----------

it was done with RADEON_DEBUG=tex

 It fails in 8888 formats chooser, but it works for every format in firecube just fine here on rv280 if i leave in radeon_texture.c just one format in that function:

 static gl_format radeonChoose8888TexFormat(radeonContextPtr rmesa,
					   GLenum srcFormat,
					   GLenum srcType, GLboolean fbo)
{
	return _radeon_texformat_argb8888;
}

 Also 'fgl_glxgears -fbo' started to work OK and many other games. For example
frogatto fail to work because of this, now start just fine, etc.

 If someone think this is OK, i can sent a patch to mesa-dev?

Created attachment 72832 [details]
fgl_glxgears -fbo on rv280

Created attachment 72833 [details]
fbo_firecube on rv280

 Checked with piglt fbo tests (current git master) it passes more tests: before patch it is 14/28 and after this patch it is 28/33 . Seems to be nice improvement :).

Nice work!
Please send the patch to mesa-dev

Possibly related to bug 51658.

Does this regress anything in piglit?  It's been a while since I
looked at this code, I think the issue may be that r1xx/r2xx asics
only support ARGB render buffers while the texture hardware supports
both ARGB and RGBA formats so you may run into cases where you can
texture from a buffer, but can't render to it, at least not without an
intermediate blit to convert the format first.

 I am not member on the mesa dev list, so to quick answer here :).

 No, no regress in piglit i've seen at all, only better... i even played whole Drawn 2 game: 
 http://www.drawngame.com/games/dark-flight
under wine in OpenGL mode, it works perfectly now, needs culling under fbo which is fixed now and this fix to display text and so works exactly the same as with nvidia on Windows. 

 It can further pass 2 more test in piglit if those are ported from intel:

 fbo-nodepth-test
 http://cgit.freedesktop.org/mesa/mesa/commit/?id=4d4f2daefabdc4ca1dd778a9265475c65ef52936

 i've tried that one and it pass and maybe this for fbo-cubemap - but not tried: 

 http://cgit.freedesktop.org/mesa/mesa/commit/?id=80513ec8b4c812b9c6249cc5824337a5f04ab34c

 Now i checked supertuxkart game, it has some problems with alpha in XRGB8888 format. Under non-fbo mode kart model have black background, and under fbo models are transparent. I fixed it for non fbo case with R200_TXFORMAT_ALPHA_IN_MAP for XRGB8888 also in r200_blit, but don't know where is this format controled for fbos?  I mentoioned this because text is slightly transparent also in that Drawn game, it only works with with fbo extension in opengl mode, i guess that needs the same fix for XRGB8888 format to expect alpha under fbo, etc... But OK that can be another bug :).

You can post to the list as a non-member, your posts just go through the moderation queue then. Please don't abuse bugzilla like this.
