When Mesa 10.4 will be available for 14.04?
Hi - I believe the current plan is to release the 2014-Q4 stack for Ubuntu 14.10,
so we're not going to try and land Mesa 10.4 on Ubuntu 14.04.
The general policy is that we try and release the most recent Intel Graphics stack
for the most recent release of a supported distribution that will benefit from it (the
last release, for example, could have been targeted at 14.10, but 14.10 was already
pretty much at the same point as the 2014-Q3 release, so we went for 14.04 instead).
This time around, the Intel stack has moved on enough that it's worthwhile targeting
14.10, so that's where we're aiming this time.
I have to disagree with your policy. You are supporting latest release (which is supported only 6 months by Canonical) and not current LTS which is supported for 5 years and which 99% of users use. There is no logic in doing that.
If old kernel in current LTS is the problem, can you atleast provide ppa with latest drivers? Like this ppa (not supported anymore) : https://launchpad.net/~glasen/+archive/ubuntu/intel-driver
In addition to that ppa users could get newest kernel from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/
And that way we could easly have latest drivers in LTS :)
The LTS is supported for 5 years, but the graphics stack from intel is a
fast moving target. As each release comes out, the version skew between
the two becomes more and more severe. More and more packages get
pulled in as dependencies. There are ABI breaks. It becomes harder and
harder to provide a reasonable update which won't break lots of software.
As for "providing the latest driver", the driver _is_ part of the kernel.
We backport the driver if possible, but after a certain amount of time
(roughly three minor versions worth, usually) the changes are simply
too far reaching for a backport to be possible.
If user gets a recent kernel from the ubuntu kernel PPA, they are already
getting the latest driver: If they have a kernel that is too old, we can't
backport the driver to it.
Thank you for the explanation.
