From 299571aca34d36e637e43cfbba6275662d0d7795 Mon Sep 17 00:00:00 2001 From: Damjan Marion Date: Sat, 19 Mar 2022 00:07:52 +0100 Subject: vppinfra: vector allocator rework - support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion --- src/vppinfra/types.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'src/vppinfra/types.h') diff --git a/src/vppinfra/types.h b/src/vppinfra/types.h index 24dd5b30e02..e098db5fbaf 100644 --- a/src/vppinfra/types.h +++ b/src/vppinfra/types.h @@ -135,6 +135,14 @@ pointer_to_uword (const void *p) return (uword) (clib_address_t) p; } +static inline __attribute__ ((always_inline)) uword +pointer_is_aligned (void *p, uword align) +{ + if ((pointer_to_uword (p) & (align - 1)) == 0) + return 1; + return 0; +} + #define uword_to_pointer(u,type) ((type) (clib_address_t) (u)) /* Any type: can be either word or pointer. */ -- cgit 1.2.3-korg
