VK_FORMAT_FEATURE_TRANSFER_[SRC|DST]_BIT_KHR is a flag value of the
VkFormatFeatureFlagBits enum that can only be hold and checked against
the linearTilingFeatures or optimalTilingFeatures members of the
VkFormatProperties struct but not the bufferFeatures member.
>From the Vulkan® 1.0.51, with the VK_KHR_maintenance1 extension,
section 32.3.2 docs for VkFormatProperties:
"* linearTilingFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by images created with a tiling
parameter of VK_IMAGE_TILING_LINEAR.
* optimalTilingFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by images created with a tiling
parameter of VK_IMAGE_TILING_OPTIMAL.
* bufferFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by buffers."
...
Bits which can be set in the VkFormatProperties features
linearTilingFeatures, optimalTilingFeatures, and bufferFeatures
are:
typedef enum VkFormatFeatureFlagBits {
...
VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR = 0x00004000,
VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR = 0x00008000,
...
} VkFormatFeatureFlagBits;
...
The following bits may be set in linearTilingFeatures and
optimalTilingFeatures, specifying that the features are supported
by images or image views created with the queried
vkGetPhysicalDeviceFormatProperties::format:
...
* VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR specifies that an image
can be used as a source image for copy commands.
* VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR specifies that an image
can be used as a destination image for copy commands and clear
commands."

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see https://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
