replay: record and replay random number sources

2020-01-07T11:08:39+00:00

Record/replay feature of icount allows deterministic running of execution scenarios. Some CPUs and peripheral devices read random numbers from external sources making deterministic execution impossible. This patch adds recording and replaying of random read operations into guest-random module, which is used by the virtual hardware.

replay: add record/replay for audio passthrough

2017-03-01T14:11:44+00:00

This patch adds recording and replaying audio data. Is saves synchronization information for audio out and inputs from the microphone. v2: removed unneeded whitespace change Signed-off-by: Pavel Dovgalyuk Message-id: 20170202055054.4848.94901.stgit@PASHA-ISP.lan02.inno [ kraxel: add qemu/error-report.h include to fix osx build failure ] Signed-off-by: Gerd Hoffmann

record/replay: add network support

2017-01-06T02:38:00+00:00

This patch adds support of recording and replaying network packets in irount rr mode. Record and replay for network interactions is performed with the network filter. Each backend must have its own instance of the replay filter as follows: -netdev user,id=net1 -device rtl8139,netdev=net1 -object filter-replay,id=replay,netdev=net1 Replay network filter is used to record and replay network packets. While recording the virtual machine this filter puts all packets coming from the outer world into the log. In replay mode packets from the log are injected into the network device. All interactions with network backend in replay mode are disabled. v5 changes: - using iov_to_buf function instead of loop Signed-off-by: Pavel Dovgalyuk Signed-off-by: Jason Wang

replay: vmstate for replay module

2016-09-27T09:57:30+00:00

This patch introduces vmstate for replay data structures. It allows saving and loading vmstate while replaying. Signed-off-by: Pavel Dovgalyuk Message-Id: <20160926080810.6992.68420.stgit@PASHA-ISP> Signed-off-by: Paolo Bonzini

replay: character devices

2016-03-15T17:23:40+00:00

This patch implements record and replay of character devices. It records chardevs communication in replay mode. Recorded information include data read from backend and counter of bytes written from frontend to backend to preserve frontend internal state. If character device was configured through the command line in record mode, then in replay mode it should be also added to command line. Backend of the character device could be changed in replay mode. Replaying of devices that perform ioctl and get_msgfd operations is not supported. gdbstub which also acts as a backend is not recorded to allow controlling the replaying through gdb. Monitor backends are also not recorded. Signed-off-by: Pavel Dovgalyuk Message-Id: <20160314074436.4980.83856.stgit@PASHA-ISP> [Add stubs. - Paolo] Signed-off-by: Paolo Bonzini

replay: recording and replaying clock ticks

2015-11-06T09:16:02+00:00

Clock ticks are considered as the sources of non-deterministic data for virtual machine. This patch implements saving the clock values when they are acquired (virtual, host clock). When replaying the execution corresponding values are read from log and transfered to the module, which wants to read the values. Such a design required the clock polling to be synchronized. Sometimes it is not true - e.g. when timeouts for timer lists are checked. In this case we use a cached value of the clock, passing it to the client code.

replay: asynchronous events infrastructure

2015-11-06T09:16:02+00:00

This patch adds module for saving and replaying asynchronous events. These events include network packets, keyboard and mouse input, USB packets, thread pool and bottom halves callbacks. All events are stored in the queue to be processed at synchronization points such as beginning of TB execution, or checkpoint in the iothread.
