;*************************************************************** ; project name: PCI Device Enumeration ; target platform: KolibriOS ; compiler: flat assembler 1.68 ; version: 2.2 ; last update: December 2007 ; maintained by: Jason Delozier (cordata51@hotmail.com) ; Sergey Kuzmin (kuzmin_serg@list.ru) ; Mihailov Ilia (ghost.nsk@gmail.com) ; Artem Jerdev (art_zh@yahoo.com) ; project site: http://www.coolthemes.narod.ru/pcidev.html ;*************************************************************** ;Summary: This program will attempt to scan the PCI Bus ; and display basic information about each device ; connected to the PCI Bus. ;*************************************************************** ;HISTORY: ;keep dates in european format (dd/mm/yyyy), please ; '!' means big changes ; ;to-do: ; more vendors ; vendor's website ; Subsystem id and Subsystem vendor id detection ; Full device detection (like "ATI Radeon 9200") will increase app ; size a lot and probably it is function of particular drivers ;---------------------------------------------------------------- ;2.2: PCIDEV 03/01/2010 ;Author: Artem Jerdev ;Features: ; fixed ; * English in some comments ;) ; added ; * ! user-accessible MMIO channels detection ; * ! ASCII-dump as PCI memory access demonstration ; optimization ; * (yet needed) ;---------------------------------------------------------------- ;2.1: PCIDEV ??/04/2007 ;Author: Mihailov Ilia aka Ghost ;Features: ; fixed ; * Some little bugs ; * Source code formating ; * PCI version normalized 0210 -> 2.10 ; added ; * + 13 vendor (total now 1000!) ; * + 3 class type ; * Fast call source ready ; * Device IRQ detection ; optimized ; * ! size optimized (61025 -> 32501 see added) ; * easy to add new vendor & class names ;---------------------------------------------------------------- ;2.0: PCIDEV 30/08/2006 ;(it differs a lot from the version 1.0, which was introduced 19 months ago) ;Author: Marat Zakiyanov aka Mario79 ; Sergey Kuzmin aka Wildwest ;Features: ; added ; * Detection of Interface by Mario79 ; * 122 vendor id's by Wildwest ; * Description is based on Class, SubClass and Interface now (PCI 3.0) by Wildwest ;---------------------------------------------------------------- ;1.31: PCIDEV 13/05/2006 ;Author: Jason Delozier ;Features: ; fixed ; * ! bug in Company Name look up code that would cause Unknown Name errors. ; * ! possible bugs, many instructions missing byte, word, dword prefixes ; * ! possible bug which could have occured after removing "PREVIOUSVERSIONLIST" ; entry in loop up code and not fixing jump parameters. ; added ; * comments to various parts of the code ; optimized ; * various parts of the source, too many to remember and mention. ; * changed entries for Subclasses in vendors.inc to Byte format, saves a little space. ;---------------------------------------------------------------- ;1.30: PCIDEV 11/05/2006 ;Author: Sergey Kuzmin aka Wildwest ;Features: ; added ; * 3 new vendor id's (ESS from Madis Kalme and 2 id's ; forgotten from 1.15 release: Broadcom -SiByte and Chaintech Comp.) ; changed ; * I don't know why other devs (Jason or Victor) changed window style ; to old ugly one, so I changed it back to skinned type 3. ; * the same goes to the use of macroc.inc - it is enabled again. ; deleted ; * there is no more label "PREVIOUSVERSIONLIST" - id's moved to the ; appropriate parts of global list. ;---------------------------------------------------------------- ;1.29: PCIDEV 30/04/2006 ;Author: Jason Delozier ;Features: ; fixed ; * ! bug that would not allow devices with device ; numbers > 16 to be displayed. ; added ; * ! another heading called "FNC" (function) which allows ; the multipurpose Device/Function varible to be split and ; displayed to the user properly. ; * horizontal bars to display for easier reading. ; optimized ; * vendor/description search routines for speed and space. ;---------------------------------------------------------------- ;1.25: PCIDEV 02/10/2005 ;Author: Sergey Kuzmin aka Wildwest ;Features: ; changed ; * !
