The TTM memory manager

A general overview and an update on graphics memory management in the kernel
K.4.401
Christian König
TTM is the memory manager in the Linux kernel used by graphics drivers with dedicated VRAM. It was added to the mainline kernel in June 2009 and has seen numerous changes and we are now more or less running into a dead-end with it's design. This talk outlines TTMs current functionality, what design problems we ran into and what can we do to fix this.

Although KMS/DRM can replace the Linux Framebuffer, there are a number of programs and libraries that can be built on top of the Linux Framebuffer (without X11 or Wayland dependencies) and that might still be worth considering. The Linux Framebuffer allows direct access to pixels: we will illustrate it with various rendering tools (Fbpad, Fbi, NetSurf, MPlayer, ...), but also with drawing libraries such as Cairo or Evas, and multimedia frameworks like FFmpeg or GStreamer. The Mesa 3D project ...

Automatic, pattern-based code generation for Mesa's compiler infrastructure has been a long standing dream. Nearly a decade ago experiments were conducted using systems like BURS and lburg. Each of these attempts encountered various insurmountable road blocks. In the intervening years, both software and GPU architectures have changed significantly. These changes have enabled a code-generator generator to be a reality. The design and implementation of one system will be presented. In addition to ...
