[Bug 20626] r200 texgen with glVertex4f(x, y, z, w) error
http://bugs.freedesktop.org/show_bug.cgi?id=20626 --- Comment #8 from raoxianhong raoxianh...@163.net 2009-03-16 23:00:52 PST --- (In reply to comment #7) (In reply to comment #6) The problem is solved by update mesa version. But I must DISABLE GL_TEXTURE_GEN_R and GL_TEXTURE_GEN_Q to do it. If GL_TEXTURE_GEN_R or GL_TEXTURE_GEN_Q is enabled, R200 looks line to object coord to normalized (x/w, y/w, z/w, 1.0), it is same when I use with ATI's driver under windows XP, so it must be a limitation of R200. (and I get the same result on RADEON X300, X1300) I'm not sure I follow you there. If you get the same results on X300 and X1300 then possibly the results might be correct. Clearly if you disable GL_TEXTURE_GEN_R and GL_TEXTURE_GEN_Q results are expected to be different. In the example you gave, what coords do you get? The coords after texgen for your four vertices should be (1.0, 0.0, 2.0, 2.0) (1.0, 2.0, 2.0, 2.0) (0.5, 2.0, 2.0, 2.0) (0.25, 0.0, 1.0, 1.0) hence after the q divide (and ignoring the unused r coord) (0.5, 0.0) (0.5, 1.0) (0.25, 1.0) (0.25, 0.0) Is that different to what you get? Note that if you disable some of the texgen coords, the r200 _will_ produce bogus results in some cases, and I think it's generally a good idea to stay away from doing this Oh, I forget the texture coordinates is homogeneous coordinates too, so the texture corrdinates is used with TEXTURE_2D is (s/q, t/q) actually. with object coordinate (x, y, z, w), the s, q texture coord is: s = s1 * x + s2 * y + s3 * z + s4 * w q = q1 * x + q2 * y + q3 * z + q4 * w if we normalized object coordinate to (x/w, y/w, z/w, 1.0) s' = s1 * x / w + s2 * y / w + s3 * z / w + s4 q' = q1 * x / w + q2 * y / w + q3 * z / w + q4 s/q = s'/q' R200 is correct, and you.

[Bug 20679] [i915] blank screen with 2.6.29-rc kernels

Mode switching. When switching modes nearly 50% of times when I come back to X screen is blank. Retry works fine. 100% of switches work. Deattach from dock while system running test. After this X was never blank, but console mode was always. The console mode was perfectly usable. Same as reattach. Reattach to dock. System freeze without stacktrace and the Magic SysRq keys did nothing. All of my reattachment tries has always caused this, and because behavior is so annoying I have done this only three times. Screen is not blank, it is frozen with what ever there happens to be. Input does nothing including SysRq stuff. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Object move evict in new ttm
Hi, Ask ttm to validate buffer from system to vram ttm call driver-bo_move with evict=false which i guess is right as the object will now be in GPU address space. So for the move i need to allocate a temporary GTT space. Here is what i do setup a tmp ttm_mem_reg with numpages=bo numpages call ttm_bo_mem_space to get gtt space ttm_tt_bind it do my dma blit call ttm_bo_move_accel_cleanup with the dmafence So accel_cleanup call ttm_buffer_object_transfer which ref the fence and create a ghost object to hold the previous location. What i don't get is how and when the ghost object is released, so far for me it seems it's never released and so i quickly run with tons of fence object active while already signaled (not mentioning a bunch of ghost object).

To play with R200_TEXGEN_FORCE_W_TO_ONE is not a right way but a useful way sometimes. And sometimes when we disable some of the texgen coords, the r200 produce unexperted results, this maybe we have no right way to generate q coord(for examples, q is zero), but ATI can do it! An acceptable way maybe when user disable texgen Q, driver can enable it on R200, and set q1 = q2 = q3 = 0.0f, and q4 = 1.0f, and set the R200_TEXGEN_FORCE_W_TO_ONE, thus we can get q to 1.0f. it is OpenGL-compliant! -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

[Bug 20626] r200 texgen with glVertex4f(x, y, z, w) error
http://bugs.freedesktop.org/show_bug.cgi?id=20626 --- Comment #13 from Roland Scheidegger srol...@tungstengraphics.com 2009-03-17 18:32:26 PST --- (In reply to comment #12) Yes, I do the same operation under ATI's windows driver, and no problem with disabling texgen R or Q, (and when enable all of texgen STRQ, they looks like not set R200_TEXGEN_FORCE_W_TO_ONE), so I guess they maybe have another way to set q to 1.0 when disable texgen Q. To play with R200_TEXGEN_FORCE_W_TO_ONE is not a right way but a useful way sometimes. And sometimes when we disable some of the texgen coords, the r200 produce unexperted results, this maybe we have no right way to generate q coord(for examples, q is zero), but ATI can do it!

Maybe I'm missing something, but I fail to see how that can work. If you set R200_TEXGEN_FORCE_W_TO_ONE how can the result be correct if the incoming vertex w is != 1.0? I think that basically would just eliminate the w divide which can't possibly be correct. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

[Bug 14967] Kernel hardlocks on X startup
http://bugs.freedesktop.org/show_bug.cgi?id=14967 --- Comment #1 from Ben Skeggs skeg...@gmail.com 2009-03-17 20:38:38 PST --- Did you still have this issue? Those lines haven't been added back in, I'm not certain why they'd be necessary either. If you still have the issue can you post kernel logs (with drm module loaded with debug=1) and Xorg.0.log. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Oh, It looks like we can't find a way to disable textgen Q on r200 and set q to 1.0f, using R200_TEXGEN_FORCE_W_TO_ONE can only provide a way to control texture coordinate for special task, but not an OpenGL-compliant way. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
