- Remove per-thread errno from the TCB structure (pterrno) - Remove get_errno() and set_errno() as functions. The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode). - Add errno value to the tls_info_s structure definitions - Move sched/errno to libs/libc/errno. Replace old TCB access to the errno with TLS access to the errno. |

arch/x86/src/README.txt ^^^^^^^^^^^^^^^^^^^^^^^ This directory holds x86-specific source files. All x86 source reside in lower-level common, chip-specific, and architecture-specific directories. common/ Directory ^^^^^^^^^^^^^^^^^ This directory holds source files common to all x86 architectures. Architecture-Specific Directories ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Architecture-specific directories hold common source files shared for by implementations of specific x86 architectures. i486 This directory holds logic appropriate for any instantiation of the 32-bit i486 architecture. Chip-Specific directories ^^^^^^^^^^^^^^^^^^^^^^^^^ The same x86 architecture may be realized in different chip implementations. For SoC chips, in particular, on-chip devices and differing interrupt structures may require special, chip-specific definitions in these chip- specific directories. qemu This is the implementation of NuttX on the QEMU x86 simulation.
