Um, are you sure? It looks highly modified to me, the diff to the
original tarball (if I didn't do something stupid) is 700KB.

Yes, definately. Without a Signed-off-by we cannot commit.

I think that's the intention, but we need an explicit, written,
statement in the code / blob which says which rights exactly we have.
OK, here's a first review of Corey's posted patch. I'll ignore coding
style issues for now and concentrate on functional stuff, but before
we commit the code should follow our usual coding style (which is pretty
much identical with the Linux coding style). Please see

Who is that? Please don't put such comments in the code, they don't
help when trying to understand the code. Instead, add comments which
explain what the code does and why.

Is this an error case? If so, please print a warning or error message.

As it's not used, we can drop this debug stuff. Ideally, it should be in
a global debug.c somewhere as it looks useful for other chipsets too.

This file is really trivial, drop Tyan/AMD from the Copyright lines here
and just make this (C) SiS, I think that should be ok.

Please add a comment why the delay is needed and why it's exactly
540 and not 530 or 560.

Why the #if 0 and #if 1 above? Is this early debug left-overs?

This is never ever used because of the #if 1 above. Drop it?
Still useful?

Ditto.
Please try to avoid "#if 1" constructs if possible. Either the code is
needed or not.

So this is board specific? In that case is shouldn't be in the
southbridge, I guess.

Many magic constants? Does it make sense to use #defines here? What are
the numbers?

This is dead code and never reached because of the "return" above.
Is this intentional? Should the "return" be dropped or this code?

Please use #defines for most register values, instead of using the plain
numbers. For example, I have absolutely no idea what 0x54 could be,
but if the name was something like SIS966_ENABLE_AUDIO or so that would
be a lot more helpful.
Please don't forget that most of us do _not_ have access to the
datasheets, so please make the code as easily understandable as possible
and please add as many comments as possible so we are able to change the
code later (at least to some degree) without access to the datasheets.

More debug code. Maybe we should not drop it, but at least make it easy
to enable/disable it by useing a SIS966_DEBUG macro (or so) at the top
of the file.

This function looks like someting from src/device/*, is it modified? Can
we use the generic function here, instead of cloning/modifying this one?

These should be uint32_t. There are many other such places in the code.
In general, please use uint8_t and friends for values which have a
certain known/explicit length (registers etc).

This file should contain a lot more register defines etc. to make the

Hm, maybe this file can/should be merged into sis966_usb2.c (or vice
versa). Should be no problem code-wise, as the PCI IDs determine which
init code gets executed. Are there other reasons to split this?

This fine is an almost exact copy of the MCP55 file. Here's the diff
(apart from renaming MCP55 to SIS966):
-#if HT_CHAIN_END_UNITID_BASE != 0x20
+#if HT_CHAIN_END_UNITID_BASE < HT_CHAIN_UNITID_BASE
So please try to make on common such file, and let's use it in all
chipsets, not clone it again and again.

Exact clone of the MCP55 file, except for
- PCI_ID(PCI_VENDOR_ID_NVIDIA, PCI_DEVICE_ID_NVIDIA_MCP55_HT),
+ PCI_ID(PCI_VENDOR_ID_NVIDIA, PCI_DEVICE_ID_SIS_SIS966_HT),
So same as above, this should not be copy-pasted but rather made generic so
all chipsets can use it.

Almost the same as the MCP55 file. It's very short though, not sure it
makes sense to merge them in this case.

See beginning of this mail, we need an explicit written license for
this file if we are to distribute it.
At the very least it has to say we are allowed to (re)distribute it
etc., but it would be even better if we had source code under an
open-source license, of course. This is not a _must_ (although it
would be great), but having at _least_ redistribution rights is a
_must_, otherwise we cannot commit this file.

Drop this completely, please. This information should be in Config.lb or
in the wiki or something...
Thanks for reading all of this :)
And thanks for all your hard work and releasing the code, of course!
Please try to fix the above issues as far as possible, and then post
updated patches to this mailing list again. Preferrably patches (not
tarballs), and please split them up in three different parts for
easier reviews: one patch for northbridge, one for southbridge,
one for the mainboards.
Thanks a lot, Uwe.
