Hello. Looking at your pull request, I see that my patch for correct
buffer handling when using .stop_src = TRIG_NONE is not included. Does
the patch need some more work? Or it simply get lost on the way?
Thanks. Cheers,

I have not forgotten it. I did not include it for two reasons:
- I have not found time to (fully) test it
- I wanted to properly modify the test program cmd_read so as to allow
continuous acquisisitions

Hi Alexis. Sorry for the late response. That's fine, I just wanted to be
sure that the patch was not dropped by mistake. I'll test continuous
output today and let you know if any other bugfix is necessary. I can
also look into providing a patch for cmd_read and cmd_write.
Cheers,

If you want to test infinite acquisitions right now, you can clone my
git repository. I just pushed the modifications on it. I have not made
a pull request yet because I want to be sure there is no regression.
Your patch did not integrate fixes for both directions (read and
write). So, I had to modify it.
I also modified cmd_read; with the option -S set to 0, an infinite
acquisition will be configured.
Any patch from you is welcome (cmd_write or anything else), so do not
hesitate to send them.

Thanks! I'll test it as soon as possible.
I think I just stumbled into the ring buffer bug you fixed in your
repository :-) It took me a while to understand if the problem was in
the hardware, in my code, or somewhere else in the stack...
Now I just have to find where the carpenters broke the cable that brings
internet connection to my lab and fix it... :-(

I'm testing it now.

Unfortunately my ring buffer problem is not fixed by you patch. What I'm
experiencing is exposed by this (pseudo) code:
a4l_open(dsc, device)
a4l_mmap(dsc, subdevice, bufsize, &map)
a4l_snd_command(dsc, cmd)
/* preload buffer */
written = write_to_buffer(map, bufsize)
/* send internal trigger */
a4l_snd_insn(dsc,
cnt = 0;
while (1)
a4l_mark_bufrw(dsc, subdevice, written, towrite);
cnt += written;
/* 1 */
written = write_buffer(map + (cnt % bufsize), towrite)
The problem is that at the place marked with (1) the total extension of
the buffer region that gets written exceeds the ring buffer allocated
memory. That is ((cnt % bufsize) + towrite) > bufsize !
I do not know if this should be handled in my code, or in the driver.
This situation is not handled in the cmd_write example code (where a
simple memcpy() is done).
What do you think?
Cheers,

There is a bug in cmd_write and cmd_read. I have should have taken
into account the buffers edges. I will fix it. The function
a4l_mark_bufrw() is not designed to handle boundaries, that is why its
arguments represent data size not addresses.

That makes sense. I can provide a patch for cmd_read and cmd_write, as i
got the same kind of code working in my own test programs, but I'm quite
busy right now...
