From 76c03152e110dcb770253b54277811228e8f78df Mon Sep 17 00:00:00 2001 From: Amaan Cheval Date: Mon, 9 Jul 2018 16:42:56 +0530 Subject: bsp/x86_64: Minimal bootable BSP Current state: - Basic context initialization and switching code. - Stubbed console (empty functions). - Mostly functional linker script (may need tweaks if we ever want to move away from the large code model (see: CPU_CFLAGS). - Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for UEFI-awareness. In short, the current state with this commit lets us boot, go through the system initialization functions, and then call user application's Init task too. Updates #2898. --- cpukit/score/cpu/x86_64/cpu.c | 83 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 83 insertions(+) create mode 100644 cpukit/score/cpu/x86_64/cpu.c (limited to 'cpukit/score/cpu/x86_64/cpu.c') diff --git a/cpukit/score/cpu/x86_64/cpu.c b/cpukit/score/cpu/x86_64/cpu.c new file mode 100644 index 0000000000..308d231186 --- /dev/null +++ b/cpukit/score/cpu/x86_64/cpu.c @@ -0,0 +1,83 @@ +/** + * @file + * + * @brief x86_64 Dependent Source + */ + +/* + * Copyright (c) 2018. + * Amaan Cheval + * + * Copyright (c) 1989-1999. + * On-Line Applications Research Corporation (OAR). + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
