Hello DPDK community,
This is the 4th series of the ARMv7 patchset. I've cleaned up
most checkpatch errors:
* Whitespaces were fixed.
* The asm volatile syntax (checkpatch didn't like the named "%xyz"
parameters when listed in the InputOperands list as "[xyz]").
* There are still few complaints (documented in each patch) but
I consider them as unimportant (volatile, couple of line overlaps,
new typedef). If it still can be done better, please report me
your ideas.
Other changes:
* The "introduction patch" was moved to be almost the last patch as
suggested by D. Marchand.
* I've added a note into the release_2_2.rst.
* The RTE_BITMAP_OPTIMIZATIONS was removed.
* The ARMv7 defconfig was renamed as suggested by B. Richardson.
* I've removed the LPM and ACL fixes from the patchset for now.
The libraries table and pipeline are disabled as well.
* The igb_uio driver is disabled.
* The -Wno-error was restricted to cast-align only.
To be answered (from rte_atomic.h patch):
* use __atomic_* or __sync_*? (may affect the required GCC version)
Regards
Jan
