dbaf74ae49 Check return value of _kvm_initvtop(). 1996-11-09 23:44:53 +00:00

e79d25e2e9 Don't use a kernel database based on the file name, use only 
/var/db/kvm.db, and only use that if no kernel namelist file
is named.  Update the documentation to describe this.

2af2958a7d add code so that if kvm_nlist() failed because __fdnlist() failed, 
kvm_geterr() actually provides useful information rather than just an
empty string.

fa72190309 Fix the empty error message problem more completely. When the magic-check 
fails on the cpu_hdr, return 0 instead of -1. This allows the caller to
distinguise between fatal errors and 'nothing there'.

cca068a144 Fix the mysterious empty error message when savecore is executed and no 
dump is present. This was caused by the fact that kvm_dump_mkheader() was
called *before* savecore checks the dump magic and kvm_dump_mkheader() returned
-1 without setting an error message. The latter is fixed now.

82118b75d6 Allow more flexibility in the format of cpu_kcore_hdr_t and isolate 
the knowledge of that struct in the machine-dependent module.

9c2128ecdd New libkvm/savecore implementation. With the following differences: 
1) savecore will not access the dump or live-kernel directly. It
        will always use the kvm-functions. Allowing it to work on kernels
        that don't have a 1-1 PA-VA mapping.
     2) the kvm-lib has some additional functions to accomplish 1
          - kvm_dump_mkheader()
          - kvm_dump_wrtheader()
          - kvm_dump_inval()
     3) the file formats of the dump generated by the kernel and the dump
        generated by savecore have been changed. The file format now looks
        like the format produced for 'normal' core dumps.
Ports not yet supporting the new kvm-format will be using libkvm.old/
savecore.old for the time being.

00fd6050b6 slight type cleanup. add some prototypes for internal functions, 
some 'const' poisoning, some lvalue lossage.

from example code in kvm_getu, plus hacks
