sudo apt-get install git-email
sudo apt-get install libaio-dev libbluetooth-dev libbrlapi-dev libbz2-dev

kernel/initrd 相关

编译linux kernel及制作initrd

在ramdisk目录下，建立了所需文件后，可通过如下命令生成ramdisk

cd ramdisk
find . -print0 | cpio --null -ov --format=newc | gzip -9 > ../initrd-new3.img.gz

运行kernel

只运行kernel

./qemu/bin/debug/native/x86_64-softmmu/qemu-system-x86_64 -kernel ./linux-image/boot/vmlinuz-4.4.0-040400rc8-generic -append "console=ttyS0" -serial stdio

运行kernel+ramdisk

./qemu/bin/debug/native/x86_64-softmmu/qemu-system-x86_64 -enable-kvm -kernel ./linux-image/boot/vmlinuz-4.4.0-040400rc8-generic -initrd ./qemu_debug_linux/rootfs_64.img.gz -append "root=/dev/ram rdinit=/sbin/init console=ttyS0" -serial stdio

Troubleshooting

Error: uvesafb cannot reserve memory in qemu/kvm

Solution:

Check if you forgot to remove any vga=xxx kernel parameter -- this overrides the UVESA framebuffer with a standard VESA one.
Or try to add "video=vesa:off vga=normal" to kernel cmdline.

Error: "pci_root PNP0A08:00 address space collision + Uvesafb cannot reserve memory"

Solution:

This occurs on the qemu; whether it also occurs on other systems is unknown. Even without another framebuffer interfering with the uvesafb setup, uvesafb cannot reserve the necessary memory region.
You can fix this issue by adding the following to the kernel parameters in your bootloader's configuration.
pci=nocrs
