> Subject: any plans for soundriver or bktr?
since amancio and I have been working a lot on both bktr and audio in
the last months I feel entitled to comment on this.
* bktr:
there are several, slightly different versions of the code, all of
them pretty robust, tested and supported. [there are minor
differences in the versions, e.g. I have rewritten the code for the
dma engine, someone else might have added some ioctls, etc., but
basically they all work fine] Since the driver was not
there before, it works quite well, and is well supported, I'd strongly
suggest to include one driver (ask amancio which ones he feels more
comfortable with) in 2.2.5, just do not put it into the generic
kernel (and the reason is not stability, the reason is that attaching
the card eats a lot of memory for the frame buffer).
Also we should make a port of fxtv, and update vic drivers.
(also, fxtv is probably a small program; does people agree that for
each driver there ought to be, in the standard distribution, at least
one small program to test the driver ? If this is the case, fxtv
could go into /usr/bin)
* sounddriver
here things are messy: the current driver (3.0) is not well supported;
amancio has put a lot of work in a 3.5 derivative, and works with
many more cards than the 3.0 I think. Applications should work at
least as with the past driver.
My brand new driver only does pcm right now, although I have it
working in full duplex with vat, nas, and with most if not all
half-duplex apps, including rplay and timidity [the latter converts a
midi file to pcm data, so you basically do not need opl3/opl4
support, if you have some cpu cycles to spare].
In 1 month I don't think I have the time to make it support all
the boards I would like to.
So my suggestion is:
- ask amancio if he feels like replacing the current sound driver with
his version of guspnpXX, which has basically the same features (and
probably fewer bugs) than the currently committed one;
- put my driver (and guxpnpXX as well, if amancio does not feel like
replacing the current code for 2.2.5) in the "experimental" part of
the tree.
Cheers
Luigi
