Subject: [PATCH 0/4] IRQ affinity support in PLIC driver
Date: Mon, 22 Oct 2018 17:15:13 +0530 [thread overview]
Message-ID: <20181022114517.22748-1-anup@brainfault.org> (raw)
This patchset primarily adds IRQ affinity support in PLIC driver and
other improvements.
The patchset gives mechanism for explicitly routing external interrupts to
particular CPUs using smp_affinity attribute of each Linux IRQs. Also, we
can now use IRQ balancer from kernel-space or user-space.
The patchset is tested on QEMU virt machine. It is based on Linux-4.19-rc2
and can be found at riscv_plic_irq_affinity_v1 branch of:
https://github.com/avpatel/linux.git
Anup Patel (4):
irqchip: sifive-plic: Pre-compute context hart base and enable base
irqchip: sifive-plic: More flexible plic_irq_toggle()
irqchip: sifive-plic: Differentiate between PLIC handler and context
irqchip: sifive-plic: Implement irq_set_affinity() for SMP host
