[PATCH] drm/radeon/kms: add module option for pcie gen2
by Alex Deucher 13 Jan '11

13 Jan '11

Switching to pcie gen2 causes problems on some boards. Add a module option to turn it on/off. There are gen2 compatability issues with some motherboards it seems.

It seems that there is still a regression for intel graphic cards backlight. One report is https://bugzilla.kernel.org/show_bug.cgi?id=22672. I can reproduce the problem easily by: xset dpms force standby; sleep 3s; xset dpms force on backlight doesn't get up (there is really dark picture though which doesn't get brighter by function keys which work normally) after dpms on until I close and open lid.

[git pull] drm intel only fixes

I'm stuck at home with just my i5 laptop due to the office being shut due to the ongoing floods. But I've booted and ran this for a few hours and it seems to be better than the current tree.

[PATCH] drm: Trim the GEM mmap offset hashtab
by Chris Wilson 12 Jan '11

12 Jan '11

Using an order 19 drm_ht for the mmap offsets is a little obscene. That means that will a fully populated GTT with every single object mmaped at least once in its lifetime, there will be exactly one object in each bucket. Typically systems only have at most a few thousand objects, though you may see a KDE desktop hit 50000. And most of those should never be mapped... On my systems, just using an order 10 ht would still have an average occupancy less than 1, so apply a small safety factor and use an order 12 ht, like the other mmap offset ht.
