New brcmfmac errors in 4.12: brcmf_sdio_rxglom: sublen ... not multiple of 8

[Hans de Goede]

Hi,

I've just rebased my personal kernel tree to what will soon be 4.12-rc1
and I'm getting my dmesg log filled with the following errors:

[   32.528271] brcmfmac: brcmf_sdio_rxglom: sublen 524 not multiple of 8
[   32.528296] brcmfmac: brcmf_sdio_rxglom: sublen 84 not multiple of 8
[   33.063241] brcmfmac: brcmf_sdio_rxglom: sublen 1492 not multiple of 8

Other brcmfmac dmesg messages:

[   16.020013] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Jul 17 2013 07:36:07 version 6.10.197.71 (r412987) FWID 01-882d2634

This is on a Asus T100TA which uses a 43241b1

Regards,

Hans

Ok, this seems to be a regression caused by:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6e84ab604bded
"brcmfmac: properly align buffers on certain platforms with 64 bit DMA"

I believe this may need a different fix then that.

Hans

After a brief look at the code I'm not sure that the check actually checks
for an error condition. Apart from the error messages:
Do you face issues with the functionality of the driver?

Yes after a while I get -ETIMEOUT errors for any sdio transfers
to the device. But I'm not sure if this is caused by this commit,
I think I've seen this once with 4.11 too.

I've reverted the commit for now, but I'm fine with instead of
doing the revert dropping the error check if the brcmfmac developers
think that is ok. Currently the ETIMEOUT seems to be gone, so
if dropping the revert causes it to re-appear then we know more.

Regards,

Hans

Instead of reverting please give this patch a try and let me know if it
works for you.

Unfortunately I don't have hardware to test this (as sdio isn't available
on Odroid C2). However the patch looks logical and good to me.

I add Helmut as he gave his Tested-by for commit 5ef1ecf060f28e
"mmc: sdio: fix alignment issue in struct sdio_func".
Maybe he can test your patch as well.
