Howdy.
** Background
I've posted a few times about stuttering video on my M10K setup using XvMC. Since I didn't have the problem without XvMC, just video tearing, I assumed XvMC was the culprit, and have been spending evenings trying different versions of DRM/XvMC/VIA.
Well, today I went nuts (that's what this has been driving me to) and tried a few different tacks.
First off, this is an EPIA M10K diskless frontend running .18.
First, in case my hub had issues, I put the frontend and backend on a different 5 port hub. Made no difference.
Second, I noticed that video and ethernet used the same interrupt. I used setpci to change the video one, and it would show that it was changed, but when I started X, it attached to the same old interrupt. No go there.
Third, I thought maybe being diskless was causing problems. I took an old laptop drive, copied the otherwise working root image onto it, tweaked /etc/fstab and the root boot option, and fired it up. Booting from disk worked fine, but playing video still had stuttering.
Next, I copied *one* nuv file from the backend to the drive in the frontend, stopped the front end, moved some directories around so myth would think that file was from the backend, and started it up. Worked *flawlessly*. Well, there was one pause immediately when starting up, and two in the last 8 seconds. I'm not at all worried about that.
So I guess I can stop messing with video drivers.
** Questions
Could someone with a working M10K using built in video and ethernet, with a separate backend, provide me with the following info?
What interrupts are your ethernet and video on? (cat /proc/interrupts)
CPU0 15: 1856705 XT-PIC uhci_hcd, eth0, [EMAIL PROTECTED]:0000:01:00.0
What kernel version are you using? (I'm at 2.6.10)
Are you using the "VIA Rhine" ethernet driver? The "Use MMIO instead of PIO" option? (I'm going to try turning off MMIO now)
Any other suggestions?
Thank,
-Michael
