[PATCH v2 1/1] ACPI, PCI, ISA: Call ISA-specific code only for architectures which support ISA.

by Tomasz Nowicki

This commit moves ISA-specific code to separate function and makes that function depend on CONFIG_{E}ISA so that we do not have to maintain acpi_isa_irq_to_gsi() function for architectures which do not support ISA.

[Update][PATCH v5 5/5] ACPI: Replace printk with pr_* in tables.c

by Hanjun Guo

This patch just do some clean up to replace printk with pr_*, and introduces pr_fmt() to remove all PREFIXs in this file, no functional change. Signed-off-by: Hanjun Guo <hanjun.guo(a)linaro.org> --- Hi Rafael, I introduced pr_fmt() as Sudeep suggested, and remove all PREFIXs in this file, hope this patch is ok to you.

[PATCH v4 0/5] Prepare for running ACPI on !x86 and !ia64

by Hanjun Guo

Some of the ACPI code is arch-dependent and make the code can't be compiled on !x86 or !ia64, the first two patches just do some rework on the idle_boot_override and _PDC related stuff to make the ACPI code more arch-independent. The third patch just introduce map_gic_id() for ACPI processor core followed the ACPI 5.0 spec. Last two patches are just some cleanups. I have compiled the kernel successfully after appling this patch set on x86 and ia64. Changes for v4: a) remove preprocessor directives in function bodies; b) add another two patches for cleanups. Changes for v3: Fix the issues pointed out by Lan Tianyu and add the Reviewed-by for first patch. Changes for v2: a) add #if defined(CONFIG_X86) || defined(CONFIG_IA64) for idle_boot_override related code; b) Rebased on 3.14-rc1. Changes since the RFC version: a) Remove the RFC tag; b) Move idle_boot_override out of the arch directory suggested by Alan; c) Make these 3 patches as a separate patch set since there are not not related to the ARM/ARM64 platform. Hanjun Guo (5): ACPI / idle: Make idle_boot_override depend on x86 and ia64 ACPI / processor_core: Rework _PDC related stuff to make it more arch-independent ACPI / processor: Introduce map_gic_id() to get apic id from MADT or _MAT method ACPI: Move BAD_MADT_ENTRY() to linux/acpi.h ACPI: Replace printk with pr_* in tables.c arch/ia64/include/asm/acpi.h | 5 +-- arch/ia64/kernel/acpi.c | 18 ++++++-- arch/x86/include/asm/acpi.h | 19 +-------- arch/x86/kernel/acpi/boot.c | 4 -- arch/x86/kernel/acpi/cstate.c | 29 +++++++++++++ drivers/acpi/processor_core.c | 92 ++++++++++++++++++++++++----------------- drivers/acpi/tables.c | 51 +++++++++-------------- include/linux/acpi.h | 4 ++ 8 files changed, 124 insertions(+), 98 deletions(-) -- 1.7.9.5

leg-kernel tag leg-20140217.0 released

by Graeme Gregory

The leg-kernel release has been made and tagged as leg-20140217.0 This is based on mainline kernel v3.14-rc3 Repository : http://git.linaro.org/arm/acpi/leg-kernel.git Direct Link: https://git.linaro.org/arm/acpi/leg-kernel.git/commit/f7f2b0bff8dacdb0e5768… Notes :- 1) starting from this release, a FDT is not used to describe the platform. The kernel uses ACPI tables only. This release contains prototype code to boot the CPUs from information held in the MADT. It is hard coded to PSCI control method for the FVP base model.

leg-kernel tag leg-20140211.0 released

by Graeme Gregory

The leg-kernel release has been made and tagged as leg-20140211.0 This is based on mainline kernel v3.14-rc2 Repository : http://git.linaro.org/arm/acpi/leg-kernel.git Direct Link: http://git.linaro.org/arm/acpi/leg-kernel.git/commit/a48313884f9124e9703f8c… Notes :- 1) starting from this release, a FDT is not used to describe the platform. The kernel uses ACPI tables only. Given that current ACPI 5.0 tables have limitations in the MADT fields with regards to CPU topology for ARM platforms, currently this means that booting with ACPI will boot with only one processor running. This will remain until ACPI booting from PSCI prototype is completed. As hinted last month with the introduction of a dummy patch[1], the team is focusing on this and plans to present a prototype solution at LCA-14. Booting in FDT mode is unaffected.
