OpenGL 274.5 is <strong>only</strong> available if requested at context creation 28because compatibility contexts are not supported. 29</p> 30 31 32<h2>SHA256 checksums</h2> 33<pre> 34e8d837a1cd55014e636e9caf6c75cfbe1b3e4be9ab3fa125f5ef38398aa12e97 mesa-17.2.7.tar.gz 3550cfdea8df55045797b4d0409591c04c784d9551c4da09b8178874dbe5a37a68 mesa-17.2.7.tar.xz 36</pre> 37 38 39<h2>New features</h2> 40<p>None</p> 41 42 43<h2>Bug fixes</h2> 44 45<ul> 46 47<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=94739">Bug 94739</a> - Mesa 11.1.2 implementation error: bad format MESA_FORMAT_Z_FLOAT32 in _mesa_unpack_uint_24_8_depth_stencil_row</li> 48 49<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=101378">Bug 101378</a> - interpolateAtSample check for input parameter is too strict</li> 50 51<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102006">Bug 102006</a> - gstreamer vaapih264enc segfault</li> 52 53<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102435">Bug 102435</a> - [skl,kbl] [drm] GPU HANG: ecode 9:0:0x86df7cf9, in csgo_linux64 [4947], reason: Hang on rcs, action: reset</li> 54 55<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102552">Bug 102552</a> - Null dereference due to not checking return value of util_format_description</li> 56 57<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102677">Bug 102677</a> - [OpenGL CTS] KHR-GL45.CommonBugs.CommonBug_PerVertexValidation fails</li> 58 59<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103098">Bug 103098</a> - [OpenGL CTS] KHR-GL45.enhanced_layouts.varying_structure_locations fails</li> 60 61<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103227">Bug 103227</a> - [G965 G45 ILK] ES2-CTS.gtf.GL2ExtensionTests.texture_float.texture_float regression</li> 62 63<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103393">Bug 103393</a> - glDispatchComputeGroupSizeARB : gl_GlobalInvocationID.x != gl_WorkGroupID.x * gl_LocalGroupSizeARB.x + gl_LocalInvocationID.x</li> 64 65<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103412">Bug 103412</a> - gallium/wgl: Another fix to context creation without prior SetPixelFormat()</li> 66 67<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103616">Bug 103616</a> - Increased difference from reference image in shaders</li> 68 69<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103626">Bug 103626</a> - [SNB] ES3-CTS.functional.shaders.precision</li> 70 71<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103732">Bug 103732</a> - [swr] often gets stuck in piglit's glx-multi-context-single-window test</li> 72 73<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103909">Bug 103909</a> - anv_allocator.c:113:1: error: static declaration of ‘memfd_create’ follows non-static declaration</li> 74 75<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=103966">Bug 103966</a> - Mesa 17.2.5 implementation error: bad format MESA_FORMAT_Z_FLOAT32 in _mesa_unpack_uint_24_8_depth_stencil_row</li> 76 77<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=104119">Bug 104119</a> - radv: OpBitFieldInsert produces 0 with a loop counter for Insert</li> 78 79<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=104143">Bug 104143</a> - r600/sb: clobbers gl_Position -> gl_FragCoord</li> 80 81</ul> 82 83 84<h2>Changes</h2> 85 86<p>Alex Smith (1):</p> 87<ul> 88 <li>radv: Add LLVM version to the device name string</li> 89</ul> 90 91<p>Andres Gomez (2):</p> 92<ul> 93 <li>docs: add sha256 checksums for 17.2.6</li> 94 <li>docs: remove bug 103626 from fix list as per 17.2.6</li> 95</ul> 96 97<p>Ben Crocker (2):</p> 98<ul> 99 <li>docs/llvmpipe.html: Minor edits</li> 100 <li>docs/llvmpipe: document ppc64le as alternative architecture to x86.</li> 101</ul> 102 103<p>Dave Airlie (1):</p> 104<ul> 105 <li>r600/sb: handle jump after target to end of program.
