Red Hat engineer Jocelyn Falempe has been working to sort out DRM Panic support for the AMDGPU driver. The DRM Panic infrastructure is useful since it's what allows presenting a panic screen, a.k.a. a "Blue Screen of Death" type experience when running into major kernel problems. With Linux 6.12 there's now the ability to show QR codes for error messages with DRM Panic...

Last week when kicking off the Intel Granite Rapids benchmarking with the Xeon 6980P processors there was particularly strong performance within HPC and other scientific computing workloads. Besides going now up to 128 cores / 256 threads per socket, another reason for the especially strong generational uplift and against the current AMD EPYC competition is Xeon 6 Granite Rapids introducing Multiplexed Rank memory support. One of the areas I've been eager to explore is quantifying the DDR5-6400 vs. MRDIMM 8800MT/s performance difference and this article is dedicated to looking at that memory performance impact for the Xeon 6900P series.

Last week with the launch of the Intel Xeon 6900P "Granite Rapids" processors, Intel didn't disclose their list prices... Today they added the Granite Rapids list prices to their ARK database. With Granite Rapids making Intel much more competitive to the AMD EPYC competition and over prior generation Xeon CPUs, these new processors are commanding a higher price tag with the Xeon 6980P topping out at $17,800 USD...

After years of AmpereComputing talking about AmpereOne AArch64 server processors, it looks like we are finally on the cusp of seeing broader availability of the processors and servers/motherboards for this ARM server platform up to 192 cores. At the end of August I finally received a temporary review system with the AmpereOne A192-32X flagship SKU. That server was the Supermicro ARS-211M-NR and is supposed to be seeing availability real soon. Now the latest on the AmpereOne front is Giga Computing (Gigabyte) announcing general availability of their servers...

With the Intel Xeon 6900P "Granite Rapids" processors that launched last week there are SNC3 and HEX clustering modes for these new processors.

Using the flagship 128-core Intel Xeon 6980P processors, I ran some benchmarks looking at the real-world performance difference for SNC3 vs. HEX clustering modes on Granite Rapids.

While I have been very eager to test out the Core Ultra 200V Lunar Lake series on Linux in part due to the new Xe2 integrated graphics, after several days of pushing a new Lunar Lake laptop on Linux the results have been very disappointing. Besides needing a very leading-edge software stack to enjoy the Xe2 accelerated graphics out-of-the-box, the performance currently is poor. It's a fraction of the Windows performance and currently falls behind the Meteor Lake graphics performance and in turn also being well behind the AMD RDNA3.5 competition with the Ryzen AI 300 series laptops.

The newly-merged sched_ext allows for the Linux kernel scheduler to be made more extensible by allowing BPF programs to be loaded to affect the kernel's scheduling behavior. There's now a similar take on CPU frequency scaling: cpufreq_ext. There's a "request for comments" patch series on cpufreq_ext for making extensible CPU frequency scaling algorithm adaptations with BPF...
