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
Since the loader is meant to be forward compatible, it makes little sense to emit
a warning when an ICD or Layer manifest is found with a version that it doesn't
understand. Thus they now are INFO level.
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).
Add "additive" environment variables for adding additional layer
paths or driver JSON files instead of replacing default ones.
Also, rename VK_ICD_FILENAMES to VK_DRIVER_FILES since we're trying
to remove references to ICDs because software driver implementations
of Vulkan aren't ICDs (but continue to support the old name as well).
Added documentation around these changes to reflect the new name and
the new variables.
The loader trampoline previously would query all devices every time
vkEnumeratePhysicalDevices was called.
To do this, it would make two calls every time:
- First, it would ignore the passed in user values
- Second, it would query the total number of available devices.
- Third, it would query the values for every available device
This resulted in layers reporting 2 vkEnumeratePhysicalDevices call for
every 1 the application made which could get very polluted in output.
It didn't break any functionality, just made things messy.
This change removes that behavior and adds a bunch of test cases to verify
nothing broke in the move.
The 1.2.175 header release saw the addition of API Variants. For the purposes
of the loader, this should always be set to 0. If this value isn't zero, the
loader should warn about it.
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);`
Since the loader only uses environment variables if the process is
not running with elevated priviledges, the test harness needs to be
able to control that aspect to ensure consistency as CI systems may
run the tests in an 'elevated' context.

Move windows specific error reporting to test_util.h
This allows for its use anywhere its required.

These files are the current 4 source code files used to create the
regression test suite
loader_regression_tests.cpp and loader_version_tests.cpp contain a
majority of the tests.
loader_wsi_test.cpp is all the tests pertaining to the WSI functions
in the loader.
loader_testing_main.cpp contains the `main()` which has windows CRT
specific calls to disable popups and debug aserts.
There are two executables created, test_regression and test_wsi.
test_regression is both regression_tests and version_tests. test_wsi
is the WSI tests. These tests are separate as they rely on linking
with platform specific windowing libraries which may not be present
on a CI system.
