Values set within all APEI tables have no hardware meaning and are valid combining with kernel hacks. These changes allow only to confirm that APEI tables (HEST, ERST, BERT) are supported by kernel and no issues were observed on arm/arm64 architectures.

[PATCH 0/6 v2] First of the Arndale GPIO/pinctrl patches

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> I should have sent these out for comment much sooner. Once these are in good shape, the next steps are to send patches for verifying that the pinconf code is working properly, connecting up the GPIO interrupts using ACPI, and then conversion of all of the pin controllers for Arndale (this patch converts one of four). This patch puts most of the infrastructure in place so that in the 3.11 kernel the Arndale pin controllers can be converted from FDT to ACPI. The changes in ASL are included in a separate patch. What this allows is for the pin controllers to be described in either FDT or ACPI for Arndale and -- in conjunction with the ASL changes -- shows how to describe a Samsung controller in ACPI. Changes for v2: -- Add patch 6 which allows compilation regardless of whether CONFIG_ACPI is used or not Al Stone (6): ACPI: ARM: arndale: remove GPZ GPIO definition from DT so it can be in ACPI ACPI: ARM: arndale: whitelist the samsung-pinctrl driver for ACPI ACPI: make an error message a little clearer ACPI: improve acpi_extract_package() utility ACPI: ARM: arndale: enable ACPI in the Samsung pinctrl driver ACPI: ARM: arndale: add CONFIG_ACPI ifdef's to pinctrl driver arch/arm/boot/dts/exynos5250-pinctrl.dtsi | 2 + arch/arm/boot/dts/exynos5250.dtsi | 6 +- drivers/acpi/acpi_platform.c | 3 + drivers/acpi/osl.c | 2 +- drivers/acpi/utils.c | 17 +- drivers/pinctrl/pinctrl-samsung.c | 517 +++++++++++++++++++++++++++++- drivers/pinctrl/pinctrl-samsung.h | 3 + 7 files changed, 536 insertions(+), 14 deletions(-) -- 1.8.3.1

[PATCH v2] ASL / ARMv8 foudation model: Fix cpu hot add failure on ARM64

by Hanjun Guo

All values in the ACPI blob are little-endian, but I creat the DSDT table with values in big-endian format, so when I evaluate _MAT object I will get values unexperted, this leads to cpu hot add failure, fix it. v1 -> v2: No functional change, just change the title for better readability.

[PATCH part1 00/10] ARM64 / ACPI: CPU hotplug support

by Hanjun Guo

This patch set is the kernel part of code for cpu hotplug. I got a patch in upstream but not accepted by mainline, this patch emulate an ACPI SCI interrupt to emulate a hot-plug event. Useful for testing ACPI based hot-plug on systems that don't have the necessary firmware support. With this patch, I can test the hot-add and hot-remove repeatly. This patch set is intended to close the cpu hotplug related cards in JIRA, just for review purpose, *should not* pushed to our linaro acpi. I have created an acpi-hotplug-next branch in our git tree for these patches. This patch set includes 3 parts, the forst part is the kernel code, and the second is the ASL code fix, the third part is the boot wrapper.

by al.stone＠linaro.org

From: Al Stone <ahs3(a)redhat.com> The first two patches in this series have been submitted before; this series just combines all of the Arndale GPIO changes so far. The last of the three converts yet another GPIO device to ACPI. All that remains is to convert the final controller.

CSRT table can be used to describe DMA on SoC

by Hanjun Guo

Hi everyone, I read the wiki about ACPI Table Prioritization: https://wiki.linaro.org/LEG/Engineering/Kernel/ACPI/TablePriorities and I noticed that CSRT is in the *Never Tables* priority, here I got some different opinions. Yes, CSRT or Core System Resources Table is a proprietary ACPI table introduced by Microsoft, but This table can contain devices that are not in the system DSDT table. In particular DMA controllers, Timer, interrupt might be described here. we can get DMA description from DMAR (DMA Remapping Table) tables on Intel platform, but on ARM SoCs, there is no table to describe DMA, only CSRT is available. Actually, the support code of CSRT in Linux kernel already have submitted by Intel on Jan 17 this year, but only DMA is supported, still have something more to do (if needed). So, why not use the CSRT table to describe DMA? Thanks Hanjun

[PATCH v2 0/6] Remove the duplicated _MAT evaluation and simplify _acpi_map_lsapic()

by Hanjun Guo

v1->v2: Return specific error value instead of just return -1, and correct some grammar mistake in changelog. For cpu hot add, evaluate _MAT or parse MADT will did twice to get APIC id: acpi_processor_add() acpi_processor_get_info() acpi_get_cpuid() will evaluate _MAT or parse MADT; acpi_processor_hotadd_init() acpi_map_lsapic() will evaluate _MAT again; This patch set introduces apic_id in struct processor to save parsed APIC id, and use it to remove the duplicated _MAT evaluation. Further more, the new logical cpu number will be generated in acpi_register_lapic(), this can be returned to remove the cpumask allocation and operation to simplify _acpi_map_lsapic(). There are also some cleanups for the ACPI processor dirver code.
