This patchset contains necessary code changes to support two-level (Indirection) table walk feature for device table. Shanker Donthineni (5): irqchip/gicv3-its: Introduce two helper functions for accessing BASERn irqchip/gicv3-its: Add a new function for parsing device table BASERn irqchip/gicv3-its: Split its_alloc_tables() into two functions irqchip/gicv3-its: Remove an unused argument 'node_name' irqchip/gicv3-its: Implement two-level(indirect) device table support drivers/irqchip/irq-gic-v3-its.c | 414 +++++++++++++++++++++++-------------- include/linux/irqchip/arm-gic-v3.h | 4 + 2 files changed, 266 insertions(+), 152 deletions(-) -- This patchset created on top of Marc Zyngier's branch https://git.kernel.org/cgit/linux/kernel/git/maz/arm-platforms.git/log/?h=irq/irqchip-4.7-rc1 I have tested the Indirection feature on Qualcomm Technologies QDF2XXX server platform.
