For example to debug a processor boot issue, the ready and handover interrupts are checked for sanity to ensure the firmware reached a specific initialization stage. Remove "smp2p" string from the irq request so that the irq will default to the device name. Add an .irq_print_chip() callback to print the irq chip name as the device name. These two changes allow for a unique name to be used in /proc/interrupts as shown below. / # cat /proc/interrupts | grep smp2p 18: ... ipcc 196610 Edge smp2p-adsp 20: ... ipcc 131074 Edge smp2p-modem 170: ... smp2p-modem 1 Edge q6v5 ready 178: ... smp2p-adsp 1 Edge q6v5 ready Signed-off-by: Chris Lew Signed-off-by: Sudeepgoud Patil --- drivers/soc/qcom/smp2p.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) -- diff --git a/drivers/soc/qcom/smp2p.c b/drivers/soc/qcom/smp2p.c index a21241cbeec7..696c2a8387d0 100644 --- a/drivers/soc/qcom/smp2p.c +++ b/drivers/soc/qcom/smp2p.c @@ -16,6 +16,7 @@ #include #include #include +#include #include #include #include @@ -353,11 +354,19 @@ static int smp2p_set_irq_type(struct irq_data *irqd, unsigned int type) return 0; } +static void smp2p_irq_print_chip(struct irq_data *irqd, struct seq_file *p) +{ + struct smp2p_entry *entry = irq_data_get_irq_chip_data(irqd); + + seq_printf(p, " %8s", dev_name(entry->smp2p->dev)); +} + static struct irq_chip smp2p_irq_chip = { .name = "smp2p", .irq_mask = smp2p_mask_irq, .irq_unmask = smp2p_unmask_irq, .irq_set_type = smp2p_set_irq_type, + .irq_print_chip = smp2p_irq_print_chip, }; static int smp2p_irq_map(struct irq_domain *d, @@ -617,7 +626,7 @@ static int qcom_smp2p_probe(struct platform_device *pdev) ret = devm_request_threaded_irq(&pdev->dev, irq, NULL, qcom_smp2p_intr, IRQF_ONESHOT, - "smp2p", (void *)smp2p); + NULL, (void *)smp2p); if (ret) { dev_err(&pdev->dev, "failed to request interrupt\n"); goto unwind_interfaces;
