From the Vulkan spec 1.0.32 section 29.6 docs for vkAcquireNextImageKHR: "Let n be the total number of images in the swapchain, m be the value of VkSurfaceCapabilitiesKHR::minImageCount, and a be the number of presentable images that the application has currently acquired (i.e. images acquired with vkAcquireNextImageKHR, but not yet presented with vkQueuePresentKHR). vkAcquireNextImageKHR can always succeed if a ≤ n - m at the time vkAcquireNextImageKHR is called. vkAcquireNextImageKHR should not be called if a > n - m with a timeout of UINT64_MAX; in such a case, vkAcquireNextImageKHR may block indefinitely." With minImageCount == 2 (as it was previously, the client is allowed to acquire all but one image withoutblocking. If we really need 4 images for mailbox mode + pageflipping, then we need to request a minimum of 4 images up-front. This is a bit unfortunate because it means we will always consume 4 images. In the future, we may be able to optimize this a bit by waiting until the server starts to flip and returning OUT_OF_DATE to get the client to re-allocate with more images or something like that.

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 http://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.
