Hello Andrii, 2019年1月29日(火) 22:30 Andrii Anisov <andrii.anisov@xxxxxxxxx>: Hello Jairo, As you correctly pointed out, I was using an older version of a dtb file which didn't have the memory modification. I was able to check that the dtb file I was using was finally correct by utilizing dtc on the compiled dtb. dtc -I dtb -O dts -o test.dtb r8a7796-m3ulcb-xen-local.dtb It seems that finally Xen was able to boot with the Dom0 Linux also somewhat booting. At the end I get a p2m.c error repeatedly which loops the machine. The complete output is below: - UART enabled - - CPU 00000000 booting - - Current EL 00000008 - - Xen starting at EL2 - - Zero BSS - - Setting up control registers - - Turning on paging - - Ready - (XEN) Checking for initrd in /chosen (XEN) RAM: 0000000048000000 - 000000007fffffff (XEN) RAM: 0000000600000000 - 000000063fffffff (XEN) (XEN) MODULE[0]: 0000000048000000 - 0000000048011000 Device Tree (XEN) MODULE[1]: 000000007a000000 - 000000007c000000 Kernel (XEN) RESVD[0]: 0000000048000000 - 0000000048011000 (XEN) (XEN) (XEN) Command line: dom0_mem=752M console=dtuart dtuart=serial0 dom0_max_vcpus=4 (XEN) PFN compression on bits 19...20 (XEN) Domain heap initialised (XEN) Booting using Device Tree (XEN) Platform: Generic System (XEN) Looking for dtuart at "serial0", options "" Xen 4.12.0-rc (XEN) Xen version 4.12.0-rc (jelfn@xxxxxxxxx) (aarch64-poky-linux-gcc (GCC) 7.3.0) debug=y Tue Jan 29 01:08:01 JST 2019 (XEN) Latest ChangeSet: Fri Jan 18 12:47:45 2019 +0000 git:1912f12-dirty (XEN) Processor: 411fd073: "ARM Limited", variant: 0x1, part 0xd07, rev 0x3 (XEN) 64-bit Execution: (XEN) Processor Features: 0000000000002222 0000000000000000 (XEN) Exception Levels: EL3:64+32 EL2:64+32 EL1:64+32 EL0:64+32 (XEN) Extensions: FloatingPoint AdvancedSIMD (XEN) Debug Features: 0000000010305106 0000000000000000 (XEN) Auxiliary Features: 0000000000000000 0000000000000000 (XEN) Memory Model Features: 0000000000001124 0000000000000000 (XEN) ISA Features: 0000000000011120 0000000000000000 (XEN) 32-bit Execution: (XEN) Processor Features: 00000131:00011011 (XEN) Instruction Sets: AArch32 A32 Thumb Thumb-2 Jazelle (XEN) Extensions: GenericTimer Security (XEN) Debug Features: 03010066 (XEN) Auxiliary Features: 00000000 (XEN) Memory Model Features: 10201105 40000000 01260000 02102211 (XEN) ISA Features: 02101110 13112111 21232042 01112131 00011142 00011121 (XEN) Using SMC Calling Convention v1.1 (XEN) Using PSCI v1.0 (XEN) SMP: Allowing 6 CPUs (XEN) Generic Timer IRQ: phys=30 hyp=26 virt=27 Freq: 8333 KHz (XEN) GICv2 initialization: (XEN) gic_dist_addr=00000000f1010000 (XEN) gic_cpu_addr=00000000f1020000 (XEN) gic_hyp_addr=00000000f1040000 (XEN) gic_vcpu_addr=00000000f1060000 (XEN) gic_maintenance_irq=25 (XEN) GICv2: Adjusting CPU interface base to 0xf102f000 (XEN) GICv2: 512 lines, 8 cpus, secure (IID 0200043b).
