1bf215546Sopenharmony_ciRandom list of problems with i915g: 2bf215546Sopenharmony_ci 3bf215546Sopenharmony_ci- What does this button do? Figure out LIS7 with regards to depth offset. 4bf215546Sopenharmony_ci 5bf215546Sopenharmony_ci- Dies with BadDrawable on GLXFBconfig changes/destruction. Makes piglit totally 6bf215546Sopenharmony_ci unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still 7bf215546Sopenharmony_ci broken, it doesn't update the viewport/get new buffers. 8bf215546Sopenharmony_ci 9bf215546Sopenharmony_ci- Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason? 10bf215546Sopenharmony_ci Texture sampling from Y-tiled buffers seems to work, though (save above 11bf215546Sopenharmony_ci problems). 12bf215546Sopenharmony_ci RESOLVED: Y-tiling works with the render engine, but not with the blitter. 13bf215546Sopenharmony_ci Use u_blitter and hw clears (PRIM3D_CLEAR_RECT). 14bf215546Sopenharmony_ci 15bf215546Sopenharmony_ci- src/xvmc/i915_structs.h in xf86-video-intel has a few more bits of various 16bf215546Sopenharmony_ci commands defined. Scavenge them and see what's useful. 17bf215546Sopenharmony_ci 18bf215546Sopenharmony_ci- Do smarter remapping. Right now we send everything onto tex coords 0-7. 19bf215546Sopenharmony_ci We could also use diffuse/specular and pack two sets of 2D coords in a single 20bf215546Sopenharmony_ci 4D. Is it a big problem though? We're more limited by the # of texture 21bf215546Sopenharmony_ci indirections and the # of instructions. 22bf215546Sopenharmony_ci 23bf215546Sopenharmony_ci- Finish front/back face. We need to add face support to lp_build_system_values_array and use it in draw_llvm.c. 24bf215546Sopenharmony_ci 25bf215546Sopenharmony_ci- More optimizations, like replacing ADD + MUL with MAD or use DP2ADD. 26bf215546Sopenharmony_ci 27bf215546Sopenharmony_ci- Replace constants and immediates which are 0,1,-1 or a combination of those with a swizzle. 28bf215546Sopenharmony_ci 29bf215546Sopenharmony_ci- Schedule instructions to minimize the number of phases. One way is to replace 30bf215546Sopenharmony_ci R registers responsible for a boundary with U registers to avoid phase 31bf215546Sopenharmony_ci boundaries. 32bf215546Sopenharmony_ci 33bf215546Sopenharmony_ci- Continue a previous primitive when there are no state changes 34bf215546Sopenharmony_ci 35bf215546Sopenharmony_ci- Fix fragment discard 36bf215546Sopenharmony_ci 37bf215546Sopenharmony_ciOther bugs can be found here: 38bf215546Sopenharmony_cihttps://gitlab.freedesktop.org/mesa/mesa/-/issues?scope=all&utf8=%E2%9C%93&state=opened&label_name[]=i915g 39
