Notes about VK_EXT_custom_resolve
Vulkan 1.4.333, released on November 14th, includes VK_EXT_custom_resolve, an extension that is closely related to the work we have been doing at Igalia to help Valve release the Steam Frame. It’s an extension that allows you to use a custom fragment shader to specify how to resolve a multisample image into a single-sample image, typically so the latter can be presented on screen. CTS tests for that extension were written by yours truly in close collaboration with Turnip developers, and are now public.

Growing up in the 1980s, I spent countless hours in front of a Commodore 64, and later an Amiga, absolutely mes…
Еще один самодельный компьютер. Coolsystem — Часть 1
Сегодня мы будем делать еще один восьмибитный компьютер. Да, я еще не наигрался со всеми этими штуками.
Coolsystem - идея компьютера, сочетающего в себе идеи о защищенной среде выполнения (причем в очень-очень специфичном варианте) и способного запускать готовый софт для восьмибитных персоналок 80-х годов. Также он может использоваться для изучения основ схемотехники, своего рода учебный компьютер.
