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.

KVM_XARCH=${TARGET_ARCH}
Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental. This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit. This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.

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.

SRCS= kvm.c kvm_${KVM_ARCH}.c kvm_cptime.c kvm_file.c kvm_getloadavg.c \
Make libkvm work on live systems and crashdumps with and without VIMAGE virtualization in the kernel. If we cannot resolve a symbol try to see if we can find it with prefix of the virtualized subsystem, currently only "vnet_entry" by identifying either the vnet of the current process for a live system or the vnet of proc0 (or of dumptid if compiled in a non-default way). The way this is done currently allows us to only touch libkvm but no single application. Once we are going to virtualize more subsystems we will have to review this decision for better scaling.

SRCS+= kvm_minidump_${KVM_ARCH}.c
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.

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
