First, in the code - * itself. A diff between the two version of the driver is now a several - * thousand line diff. Second, in approach to solving the same problem. The - * problem is importing the FreeBSD aic7xxx driver code to linux can be a - * difficult and time consuming process, that also can be error prone. Dan - * Eischen's official driver uses the approach that the linux and FreeBSD - * drivers should be as identical as possible. To that end, his next version - * of this driver will be using a mid-layer code library that he is developing - * to moderate communications between the linux mid-level SCSI code and the - * low level FreeBSD driver. He intends to be able to essentially drop the - * FreeBSD driver into the linux kernel with only a few minor tweaks to some - * include files and the like and get things working, making for fast easy - * imports of the FreeBSD code into linux. - * - * I disagree with Dan's approach. Not that I don't think his way of doing - * things would be nice, easy to maintain, and create a more uniform driver - * between FreeBSD and Linux. I have no objection to those issues. My - * disagreement is on the needed functionality. There simply are certain - * things that are done differently in FreeBSD than linux that will cause - * problems for this driver regardless of any middle ware Dan implements. - * The biggest example of this at the moment is interrupt semantics. Linux - * doesn't provide the same protection techniques as FreeBSD does, nor can - * they be easily implemented in any middle ware code since they would truly - * belong in the kernel proper and would effect all drivers. For the time - * being, I see issues such as these as major stumbling blocks to the - * reliability of code based upon such middle ware. Therefore, I choose to - * use a different approach to importing the FreeBSD code that doesn't - * involve any middle ware type code. My approach is to import the sequencer - * code from FreeBSD wholesale. Then, to only make changes in the kernel - * portion of the driver as they are needed for the new sequencer semantics. - * In this way, the portion of the driver that speaks to the rest of the - * linux kernel is fairly static and can be changed/modified to solve - * any problems one might encounter without concern for the FreeBSD driver. - * - * Note: If time and experience should prove me wrong that the middle ware - * code Dan writes is reliable in its operation, then I'll retract my above - * statements. But, for those that don't know, I'm from Missouri (in the US) - * and our state motto is "The Show-Me State". Well, before I will put - * faith into it, you'll have to show me that it works :) - * - *_M*************************************************************************/ - -/* - * The next three defines are user configurable.
