Building and Testing an Automotive Platform – How Automotive Grade Linux is Built and Tested
Building and Testing an Automotive Platform – How Automotive Grade Linux is Built and Tested – Jan-Simon Moeller, The Linux Foundation
Ever since Linux started running on embedded devices, having a swap for such had been considered a misconfiguration rather than a method for overcoming RAM shortage or performance booster. This attitude started to change with the spread of Android devices which usually don’t have a problem utilizing virtually any amount of memory. An with the introduction of ZRAM the usage of a compressed swap in RAM became more useful and more popular. This talk will give a comprehensive description of ZRAM and its counterpart, zswap, a summary of pro’s and con’s of both. This talk will also cover a brand new z3fold compressed memory allocator which can be used for both zswap and ZRAM, of course presenting measurement results for these, obtained on various devices, ranging from set top boxes to laptops, not to forget Android phones.
