[dpdk-dev] [PATCH 1/2] examples/distributor: Fix compile issue

[Michael Qiu]

examples/distributor/main.c(338): error #167:
argument of type "struct rte_mbuf *"
is incompatible with parameter of type "const char *"
  			_mm_prefetch(bufs[0], 0);

The first param of _mm_prefetch should be "const char *" and
need convert "struct rte_mbuf *" to "const void *".

[dpdk-dev] [PATCH 2/2] Fix compile issue in i686 platform

[Michael Qiu]

In i686 platform, long is 32bit, so XXX_CYCLECOUNTER_MASK
need define as 'ULL'

Hi Michael,
Thank you very much for working on compilation issues.
Please could you try to insert a "Fixes:" line in your logs?

This patch is correct but the description is not exact:
I have no issue with my i686 compiler.
For future reference, please could you be more precise
about the reproduction environment? Is it related to a specific compiler?

We also need to add these lines:
Fixes: 9c857bf6be87 ("igb: support ieee1588 functions for device time")
Fixes: 1c4445e1f28e ("ixgbe: support ieee1588 functions for device time")

Re: [dpdk-dev] [PATCH 1/2] examples/distributor: Fix compile issue

OK, I will be for careful about the compile and os next time.

So I will repost the patch set.

Michael, it is the same comment as the first patch.
How your compiler is different of mine which compiles fine without this patch?
I'm using GCC 5.2.0.
