[dpdk-dev] [PATCH 00/15] Build fixes for musl libc

[Natanael Copa]

A set of patches to fix build with musl libc. I also did a few cleanups wrt
macros and fixed a few scary compiler warnings while at it.

Please note that those are only compile tested on x86_64 with musl libc.

Natanael Copa (15):
  app/testpmd: replace uint with unsigned int
  net/cxgbe: replace uint with unsigned int
  bus/pci: add fallback for out[lwb]_p for non GNU libc
  bus/pci: factor out various ifdefs in pci_uio_ioport_{read,write}
  bus/fslmc: fix compile error with musl libc
  bus/fslmc: remove unused include of error.h
  net/nfp: build fix for musl libc
  app/test: include fcntl.h due to use of O_RDONLY
  app/test: fix setting of -D_GNU_SOURCE with meson
  bus/dpaa: use warn(3) instead of error(3) to improve portability
  bus/dpaa: fix warning: "__WORDSIZE" is not defined, evaluates to 0
  crypto/dpaa2_sec: build fix for musl libc
  crypto/dpaa2_sec: simplify pr_{debug,err,warn} macros
  net/netvsc: fix compile warning for fcntl.h include
  eal/linux: use gettid(2) for debug message in sigbus_handler

[dpdk-dev] [PATCH 03/15] bus/pci: add fallback for out[lwb]_p 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 ifixes 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'

Hi Natanael,

Thank you for the patches.
I can see you have sent v2 for some of the individual patches in your set, it is
too hard to maintain individual patches in a set, also it breaks automated
checks and patchwork patchset logic.
Can you please send whole patchset when you need to update patches, starting
with a v3 of latest patchset?

Thanks,
ferruh

I actually thought recent version of patchwork could handle that. Sorry.

A full patchset was resent.

[dpdk-dev] [PATCH 09/15] app/test: fix setting of -D_GNU_SOURCE with meson

[Natanael Copa]

in app/test/meson.build the default_cflag is never used so the
-D_GNU_SOURCE was never passed as intended.

Fixes the following build error with musl libc:

../lib/librte_eal/common/include/rte_lcore.h:26:9: error: unknown type name 'cpu_set_t'

The problem is that cpu_set_t is only defined when _GNU_SOURCE is set.

Note that err.h is not in POSIX standard either, but is implemented in musl

[dpdk-dev] [PATCH 11/15] bus/dpaa: fix warning: "__WORDSIZE" is not defined, evaluates to 0

[Natanael Copa]

There is no standard saying that __WORDSIZE should be be defined or in
what include it should be defined. Use a portable way to detect 64 bit
environment.

This fixes a warning when building with musl libc:

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

Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>

This was not really a compile error but the warning looked scary enough.

There are various alternative ways to detect 64bit user-space at compile time,
but this is the most portable way I think.

[dpdk-dev] [PATCH 15/15] eal/linux: use gettid(2) for debug message in sigbus_handler

[Natanael Copa]

There is no guarantee that pthread_self() returns the thread id or that
pthread_t is an integer. Use gettid(2) to get the kernel thread id
instead.

This fixes the following warning when building with musl libc:

../lib/librte_eal/linuxapp/eal/eal_dev.c: In function 'sigbus_handler':
../lib/librte_eal/linuxapp/eal/eal_dev.c:70:3: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
   (int)pthread_self(), info->si_addr);
   ^

This is not reallly a compile error, but the warning looked a bit scary, and
code looked wrong, so I fixed it.

I though glibc didn't want to expose thread id.

Personally, I would just drop the thread from the log message since it is
not that useful anyway.

[dpdk-dev] [PATCH v2 15/15] eal/linux: simplify debug message in sigbus_handler

[Natanael Copa]

There is no guarantee that pthread_self() returns the thread ID or that
pthread_t is an integer. The thread ID is not that useful so simply
remove it.

This fixes the following warning when building with musl libc:

../lib/librte_eal/linuxapp/eal/eal_dev.c: In function 'sigbus_handler':
../lib/librte_eal/linuxapp/eal/eal_dev.c:70:3: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
   (int)pthread_self(), info->si_addr);
   ^

v1 -> v2: remove gettid() and remove thread id from debug message.

argp is a GNU extension and in Alpine we have it as a separate addon
package. Try `apk add argp-standalone`.

I also had to unset the RTE_BACKTRACE when building with ninja.
