* The si_status field of the siginfo_t, provided by the waitid(2) andkib2015-07-181-1/+3
| | | | | | | | | | | | | | | | SIGCHLD signal, should keep full 32 bits of the status passed to the _exit(2). Split the combined p_xstat of the struct proc into the separate exit status p_xexit for normal process exit, and signalled termination information p_xsig. Kernel-visible macro KW_EXITCODE() reconstructs old p_xstat from p_xexit and p_xsig. p_xexit contains complete status and copied out into si_status.

| | | | | | | | | Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere. This makes /lib being populated again. Reported by: many

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
