Re: Getting ACRN to work
Host MMU page size is 2MB in ACRN hypervisor. It seems to me that the direct cause for crash could be CONFIG_HV_RAM_START(0x13151000) is not 2MB aligned.
Did you disable relocation (RELOC in Kconfig)? By default RELOC is enabled and it allocates memory from EFI and overwrites the user defined CONFIG_HV_RAM_START, which is supposed to be able to avoid the 2MB alignment issue.
In case of you prefer to disable hypervisor relocation, you may need to make sure that CONFIG_HV_RAM_START is configured to the memory that is of EfiConventionalMemory(7) type. You may find out the available memory by calling dump_e820() in misc/efi-stub/boot.c, before emalloc_reserved_aligned().
