But just a random thought: Is it possible that you need to provide the console=hvc0 for the boot cmdline of dom0? dom0 needs share the serial port with Xen. > > I am loading Xen at top of the ram and linux and device tree at their > default locations (near starting of ram). > > This is the Xen BootLog which I receive through the earlyprintk serial port > - > > - UART enabled - > - CPU 00000000 booting - > - Xen starting in Hyp mode - > - Zero BSS - > - Setting up control registers - > - CPU Init Done -- Turning on paging - > - Ready - > (XEN) Checking for initrd in /chosen > (XEN) RAM: 0000000080000000 - 00000000ffefffff > (XEN) > (XEN) MODULE[0]: 0000000082000000 - 0000000082010000 Device Tree > (XEN) MODULE[1]: 0000000081000000 - 0000000081544448 Kernel > (XEN) RESVD[0]: 0000000082000000 - 0000000082010000 > (XEN) > (XEN) Command line: <NULL> > (XEN) Placing Xen at 0x00000000ffc00000-0x00000000ffe00000 > (XEN) Update BOOTMOD_XEN from 00000000fd000000-00000000fd0f9701 => > 00000000ffc00000-00000000ffcf9701 > (XEN) Xen heap: 00000000fa000000-00000000fe000000 (16384 pages) > (XEN) Dom heap: 507648 pages > (XEN) Domain heap initialised > (XEN) Platform: TEGRA124 > (XEN) No dtuart path configured > (XEN) Bad console= option 'dtuart' > Xen 4.6-unstable > (XEN) Xen version 4.6-unstable (root@) (arm-linux-gnueabihf-gcc > (Ubuntu/Linaro 4.7.3-11ubuntu1) 4.7.3) debug=y Fri Mar 11 10:09:07 UTC 2016 > (XEN) Latest ChangeSet: > (XEN) Processor: 413fc0f3: "ARM Limited", variant: 0x3, part 0xc0f, rev 0x3 > (XEN) 32-bit Execution: > (XEN) Processor Features: 00001131:00011011 > (XEN) Instruction Sets: AArch32 A32 Thumb Thumb-2 ThumbEE Jazelle > (XEN) Extensions: GenericTimer Security > (XEN) Debug Features: 02010555 > (XEN) Auxiliary Features: 00000000 > (XEN) Memory Model Features: 10201105 40000000 01240000 02102211 > (XEN) ISA Features: 02101110 13112111 21232041 11112131 10011142 00000000 > (XEN) Using PSCI-0.1 for SMP bringup > (XEN) Generic Timer IRQ: phys=30 hyp=26 virt=27 Freq: 12000 KHz > (XEN) GICv2 initialization: > (XEN) gic_dist_addr=0000000050041000 > (XEN) gic_cpu_addr=0000000050042000 > (XEN) gic_hyp_addr=0000000050044000 > (XEN) gic_vcpu_addr=0000000050046000 > (XEN) gic_maintenance_irq=25 > (XEN) GICv2: 192 lines, 4 cpus, secure (IID 0000043b). > (XEN) Using scheduler: SMP Credit Scheduler (credit) > (XEN) I/O virtualisation disabled > (XEN) Allocated console ring of 32 KiB. > (XEN) VFP implementer 0x41 architecture 4 part 0x30 variant 0xf rev 0x0 > (XEN) Bringing up CPU1 > - CPU 00000001 booting - > - Xen starting in Hyp mode - > - Setting up control registers - > - CPU Init Done -- Turning on paging - > - Ready - > (XEN) CPU 1 booted. > (XEN) Bringing up CPU2 > - CPU 00000002 booting - > - Xen starting in Hyp mode - > - Setting up control registers - > - CPU Init Done -- Turning on paging - > - Ready - > (XEN) CPU 2 booted. > (XEN) Bringing up CPU3 > - CPU 00000003 booting - > - Xen starting in Hyp mode - > - Setting up control registers - > - CPU Init Done -- Turning on paging - > - Ready - > (XEN) CPU 3 booted. > (XEN) Brought up 4 CPUs > (XEN) P2M: 40-bit IPA > (XEN) P2M: 3 levels with order-1 root, VTCR 0x80003558 > (XEN) *** LOADING DOMAIN 0 *** > (XEN) Loading kernel from boot module @ 0000000081000000 > (XEN) Allocating 1:1 mappings totalling 128MB for dom0: > (XEN) BANK[0] 0x00000088000000-0x00000090000000 (128MB) > (XEN) Additional MMIO 40000-40040 (IRAM) > (XEN) Additional MMIO 54200-54240 (Display A) > (XEN) Additional MMIO 54240-54280 (Display B) > (XEN) Additional MMIO 6000f-60010 (EXCEPTION VECTORS) > (XEN) Additional MMIO 6000c-6000d (SYSREG) > (XEN) Additional MMIO 1000-1001 (PCI CFG0) > (XEN) Additional MMIO 1001-1002 (PCI CFG1) > (XEN) Additional MMIO 12000-12010 (PCI IO) > (XEN) Additional MMIO 13000-20000 (PCI MEM) > (XEN) Additional MMIO 20000-40000 (PCI MEM (PREFETCH)) > (XEN) Additional IRQ 105 (DISPLAY) > (XEN) TEGRA: Routing IRQ105 to dom0, ICTLR2, mask 0x000200 > (XEN) Additional IRQ 106 (DISPLAY B) > (XEN) TEGRA: Routing IRQ106 to dom0, ICTLR2, mask 0x000400 > (XEN) Loading zImage from 0000000081000000 to > 000000008fa00000-000000008ff44448 > (XEN) Allocating PPI 16 for event channel interrupt > (XEN) Loading dom0 DTB to 0x000000008f800000-0x000000008f80f4a4 > (XEN) Scrubbing Free RAM on 1 nodes using 4 CPUs > (XEN) ....done. > (XEN) Initial low memory virq threshold set at 0x4000 pages. > (XEN) Std.

But is dom0 booted up? If you have network, can you connect to it? If dom0 did boot up, then at least we know it's some configuration issue. Again, I haven't tried on ARM yet, but I'd love to... :-) Best, Meng -- Meng Xu PhD Student in Computer and Information Science University of Pennsylvania http://www.cis.upenn.edu/~mengxu/ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
