Hi, this is your Linux kernel regression tracker.

Linux-Input developers, do you have any idea what might be causing the
problem outline below? It's a post 5.17 regression in mainline that was
reported to bugzilla.kernel.org about a week ago, but didn't even get a
single reply. Might be some other subsystem that is causing it, not sure.

For more details check this thread or the bugzilla ticket, it has a
second comment already from the reporter.

Anyway, to get this tracked:

#regzbot introduced: v5.17..v5.18-rc4

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

the same issue exists with 5.18-rc6.

If you could test 5.18-rc1, and maybe bisect, that’d be great.

5.18-rc1 has the same issue...

Is it worth bisecting between 5.17 ad 5.18-rc1?

Maybe there are obvious suspect commits to start with?

Yes, please bisect.

After bisection:
git bisect good
f5ff79fddf0efecca538046b5cc20fb3ded2ec4f is the first bad commit

    dma-mapping: remove CONFIG_DMA_REMAP

    CONFIG_DMA_REMAP is used to build a few helpers around the core
    vmalloc code, and to use them in case there is a highmem page in
    dma-direct, and to make dma coherent allocations be able to use
    non-contiguous pages allocations for DMA allocations in the dma-iommu
    layer.

    Right now it needs to be explicitly selected by architectures, and
    is only done so by architectures that require remapping to deal
    with devices that are not DMA coherent.  Make it unconditional for
    builds with CONFIG_MMU as it is very little extra code, but makes
    it much more likely that large DMA allocations succeed on x86.

    This fixes hot plugging a NVMe thunderbolt SSD for me, which tries
    to allocate a 1MB buffer that is otherwise hard to obtain due to
    memory fragmentation on a heavily used laptop.

FYI, the reporter bisected this regression down to f5ff79fddf0e
("dma-mapping: remove CONFIG_DMA_REMAP"). CCing Christoph, who authored
that change (I wonder if it just exposed an existing bug, but well,
that's up for you to discuss).

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

Well, this just uncovered an existing bug in the driver.  You can not
just dma map memory returned from dma_alloc_coherent, and this driver
would already get vmalloc memory on arm/arm64 platforms anyway, we
now just do the same on x86 as well.

From a quick look through the trace it seems somehow
usb_hcd_map_urb_for_dma tries to create another DMA mapping for a buffer
allocated from usb_alloc_coherent that uses a dma coherent allocation
below.  It really needs to use the dma address returned from
usb_alloc_coherent instead of trying to map the URB again.  But I don't
have the slightest idea of why that only happens for this particular
setup, and I really need some helpe from the usb folks to untangle it

Could it be that bcm5974 driver just forgot to set the URB_NO_TRANSFER_DMA_MAP flag in urb transfer_flags?

If the usb driver does the allocation and dma mapping, and sets urb->transfer_dma
then it should set that flag. Otherwise usbcore will map the DMA address.

Documentation/driver-api/usb/dma.rst:

- URBs have an additional "transfer_dma" field, as well as a transfer_flags
  bit saying if it's valid.  (Control requests also have "setup_dma", but
  drivers must not use it.)

- "usbcore" will map this DMA address, if a DMA-aware driver didn't do
  it first and set ``URB_NO_TRANSFER_DMA_MAP``.  HCDs
  don't manage dma mappings for URBs.

bcm5974_add_urb_flag

quick testpatch that just adds the missing URB flags,
Does it work? I don't have this hardware myself

I will test this patch against 5.18-rc6 today on my hardware.

I can confirm that the patch resolves the problem!  Thanks so much!

Could we get that patch added to the driver for 5.18?

This is resolved in 5.18-rc7.

Thanks, everyone!

> This is resolved in 5.18-rc7.

Are you sure? The change from Mathias (thx for providing it) did not land yet.

I just tested the Ubuntu mainline build... Maybe I accidentally used the older fixed kernel I built. The fix should definitely land to fix this properly.

I'm not sure what changed, but it is working on the ubuntu mainline build of 5.18-rc7.

The aforementioned patch is not in there.

There is a dma-buf patch in 5.18-rc7, but I can't tell if that would make a difference here.

The bcm5974 driver is definitely loaded without errors:

Maybe I just missed a change to fix this; or some change fixed this accidentally (which was odd, but well, we are dealing with computers here...).

Guess the matter can be considered resolved then.

This is resolved with both 5.18-rc7 and the release version of 5.18.0 .

Building 5.18.1, this issue is rearing its ugly head again.

Mathias Nyman could we get that patch added to the driver please?

Patch sent to linux-input mailinglist

https://lore.kernel.org/linux-input/20220606113636.588955-1-mathias.nyman@linux.intel.com/T/#u

I believe this is not fixed yet. I have the same issue with 5.18.x on Gentoo, the difference is that the Realtek card reader is involved:

Not my area of expertise, but I guess the driver for the realtek card reader likely has the same underlying issue like the input driver this bug was about. Unless Mathias speaks up here to provide further info (or maybe even comes around with a fix) I suggest you report it separately (please drop a link to the report afterwards here).
