Hello,
This patch series allows KVM to work with ACPI on ARM64.
Currently, the firmware tables are parsed by the the virtual timer and virtual
GIC code in order to configure them correctly.
However the parsing of these tables is already done in the GIC and arch timer
drivers. This patch series introduces new helpers to retrieve the information
from the different drivers in order to avoid duplication of the parsing code.
To make the merge easier via the different trees, each patch modifies a single
subsystem. The suggested plan to merge the series is divided in 3 steps:
1) Patches #1-#2 are merged via the clocksource tree
Patches #2-#7 are merged via the irqchip tree
2) Patches #8-#9 are merge via the KVM tree
3) Patch #10 is merged via the clocksource tree.
For all the changes see in each patch.
Regards,
Julien Grall (10):
clocksource: arm_arch_timer: Gather KVM specific information in a
structure
clocksource: arm_arch_timer: Extend arch_timer_kvm_info to get the
virtual IRQ
irqchip/gic-v2: Gather ACPI specific data in a single structure
irqchip/gic-v2: Parse and export virtual GIC information
irqchip/gic-v3: Prefix all pr_* messages by "GICv3: "
irqchip/gic-v3: Gather all ACPI specific data in a single structure
irqchip/gic-v3: Parse and export virtual GIC information
KVM: arm/arm64: arch_timer: Rely on the arch timer to parse the
firmware tables
KVM: arm/arm64: vgic: Rely on the GIC driver to parse the firmware
tables
clocksource: arm_arch_timer: Remove arch_timer_get_timecounter
