This patch series makes some enhancement to ITS configuration in the following aspects:
o make allocation of the ITS tables more sensible o replace magic numbers with sensible macros o guarantees a safe quiescent status before initializing an ITS
This patch series is based on Marc's branch[1], and tested on Hisilion ARM64 board with GICv3 ITS hardware.
[1] https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git irq/gic-fixes
v3 -> v4: o Spell out device table instead of DT to avoid misunderstanding o Change its_check_quiesced() to a more sensible name its_force_quiescent()
v2 -> v3: o drop the patch of tracing LPI enabling status since Vladimir Murzin had already posted a similar patch o fix several improper description issues
v1 -> v2: o rebase to Marc's GIC fix branch o drop size calculation for Device Table since Marc had already posted one o guarantees a safe quiescent status before initializing an ITS as Marc suggested, rather than register a reboot notifier o fix an issue about the enabling status of LPI feature
Yun Wu (5): irqchip: gicv3-its: zero itt before handling to hardware irqchip: gicv3-its: use 64KB page as default granule irqchip: gicv3-its: add limitation to page order irqchip: gicv3-its: define macros for GITS_CTLR fields irqchip: gicv3-its: support safe initialization
