[V7 PATCH 0/3] Introduce ACPI support for ahci_platform driver

by Suravee Suthikulpanit

This patch series introduce ACPI support for AHCI platform driver. Existing ACPI support for AHCI assumes the device controller is a PCI device. Since there is no ACPI _CID for generic AHCI controller, the driver could not use it for matching devices. Therefore, this patch introduces a mechanism for drivers to match devices using ACPI _CLS method. _CLS contains PCI-defined class-code. This patch series also modifies ACPI modalias to add class-code to the exisiting format, which currently only uses _HID and _CIDs. This is required to support loadable modules w/ _CLS. This is rebased from and tested with: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v11 This topic was discussed earlier here (as part of introducing support for AMD Seattle SATA controller): http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2 Changes from V6 (https://lkml.org/lkml/2015/3/25/797) * Adding Acked-by Mika, and Reviewed-by Hanjun * Minor clen up to use lower case 0xffffff for cls_msk (per Mika suggestions). * Modify the ACPI_DEVICE_CLASS macro to use designated initializer (per Mika suggestions). Changes from V5 (https://lkml.org/lkml/2015/3/6/24) * Rebased and tested with acpi-5.1-v11 * Splitting up the ACPICA changes into a separate patch [1/3]. (per Mika suggestion) * Adding class-code mask support (per Mika suggestion) * Use macro to define struct acpi_device_id entry (per Mika suggestion) * Note: Mika also recommend reordering the member of struct acpi_device_id and define a macro to be used for declaring each table entry. This is a large amount of changes, and will be done separtely from this patch series. Changes from V4 (https://lkml.org/lkml/2015/3/2/56) * [1/2] Bug fixed: Reorder the declaration of struct acpi_pnp_device_id cls in the struct acpi_device_info (include/acpi/actypes.h) since compatible_id_list must be last one. * [2/2] Added Acked-by: Tejun Heo <tj(a)kernel.org> Changes from V3 (https://lkml.org/lkml/2015/2/8/106) * Instead of introducing new structure acpi_device_cls, add cls into the acpi_device_id, and modify the __acpi_match_device to also match for cls. (per Mika suggestion.) * Add loadable module support, which requires changes in ACPI modalias. (per Mika suggestion.) * Rebased and tested with acpi-5.1-v9 Changes from V2 (https://lkml.org/lkml/2015/1/5/662) * Update with review comment from Rafael in patch 1/2 * Rebased and tested with acpi-5.1-v8 Changes from V1 (https://lkml.org/lkml/2014/12/19/345) * Rebased to 3.19.0-rc2 * Change from acpi_cls in device_driver to acpi_match_cls (Hanjun comment) * Change the matching logic in acpi_driver_match_device() due to the new special PRP0001 _HID. * Simplify the return type of acpi_match_device_cls() to boolean. Changes from RFC (https://lkml.org/lkml/2014/12/17/446) * Remove #ifdef and make non-ACPI version of the acpi_match_device_cls as inline.

[PATCH 0/7] minor cleanups for ACPI processor driver

by Hanjun Guo

This patch set are some minor cleanups for ACPI processor driver to address the comments which raised by Rafael in ARM64 ACPI core patches, so this patch set is on top of ARM64 ACPI core patches the git tree is git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git branch for-next/acpi. Rafael, I assume this patchset will be taken with your tree if it makes sense, any rebase work needed please let me know. the last patch - ACPI / processor: Introduce invalid_phys_cpuid() will cut u64 mpidr to int, but I think it is ok for error values, correct me if I'm wrong. Comments are welcomed. Hanjun Guo (7): ACPI / processor: remove cpu_index in acpi_processor_get_info() ACPI / processor: remove phys_id in acpi_processor_get_info() ACPI / processor: Introduce invalid_logical_cpuid() Xen / ACPI / processor: use invalid_logical_cpuid() Xen / ACPI / processor: Remove unneeded NULL check in xen_acpi_processor_enable() ACPI / processor: return specific error instead of -1 ACPI / processor: Introduce invalid_phys_cpuid() drivers/acpi/acpi_processor.c | 20 +++++++++----------- drivers/acpi/processor_core.c | 10 +++++----- drivers/acpi/processor_pdc.c | 5 +---- drivers/xen/xen-acpi-cpuhotplug.c | 12 +++--------- include/linux/acpi.h | 10 ++++++++++ 5 files changed, 28 insertions(+), 29 deletions(-) -- 1.9.1

