I think this question is better for the ARM guys. CC'd

With commit 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32"), we
limited ZONE_DMA to 1G to accommodate the RPi4 requirements. ZONE_DMA32
spans to the end of the 32-bit space. So with a CMA region that goes
across the 1st GB, you'd hit this problem.

The dma_contiguous_reserve() call in arm64 uses ZONE_DMA32 as the upper
limit under the assumption that you don't need CMA in ZONE_DMA. But this
one doesn't have a lower limit.

What platform is this and how to you request the CMA size (cmdline)? Do
you use a fixed base? Also, do you want the CMA in ZONE_DMA or
ZONE_DMA32?

So I guess it's this test that fails as the CMA now spans ZONE_DMA and
ZONE_DMA32.

This is stingray (arch/arm64/boot/dts/broadcom/stingray/bcm958742k.dts).
cma is specified on cmdline as "cma=1G". The full boot log was in the
attachment.

Do

I'm not sure which zone we want it in. I'm assuming ZONE_DMA32. Before
that change there was only one zone. If I disable ZONE_DMA I don't see
the error, though I haven't tested anything. I don't really understand why
ZONE_DMA is enabled by default if it's a requirement for Rpi only. I'm
assuming it should work as is with both zones enabled but not clear how
cma spans the two zones. Was there a reason for having both zones
enabled as the default?

Yes it fails here.

Would you mind attaching it again, I was added to the conversation later.

It's enabled by default to be able to boot all boards with a common kernel
image.

IIRC the allocation algo for CMA placement tries to fit it as high as possible
in ZONE_DMA32, but I can't really say much more without the logs.

Nicolas

Sure, it is attached. Thanks for taking a look. This is a boot with
"arch/arm64/configs/defconfig" and the previously mentioned dtb.

Well there's your problem - both zones are only nominally 1GB to begin 
with, and both have stuff in them before we even get to placing CMA. To 
be honest, even without ZONE_DMA that looks pretty tight.

OK I see. I don't get the zone range debugs with my working vs generic
defconfig. I'm not sure why. We have quite a bit reserved memory. I
understand better what's happening now, thank you.
