* Need to read in the vmspace to dig out the root of the rb-treeguenther2012-04-141-2/+5

* Userspace counterpart of new vmmap.ariane2012-03-091-13/+14
| | | | Allows memory walks to function.
* Add rtable id and thread id to struct kinfo_proc (and fix process id)guenther2012-01-071-13/+1
| | | | | | | | | | | and add an 'rtableid' keyword to ps. Add rtable id, thread id, and socket splice info to struct kinfo_file2 and make fstat display socket splice information. Remove old KVM_PROC2 and kinfo_proc2 interfaces; bump libkvm major Socket splice info and corrections from bluhm@ "Lovely" deraadt@
* Userland counterpart of the vmmap backout; cranks major version of libkvm.ariane2011-06-061-14/+13

* Reimplement uvm/uvm_map.ariane2011-05-241-13/+14
| | | | | | | | | | | | | vmmap is designed to perform address space randomized allocations, without letting fragmentation of the address space go through the roof. Some highlights: - kernel address space randomization - proper implementation of guardpages - roughly 10% system time reduction during kernel build Tested by alot of people on tech@ and developers. Theo's machines are still happy.
* Replace the old, broken KERN_PROC ABI and its matching functionsguenther2011-03-121-310/+13
| | | | | | | | | in libkvm with the stable-ABI versions that are currently named KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols will continue to be supported for a few releases. Committing now that they ports people have had a couple releases to update pkgs that usd the old functions
* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-6/+7
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots
* Reimplement kvm_getproc2()'s support for reading crash dumps andguenther2010-01-101-199/+1
| | | | | | | | | | | | | | /dev/mem to be direct instead of going through kvm_getprocs(), as that function is going to get more an more broken as we move stuff from struct proc to struct process for rthreads. To minimize the code copying, put the common logic of filling in a kinfo_proc2 structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from both the kernel and user-space. This also hides the KERN_PROC #define behind "#if defined(_KERNEL)||defined(_LIBKVM)", as it's deprecated. Positive feedback from millert and blambert; so committing to unblock further rthreads work.
* rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andderaadt2009-10-271-9/+1
| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
* Move KREAD define to kvm_private.hmillert2009-06-201-5/+2

* All operation on live kernels uses sysctl interface, there is no reason tomiod2009-01-211-3/+4
| | | | | | access the swap area. Change kvm_open() to no longer require a swap area, and to not consider failure to open() it as fatal. Post-mortem analysis would need an image of the swap area at the time of the crash, anyway.
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-9/+2
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Make context switching much more MI:art2007-10-101-4/+2
| | | | | | | | | | | | | | | | | | | | - Move the functionality of choosing a process from cpu_switch into a much simpler function: cpu_switchto. Instead of having the locore code walk the run queues, let the MI code choose the process we want to run and only implement the context switching itself in MD code. - Let MD context switching run without worrying about spls or locks. - Instead of having the idle loop implemented with special contexts in MD code, implement one idle proc for each cpu. make the idle loop MI with MD hooks. - Change the proc lists from the old style vax queues to TAILQs. - Change the sleep queue from vax queues to TAILQs. This makes wakeup() go from O(n^2) to O(n) there will be some MD fallout, but it will be fixed shortly. There's also a few cleanups to be done after this. deraadt@, kettenis@ ok
* Bring back Mickey's UVM anon change. Testing by thib@, beck@ andpedro2007-06-181-3/+3
| | | | ckuethe@ for a while. Okay beck@, "it is good timing" deraadt@.
* hide struct process from userland, allow kvm_proc to see it.espie2007-04-141-2/+3

* Back out the anon change. Apparently it was tested by a few, but most ofderaadt2006-07-131-3/+3
| | | | | us did not see it or get a chance to test it before it was commited. It broke cvs, in the ami driver, making it not succeed at seeing it's devices.
* from netbsd: make anons dynamically allocated from pool.mickey2006-06-211-3/+3
| | | | | | this results in lesse kva waste due to static preallocation of those for every phys page and also every swap page. tested by beck krw miod
* careful cleanup following advice from lint. be very very very carefulderaadt2006-03-311-10/+10

* Use queue macros instead of directly accessing fields. ok millert@otto2005-10-121-3/+3

* Back out part of last commit; we want to realloc + loop for argv too.millert2004-06-241-3/+3

* Allocate 8 pages for process argv, not one. This should really be ARG_MAXmillert2004-06-241-5/+5
