MeeGo on nonSSSE3 x86 Hardware

Update (vljn): Meego and its netbook ux actually works on non SSE/SSSE3 supporting Pentium 4. The issue is that most non ssse3 chipset comes either with a too old intel gfx, or with an intel/amd graphic chipset. Both are not supported out of the box.

This page was inspired by a discussion on #meego (log@21:17) regarding MeeGo support of nonSSSE3 based hardware.

lbt added to the discussions with a timely blog post he had been working on http://mer-l-in.blogspot.com/2010/08/are-intel-subverting-meegocom.html.

Tasks

• Requirements
  • Proof of concept - create prjconf on maemo OBS to build gcc,binutils, rest of core and bring up on x86 hw/vbox/vmware Devices/nonSSSE3/POC
    • objdump --disassemble-all <binary> | grep " \(psign[bwd]\|pabs[bwd]\|palignr\|pshufb\|pmulhrsw\|pmaddubsw\|phsub[wd]\|phsubsw\|phadd[wd]\|phaddsw\) " | wc -l
    • another script to search binaries for instructions, http://www.nerdbert.com/gentoo/analyse-x86
    • results from ali1234 of the packages from 1.0.1 which include ssse3 instructions, http://pastebin.com/hT3B90v4, formatted list http://pastebin.com/eY7xiESS
