[PATCH v2 0/5] external-arm-toolchain: Add support for SDK generation

[PATCH v2 0/5] external-arm-toolchain: Add support for SDK generation

[Sumit Garg]

Patch #1 #2 and #3 adds impprovements in external-arm-toolchain recipe in order
to support SDK generation. SDK generation has been tested using:

$ bitbake core-image-base -c populate_sdk

Currently generated SDK only uses glibc provided by pre-built toolchain. The
cross compiler, binutils, gdb/gdbserver etc. are built from source. This is
something we would like to improve in future to package most of the components
from pre-built toolchain instead.

Generated SDK has been tested using testsdk as follows:

$ bitbake core-image-base -c testsdk

Results:

SDK testing environment: aarch64-poky-linux
GalculatorTest class: SDK doesn't contain gettext
No python package in the SDK

core-image-base sdk - OK - All required tests passed (successes=10, skipped=2, failures=0, errors=0)

Patch #4 adds a README for meta-arm-toolchain layer.

Patch #5 adds package specific licences for external-arm-toolchain recipe.

Changes in v2:
- Adds a new patch #3 which fixes issues reported by testsdk.
- Define FILES_${PN}-dev from scratch which additionally refines packaging
  for dev headers as well.
- Make README common for whole meta-arm-toolchain layer rather than specific
  to pre-built toolchain. Add myself as layer maintainer although I would
  be happy to add another co-maintainer if someone is willing to volunteer.
- Update README with testing info for external-arm-toolchain.
- Misc. fixups.

[PATCH v2 1/5] external-arm-toolchain: Remove glibc locale dependency

[Sumit Garg]

Currently external Arm toolchain recipe doesn't provide packages
corresponding to OE glibc locale recipe. So explicitly remove corresponding
libc dependencies until we sort out glibc locale packaging rather than
blocking OE SDK generation which is still useful without glibc locale
packaging.

I guess we can merge this one for now with the idea of getting back to it 
later and trying to properly package gconv libs and locales.

BTW, avoiding _remove would require adding intermediary variable to OE-Core 
just for this sub-list in order to clear it out downstream...

[PATCH v2 2/5] external-arm-toolchain: Refine dev libraries/headers packaging

[Sumit Garg]

OE core by default package all libraries/headers installed as
"${libdir}/lib*.so", "${libdir}/*.la" and {includedir} as part of
FILES_${PN}-dev" but in case of external Arm toolchain recipe, multiple
packages are provided which needs to include specific libraries and
headers. So define "FILES_${PN}-dev" from scratch in order to package
dev libraries/headers as part of intended packages and only package
remaining libraries/headers as part of "FILES_${PN}-dev".

This is probably fine, but have you considered/tried re-ordering list of 
PACKAGES, moving ${PN}-dev to the end? That way it would let other packages 
to pick up their files before collecting the remainder. Not sure, but I wonder 
if that would be any cleaner...

Your suggestion sounded useful, so I gave it a try but unfortunately
OE core still prefers to package libraries and headers as part of
"FILES_${PN}-dev" rather than other intended packages.

Sorry, I may not have been very clear. I didn't mean moving FILES_${PN}-dev 
position in the recipe, but rather ${PN}-dev position inside PACKAGES list.

So, if you have FILES_a = "*" and FILES_b = "*" it all depends on which one is 
listed first in PACKAGES to get all the files: PACKAGES = "a b" or "b a"

This have happened in the past few times, e.g this one is very clear to 
illustrate the point:

http://arago-project.org/git/?p=meta-arago.git;a=commitdiff;h=fd2587171fec09ffb2974fc7b402ae6daf9ebaea

In that case, libgcc-dev had to be moved to the very front of the list to get 
a chance to pick up the file, which would otherwise go into another package.

But then, immediate expansion (as _remove wasn't available back then) or the 
use of actual _remove maybe fine for downstream, but otherwise is discouraged. 

So, if nothing else works, just re-defining FILES_${PN}-dev should be fine.

Sorry I misinterpreted about what you meant. This approach worked like
a charm and it's much cleaner I think. So I just did following change
instead of this patch:

If this change looks fine, then I will use it instead for v3.

[PATCH v2 3/5] external-arm-toolchain: Align glibc packaging to OE TARGET_SYS

[Sumit Garg]

OE native and cross compilers (in case of SDK) uses OE TARGET_SYS to
create standard paths to search for libraries and headers during
compilation.

Currently external-arm-toolchain recipe temporarily override TARGET_SYS
with EAT_TARGET_SYS and packages libraries and headers corresponding to
EAT_TARGET_SYS which leads to failures during native and cross compilation
(in case of SDK) such as:

$ $CXX -o hello++ hello.cpp
In file included from hello.cpp:1:
/tmp/armsdk/sysroots/armv7at2hf-neon-oe-linux-gnueabi/usr/include/c++/9.2.1/iostream:38:10: fatal error: bits/c++config.h: No such file or directory
   38 | #include <bits/c++config.h>
      |          ^~~~~~~~~~~~~~~~~~
compilation terminated.

$ $CC hello.c
real-ld: cannot find crtbeginS.o: No such file or directory

So remove temp override of TARGET_SYS and rather package libraries and
headers corresponding to OE TARGET_SYS.

This fixes changes added in commit:
https://git.linaro.org/openembedded/meta-linaro.git/commit/?id=91ea4d017bf0598e49944e76c889e66d58c066ce

Also, update location for unwind.h gcc-arm-common.inc accordingly.

Yeah, I tried this before some time ago... It didn't work for me for all the 
use cases. It works for you for SDK because you build an OE compiler from 
sources for that case. If you try to use EAT (external ARM toolchain) with OE 
SDK, it would fail.

