Subject[PATCH v2 0/2] Enable read timeout specification for sbefifo read
Date
Certain SBE operations (e.g. collecting trace information from processors)
can take long time (> 10 seconds) to finish before SBE can respond.
Such operations will currentlly timeout due to the default response
timeout of 10 seconds. This patchset allows users to set a longer timeout
using ioctl on the sbefifo device fd, before issuing SBE operations that
are likely to take longer.

v2 changes:
- uint32 --> u32
- Avoid resetting the read timeout after single operation. Use ioctl
to set the read timeout per open fd for sbefifo device.
- Specifying 0 value to ioctl will reset the timeout to default value
- Document ioctl behaviour in uapi/linux/fsi.h


Amitay Isaacs (2):
fsi: sbefifo: Use specified value of start of response timeout
fsi: sbefifo: implement FSI_SBEFIFO_READ_TIMEOUT ioctl
