<p>Mesa was upgraded to 10.3, then 10.4 for FreeBSD 10.1-RELEASE and
|
||||||
|
11-CURRENT. We test release candidates and therefore this port is
|
||||||
|
now usually updated shortly after a new release. Mesa 10.x brings
|
||||||
|
huge improvements in terms of OpenGL standards support, performance
|
||||||
|
and stability, especially for Radeon owners. Mesa 9.1 is kept for
|
||||||
|
FreeBSD 9.x, but we have plans to fix this; see below.</p>
|
||||||
|
|
||||||
|
<p><tt>graphics/gbm</tt> and <tt>devel/libclc</tt> are new ports used
|
||||||
|
by Mesa to implement OpenCL. The next step is to finish the port for
|
||||||
|
Mesa's libOpenCL.so, named Clover. This will permit users to run
|
||||||
|
OpenCL programs on Radeon GPUs for now.</p>
|
||||||
|
|
||||||
|
<p>xserver was upgraded from 1.12 to 1.14. This is the last version
|
||||||
|
of xserver supporting Mesa 9.1. Changes are described in an article
|
||||||
|
on the blog. The most noticeable one is probably the switch from
|
||||||
|
the input device detection back-end based on HAL to the one based on
|
||||||
|
devd. hald(8) is still required by many desktop environments, but
|
||||||
|
the X.Org server itself is free from it.</p>
|
||||||
|
|
||||||
|
<p>xserver was the last port supporting the <tt>WITH_NEW_XORG</tt>
|
||||||
|
knob. The knob is now completely removed. This was the occasion to
|
||||||
|
add <tt>WITH_NEW_XORG</tt> and <tt>WITH_KMS</tt> to the list of
|
||||||
|
deprecated knobs to help people clean up their <tt>make.conf</tt>.
|
||||||
|
At the same time, the new-xorg alternate pkg repository was
|
||||||
|
deprecated.</p>
|
||||||
|
|
||||||
|
<p>After discussion, two patent-encumbered options were enabled by
|
||||||
|
default:</p>
|
||||||
|
<ul>
|
||||||
|
<li><tt>TEXTURE_FLOAT</tt> in graphics/dri, which allows Mesa to
|
||||||
|
advertise the support for OpenGL 3.0+;</li>
|
||||||
|
<li><tt>LCD_FILTERING</tt> in print/freetype2, which enables the
|
||||||
|
subpixel rendering engine, improving font anti-aliasing.</li>
|
||||||
|
</ul>
|
||||||
|
<p>These two packages now provide a better user experience
|
||||||
|
out-of-the-box. Users who are uncomfortable with the options may
|
||||||
|
unset them and rebuild the ports. There is no need to rebuild
|
||||||
|
anything else.</p>
|
||||||
|
|
||||||
|
<p>On the kernel side, Tijl Coosemans added AGP support back to the
|
||||||
|
TTM memory manager and therefore to the Radeon driver. His work was
|
||||||
|
merged back to stable/10 and will be available in FreeBSD
|
||||||
|
10.2-RELEASE.</p>
|
||||||
|
|
||||||
|
<p>We migrated our Ports development tree to Git and GitHub. Tracking
|
||||||
|
changes in the official Ports tree and preparing patches is way
|
||||||
|
easier. Furthermore, we can accept pull requests. All reasons behind
|
||||||
|
this change are detailed on the blog and the workf-low is described
|
||||||
|
on the wiki.</p>
|
||||||
|
|
||||||
|
<p>The XDC 2014 (X Developer's Conference) was a great conference.
|
||||||
|
Reviving the relationship with the developers of the graphics
|
||||||
|
stack was a success! A report is available on the blog.</p>
|
||||||
|
|
||||||
|
<p>Our next items on the roadmap are:</p>
|
||||||
|
<ol>
|
||||||
|
<li>Provide FreeBSD 10.1-RELEASE's i915 driver to FreeBSD 9.x users
|
||||||
|
through a new port. This is a work in progress, but it would allow
|
||||||
|
us to remove Mesa 9.1 and make Mesa 10.4 available everywhere.</li>
|
||||||
|
<li>Once Mesa 9.1 is gone, we can update xserver to 1.16.</li>
|
||||||
|
</ol>