[update][PATCH v10 06/21] ACPI / sleep: Introduce CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT

From: Graeme Gregory <graeme.gregory(a)linaro.org> ACPI 5.1 does not currently support S states for ARM64 hardware but ACPI code will call acpi_target_system_state() and acpi_sleep_init() for device power management, so introduce CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT and select it for x86 and ia64 only to make sleep functions available, and also introduce stub function to allow other drivers to function until S states are defined for ARM64.

leg-kernel tag leg-20150318.0 released

by Graeme Gregory

The leg-kernel release has been made and tagged as leg-20150318.0 This is based on mainline kernel v4.0-rc4 Repository : http://git.linaro.org/leg/acpi/leg-kernel.git Direct Link: https://git.linaro.org/leg/acpi/leg-kernel.git/commit/9c397babcfc590123c904… Notes :- 1) This release restores support for AMD Seattle. 2) This release incorporates the SBSA UART support for pl011 driver from Andre Przywara. This means that your console will become ttyAMA0 (console=ttyAMA0) on Juno/FVP. It also means to run FVP model you need these options :- -C bp.pl011_uart0.untimed_fifos=0 -C bp.pl011_uart0.revision="r1p5"

[update][PATCH v10 13/21] ACPI / processor: Introduce phys_cpuid_t for CPU hardware ID

by Hanjun Guo

CPU hardware ID (phys_id) is defined as u32 in structure acpi_processor, but phys_id is used as int in acpi processor driver, so it will lead to some inconsistence for the drivers. Furthermore, to cater for ACPI arch ports that implement 64 bits CPU ids a generic CPU physical id type is required. So introduce typedef u32 phys_cpuid_t in a common file, and introduce a macro PHYS_CPUID_INVALID as (phys_cpuid_t)(-1) if it's not defined by other archs, this will solve the inconsistence in acpi processor driver, and will prepare for the ACPI on ARM64 for the 64 bit CPU hardware ID in the following patch.

This patch set is going to isolate non-architecure specific code and make it accessible for all architectures. v1 -> v2 changes: - use generic readb/readw etc. accessors instead of AMD Fam10h workaround - separate ACPI and ECAM code - improve ECAM code naming Tomasz Nowicki (9): x86, pci: Clean up comment about buggy MMIO config space access for AMD Fam10h CPUs. x86, pci: Abstract PCI config accessors and use AMD Fam10h workaround exclusively. 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. pci, acpi, mcfg: Share ACPI PCI config space accessors. pci, ecam: Improve naming for ecam.c content and areas where it is used. arch/x86/Kconfig | 3 + arch/x86/include/asm/pci_x86.h | 34 +--- arch/x86/pci/Makefile | 5 +- arch/x86/pci/acpi.c | 3 +- arch/x86/pci/mmconfig-shared.c | 340 +++++++++++---------------------------- arch/x86/pci/mmconfig_32.c | 47 ++---- arch/x86/pci/mmconfig_64.c | 153 ------------------ arch/x86/pci/numachip.c | 27 +--- drivers/acpi/Makefile | 1 + drivers/acpi/mcfg.c | 121 ++++++++++++++ drivers/pci/Kconfig | 7 + drivers/pci/Makefile | 5 + drivers/pci/ecam.c | 356 +++++++++++++++++++++++++++++++++++++++++ drivers/xen/pci.c | 6 +- include/linux/ecam.h | 56 +++++++ 15 files changed, 668 insertions(+), 496 deletions(-) delete mode 100644 arch/x86/pci/mmconfig_64.c create mode 100644 drivers/acpi/mcfg.c create mode 100644 drivers/pci/ecam.c create mode 100644 include/linux/ecam.h -- 1.9.1

[RFC PATCH 0/7] hw/arm/virt: Dynamic ACPI v5.1 table generation

by Alexander Spyridakis

Currently, the virt machine model generates Device Tree information dynamically based on the existing devices in the system. This patch series extends the same concept but for ACPI information instead. A total of seven tables have been implemented in this patch series, which is the minimum for a basic ARM support. The set of generated tables are: - RSDP - XSDT - MADT - GTDT - FADT - FACS - DSDT The tables are created in standalone buffers, taking into account the needed information passed from the virt machine model. When the generation is finalized, the individual buffers are compacted to a single ACPI binary blob, where it is injected on the guest memory space in a fixed location. The guest kernel can find the ACPI tables by providing to it the physical address of the ACPI blob (e.g. acpi_rsdp=0x47000000 boot argument). This series has been tested on the Foundation Model 0.8 build 5206 and the Juno development board. For kernel and driver support it is based on the "Introduce ACPI for ARM64 based on ACPI 5.1" and "Drivers for Juno to boot from ACPI" patch series from Hanjun Guo.

