It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.

One of the important things the following patch series does is separate the VIO layer from the hvc_console code. With the VIO specific code removed any ppc64 platform, or even any architecture, can use hvc_console as a generic polling console. You simply have to supply a get_chars and put_chars method and hvc_console does the rest of the work. You can even use it for an interrupt driven console. This patch: Rearrange the code in drivers/char/hvc_console.c to make future patches smaller. No actual code changes, just ordering of the functions in the file.

BTW the core problem is that part of this should be handled in the receive_buf path, but for this it has to return the number of written characters, as the amount of written characters may not be the same as the amount of characters going into the write buffer, so the receive_room() usage in pty_write() is not really reliable. Alan said: The problem looks valid. The behaviour of 'traditional unix' appears to be the following If you exceed the line limit then beep and drop the character Always allow EOL to complete a canonical line input Always do signal/control processing if enabled Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/n_tty.c | 33 +++++++++++++++------------------ 1 file changed, 15 insertions(+), 18 deletions(-) (limited to 'drivers/char') diff --git a/drivers/char/n_tty.c b/drivers/char/n_tty.c index edba5a35bf2..09103b3d8f0 100644 --- a/drivers/char/n_tty.c +++ b/drivers/char/n_tty.c @@ -770,10 +770,8 @@ send_signal: } if (c == '\n') { if (L_ECHO(tty) || L_ECHONL(tty)) { - if (tty->read_cnt >= N_TTY_BUF_SIZE-1) { + if (tty->read_cnt >= N_TTY_BUF_SIZE-1) put_char('\a', tty); - return; - } opost('\n', tty); } goto handle_newline; @@ -790,10 +788,8 @@ send_signal: * XXX are EOL_CHAR and EOL2_CHAR echoed?!? */ if (L_ECHO(tty)) { - if (tty->read_cnt >= N_TTY_BUF_SIZE-1) { + if (tty->read_cnt >= N_TTY_BUF_SIZE-1) put_char('\a', tty); - return; - } /* Record the column of first canon char. */ if (tty->canon_head == tty->read_head) tty->canon_column = tty->column; @@ -862,12 +858,9 @@ static int n_tty_receive_room(struct tty_struct *tty) * that erase characters will be handled.

In that case all processors in an SMP system must needlessly reload the cachelines again and again containing elements of those frequently used variables.
