QEMU : QSPI test fails with connection timed out


When running a QSPI test [read/write operation], a connection time-out is observed.

Why is it failing?


In QEMU, QSPI is modeled totally unrelated to timing, which makes the guest behavior unpredictable when the guest software is working with time-out.

Work-around: The present timeout tolerance should be increased in order to resolve this issue.

Change the tolerance to 200 in spi.c line 956, located in /linux-xlnx/tree/master/drivers/spi/spi.c.
