Signed-off-by: Bill Fischofer <bill.fischofer@linaro.org> --- v3 of this patch incorporates the following changes based on review comments by Petri and Stuart - Remove use of typeof for C99 compliance - Use intmax_t instead of ssize_t for C99 compliance - Move odp_buffer_alloc() and odp_buffer_free() back to odp_buffer_pool.h - Move odp_buffer_pool() to odp_buffer.h - Add @retval white space for .h file readability - Rename odp_config.h packet vars per Petri's preference - Add odp_config.h vars for controlling buffer alignment - Properly support buffer alignment per spec. Supported range is 8 to 4096 v2 of this patch incorporates comments from Bala and Petri. In particular: - buf_size and buf_align in odp_buffer_pool_param_t are now uint32_t - odp_buffer_pool_info_t has been changed to add the shm - odp_buffer_pool_info() has been changed to reflect the above change - odp_config.h adds config vars for default headroom and tailroom - odp_buffer_alloc() and odp_buffer_free() moved to odp_buffer.h - miscellaneous comment improvements and typo corrections example/generator/odp_generator.c | 19 +- example/ipsec/odp_ipsec.c | 57 +- example/l2fwd/odp_l2fwd.c | 19 +- example/odp_example/odp_example.c | 18 +- example/packet/odp_pktio.c | 19 +- example/timer/odp_timer_test.c | 13 +- platform/linux-generic/include/api/odp_buffer.h | 13 +- .../linux-generic/include/api/odp_buffer_pool.h | 117 ++- platform/linux-generic/include/api/odp_config.h | 70 ++ .../linux-generic/include/api/odp_platform_types.h | 12 + .../linux-generic/include/api/odp_shared_memory.h | 10 +- .../linux-generic/include/odp_buffer_inlines.h | 150 ++++ .../linux-generic/include/odp_buffer_internal.h | 152 ++-- .../include/odp_buffer_pool_internal.h | 351 +++++++-- platform/linux-generic/include/odp_internal.h | 2 + .../linux-generic/include/odp_packet_internal.h | 50 +- .../linux-generic/include/odp_timer_internal.h | 11 +- platform/linux-generic/odp_buffer.c | 33 +- platform/linux-generic/odp_buffer_pool.c | 797 +++++++++++---------- platform/linux-generic/odp_linux.c | 4 +- platform/linux-generic/odp_packet.c | 41 +- platform/linux-generic/odp_queue.c | 1 + platform/linux-generic/odp_schedule.c | 20 +- platform/linux-generic/odp_timer.c | 3 +- test/api_test/odp_timer_ping.c | 19 +- test/validation/odp_crypto.c | 43 +- test/validation/odp_queue.c | 19 +- 27 files changed, 1292 insertions(+), 771 deletions(-) create mode 100644 platform/linux-generic/include/odp_buffer_inlines.h
