Dave,
So I tested the (git from last night 5/10) the latest code
(x+mesa+drm) on my RS480
In general, things are MUCH better, but I was running through the
sample programs in Mesa, and I found some remaining issues. I ran the
tests on fglrx, took some screenshots, and compared them to the R300
results.
I've included the details below, but is bugzilla the best place to put
this info?
Cheers,
--Phil
I ran some of the Mesa samples in: '/progs/samples'
Visually Identical:
accum, blendeq, depth, star, stencil
Minor Problems:
line:
R300 is not pixel identical to fglrx, but they generally look the same.
nurb:
R300 is not pixel identical to fglrx, but they generally look the same.
olympic:
R300 is not pixel identical to fglrx, but they generally look the same.
bitmap1:
fgrlx seems broken.. 'GL' is not shown in the middle.
tri:
R300 is not pixel identical to fglrx, but they generally look the same.
I did notice that in the R300 version, the color gradient inside box
starts a line below the fglrx version.
I did get this warning:
*********************************WARN_ONCE*********************************
File r300_render.c function r300Fallback line 494
Software fallback:ctx->Line.StippleFlag
***************************************************************************
Major Problems:
logo:
It appears as if the clip plane is completely different, but the
basic geomtery is the same.
point:
On the R300 version, The crosshairs is one pixel lower.
prim:
On the R300 version, The openGL crossharis is one pixel lower
fogtest:
On the R300 version, the end of the tube is not red.
(In the source, the only thing that is red is:
static float back_mat_diffuse[] = {1.0, 0.0, 0.0, 1.0};
glMaterialfv(GL_BACK, GL_DIFFUSE, back_mat_diffuse); )
quad:
On the R300 version, the interior of the cone is not green.
sphere:
On the R300 version, the grid lines are missing, and there is a strip
missing on the cyclinder.
wave:
On the R300 version, the checkerboard is completely missing. If I
turn off lighting, the checkerboard appears.
....
progs/demos:
fire:
On the R300, the trees are corrupt... They're in front of the fire.
cubmap:
On the R300, This has a wierd corruption as it spins.
terrain:
On the R300, This has triangles flying everywhere. ;-)
ipers:
On the R300, Triangles intersect the main geometry.
tunnel:
On the R300, Triangles intersect the main geometry.
