qemuboot-intel: fix audio option

2022-03-30T14:41:35+00:00

-soundhw ac97 is deprecated since qemu v5.1.0. Replace it with recommended option. Fixes: | qemu-system-x86_64: warning: '-soundhw ac97' is deprecated, please use '-device AC97' instead Signed-off-by: Anuj Mittal

qemuboot-intel.inc: remove vga and uvesafb parameters

2021-11-16T16:01:19+00:00

These are ancient and no longer required.

qemuboot-intel: fix the override syntax

2021-08-09T15:09:49+00:00

Use : as per the new syntax. Signed-off-by: Anuj Mittal

Manually move some overrides to new syntax

2021-08-06T07:51:53+00:00

Some of these were missed when using the script and were noticed when building intel-skylake-64 and tiny images which had started failing. Signed-off-by: Anuj Mittal

qemuboot-intel.inc: remove deprecated show-cursor option

2021-06-25T08:59:58+00:00

Don't pass show-cursor as it's no longer a valid option. We pass the correct show-cursor=on in runqemu so remove it from here. Signed-off-by: Anuj Mittal

qemuboot-intel: use Skylake-Client instead of kvm64

2020-04-14T02:04:27+00:00

Use skylake-client instead of legacy kvm64 for intel-skylake-64 MACHINE. Also helps prevent problems when booting up using KVM in QEMU. Signed-off-by: Anuj Mittal

conf: add new machine intel-skylake-64

2019-08-21T04:30:01+00:00

Add 64-bit new machine (intel-skylake-64) with -march=skylake and avx2 instruction-set set up. We do see a qemu-usermode failure at build time, on setup of avx2 instruction-set as QEMU does not support AVX instruction set. Check this: https://bugs.launchpad.net/qemu/+bug/1818075 So to bypass this issue disabling qemu-usermode for intel-skylake-64 machine. Due to above limitation and in order to not affecting existing machines, this new machine is being proposed to add. A quick performance comparision between intel-corei7-64 vs intel-skylake-64 machines Measurements are in time, taken by the benchmark tests. Less is better.

meta-intel: Don't override default qemu slirp options

2017-03-01T00:05:01+00:00

The latest OE's runqemu script by default uses the following SLIRP options -netdev user,id=net0,hostfwd=tcp::2222-:22,hostfwd=tcp::2323-:23 which are suitable for meta-intel too. And what is more important they don't follow the deprecated syntax currently present in the option values overriden by meta-intel. The patch drops the meta-intel specific overrides.

meta-intel: enable qemu and select more suitable virtual machine options

2017-01-24T22:31:06+00:00

Although the machines definitions in meta-intel are meant to target real hardware, begin able to start the resulting images under qemu is nevertheless useful for testing. Doing that via runqemu depends on a per-image runqemu.conf that describes how to run qemu for the image. Ineriting qemuboot.bbclass in image recipes with QB_ variables set for the current architecture via overrides creates that file. The new qemuboot-intel.inc was copied from OE-core's qemuboot-x86.inc and adapted to the three common machines in meta-intel: $ diff ../openembedded-core/meta/conf/machine/include/qemuboot-x86.inc conf/machine/include/qemuboot-intel.inc 3,5c3,5 < QB_SYSTEM_NAME_x86 = "qemu-system-i386" < QB_CPU_x86 = "-cpu qemu32" < QB_CPU_KVM_x86 = "-cpu kvm32" --- > QB_SYSTEM_NAME_intel-core2-32 = "qemu-system-i386" > QB_CPU_intel-core2-32 = "-cpu coreduo" > QB_CPU_KVM_intel-core2-32 = "-cpu kvm32" 7,9c7,13 < QB_SYSTEM_NAME_x86-64 = "qemu-system-x86_64" < QB_CPU_x86-64 = "-cpu core2duo" < QB_CPU_KVM_x86-64 = "-cpu kvm64" --- > QB_SYSTEM_NAME_intel-corei7-64 = "qemu-system-x86_64" > QB_CPU_intel-corei7-64 = "-cpu Nehalem" > QB_CPU_KVM_intel-corei7-64 = "-cpu kvm64" > > QB_SYSTEM_NAME_intel-quark = "qemu-system-i386" > QB_CPU_intel-quark = "-cpu coreduo" > QB_CPU_KVM_intel-quark = "-cpu kvm32" For performance reasons, runqemu uses virtio for the boot disk. The kernel therefore must have the necessary drivers enabled. This may also be useful when running a meta-intel machine image on other virtual platforms and therefore the default kernel configuration gets changed to enable virtio. However, OE-core's qemu.inc also enables various other tweaks for running under qemu, like deriving the wired Ethernet address from the kernel boot parameters. This is probably less desirable for a meta-intel machine and thus not enabled in the new qemu-intel.inc. The downside is that the resulting images then come up without assigned IP address when used under qemu. Distros which want that feature can still add it to their images by copying settings from OE-core's qemu.inc. Signed-off-by: Patrick Ohly Signed-off-by: California Sullivan
