scripts/runqemu: Add snapshot support

2016-09-09T11:07:32+00:00

Allow access to the snapshot option of qemu to simplify some of our runtime testing to avoid copying images. (From OE-Core rev: 8fec4a5a004f0e99734f8c0820c66522d08f213e) Signed-off-by: Richard Purdie

runqemu: Enable virtio RNG for all platforms

2016-09-09T11:07:32+00:00

We have problems where systems simply stop booting and hang. This is due to a lack of entropy which means ssh keys and networking can't be brought up. Adding in the virtio-rng passthrough support allows host entropy to pass into the guess and avoids these hangs. This is particularly problematic after the gnutls upgrade which starts using /dev/random instead of /dev/urandom but was an issue we'd occasionally seem before that. It particualrly affected x86 and ppc machines for some reason. (From OE-Core rev: 51b001909f1856c45cf87091d6e4446c266d5786) Signed-off-by: Richard Purdie

runqemu: Allow unique network interface MAC addresses

2016-09-09T11:07:32+00:00

Current qemu instances all share the same MAC address. This shouldn't be an issue as they are all on separate network interfaces, however on the slight chance this is causing problems, its easy enough to ensure we use unique MAC addresses based on the IP numbers we assign.

runqemu: fix run from testimage with non-standard DEPLOY_DIR_IMAGE

2016-09-09T11:07:32+00:00

testimage.bbclass uses runqemu to execute runtime tests on a qemu target, this means that bitbake is already running and `bitbake -e` can't be called to obtain bitbake variables. runqemu tries to work around being unable to read values for bitbake variables by inferring the MACHINE from the DEPLOY_DIR_IMAGE setting, however if a user sets that variable in a manner which doesn't follow the systems expectations (i.e. if running `bitbake -c testimage` against a directory of pre-generated images in a user-specified path) the inferring of the MACHINE name from the DEPLOY_DIR_IMAGE location will fail. It's possible that check_arg_machine() shouldn't cause runqemu to fail and that runqemu should proceed with the user-supplied value even if it can't be verified. This patch simply ensures that a workflow where the user sets DEPLOY_DIR_IMAGE continues to work without changing too much of the runqemu code.

runqemu: fixes for when invoked during a bitbake run

2016-09-09T11:07:32+00:00

When runqemu is invoked from a running bitbake instance it will be unable to call `bitbake -e` due to the lock held by the calling bitbake instance. Our test code sets an OE_TMPDIR environment variable from which we can infer/guess paths. Add code to do so when self.bitbake_e can't be set, much as the sh version of runqemu did.

runqemu: better handle running on a host with different paths

2016-09-09T11:07:32+00:00

If the STAGING_*_NATIVE directories from the config file don't exist and we're in a sourced OE build directory try to extract the paths from `bitbake -e` (From OE-Core rev: 9326af1c20636320c70caecebd47aedafb3f2d25) Signed-off-by: Joshua Lock Signed-off-by: Richard Purdie

runqemu: assume artefacts are relative to *.qemuboot.conf

2016-09-09T11:07:32+00:00

When runqemu is started with a *.qemuboot.conf arg assume that image artefacts are relative to that file, rather than in whatever directory the DEPLOY_DIR_IMAGE variable in the conf file points to.

runqemu: refactor it and remove machine knowledge

2016-09-09T11:07:32+00:00

Previously, runqemu had hard coded machine knowledge, which limited its usage, for example, qemu can boot genericx86, but runqemu can't, we need edit runqemu/runqemu-internal a lot if we want to boot genericx86. Now bsp conf files can set vars to make it can be boot by runqemu, and qemuboot.bbclass will save these info to DEPLOY_DIR_IMAGE/qemuboot.conf. Please see qemuboot.bbclass' comments on how to set the vars. * Re-write it in python3, which can reduce lines from 1239 to about 750 lines * All the machine knowledges are gone * All of the TUN_ARCH knowledge are gone * All the previous options are preserved, and there is a new way to run runqemu: (it doesn't need run "bitake -e" in such a case) $ runqemu tmp/deploy/images/qemux86 or: $ runqemu tmp/deploy/images/qemuarm/.ext4 or: $ runqemu tmp/deploy/images/qemuarm/qemuboot.conf * Fixed audio support, not limited on x86 or x86_64 * Fix SLIRP mode, add help message, avoid mixing with tap * Fix NFS boot, it will extract .tar.bz2 or tar.gz to DEPLOY_DIR_IMAGE/-nfsroot when no NFS_DIR, and remove it after stop. * More bsps can be boot, such as genericx86 and genericx86-64. * The patch for qemuzynq, qemuzynqmp, qemumicroblaze has been sent to meta-xilinx' mailing list. * I can't find any qemush4 bsp or how to build it, so it is not considered atm.
