From d1ce73677cb476ba5e9d6bd20c90ecf1d17a694a Mon Sep 17 00:00:00 2001 From: Daniel Gonzalez Cabanelas Date: Mon, 18 May 2020 09:20:03 +0200 Subject: [PATCH] bcm63xx: periph_intc: report effective affinity MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The bcm6345-periph-intc driver only targets a single CPU at a time, even if the notional affinity is wider. Let's inform the core code about this. This patch gets rid of the kernel message: "genirq: irq_chip bcm6345-periph-intc did not update eff. affinity mask of irq 52" Signed-off-by: Daniel Gonzalez Cabanelas Signed-off-by: Álvaro Fernández Rojas (cherry picked from commit e04ff3c7cc52c23f5b40730ee426710e22940d68) --- ...-irqchip-bcm6345-report-eff-affinity.patch | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 target/linux/brcm63xx/patches-4.14/326-irqchip-bcm6345-report-eff-affinity.patch diff --git a/target/linux/brcm63xx/patches-4.14/326-irqchip-bcm6345-report-eff-affinity.patch b/target/linux/brcm63xx/patches-4.14/326-irqchip-bcm6345-report-eff-affinity.patch new file mode 100644 index 0000000000..f25488575c --- /dev/null +++ b/target/linux/brcm63xx/patches-4.14/326-irqchip-bcm6345-report-eff-affinity.patch @@ -0,0 +1,20 @@ +--- a/drivers/irqchip/irq-bcm6345-periph.c ++++ b/drivers/irqchip/irq-bcm6345-periph.c +@@ -186,6 +186,8 @@ static int bcm6345_periph_set_affinity(s + } + raw_spin_unlock_irqrestore(&priv->lock, flags); + ++ irq_data_update_effective_affinity(data, cpumask_of(cpu)); ++ + return 0; + } + #endif +@@ -197,6 +199,8 @@ static int bcm6345_periph_map(struct irq + + irq_set_chip_and_handler(irq, &priv->chip, handle_level_irq); + ++ irqd_set_single_target(irq_desc_get_irq_data(irq_to_desc(irq))); ++ + return 0; + } + -- 2.25.1
