Hi All, I'm trying to bring up camkes VM Linux guest on Firefly RK3399 board which is with a GICv3 ARMv8. I'm using the "rockpro64" target and my work is based on [1] and [2]. When I run the "capdl-loader-image-arm-rockpro64", there's error "Range not available at 0xfef10000, size 0x10000".
Bootstrapping kernel Booting all finished, dropped to user space Undelivered IRQ: 132 Install gic v3 [email protected]:595 Range not available at 0xfef10000, size 0x10000 vm_reserve_memory_at@guest_memory.c:328 Failed to allocate vm reservation: Unable to create vspace reservation at address 0xfef10000 of size 65536 vm_install_vgic_v3@vgic_v3.c:87 Error installing vgic Assertion failed: !err (/mnt/data3/projects/rk3399/build/seL4/camkes-vm-app/projects/vm/components/VM_Arm/src/main.c: main_continued: 1098) Here's my projects/seL4_projects_libs/libsel4vmmplatsupport/plat_include/rockpro64/sel4vmmplatsupport/plat/devices.h content: #define GIC_VERSION_3 #define GIC_PADDR 0xfee00000 #define GIC_DIST_PADDR (GIC_PADDR + 0x00000000) #define GIC_DIST_SIZE 0x10000 #define GIC_REDIST_PADDR 0xfef00000 #define GIC_REDIST_SIZE 0xC0000 #define GIC_REDIST_SGI_PADDR (GIC_REDIST_PADDR + 0x00010000) #define GIC_REDIST_SGI_SIZE 0x10000 I think the problem is related to GIC_REDIST_SIZE. I set it to 0xC0000 according to the rockpro64 device tree file in kernel/tools/dts/rockpro64.dts interrupt-controller@fee00000 { compatible = "arm,gic-v3"; #interrupt-cells = < 0x04 >; #address-cells = < 0x02 >; #size-cells = < 0x02 >; ranges; interrupt-controller; reg = < 0x00 0xfee00000 0x00 0x10000 0x00 0xfef00000 0x00 0xc0000 0x00 0xfff00000 0x00 0x10000 0x00 0xfff10000 0x00 0x10000 0x00 0xfff20000 0x00 0x10000 >; interrupts = < 0x01 0x09 0x04 0x00 >; phandle = < 0x01 >; I tried to reduce it to 0x10000 and it can boot to VM guest but the guest Linux will fail in gic_iterate_rdists() because it cannot read from GIC's GICR_TYPER register correctly. Did I miss anything? Any suggestion is highly appreciated. Thank you very much!
