I found that QEMU's latest version that I used supports A15. https://launchpad.net/qemu-linaro/+milestone/2011.10
New in this month's release: - Instructions introduced with the Cortex-A15 (ARM mode SDIV and UDIV, and the VFPv4 fused multiply-accumulate instructions VFMA, VFMS, VFNMA, VFNMS) are now supported in linux-user mode
No, it supports these instructions *in linux-user mode*. You're trying to use QEMU in system mode, where A15 is still not yet supported.
For your reference, I am attaching the working (without LPAE support) and non-working (with LPAE support) .config files.
Working without LPAE and not-working with LPAE is completely the expected behaviour.
Also, as i told that without LPAE support, Kernel boots properly for VE A9 or VE A15. But, I am not sure how to verify that it worked correctly for A15? I am looking for some cross checking method to ensure that it works for A15.
Boot the kernel on an A15 ARM Fast Model or an A15 FPGA.
