H A D | serial_txx9.c | c7d44a02 Mon Apr 21 12:06:43 CDT 2014 Doug Anderson <dianders@chromium.org> serial_core: Commonalize crlf when working w/ a non open console port
In (efe2f29 kgdboc,kdb: Allow kdb to work on a non open console port) support was added to directly use the "write_char" functions when doing kdb over a non-open console port. This is great, but it ends up bypassing the normal code in uart_console_write() that adds a carriage return before any newlines.
There appears to have been a trend to add this support directly in some console driver's poll_put_char() functions. This had a few side effects, including: - In this case we were doing LFCR, not CRLF. This was fixed in uart_console_write() back in (d358788 [SERIAL] kernel console should send CRLF not LFCR) - Not all serial drivers had the LFCR code in their poll_put_char() functions. In my case I was running serial/samsung.c which lacked it.
I've moved the handling to uart_poll_put_char() to fix the above problems. Now when I use kdb (and don't point console= to the same UART) I no longer get:
[0]kdb> [0]kdb> [0]kdb>
