conf/machine: move tune files to architecture directories

2021-08-18T16:01:06+00:00

Move all of the tune files found in conf/machine/include into their respective architecture directories in that same location. All references to these will need to be updated. So, change the relevant ones for this tree in this commit as well. For the ARM tunes, nest them one further into armv8a, armv8m, etc. and rename some to make them uniform with the rest of the tunes.

qemuboot: Add QB_RNG variable

2020-09-24T21:32:49+00:00

RNG passthru has been enabled on all qemu machines but its being added to each one of them, with this patch its turned into QB variables which defaults to host passthru, yet it can be overridden if needed via machine or config metadata if needed.

qemu: uprev v4.2.0 -> v5.0.0

2020-06-23T11:31:03+00:00

Major update after v4.2. Changes: - os_find_datadir() was changed after the v4.2 release causing v5.0 to not find the bios and not boot the image. Fix is sent to upstream qemu. See: qemu/find_datadir.patch - v5.0 binary had host contamination for dynamically linked libraries, "--extra-ldflags='${LDFLAGS}'" in EXTRA_OECONF resolved the issue - bluetooth code was removed: qemu.git$ git show 1d4ffe8dc7 hence removed PACKAGECONFIG[bluez] - -show-cursor qemu option is now deprecated, updated scripts/runqemu to use updated option instead - added PACKAGECONFIG definitions - added qemu-ptest to conf/distro/include/ptest-packagelists.inc - increased support for ARM architecture, cpu and board - removed patches merged upstream and refreshed existing ones Testing: Build core-image-minimal against the machines in openembedded-core/meta/conf/machine and succesfully booted with qemu v5.0 Ran qemu-ptest on x86-64 and arm64 with identical results: PASS: 1166 SKIP: 0 FAIL: 0 (From OE-Core rev: ee9ec9e344541c1ccd9b9b8e3b8c1e00d008ad85) Signed-off-by: Sakib Sajal Signed-off-by: Joe Slater Signed-off-by: Richard Purdie

machine/qemu*: fix kernel finish crng init more and more slowly

2018-11-14T11:14:40+00:00

Just adding `-device virtio-rng-pci' to the QEMU invocation will add the device with a default host backend. As of QEMU 1.3+, the default backend is to use the host's /dev/random as a source of entropy. [1] When the entropy pool is empty, reads from /dev/random will block until additional environmental noise is gathered. [2] For Yocto, if call runqemu frequently, it will consume lots of host's /dev/random, and kernel finish crng init in guest get more and more slowly. Here are 4 times runqemu boot test: [ 3.464432] random: crng init done [ 20.874030] random: crng init done [ 23.583589] random: crng init done [ 23.858945] random: crng init done Modify entropy source to /dev/urandom device on the host which returns random bytes using a pseudorandom number generator seeded from the entropy pool. Reads from this device do not block and kernel finish crng init in guest will not delay. Of course, the side effect is obviously, we lost the quality of randomness, but the modification is only on runqemu script rather than real embedded device, and it benefits oeqa efficiency in which many cases call runqemu especially multiple oeqa builds on one host. After apply the fix: [ 3.364670] random: crng init done [ 4.619061] random: crng init done [ 3.403897] random: crng init done [ 3.450717] random: crng init done [1] https://wiki.qemu.org/Features/VirtIORNG [2] http://man7.org/linux/man-pages/man4/random.4.html (From OE-Core rev: 853644f82eb3205ef3efc1ea3959c7225dfacf61) Signed-off-by: Hongxu Jia Signed-off-by: Richard Purdie

qemu conf: replace deprecated option with new option

2017-08-19T21:15:39+00:00

runqemu: fixes for slirp, network device and hostfwd

2017-01-23T12:05:22+00:00

Fixed: - Add QB_NETWORK_DEVICE to set network device, it will be used by both slirp and tap. - Set QB_NETWORK_DEVICE to "-device virtio-net-pci" in qemuboot.bbclass but runqemu will default to "-device e1000" when QB_NETWORK_DEVICE is not set, this is because oe-core's qemu targets support virtio-net-pci, but the one outside of oe-core may not, "-device e1000" is more common. - Set hostfwd by default: 2222 -> 22, 2323 -> 23, and it will choose a usable port when the one like 222 is being used. This can avoid conflicts when multilib slirp qemus are running. We can forward more ports by default if needed, and bsp.conf can custom it. - Use different mac sections for slirp and tap to fix conflicts when running both of them on the same host.

Use weak assignment for SERIAL_CONSOLES in qemu configuration files

2016-12-13T22:55:20+00:00

Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that the value could serve as a default value and could be easily overridden in configuration files like local.conf. When using the default value for SERIAL_CONSOLES in qemux86-64,we would have annoying messages on console complaining about respawning getty on ttyS1. Although the value is set by purpose, at least we need to provide an easy way to override it.

runqemu: Move virtio RNG to machine configuration

2016-09-23T13:56:39+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).
