Intel Xeon Platinum 8380 P-State CPU Frequency Scaling Comparison

Phoronix - Mon, 06/07/2021 - 23:46
As part of the curiosity-driven benchmarks and areas of technical interest now that we've gotten some of our initial Intel Xeon Platinum 8380 "Ice Lake" benchmarks out of the way has been looking into the performance of Linux's P-State CPU frequency scaling driver on the 3rd Gen Xeon Scalable server. Benchmarked for the latesting testing was the power/efficiency out-of-the-box with P-State powersave as used by default with many Linux distributions against the P-State "performance" mode as well as putting P-State into passive mode to be able to via intel_cpufreq to try the Schedutil governor that relies on the kernel's scheduler utilization data for making frequency scaling decisions. Here is a number of power/performance governor benchmarks with the dual Xeon Platinum 8380 server in these varying kernel configurations.

Open-Source Driver Flips On OpenGL ES 3.1 For Select NVIDIA GeForce 200 Series GPUs

Mesa's Direct3D 12 driver maintained by Microsoft as part of their WSL and Windows OpenGL-over-D3D12 efforts has added a means of being able to select between multiple GPUs/adapters...

Qt 6.2 Enters Feature Freeze With More Qt5 Modules Ported To Qt6

Phoronix - Mon, 06/07/2021 - 18:08
While Qt 6.1 released just one month ago, Qt 6.2 as of today is already into its feature freeze. This quicker than normal time to feature freeze comes due to this year's Qt releases being tightened up following the Qt 6.0 debut at the end of last year. Qt 6.2 will be the first Long Term Support (LTS) release of the Qt6 series...

Linux 5.14 To Allow EXT4 Journal Checkpoints From User-Space For Extra Privacy

Phoronix - Mon, 06/07/2021 - 17:51
Queued up now into the EXT4 file-system's "dev" tree is the recent work on a journal checkpoint ioctl (EXT4_IOC_CHECKPOINT) and optional support for TRIM/discard or zero-out support on journal flushes. This is the work that came about in recent months in working to ensure the privacy of deleted file names from the system...
