* tests: Check QVIRTIO_F_ANY_LAYOUT flag in virtio-blk testMarc Marí2015-03-101-46/+52
| | | | | | | | | | | | | Check the QVIRTIO_F_ANY_LAYOUT flag before performing operations with 2 descriptor layout. This is to follow the specification strictly.

* libqos: use microseconds instead of iterations for virtio timeoutStefan Hajnoczi2014-09-291-25/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hosts are slow or overloaded so test execution takes a long time. Test cases use timeouts to protect against an infinite loop stalling the test forever (especially important in automated test setups). Commit 6cd14054b67774cc58a51fca6660cfa1d3c08059 ("libqos virtio: Increase ISR timeout") increased the clock_step() value in an attempt to lengthen the virtio interrupt wait timeout, but timeout failures are still occuring on the Travis automated testing platform. This is because clock_step() only affects the guest's virtual time. Virtio requests can be bottlenecked on host disk I/O latency - which cannot be improved by stepping the clock, so the fix was ineffective. This patch changes the qvirtio_wait_queue_isr() and qvirtio_wait_config_isr() timeout mechanism from loop iterations to microseconds. This way the test case can specify an absolute 30 second timeout. Number of loop iterations is not a reliable timeout mechanism since the speed depends on many factors including host performance. Tests should no longer timeout on overloaded Travis instances.

* libqos: improve event_index test with timeoutStefan Hajnoczi2014-09-291-4/+4
| | | | | | | | | | | | | | | | | | | The virtio event_index feature lets the device driver tell the device how many requests to process before raising the next interrupt. virtio-blk-test.c tries to verify that the device does not raise an interrupt unnecessarily. Unfortunately the test has a race condition. It spins checking for an interrupt up to 100 times and then assumes the request has finished. On a slow host the I/O request could still be in flight and the test would fail. This patch waits for the request to complete, or until a 30-second timeout is reached. If an interrupt is raised while waiting the test fails since the device was not supposed to raise interrupts.
