Dear all, Trying to port the xenomai on DB410c soc with kernel https://source.codeaurora.org/kernel/msm-4.9.git Ported the arm64 ipipe and xenomai patches. Trying to make soc related changes . Following ' https://gitlab.denx.de/Xenomai/xenomai/wikis/Porting_Xenomai_To_A_New_Arm_SOC#flow-handler' link to port xenomai on new SOC. Here we could find three interrupt controller drivers in which we need to add .mask and .unmask callbacks. - drivers/gpio/gpio-msm-smp2p.c - drivers/pinctrl/qcom/pinctrl-msm.c - drivers/irqchip/qcom/pdc.c 1. 'drivers/irqchip/qcom/pdc.c' made following changes to support xenomai. *---------------------- * *diff --git a/drivers/irqchip/qcom/pdc.c b/drivers/irqchip/qcom/pdc.c* *index ba7b6da..5772760 100644* *--- a/drivers/irqchip/qcom/pdc.c* *+++ b/drivers/irqchip/qcom/pdc.c* *@@ -40,7 +40,8 @@ enum pdc_register_offsets {* * IRQ_i_CFG = 0x110,* * };* *-static DEFINE_SPINLOCK(pdc_lock);* *+//static DEFINE_SPINLOCK(pdc_lock);* *+static IPIPE_DEFINE_SPINLOCK(pdc_lock);* * static void __iomem *pdc_base;* * static int get_pdc_pin(irq_hw_number_t hwirq, void *data)* *@@ -228,8 +229,14 @@ static struct irq_chip qcom_pdc_gic_chip = {* * .irq_disable = qcom_pdc_gic_disable,* * .irq_retrigger = irq_chip_retrigger_hierarchy,* * .irq_set_type = qcom_pdc_gic_set_type,* *+#ifdef CONFIG_IPIPE* *+ .irq_hold = qcom_pdc_gic_mask,* *+ .irq_release = qcom_pdc_gic_unmask,* *+#endif* *+* * .flags = IRQCHIP_MASK_ON_SUSPEND |* * IRQCHIP_SET_TYPE_MASKED |* *+ IRQCHIP_PIPELINE_SAFE |* * IRQCHIP_SKIP_SET_WAKE,* *----------------------* Not finding equivalent API for 'irq_domain_add_hierarchy'. *---------------------- * * pdc_domain = irq_domain_add_hierarchy(parent_domain, 0, MAX_IRQS,* * node, &qcom_pdc_ops, data);* *---------------------- * After this changes target is getting hang while booting. Could you please help me to port this driver ? Thanks, Ramappa _______________________________________________ Xenomai mailing list Xenomai@xenomai.org https://xenomai.org/mailman/listinfo/xenomai
