To Whom it May Concern: Hello, I am using a Texas Instruments K2E Keystone Eval board with Linux 4.19.59. It has a 32-bit ARM Cortex A15 processor. There is keystone specific code in the kernel in arch/arm/mm/pv-fixup-asm.s that executes during early_paging_init for LPAE support. This causes the kernel to switch its running 32-bit address space to a 36-bit address space and the hypervisor traps repeatedly and stops it from booting. I suspect this is because Xen only allowed for the original 32-bit memory range specified by the dom0 device tree. The 36-bit LPAE address is a fixed offset from the 32-bit address and is not physically different memory. Can you suggest any way to get through this problem? I am using the master branch of xen from earlier this year. Any help is greatly appreciated.
Thanks, Dave
