Vision
Incorporate toolchain components and other bits (binutils, gcc, glibc, gdb, kernel, linux-libc-headers) into a meta-x32 layer; And added needed infrastructure into the oe-core/yocto tree so that meta-x32 layer can work on top; so that one can build complete images with x32 abi binaries.
Status
- The meta-x32 layer is hosting the x32 tollchain recipes now
- core-image-sato can build and run under qemu
- Many recipes have been fixed for compilation with x32 toolchain.
X32 poky setup
- add meta-x32 layer - For Edison and Denzil, this is not need for 1.3
- git clone x32 layer
git clone git://git.yoctoproject.org/experimental/meta-x32
- cat conf/bblayers.conf
# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf # changes incompatibly LCONF_VERSION = "4" BBFILES ?= "" BBLAYERS = " \ /home/nitin/prj/poky.git/meta \ /home/nitin/prj/poky.git/meta-yocto \ /home/nitin/prj/meta-x32.git \ "
- And add these lines to local.conf - for all releases
MACHINE = "qemux86-64"
DEFAULTTUNE = "x86-64-x32"
#MACHINE = "atom-pc"
#DEFAULTTUNE = "core2-64-x32"
baselib = "${@d.getVar('BASE_LIB_tune-' + (d.getVar('DEFAULTTUNE', True) or 'INVALID'), True) or 'lib'}"
Tasks
- try and find some way of assessing performance
