scripts/runqemu: Using a cpio* rootfs has no special network

2016-09-23T13:55:46+00:00

When booting a system with the rootfs being of cpio* type the networking
setup should still work the same as for all other root filesystem types.
This change removes the clearing of the NETWORK_CMD variable allowing
for the slirp/tap setup to be provided to QEMU.

runqemu: Move virtio RNG to machine configuration

2016-09-23T13:55:44+00:00

Not all QEMU machines (outside of those available in OE-Core) are
capable of using the virtio-rng-pci device due to various machine models
not having a pci/virtio bus. This makes it such that the use of the
'-device virtio-rng-pci' flag to QEMU is machine specific.

This patch removes the general addition of the flag to all runqemu
targets and adds the flag into the QB_OPT_APPEND for all the qemu*
machines in OE-Core that support its use (which is all of them).

runqemu: don't fail during check_arg_machine()

2016-09-21T20:59:14+00:00

If DEPLOY_DIR_IMAGE doesn't exist during check_arg_machine() we
will attempt to guess a suitable value later when check_and_set()
calls validate_paths(), therefore this shouldn't raise an exception

runqemu: don't try and invoke bitbake when running in a toolchain env

2016-09-21T20:59:14+00:00

If a MACHINE value is passed we can't validate it by running bitbake
as the toolchain environment doesn't include the build system, we
must assume that the passed value for MACHINE is correct.

runqemu: try and guess qemu-system binary when MACHINE isn't set

2016-09-21T20:59:14+00:00

Emulate some logic from the prior, shell based, version of runqemu
to try and infer the correct setting for MACHINE from the kernel
and rootfs filenames.

runqemu: validate paths and attempt to infer unset paths

2016-09-21T20:59:14+00:00

We need to validate and ensure all paths are set regardless of
whether runqemu was invoked with a .qemuboot.conf file or
otherwise. Split this logic out into a separate method called
during check_and_set()

runqemu: improve finding of rootfs, kernel and dtb

2016-09-20T14:10:36+00:00

* Search rootfs in the following order:
  - IMAGE_NAME*.FSTYPE
  - IMAGE_LINK_NAME*.FSTYPE

* Search kernel in the following order:
  - QB_DEFAULT_KERNEL
  - KERNEL_IMAGETYPE
  - KERNEL_IMAGETYPE*

* Search dtb in the following order:
   - QB_DTB
   - QB_DTB*
   - *.dtb

* Fix DTB, it should only work with "-kernel" option.

runqemu: use OECORE_NATIVE_SYSROOT from sdk

2016-09-19T08:07:06+00:00

There is no STAGING_DIR_NATIVE or bitbake in a extracted sdk,
so check OECORE_NATIVE_SYSROOT and use it.

runqemu: work even if a *.qemuboot.conf isn't found

2016-09-19T08:07:06+00:00

A qemuboot conf file is a convenience but it should still be
possible to invoke runqemu without them, especially for examples
such as using the SDK with an extracted rootfs via NFS.

As read_qemuboot() is always called we need to be sure that function
can return cleanly, without throwing Exceptions, even if a qemuboot
conf file isn't found.

runqemu: try symlinks when kernel or rootfs can't be found

2016-09-19T08:07:06+00:00

If the kernel or rootfs names written to the qemuboot.conf can't
be found, try and find the symlinked variant of the filename.

This will help usability of runqemu, for example where a user
downloads an image and associated files as the symlinked names
yet the qemuboot.conf variables point to the full, non-linked,
file names.
