[dpdk-dev] [PATCH 0/7] Enable 32-bit native builds with meson

[Bruce Richardson]

This patchset enables building DPDK on 32-bit systems, and has been tested
using debian 32-bit on x86 i.e. doing an "i686" build in the old build
system.

Additional work is still required (possibly via cross-file) to get DPDK
building for 32-bit on a 64-bit system, but this is the first step in that
process.

[dpdk-dev] [PATCH 5/7] dpaa2: fix default IOVA build setting for meson builds

[Bruce Richardson]

By default, the DPAA2_USE_PHYS_IOVA setting with the make build-system
is "y", which is overridden to "n" in the config file specifically for
the arm64-dpaa2-linuxapp-gcc builds. The lack of this setting in meson
builds causes issues for 32-bit build, as the alternative code paths
have compiler warnings e.g. for i686 builds. Therefore we should align
the meson and make settings, setting the value to "true" by default and
overriding it to "false" for dpaa2-specific builds.

[dpdk-dev] [PATCH 6/7] examples/kni: fix dependency check for building with meson

[Bruce Richardson]

Rather than hard-coding the example app to be built only when a set of
conditions are met, we can simplify things by having the app built when
KNI library itself is available. That saves us duplicating the same set
of restrictions on both library and example app.

[dpdk-dev] [PATCH 7/7] net/avp: fix 32-bit meson builds

[Bruce Richardson]

When compiling with meson, extra warnings are enabled about casting from
integers to different size pointers. This triggers an error in AVP as the
addition of the offset to the pointer address causes the result to be a
64-bit integer which doesn't fit a 32-bit pointer. The fix here is to
explicitly indicate that the offset is of type "uintptr_t" which prevents
any promotion which would cause errors.

[dpdk-dev] [PATCH v2 5/8] dpaa2: fix default IOVA build setting for meson builds

[Bruce Richardson]

By default, the DPAA2_USE_PHYS_IOVA setting with the make build-system
is "y", which is overridden to "n" in the config file specifically for
the arm64-dpaa2-linuxapp-gcc builds. The lack of this setting in meson
builds causes issues for 32-bit build, as the alternative code paths
have compiler warnings e.g. for i686 builds. Therefore we should align
the meson and make settings, setting the value to "true" by default and
overriding it to "false" for dpaa2-specific builds.

Fixes: 6ec78c2463ac ("build: add meson support for dpaaX platforms")

[dpdk-dev] [PATCH v2 6/8] examples/kni: fix dependency check for building with meson

[Bruce Richardson]

Rather than hard-coding the example app to be built only when a set of
conditions are met, we can simplify things by having the app built when
KNI library itself is available. That saves us duplicating the same set
of restrictions on both library and example app.

[dpdk-dev] [PATCH v2 7/8] net/avp: fix 32-bit meson builds

[Bruce Richardson]

When compiling with meson, extra warnings are enabled about casting from
integers to different size pointers. This triggers an error in AVP as the
addition of the offset to the pointer address causes the result to be a
64-bit integer which doesn't fit a 32-bit pointer. The fix here is to
explicitly indicate that the offset is of type "uintptr_t" which prevents
any promotion which would cause errors.
