Anton, All,

On 2014-08-08 19:09 +0400, Anton Kolesov spake thusly:
> Pulseaudio requires GCC built-in atomic functions which are architecture specific
> and may not be implemented.
> 
> This fixes:

You forgot espeak's pulseaudio backen option:

    config BR2_PACKAGE_ESPEAK_AUDIO_BACKEND_PULSEAUDIO
        select BR2_PACKAGE_PULSEAUDIO

which should also depend on intrinsics.

Regards,
Yann E. MORIN.

I'd prefer we keep the same title for comment and options, such as:

    comment "FT2xxx/FT4xxx support needs a toolchain w/ atomic intrinsics"

This can be fixed by whoever commits that, I guess no need to resend.

Well, this patch does a bit more than that: it replaces the dependency
on !ARC with the new generic dependency.

What about enhancing the commit log as thus, for example:

    Msgpack requires GCC built-in atomic functions which are
    architecture specific and may not be implemented.

    Replace the current dependency on !ARC (which was the sole
    architecture so far to not have intrinsics), to the generic
    _HAS_ATOMIC_INTRINSICS dependency.

Otherwise:

However, a small comment, unrelated to your change...

This should also 'select BR2_PACKAGE_CAIRO' but that's not the fault of

I'll send a fix for that shortly.

[Buildroot] [PATCH 1/9] arc: Support option of atomic extension

[Anton Kolesov]

GCC has several builtin functions that implement atomic operations. In GCC
for ARC those functions rely on LLOCK/SCOND instructions which are optional
in ARC CPU's. If software uses those functions and as a result those
instructions, it will be abort with Illegal instruction exception. To avoid
confusion user should first specify that their CPU supports atomic
extension, which will allow selection of packages that use builtin atomic
functions.

I think this is looking generally good, but after discussing with Yann,
I think we'd prefer to have a slightly more generic solution. First, a
hidden kconfig boolean that tells whether the compiler has the atomic
intrinsics:

config BR2_TOOLCHAIN_HAS_ATOMIC_INTRINSICS
	bool

and then architectures would "select" this hidden boolean whenever they
have the atomic intrinsics, and packages would use this hidden boolean
to create the dependencies.

What do you think about this? It's not a big change compared to what
you have done, it only pushes things to be a little bit more generic.

Thanks!

Thomas

[Buildroot] [PATCH v2 1/9] toolchain: Add config option for atomic intrinsics

[Anton Kolesov]

GCC has several builtin functions that implement atomic operations. Those
functions are architecture specific and may not be implemented by the
specific toolchain. In case of GCC for ARC those functions rely on
LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't
support those instructions but software tries to use them, then application
will be aborted with Illegal instruction exception. To avoid confusion user
should first specify that their CPU supports atomic extension, which will
allow selection of packages that use builtin atomic functions.

[Buildroot] [PATCH v2 1/9] toolchain: Add config option for atomic intrinsics

[Yann E. MORIN]

Anton, All,

On 2014-07-31 17:24 +0400, Anton Kolesov spake thusly:
> GCC has several builtin functions that implement atomic operations. Those
> functions are architecture specific and may not be implemented by the
> specific toolchain. In case of GCC for ARC those functions rely on
> LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't

> will be aborted with Illegal instruction exception. To avoid confusion user
> should first specify that their CPU supports atomic extension, which will
> allow selection of packages that use builtin atomic functions.

I think what Thomas and I discussed, was to have a patch series that
does the following changes:

   1- introduce BR2_TOOLCHAIN_HAS_ATOMIC_INTRINSICS;
   2- have all current architectures, that have atomics, select that new
      symbol (note: i386 does not, i486 and above have, for example);
   3- convert packages (one patch par package) to depend on it;
   4- introduce BR2_ARC_ATOMIC_EXT that selects it, too.

This is more logical: you first add a new option, and then you gradually
start using it, until finally you airrive to what you eventually wanted.

Regards,
Yann E. MORIN.

Well, that's pretty much what Anton did actually: his patch 1 covers
your items (1), (2) and (4), and his other patches cover your item (3).
And there's actually no problem in having (4) being done before (3).

So far the only difference between what you expose and what he has done
is the fact that his patch series have
BR2_TOOLCHAIN_HAS_ATOMIC_INTRINSICS selected even for i386. But the
current Buildroot already assumes that i386 has atomic intrinsics.

I have applied the following patches from your series:

3ebdc64dcc687a95dd4fed7eda8ff811d2db0eaf thrift: Add dependency on atomic intrinsics
b6f9dd2a389c1f4da858c928bf48f8baec461082 libtorrent: Add dependency on atomic intrinsics
b7a791a103d21835d0e3fb8accfb58346330560f icu: Add dependency on atomic intrinsics
b35d1582346625a7076de0a44958d5c5133103d2 jack2: Add dependency on atomic intrinsics
cbffd50561f7ce595296bddaf108031e501b2063 toolchain: Add config option for atomic intrinsics

I did not apply the other patches, because they were missing the
propagation of the atomic intrinsics dependency to the reverse
depencies of the package needing atomic intrinsics. For example, in
PATCH 2/9, you add the dependency on atomic intrinsics to Cairo, but
nowhere you propagate that to the reverse dependencies of Cairo. Could
you send an updated version of those patches, taking into account this
need?

Also, could you send a patch against the Buildroot manual that
documents the atomic intrinsics dependency, like we document
dependencies like wchar, largefile, ipv6 and so on.

Thanks!

Thomas

[Buildroot] [PATCH v3 1/4] cairo: Add dependency on atomic intrinsics

[Anton Kolesov]

Cairo requires GCC built-in atomic functions which are architecture specific
and may not be implemented.

[Buildroot] [PATCH v3 4/4] msgpack: Add dependency on atomic intrinsics

[Anton Kolesov]

Msgpack requires GCC built-in atomic functions which are architecture specific
and may not be implemented.

This fixes:

Actually, the more I think about this, and the more I believe it should
be a property of the architecture rather than a property of the
toolchain. So it should probably rather be
BR2_ARCH_HAS_ATOMIC_INTRINSICS. And then, since it's a property of the
architecture, i.e not something the user can enable/disable, there is
no point in adding Config.in comment for that. So we would handle that
like we handle BR2_USE_MMU, not like we handle BR2_LARGEFILE.

Thoughts?

Ah, I remember now, that we talked about that. My bad, I had forgotten
during the review.

However, we can't really change the implementation now, we're frozen for
the release.

What about adding this to the manual for now, since it does reflect the
current status of the code, and switch to an architecture option in
-next, or after the release is cut?

Regards,
Yann E. MORIN.
