas: fix TRUE and FALSE re-define build error ufs: fix TRUE and FALSE re-define build error arch/arm64/Kconfig | 1 + arch/arm64/include/asm/dma-mapping.h | 18 +++++- arch/arm64/mm/dma-mapping.c | 92 +++++++++++++++++++++++++++++++ drivers/acpi/Kconfig | 3 + drivers/acpi/acpi_platform.c | 2 +- drivers/acpi/glue.c | 5 ++ drivers/acpi/scan.c | 35 ++++++++++++ drivers/base/property.c | 14 +++++ drivers/crypto/ccp/ccp-platform.c | 60 +------------------- drivers/net/ethernet/amd/xgbe/xgbe-main.c | 27 +-------- drivers/scsi/megaraid/megaraid_sas_fp.c | 8 +++ drivers/scsi/ufs/unipro.h | 8 +++ include/acpi/acpi_bus.h | 37 ++++++++++++- include/linux/acpi.h | 5 ++ include/linux/property.h | 2 + 15 files changed, 228 insertions(+), 89 deletions(-) -- 2.1.0
