* qtest: don't report signals if qtest driver enabledMichael S. Tsirkin2014-02-131-0/+5
| | | | | | | | | | | | qtest driver always uses signals to kill qemu no need to report it, whatever the accelerator state. Add API to detect qtest driver, and suppress reporting signals in this case. Reported-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Michael S.

* qtest: split configuration of qtest accelerator and chardevPaolo Bonzini2013-12-101-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | qtest uses the icount infrastructure to implement a test-driven vm_clock. This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

* qtest: Fix FMT_timeval vs time_tRichard Henderson2013-09-021-4/+4

* aio / timers: Use all timerlists in icount warp calculationsAlex Bligh2013-08-221-1/+1
| | | | | | | | | | | | | | | | | | | Notify all timerlists derived from vm_clock in icount warp calculations. When calculating timer delay based on vm_clock deadline, use all timerlists. For compatibility, maintain an apparent bug where when using icount, if no vm_clock timer was set, qemu_clock_deadline would return INT32_MAX and always set an icount clock expiry about 2 seconds ahead. NB: thread safety - when different timerlists sit on different threads, this will need some locking. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
* qtest: Don't reset on qtest chardev connectMarkus Armbruster2013-07-181-1/+6
| | | | | | | | | | | | libqtest's qtest_init() connecting to the qtest socket triggers reset. This was coded in the hope we could use the same QEMU process for multiple tests that way. Never used. Injects an extra reset even when it's not used, and that can mess up tests such as the one of -boot once I'm about to add. Drop it.

| | | | | | | | | | | Handle the addresses and values for {in,out}[bwl] as unsigned (ie with strtoul), as per the protocol specification comment. This fixes a test failure in test_i440fx_defaults on 32-bit hosts where the test tries to write 0x80000000 and qtest was instead writing 0x7fffffff.

* qtest: use synchronous I/O for char deviceAnthony Liguori2013-03-261-1/+1
| | | | | | | | | | | Peter reported that rtc-test would periodically hang. It turns out this was due to an EAGAIN occurring on qemu_chr_fe_write. Instead of heavily refactoring qtest, just use a synchronous version of the write operation for qemu_chr_fe_write to address this problem.

* qtest: add test frameworkAnthony Liguori2012-03-301-0/+354
The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.
