Something to do with a parse error on scsi_queue >at line 1206 of ncr.c. I know. Once I decided to leave the queue work to Stephan, I killed it from the LINT file I used to test that all the drivers compiled correctly. The diffs are only in there to give Stephan an idea of what's needed. >I should be up and running on a 2940U any minute now... anything special >you want tested? [First thing I am going to run is a make world, that >should be done in about 2 hours...] I don't have any particular test cases in mind. I'm mostly interested in knowing if I've created any strange I/O behavior with the new round-robin scheme (especially with multiple targets active). It would also be nice to know if its faster or slower than the old code. As an aside, I'd like to find "owners" for all of the controller and type drivers. I'd like to complete a comprehensive review of the entire SCSI system before 2.2R ships, and we'll have to split up the work in order to make this an achievable goal. Even if we simply create a list of who has the documentation for which cards, that would be a start. >-- >Rod Grimes rgrimes@gndrsh.aac.dev.com >Accurate Automation Company Reliable computers for FreeBSD -- Justin T.
