This is basically the contents of /proc/$$/maps, and is necessary in order to place kprobes, relocate unwind/symbol data, and probably other stuff too. Some of it needs to be available by probe initialization (uprobe placement) time. It needs to be kept reasonably up to date, and readable without taking sleepy locks (for backtrace purposes). -- Summary: process memory map tracker Product: systemtap Version: unspecified Status: NEW Severity: normal Priority: P2 Component: runtime AssignedTo: systemtap at sources dot redhat dot com ReportedBy: fche at redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=5236 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 3+ messages in thread

If you could create an initial map (possibly in a sleepy context) and then catch map changes as they happen, you could have an up-to-date version available even in can't-sleep contexts. -- http://sourceware.org/bugzilla/show_bug.cgi?id=5236 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 3+ messages in thread
