If I build unmodified dpdk 1.7 (which I can only build for the native platform), it works, however it doesn't work when built with modifications for the default platform, but see below. > I do run acl_autotest with at least 256M of huge-pages as ACL is quite memory consuming and, as I remember, requires at least 2X32M areas of contiguous hugepages. > But in that case (not enough hugepages) it should just fail with something like: > ACL: allocation of 25953152 bytes on socket -1 for ACL_acl_ctx failed > Any other details, so I can try to reproduce it: > arch you build/run it on? x86_64 default build (has to be to test the new code). > amount of free memory in the system? Its an 8G workstation, should have most of that free (haven't checked yet). > Wonder what pstack says? It says that we're stuck in the eal library, before we've touched the ACL library it seems, so I'm not sure whats going on here: #0 0x0000003d11ef53c3 in epoll_wait () from /lib64/libc.so.6 #1 0x00000000004d315a in eal_intr_thread_main () #2 0x0000003d12607f33 in start_thread () from /lib64/libpthread.so.0 #3 0x0000003d11ef4ded in clone () from /lib64/libc.so.6 Thread 2 (Thread 0x7fee73ffe700 (LWP 14529)): #0 0x0000003d1260e87d in read () from /lib64/libpthread.so.0 #1 0x00000000004ced0a in eal_thread_loop () #2 0x0000003d12607f33 in start_thread () from /lib64/libpthread.so.0 #3 0x0000003d11ef4ded in clone () from /lib64/libc.so.6 Thread 1 (Thread 0x7fee84100880 (LWP 14527)): #0 0x000000000041adde in acl_match_check_x2.constprop () #1 0x000000000041b1af in search_sse_2 () #2 0x00000000004baab9 in rte_acl_classify () #3 0x000000000047d12d in test_acl () #4 0x000000000041c535 in cmd_autotest_parsed () #5 0x00000000004d8503 in cmdline_parse () #6 0x00000000004d7600 in cmdline_valid_buffer () #7 0x00000000004da43a in rdline_char_in () #8 0x00000000004d7809 in cmdline_interact () #9 0x000000000041bccb in main () > > Thanks > Konstantin > > >
