		Xvisor on ARM Fast Models Vexpress-A15 Host
		     (With Virtualization Extensions)

This section of readme explains how to build & run Xvisor for Vexpress-A15 
emulated by ARM Fast Models 7.0 or higher. 

By default, Xvisor for Vexpress-A15 supports Realview-PB-A8 guest so we will
show how to run Basic Firmware on Realview-PB-A8 guest. For more info refer,
<xvisor_source>/tests/arm32/realview-pb-a8/basic/README.

Please follow the steps below to build & run Xvisor on ARM Fast Models 
Vexpress-A15 Host:

  [1. Build environment for Xvisor]
  # CROSS_COMPILE=arm-none-linux-gnueabi-

  [2. GoTo Xvisor source directory]
  # cd <xvisor_source_directory>

  [3. Configure Xvisor with Vexpress-A15 default settings]
  # make ARCH=arm vexpress-a15-defconfig 

  [4. Build Xvisor]
  # make

  [5. Build Basic Firmware]
  # make -C tests/arm32/realview-pb-a8/basic

  [6. Create fast_model_boot.axf for running it on ARM Fast Models]
  # ./tools/scripts/memimg.py -a 0x80010000 -o build/fast_model_boot.img build/vmm.bin@0x80010000 build/tests/arm32/realview-pb-a8/basic/firmware.bin@0x81000000
  # cd build/; ${CROSS_COMPILE}gcc -nostdlib -march=armv7-a -mcpu=cortex-a15 -e start_boot -Wl,-Ttext=0x80000000 -DSPIN_LOOP_ADDR=0x84000000 -DVEXPRESS_A15 ../docs/arm/fast_model_boot.S -o fast_model_boot.axf; cd ..

  [7. Launch ARM fast models 7.0 or higher]
  # model_shell <your_fastmodel_dir>/FastModelsPortfolio_xxxx/examples/RTSM_VE/Build_Cortex-A15x1/Linux-Debug-GCC-<xxxx>/cadi_system_Linux-Debug-GCC-<xxxx>.so -C motherboard.smsc_91c111.enabled=1 -C motherboard.hostbridge.userNetworking=1 build/fast_model_boot.axf

  [8. Kick Guest0 for starting Basic Firmware]
  XVisor# guest kick guest0

  [9. Bind to virtual UART]
  XVisor# vserial bind guest0/uart0

  [10. Say 'hi' to Basic Firmware]
  [guest0/uart0] basic# hi

  [11. Say 'hello' to Basic Firmware]
  [guest0/uart0] basic# hello

  [12. Check various commands of Basic Firmware]
  [guest0/uart0] basic# help

  [13. Enter character seqence 'ESCAPE+x+q" return to Xvisor prompt]
  [guest0/uart0] basic#
