Description Ed McKenzie 2001-07-04 13:33:25 EDT
Currently, the graphical installer is exceptionally slow, and a big part of
the reason is that mtrr wasn't enabled in the -boot kernel.  Now that it is
(see bug 47296), anaconda should take advantage of it.

(IIRC, XFree86 3.x doesn't do this automatically for fbdev devices.  I
could be wrong.)
Comment 1 Brent Fox 2001-07-06 14:48:00 EDT
The installer uses XFree86 4 if it can.  I'm not sure whether XFree 4 user mtrr
by default or not.  If it does, then the problem should already be fixed.
Comment 2 Brent Fox 2001-07-10 21:39:09 EDT
Seems like this is more of an X problem than an installer problem.  Changing
Comment 3 Mike A. Harris 2001-07-16 02:43:39 EDT
This is not an X problem.  XFree86 uses MTRR if it is available.  If
it is not available then it is not built into the kernel.  I am reassigning
to the kernel component, however IMHO it is just unneeded code bloat in
the boot kernel.  I'll leave that decision up to the kernel team though.
Comment 4 Arjan van de Ven 2001-07-18 05:27:59 EDT
It's not that big, so I enabled it, as a "feel" speedup of the installer is
worth it imho.

Note: we need /proc mounted for this to actually work. Does the installer have
this ? (I assume so)
Comment 5 Ed McKenzie 2001-07-18 08:21:47 EDT
Yes, /proc is mounted during install.
Comment 6 Arjan van de Ven 2001-08-03 08:10:57 EDT
Does the roswell installer have this ?
(I find it hard to judge on my machines)
Comment 7 Ed McKenzie 2001-08-03 10:08:53 EDT
I'll install roswell this weekend and report my findings here.
Comment 8 Ed McKenzie 2001-08-04 17:55:38 EDT
Roswell is better.  Scroll views no longer suck. :)
