dans mes recherches sur le forum, je n'ai rien trouvé concernant directement le projet GATOS. Je me lance donc dans l'élaboration de cet humble topic
 
GATOS n'est ni une petite ville de californie, ni une énième orthographe de recette de cuisine. GATOS est un projet visant à améliorer l'accélération 2D et 3D des cartes ATI sous linux. Cette action est concrétisée par l'élaboration de plusieurs pilotes spécifiques à plusieurs cartes de la marque canadienne qui remplacent les pilotes habituellement fournis avec le module d'accélération XFree86.
 
Voici la liste des cartes et surtout des processeurs graphiques supportés :
 
All-in-Wonder classic (Mach64)
    Should work fine with either 4.1.0 or 4.2.0 drivers. Both XvImage (YUV->RGB overlay and scaling) and TV-in should work fine. There were success reports with NTSC, PAL and SECAM standards. Video capture should work as well.  
All-in-Wonder Rage128 16mb (Rage128)
    Should work fine with either 4.1.0 or 4.2.0 drivers. Both XvImage (YUV->RGB overlay and scaling) and TV-in should work fine. There were success reports with NTSC, PAL and SECAM standards. Video capture should work as well. At the moment video capture (km) is incompatible with DRI acceleration.  
All-in-Wonder Rage128 Pro 32mb (Rage128)
    Should work fine with either 4.1.0 or 4.2.0 drivers. Both XvImage (YUV->RGB overlay and scaling) and TV-in should work fine. There were success reports with NTSC, PAL and SECAM standards. Video capture should work as well. At the moment video capture (km) is incompatible with DRI acceleration.  
All-in-Wonder Radeon (Radeon)
    Should work fine with either 4.1.0 or 4.2.0 drivers. Both XvImage (YUV->RGB overlay and scaling) and TV-in should work fine. There were success reports with NTSC, PAL and SECAM standards. Video capture should work as well. 3d acceleration should work fine.  
All-in-Wonder Radeon 7500 (RV200)
    Should work fine with 4.2.0 drivers. Both XvImage (YUV->RGB overlay and scaling) and TV-in should work fine. There were success reports with NTSC standard. Video capture should work as well. 3d acceleration should work fine. Wireless (RF) remote control should work.  
All-in-Wonder Radeon 8500DV (Radeon200)
    Should work fine with 4.2.0 drivers. XvImage (YUV->RGB overlay and scaling) should work fine. TV-in works in NTSC. It is expected that PAL and SECAM will be easy to made working once there are people willing to test and debug TV-in with these formats. Video capture should work. 3d acceleration is not implemented as of this writing. Firewire port (at least the one on the card itself) has been observed to work in Linux. Wireless (RF) remote control should work.  
All-in-Wonder Radeon 9700 (Radeon300)
    We have received documentation for this card and sample hardware (thanks to ATI !), work is underway. At this moment we cannot promise a specific timeframe for availability of working drivers or list specific feature that will be supported.  
Rage Mobility-P (Mach64)
    Should work fine with either 4.1.0 or 4.2.0 drivers. XvImage (YUV->RGB overlay and scaling) should work fine. Video capture should work as well, but typically these controllers are not TV-in capable. Those that are often incorporate SAAxxxx decoder from Philips (IBM Thinkpads, for example) which is not supported at the moment.  
Rage Mobility-M3 (Rage128)
    Should work fine with either 4.1.0 or 4.2.0 drivers. XvImage (YUV->RGB overlay and scaling) should work fine. Video capture should work as well, but typically these controllers are not TV-in capable. Those that are often incorporate SAAxxxx decoder from Philips (IBM Thinkpads, for example) which is not supported at the moment.  
Radeon 64mb: XvImage
    Should work fine with either 4.1.0 or 4.2.0 drivers. XvImage (YUV->RGB overlay and scaling) should work fine. Video capture should work as well, but this card does not have any TV-in ports.
 
Mes compétences sommaires dans la traduction de la langue de Shakespeare m'interdisent toute action en ce sens. J'espère que vous comprendrez vous même. Si une personne est assez aimable et compétente, qu'elle me fasse signe. La première qualité étant somme-toute pas indispensable
 
Installation
 
Plusieurs distributions sont disponibles, comme d'habitude dans le monde du logiciel libre. Sous forme de RPM tout d'abord ; sous forme de sources ensuite.
 
Vous trouverez tout sur cette page.
 
Aujourd'hui, ce qui me manque, c'est une description concise de ce qui se passe lors de l'installation de ces pilotes et quelle est la démarche d'installation. Même si pour certains les quelques phrases trouvées sur le site suffisent à leur bonheur, j'avoue rester sur ma faim ...

une autre chose : comment savoir que c'est effectivement le pilote GATOS qui est pris en compte au redémarrage de X ?
