[PATCH 0/2] irqchip/gic-v3: Fix selection of partition domain for EPPIs
From: James Morse
Date: Thu Jul 29 2021 - 13:28:18 EST
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,
