OpenEmbedded/Yocto Distribution layer for Mentor Graphics
=========================================================
This layer holds the Mentor Embedded Linux distro configuration and
supplementary files, and acts as a staging area for changes which Mentor
Graphics requires, but which have not yet been merged into the upstream
layers.
This layer depends on:
URI: git://git.openembedded.org/openembedded-core
Branch: master
URI: git://git.openembedded.org/meta-openembedded
Revision: master
To bypass the meta-oe dependency:
BBMASK = "/meta-mentor/recipes/busybox/"
Contributing
------------
Browse url: http://git.yoctoproject.org/cgit/cgit.cgi/meta-mentor
Clone url: git://git.yoctoproject.org/meta-mentor.git
To contribute to this layer you should the patches for review to the
mailing list.
Mailing list: meta-mentor@yoctoproject.org
When sending single patches, please use something like
'git send-email -1 --to meta-mentor@yoctoproject.org'
When sending a series, please use poky/meta/scripts/create-pull-request (aka
oe-core/scripts/create-pull-request).
Content Review
--------------
Distro bits
===========
- base-files: issue files
- netbase: adjusted default interfaces file
- psplash: mel splash image
- core-image-base: added package-management
- e2fsprogs: killed e2fsprogs compat dep on blkid/badblocks
- mel-release: used to archive up content for release
- nfs-utils and packagegroup-core-nfs: prefer rpcbind, not portmap
- other packagegroups
- cml1-merge class: old crude implementation of defconfig file snippets,
ala *.cfg in kernel-yocto, but also useful in regular kernels, since
the kernel-yocto bits aren't generally useful (yet)
- user_features class: easier user manipulation of DISTRO_FEATURES from
local.conf
- buildstats-summary class: using buildstats, show a summary at the end
of the build showing how many recips ran do_populate_sysroot vs
do_populate_sysroot_setscene
- deploy-license-manifest class: this is fairly self explanatory. it deploys
the manifest generated by license.bbclass into DEPLOY_DIR via an
IMAGE_POSTPROCESS_COMMAND, and also runs a sed script which produces a
CSV version of the manifest in DEPLOY_DIR also
- kernel-lttng - automatically enable the kernel options needed to support
lttng in any non-linux-yocto kernel
- mirrors class: a much simplified, compact version of the upstream
default mirrors, without location-specific mirrors, and with more use of
regex to reduce the number of entries
- sstate-reuse class: this should be renamed, but it provides a
convenient mechanism to automatically check sstate mirrors in both the
default sstate extra path, as well as specified fallback hosts for
native recipes, and finally falls back to a flat layout. this means that
a mirror can be populated with native sstate archives in a
RedHatEnterprise-5 directory, and knowing we can run binaries from that
host, it will check there on the mirror. Example:
SSTATE_MIRROR_DISTROS += "RedHatEnterprise-5"
SSTATE_MIRROR_SITES += "file:///cache/sstate http://my.server/sstate-cache"
- isolated-sstate-dir class: link any used shared state archives into an
isolated sstate directory, so we can distinguish between the contents of
SSTATE_DIR and the sstate archives actually used for the build. This is
needed by our release process.
- package_early_expand class: work around self referential variable bug
with SUMMARY and DESCRIPTION. Multiple packaging classes add a package
name override, then getVar('SUMMARY', True). Yet the default values of
SUMMARY_${PN}-dbg and friends refer to '${SUMMARY}'. So first
SUMMARY_${PN}-dbg replaces SUMMARY, then SUMMARY is referring to itself.
This class forces early expansion of the SUMMARY and DESCRIPTION
variables to work around the issue. A proper fix would likely be to stop
using package name OVERRIDES in the packaging classes.
To push upstream next
=====================
- blktrace
- libpcre
- newt
- perf
- samba
- tar
- wireless-tools
- `package_{ipk,rpm}`: avoid matching a pattern against `TARGET_OS`
regarding the locale installation. It's not necessary, as the uclibc
.conf files already handle this.
DSO Link Change
===============
- shared-mime-info
- wpa-supplicant
Parallel make / install
=======================
- gettext
- libtool
- lttng2-ust
- openssh
Lttng
=====
- liburcu: patched for mips
- lttng2-ust, lttng-{ust,tools,modules}:
adjusted COMPATIBLE_HOST due to liburcu being patched for mips
patches for improved tracing for MESA, etc
- various kernel bbappends: improved tracing
Misc
====
- busybox: dep on meta-oe's fbset-modes if CONFIG_FBSET=y
- binutils-libs, oprofile: add and use more minimal binutils recipe for
oprofile. This recipe just builds libbfd and
libiberty
- libffi: patches for mips o32/n32
- boot-format: use a different repo with additional files
- udev: retained 164 recipe for machines that still need it
