Hi Alan,
Thanks for your help, I might give this ago once I've
fixed some flow control problems in my driver.
On a loosely related topic I have extended
serial_core.c to handle DMA UARTS (only the TX path is
effected). Once I'm happy with my changes I post a
patch.
Best Regards,
Mark

In theory you can do that already, although the locking is a bit screwed
up
Hi Rogier,
Having just written a DMA UART driver I can say this
is good news :-). Here are some things to think about:
What my driver would like to do is to handle its own
input buffers. It would pass the buffer to the tty
layer when it is full and the tty layer would pass the
buffer back once it

tty_flip_buffer_push() (or its possibly renamed equivalent). At that
point as now the buffer may get processed or queued to the ldisc. At
that point its

At the moment tty buffers are attached directly to the tty. This is
causing a lot of the problems related to tty layer locking, also
problems at high speed and also with bursty data (such as occurs in
virtualised environments)
I'm working on ripping out the flip buffers and replacing them with a
