Inspired by gdb command 'list', show the code context of target lines. Here is a example: $ scripts/faddr2line vmlinux native_write_msr+0x6 native_write_msr+0x6/0x20: arch_static_branch at arch/x86/include/asm/msr.h:105 100 return EAX_EDX_VAL(val, low, high); 101 } 102 103 static inline void notrace __wrmsr(unsigned int msr, u32 low, u32 high) 104 { 105 asm volatile("1: wrmsr\n" 106 "2:\n" 107 _ASM_EXTABLE_HANDLE(1b, 2b, ex_handler_wrmsr_unsafe) 108 : : "c" (msr), "a"(low), "d" (high) : "memory"); 109 } 110 (inlined by) static_key_false at include/linux/jump_label.h:142 137 #define JUMP_TYPE_LINKED 2UL 138 #define JUMP_TYPE_MASK 3UL 139 140 static __always_inline bool static_key_false(struct static_key *key) 141 { 142 return arch_static_branch(key, false); 143 } 144 145 static __always_inline bool static_key_true(struct static_key *key) 146 { 147 return !arch_static_branch(key, true); (inlined by) native_write_msr at arch/x86/include/asm/msr.h:150 145 static inline void notrace 146 native_write_msr(unsigned int msr, u32 low, u32 high) 147 { 148 __wrmsr(msr, low, high); 149 150 if (msr_tracepoint_active(__tracepoint_write_msr)) 151 do_trace_write_msr(msr, ((u64)high << 32 | low), 0); 152 } 153 154 /* Can be uninlined because referenced by paravirt */ 155 static inline int notrace Link: http://lkml.kernel.org/r/1521444205-2259-1-git-send-email-changbin.du@intel.com Signed-off-by: Changbin Du <changbin.du@intel.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Philippe Ombredanne <pombredanne@nexb.com> Cc: NeilBrown <neilb@suse.com> Cc: Richard Weinberger <richard@nod.at> Cc: Kate Stewart <kstewart@linuxfoundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
