Mesa 11.2 Released


Mesa 11.2.0 has just been released.  Mesa started life many years ago as an open source (MIT License) implementation of the OpenGL graphics API.  Over the years the Mesa project has implemented several other APIs such as OpenVG and OpenGL ES.  Mesa has also become a steward of sort for open source graphic driver implementations shown here.  Another common usage scenario for Mesa is the software layer, that allowed compatibility with accelerated graphics on non accelerated hardware.


Enough with what Mesa is, and back to the release.  Details of the 11.2 release:

- CI   - Add Travis-CI configuration file.    - Documented more environment variables, squashed a ton of typos.    - Core mesa   - Fix locking of GLsync objects.   - Ongoing work for GL_OES_geometry_shader support    - GLSL   - Massive amount of fixes - ubo/ssbo amongst others.   - Significant rework in preparation for GL_ARB_enhanced_layouts support.    - GL   - Reduced binary size (by about 15%)    - Nine   - Various fixes - multithreading, rounding issues, honour alignments, etc.    - WGL   - Add support for WGL_ARB_render_texture    - OSMesa (both classic and gallium)   - Add new OSMesaCreateContextAttribs() API    - EGL   - Android: Add ANDROID_framebuffer_target and ANDROID_recordable support.   - Wayland: Try to use wl_surface.damage_buffer for SwapBuffersWithDamage   - X11: Fixed a number of crashes            Video backends:  - OMX   - Correct the timestamping during video decoding    - VAAPI   - Disable MPEG4 by default   - Make the implementation thread safe   - Add BOB/motion adaptive deinterlacing      Drivers:  - i965   - Add more KBL PCI IDs   - Fleshed out libi965_compiler in preparation for Vulkan support    - llvm   - POWER8 optimised codepaths    - nouveau   - Renamed various symbols to follow the naming scheme used by Nvidia.   - Updated against the new nouveau UAPI   - Initial support for GM20x GPUs   - Added a nouveau backend for st/va   - Ongoing work towards compute shaders support   - More performance counters work - added SM30 (Kepler), removed unused ones.    - radeon(s)   - Dropped support for LLVM 3.5. LLVM 3.6 or later is required   - ETC support for Stoney   - Disable MPEG1 (UVD)   - Big endian fixes    - svga   - Avoid emitting redundant commands - SetIndexBuffer, SetVertexBuffers   - Increase the fence timeout    - virgl   - Add virtio 1.0 PCI IDs      Platform specific:  - Android   - Added virgl to the build   - Handle secondary arch on mixed 32/64bit builds, ARM64 support   - Fixes when building for SSE 4.1 capable CPU   - Various compatibility fixes for AOSP build system rework    - UNIX   - DragonFly support/fixes   - Removed hardcoded link libraries references (-ldl, -lpthread)   - Check for correct python binary name.    - Windows   - Visual Studio 2013 or later is now required      This release adds support for the following extensions:    - GL_ARB_arrays_of_arrays on all gallium drivers that provide GLSL 1.30  - GL_ARB_base_instance on freedreno/a4xx  - GL_ARB_compute_shader on i965  - GL_ARB_copy_image on r600  - GL_ARB_indirect_parameters on nvc0  - GL_ARB_query_buffer_object on nvc0  - GL_ARB_shader_atomic_counters on nvc0  - GL_ARB_shader_draw_parameters on i965, nvc0  - GL_ARB_shader_storage_buffer_object on nvc0  - GL_ARB_tessellation_shader on i965 and r600 (evergreen/cayman only)  - GL_ARB_texture_buffer_object_rgb32 on freedreno/a4xx  - GL_ARB_texture_buffer_range on freedreno/a4xx  - GL_ARB_texture_query_lod on freedreno/a4xx  - GL_ARB_texture_rgb10_a2ui on freedreno/a4xx  - GL_ARB_texture_view on freedreno/a4xx  - GL_ARB_vertex_type_10f_11f_11f_rev on freedreno/a4xx  - GL_KHR_texture_compression_astc_ldr on freedreno/a4xx  - GL_AMD_performance_monitor on radeonsi (CIK+ only)  - GL_ATI_meminfo on r600, radeonsi  - GL_NVX_gpu_memory_info on r600, radeonsi
