FreeBSD 13 Is Preparing To Finally Retire GCC 4.2

Phoronix - 14. Srpen 2019 - 11:36
GCC 4.2.1 has been out since 2007 and while there have been many big updates to the GNU Compiler Collection over the past decade, that version remains somewhat common in the BSD land due to being the last version under the GPLv2 license. GCC 4.2.2 and newer switched over to GPLv3+ and that is why several BSDs have stuck to using GCC 4.2.1 or at least keeping it in their base repository. But now for FreeBSD 13, this old version of GCC is set to be retired with FreeBSD already being quite focused on LLVM Clang as its default compiler while also offering newer GCC versions via its package management system...

Building The Default x86_64 Linux Kernel In Just 16 Seconds

Phoronix - 14. Srpen 2019 - 8:02
It's now been one week since the launch of AMD's EPYC Rome processors with up to 64 cores / 128 threads per socket and better IPC uplift compared to their previous-generation parts. Rome has outperformed Intel Xeon Scalable CPUs in their class while offering better power efficiency and way better performance-per-dollar. One of my favorite metrics has been how quickly the new EPYC 7742 2P can build the Linux kernel...

Softwarová sklizeň (14. 8. 2019) - 13. Srpen 2019 - 23:00
[1 minuta čtení] Sonda do světa otevřeného softwaru. Dnes budeme psát v terminálovém textovém editoru, pokusíme se rozchodit ne-nativní hry pomocí vrstev kompatibility, psát poznámky ve vimu a nakonec odešleme pár e-mailů. Terminálový editor pro vytváření a úpravu poznámek nebo psaní zdrojového kódu. Nabízí plnou podporu UTF-8, poradí si se zvýrazněním syntaxe, dokáže vyhodnocovat regulární výrazy pro vyhledávání a nahrazování textu, využívá také projekty třetích stran pro zpříjemnění práce a rozšíření vlastností (ctags, less, fzf, tree, grep, perl). Vlastní nápady lze do editoru integrovat pomocí Lua skriptů.

Cooling The Raspberry Pi 4 With The Fan SHIM & FLIRC For Better Performance

Phoronix - 13. Srpen 2019 - 20:30
With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device.

Intel's Linux Graphics Driver Developers Discover 3~20% Boost For Current-Gen Hardware

Phoronix - 12. Srpen 2019 - 23:48
Last week was the Intel Gallium driver one line patch to boost performance by 1%. Today's code churn within Mesa for Intel's open-source Linux graphics drivers were larger but also with a more profound performance impact with some workloads now being faster by around 20%. Making this more exciting is that today's round of driver optimizations apply to the very common and mature "Gen 9" graphics hardware...
