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.

* | | | | | | | | Remove IPX support.Gleb Smirnoff2014-03-142-2/+0

The NetWare itself switched to TCP/IP as default transport in 1998. Later, in this century the Novell Open Enterprise Server became successor of Novell NetWare. The last release that claimed to still support IPX was OES 2 in 2007. Routing equipment vendors (e.g. Cisco) discontinued support for IPX in 2011. Thus, IPX won't be supported in FreeBSD 11.0-RELEASE. Notes: svn path=/head/; revision=263140

This is also happening for non-cross kgdb, by virtue of having fbsd-threads.c in libgdb and having it do the exact same thing. Since fbsd-threads.c is not included in in libgdb when building a cross debugger, we ended up with more than 1 core file targets (the standard gdb core file target and kgdb's libkvm based core file target) and this behaves the same as not having a core target at all.

* | | | KGDB: Allow modules to be loaded from the specified kernel's directory.Will Andrews2013-03-281-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When looking up the absolute path for a kld, call find_kld_path() first. This enables locating the module in a different directory than the one stored in kernel memory. With this change, kgdb can now be run on a kernel & vmcore whose associated modules are located in the same directory as the kernel. This makes independent triaging of problems much easier. This change also does not break the normal kgdb use case where no arguments are specified; in that case kgdb loads the running kernel and its modules.
