Looking at the logs, Xen is placed differently in the memory: - Xen 4.8: 0x1aa0 - Xen 4.11: 0x00021fe0 With Xen 4.11, the binary will be placed above 4GB. There was some change in the way to place Xen in the memory in 2016 allowing to place Xen at the end of the usable RAM. I suspect the firmware does not support 64-bit address entry point for secondary CPU. This would explain the ADDRESS_INVALID from PSCI CPU UP call.

This means Xen gave an invalid entry point to PSCI CPU_UP. It would be interesting to know where Xen is loaded in memory with Xen 4.8 and Xen 4.11. This will be printed when early printk is enabled as the console is not yet setup. To get early printk, you could use CONFIG_EARLY_PRINTK=hikey960 on the make command line. Note this requires to have debug enabled. Once you have early printk setup you should have a message similar to "Update BOOTMOD_XEN from ... to ...". Also, as Konrad suggested it, I would recommend to bisect Xen and see if you can pin point a commit.

[Xen-devel] Armv8-A: Not able to enable secondary CPUs in Hikey960 board
Hi, I am using Hikey960 board and i started trying to port xen on hykey960. I followed all procedure has given in https://wiki.xenproject.org/wiki/HiKey960 link. And using *Xen version 4.11.1-pre *and linux as mentioned in above link. But, After flashing, I ended up with secondary CPUs errors and linux Dom0 errors. Please give some suggestions to start xen with all CPUs. Please check below log: Using modules provided by bootloader in FDT Xen 4.11.1-pre (c/s Mon Jul 30 11:30:09 2018 +0200 git:33ced72) EFI loader Xen 4.11.1-pre (XEN) Xen version 4.11.1-pre (omkar.bolla@) (aarch64-linux-gnu-gcc (Linaro GCC 7.1-2017.05) 7.1.1 20170510) debug=n Sat Aug 11 20:35:10 IST 201 8 (XEN) Latest ChangeSet: Mon Jul 30 11:30:09 2018 +0200 git:33ced72 (XEN) Processor: 410fd034: "ARM Limited", variant: 0x0, part 0xd03, rev 0x4 (XEN) 64-bit Execution: (XEN) Processor Features: (XEN) Exception Levels: EL3:64+32 EL2:64+32 EL1:64+32 EL0:64+32 (XEN) Extensions: FloatingPoint AdvancedSIMD (XEN) Debug Features: 10305106 (XEN) Auxiliary Features: (XEN) Memory Model Features: 1122 (XEN) ISA Features: 00011120 (XEN) 32-bit Execution: (XEN) Processor Features: 0131:00011011 (XEN) Instruction Sets: AArch32 A32 Thumb Thumb-2 Jazelle (XEN) Extensions: GenericTimer Security (XEN) Debug Features: 03010066 (XEN) Auxiliary Features: (XEN) Memory Model Features: 10201105 4000 0126 02102211 (XEN) ISA Features: 02101110 13112111 21232042 01112131 00011142 00011121 (XEN) Using SMC Calling Convention v1.1 (XEN) Using PSCI v1.1 (XEN) SMP: Allowing 8 CPUs (XEN) Generic Timer IRQ: phys=30 hyp=26 virt=27 Freq: 1920 KHz (XEN) GICv2 initialization: (XEN) gic_dist_addr=e82b1000 (XEN) gic_cpu_addr=e82b2000 (XEN) gic_hyp_addr=e82b4000 (XEN) gic_vcpu_addr=e82b6000 (XEN) gic_maintenance_irq=25 (XEN) GICv2: 384 lines, 8 cpus, secure (IID 0200143b).
