** Description changed: [Impact] This is needed for some new AMD RDNA4 platforms that require the newer llvm for runtime shader compilation. Skipping oracular, as it is going to be EOL soon. Note that llvm-toolchain-20 needs to be built twice on noble, first without llvm-spirv-20 which doesn't exist yet, and then after spirv- llvm-translator-20 has built, it's built a second time *with* llvm- spirv-20 which is needed to build libclc-20 which Mesa needs. [Test case] - Check that drivers that require llvm still work, including swrast - (llvmpipe), radeonsi. + Install updates, check that drivers that require llvm still work, + including swrast (llvmpipe), radeonsi. Test with normal desktop usage, glxgears, glmark2, Unigine demos. That - should give enough confidence. + should give enough confidence that things still work. [Where things could go wrong] The new llvm version might result in buggy behaviour with the swrast/radeonsi drivers.
