====== Session on ABI emulation ======

This page is from 2015.

===== Linux emulation =====

==== Targeting FreeBSD 11.0 ONLY ====

  * Centos 6.6 32 bit implemented:
    * to be tested with Linux tool suite test
  * Centos 6.7 32 bit in the works
  * Centos 6.7 64 bit in the works (%%CentOS%% 6.6 64bit review: [[https://reviews.freebsd.org/D1746]] )
  * epoll (enhanced polling) implemented
  * Resources required for implementation of Centos 7 and Fedora 22 ports bases/userlands

==== Known issues against WantedLinuxApps ====

List here: [[/WantedLinuxApps|WantedLinuxApps]]

  * Dropbox: impacted by inotify
  * Steam: delayed by PI futexes
  * Skype: working on 11.0-CURRENT, some issues with limited frames per second
  * libaio: impacted by lacking io_setup syscalls
  * Google Hangouts: impacted by closed sourceness, and probably lacking USB libraries/syscalls

==== Issues to be identified for the following applications ====

  * Oracle Client/Server >= 11
  * Android adb/fastboot
  * Acrobat Distiller (not %%AcroRead%%)
  * Spotify
  * Altera Toolchain
  * Xilinx Toolchain

Docker tools ported to %%FreeBSD%%, under Linux emulation 64 bit emulation %%FreeBSD%% 11.0

===== CloudABI =====

==== Work done (Ed Schouten) ====

  * UMTX implementation
  * uploaded into %%FreeBSD%% 
  * %%CloudABI%% applications (toolchain)
  * uniform configuration language/tool (%%CloudABIrun%%)
  * Upstreamed libc++ changes.

**%%FreeBSD%% community feedback welcome!**

==== Work to be done ====

  * Have a package manager for standard libraries.
  * Design cluster management/orchestration system for running %%CloudABI%% processes at a large scale

===== Cheri ABI =====

==== Work in progress for MIPS ====

  * sys calls layers
  * kernel capabilities (conversion into pointers)