[V4 PATCH 0/2] Introduce ACPI support for ahci_platform driver

by Suravee Suthikulpanit

This patch series introduce ACPI support for AHCI platform driver. Existing ACPI support for AHCI assumes the device controller is a PCI device. Since there is no ACPI _CID for generic AHCI controller, the driver could not use it for matching devices. Therefore, this patch introduces a mechanism for drivers to match devices using ACPI _CLS method. _CLS contains PCI-defined class-code. This patch series also modifies ACPI modalias to add class-code to the exisiting format, which currently only uses _HID and _CIDs. This is required to support loadable modules w/ _CLS. This patch series is rebased from and tested with: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v9 This topic was discussed earlier here (as part of introducing support for AMD Seattle SATA controller): http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2 Changes from V3 (https://lkml.org/lkml/2015/2/8/106) * Instead of introducing new structure acpi_device_cls, add cls into the acpi_device_id, and modify the __acpi_match_device to also match for cls. (per Mika suggestion.) * Add loadable module support, which requires changes in ACPI modalias. (per Mika suggestion.) * Rebased and tested with acpi-5.1-v9 Changes from V2 (https://lkml.org/lkml/2015/1/5/662) * Update with review comment from Rafael in patch 1/2 * Rebased and tested with acpi-5.1-v8 Changes from V1 (https://lkml.org/lkml/2014/12/19/345) * Rebased to 3.19.0-rc2 * Change from acpi_cls in device_driver to acpi_match_cls (Hanjun comment) * Change the matching logic in acpi_driver_match_device() due to the new special PRP0001 _HID. * Simplify the return type of acpi_match_device_cls() to boolean. Changes from RFC (https://lkml.org/lkml/2014/12/17/446) * Remove #ifdef and make non-ACPI version of the acpi_match_device_cls as inline. (per Arnd) * Simplify logic to retrieve and evaluate _CLS handle.

[PATCH v3 0/9] Start deprecating _OSI on new architectures

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> The use of the ACPI _OSI method in Linux has a long and sordid history. Instead of perpetuating past complications on new architectures, the consensus amongst those writing the ACPI specification and those using it seems to be to ultimately deprecate the use of _OSI. A change request has been submitted (but not yet decided upon) to modify the ACPI spec accordingly. In the meantime, these patches rearrange the implementation of _OSI so that it can be deprecated, or ultimately removed completely, on at least arm64 platforms. This is done by separating out the _OSI implementation and moving it into a new file. For x86 and ia64, there is no change in functionality. But, this allows us to provide a separate implementation of _OSI for arm64 that generates a warning that it has been deprecated, and always returns false; i.e., that the capability being queried for, whether OS name or functionality, is not supported. Patches 0005 through 0008 provide these changes; the first four patches are solely cleanup to the file drivers/acpi/osl.c made so that checkpatch will not complain. The final patch changes the default value for the _OS_ method for arm64 only. Since there is no need to pretend to be older versions of Windows, or any other OS at all, the _OS_ method will return "Linux" on arm64. One can still use the acpi_os_name kernel parameter if there is a need to use some other value. The first seven patches do not depend on arm64 support for ACPI and could be used independently. The last two patches make much more sense when used in conjunction with Hanjun's patches for ACPI 5.1 on arm64 [0]. In fact, patch 0008 cannot be applied without [0]. These have been through some simple testing on two different x86 laptops, and all seems well (Lenovo t440s and t430s ThinkPads). The arm64 code has been tested on an AMD Seattle system. Unfortunately, for ia64, all I could do was cross-compile the code; I have no access to hardware to test on. NB: the first four patches are solely cleanup to drivers/acpi/osl.c based on the results from checkpatch and can be treated independently. However, the remainder of the patch set assumes this cleanup has been done. There are some checkpatch warnings still remaining in osl.c -- specifically about use of volatiles and one line of 81 characters -- that these patches intentionally do not correct as they do not appear to need correcting. Changes in v3: -- add in cleanup to osl.c based on checkpatch output -- put arch-specific _OSI implementation in the correct place (arch/*) -- modify CONFIG item names and make them so they are not user selectable -- get rid of the BLACKLIST config item; it wasn't really needed. Changes in v2: -- significant simplification based on Rafael's comments -- ACPI spec change request has now been submitted [0] https://lkml.org/lkml/2015/2/2/261 Al Stone (9): ACPI: fix all errors reported by cleanpatch.pl in osl.c ACPI: clear up warnings on use of printk reported by checkpatch.pl ACPI: clean up checkpatch warnings for various bits of syntax ACPI: clean up checkpatch warnings for items with possible semantic value ACPI: move acpi_os_handler() so it can be made arch-dependent later ACPI: move _OSI support functions to allow arch-dependent implementation ACPI: enable arch-specific compilation for _OSI and the blacklist ACPI: arm64: use an arch-specific ACPI _OSI method and ACPI blacklist ACPI: arm64: use "Linux" as ACPI_OS_NAME for _OS on arm64 arch/arm64/Kconfig | 6 + arch/arm64/kernel/Makefile | 2 +- arch/arm64/kernel/acpi-blacklist.c | 20 ++ arch/arm64/kernel/acpi-osi.c | 25 +++ drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 5 + drivers/acpi/osi.c | 245 +++++++++++++++++++++++ drivers/acpi/osl.c | 387 ++++++++----------------------------- include/acpi/acconfig.h | 2 + include/acpi/platform/aclinux.h | 4 + include/linux/acpi.h | 14 +- 11 files changed, 406 insertions(+), 307 deletions(-) create mode 100644 arch/arm64/kernel/acpi-blacklist.c create mode 100644 arch/arm64/kernel/acpi-osi.c create mode 100644 drivers/acpi/osi.c -- 2.1.0

