Surface runtime projecting Pure views across pixel, terminal, CLI, and web. http://git.yeowoo.org/vega/atom?h=master 2026-09-27T13:59:54Z 2026-09-27T13:59:54Z eunhhu necpition205@gmail.com 2026-09-27T13:59:54Z urn:sha1:5313285bbfedf6154d2611c4923cff458d7ef271 vega display draws the same frames on a display with the kernel's mode setting and no library between: a connected connector's mode on a CRTC, its primary plane flipped between two dumb buffers by atomic commits, the grid as many cells as fit. Frames are drawn in cached memory and copied over, since blending over write-combined buffers read them back slowly (a 1080p frame took 370 ms; now 20.6 ms with a vertical sync and the check below). This Pi has no screen but its display controller has writeback connectors: --writeback sets a mode on one and takes every frame back as the controller put it out. Each came back exactly as drawn, and the new check finds it the pixel surface's frame for the same grid, pixel for pixel.
