So this approach probably wouldn't solve Julian's immediate problem. Apart from that, this approach seems significantly better than (effectively) committing diffs to binary files.

This does leave CTM-users the odd men out As Matt pointed out, CVS provides us with a good mechanism for ensuring that I can identify what version of the firmware I am using - and be reasonably certain it matches the code that Matt (or whoever) validated. So would simply naming the files by version. This works because most if not all of our drivers use firmware from another vendor with its own version-numbering scheme. -GAWollman -- Garrett A.

Re: asm_pci.h,v Holy cow!
I don't see the purpose of having a firmware image permanently resident (especially given their sizes). Getting the boot loader to directly load the firmware into the device seems a much nicer solution. If this is impractical, treating the firmware as a kld and unloading it after downloading the firmware would seem the next best option. There's an open PR on this one.

CVS is Not Good at handling binary files (even if you never change them). That's why I'd like them in a separate hierarchy. Actually, CVS1.10 is *MUCH* better at handling binary files, although you must be sure to set them up as binary files. It works cross-platform and such, but if the file is not added as a binary file, it really gets nasty. ;( (Plus all of the size bloating issues, but that's a seperate issue IMO).

asm_pci.h,v Holy cow!
My cvsup appeared to be frozen, so I stopped it and looked.. src/sys/dev/isp/asm_pci.c,v is 13MB long! it was just taking a long time.. this seems a little excessive. anyone got any ideas. (13MB on a 40Kbit link is a long time) to make matters worse cvsup appears to be redownloading some very large percentage of this file whenerver there is a change to it. -- __--_|\ Julian Elischer / \ [EMAIL PROTECTED] ( OZ) World tour 2000 --- X_.---._/ presently in: Perth v To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Re: asm_pci.h,v Holy cow!
Yes, this needs to be fixed. I have an open bug about this with respect to making the f/w a loadable module as well. I'll probably split it into several pieces so that each f/w update is smaller. I could probably make it binary and compress is (each f/w module is an array of 16 bit shorts), but that has it's onw problems. You should note, btw, that my link isn't all *that* faster than yours (I have 144Kbit DSL). Sorry about the large enchilada.

Uuencoding the data would only expand it by a factor of 1.4 although it would have the same problem with the diffs. I've been thinking about this recently myself. We want to maintain the ability to examine historical versions of the code, but actual diffs from one version to another are, in this context, meaningless. I'd like to suggest a new hierarchy /usr/firmware, which sits along-side /usr/src and /usr/ports in our distribution mechanism, but which does not use RCS files to store version information. Rather, the version information is encoded in the pathname, and files are stored and transferred as binary objects. It might look something like this: /usr/firmware/ gronk/ (this is the gronk driver) 3.57.OA.bin (where 3.57.OA is vendor's version) plugh/ 42.69/ model1.bin model2.bin model3.bin -GAWollman This seems well thought out and I certainly agree that we don't need DIFFs of firmware. I wonder if we can somehow "cheat time" and get that 13MB file out of the source tree and retro-actively tag the new scheme so that we don't have to carry it around forever :-) -- __--_|\ Julian Elischer / \ [EMAIL PROTECTED] ( OZ) World tour 2000 --- X_.---._/ presently in: Perth v To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

This structure can already take care of most of the problems like this one because it has multiple mechanisms whereas the source tree has only one.
