21:55 < pmdata> hello
21:56 < pmdata> just tried new stuff, fsaa (using __GL_FSAA_MODE)
21:58 < pmdata> it setup the viewport with bigger dimensions (x1.5, or x2.0) and then only three unknown commands used (208, 2c0, 2e0)
21:59 < marcheu> oh, so your card uses supersampling ?
22:00 < marcheu> unknown commands to what object btw ?
22:00 < pmdata> hum, according to nv readme:
22:00 < pmdata> GeForce, GeForce2, Quadro, and Quadro2 Pro supports 1.5x1.5 and 2.0x2.0
22:01 < pmdata> and yes, this is supersampling from what the readme says
22:02 < pmdata> object is beef5601, and commands related to nv10_tcl_primitive_3d
22:03 < pmdata> if you want to try, just use the draw_pixels test, and make a diff between outputs
22:04 < marcheu> I've got the nv28 plugged in right now
22:04 < marcheu> it does FSAA differently
22:05 < marcheu> I think it simply uses a downscaling during swapbuffers(). I wonder if downscaling also exists on <nv10
22:06 < marcheu> we could do FSAA on TNT :)
22:06 < pmdata> yep, just use bilinear texturing from framebuffer :)
22:06 < marcheu> but what is the nvidia driver doing ?
22:07 < pmdata> hum, I should check how gl_nearest/gl_linear is setup for texturing, maybe they are the same commands
22:07 < marcheu> but does the nvidia driver uses a texture + bilinear filtering to achieve FSAA at swapbuffers() time ?
22:08 < marcheu> or something else ?
22:09 < pmdata> I don't know, the diff only shows the 3 commands with different parameters, and don't forget the videomode/viewport is setup as 512x512 so it can be a direct operation
22:09 < pmdata> I should try 640x480 then
22:13 < pmdata> hum, not much difference

22:18 -!- svu_ [n=svu@194.46.176.245] has joined #nouveau
22:19 < pmdata> I think it setup a 1024x512 framebuffer, and do its stuff from there
22:43 < pmdata> ah, cvs commit: image_from_cpu uses same parameters type as context_clip_rectangle
23:14 < pmdata> added logic ops value to objects, need to print macro from bitfield now
23:14  * pmdata can't wait playing warsow using nouveau driver :)
23:24 < pmdata> can someone explain what could be nvXX_context_surfaces_2d? destination rendering buffer?
23:29 < pmdata> oops, the gl_logic_op array I added may requires special treatment, I sorted in the order 0 -> 15, they are not the values from GL/gl.h
23:42 -!- Lumag [n=Lumag@chimpanzee.school.ioffe.ru] has joined #nouveau
23:44 < Lumag> hi!
23:48 < pmdata> hi lumag
23:56 < pmdata> lumag> should I make an extra print function to print value names from a bitfield? (for gl_logic_op array I just added)
23:57 < Lumag> Hmmm... I think no. You should use print_macro
23:58 < pmdata> print_macro takes bits from 0 to 31, what about a bitfield?
23:59 < Lumag> Not PRINT_MACRO, but print_macro. look at the nv30_tx_format output :)
