From be90038a24c814dc98bc5a813f41855779000018 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 8 Dec 2006 02:38:43 -0800 Subject: [PATCH] tty: preparatory structures for termios revamp In order to sort out our struct termios and add proper speed control we need to separate the kernel and user termios structures. Glibc is fine but the other libraries rely on the kernel exported struct termios and we need to extend this without breaking the ABI/API To do so we add a struct ktermios which is the kernel view of a termios structure and overlaps the struct termios with extra fields on the end for now. (That limitation will go away in later patches). Some platforms (eg alpha) planned ahead and thus use the same struct for both, others did not. This just adds the structures but does not use them, it seems a sensible splitting point for bisect if there are compile failures (not that I expect them) Signed-off-by: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/asm-m68k/termbits.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'include/asm-m68k') diff --git a/include/asm-m68k/termbits.h b/include/asm-m68k/termbits.h index e9eec3eb0718..a194092240fb 100644 --- a/include/asm-m68k/termbits.h +++ b/include/asm-m68k/termbits.h @@ -17,6 +17,17 @@ struct termios { cc_t c_cc[NCCS]; /* control characters */ }; +struct ktermios { + tcflag_t c_iflag; /* input mode flags */ + tcflag_t c_oflag; /* output mode flags */ + tcflag_t c_cflag; /* control mode flags */ + tcflag_t c_lflag; /* local mode flags */ + cc_t c_line; /* line discipline */ + cc_t c_cc[NCCS]; /* control characters */ + speed_t c_ispeed; /* input speed */ + speed_t c_ospeed; /* output speed */ +}; + /* c_cc characters */ #define VINTR 0 #define VQUIT 1 -- cgit v1.2.3
