If it is not, please let me know what do I need to do more. -- vda - To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

I can test these patches on an aic7892 controller later on today if you want. I'd appreciate that. Do you, by any chance, use aic94xx driver too (drivers/scsi/aic94xx/*)? After i'm done with aic7xxx, I may attack this one. Sorry I don't have any box uses this one , but I'll ask some friends maybe someone has :) BTW while you seems to care about this driver could you have a look at : http://bugzilla.kernel.org/show_bug.cgi?id=3062 ?!? I am a desktop Linux user, so far I don't use suspend at all. Sorry. Ok , no problem maybe one 'day' the SCSI folks cares ( where the 'day' may be never ), I dunno :( -- vda Gabriel - To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH 0/3] debloat aic7xxx and aic79xx drivers
Hi, Following patches debloat drivers/scsi/aic7xxx/*. I also had to add prototypes for ahc_lookup_scb and ahd_lookup_scb to .h files. 1-debloat.patch Deinlines and moves big functions from .h to .c files. Adds prototypes for ahc_lookup_scb and ahd_lookup_scb to .h files. 2-addstatic.patch Adds statics, #ifdefs out huge amount of unused code, adds consts 3-addconst.patch Adds more consts Driver code/data size reductions: Build with debugging on (CONFIG_AIC7XXX_DEBUG_ENABLE=y): textdata bss dec hex filename 310865 499221204 361991 58607 linux-2.6.23.t/drivers/scsi/aic7xxx/built-in.o 22198727541204 225945 37299 linux-2.6.23-aic-3-addconst.t/drivers/scsi/aic7xxx/built-in.o With debugging off: textdata bss dec hex filename 298896 427541172 342822 53b26 linux-2.6.23.tt/drivers/scsi/aic7xxx/built-in.o 21606827541172 219994 35b5a linux-2.6.23-aic-3-addconst.tt/drivers/scsi/aic7xxx/built-in.o make namespacecheck goes from 400+ functions to: drivers/scsi/aic7xxx/aic79xx_core.o ahd_inq ahd_inw ahd_outq ahd_outw drivers/scsi/aic7xxx/aic79xx_osm.o ahd_insb drivers/scsi/aic7xxx/aic7xxx_core.o ahc_inq ahc_outq drivers/scsi/aic7xxx/aic7xxx_osm.o ahc_insb None of these patches touch any logic, code changes are pretty minimal. Compile tested and applies cleanly to 2.6.23. I don't have this hardware anymore and cannot run test these patches. Please apply.

Or they don't, and everything is fine. (The default y approach so to speak ;-) The problem is that we don't really have a maintainer for the aic7xyz drivers any more. Volunteers welcome. NOT IT! Take it before someone else does! Well, the semi-official maintainers are James B. and me. So I might as well do it officially. Cool. Thanks to Arjan's insistence, I also took a look at adding statics and unexpectedly discovered yet another 50 kbytes of dead code (I'm not kidding).

Looking at aic1-aic2, it looks like 20K became 'const', and only 3K *wasn't* 'const'? Exactly. There are firmware images/patches and a lot of structures with char* members pointing to text/messages. Btw, aic94xx driver needs the same treatment. -- vda - To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
