Thanks Konstantin. Previous allocation error was coming with 1024 huge pages of 2 MB size.
After increasing the huge pages to 2048, I was able to add another ~140 rules [IPv4 rule data--> with src, dst IP address & port, next header ] more, ie., 950 rules were added. Logically it did not increase number of rules [expected 2*817, but only 950 were added]. Is it really using huge pages memory only? >From the code it looks like heap memory. [ ret = >malloc_heap_alloc(&mcfg->malloc_heaps[i], type, size, 0, align == 0 ? 1 : >align, 0) ] > -----Original Message----- > From: dev [mailto:dev-bounces at dpdk.org] On Behalf Of Rapelly, Varun > Sent: Friday, February 26, 2016 10:28 AM > To: dev at dpdk.org > Subject: Re: [dpdk-dev] ACL memory allocation failures > > Hi All, > > When I'm trying to configure some 5000+ ACL rules with different > source IP addresses, getting ACL memory allocation failure.
