While the adding and removing of data from this global linked list
was guarded, GetInstanceProcAddr & GetDeviceProcAddr did not have
such guards. This results in race conditions that were detected with
thread sanitizer. This commit adds a mutex solely for the
loader.instances global variable.
Many tests were using the V6 TestICD, which means that it exports the
EnumerateAdapterPhysicalDevices. The loader then only looks for devices
using that functionality and if the test didn't set it up, the driver
won't have its devices found.
Also:
* Cleaned up handle_validation_tests
* Added WSI setup helpers, which put all the setup code for WSI in one place
* Created a to/from_nondispatch_handle function for TestICD, probably should
be in a more general location
Test fixturing (TEST_F) is useful when there is a lot of common code that needs
to be run for a suite of tests. However, the FrameworkEnvironment encapsulates
almost all of the setup work all tests needs, and so doesn't need to be in a
fixture. Making the add_icd call inside the tests makes it clear which binary
is being used.
This commit also uses the corrent signed/unsigned constants in tests, as was
warned by compilers when enhanced warnings were enabled (/W4 in msvc).
Move all the behavior found in child classes of FrameworkEnvironment to the
FrameworkEnvironment itself, allowing easier composibility of behavior. The
original idea was to allow special case behavior for specific test cases but
this resulted in a lot of code duplication and difficulty combining different
framework behavior, such as adding a fake ICD and setting VK_ICD_FILENAMES at
the same time.
Warnings/fixes include:
* strcpy/strncpy/wstrcpy
* Dropping static on inline functions
* Use localtime_s
* Name shadowing
* Use wcstombs_s
* 32<->64 bit int conversion
* Silence spurious C4996 generated in vs2015
Made InstanceWrapper and DeviceWrapper simpler to use by moving them to test_environment
then making the Create() member functions and doing the gtest assertions in the function
itself.
Additionally:
Removed the `detail` namespace in the test_environment.
Renamed get_new_test_icd/layer to just `reset_icd/layer`. This is clearer about what it
is doing and makes the interface more expressive with code such as
`env->reset_icd().SetMinInterfaceVersion(5);`
Requires adding ability for device to return functions with
vkGetDeviceProcAddr that aren't necessarily useable functions.
Also added checks to make sure that the handle passed in by the loader
to the TestICD is the 'right handle' where necessary, as some functions
do not need to know which device is being called on, just that it is correct.
