Do you have a packaged clang-19 toolchain? The x86_64 allyesconfig build succeeded for the robot, but when I build on x86_64 with gcc-11.4.0, I get an error: $ gcc -v gcc version 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04) $ git checkout 592aac418ebd $ make allyesconfig $ make drivers/pci/controller/pcie-rockchip-ep.o CC drivers/pci/controller/pcie-rockchip-ep.o drivers/pci/controller/pcie-rockchip-ep.c:640:9: error: implicit declaration of function ‘irq_set_irq_type’ irq_set_irq_type() is declared in <linux/irq.h>. On arm64, where this driver is used, <linux/irq.h> is included via this path: linux/pci.h linux/interrupt.h linux/hardirq.h arch/arm64/include/asm/hardirq.h asm-generic/hardirq.h linux/irq.h but on x86, arch/x86/include/asm/hardirq.h does not include asm-generic/hardirq.h and therefore doesn't include <linux/irq.h>. I'm confused about why the robot reported a successful build with clang-19. It seems like that should have the same problem I saw with gcc, so I'd like to try it manually. Bjorn
