Currently, the cube plugin uses mipmapping only when cube is unfolded. When the cube is rotated, mipmaps are not used, which leads to ugly look of textures. The attached patch fixes this. This leads to another kind of artifacts, which are fixable with anisotropic filtering. http://team.pld-linux.org/~wolf/aniso.png The leftmost image...

I'm currently implementing mipmaps but I have a set of troubles guessing the block height and block depth of them. According to https://envytools.readthedocs.io/en/latest/hw/memory/g80-surface.html#textures-mipmapping-and-arrays the texture unit auto resizes mipmaps' blocks but how do I know how many blocks each one uses? I...

This patch fixes two issues in nv40_miptree_layout. First, pt->width0 is used, which is the size of the whole texture, while width, which is the size of the mipmap level, should be used. Second, the current code does not 64-byte align the pitch of swizzled textures. However, on my NV40 this causes a pgraph error regarding the pitch register (and sometimes a system lockup too), which is fixed by this patch. I'm not sure how small mipmaps could have worked...

Make sure to normalize the z coordinates as well as the x/y ones when there are mipmaps present. Fixes 3d mipmap generation, which now uses the blit path.

Hello, I have been looking at cubic texture mapping for a bit, and I have found that hw mipmap generation doesn't work at all or the textures are all messed up (normal 2d work fine). This is with linear textures. Also of note is that software mipmap generation works fine. I have done sanity checks for the miptree pitches, offsets, etc and everything seems to match up fine for both...

...it seems to break compiz which errors out complaining that there are no GLXFBConfigs for the default depth. I was able to trace the problem to the following block of code in src/screen.c, starting on line 1897: if (s->fbo) { (*s->getFBConfigAttrib) (dpy, fbConfigs[j], GLX_BIND_TO_MIPMAP_TEXTURE_EXT, &value); if (value < mipmap) continue; mipmap = value; } From what I understand the contents of the if block where never executed when running with the i915 DRI module because it didn't support FBOs. The problem with the new i915tex module is that FBOs are supp...

I'll check that once the 2D code is otherwise finished and working * Swizzled 1D/2D/3D textures Mipmaps are laid sequentially with no gap in between. Each mipmap is laid "swizzled". To get the swizzled address of a texel, take an x bit, then an y bit, then a z bit and so on. If you exceed a dimension, skip taking their bits. This means in particular that 3D textures are "3D swizzled&q...

Hi Why is the quality of scaled textures/objects using --indirect-rendering much worse than direct rendering? Also, vsync does not work with indirect-rendering. I am using an Nvidia Geforce go 7300, with 97.55 drivers. Thanks, Matt

Hi guys again. A homebrew developer (homebrew is custom software made for the switch using openGL under nouveau) reported to me that 'glGenerateMipmap' wasn't working on yuzu (Nintendo Switch emulator). I looked into it and I noticed all the triangle data used by nouveau to render the mipmaps was all zeroed out, meaning that probably we don't implement the mechanism you guys use to upload that data. How can I track this in your code...

...led according to my testing. The miptree layout is rewritten based on my empirical testing, which I posted in the "miptree finding" mail. The image_offset array is removed, since it can be calculated with a simple multiplication; the only array in the miptree structure is now the one for mipmap level starts, which it seems cannot be easily computed in constant time. Also, we now directly store a nouveau_bo instead of a pipe_buffer in the miptree structure, like nv50 does. All the deletions are due to the nv04-nv40 unification. Support for render temporaries is removed, and will be read...
