tm6000 + audio

tm6000 + audio

[Stefan Ringel]

Mauro,

I have great problems with _tm6000_start_audio_dma if I started mencoder
or arecord. It creashed and after a while it frosts in. (It hasn't logged).

[PATCH v2] tm6000+audio

[Dmitri Belimov]

[-- Attachment #1: Type: text/plain, Size: 6379 bytes --]

Hi 

I rework my last patch for audio and now audio works well. This patch can be submited to GIT tree
Quality of audio now is good for SECAM-DK. For other standard I set some value from datasheet need some tests.

1. Fix pcm buffer overflow
2. Rework pcm buffer fill method
3. Swap bytes in audio stream
4. Change some registers value for TM6010
5. Change pcm buffer size

This didn't seem to work for PAL-M. Probably, the right value for it is 0x22, to
follow NTSC/M, since both uses the same audio standard.

On some tests, I was able to receive some audio there, at the proper rate, with a
tm6010-based device. It died when I tried to change the channel, so I didn't rear
yet the real audio, but I suspect it will work on my next tests.

Yet, is being hard to test, as the driver has a some spinlock logic broken.
I'm enclosing the logs.

I was able to test only when using a monitor on the same machine. All trials of
using vnc and X11 export ended by not receiving any audio and hanging the machine.

I suspect that we need to fix the spinlock issue, in order to better test it.

Cheers,
Mauro.

Well, any of us ;)

I did a BKL lock fix series of patches, and hverkuil is improving them.
They'll make easier to avoid problems inside tm6000. We just need to make
sure that we'll hold/release the proper locks at tm6000-alsa, after applying
it at the mainstream.

I found that mplayer crashed when call usb_control_msg and kfree functions.

Yeah, you can't call usb_control_msg at trigger callback. Some of those callbacks
seem to happen at IRQ time. With respect to kfree, that's weird.

The same troubles with alsa is also happening, at some extent, with em28xx and cx231xx.

I did a patch yesterday for cx231xx-audio to avoid using usb_control_msg (see enclosed).
This seems to solve part of the bugs, but I still got an OOPS when s_frequency call
happens while alsa is starting. So, I suspect that this patch, plus the ioctl locking
at the video part may solve the issue, but more tests are required.

Cheers,
Mauro.

tm6000 and new TV card

[Dmitri Belimov]

Hi 

Some times a go I received mail from Yogesh S <yogaishrs@gmail.com>.
He has TV card based on the tm5600 chip. His card is http://www.zebronics.net/Usb_tvtuners.asp
and has USB ID as (vid:6000,pid:0001). This IDs already captured by 10MOONS_UT821 TV card.
Who has the 10MOONS_UT821 TV card and can make some photos inside??

If this cards is different how we can add support zebronics TV tuner?

With my best regards, Dmitry.
