Some notes about driver bugs encountered:
AMD amdvlk on Linux, as tested with Ubuntu 19.10 and 20.04-LTS:
NO relevant bugs since/as of the release of the 2020-Q2.6 driver in July 2020.
Now supports HDR-10 with 10 bpc output precision properly in direct display mode.
New bugs:
* HDR color gamut parsing is broken AGAIN! Now all chroma coords are too low
by a factor 5. Workaround implemented in PsychVulkanCore to multiply by 5x.
* If one switches multiple displays/RandR outputs into direct-display-mode then
that works, but when one tries to close them again / release the displays:
- If each RandR output / VKDisplay is on its own X-Screen all is fine.
- If the outputs/VKDisplays are on the same X-Screen (multi-display, single X-Screen)
then the driver fails to release all but the last/most recently acquired display!
All others get stuck at their last image, until one acquires/releases that one
display again. Peculiar: Even quitting Octave doesn't release the display!!
* Oh yeah, and while radv does do switching of a direct-display-mode display
into the requested mode, amdvlk ignores this and always switches to the
highest capability mode! Bad if the highest mode is also flaky due to
low link signal quality -- Displays blank out, DP link training fails etc.
--> ALL shoddy but work(around)able as of 2020-Q2.6
Before that release there were various serious bugs for which i
provided bug fixes, and one bug report fixed by AMD themselves:
- Failure of RandR output --> VKDisplayKHR mapping in error handling and on repeat calls.
- Failure of RandR output leasing --> Bugs in the build process, and other bugs.
- Failure in DirectDisplayMode to provide any displayable pixel formats!
- Failure in DirectDisplayMode to provide > 8 bpc formats.
- Errors in HDR display colorimetry property queries.
- Failure to allow setting HDR metadata for the display in RandR output leased mode.
Mesa RADV:
Can only handle one direct mode display (driver limitation).
However if one tries to open a 2nd display on another driver like amdvlk,
then radv doesn't fail gracefully. While 2nd display on amdvlk works, the
1st display handled by radv gets stuck and the swapchain reports failure
to present with some error code.
Tested AMD gpu's for HDR et al:
Discrete Advanced Micro Devices, Inc. [AMD/ATI] - Baffin [Radeon RX 460/560D / Pro 450/455/460/555/555X/560/560X] GPU found.
AMD Radeon RX graphics (Polaris11). DCE 11.2 Polaris family.
Integrated: AMD Raven Ridge DCN1.
Windows-10:
AMD: As of Radeon software release 2020.4.2 (June 2020)
- Failure in HDR display colorimetry property queries. Misreports maxLuminance and
maxFALL: maxFALL not reported at all (ie. zero), maxLuminance misreported as what
should be maxFALL. Reported to AMD months ago, not fixed.
- In fullscreen exclusive mode, surface properties report maxLayers == 0, which is
an impossible value, and leads to validation layers falsely reporting application
bugs. Ie. VkSurfaceCapabilities2KHR.surfaceCapabilities.maxImageArrayLayers == 0.
- Switching to fullscreen exclusive mode works with Matlab (compiled with MSVC2019),
but not with Octave 5.1/5.2 (MinGW64) for unknown reasons. VK_ERROR_INITIALIZATION_FAILED.
- Trying to display a VKSurface on any display not attached to the AMD gpu, but to
a different gpu (in my case, NVidia GeForce GTX-1650) leads to a amd driver crash,
not only in fullscreen exclusive mode, but even in regular windowed mode, when
displaying into a Window on the regular Windows-10 desktop, just located on a
different gpu's monitor!

- Control of local backlight dimming on a FreeSync-2 HDR certified monitor via
VkDisplayNativeHdrSurfaceCapabilitiesAMD does not work, despite the extension
reporting that the monitor supports control. Don't know if this is an AMD
driver bug, or monitor firmware bug.
- Calling vkCreateInstance() after an OpenGL context was created, instead of before, somehow
damages the OpenGL context in a way that causes any OpenGL glXXX() to crash the AMD OpenGL
driver. Even trying to unbind an OpenGL context will crash the driver!

Querying HDR display colorimetry/HDR metadata from within Vulkan via
vkGetPhysicalDeviceSurfaceCapabilities2KHR() with .pNext chained VK_STRUCTURE_TYPE_HDR_METADATA_EXT
struct fails. Works on AMD on both Windows and Linux.
Needed to implement a fallback using MS-Windows 10 DXGI v1.6.
Displaying in HDR-10 windowed mode sometimes gets the display stuck in HDR-10
permanently, even across system reboots. One needs to manually disable in Windows-10
display settings.
