* Add support to libkvm for reading vmcores from other architectures.John Baldwin2015-11-2735-1560/+2352
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

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.

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. Notes: svn path=/head/; revision=260599

Common ia64-specific support functions have the ia64_ prefix. 2. Functions that work on physical cores have the phys_ prefix. 3. Functions that work on virtual cores have the virt_ prefix. With that: 1. _kvm_kvatop() has been renamed to phys_kvatop() as it handles physical cores only. 2. The new _kvm_kvatop() is nothing but a wrapper that calls either phys_kvatop() or virt_kvatop() by virtue of the kvatop function pointer in the vmstate structure. 3. virt_kvatop() is nothing but a wrapper around virt_addr2off(). 4. virt_addr2off() iterates over the Phdrs to find the segment in which the address falls and return the file offset for it. Now it's up to the kernel to populate the core file appropriately. Notes: svn path=/head/; revision=260028
