ide-2.4.20-pre4-ac2.patch

[Andre Hedrick]

This is out and has been forwarded to AC for review.

Others helped with ideas and concepts.

This should work on all archs in IDE, there may be other issues which
causes compile failures but should not be related to IDE.

This shall have something in it soon, as I am reviewing the pieces to pick
up and play catch up in 2.5 learning curve as to beat the Halloween

Just wanted to tell, that with this version my kernel oops while
mounting ide-scsi driven CD/DVD drives is gone. Thanks!

> This is out and has been forwarded to AC for review.

Okay, I tested this the hard way -- the root of one of my machines
got trashed. The controller used was a PDC20268 (Ultra100TX2), the
disks (with two partitions of equal size on each forming a raid0)
are IBM and WD. Soon after the kernel came up, it started spitting
messages like 'DMA disabled' and 'No DRQ after WRITE has been issued',
after which the machine froze entirely. Rebooting w/ an alternate
kernel revealed massive fs corruption with the superblock completely
overwritten.

  *** Everybody please treat this patch with extreme care. ***

Reiserfs people, this unfortunate event also made me find out about
the inability of reiserfsck 3.6.3-pre1 to rebuild the node tree --
the program pretends to work just fine but the in-kernel fs code
barfs when it's to operate on a repaired fs. 3.x.1b was able to
get the job done for me, though.

WHOA Tomas,

That is a major problem, are you using legacy patch or taskfile io?
Ben H reported he was having problems with legacy path on PPC, but the new
taskfile io worked fine.

Big jump in clean up and debloating.
If you try the patch and it repeats, you can re-LART me.

Okay, I screwed up. Obviously I haven't had much sleep lately.
In the end it _was_ the new code that made me feel soooo happy
today. So another sorry goes to Alan for blaming 2.4.20-pre4-ac2.
What a fine example of hasty reporting I've managed to display. :)

Let's revise, though:

$ tar xzf linux-2.4.19.tgz
$ mv linux-2.4.19 linux-2.4.20-pre4-ac2-newide
$ cd linux-2.4.20-pre4-ac2-newide
$ zcat ../patch-2.4.20-pre4.gz ../patch-2.4.20-pre4-ac2.gz \
	../2.4.20-pre4-ac2-newide.gz| patch -sp1
$ vi Makefile
	(modify EXTRAVERSION)
$ cp /tmp/.config .
$ make oldconfig dep clean bzImage modules

...

I appreciate all the testing immensely. Now I know to merge just the
obvious bits of that patch piece by piece as I was thinking I ought to.

Rejected. I found several errors, a couple of strange reverts and some
files being moved to clearly wrong places. It also mixes up multiple
changes.

Andre to make this work I need
	- One change per patch (within reason)
	- An explanation of what it does

For example I've got files you moved and changed, looking at that in
diff is a right pita. I've got a big diff with errors in it (eg gayle in
ppc) I can't easily be sure I can cleanly drop parts of.

Lets start with the file moving. Send me a diff for the Config/Makefile
and a lit of the files to move and where. Gayle I think should be m68k
not ppc (actually Im pretty sure), CMD640 is PCI so why file it in
legacy. "legacy" I took to mean pre PCI rather than "I think its junk"

It's for m68k and ppc Amigas, but I don't think two separate drivers are
needed.

So its actually a false divide and dumping them in "legacy" is probably
a lot simpler ?

Are there native PPC Amigas which have the Gayle? IIRC only the 1200s
and the 4000s had the Gayle...

Deal, undoing the moves.

Parsing out all the summitted stuff first for send.
Then the breakdown of the rest.

Gemme a bit to catch on to your request, Viro is trying to teach the ways
of mad patcher and not the patch bomber.

Yes, but you can put in another processor board.

Andre, you should probably remove my "patch0" from your patch
(the very first one I sent you to fix PPC compile on -ac so
you could test on your PPC). Alan already have it, I sent it
more for your own tests on PPC than for inclusion in your
patch, which is why I sent it separately from the other IDE
related patches.

Ben.

If it's PPC side is limited to PPC amiga's (APUS), then leave it
in m68k. PPC Amiga's are really m68k machines with a hacked PPC
in the CPU slot ;)

Though such problems may come back if we ever decide to support
the PPC CPU cards for old m68k macs, and if I finally merge the
support for NuBus pmacs, oh well...

Ben.
