 Works fine for me tested on :
 
 03:0e.0 SCSI storage controller [0100]: Adaptec AIC-7892P U160/m [9005:008f] 
 (rev 02)

I hope this is enough for these patches to be accepted.

If it is not, please let me know what do I need to do more.

 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 :(

[PATCH 0/3] debloat aic7xxx and aic79xx drivers

2007-10-14 Thread Denys Vlasenko
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.

  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).

Attached are three patches which fix that:

   textdata bss dec hex filename
 261433   500181172  312623   4c52f 
linux-2.6.23-rc1.org.t/drivers/scsi/aic7xxx/built-in.o
 199654   500181172  250844   3d3dc 
linux-2.6.23-rc1.aic.t/drivers/scsi/aic7xxx/built-in.o
 184014   213141172  206500   326a4 
linux-2.6.23-rc1.aic1.t/drivers/scsi/aic7xxx/built-in.o
 20237828501172  206400   32640 
linux-2.6.23-rc1.aic2.t/drivers/scsi/aic7xxx/built-in.o

1-debloat.patchdeinlines a lot of functions
2-addstatic.patch  adds statics, #ifdefs out huge amount of unused code, adds 
consts
3-addconst.patch   adds more consts

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 actually touch any logic, code changes
are pretty minimal.

Compile tested and applies cleanly to 2.6.23-rc1, applies with some fuzz to 
2.6.23-rc3.

Please propagate to mainline.

 Yowza.  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.
