#333 closed defect (Unsupported Version)

AMD Chipset, Todo

Reported by: eco Owned by:
Priority: major Milestone: Release version 3.19
Component: ACPI PSD Version: 3.11
Keywords: Cc: ecslist@…

Description

First of all, Pasha made the research, AMD chipset problems are note related to ACPI.PSD. If you enable ACPI then the PC behaviour changes.

Pasha offers two ways to support AMD-chipset:

  • in new kernel
  • via Bootable JFS

To integrate Bootable JFS to eCS I have spent 2 years (?), it is debugged, it is there, so..

we should select BooJFS method (via BooJFS booter). Users need solution for commercial usage, for productivity usage today. It's transparent if implement support of AMD via BooJFS.

LightElf? offered:

use PhysToVirt? helper

Load drivers to video memory

Usually it's necessary load 1.5 Mb of files

How to calculate free video memory start?

  • VESA BIOS - query LFB base address, ignore the first 8-16 Mb of memory, use all other memory.
  • or query via PCI BAR with Prefetch bit,

AMD chipset => computer was manufactured in 2008 => Video adapter has more than 64 Mb, 128 Mb.. usually 1 Gb of memory.

  4. ограниченое количество 16 бит селекторов

если вы готовы оплатить полгода непрерывного траха с этим бутом, то могу с понедельника приступить более окромя бута я ничем заниматся не буду

ENG: there are restrictions, Pasha requests 1/2 of year to implement the method.
