FFe: Update to 2.6.3

Normally upgrading to a .2 is a no-brainer. However in this case, the upversioned libdrm dependency means we're going to need to do a more thorough review and testing of both packages (and any other dependency changes that result), which will take time.

If we can't take the .2 in its totality, perhaps we can cherry pick patches into ubuntu.

I would change to 2.6.3, since it has been released today.

Same problem.

I've merged and uploaded libdrm 2.4.5 now.

i'm ready to test the 2.6.3 then :)

I put it on my ppa, but it requires a kernel change as well.
So have to wait on kernel team before we get a package.

any update on the kernel? Anyway did you tested the drivers? Do they
work much better?

The kernel received a lot of updates in the last week, but no one got
your patches.
Are you sure the maintainers got your request?

Subscribed ubuntu-release so that we follow the FFe process here.

Bryce, is a summary available of the key changes that carry risk of regression?

Andrea, yes I know for certain the maintainers got the request - I went to lunch with him last week. ;-)

I have a feeling it just slipped off their radar though; I know the kernel team's swamped right now.

I've figured out a simple kludge-around to get it to build (and boot and run) on my hardware. Performance is good on EXA, although I never was able to reproduce the performance issues everyone has been complaining about, so that's just anecdotal. Both compiz and non-compiz seem to work fine.

Going to do a bit more testing.
Meantime, I've pushed up an updated 2.6.3-0ubuntu1 to my ppa if anyone else wants to play with it.

slangasek, brief summary from the release notes:

2.6.2: Here comes a pretty significant bugfix release for the 2.6 2D series.
The goal of this release is to get out the major fixes for GEM and KMS
that we think we've pounded on enough to be stable -- certainly more
stable than previously. Notable fixes include a significant BO memory
usage reduction (which many have suffered from with compositing),
textured XV support with KMS, and rotation support with KMS. Some
infrequent failure to render/xv with GEM on 965 (dmesg warnings about
being unable to bind objects) should also be fixed.

But perhaps the exciting thing for most people will be the dynamic front
buffer allocation. We nearly slipped this into 2.6.0, but decided that
it was just a little too new. Well, turns out it was actually in good
shape, and it's time to get it out there. You'll need UXA to do this.

2.6.3: This is an easy one: two bugfixes for regressions in the last release.
One broke initialization with UXA and DRI1, and the other made pixmap
allocation on i915 take insane amounts of memory.

2.6.3 is now uploaded for testing with -beta.

FFe granted. Let's get this in ASAP so that it's in good shape for beta.

Thanks; uploaded to jaunty.

works fine here

Works well here too.

GMA945 (Dell Latitude D430): UXA still works fine, basically unchanged from previous versions. I still get some fading artifacts in compiz, but otherwise works okay.

EXA still by and large works as well, but I get one regression: When I start glxgears and try to move the window, the original window content is "snapshot" at the old position, and the windows underneath don't redraw. I have to switch workspaces back and forth to repair it.

Bryce,

do we have to wait for an kernel update to get better performance?
In Ioquake3 I get in Intrepid 87 FPS and in Jaunty 11 FPS w/o DRI2. (Resolution 640x480).
compiz is also very slow, not really usable.

Maybe this bug is related to the problem?

@Martin, that glxgears thing is not a regression but rather is the old "no redirected indirect rendering bug" that has been there since we first adopted Compiz, and that DRI2 (and UXA) was introduced to fix.

@Achim, Compiz performance was fine for me when I tested for this upload.

Hi,
I bought a TV last week from a website:www.hkeles.com. I have
received the product. The quality is very good. They also sell
phones,motor,psp and so on. Because of the financial crisis, their
products are very cheap. by the way, they only sell new and original
products .If you need these products, you can have a look . I think
you will get many benefits.
Greetings!
