Kernel: Retbleed Woes and Turnip Status Update

There's another great reason to update to 64-bit Linux now | TechRadar [Ed: No, this is actually a reason to abandon x86 (among other reasons)]
Anyone still considering whether to update to 64-bit Linux kernels (opens in new tab) now has another big motivation after it was revealed 32-bit editions won’t be getting a major security fix.
Intel’s Pawan Gupta recently took to the lore.kernel.org mailing list to answer customer questions, one of which concerned the fix to Retbleed for 32-bit OS’.
"Intel is not aware of production environments that use 32-bit mode on Skylake-gen CPUs. So this should not be a concern.” Intel’s Peter Zijlstra chimed in to add: "Yeah, so far nobody cared to fix 32-bit. If someone *realllllly* cares and wants to put the effort in I suppose I'll review the patches, but seriously, you shouldn't be running 32-bit kernels on Skylake / Zen based systems, that's just silly."

All of them have reasonable frame rate. However, there was a bit of “cheating” involved. Only “The Talos Principle” game was fully running on the development board (via box64), other two games were only rendered in real time on Adreno GPU, but were ran on x86-64 laptop with their VK commands being streamed to the dev board. You could read about this method in my post “Testing Vulkan drivers with games that cannot run on the target device”.

For Vulkan 1.3 conformance there are only a few extension left to implement. The only major ones are VK_KHR_dynamic_rendering and VK_EXT_inline_uniform_block required for Vulkan 1.3. VK_KHR_dynamic_rendering is currently being reviewed and foundation for VK_EXT_inline_uniform_block was recently merged.
