This file will only list major changes that occur within a release. For a full list of changes, view the git log of the repository. Rocko Release 11/2017 ===================== Moved qat support to separate layer ----------------------------------- Quick Assist Technology (QAT) is more middleware and should not be part of the core BSP. The new layer can be found here: https://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-qat/ Moved dpdk support to separate layer ------------------------------------ We had some requests to make DPDK standalone so that it could be included without bringing in anything else from meta-intel, as it is not specific to Intel(R) hardware. The new layer is located here: https://git.yoctoproject.org/cgit/cgit.cgi/meta-dpdk/ Added support for out-of-tree iwlwifi drivers --------------------------------------------- Backport-iwlwifi out-of-tree wifi modules are now available via meta-intel. Backport-iwlwifi brings the latest iwlwifi drivers to almost any kernel Note that mac80211 and cfg80211 backports are also necessary, which will most likely cause incompatibility with other in-tree wifi drivers. See https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi for more info. Added support for out-of-tree ixgbe drivers ------------------------------------------- The out-of-tree ixgbe drivers bring ixgbe support to nearly any kernel. See here: http://www.intel.com/network/connectivity/products/server_adapters.htm Added an implementation of Secure Boot -------------------------------------- meta-intel now supports a simple Secure Boot implementation. This implementation consists of a single binary consisting of an EFI stub, the kernel, an initrd, and a kernel command line. The binary is then signed via keys defined by the variables SECUREBOOT_SIGNING_KEY and SECUREBOOT_SIGNING_CERT. These keys should match the keys embedded in your hardware's firmware. See documentation/secureboot/README for more information on this feature. Improved Yocto Project Compatibility status ------------------------------------------- The common layer should now be considered Yocto Project compatible - it should no longer modify OE-core values when adding the layer to your bblayers.conf. The meta-tlk layer is still not Yocto Project compatible, however. Pyro Release 5/2017 =================== Changed default kernel provider from linux-yocto to linux-intel. ---------------------------------------------------------------- Linux-intel is an Intel(R)-maintained kernel based on the latest stable branch, along with backports from upstream to better support Intel(R) hardware. The intel-linux kernel also has a branch with the preempt-rt patches applied, providing a preempt-rt kernel with no additional work. Added QEMU support. ------------------- We now build several virtio drivers into the kernel by default, and have qemuboot.conf files for intel-corei7-64 and intel-core2-32 targets. This allows one to do basic testing on meta-intel images without having to use hardware. The virtio drivers are added via KERNEL_FEATURES_INTEL_COMMON. This prevents them from being added to custom kernels by default. They can be removed by adding the following to a conf or kernel bbappend file: KERNEL_FEATURES_INTEL_COMMON_remove = “cfg/virtio.scc” OVMF firmware is also built and can be used in order to emulate a UEFI environment. A full runqemu command line for intel-corei7-64 could look like this: runqemu core-image-minimal intel-corei7-64 wic ovmf Musl support ------------ Meta-intel is now compatible with the musl C library. You can specify musl As your C library by adding the following to your local.conf: TCLIBC = “musl” Note: there is a known failure with DPDK. X32 support ----------- The meta-intel layer can now build with the x32 tune settings in a multi-lib setting, it will not work in as the primary MACHINE tune as the bootloader needs to be built as a 64bit binary. The setup for this would be as follows: require conf/multilib.conf MULTILIBS = "multilib:libx32 DEFAULTTUNE_virtclass-multilib-libx32 = "corei7-64-x32"