TARGET_SYS != EAT_TARGET_SYS is indeed inconvenient, but has been there for 
long time. There are other assumptions and limitations in some places of OE 
and those are not restricted to external-arm-toolchain, e.g. you can see 
similar workarounds for musl toolchain:

/usr/lib:
arm-oe-linux-musleabi/
arm-oe-linux-gnueabi -> arm-oe-linux-musleabi
arm-oe-linux-musleabihf -> arm-oe-linux-musleabi

Similar to that, I've been fixing it in many places like:

/usr/lib:
arm-linux-gnueabihf/
arm-linux-gnueabi -> arm-linux-gnueabihf

/usr/include/c++/<version>/:
arm-linux-gnueabihf/
arm-linux-gnueabi -> arm-linux-gnueabihf

BTW, arm-linux-gnueabihf is EAT gcc8, EAT gcc9 uses arm-none-linux-gnueabihf:

/usr/lib:
arm-none-linux-gnueabihf/
arm-linux-gnueabi -> arm-none-linux-gnueabihf

So, using such symlinks allows both OE compiler and EAT cross-compiler to find 
runtime libraries and headers correctly, both on-target and in SDK sysroot.

So, in general, I would welcome this simplification if TARGET_SYS was the same 
as EAT_TARGET_SYS, but I don't believe it's that easy to pull it off...

Agree, I guess this is one of your downstream use-case which is
something we would like to be supported in upstream as well in future.

Makes sense, will add symlinks for EAT_TARGET_SYS in order to continue
supporting your downstream use-cases.

Yeah, this is the first thing I did to override TARGET_SYS with
EAT_TARGET_SYS but it led to OE recipes to fail.

You don't have to do everything by yourself - I'm more than happy to

+meta-arm-toolchain Yocto Layer
+==============================
+
+This layer contains recipes for GNU Arm toolchains which could either be built
+from source or pre-built toolchain binaries.
+
+Information regarding contributing, reporting bugs, etc can be found in the
+top-level meta-arm readme file.
+
+Source Arm toolchain for Linux development
+------------------------------------------
+
+Recipes for GNU Arm toolchain built from source are provided under
+``recipes-devtools/gcc/``. In order to use Arm toolchain instead of OE core
+toolchain, one just needs to override ``GCCVERSION`` in corresponding distro
+conf file.
+
+-  Eg. to use GNU Arm toolchain version ``9.2``
+   GCCVERSION = "arm-9.2"
+
+Pre-built Arm toolchain for Linux development
+---------------------------------------------
+
+Recipes for pre-built GNU Arm toolchain for Linux development are provided under
+``recipes-devtools/external-arm-toolchain/``.
+
+external-arm-toolchain.bb
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This recipe provides support for pre-built GNU toolchains targeting processors
+from the Arm Cortex-A family and implementing the Arm A-profile architecture.
+
+Usage
+^^^^^
+
+In order to use any of pre-built Arm toolchain versions (8.2, 8.3, 9.2 and so
+on), a user needs to download and untar tool-set on host machine at a particular
+installation path eg: ``/opt/toolchain/``. Then user needs to specify following
+in ``conf/local.conf`` in order to replace OE toolchain with pre-built GNU-A
+toolchain:
+
+TCMODE = "external-arm"
+EXTERNAL_TOOLCHAIN = "<path-to-the-toolchain>"
+
+-  Eg. for AArch64 (eg. qemuarm64 machine in poky distro)
+   EXTERNAL_TOOLCHAIN = "\
+     <installation-path>/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu \
+   "
+
+-  Eg. for AArch32 (eg. qemuarm machine in poky distro)
+   EXTERNAL_TOOLCHAIN = "\
+     <installation-path>/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf \
+   "
+
+Supported distros and machines
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Since this pre-built GNU-A tool-set simply replaces OE toolchain, so it is
+meant to be distro and machine agnostic as long as one is cross-compiling for
+Arm A-profile architecture.
+
+Tested distro and machines (for zeus stable release):
+1.  Distro: poky; machines: qemuarm and qemuarm64 (build and boot tested)
+2.  Distro: RPB; machines: dragonboard-410c (build and boot tested)
+3.  Distro: world; machines: qemuarm and qemuarm64. Build tested for following
+    layers:
+    - poky/meta
+    - poky/meta-poky
+    - poky/meta-yocto-bsp
+    - meta-openembedded/meta-oe
+    - meta-openembedded/meta-python
+    - meta-openembedded/meta-networking
+
+SDK support
+^^^^^^^^^^^
+
+Pre-built toochain provides support to build OE SDK which has been tested using
+following commands:
+
+$ bitbake core-image-base -c populate_sdk
+$ bitbake core-image-base -c testsdk
+
+Note: Currently generated SDK only uses glibc provided by pre-built toolchain.
+      The cross compiler, binutils, gdb/gdbserver etc. are built from source.
+      This is something we would like to improve in future in order to package
+      most of the components from pre-built toolchain instead.
+
+Pre-built Arm toolchain for bare-metal development
+--------------------------------------------------
+
+Recipes for pre-built GNU Arm toolchain for bare-metal development are provided
+under ``recipes-devtools/external-arm-toolchain/``.
+
+gcc-arm-none-eabi_<version>.bb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This recipe provides support for pre-built GNU Arm Embedded toolchain for
+bare-metal software development on devices based on 32-bit Arm Cortex-A,
+Cortex-R and Cortex-M processors.
+
+Supported version: 9-2019-q4-major
+
+gcc-aarch64-none-elf_<version>.bb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This recipe provides support for pre-built GNU Arm toolchain for bare-metal
+software development on devices based on 64-bit Arm Cortex-A processors.
+
+Supported version: 9.2-2019.12
