Hi List,
my kernel dies while probing parport with the following last words:
[ 3.672199] parport_pc 00:0b: reported by Plug and Play ACPI
[ 3.677969] parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA]
[ 3.687691] hwdev DMA mask = 0x0000000000ffffff, dev_addr = 0x0000000020000000
[ 3.694916] Kernel panic - not syncing: swiotlb_alloc_coherent: allocated memory is out of range for device
I haven't started a bisection yet, but this seems to be introduced
somewhere between 2.6.26 and 2.6.27, at least 2.6.26 was working without
problems. The dmesg log + config was obtained from a kernel compiled
from git on 10/16/2008.
I've attached the configuration + dmesg log to this mail. Board is an ASUS
DSBF-D12 with 2 E5410 Processors.
Cheers,
Sven.

This bug hits me, too. Looks like swiotlb assumes that the alloc caller
must set GFP_DMA appropriately by itself since GFP_DMA hack was
removed. The patch below should fix this particular case.
HOWEVER: the fundamental problem appears to be in swiotlb itself.
It assumes that iotlb pages are in DMA area. But, in this case, the
driver sets 24bit DMA (as of PnP) while iotlb pages are allocated
under 32bit DMA via alloc_bootmem_low_pages(). This doesn't work, of
course.
So, even adding GFP_DMA works mostly, it has still potentially
breakage when you can't get the page and fall back to iotlb pages,
just like the panic above.
Also, the removal of GFP_DMA hack is a bad idea. For example, if a
device requires 28bit DMA mask, it doesn't set always GFP_DMA for
allocation because pages in ZONE_NORMAL may be inside that DMA mask.
Normal allocators allow this behavior but swiotlb allocator doesn't.
(Correct me if I'm wrong here -- I haven't followed much the recent
changes.)
Last but not least, I think panic() in allocation error path is too
strict. Usually returning NULL isn't always fatal error, so give some
more chance to debug, e.g. by calling WARN() (or whatever) instead of
panic().
thanks,
Takashi

The patch below is to a workaround for that.

This happens with 2.6.27, right? GFP_DMA hack was removed post
2.6.27. What kernel version do you hit this problem?
Post 2.6.27, x86's alloc_coherent works a bit differently, but neither
require the caller set to GFP flag. arch/x86/kernel/pci-dma.c does
with 2.6.27 and asm-x86/dma-mapping.h does with post 2.6.27.

If a device has 24bit dma mask, alloc_coherent is supposed to use
GFP_DMA.

28bit DMA mask is supposed to be handled properly. Firstly, we try
with DMA_32BIT_MASK and if an allocated address is not fit for 28bit
mask, we try GFP_DMA again.

Yeah, this was discussed several times. The problem is that many
drivers assume that dma mapping operations, map_single, map_sg, and
map_coherent, always succeed and doesn't even check the errors. So we
have some panic() in IOMMU drivers to prevent really bad events like
data corruption.

2.6.27 works fine, at least on my machine.
Likely a post-2.6.27 regression.

Yes. But what happens if __get_free_pages() fails? Then you get the
same problem.

Yep, dma_generic_alloc_coherent() works like that for ages.
My point is about swiotlb_alloc_coherent(), and I don't see the
relevant code there...

Well, but also for alloc_coherent()? Returning NULL from
dma_alloc_coherent() is really no fatal error. If the caller doesn't
check the return value, then it's a more serious bug, I'd say.

Ok, it makes sense because I don't see any major changes to swiotlb

Yeah, but __get_free_pages() with GFP_DMA fails, what can we do in
such case? You think that it's a good idea to change swiotlb to
allocates < 16MB iotlb pages? I'm not sure it's worth to do
that. 24bit dma mask devices are disappearing.
About the bug that you hit, I suspect that dma_map_coherent() in
asm-x86/dma-mapping.h doesn't set gfp flags correctly.
dma_map_coherent() calls swiotlb_alloc_coherent with the flags GFP_DMA
set? parport driver set dev->coherent_dma_mask properly?

Oops, you are right. swiotlb doesn't try again with GFP_DMA now. Joerg
changed the GFP_DMA retry mechanism work only for pci-nommu.c It broke
GART IOMMU and x86's swiotlb. I modified dma_generic_alloc_coherent to
work with pci-nommu and GART. I promised Ingo to fix swiotlb too but I
forgot about it.
Sorry, I'll fix this soon but your case (28bit mask) is supposed to
work without the GFP_DMA retry mechanism. As I wrote above, I suspect
that dma flag is not set correctly.

Probably, the majority check dma_alloc_coherent failure. I'll check
this later to remove panic() in alloc_coherent in IOMMUs.

Just return NULL instead of a kernel panic.

Seconded, I don't think it's worth to allocate iotlb pages in <16MB,
too. The case with GFP_DMA is somewhat special and mostly for
obsolete devices.

The parport driver itself passes always GFP_KERNEL. So I added
GFP_DMA in my initial patch as a workaround.
The device of the parport driver is passed by another, and the driver
doesn't care about DMA mask by itself. In the panic case, it seems
from PnP, and PnP bus has set it to 24bit beforehand, I guess.

Yes, the parport case should be fixed by passing GFP_DMA.
But, the unconditional panic should be still fixed.

Hmm, have you actually tried your patch?
dma_alloc_coherent clears the gfp zone flags that the callers pass. So
even if a driver passes GFP_DMA, swiotlb_alloc_coherent doesn't get
GFP_DMA. So I'm not sure how your patch fixes the parport problem.
The current dma_alloc_coherent (asm-x86/dma-mapping.h) handles the gfp
flags in the exact same way as the old dma_alloc_coherent
(pci-dma.c). Neither sets GFP_DMA even if coherent_dma_mask is
24bits. The old code is fine because of the GFP_DMA retry
mechanism. But if coherent_dma_mask is 24bits, there is no point to go
into the GFP_DMA retry mechanism. We should use GFP_DMA in the first
place.
How about the following patch?

Err, sorry, no I checked only the combination of two patches.

Thanks, I can't find the commit right now so I'm not sure if you need
the patch description but anyway, here's a sane format of the patch.
=
From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
Subject: [PATCH] x86: use GFP_DMA for 24bit coherent_dma_mask
dma_alloc_coherent (include/asm-x86/dma-mapping.h) avoids GFP_DMA
allocation first and if the allocated address is not fit for the
device's coherent_dma_mask, then dma_alloc_coherent does GFP_DMA
allocation. This is because dma_alloc_coherent avoids precious GFP_DMA
zone if possible. This is also how the old dma_alloc_coherent
(arch/x86/kernel/pci-dma.c) works.
However, if the coherent_dma_mask of a device is 24bit, there is no
point to go into the above GFP_DMA retry mechanism. We had better use
GFP_DMA in the first place.

The patch seems working fine. Thanks!

Ingo, what is the status about these patches?
They don't appear in rc2.
thanks,

Will send it today-ish. -rc2 was strictly for brown paperbag bugs
crashing more than half of all testsystems.
