Rather than create a thread I figured this is our official 'fglrx discussion thread'
I'm curious what the "overall current stability level" is with these drivers with the 7870 ish cards
. Life story below.
Back around 2007 I had an ATI 3870HD. The windows drivers sucked. I got so fed up with windows in general and my skill level / needs changed a good bit then, so I decided to jump to linux full time. Back then the fglrx driver sucked even worse. I would get random system lockups about once a week (to the point where even alt+sysrq+b did nothing), chvt never worked, s2ram never worked, and on and on. Suffice to say at the time the fglrx driver should't have even been publicly available. I wasted so much time trying to fix this, but ultimately it was crap code underneath.
So I looked at some nvidia cards, and the nvidia-drivers were worlds ahead. All the stability issues were gone, by and large the nvidia-drivers worked just about as good as the windows versions over in linux. Life was good and I vowed never to run an ATI card again. This is where it gets weird...
Now again my needs have changed, and I need to have a full time windows machine available for others in my household, work (
), and also some testing purposes. I've been using windows guests under KVM, but the graphics performance is a joke. So, now I find that you can pass a full on PCI card to guests and have near bare metal graphics performance. The nvidia cards I have do not support this type of passthrough. I've picked up an ATI 7870 for the guest, and the passthrough works (almost) perfectly with KVM. But, KVM currently has some limitations where if you shutdown the guest with the passthrough card, try to boot it again and your host locks up.
The XEN hypervisor does not have this problem. So I'm trying to migrate over to XEN, but of course Murphy is always around the corner, and XEN does not get along with the nvidia-drivers. The dom0 with the nvidia card effectively has 0 3D acceleration. I assume the domU with the ATI card will work fine when I get to that point shortly.
So my options are:
1) use noveau for dom0 (will test, but not really that interested)
2) pick up another 7870 and use fglrx under dom0, which supposedly works fine, well, as good as fglrx normally works. This is really my main question behind making this post.
3) just build a second computer for windows and forget this whole messCliff notes: If I go buy a 7870 for linux usage with fglrx today, will I regret this decision, or will I have pretty good stability?Edited by lloyd mcclendon - 3/15/13 at 2:51pm
