What exactly needs approval?  The current license, or are you
proposing a change to the license?

As far as the tiny bit of code that I have contributed is concerned, I
am happy for it to be under MIT/X11, BSD, LGPL or GPL.  Your
choice. :)

Paul.

dropped polygons on savage

I find that the current savage snapshot (20050430) seems to randomly
drop individual polygons or polygon strips (they become transparent to
background). Hardware is SuperSavage/IXC (IBM Thinkpad T23) on FC3/linux
2.6.11.2. 

Testcase: Aviascene  http://69.5.151.193:81/~sdh4/aviascene (problem is
most severe with texturing off (press t))
Screenshot: http://69.5.151.193:81/~sdh4/savagebug.png

Problem did not occur with 20041108 snapshot or prior, or with direct
rendering disabled, or with other DRI drivers. 

Rerendering a frame a second time gives exactly the same polygons
dropped as in the original render. 

	Thanks,
	Steve

Just wanted to confirm that everyone is ok with MIT/X11 license.
It was never explicit before - my fault, I was having too much fun playing 
with the code :)

I always thought it was explicit, at least for me - I didn't just copy&paste 
blindly ;)
So yes, I'm obviously okay with that license.

Do what you want (use any licence you want) with few rows I added.

I noticed this sometimes too, but I was never able to reproduce it
reliably. Does the problem go away if you set the enable_fastpath option
to false?

Lots of changes have occurred in the driver since 2004. It can't be a
DMA problem because the driver can't use DMA on SuperSavages. The
fastpath is my next suspect (see above).

That's good, makes the problem slightly easier to debug.

Re: dropped polygons on savage

Nope. Toggling that option back and forth does not change things. 
The synchronize graphics hardware and floating point depth buffer
options don't seem to do anything either. 

I have a modified testcase that reproducibly generates the same dropped
polygons (on my hardware) every time it's run and without user
interaction:
http://69.5.151.193:81/~sdh4/aviascene_savagebug.tar.gz
( type 'make' followed by 'aviascene castle_demo.cfg' )

R300 licenses


Hi all,

     Thank you very much for your responses :)

        * I modified the readme for r300_demo program to explicitly
          state that the code there is public domain

        * I have added a "LICENSE" file to the r300_driver specifying
          which license apply to which code.

          The r300_regs.h file appeared to be triple-licensed (BSD, GPL,
          MIT/X11). It might be a good idea to make it public domain -
          does anyone have any objections ?

        * I would like to make glxtest code public domain as well - please
          comment.

                     thank you !

                         Vladimir Dergachev

PS I am not a lawyer, so feel free to improve the wording.

Attached offensive beast does this.
When compiled r300_tnl_switch.so is loaded with LD_PRELOAD, applications that use events to read
keyboard input respond to F11 and F12 keys.

need help writing driver for SiS m650

well since there is no DRI support for the SiS m650, and according to
what I heard there never will be, I have decided to write my own. I
have never written my own driver before, and I'm a little confused as
to where to begin. I know that SiS does not normally distribute there
hardware specs, so i might end up having to reverse-engineer the
windows drivers. any advice on where to start for this sort of thing?
and if i were able to get the info from SiS, what exactly would I
need?
