Optimizacija zagona operacijskega sistema GNU/Linux na vgrajenih sistemih

Medved, Tadej (author), Bulić, Patricio (mentor)

Problematika diplomskega dela zajema optimizacijo zagona in vzpostavitev razvojnega sistema (ang. toolchain) za gradnjo GNU/Linux OS. Zadevo je potrebno raziskati s stališča strojne ter programske opreme. K problemu pristopimo tako, da zgradimo vse elemente, ki so potrebni za zagon GNU/Linux OS z ničle, torej iz izvornih datotek dostopnih prek uradnih sistemov za nadzor izvorne kode. Na takšen način si zagotovimo največ svobode pri apliciranju optimizacij. S takšnim pristopom in optimizacijami, opisanimi v diplomski nalogi, lahko čas zagona na konkretnem Avnet ZedBoard vgrajenem sistemu zmanjšamo z začetnih 35 sekund na 1 sekundo.

• Title: GNU/Linux Boot Time Optimization for Embedded Systems

Abstract

The thesis' problematic requires that we optimize boot time of GNU/Linux OS and establish a building environment for building GNU/Linux OS. Research from a hardware and software perspective is required. We approach the problem by building all of the elements of GNU/Linux OS boot from zero, that means from source files fetched from official source version control systems. This way we get maximum freedom for applying optimizations. With this kind of approach and boot optimizations described in the thesis, boot time can be, on an actual Avnet ZedBoard embedded system, reduced from 35 seconds to 1 second.
