The changes to dma-mapping.h and sound/core/memalloc.c need to be  
explained and odds are will not go in as is.

Also, the .dts should be v1 format.

Urgh.  Could you split this into a number of smaller patches, each with
a proper commit message that doesn't break the build on its own?

See some initial comments below.

I don't see a reason to split out the bootwrapper support into two
separate files.  You should be able to have a single file for it.

You don't do anything platform specific at all in this file.  You
should be able to just reuse the bamboo.c file.  Look at Yosemite for
how that is done.

Ok, now I'm confused as to why you aren't doing this in your platform
file (which would make it specific, and therefore justify its existence.

You definitely need to explain what you're doing here with a commit log.

This needs to be sent to the sound maintainer.  And I'm sure they
probably won't like the ifdefs.

This is a (bad) hack that I also use on the AmigaOne to get the ALSA sound
drivers working with DMA, because ALSA doesn't work with dma-noncoherent.c.
The problem is the "nopage" mechanism, which fails with non coherent DMA
allocations due to their own virtual address space (correct me, if I'm
wrong).

See this thread for more info:
http://readlist.com/lists/vger.kernel.org/linux-kernel/45/226541.html

This is a general problem that affects all powerpc boards that use
dma-noncoherent.c with ALSA PCI drivers.

Re: [PATCH] Sam440ep support

[Benjamin Herrenschmidt]

I wonder about the way this is split between the platform file and this
"sysdev" file.

The platform file is so small (and similar to other platform files) that
I wonder if we can move toward something aking to the 5200 simple
platform, that is have one platform with a list of matches.

Now, the sysdev file I'm not so happy about. sysdev isn't supposed to
contain board code, it's supposed to contain drivers for low level
system devices such as interrupt controllers, PCI bridges, etc... that
are shared by multiple platforms.

The code in there definitely looks like it should be done differently
too.

The IBM IIC driver should already have an of_platform_device created for
it, so we can have here a generic driver for that chip that instanciates
itself based on it. No need to create a platform device .. Or is the ibm
iic host driver only in the form of a platform device nowadays ?

That can be a problem as we end up with basically 2 devices for the same
device node... Why wouldn't ibm iic be an of platform driver ? If it's
for arch/ppc compatibility, we don't care..

You can then expose all i2c devices underneath it with generic code too
too no ? I haven't followed the discussion about i2c bindings but it
looks like you should be able to have some generic code that instanciate
all i2c devices in the device tree based on nodes under a given
controller...

Ben.

They can certainly not be merged in their current form. Guiseppe, what
is the underlying problem, can you describe it in details ?

I addition, that gets called on all platforms, not only sam440ep, which

The link above doesn't provide any useful information on the problem and
it contains itself a non working link...

Can somebody explains exactly what's going on ? That shouldn't be hard
to fix. I can't believe the problem has been around for 2 years and
nobody actually bothered fixing it properly.

Send me a sound card that needs that hack and I can take care of it
myself.

Correct.  I was starting with code organization vs. specific comments
since it was all one big patch.  I'll get into details when it gets
split properly :).

As of 2.6.26-rc1 (and I believe Josh's for-2.6.26 tree?) the ibm iic
driver is available as an of_platform driver. So you need a very recent
kernel.

However, the patches should be available in the linuxppc-dev archives if
you search for them.

Look at platforms/44x/warp.c for an example of how to initialize the
driver for the 440EP.

Sorry, I didn't check the embedded link. This one should work:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0406.2/0801.html

IIRC the problem is the mmaping of non coherent DMA allocations, as you
already know. The link above points to a very old (from 2004) and quite
long thread where the correct DMA API for mmaping DMA allocations was
discussed.

Takashi Iwai posted a preliminary patch a long time ago. I tested it on my
machine and it failed with non coherent scatter-gather DMA allocations
(I guess almost all ALSA PCI drivers use SG DMA?).

Thanks!

How does Alsa allocate such SG ?

I can't answer this question. *ducked* :-) Takashi?

FYI: I posted the results of the test with Takashi's dma_mmap_coherent
patch here:
http://ozlabs.org/pipermail/linuxppc-dev/2006-June/024078.html

On the other side it looks like this problem does not only affect ALSA.
As far as I can tell also some V4L(2) drivers have a problem with mmaping
non coherent DMA allocations, but I'm not sure (it's a long time since I
did some tests with video cards on my AmigaOne).

Naturally I can do some tests, if you or Takashi come up with a new
patch.

Thanks!

Time that we sort that stuff out once for all..

sg allocations are usually lists of page, so virt_to_page shouldn't be a
problem in the first place, though we still need some way to get the
right prot attributes.

The problem is that ALSA SG buffer is composed from pages allocated
via dma_alloc_coherent(), and the pages are retrieved via virt_to_page
for DMA pages, as found in sound/core/sgbuf.c.

I didn't care about SG-buffer cases in my initial patch, and it's a
bit messy.  The current code requires page lists becasue it calls
vmap() to get a virtually linear buffer.

