From: anup@brainfault.org (Anup Patel) To: linux-riscv@lists.infradead.org Subject: [PATCH v2 0/4] IRQ affinity support in PLIC driver Date: Tue, 27 Nov 2018 15:33:13 +0530 [thread overview] Message-ID: <20181127100317.12809-1-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-4.20-rc4 and can be found at riscv_plic_irq_affinity_v2 branch of: https://github.com/avpatel/linux.git Changes since v1: - Removed few whitspace changes from PATCH1 - Keep use of DEFINE_PER_CPU() as it is 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 drivers/irqchip/irq-sifive-plic.c | 144 ++++++++++++++++++------------ 1 file changed, 86 insertions(+), 58 deletions(-) -- 2.17.1
