2020-10-06vppinfra: add heap header in front of dlmalloc spaceDamjan Marion1-0/+2
This patch adds smal header in front of dlmalloc space, and it stores some additional information about the heap. Immediate benefit of this patch is that we know the underlying page size si we can display heap page statistics / real memory usage.

2020-04-21vppinfra: bihash improvementsDave Barach1-0/+32
Template instances can allocate BIHASH_KVP_PER_PAGE data records tangent to the bucket, to remove a dependent read / prefetch. Template instances can ask for immediate memory allocation, to avoid several branches in the lookup path. Clean up l2 fib, gpb plugin codes: use clib_bihash_get_bucket(...) Use hugepages for bihash allocation arenas Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Damjan Marion <damarion@cisco.com> Change-Id: I92fc11bc58e48d84e2d61f44580916dd1c56361c

2019-01-01Default huge page size to the regular page sizeDave Barach1-0/+6
With this simple tweak, vpp is OK for "make test" or non-dpdk driver operation over a kernel which doesn't support hugepages at all. Tested on a Raspberry-pi 3B+ running the Ubuntu 18.04 64-bit server beta image. It's amazing that such a minimal system will not only self-compile vpp, but also run the unit tests. It's slow, but what do you expect for that amount of money? Change-Id: I7f080f871c828cc4b44be13809495278fadbd717 Signed-off-by: Dave Barach <dave@barachs.net>

2017-09-18Fixes for issues Coverity has reported (VPP-972)Chris Luke1-1/+1
177117: fstat() returns -1 on error; the code is checking for any positive value instead 175142: final return could never be reached; simple refactoring 175235,175236: Warning suppressed with an explicit cast to (void) 174817: Final return couldn't be reached; is is_in_order is 0 then 'rv' is already returned above 172095,172093: If is_is_set does not get set to 1, then return 0 has already been invoked 174405: Re-kill this (nothing sets rv) 171136: Looks like a cmd line flag to set test_bytes was missing; added it, and refactored the argc/argv processing to avoid two other potential segv's 176813: Add range checking for term width/height. First stab at a reasonable range is 1-512 for both. 175350: Fix implicit casting in shift operation 174272: Not a c+p error; try using a coverity annotation to ignore it 174273,175320: Annotated FORWARD_NULL Change-Id: I58d0f860fc2209f59f8d1b6b344d631b8d429ace Signed-off-by: Chris Luke <chrisy@flirble.org>
