Usage

./vamos setup              # init submodules and udev rules
./vamos build kernel       # build boot.img
./vamos build system       # build system.img
./vamos flash kernel       # flash boot.img via EDL
./vamos flash system       # flash system.img via EDL
./vamos flash all          # flash both
./vamos profile diff A B   # diff two rootfs profiles

Kernel Patches

Patches in kernel/patches/ are applied in order to the Linux kernel tree. They follow this naming convention:

NNNN-SUBSYSTEM-description.patch
  • NNNN — sequential number, zero-padded (0001, 0002, …)
  • SUBSYSTEM — the area of the kernel being modified:
    • defconfig — kernel configuration files
    • dts — device tree sources
    • driver — driver changes
    • core — core kernel subsystem changes
  • description — short kebab-case summary of the change

Example: 0001-defconfig-add-vamos.patch
