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
