[igt-dev] [PATCH i-g-t v2 0/4] Use C11 atomics

[igt-dev] [PATCH i-g-t v2 0/4] Use C11 atomics

[Guillaume Tucker]

This series replaces calls to the __sync_* functions with the more
recent atomic_* ones defined in stdatomic.h in gem_create and
sw_sync.  It also adds dependency on libatomic when required, that is
to say when the CPU architecture doesn't provide native support for
some atomic operations.  This makes the tests more portable, in
particular for 32-bit MIPS which doesn't support 64-bit atomics.

v2:
 - add linker test to only add dependency on libatomic when needed
 - only add libatomic dependency to gem_create and sw_sync
 - use stdatomic.h and _Atomic type modifier
 - explicitly require libatomic in all Docker images

[Intel-gfx] [PATCH i-g-t v2 1/4] meson: add libatomic dependency

[Guillaume Tucker]

Add conditional dependency on libatomic in order to be able to use the
__atomic_* functions instead of the older __sync_* ones.  The
libatomic library is only needed when there aren't any native support
on the current architecture, so a linker test is used for this
purpose.  This enables atomic operations to be on a wider number of
architectures including MIPS.

Minor: maybe we could've used stdatomic.h's atomic_* functions (without
the "__" prefix) for consistency with the actual IGT code?

We could use null_dep instead, to make it consistent with the other
branch.

I actually thought it was more correct to use the __atomic_*
functions directly from the libatomic library as this is a linker
test.  If for any reason stdatomic.h changes between versions or
compilers and uses something else than libatomic, then this test
would become invalid.

Ack, will fix that in v3.

I don't know whether __atomic_* functions are standard builtins or if
they are just an implementation detail.

If they are standard builtins, it makes more sense to check for them as
this patch does.

If they aren't, we instead should try to link a program using
stdatomic.h's atomic_* functions, and if it doesn't work assume
libatomic.so is required.

[igt-dev] [PATCH i-g-t v2 2/4] gitlab-ci: add libatomic to docker images

[Guillaume Tucker]

Add libatomic to the Fedora docker image so it can link binaries that
use __atomic_* functions.  Also explicitly add libatomic1 to Debian
docker images even though it's already installed as a dependency.

libatomic1 is the runtime lib, for linking you need the package that
contains libatomic.so. That is *quick search*
libgcc-$version-dev. There doesn't seem to be a generic metapackage
for "the latest libgcc-dev", other than... 'gcc'.

Since Debian is acting a bit speshul here I'd just drop the explicit
libatomic installation.

Possibly the same comment on fedora but I'm not aware of how they
split their gcc package. Anyway, the file to check for is
'libatomic.so'.

Hmm, I see the .so in libatomic1…

So, I've dropped the libatomic1 as it's indeed not required
*except* that it is for non-x86 architectures at run-time with
multi-arch file systems.  I found that when adding ci tests for
mips, as of course it then needs it when running gem_create.  I'm
sending a v3 with this.

Thanks,
Guillaume

[igt-dev] [PATCH i-g-t v2 3/4] i915/gem_create: use atomic_* instead of __sync_*

[Guillaume Tucker]

This fixes builds on some architectures, in particular MIPS which
doesn't have __sync_add_and_fetch_8 and __sync_val_compare_and_swap_8
for 64-bit variable handling.

* replace calls to the older __sync_* functions with the new atomic_*
  standard ones
* use the _Atomic type modifier as required with stdatomic.h functions
* add dependency for gem_create on libatomic

[Intel-gfx] [PATCH i-g-t v2 4/4] tests/sw_sync: use atomic_* instead of __sync_*

[Guillaume Tucker]

Replace calls to the older __sync_* functions with the new atomic_*
standard ones to be consistent with other tests and improve
portability across CPU architectures.  Add dependency of sw_sync on
libatomic.
