Hi all,
I haven't managed to get as far as a bugfix for this, but I've bisected
some issues seen on v4.10+ with a Chromebook of the Veyron family (Jaq,
in particular). v4.9 works fine.
[...]
By the way, Kevin (CC'd) says he noticed similiar Wifi issues on an
Exynos 5800 Peach chromebook, but not on an Exynos 5250 Snow chromebook.
I haven't picked these apart yet to see what the differences and
similarities are, but presumably it's not actually a Rockchip-specific
bug. Maybe related to the way power sequencing is plumbed for these, for
example?
I'm not sure but if card-detecting is polling, the timing issue could be occurred.
I don't know much about MMC in general, nor about this driver. Any
chance you'd accept reverts of the patches in question though? This is a
huge regression, and there were only a few relevant changes that seem to
have triggered this. I can try to come up with something targeted, but
I'm not going to even try if that'd get rejected up front.
Untile now, none of my(and my colleagues') rockchip platforms are able
to reproduce this issue, so I can't tell what exactly the problem is.
However, I noticed you mentioned that the Exynos platforms are also
affected by rpm of dwmmc. I don't see dw_mmc-exynos enable this feature,
so it looks quite odd to me!
Can I or Eddie get a Veyron board to help you debug it?
Brian
