[dpdk-stable] [PATCH v4 1/8] app/testpmd: fix uint build error with musl libc

[Natanael Copa]

Improve portability by avoid use non-standard 'uint'.

Use uint8_t for hash_key_len as rss_key_len is a uint8_t type.

This solves following build error when building with musl libc:

In file included from ../app/test-pmd/cmdline.c:74:
../app/test-pmd/testpmd.h:813:29: error: unknown type name 'uint'; did
you mean 'int'?

      |                             int

Ethdev RSS hash key length is uint8_t, so this patch is correct not using unsigned int as replacement.

[dpdk-stable] [PATCH v4 3/8] bus/pci: add fallback for out* for non GNU libc

[Natanael Copa]

Add a fallback for non-GNU libc systems like musl libc for the
non-standard functions  outl_p, outw_p and outb_p.

This solves the following buildtime errors when building with musl libc:
pci_uio.c:(.text+0xaa1): undefined reference to `outw_p'
pci_uio.c:(.text+0xac5): undefined reference to `outl_p'
pci_uio.c:(.text+0xadf): undefined reference to `outb_p'

We also handle the non-x86 with macros to factor out various ifdefs in
the code.

[dpdk-stable] [PATCH v4 4/8] bus/dpaa: use warn instead of error to improve portability

[Natanael Copa]

Fix build with musl libc by using warn(3) instead of using the GNU
specific error(3).

`error(0, errno, ...)` is identical to `warn(...)` so replace:

  error(0, ret, ...);

with the identical:

  errno = ret;
  warn(...);

We could have used the identical `warnx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant. Avoid the
mess by letting `warn` use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let 'warn' use the proper error message from errno
which is set by kzalloc.

There is no standard saying that __WORDSIZE should be be defined or in
what include it should be defined. Use RTE_ARCH_64 instead.

This solves a warning when building with musl libc:

 warning: "__WORDSIZE" is not defined, evaluates to 0 [-Wundef]

[dpdk-stable] [PATCH v4 6/8] common/dpaax: build fix for musl libc

[Natanael Copa]

The swab16/swab32/swab64 are Linux specific and not GNU libc specific.
Keep the check for __GLIBC__ just in case other GNU systems depends on
this (Hurd or GNU/kFreeBSD).

This fixes a build error with musl libc.
