Subject: [edk2-devel] [PATCH v1 0/2] Add a new FdtNorFalshQemuLib and enable it in
Date: Fri, 17 May 2024 15:17:29 +0800 [thread overview]
Message-ID: <20240517071729.188409-1-lichao@loongson.cn> (raw)
Patch1: Added a new library called FdtNorFlashQemuLib in OvmfPkg/Library
which is non-hardcode dependency.
Patch2: Enable the new library in ArmVirtQemu.dsc and
ArmVirtQemuKernel.dsc.
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4770
I have verified on both of the two platforms:
Prepare:
install libvirt, virt-manager, qemu-systemaarch64.
Step 1:
Built the two platforms with ArmVirtQemu.dsc and
ArmVirtQemuKernel.dsc, and then using the command create the pflash
files:
Build the two platforms firmware using ArmVirtQemu.dsc and
ArmVirtQemuKernel.dsc, and then create the pflash files using following
command:
cat QEMU_EFI.fd /dev/zero | head -c 64m > ./QEMU_EFI-pflash.raw
cat QEMU_VARS.fd /dev/zero | head -c 64m > ./vars-template-pflash.raw
qemu-img convert -f raw -O qcow2 -o cluster_size=4096 -S 4096 QEMU_EFI-pflash.raw QEMU_EFI-pflash.qcow2
qemu-img convert -f raw -O qcow2 -o cluster_size=4096 -S 4096 vars-template-pflash.raw vars-template-pflash.qcow2
Download a AARCH64 QCOW2 image.
Copy them into /usr/share/edk2/aarch64/.
Step 2:
Verification the pflash working:
ArmVirtQemu:
Run the QEMU ARM virt machine using the following command:
qemu-system-aarch64 \
-blockdev '{"driver":"file","filename":"/usr/share/edk2/aarch64/QEMU_EFI-pflash.qcow2","node-name":"libvirt-pflash0-storage","auto-read-only":true,"discard":"unmap"}' \
-blockdev '{"node-name":"libvirt-pflash0-format","read-only":true,"driver":"qcow2","file":"libvirt-pflash0-storage"}' \
-blockdev '{"driver":"file","filename":"/usr/share/edk2/aarch64/vars-template-pflash.qcow2","node-name":"libvirt-pflash1-storage","auto-read-only":true,"discard":"unmap"}' \
-blockdev '{"node-name":"libvirt-pflash1-format","read-only":false,"driver":"qcow2","file":"libvirt-pflash1-storage"}' \
-machine virt,pflash0=libvirt-pflash0-format,pflash1=libvirt-pflash1-format,acpi=on \
-cpu cortex-a57 \
-m size=2097152k \
-serial stdio \
-net none \
-device ramfb \
-device nec-usb-xhci \
-device usb-mouse \
-device usb-kbd
ArmVirtQemuKernel:
Run the QEMU kernel ARM virt machine using the following command:
qemu-system-aarch64 \
-blockdev '{"driver":"file","filename":"/usr/share/edk2/aarch64/vars-template-pflash.raw","node-name":"libvirt-pflash1-storage","auto-read-only":true,"discard":"unmap"}' \
-blockdev '{"node-name":"libvirt-pflash1-format","read-only":false,"driver":"raw","file":"libvirt-pflash1-storage"}' \
-machine virt,usb=off,dump-guest-core=off,gic-version=3,pflash1=libvirt-pflash1-format \
-cpu cortex-a57 \
-m 4096 \
-smp 1,sockets=1,cores=1,threads=1 \
-no-user-config \
-nodefaults \
-device virtio-gpu-pci \
-kernel /usr/share/edk2/aarch64/QEMU_EFI-pflash.raw \
-serial stdio \
-device nec-usb-xhci \
-device usb-mouse \
-device usb-kbd \
-hda /usr/share/edk2/aarch64/openEuler-22.03-LTS-SP3-aarch64.qcow2 \
-monitor tcp::3333,server,nowait
Step 3:
After the virt-machines starts, enter "F2" to enter the setup UI, try to
change the boot order or some ther variables stored in the flash, then
enter "F10" to save the changes and reboot it.
After restarting, enter "F2" to enter the setup UI and check whether the
changes before the restart operation have been saved.
Using the above three steps, both platforms will works fine.
I have not created the PR in github yet, I will create it once the edk2
merge window reopens.
