Hi,
I'm trying to figure out my options for dealing with the ivtv DMA timeout
issues. Here's what I typically experience:
- System is fine for a day or so, and then my PVR500 tuners are unusable. My
250 seems to continue working just fine (not sure why).
- At this point, the entire system starts to degrade (things get pretty slow,
VNC sessions cause freeze ups, attempts to watch/record something on one of the
non-operational PVR150 tuners cause hardware freezes, and a reboot is usually
necessary). Not sure how much of this is related to DMA timeout, and how much
is the result of other gremlins in my setup.
- I have the following errors in my logs, which seem pretty typical of other
people's experience with this problem:
/var/log/mythtv/mythbackend.log:
Error: select timeout - ivtv driver has stopped responding
/var/log/messages:
ivtv1: DMA TIMEOUT 00000001
Here's my system:
- I'm running mythtv 0.20.2 on CentOS 5 (2.6.18 kernel) with ivtv 0.10.5 with
an ASUS M2NPV-VM mobo. I used to run FC5 (with the same HW), but rebuilt my box
recently due to frustrations over the frequent EOL of FC releases.
- I have a PVR250 and a PVR500 (2x 150) (ivtv init stuff attached)
Now, I'm somewhat of a linux novice. I've been running mythtv for about 5
years, so I'm not a complete newbie, but have only ever used packages from
apt-get or other established repositories. I haven't ever compiled my own
kernel or anything like that. My only real experience with Linux is setting up
and using Mythtv (e.g. I don't run Linux at work or anything like that).
I see that there's a potential fix to this DMA timeout issue in the 0.10.6
version of IVTV, but I am *really* confused by what my options are for taking
advantage of this fix. I've read through the ivtv mailing list as well as the
mythtv lists, and googled for more info about this. And while I see that a few
people have posted questions about how to ingest this new driver in a
package-based system, I haven't seen an answer that really seems to spell out
the options. So here's what I think my options are for getting rid of the DMA
timeout issues. Any feedback would be much appreciated:
1. Wait until 0.10.6 is stable and available in a package repository (like
apt-get) - I really don't want to do this since it will likely cause massive
instability and WAF pain until such time as 0.10.6 is stable.
2. Somehow remove the current ivtv drivers by using something like yum remove,
and then build/install the 0.10.6 version (using make install with this:
http://ivtvdriver.org/viewcvs/ivtv/branches/0.10.tar.gz?view=tar). Or will
removing the ivtv packages remove much more than just the ivtv driver? If not,
what's the proper way to build and install new versions of this driver and not
screw up all my packages and dependencies?
3. Will this be any better under FC7 and packages from repositories? (I think
the answer is no, but since my CentOS setup has been so unstable, I'm
contemplating a return to the land of Fedora).
4. Is there another way to work around this problem that doesn't require
updating drivers or disabling DMA?
I think #2 is the direction I want to go, I'm just not sure what the proper
steps are. Again, any help would be much appreciated.
