2019-06-04elog: make elog_string() multi-thread safeSteven Luong1-0/+2
elog is supposed to be thread safe. Yet elog_string() is not. To fulfill that promise, let's make elog_string() thread safe to avoid surprises. Change-Id: Iab82faa7cb6719777a66c3ff14775e59a6a68a20 Signed-off-by: Steven Luong <sluong@cisco.com>

2019-05-17Add a debug-CLI leak-checkerDave Barach1-0/+2
leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-0/+3
Problems Addressed: - Contention of cursize by producer and consumer. - Reduce the no of modulo operations. Changes: - Synchronization between producer and consumer changed from cursize to head and tail indexes Implications: reduces the usable size of fifo by 1. - Using weaker memory ordering C++11 atomics to access head and tail based on producer and consumer role. - Head and tail indexes are unsigned 32 bit integers. Additions and subtraction on them are implicit 32 bit Modulo operation. - Adding weaker memory ordering variants of max_enq, max_deq, is_empty and is_full Using them appropriately in all places. Perfomance improvement (iperf3 via Hoststack): iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86) ~6%(256 rxd/txd) - ~11%(2048 rxd/txd) Change-Id: I1d484e000e437430fdd5a819657d1c6b62443018 Signed-off-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com>

2019-04-02vppinfra: fix sparse_vec_index() returning non-zero index for some ↵Andrew Yourtchenko1-0/+4
nonexistent elements If we are testing for an index whose membership bitmask happens to sit in LSB of uword, and there is nothing else set in that uword in the member bitmask, the shortcut path returning the valid index is taken even if the element with a given index doesn't exist in the sparse vector. This happens because the count of leading zeroes on the value of 0 is zero, which is equal to the value taken modulo bitsize uword. Take care of that case. Also add unittests showing the problem and verifying that sparse_vec_index2 does not have the same issue.

Use of scalar AVX512 instructions impacts the maximum CPU frequency as they require CPU to request level 1 power license.
