There are two major package classes in Fedora that provide graphics
drivers: xorg-x11-drv-*, and mesa-dri-drivers-*.
In F15, mesa-dri-drivers now only includes drivers with DRI2 support
(radeon, nvidia, intel) and the software renderer; if you want all the
older drivers you have to install mesa-dri-drivers-dri1. This list is:
i810, mga, r128, savage, sis, tdfx, unichrome
Basically all of this hardware is, ahem, inept. The most featureful
device supported by these drivers would be the MGA G550, which just
barely manages to do DirectX 7 (comparable to a Radeon 7000 or GeForce
2, both ~1999 vintage). All the others are back in the DX6 stone age.
For comparison, the baseline for the GPU in the phone in your pocket -
and that platform layers like clutter more or less expect - is GLES 2.0,
which is roughly comparable to DirectX 9. We're rapidly approaching the
point where the software renderer is going to be a more satisfying
experience than hardware 3d support for these chips, both for features
and for performance.
So in my ideal world, we would simply drop the -dri1 subpackage (and for
that matter, DRI1 support in the X server).
For 2D we've got an xorg-x11-drivers metapackage that includes, well,
pretty much everything, and which is included in comps as a default.
This is lame, because it means a bunch of backwater drivers end up as
critical path and can never possibly get tested. (Smolt says there are
all of 3 savage users. I assume the number of i740 users is actually
negative.) The list of video drivers that see any actual use is
probably something like:
ast, ati, cirrus, fbdev, geode, intel, mga, nouveau, openchrome,
qxl, sis/xgi, vesa, vmware
Would this affect the way KVM and specifically qemu-kvm in it's default
setup for video using the cirrus driver would work? Just wondering if
there would be any implications for the virt guys in that regard.
Thanks & regards, Phil
