Re: GSoC project: KMS driver for Cirrus Logic graphics
2015-05-11 4:59 GMT+02:00 Damien Miller d...@mindrot.org: Possibly dumb question: why the Cirrus CLGD 5446? It doesn't seem like a very common chipset. Is the goal of the project to have a model KMS driver and documentation that can serve as a guide? Or a KMS driver that works well in a common virtualisation environment? or something else? Not dumb at all, in fact you're right twice. Having a model KMS driver seems important to make easier the future addition of new KMS driver for other graphics chipset. In the same time, being able to testing it from a common virtualisation environment will allow developer to test it and possibly hack it to understand better how KMS works, regardless the hardware they have. In addition, that may allow more KMS-specific testing through QEMU if needed, for other parts of OpenBSD (from framebuffer console to Xenocara).
GSoC project: KMS driver for Cirrus Logic graphics
Hi @tech, I don't want to spam on this mailing list, but it seems interesting to share with the other developers about the content of my project for OpenBSD during the current GSoC. Just to present myself briefly, I'm student in first year of Master in computer science, in Toulouse, France. The goal of the project is to port the current Cirrus userland driver from X.Org to an OpenBSD KMS driver, and to document the process in order to make easier the addition of new KMS drivers for various graphics adapter. As QEMU emulates a Cirrus CLGD 5446, this card is virtually one of the easiest to find for testing purpose, is relatively well documented, and is simple compared to latest intel or radeon cards. For these reasons it's a pretty good candidate to be used as a sample implementation of DRM/KMS. The original proposal contains other informations, mainly non-technical, but if you want to read it I made it available at this address: http://lab.knightsofnii.com/kristaba/gsocproposal/blob/master/README.md Feel free to contact me if you have any question or advice concerning my work (or any other reason). Regards, Léo Grange
