ACPI 5.1 has some major changes for ARM platform and the following
tables which are essential for ARM platforms:
1) MADT table updates for GIC v2/v3.
2) FADT updates for PSCI
3) GTDT for arch timer
This patch set is the ARM64 ACPI core patches covered MADT, FADT
and GTDT, platform board specific drivers are not covered by this
patch set.
We first introduce acpi.c and its related head file which are needed
by ACPI core, and then get RSDP to extract all the ACPI boot-time tables.
When all the boot-time tables (FADT, MADT, GTDT) are ready, then
parse them to init the sytem when booted. Specifically,
a) we use FADT to init PSCI and use PSCI to boot SMP;
b) Use MADT for GIC init and SMP init;
c) GTDT for arch timer init.
This patch set is based on 3.17-rc4 and was tested by Graeme on Juno
and FVP base model boot with ACPI only OK, if you want to test them,
you can pull from acpi-5.1-v5 branch in leg/acpi repo:
git://git.linaro.org/leg/acpi/acpi.git
Updates since v4:
- ACPI uasge doc for ARM64 was updated a lot by Al
- Collect some ACKs from Grant, Olof, Mark
- address some comments from Olof and Catalin since last version
Updates since v3:
- Compile out sleep.c on ARM64 when ACPI enabled
- refactor the GIC init code to address the comments from Marc and
Arnd
- refactor the SMP init code to fix some logic problem when PSCI is
not present, also address some of Grant and Lorenzo's comments
- reorder the patch series and move ACPI table changes to the front
of patch set
- rebase on top of 3.17-rc4
Updates since v2:
- Refactor the code to make SMP/PSCI init with less sperated init
path by Tomasz
- make ACPI depend on EXPERT
- Address lots of comments from Catalin, Sudeep, Geoff
- Add Juno device ACPI driver patches for review
Updates since v1:
- Set ACPI default off on ARM64 suggested by Olof;
- Rebase the patch set on top of linux-next branch/linux-pm tree which
includes the ACPICA for full ACPI 5.1 support.
- Update the document as suggested;
- Adress lots of comments from Mark, Sudeep, Randy, Naresh, Olof, Geoff
and more...
