It has always bugged me that there was no real interface between fbconsole and fbdev. For example I tried to write a wrapper for DRM so that fbconsole could use DRM for accelerated console. But fbconsole is so tied into the fbdev data structures writing the wrapper required me to build most of an fbdev driver. I shouldn't need to do that, fbconsole should not be poking at fb_info, it should use an API for making changes.Yes. I think I'm planning to do that in small steps. I'm thinking first of separating all fbcon-specific fields and place them in another structure, ie, fbcon_info. This struct will be registered separately from fb_info, and only if fbcon is enabled.Thats why its called the framebuffer console. It used the framebuffer api. Making a API between fbconsole and fbdev would be more bloat and whould have a performance it. The idea is to go as fast as possible.
A few extra instructions implementing an API won't make much of a difference. We can only update the screen 70 times a second or so. Wouldn't it be better to make an API than have me copy fbconsole, rename it driconsole and then edit it to make it work? An API makes the code more maintainable and reusable. -- Jon Smirl jonsmirl@gmail.com ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf
