The following commit has been merged into the irq/core branch of tip: Commit-ID: 35d77eb7b974f62aaef5a0dc72d93ddb1ada4074 Gitweb: https://git.kernel.org/tip/35d77eb7b974f62aaef5a0dc72d93ddb1ada4074 Author: Anup Patel <apatel@xxxxxxxxxxxxxxxx> AuthorDate: Sat, 13 Apr 2024 12:22:10 +05:30 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitterDate: Sun, 14 Apr 2024 13:28:49 +02:00 irqchip/riscv-imsic: Fix boot time update effective affinity warning Currently, the following warning is observed on the QEMU virt machine: genirq: irq_chip APLIC-MSI-d000000.aplic did not update eff. affinity mask of irq 12 The above warning is because the IMSIC driver does not set the initial value of effective affinity in the interrupt descriptor. To address this, initialize the effective affinity in imsic_irq_domain_alloc().