[PATCH v8 00/21] Introduce ACPI for ARM64 based on ACPI 5.1

by Hanjun Guo

Hi, This is the v8 of ACPI core patches for ARM64 based on ACPI 5.1, there are some updates since v7: - Add two more documantation to explain why we need ACPI in ARM64 servers by Grant, and recommendations and prohibitions on the use of the numerous ACPI tables and objects by Al Stone. - Add two patches which is need to map acpi tables after acpi_gbl_permanent_mmap is set - Add another patch "dt / chosen: Add linux,uefi-stub-generated-dtb property" to address that if firmware providing no dtb, we can try ACPI configuration data even if no "acpi=force" is passed in early parameters. (I think ACPI for XEN and kexec need consider sperately as disscussed, correct me if I'm wrong). - Add CC in the patch to the subsystem maintainers and modify the subject of the patch to explicitly show the subsystem touched by this patch set, please help us to review and ack them if they make sense, thanks. - Add Tested-by from Qualcomm and Redhat; - Make ACPI depends on PCI suggested by Catalin; - Clean up SMP init function as Lorenzo suggested, remove physical CPU hot-plug code in the patch; - Address some comments from Marc and explicitly state that will implment statcked irqdomain and GIC init framework when GICv3 and ITS, GICv2m are implemented; - Rebased on top of 3.19-rc7. previous version is here: v7: https://lkml.org/lkml/2015/1/14/586 v6: https://lkml.org/lkml/2015/1/4/40 Any comments are welcome :) Thanks Hanjun Al Stone (4): ARM64 / ACPI: Get RSDP and ACPI boot-time tables ARM64 / ACPI: Introduce early_param for "acpi" and pass acpi=force to enable ACPI ARM64 / ACPI: Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64 arm64: ACPI: additions of ACPI documentation for arm64 Graeme Gregory (6): acpi: add arm64 to the platforms that use ioremap ACPI / sleep: Introduce sleep_arm.c ARM64 / ACPI: If we chose to boot from acpi then disable FDT ARM64 / ACPI: Get PSCI flags in FADT for PSCI init ARM64 / ACPI: Enable ARM64 in Kconfig Documentation: ACPI for ARM64 Hanjun Guo (8): ARM64 / ACPI: Introduce PCI stub functions for ACPI dt / chosen: Add linux,uefi-stub-generated-dtb property ARM64 / ACPI: Disable ACPI if FADT revision is less than 5.1 ACPI / table: Print GIC information when MADT is parsed ARM64 / ACPI: Parse MADT for SMP initialization ACPI / processor: Make it possible to get CPU hardware ID via GICC ARM64 / ACPI: Introduce ACPI_IRQ_MODEL_GIC and register device's gsi clocksource / arch_timer: Parse GTDT to initialize arch timer Mark Salter (2): acpi: fix acpi_os_ioremap for arm64 arm64: allow late use of early_ioremap Tomasz Nowicki (1): irqchip: Add GICv2 specific ACPI boot support Documentation/arm/uefi.txt | 3 + Documentation/arm64/acpi_object_usage.txt | 592 ++++++++++++++++++++++++++++++ Documentation/arm64/arm-acpi.txt | 506 +++++++++++++++++++++++++ Documentation/arm64/why_use_acpi.txt | 231 ++++++++++++ Documentation/kernel-parameters.txt | 3 +- arch/arm64/Kconfig | 3 + arch/arm64/include/asm/acenv.h | 18 + arch/arm64/include/asm/acpi.h | 103 ++++++ arch/arm64/include/asm/cpu_ops.h | 1 + arch/arm64/include/asm/fixmap.h | 3 + arch/arm64/include/asm/pci.h | 6 + arch/arm64/include/asm/psci.h | 3 +- arch/arm64/include/asm/smp.h | 5 +- arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/acpi.c | 362 ++++++++++++++++++ arch/arm64/kernel/cpu_ops.c | 2 +- arch/arm64/kernel/pci.c | 25 ++ arch/arm64/kernel/psci.c | 78 ++-- arch/arm64/kernel/setup.c | 58 ++- arch/arm64/kernel/smp.c | 2 +- arch/arm64/kernel/time.c | 7 + drivers/acpi/Kconfig | 3 +- drivers/acpi/Makefile | 4 + drivers/acpi/bus.c | 3 + drivers/acpi/osl.c | 6 +- drivers/acpi/processor_core.c | 37 ++ drivers/acpi/sleep_arm.c | 28 ++ drivers/acpi/tables.c | 43 +++ drivers/clocksource/arm_arch_timer.c | 132 +++++-- drivers/firmware/efi/libstub/fdt.c | 8 + drivers/irqchip/irq-gic.c | 102 +++++ drivers/irqchip/irqchip.c | 3 + include/acpi/acpi_io.h | 6 + include/linux/acpi.h | 16 + include/linux/clocksource.h | 6 + include/linux/irqchip/arm-gic-acpi.h | 31 ++ 36 files changed, 2374 insertions(+), 66 deletions(-) create mode 100644 Documentation/arm64/acpi_object_usage.txt create mode 100644 Documentation/arm64/arm-acpi.txt create mode 100644 Documentation/arm64/why_use_acpi.txt create mode 100644 arch/arm64/include/asm/acenv.h create mode 100644 arch/arm64/include/asm/acpi.h create mode 100644 arch/arm64/kernel/acpi.c create mode 100644 drivers/acpi/sleep_arm.c create mode 100644 include/linux/irqchip/arm-gic-acpi.h -- 1.9.1

