[Buildroot] [PATCH v2 00/14] Another set of Bootlin toolchain integration improvements

[Thomas Petazzoni via buildroot]

Hello,

Overall summary
===============

Patches 1 to 12 in this series are fixes for autobuilder
issues. Patches 13 and 14 are improvements.

Patches 1 and 2 fix the issue of RISC-V 64-bit toolchains being
available on MMU-less architectures, even though they are not
supported by the toolchain.

Patches 3 and 4 fix the issue of ARM little endian toolchains being
selectable for ARM big endian architectures.

Patches 5 and 6 fix the issue of i686 toolchains being used for < i686
platforms.

Patches 7, 8 and 9 fix the issue of an error when trying to copy
gdbserver, with toolchains that don't have gdbserver.

Patches 10, 11 and 12 fix the issue of the "mips64" Bootlin toolchains
being obsolete, but the gen-bootlin-toolchains still thinking they
were available. This caused some mips64 n64 configurations to be
thought of having Bootlin toolchains available, but in fact no such
toolchains were provided. We fix this by making sure we check if an
architecture has valid toolchains, and erroring out if not. And of
course, we remove the "mips64" toolchain config.

Patches 13 and 14 add support for the ARMv7 big-endian toolchains
provided by toolchains.bootlin.com.

Changes since v1
================

 - Patches 10, 11 and 12 added to fix the "mips64" issue.

[Buildroot] [PATCH v2 01/14] support/scripts/gen-bootlin-toolchains: fix RISC-V 64-bit toolchain description

[Thomas Petazzoni via buildroot]

We now support both MMU-enabled and MMU-less RISC-V 64-bit
configurations. However, the Bootlin toolchain for RISC-V 64-bit only
supports MMU-enabled configurations, but the current logic in
toolchain/toolchain-external/toolchain-external-bootlin/ does not take
this into account, and allows selecting the Booltin toolchain for
MMU-less RISC-V 64-bit configurations.

To fix this, the gen-bootlin-toolchains script is modified to add the
BR2_USE_MMU dependency to the description of the RISC-V 64-bit
toolchain.

However, the BR2_USE_MMU dependency was also added for glibc and musl
toolchains unconditionally, so to avoid duplicating the dependency, we
now only add it only if not already present in the list of
dependencies for this toolchain.

This will allow to fix:

[Buildroot] [PATCH v2 03/14] support/scripts/gen-bootlin-toolchains: improve dependencies of ARM toolchains

[Thomas Petazzoni via buildroot]

The current description of the Bootlin ARM toolchains allows them to
be selected for ARM big endian configurations, which obviously doesn't
work as these Bootlin ARM toolchains are little endian only.

We fix this by adding BR2_arm in the list of conditions for those
toolchains.

Will allow to fix:

[Thomas Petazzoni via buildroot]

This commit regenerates the toolchain-external-bootlin Config.in file
after the ARM toolchain description was modified to make sure they
only match the ARM little endian configurations.

[Buildroot] [PATCH v2 05/14] support/scripts/gen-bootlin-toolchains: adjust dependencies of i686 toolchains

[Thomas Petazzoni via buildroot]

The Bootlin i686 toolchain was already made available only on BR2_i386
with !BR2_x86_i486 && !BR2_x86_i586 && !BR2_x86_1000. However, this
was not sufficient as a few other architecture variants of BR2_i386
are "lower" than i686, and they need to be excluded as well.

Allows to fix:

[Buildroot] [PATCH v2 07/14] toolchain/toolchain-external: add BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER option

[Thomas Petazzoni via buildroot]

Some external toolchains do not have gdbserver available, but the
option BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY is always visible. And
when enabled, this option aborts with an error when gdbserver cannot
be found:

  Could not find gdbserver in external toolchain

Due to that, some random configurations fail to build when
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY=y, for example with the Bootlin
toolchains for Microblaze or OpenRISC (because there's no GDB support
for those architectures).

One solution could be to make "Could not find gdbserver in external
toolchain" a warning instead of a hard error, but then nobody would
notice about this issue, in cases where it should legitimately abort
with a hard error.

So, the clean solution would be to add a
BR2_TOOLCHAIN_EXTERNAL_HAS_GDBSERVER. But that means all existing
external toolchains would have to be modified to select this option.

Instead, and as an exception, we chose to use inverted logic, and
create an option that is the opposite:
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER. By default, we assume
external toolchains have gdbserver. If
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER is enabled, we disallow the
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY option.

Note that the case of custom external toolchain does not matter: by
definition they are not tested by the autobuilders, and by definition,
we cannot now in menuconfig if the custom toolchain has or does not
have gdbserver.

This will help fixing:

Note: if you want me to go with the positive logic option
BR2_TOOLCHAIN_EXTERNAL_HAS_GDBSERVER, I'll be happy to provide the
patches.

[Buildroot] [PATCH v2 10/14] support/scripts/gen-bootlin-toolchains: check that toolchains exists for a certain arch

[Thomas Petazzoni via buildroot]

The "arches" dict lists the architectures for which Bootlin toolchains
are available, along with the corresponding Buildroot conditions for
those architecture variants.

However, there is nothing that checks that such architectures really
have Bootlin toolchains available. Even if no toolchain is available,
the architecture is considered as support, and will be listed in the
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARCH_SUPPORTS option, making menuconfig
believe that some Bootlin toolchain is available for the selected
architecture variant.

This is currently the case with the "mips64" architecture (as
identified by the Bootlin toolchains project). Such toolchains have
been made obsolete in toolchains.bootlin.com and replaced by the
mips64-n32 toolchains. But "mips64" is still listed in "arches",
causing this architecture to be considered as having Bootlin
toolchains available.

To avoid this to happen in the future, this commit adds a check that
verifies that an architecture listed in "arches" really has at least
one toolchain available.

[Buildroot] [PATCH v2 11/14] support/scripts/gen-bootlin-toolchains: drop "mips64" architecture variant

[Thomas Petazzoni via buildroot]

These toolchains have been marked obsolete by toolchains.bootlin.com
as they are replaced by the mips64-n32 toolchains. See commit:

  https://github.com/bootlin/toolchains-builder/commit/121e78806b4968858f22ebea317767883752a456

Will allow to fix:

  This could have been simplified to

	depends on BR2_PACKAGE_GDB_ARCH_SUPPORTS

but this way is more flexible so better I guess.

Yes, I thought about this (should maybe have written it in the commit
log), but I thought: external toolchains can very well rely on patched
GDB versions that could potentially have support for an architecture
that's not supported in upstream GDB.

I agree this is a corner case, so if we decide that's not worth
considering, I would totally support using
BR2_PACKAGE_GDB_ARCH_SUPPORTS.
