In traditional multisampled framebuffer rendering, color samples must be explicitly resolved via BlitFramebuffer before doing the scaled blitting of the framebuffer. So, scaled blitting of a multisample framebuffer takes two separate calls to BlitFramebuffer. This patch implements the functionality of doing multisampled scaled resolve using just one BlitFramebuffer call. Important changes involved in this patch are listed below: - Use float registers to scale and offset texture coordinates. - Change offset computation to consider float coordinates. - Round the scaled coordinates down to nearest integer. - Modify src texture coordinates clipping to account for scaling.. - Linear filter is not yet implemented in blorp. So, don't use blorp engine to do single sampled scaled blitting. V3: Fix nearest filtering issue in scaled blits. Makes failing piglit fbo-blit-stetch test and framebuffer_blit_functionality_magnifying_blit.test in gles3 CTS pass. Observed no piglit, gles3 CTS regressions on sandybridge & ivybridge with this patch. Signed-off-by: Anuj Phogat <anuj.phogat@gmail.com> Reviewed-by: Paul Berry <stereotype441@gmail.com> |

File: docs/README.WIN32 Last updated: 23 April 2011 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or 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. 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.
