5 | =================== | ||
6 | |||
7 | Changed default kernel provider from linux-yocto to linux-intel. | ||
8 | ---------------------------------------------------------------- | ||
9 | Linux-intel is an Intel(R)-maintained kernel based on the latest stable | ||
10 | branch, along with backports from upstream to better support Intel(R) | ||
11 | hardware. The intel-linux kernel also has a branch with the preempt-rt | ||
12 | patches applied, providing a preempt-rt kernel with no additional work. | ||
13 | |||
14 | Added QEMU support. | ||
15 | ------------------- | ||
16 | We now build several virtio drivers into the kernel by default, and | ||
17 | have qemuboot.conf files for intel-corei7-64 and intel-core2-32 | ||
18 | targets. This allows one to do basic testing on meta-intel images | ||
19 | without having to use hardware. The virtio drivers are added via | ||
20 | KERNEL_FEATURES_INTEL_COMMON. This prevents them from being added to | ||
21 | custom kernels by default. They can be removed by adding the | ||
22 | following to a conf or kernel bbappend file: | ||
23 | KERNEL_FEATURES_INTEL_COMMON_remove = “cfg/virtio.scc” | ||
24 | OVMF firmware is also built and can be used in order to emulate a UEFI | ||
25 | environment. A full runqemu command line for intel-corei7-64 could look | ||
26 | like this: | ||
27 | runqemu core-image-minimal intel-corei7-64 wic ovmf | ||
28 | |||
29 | Musl support | ||
30 | ------------ | ||
31 | Meta-intel is now compatible with the musl C library. You can specify musl | ||
32 | As your C library by adding the following to your local.conf: | ||
33 | TCLIBC = “musl” | ||
34 | Note: there is a known failure with DPDK. | ||
35 | |||
36 | X32 support | ||
37 | ----------- | ||
38 | The meta-intel layer can now build with the x32 tune settings in a multi-lib | ||
39 | setting, it will not work in as the primary MACHINE tune as the bootloader needs | ||
40 | to be built as a 64bit binary. The setup for this would be as follows: | ||
41 | require conf/multilib.conf | ||
42 | MULTILIBS = "multilib:libx32 | ||
43 | DEFAULTTUNE_virtclass-multilib-libx32 = "corei7-64-x32" | ||