[PATCH 0/6] PCI: MMCONFIG clean up

by Tomasz Nowicki

MMCFG ACPI table has no arch dependencies so it can be used across all architectures. Currently MMCONFIG related code resides in arch/x86 directories. This patch set is goint to isolate non-architecure specific code and make it accessible from drivers/pci/ directory. Tomasz Nowicki (6): x86, acpi, pci: Reorder logic of pci_mmconfig_insert() function x86, acpi, pci: Move arch-agnostic MMCFG code out of arch/x86/ directory x86, acpi, pci: Move PCI config space accessors. x86, acpi, pci: mmconfig_{32,64}.c code refactoring - remove code duplication. x86, acpi, pci: mmconfig_64.c becomes default implementation for arch agnostic low-level direct PCI config space accessors via MMCONFIG. pci, acpi: Share ACPI PCI config space accessors. arch/x86/include/asm/pci.h | 42 +++++ arch/x86/include/asm/pci_x86.h | 72 -------- arch/x86/pci/Makefile | 5 +- arch/x86/pci/acpi.c | 1 + arch/x86/pci/init.c | 1 + arch/x86/pci/mmconfig-shared.c | 242 ++++--------------------- arch/x86/pci/mmconfig_32.c | 11 +- arch/x86/pci/mmconfig_64.c | 153 ---------------- drivers/acpi/Makefile | 1 + drivers/acpi/bus.c | 1 + drivers/acpi/mmconfig.c | 396 +++++++++++++++++++++++++++++++++++++++++ include/linux/mmconfig.h | 62 +++++++ include/linux/pci.h | 8 - 13 files changed, 541 insertions(+), 454 deletions(-) delete mode 100644 arch/x86/pci/mmconfig_64.c create mode 100644 drivers/acpi/mmconfig.c create mode 100644 include/linux/mmconfig.h -- 1.9.1
