LIB= kvm
Re-apply the part of r260022 that was reverted by r260030 with one significant difference: for LIB32 builds both TARGET_ARCH and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the architecture of the host (e.g. amd64), while MACHINE_ARCH holds the architecture were trying to build (e.g. i386). With both set and different, r260022 changed the behaviour to interpret the condition as building a cross-amd64 libkvm on i386, when obviously we're trying to build an i386 version on amd64. When COMPAT_32BIT is defined, we're building LIB32 and ignore the value of TARGET_ARCH as we did before.

SHLIBDIR?= /lib
In r227839, when removing libkvm dependency on procfs(5), kvm_uread() function, used for reading from /proc/pid/mem, was removed too. But the function declaration remained in kvm.h public header and the soname was not bumped. Remove kvm_uread() from kvm.h and bump the soname. Reported by: rmh Discussed on: arch

libkvm: fix process runtime calculation on crashdumps Fix a long standing bug, where the procs ticks where assumed to be in us. Instead, read cpu_tick_frequency from the kernel and use the same logic to convert runtime. This is still too optimistic in that it assumes cpu_tick_frequency is available and fixed. Since this function is only called on crashdumps, I think we can live with that. Testing has shown the values to be correct for different kern.hz inside Virtualbox. Bump WARNS. Alignment issues on some archs mean this is still at 3. Reviewed by: bde

WARNS?= 3
Build lib/ with WARNS=6 by default. Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and lower it when needed. I'm setting WARNS?=0 for secure/. It seems secure/ includes the Makefile.inc provided by lib/. I'm not going to touch that directory. Most of the code there is contributed anyway.

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.

LIBADD= elf
Add a new routine kvm_getcptime(3) for fetching the equivalent of 'kern.cp_time'. For a live kernel it uses the sysctl. For a crashdump, it first checks to see if the kernel has a 'cp_time' global symbol. If it does, it uses that. If that doesn't work, when it uses the recently added kvm_getmaxcpu(3) and kvm_getpcpu(3) routines to walk all the CPUs and sum up their counters. MFC after: 1 week
