* tests/acceptance: add reverse debugging testPavel Dovgalyuk2020-10-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This is a test for GDB reverse debugging commands: reverse step and reverse continue. Every test in this suite consists of two phases: record and replay. Recording saves the execution of some instructions and makes an initial VM snapshot to allow reverse execution. Replay saves the order of the first instructions and then checks that they are executed backwards in the correct order. After that the execution is replayed to the end, and reverse continue command is checked by setting several breakpoints, and asserting that the execution is stopped at the last of them.

* cpu-timers, icount: new modulesClaudio Fontana2020-10-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | refactoring of cpus.c continues with cpu timer state extraction. cpu-timers: responsible for the softmmu cpu timers state, including cpu clocks and ticks. icount: counts the TCG instructions executed. As such it is specific to the TCG accelerator. Therefore, it is built only under CONFIG_TCG. One complication is due to qtest, which uses an icount field to warp time as part of qtest (qtest_clock_warp). In order to solve this problem, provide a separate counter for qtest. This requires fixing assumptions scattered in the code that qtest_enabled() implies icount_enabled(), checking each specific case.

| | | | | | | | | | | | | | | | | | | | | | | Convert qemu-ga-ref to rST format. This includes dropping the plain-text, pdf and info format outputs for this document; as with all our other Sphinx-based documentation, we provide HTML and manpage only. The qemu-ga-ref.rst is somewhat more stripped down than the .texi was, because we do not (currently) attempt to generate indexes for the commands, events and data types being documented. As the GA ref is now part of the Sphinx 'interop' manual, we can delete the direct link from index.html.in.

| | | | | | | | | | | | | | | | | | | | Some of our documentation is auto-generated from documentation comments in the JSON schema. For Sphinx, rather than creating a file to include, the most natural way to handle this is to have a small custom Sphinx extension which processes the JSON file and inserts documentation into the rST file being processed.

I also know Jiaxun Yang from the #debian-mips IRC channel. I know that they are both very competent and have a good knowledge of the open source world. I therefore agree that they are good additions to maintain and/or review the MIPS part of QEMU.
