Subject: [PATCH 00/14] Implement generic IPI support mechanism
Date: Tue, 3 Nov 2015 11:12:47 +0000 [thread overview]
Message-ID: <1446549181-31788-1-git-send-email-qais.yousef@imgtec.com> (raw)
This series adds support for a generic IPI mechanism that can be used by both
arch and drivers to send IPIs to other CPUs.
The first 9 patches add the new functionality in the generic code.
Patches 10-13 make MIPS GIC irqchip driver support the new API and move MIPS
arch code to use the new generic IPI mechanism if the irqchip driver supports it.
Patch 14 adds IRQ-ipi.txt to Documentation explaining the new API and how to
make use of it.
This series is built on last RFC discussion[1]. I should have taken all
comments into account and hopefully haven't missed any.
This series is based on 4.3 irq/core.
Thanks,
Qais
