Following today's disclosure by Intel of the CrossTalk/SRBDS vulnerability that is MDS-based and vulnerable across physical cores with affected instructions, Intel released new CPU microcode to mitigate the most prone/significant instructions. I've been benchmarking the impact of this new microcode on multiple systems and will have a full report tonight or tomorrow morning... But here is a look specifically at the look at the impact on the RdRand performance...

Haiku, the nearly two decade old open-source operating system still preserving compatibility with BeOS, is out with its second beta release...

This morning I noted CrossTalk / SRBDS as the newest side-channel vulnerability following Intel's monthly security advisories being sent out. It turns out Intel broke their own embargo on the disclosure and I happened to spot it quickly before they retracted it. In the hours since, the university researchers behind this CrossTalk vulnerability reached out and have provided an embargoed copy of the whitepaper. As of now, the formal disclosure time has passed so information on this new side-channel Intel CPU vulnerability is public and it shows for the first time that speculative execution can enable attackers to leak sensitive information across physical cores on Intel CPUs.

The open-source Nouveau kernel driver has supported Volta GPUs for some time and since Linux 5.6 also supported open-source initialization of Turing GPUs for hardware acceleration. But missing for Volta and Turing has been the Mesa-side support for enabling 3D (OpenGL) and compute (OpenCL) functionality on these newer GPUs. That is finally changing with pending Mesa patches...

Out today is the RadeonSI OpenGL driver support for this next-generation Navi GPU...

While more laptops are shipping these days finally with Icelake "Gen 11" graphics and Tiger Lake with "Gen 12" graphics are expected soon, there still is an incredible amount of hardware out there making use of Intel Gen 9 graphics that have been in use since Skylake. It's looking like for the Ubuntu 20.10 cycle, there is going to be an emphasis on offering better performance for this very common generation of Intel UHD Graphics...

Normally the NTB patches for new kernel cycles aren't particularly noteworthy but this time around for Linux 5.8 is Icelake support...
