qemu: set default RAM to 256M for all machines

2019-08-30T16:10:28+00:00

There was a discussion about what amount of RAM is appropriate for a default; the outcome was that for now it is still 256M. Some qemu machine definitions have however set this to 512M so for the sake of treating all architectures fairly, they are reset back to 256M. Also runqemu is adjusted to use 256M if QB_MEM is not set at all. http://lists.openembedded.org/pipermail/openembedded-core/2019-August/285900.html (From OE-Core rev: 04c01b6cc5be3e6d45d0e04571640648a5655a8b) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie

machine: clean up config files

Beautify the machine config files by making the names and descriptions more uniform and verbose (From OE-Core rev: 1108a24e2c58794163c8cf35154f8be5c1d06c29) Signed-off-by: Jon Mason Signed-off-by: Richard Purdie

qemuarm: Swap for an arm7ve (A15) configuration

2019-03-12T18:57:41+00:00

Add new QEMU BSP for a Arm Cortex-A15 system and use this as qemuarm, moving the old armv5te Versatile PB based machine to qemuarmv5. The new machine uses the QEMU virt machine type, which should be faster to emulate and updates the qemuarm support to a modern architecture.

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/bsp: update 4.15 preferred versions to 4.18

2018-08-28T09:30:28+00:00

4.18 is replacing 4.15 as the latest kernel in the upcoming release, so we update our preferred versions to match. (From OE-Core rev: e12f9e7ede7eea408d6a97233c7c8df97e8bfb26) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

meta: don't use deprecated functions from utils.bbclass

2018-01-30T11:50:11+00:00

These functions were moved to meta/lib/oe in 2010 and the base_* functions in utils.bbclass were intended to be a short-term compatibility layer. They're still used in a few places, so update the callers to use the new functions.

qemu: bump default version to 4.12

2017-08-23T11:06:51+00:00

Not all the qemu machines carry default kernel specifications. While we could drop these references, we'll bump them to 4.12 to pick up the latest and remove them in future commits.
