AMD EPYC vs. Intel Xeon Cascadelake With Facebook's RocksDB Database

Following the benchmarks earlier this month looking at PostgreSQL 12.0 on AMD EPYC Rome versus Intel Xeon Cascade Lake there was interest from Phoronix readers in wondering how well Rome is doing for other modern enterprise database workloads. One of those workloads that was recently added to the Phoronix Test Suite / OpenBenchmarking.org is Facebook's RocksDB, the company's embedded database that is forked from Google LevelDB. With RocksDB being designed to exploit many CPU cores and modern SSD storage, here are some benchmarks looking at how the Xeon Platinum 8280 stacks up against various new AMD EPYC 7002 series processors.

A Vast Majority Of Linux's Input Improvements Are Developed By One Individual

While there is an ever increasing number of open-source developers focusing on the Linux graphics stack with the GPU drivers and related infrastructure, it's quite a different story when it comes to the Linux input side. It's basically one developer that has been working on the Linux input improvements for the past number of years.

LLVM Clang RISC-V Now Supports LTO

With the recent release of LLVM 9.0 the RISC-V back-end was promoted from an experimental CPU back-end to being made "official" for this royalty-free CPU ISA. Work though isn't over on the LLVM RISC-V support with new features continuing to land, like link-time optimizations (LTO) most recently being enabled within the Clang 10 code.

Linux Graphics Drivers Could Have User-Space API Changes More Strictly Evaluated

User-space API additions and changes (granted, no ABI breakage permitted for the mainline Linux kernel) to Linux Direct Rendering Manager (DRM) drivers is done fairly easily by their developers and possibly without enough thought. Linux DRM subsystem co-maintainer David Airlie has issued a proposal that would make user-space API alterations more strictly reviewed.

Vulkan To Better Handle Variable Rate Displays / Adaptive-Sync In The Future

While longtime X11 developer Keith Packard is now working for SiFive on RISC-V processors by day, he's still involved in the Linux graphics world through his contract work for Valve. At the XDC2019 conference earlier this month he presented on display timing, the current Linux plumbing for it, and also bringing up Vulkan will better support variable rate displays in the future.

GNOME's Mutter 3.35.1 Fixes The Night Light Mode On Wayland

With many of the prominent fixes that we've talked about for GNOME Shell and Mutter since last month's 3.34 release having been back-ported to 3.34.1, this weekend's release of GNOME Shell 3.35.1 and Mutter 3.35.1 as the first steps towards GNOME 3.36 aren't all that big. But at least in the case of this new Mutter development release are some worthwhile fixes.
