#15348: Enable two-step allocator on FreeBSD -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: feature request | Status: patch Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | Keywords: Operating System: FreeBSD | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4939 Wiki Page: | -------------------------------------+------------------------------------- Comment (by vdukhovni): I modified the proposed OSMem.c patch as attached ,rebuilt GHC-8.4.3 and am now running my DANE scanner (runs for ~8 hours, using around 300MB of VM space, and doing a total of around 4TB of allocations). So far so good. And it did allocate a 1TB hole in its address space, partly replaced with actually allocated pages. Because this is a reserved hole, and not a mapping, the reported virtual size is still modest. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15348#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
