Use __SCCSID for SCCS IDs in libkvm sources. Rather than using #ifdef's around a static char array, use the existing helper macro from <sys/cdefs.h> for SCCS IDs. To preserve existing behavior, add -DNO__SCCSID to CFLAGS to not include SCCS IDs in the built library by default.

General further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Add support to libkvm for reading vmcores from other architectures. - Add a kvaddr_type to represent kernel virtual addresses instead of unsigned long. - Add a struct kvm_nlist which is a stripped down version of struct nlist that uses kvaddr_t for n_value. - Add a kvm_native() routine that returns true if an open kvm descriptor is for a native kernel and memory image. - Add a kvm_open2() function similar to kvm_openfiles(). It drops the unused 'swapfile' argument and adds a new function pointer argument for a symbol resolving function. Native kernels still use _fdnlist() from libc to resolve symbols if a resolver function is not supplied, but cross kernels require a resolver. - Add a kvm_nlist2() function similar to kvm_nlist() except that it uses struct kvm_nlist instead of struct nlist. - Add a kvm_read2() function similar to kvm_read() except that it uses kvaddr_t instead of unsigned long for the kernel virtual address. - Add a new kvm_arch switch of routines needed by a vmcore backend. Each backend is responsible for implementing kvm_read2() for a given vmcore format. - Use libelf to read headers from ELF kernels and cores (except for powerpc cores). - Add internal helper routines for the common page offset hash table used by the minidump backends. - Port all of the existing kvm backends to implement a kvm_arch switch and to be cross-friendly by using private constants instead of ones that vary by platform (e.g. PAGE_SIZE). Static assertions are present when a given backend is compiled natively to ensure the private constants match the real ones. - Enable all of the existing vmcore backends on all platforms. This means that libkvm on any platform should be able to perform KVA translation and read data from a vmcore of any platform. Tested on: amd64, i386, sparc64 (marius) Differential Revision: https://reviews.freebsd.org/D3341

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Teach libkvm how to read minidumps. It turns out that minidumps are far more convenient for libkvm to work with because of the page table block at the beginning. As a result, the MD code is smaller. libkvm will automatically detect old vs mini dumps on i386 and amd64. libkvm will handle i386 PAE and non-PAE modes. There is a PAE flag in the i386 minidump header to signal the width of the entries in the page table block. Other convenient values are also present, such as kernbase and the direct map addresses on amd64.

Fix a well duplicated fencepost error that stopped crashdumps being readable on certain random memory configurations. If the libkvm consumer tried to read something that was in the very last pdpe, pde or pte slot, it would bogusly fail. This is broken in RELENG_6 too.

Support crash dumps > 4GB in size on 32 bit platforms. _kvm_kvatop() 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. Approved by: re

Use kldsym(2) to lookup symbol values. This avoids the kvm_mkdb juggling and is module aware. Yes, this means that kvm_nlist(3) will find symbols in loaded modules. The emulation of the nlist struct is pretty crude but seems to work well enough for all the users in the tree that I found.

Implement virtual-to-physical address mapping for the kvm library on dead kernel debugging. The previous code was a "do nothing". The most obvious side effect of this is that you can now do things like this and reasonably expect them to work: dmesg -M /var/crash/vmcore.3 -N /var/crash/kernel.3 ps -axl -M /var/crash/vmcore.3 -N /var/crash/kernel.3 A good deal of this was lifted from the gdb code to do this, as well as from NetBSD's libkvm (which has completely different VM macros)
