From: David Abdurachmanov <david.abdurachmanov@xxxxxxxxxx> The order of interrupt numbers is incorrect. The order for FU740 is: DirError, DataError, DataFail, DirFail >From SiFive FU740-C000 Manual: 19 - L2 Cache DirError 20 - L2 Cache DirFail 21 - L2 Cache DataError 22 - L2 Cache DataFail Signed-off-by: David Abdurachmanov <david.abdurachmanov@xxxxxxxxxx> Signed-off-by: Palmer Dabbelt <palmerdabbelt@xxxxxxxxxx> --- Olof pointed me to https://raw.githubusercontent.com/sifive/meta-sifive/2021.03/recipes-kernel/linux/files/unmatched/0009-riscv-dts-fu740-fix-cache-controller-interrupts.patch This appears necessary to make the FU740 function properly, but hasn't been posted on the mailing lists. Given the age I'm hoping it's just slipped through the cracks somewhere, but I figured I'd send it out to give David a chance to comment if there's a different plan. --- arch/riscv/boot/dts/sifive/fu740-c000.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/riscv/boot/dts/sifive/fu740-c000.dtsi b/arch/riscv/boot/dts/sifive/fu740-c000.dtsi index 8eef82e4199f..abbb960f90a0 100644 --- a/arch/riscv/boot/dts/sifive/fu740-c000.dtsi +++ b/arch/riscv/boot/dts/sifive/fu740-c000.dtsi @@ -273,7 +273,7 @@ ccache: cache-controller@2010000 { cache-size = <2097152>; cache-unified; interrupt-parent = <&plic0>; - interrupts = <19 20 21 22>; + interrupts = <19 21 22 20>; reg = <0x0 0x2010000 0x0 0x1000>; }; gpio: gpio@10060000 { -- 2.32.0.272.g935e593368-goog
