Richard Henderson 78441c04ca tests/qht-bench: Adjust threshold computation
In 06c4cc3660, we split the multiplication in two parts to avoid
a clang warning.  But because double still rounds to 53 bits, this
does not provide additional precision beyond multiplication by
nextafter(0x1p64, 0), the largest representable value smaller
than 2**64.

However, since we have eliminated 1.0, mutiplying by 2**64 produces
a better distribution of input values to the output values.

Since the seed must be non-zero, subtracting 1 means puts the

Alex Bennée c8e6793903 containers.yml: build with docker.py tooling
Instead of building the docker files directly use the same docker.py
scripting as we do for building locally. This should help ensure we
use the exact same steps and allow us to cache properly when building
locally.

To get this working you have to have a fairly recent docker binary
otherwise you will see the error message:

 => ERROR importing cache manifest from registry.gitlab....

So far docker 19.03.12 works (from the docker apt repos) but 18.09.1,
build 4c52b90 which is packaged in Debian Buster fails.

Daniel P. Berrangé 3e7b80f84d tests: improve performance of device-introspect-test
Total execution time with "-m slow" and x86_64 QEMU, drops from 3
minutes 15 seconds, down to 54 seconds.

Individual tests drop from 17-20 seconds, down to 3-4 seconds.

The cost of this change is that any QOM bugs resulting in the test
failure will not be directly associated with the device that caused
the failure. The test case is not frequently identifying such bugs
though, and the cause is likely easily visible in the patch series
that causes the failure. So overall the shorter running time is
considered the more important factor.

We have a number of container images in tests/docker/dockerfiles
that are intended to provide well defined environments for doing
test builds. We want our CI system to use these containers too.

This introduces builds of all of them as the first stage in the
CI, so that the built containers are available for later build
jobs. The containers are setup to use the GitLab container
registry as the cache, so we only pay the penalty of the full
build when the dockerfiles change. The main qemu-project/qemu
repo is used as a second cache, so that users forking QEMU will
see a fast turnaround time on their CI jobs.

This will also provide those chars via recv() as

ConsoleSocket also has the option of dumping
the console bytes to a log file.

We also give QEMUMachine the option of using ConsoleSocket
to drain and to use for logging console to a file.
By default QEMUMachine does not use ConsoleSocket.

Robert Foley 13336606a5 tests/vm: Added a new script for ubuntu.aarch64.
ubuntu.aarch64 provides a script to create an Ubuntu 18.04 VM.
Another new file is also added aarch64vm.py, which is a module with
common methods used by aarch64 VMs, such as how to create the
flash images.

Robert Foley e56833b48b tests/vm: Add common Ubuntu python module
Add a common Ubuntu python module and make use of
it with the ubuntu.i386 script.
This is preparation for adding an Ubuntu script
ubuntu.aarch64.  Splitting out the common
logic such as build_image() will reduce duplication.

Robert Foley 3f1e8137f2 tests/vm: Added configuration file support
Changes to tests/vm/basevm.py to allow accepting a configuration file
as a parameter. Allows for specifying VM options such as
cpu, machine, memory, and arbitrary qemu arguments for specifying options
such as NUMA configuration.
Also added an example conf_example_aarch64.yml and conf_example_x86.yml.

Robert Foley 5d676197eb tests/vm: Add configuration to basevm.py
Added use of a configuration to tests/vm/basevm.py.
The configuration provides parameters used to configure a VM.
This allows for providing alternate configurations to the VM being
created/launched. cpu, machine, memory, and NUMA configuration are all
examples of configuration which we might want to vary on the VM being created
or launched.
This will for example allow for creating an aarch64 vm.

Robert Foley 995f5c3c32 util/coroutine: Cleanup start_switch_fiber_ for TSAN.
This is a cleanup patch to follow-up the patch which introduced TSAN.
This patch makes separate start_switch_fiber_ functions for TSAN and ASAN.

This does two things:
1. Unrelated ASAN and TSAN code is separate and each function only
   has arguments that are actually needed.
2. The co->tsan_caller_fiber and co->tsan_co_fiber fields are only
   access from within #ifdef CONFIG_TSAN.
