Notes for test-runner usage

---

Kernel configuration

The test-runner tool requires a kernel that is at least build with these minimal options for a successful boot.

CONFIG_VIRTIO=y
CONFIG_VIRTIO_PCI=y

CONFIG_NET=y
CONFIG_INET=y

CONFIG_NET_9P=y
CONFIG_NET_9P_VIRTIO=y

CONFIG_9P_FS=y
CONFIG_9P_FS_POSIX_ACL=y

CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_PCI=y
CONFIG_SERIAL_8250_NR_UARTS=4

CONFIG_TMPFS=y
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_TMPFS_XATTR=y

CONFIG_DEVTMPFS=y
CONFIG_DEBUG_FS=y

For Bluetooth functionality:

CONFIG_BT=y
CONFIG_BT_BREDR=y
CONFIG_BT_RFCOMM=y
CONFIG_BT_BNEP=y
CONFIG_BT_HIDP=y
CONFIG_BT_LE=y

CONFIG_BT_HCIVHCI=y

CONFIG_CRYPTO_CMAC=y
CONFIG_CRYPTO_USER_API=y
CONFIG_CRYPTO_USER_API_HASH=y
CONFIG_CRYPTO_USER_API_SKCIPHER=y

CONFIG_UNIX=y

CONFIG_UHID=y

These options should be installed as .config in the kernel source directory followed by this command.

make olddefconfig

After that a default kernel with the required options can be built. More option (like the Bluetooth subsystem) can be enabled on top of this.

Lock debuging

To catch locking related issues the following set of kernel config options may be useful:

CONFIG_LOCKDEP_SUPPORT=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_LOCK_ALLOC=y
CONFIG_PROVE_LOCKING=y
CONFIG_LOCKDEP=y
CONFIG_DEBUG_MUTEXES=y
