the dri implementation doesn't pass throgh normal X protocol.. 
for improve the performance, an x application that use the 3d direct rendering 
goes directly to the hardware without passing through a x protocol encorer.
the dri can use the dma to  access the memory of the local machine...

Hi,
  Is there a small, gentle, safe program which prods the /dev/3dfx device
and tells me all the information it can from it and then, under careful
supervision tries simple writes and things to check they work?

(Running my patched Glide on /dev/3dfx on my Alpha causes a system crash,
so I want to try something more gentle).

Here's the situation...  I have two computers, one with a VooDoo3
2000 (at work) and one with a VooDoo3 3000 (at home).  Both have the DRI
built from cvs as of yesterday afternoon.  I'm at work now, logged into my
machine at home.  When trying to run gl applications on my display at
work (but running off my machine) the application dies with the following
error:

X Error of failed request:  GLXUnsupportedPrivateRequest
  Major opcode of failed request:  148 (XFree86-DRI)
  Minor opcode of failed request:  0 ()
  Serial number of failed request:  13
  Current serial number in output stream:  13

This happens no matter what gl app I try to run.  Sometime the serial #
is 13 and sometime 19 (those are the only ones I've noticed).

	I'm not sure if this is a known problem, but I haven't seen any
reference to it anywhere, so I thought I'd pass it along.

i've downloaded the lastest cvs, and after compiling everything i try to run
the server with a voodoo3.

at the startup it dies saying:
(II) Softbooting the board(through the int10 interface)
(EE) Cannot map V_RAM
(WW) softbooting the board failed.

i think that the problem is that i'm not loading the modules tdfx.so, which 
handles the drm shared memory.

it's right?

so i try to load the modules in
xc/programs/Xserver/hw/xfree86/os-support/drm/kernel
i can compile it without problem, but when i try to insmod, it says that
the modules was made for linux-2.2.14 (?????) and not for 2.3.43

so i try to load the tdfx.o module from the kernel distribution, but the result was the same.
(it's the same module? which i -must- use?)

bye!

Hi,

	I am new to this list. I need a overlay
Flip support for displaying video. Does dri have 
this facility for any card.
