I'm currently working on FC3 as well and successful with MythTV other
than the OSD Framebuffer feature on the PVR-350.

This PVR-350 IVTVDEV driver with Xorg doesn't work for me on 2.6.9 with
Xorg 6.8.1.  After starting/stopping X on my CLE266 chipset (KDE via
gdm) a few of times the IVTVDEV FB driver *may* work with X restarted
against the PVR-350 FB.  When the IVTVDEV FB doesn't work I see the
composite display wipe the top half of the display to black;  the bottom
half retains it's original pattern;  the X cursor displays in the
middle;  keyboard is locked up.

Since I am only a couple of weeks into this exercise I can't offer much
more at this time other than I am thinking about trying another
distribution (suspect kernel version and/or Xorg distribution).  I've
tried the 2.6.10 FC4 development kernel as well as played with my own
FC3 based kernels (stripped down to eliminate other modules).

If anyone has suggestions how to debug the ivtvdev driver (need to find
the source to start with), how to use the fbdev FB X driver, or knows
which of the ivtvdev_drv.o Framebuffer object files from badzzzz or
Chris Kennedy 0.2 or 0.3 genre are supposed to work with Xorg and
2.6.9., please let me know.

Thanks,

Quentin

Subject: [ivtv-devel] Fedora Core 3


I upgraded my PVR box to Core 3 recently and I am having issues with a 
couple of items.

1) The driver series greater then 0.3.1r give me errors such as:
        ivtv: OSD: DMA xfer from 0xb7efb7d8 of 655360 bytes failed with 
(-512) offset = 0x000b17d0, total 1382352
I noticed that in 0.3.1s a patch was added to fix DMA issues in kernels 
above 2.6.8.  Apparently the stock fedora kernels don't have whatever 
issue was being addressed.

2) The only drivers I have been able to get work with MPlayer's ivtv
patch 
is 0.3.x series.  All other drivers seem to complain about invalid 
arguments to mmap'ing the device and then I get errors about "Error with

sending DMA to ivtv".  This has been mentioned several times before on 
this list without resolution.

3) The mythtv backend (0.16 and cvs) will segfault (without core) after
an 
hour of recording (two 30 minute programs).  I don't think this is 
entirely a fault of mythtv on Core 3.  I have tried debugging the
backend a 
couple of times unsuccessfully, but when I have ... I have caused the
ivtv 
driver to start complaining about ivtv: "ENC IRQ OVERFLOW: #4007
Stealing 
a Buffer, 320 currently allocated"  I think some condition that ivtv is 
creating under Core 3 is unexpected in the mythbackend.  If anyone is 
running mythtv and core 3, please let me know what kernel, driver
version, 
etc you are using.  I will continue to investigate on this end.
