You will not, I repeat, will not be able to mode switch or anything
non-trivial like that when the kernel is in this state.

Remember also, that being nice to everyone else by sleeping, there are
more cycles to go around, and the scheduler can nicely boost the X
server's priority as it will for interactive processes that are being

Of course, in 1996, XFree86 would have ignored any such interfaces, in
its insane quest for operating system independent user space drivers
requiring no standard kernel interfaces (it is the second part of
this where the true insanity lay).

We're pursuing two courses of action right now, that are not mutually
exclusive.
Jon Smirl's argument is that we can satisfy both needs simultaneously
with a GL only strategy, and that doing two is counter productive,
primarily on available resource grounds.

Certainly replicating OpenGL 2.0's programmability through Render makes
no sense at all to me (or most others, I believe/hope). If you want to
use full use of the GPU, I'm happy to say you should be using OpenGL.

question is should there be general kernel facilities to make this easy
(we did it via ugly hacks on VAX and MIPS boxes) for kernel facilities
to provide.
"X is an exercise in avoiding system calls". I think I said this around
1984-1985.

Exactly why I noted in my mail that I didn't consider it novel even back then; just
a good engineering idea that we went ahead and used a long time ago...

we're in really high volume production (>100K/month) but demand still
outstrips supply (sigh...).

od idea on most embedded systems.
Getting the pages back is a (relatively) cheap operation: no disk seeks,
some joules spent on decompression (if on CRAMFS or other compressed file
system).
There is an interesting question on such devices as to whether you are
better off dropping text pages or pages
g question on such devices as to whether you are
better off dropping text pages or pages out of the page cache first,
or to what degree...

Sounds like one needs in addition some mechanism for servers to "charge" clients for
