2010-02-03Use MACHINE_CPU instead of MACHINE_ARCH to pick the correct machine dependentMiod Vallat
files or directories when applicable. The inspiration and name of MACHINE_CPU come from NetBSD, although the way to provide it to Makefiles is completely different. ok kettenis@
2010-01-12the comment is right, this can indeed go away.Jasper Lievisse Adriaanse
it's unused inside libkvm, and nothing else is allowed to use it. ok guenther@ "sure" deraadt@
2010-01-10Reimplement kvm_getproc2()'s support for reading crash dumps andPhilip Guenthe
/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.
2009-12-07Get page size information by reading the kernel image' struct uvmexp, insteadMiod Vallat
of the value of PAGE_SIZE found in the standard headers when compiling.
2009-11-22Oops, KSEG -> CKSEG.Miod Vallat
2009-11-22Allow mips ports to override VM_{MIN,MAX}_KERNEL_ADDRESS, and provide theMiod Vallat
address as a kernel variable for use by libkvm. On sgi IP27 and IP30 kernels, use XKSEG instead of CKSSEG; this will allow kernel KVM size to grow in the future if necessary.
2009-10-28Do not need -DLIBC_SCCS anymoreTheo de Raadt
2009-10-28rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andTheo de Raadt
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

2009-06-07Define _KERNEL for the bare minimum. We can include sys/proc.hTodd C. Miller
normally as long as we define __need_process and use a local definition of struct proclist.
2009-06-07Avoid including machine/cpu.hTodd C. Miller
2009-06-07Add kvm_getfile2 which uses KERN_FILE2 when possible, fallingTodd C. Miller
back on kmem grovelling for non-live kernels. OK deraadt@
2009-03-30Mop up after oga@ and unbreak the tree. The direct uncached map is gone soMark Kettenis
remove the code from libkvm that dealt with it.
2009-01-21All operation on live kernels uses sysctl interface, there is no reason toMiod Vallat
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.
2009-01-02Sync _kvm_kvatop with existing pmap code: handle direct mappings andMiod Vallat
level 2 large pages.
2008-06-26First pass at removing clauses 3 and 4 from NetBSD licenses.Ray Lai
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@
2008-03-30Unbreak build.Mark Kettenis
2007-10-18Get rid of the silly union for mips pte. No functional change exceptMiod Vallat
pmap.h now includes pte.h.
2007-10-10Make context switching much more MI:Artur Grabowski
- 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
2007-06-18Bring back Mickey's UVM anon change. Testing by thib@, beck@ andPedro Martelletto

2007-05-19Kernel crash dump support for arm-based platform, with minimal support inMiod Vallat
libkvm, but all the necessary information for a complete _kvm_kvatop() is available in the crash dump.
2007-05-03Enable support for > 512MB of physical memory on mips64 systems, by usingMiod Vallat
XKPHYS instead of KSEG[01] for direct mappings. Then, detect memory above 256MB on O2 by poking at the CRIME registers (ARCbios will not report memory above 256MB, which is mapped above 1GB physical, to the system), and add it to the UVM managed memory. Tested on r5k, rm5200 and r10k with and without more than 256MB, matching hinv reports in all cases. CRIME memory decoding based on a diff from kettenis@ in december 2005.

2006-07-13Back out the anon change. Apparently it was tested by a few, but most ofTheo de Raadt
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.
