Hi,
I have the below setup for Linux inmate:
* Use initramfs
* UART is enabled
* eMMC is enabled
In the inmate cell I have the below:
.irqchips = {
/* GIC */ {
.address = 0xf1010000,
.pin_base = 128,
.pin_bitmap = {
1 << (153+32 - 160), /* SCIF1 - SPI153 */
},
},
/* GIC */ {
.address = 0xf1010000,
.pin_base = 160,
.pin_bitmap = {
1 << (168+32 - 192), /* SDHI3 - SPI168 */
},
},
},
And in the inmate DTS I have the below:
scif1: serial@e6e68000 {
compatible = "renesas,scif-r8a774a1",
"renesas,rcar-gen3-scif", "renesas,scif";
reg = <0 0xe6e68000 0 0x40>;
interrupt-parent = <&gic>;
interrupts = <GIC_SPI 153 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cpg CPG_MOD 206>,
<&cpg CPG_CORE R8A774A1_CLK_S3D1>,
<&scif_clk>;
clock-names = "fck", "brg_int", "scif_clk";
power-domains = <&sysc R8A774A1_PD_ALWAYS_ON>;
resets = <&cpg 206>;
pinctrl-0 = <&scif1_pins>;
pinctrl-names = "default";
};
gic: interrupt-controller@f1010000 {
compatible = "arm,gic-400";
#interrupt-cells = <3>;
#address-cells = <0>;
interrupt-controller;
reg = <0x0 0xf1010000 0 0x1000>,
<0x0 0xf102f000 0 0x20000>,
<0x0 0xf1040000 0 0x20000>,
<0x0 0xf106f000 0 0x20000>;
interrupts = <GIC_PPI 9
(GIC_CPU_MASK_SIMPLE(6) | IRQ_TYPE_LEVEL_HIGH)>;
};
When Linux is started on the inmate cell, I can see its booting through but
it doesn't fall into shell.
--- a/drivers/irqchip/irq-gic.c
+++ b/drivers/irqchip/irq-gic.c

+ pr_err(">>>>>>>>>>>>>>>>%s We received
IRQ:%u<<<<<<<<<<<<<<\n", __func__, irqnr);
+

break;
I added the above and I can see the Linux inmate receives only 0/1/27
interrupts.
Which gives me a feeling the Linux inmate isn't receiving the required
interrupts.
Any pointers on where I should be looking into?
Cheers,
Prabhakar