Hrm... the problem is that you aren't supposed to make up sglists with
the result of dma_alloc_coherent... It might be a limitation of our core
DMA API, but that's we have to deal with today..

If you're going to make up sglists and call vmap, you should allocate
pages with normal GFP. If that is a problem vs. DMA'bility of those
pages, then ... we have a problem :-)

I don't think we can easily update the DMA API at this stage. What we
could do is provide a way to retrieve the struct page array from the
result of dma_alloc_coherent...

Ben.

Another option is to allocate the pages with gfp, and then dma_map_sg
the result... However, if we do that, we do need to add a way to vmap
with the right protection in order to get a coherent (ie. non cacheable)
mapping. I'm not even sure all archs can do that....

Ben.

In most cases, it can be obtained via pfn_to_page(), I suppose.  But,
it's definitely arch-specific thingy, and a generic solution would be
really appreciated.

Alternatively, we can change the ALSA PCM core code that accesses the
virtual linear buffer and handles SG-buffers as they are.  Maybe it'll
give a bit more useful clean-up in the whole memory-management codes
in ALSA in the end.

You can't get a pfn out of the result of dma_alloc_coherent on
non-coherent powerpc at least. It's a virtual mapping created from the
underlying pages set to be non-cacheable. virt_to_* will do no good.

I need to get my head around what the exact usage in Alsa is, and it's a
bit too late for me to thing right now :-)

Re: [PATCH] Sam440ep support

[Giuseppe Coviello]

I've prepared another path to add the support for the sam440ep;
shortly I've merged arch/powerpc/boot/sam440ep.c in
arch/powerpc/boot/cuboot-sam440ep.c; I've inserted the code to make
the rtc works directly in arch/powerpc/platforms/44x/sam440ep.c (so
there isn't any arch/powerpc/sysdev/sam440ep.c anymore), and I've
cutted away the nasty hack (dma-mapping.h and memmalloc.c) to make the
sound works.

Sorry for our impatience, but we'll happy to know if this (second)
version of the patch
is acceptable, and, of course, what could be the future of this same patch.

Thank you, Giuseppe

It still isn't split up quite as much as I'd like, but I'll review it
over the weekend.  If there is nothing drastically wrong with it, I'll
probably take it for 2.6.27.

If you can provide a useful changelog message, that would be nice.
Otherwise I'll have to make one up myself.  (Like, what is the sam440ep
board?  Who makes it?  What is it's purpose?)

OK, here is another patch for testing.  Since I lost my old patch
somewhere (and it's not worth to dig the archive), I wrote it up
quickly from scratch.  This version should cover both SG and non-SG
buffers.  It's against the latest git tree.

The patch adds a hackish verison of dma_mmap_coherent() for some
architectures in sound/core/pcm_native.c.  I'm not sure whether this
works.  I just tested it on X86.  It'd be appreciated if someone can
test this.

Also, this disables HDSPM driver for non-X86/IA64 since the driver has
own copy and silence methods that are incompatible with the new
SG-buffer data.


And, yes, I know we need to clean up huge messes in ALSA memory
handling routines.  But, let's fix obvious bugs before starting a big
rewrite...


thanks,

Takashi

OK, here is another patch for testing.  Since I lost my old patch
somewhere (and it's not worth to dig the archive), I wrote it up
quickly from scratch.  This version should cover both SG and non-SG
buffers.  It's against the latest git tree.

The patch adds a hackish verison of dma_mmap_coherent() for some
architectures in sound/core/pcm_native.c.  I'm not sure whether this
works.  I just tested it on X86.  It'd be appreciated if someone can
test this.

Also, this disables HDSPM driver for non-X86/IA64 since the driver has
own copy and silence methods that are incompatible with the new
SG-buffer data.


And, yes, I know we need to clean up huge messes in ALSA memory
handling routines.  But, let's fix obvious bugs before starting a big
rewrite...


thanks,

Takashi

Thanks a lot! I'll test it tonight, if I can get the lastest kernel
version running on my A1 (2.6.26-rc1 oopsed already on startup and
Kumar's fixmap patch for highmem seems to break dma-noncoherent.c).

Gerhard

Okay, it seems to work fine so far. No lock-ups or kernel oopses. Tested
with kernel v2.6.26-rc2 and a Soundblaster 5.1/EMU10k1 device (which was
not working with the old patch) on my non cache coherent G4 system.

Thanks again!

Patch looks fine, but you're missing a Signed-off-by line.  Please read
section 12 of Documentation/SubmittingPatches and add that.

Hmm, weird.  cs4281 has no SG buffer at all, so basically it cannot
work like that...

Are you sure the trigger/level settings on those interrupts is
correct?

You have no interrupt mapping for the PCI node.  How do you have
working PCI here?

Also, if these questions result in changes to the DTS, could you please
convert it to a dts-v1 format?  Otherwise I'll have to do it myself and
it's cleaner if it comes in that way.
