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.

2019-03-12Use AVX2 as default even on AVX512 systemsDamjan Marion1-1/+1
Use of scalar AVX512 instructions impacts the maximum CPU frequency as they require CPU to request level 1 power license. So sparse use of AVX512 like we do, typically causes more harm than improvement.

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>

2018-12-05Improve strncpy_s src/dst overlap checkDave Barach1-2/+12
Let m = user estimate of the (max) src string length, low = smaller address of (src, dst), hi = larger address (src, dst). if (low + (m - 1) >= hi), we have a *potential* overlapping copy which is not allowed. Before we declare overlap - and return an error - retry the check with m = actual src string length. The resulting "test string" failure affected aarch64 (only) because of differences in test code stack variable placement / alignment.

2018-12-02vppinfra: c11 safe string functionsSteven2-0/+1082
Add memcmp_s, strcmp_s, strncmp_s, strcpy_s, strncpy_s, strcat_s, strncat_s, strtok_s, strnlen_s, and strstr_s C11 safe string API. For migrating extant unsafe API, add also the corresponding macro version of each safe API, clib_memcmp, clib_strcmp, etc. In general, the benefits of the safe string APIs are to provide null pointer checks, add additional argument to specify the string length of the passed string rather than relying on the null terminated character, and src/dest overlap checking for the the string copy operations. The macro version of the API takes the same number of arguments as the unsafe API to provide easy migration. However, it does not usually provide the full aformentioned benefits. In some cases, it is necessary to move to the safe API rather than using the macro in order to avoid some unpredictable problems such as accessing memory beyond what it is intended due to the lack of the passed string length. dbarach: add a "make test" vector, and a doxygen file header cookie.
