Damjan, On the VPP call yesterday, you described the patch you are working on to rework how VPP allocates and uses hugepages. Per request from Jerome Tollet, I wrote VPP-958<https://jira.fd.io/browse/VPP-958> to document some issues they were seeing. I believe your patch will address this issue. I added a comment to the JIRA. Is my comment in the JIRA accurate? Save you from having to follow the link: Damjan Marion is working on a patch that reworks how VPP uses memory. With the patch, VPP will not need to allocate memory using 80-vpp.conf. Instead, when VPP is started, it will check to insure there are enough free hugespages for it to function. If so, it will not touch the current huge page allocation. If not, it will attempt to allocate what it needs. yes, it will pre-allocate delta. This patch also reduces the default amount of memory VPP requires. This is a fairly big change so it will probably not be merged until after 17.10. I believe this patch will address the concerns of this JIRA. I will update this JIRA as progress is made. yes This may not be the final patch, but here is the current work in progress: https://gerrit.fd.io/r/#/c/7701/ yes Thanks, Damjan
