Subject: [PATCH 0/2] irqchip/gic-v3: Fix selection of partition domain for EPPIs
Date: Thu, 29 Jul 2021 17:27:46 +0000	[thread overview]
Message-ID: <20210729172748.28841-1-james.morse@arm.com> (raw)

Hello!

gic_irq_domain_translate()'s GIC_IRQ_TYPE_PARTITION code knows about EPPI, and
gic_populate_ppi_partitions() sets them up, but gic_irq_domain_select() and
partition_domain_translate() didn't get the memo, meaning partitioned EPPI
don't work.

I'm not aware of a platform affected by this, so I don't think its stable
material.

Based on rc1, available here:

git://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git irqchip/ppi_partition/eppi_fixes/v1


Thanks,

James Morse (2):
