Linux 2.5.12-dj1

Linux 2.5.12-dj1

[Dave Jones]

Back up to date against Linus. Lots of resyncing going on, still
quite a lot left to go too.

It's lost ~2MB in overall size over the last month, which isn't
bad considering quite a bit has also been going in at the same time.
The framebuffer work I'm leaving to James. Eventually it will all
disappear from my tree magically. Hopefully.

As usual,..

"dev_list" is now defined in two files and I got the following compile
error when building a kernel with all Bluetooth drivers compiled
statically into the kernel:

This is the output while compiling aic7xxx_old.c:

aic7xxx_old.c:11950: unknown field `abort' specified in initializer
aic7xxx_old.c:11950: warning: initialization from incompatible pointer type
aic7xxx_old.c:11950: unknown field `reset' specified in initializer
aic7xxx_old.c:11950: warning: initialization from incompatible pointer type
aic7xxx_old.c:11950: duplicate initializer
aic7xxx_old.c:11950: (near initialization for `driver_template.slave_attach')

aic7xxx_old.c:11950: (near initialization for `driver_template.bios_param')
make[3]: *** [aic7xxx_old.o] Error 1

aic7xxxx_old.c compiles in 2.5.12 and 2.5.7-dj3, although it may
be broken in some other way.

Is it appropriate to edit .config to use the new driver by setting:
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_CMDS_PER_DEVICE=253
CONFIG_AIC7XXX_RESET_DELAY_MS=15000

Is the new driver experimental, or ?

The chunk of code introduced to the ramdisk code in 2.5.12-dj1 is
a forward port of what happened in 2.4.  It probably needs fixing up
again (I've rewritten and jiggled it a little since the initial
forward port).  I'm not entirely sure it works as advertised anymore.

It's on my radar, I'll take a look for the next patch I put out.

    Dave.

Stereotypical "needs error handling code" errors.

Yep. Removal of the abort/reset methods shows us which SCSI drivers
don't have any error handling. So they 'worked' up until you got
an error, and then...

I've no experience of either driver in practice, so I'm not actually
sure what the game plan is here. Someone want to fill us in? Justin?

You probably don't want to compile all _cs.o modules into the kernel.
But it's a bug in any case. dev_list should be static.  I'll fix that.

Since I have not reviewed how the driver has been modified for 2.5,
I can't really say much about its status in that branch.  The driver
is not "experimental" in the 2.4 branch.
