Hi johnyoun:
I found a suspected bug, and I am writing to confirm with you.
In the function
dwc2_gadget_complete_isoc_request_ddma(drivers/usb/dwc2/gadget.c).
Only the first request from the eq queue is processed while maybe there are
more than one descriptors done by the HW.
1. Each usb reque

Hi guys:
Thanks for the helpful comments, after rethinking the issue, I have proposed
the following change:
1. follow_pte instead of follow_pfn.
2. vmf_insert_pfn loops instead of io_remap_pfn_range
3. proper undos when some call fails.
4. keep the bigger lock range to avoid unessary pte install

Hi perex and tiwai:
I have met a timeout case when capture audio from snd-usb-audio device,
when the host call the pcm_read and get into the wait_for_avail function.
The following happends
1. No available data for capture(maybe because of the late response audio data
by the uac device)
2. The
t get overflow, the change has no side affect.
Thanks.

Hi
Currently, the ion mapped to userspace will be forced with VM_IO and VM_PFNMAP
flags.
When I use the ion memory to do the direct-io, it will fail when reaching the
get_user_pages,
Back to the VM_IO and VM_PFNMAP flag, there two flags are introduced by the
remap_pfn_range called
by the ion
41 matches
