So the stock kernel from the debian image doesn't boot with Xen and produces no output. Having it up for a couple minutes made the board quite hot as well. With the 4.1 kernel and associated dtb suggested on the Wiki I get the following crash: Xen 4.7.0-rc (c/s Mon May 23 12:07:20 2016 +0100 git:8478c94-dirty) EFI loader Using configuration file 'xen.cfg' hi6220-hikey.dtb: 0x000000007acaf000-0x000000007acba6e0 Image: 0x0000000079fb9000-0x000000007aca1c00 Xen 4.7.0-rc (XEN) Xen version 4.7.0-rc (root@lan) (aarch64-linux-gnu-gcc (Ubuntu/Linaro 5.3.1-14ubuntu2) 5.3.1 20160413) debug=n Wed Jun 1 03:22:25 UTC 2016 (XEN) Latest ChangeSet: Mon May 23 12:07:20 2016 +0100 git:8478c94-dirty (XEN) Processor: 410fd033: "ARM Limited", variant: 0x0, part 0xd03, 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: 0000000000001122 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: 10101105 40000000 01260000 02102211 (XEN) ISA Features: 02101110 13112111 21232042 01112131 00011142 00011121 (XEN) Using PSCI-1.0 for SMP bringup (XEN) Generic Timer IRQ: phys=30 hyp=26 virt=27 Freq: 1200 KHz (XEN) GICv2 initialization: (XEN) gic_dist_addr=00000000f6801000 (XEN) gic_cpu_addr=00000000f6802000 (XEN) gic_hyp_addr=00000000f6804000 (XEN) gic_vcpu_addr=00000000f6806000 (XEN) gic_maintenance_irq=25 (XEN) GICv2: 160 lines, 8 cpus, secure (IID 0200143b).
