We could either fix VM_MIN_ADDRESS to always be a simple integer or make the check conditional on $ARCH. Closes PRs: kern/42386, kern/83364 Reviewed by: bde Fix missing includes of <string.h>, to silence some compiler warnings. 2009-06-14T12:42:06Z Ed Schouten ed@FreeBSD.org 2009-06-14T12:42:06Z urn:sha1:953e4134b5b3948e32f9f0066d2f5cc8d7146c9c Submitted by: Pawel Worach Support kernel crash mini dumps on ARM architecture. 2008-11-06T16:20:27Z Rafal Jaworowski raj@FreeBSD.org 2008-11-06T16:20:27Z urn:sha1:8e321b79437e9e70ff57785e8508c1d2734d8a7f Obtained from: Juniper Networks, Semihalf Per Olivier Houchard, use the proper license for this file.

The only thing from the kvm_powerpc.c file was the license. Correct this mistake with his blessing. libkvm bits for arm. 2005-10-03T14:21:14Z Olivier Houchard cognet@FreeBSD.org 2005-10-03T14:21:14Z urn:sha1:9960ac47e9b6e0a7e5239ebc87dd3990f3daa130 Support crash dumps > 4GB in size on 32 bit platforms. _kvm_kvatop() 2005-06-29T22:39:41Z Peter Wemm peter@FreeBSD.org 2005-06-29T22:39:41Z urn:sha1:e55a0cd805e090e95a80e45f1822cb9a81981d3c returned an lseek offset in a "u_long *" value, which can't express >4GB offsets on 32 bit machines (eg: PAE). Change to "off_t *" for all. Support ELF crashdumps on i386 and amd64. Support PAE crashdumps on i386. This is done by auto-detecting the presence of the IdlePDPT which means that PAE is active. I used Marcel's _kvm_pa2off strategy and ELF header reader for ELF support on amd64. Paul Saab ported the amd64 changes to i386 and we implemented the PAE support from there. Note that gdb6 in the src tree uses whatever libkvm supports. If you want to debug an old crash dump, you might want to keep an old libkvm.so handy and use LD_PRELOAD or the like. This does not detect the old raw dump format.
