Subject: [PATCHv4 0/2] cppi41 dma fixes for v4.10-rc cycle
Date: Thu, 19 Jan 2017 08:49:06 -0800 [thread overview]
Message-ID: <20170119164908.9472-1-tony@atomide.com> (raw)
Hi all,
I'm using v4 naming here as the earlier patch "dmaengine: cppi41: Add dma
support to da8xx" has been separated from the error -115 issue. We've
identified so far three musb and cppi41 regressions:
1. Error -71 regression with musb
This is not dma related, and fixed with recently posted patch
"[PATCH 1/2] usb: musb: Fix host mode error -71 regression".
2. Error -115 regression with cppi41 dma with musb
This regression was caused by commit 098de42ad670 ("dmaengine:
cppi41: Fix unpaired pm runtime when only a USB hub is connected")
and causes runtime PM autosuspend delay to time out on active dma
transfers when connecting a mass storage device to a usb hub.
This is fixed in the first patch in this series.
3. Race with runtime PM and cppi41_dma_issue_pending()
This is really a separate issue from the error -115 problem, and
fixed with the second patch in this series. That's minimal v4
version of the "dmaengine: cppi41: Fix oops in cppi41_runtime_resume"
patch.
Regards,
Tony
