# QEMU PPC64 emulator
|
||
|
|
This page describes how to build and run coreboot for QEMU/PPC64.
|
||
|
|
You can configure ELF payload via `make menuconfig` (make sure "ROM chip size"
|
||
|
|
is large enough).
|
||
|
|
|
||
|
|
## Running coreboot in QEMU
|
||
|
|
```bash
|
||
|
|
qemu-system-ppc64 -M powernv,hb-mode=on \
|
||
|
|
-cpu power9 \
|
||
|
|
-bios build/coreboot.rom \
|
||
|
|
-drive file=build/coreboot.rom,if=mtd \
|
||
|
|
-serial stdio \
|
||
|
|
-display none
|
||
|
|
```
|
||
|
|
|
||
|
|
- The default CPU in QEMU for AArch64 is a 604. You specify a suitable
|
||
|
|
PowerPC CPU via `-cpu power9`.
|
||
|
|
- By default Hostboot mode is off and it needs to be turned on to run coreboot
|
||
|
|
as a firmware rather than like an OS.
|
||
|
|
- `-bios` specifies initial program (bootloader should suffice, but whole image
|
||
|
|
works fine too).
|
||
|
|
- `-drive` specifies image for emulated flash device.
|
||
|
|
|
||
|
|
## Building coreboot
|
||
|
|
```bash
|
||
|
|
make defconfig KBUILD_DEFCONFIG=configs/config.emulation_qemu_power9
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
This builds coreboot with no payload.
