--- Comment #3 from Sad Clouds <[email protected]> --- (In reply to Stefan Roesch from comment #2) Yes, I noticed this as well. As far as I remember, superpages were enabled by default (see the comments in the attached test program) but no S flag displayed when allocating large pages via shm_create_largepage(). As far as I understand, FreeBSD supports transparent large pages and explicit large pages. The shm_create_largepage() seems to be the only API which allocates explicit large pages. Both Linux and Solaris also support explicit large page allocation via mmap(). With FreeBSD and when using shm_create_largepage() I was expecting "procstat vm" to display the total page count of large pages. If it is not designed to do that (i.e. always defaults to the base page size and then prints S flag) then it would be useful for procstat man page to explicitly elaborate on that. -- You are receiving this mail because: You are the assignee for the bug.
