AMD Zen 2 "Znver2" Compiler Optimizations Back-Ported For GCC 9.2 Compiler

Tuesday 30th of July 2019 10:51:46 AM
Last week I wrote about the GCC 10 compiler picking up a new scheduler model and cost tables for AMD Zen 2 CPUs to build off the initial "znver2" microarchitecture target from last year. Fortunately, those Znver2-specific improvements have now been back-ported to the GCC 9 compiler branch so it will see user systems with not as long of a wait until GCC 10 stable...

TurboSched Is A New Linux Scheduler Focused On Maximizing Turbo Frequency Usage

Monday 29th of July 2019 11:09:07 AM
TurboSched is a new Linux kernel scheduler that's been in development by IBM for maximizing use of turbo frequencies for the longest possible periods of time. Rather than this scheduler trying to balance the load across all available CPU cores, it tries to keep the priority tasks on a select group of cores while aiming to keep the other cores idle in order to allow for the power allowance to be used by those few turbo-capable cores with the high priority work...

KDE Frameworks 5.61, Applications 19.08 in FreeBSD

Recent releases were KDE Frameworks 5.61 and KDE Applications 19.08. These have both landed in the official FreeBSD ports tree, after Tobias did most of the work and I pushed the big red button. Your FreeBSD machine will need to be following current ports – not the quarterly release branches, since we don’t backport to those. All the modern bits have arrived, maintaining the KDE-FreeBSD team’s commitment to up-to-date software for the FreeBSD desktop. The one thing we’re currently lagging on is Qt 5.13. There’s a FreeBSD problem report tracking that update. Read more

Dev branch moving towards Qt 6

As you know, Qt 5.14 will be branched pretty soon. After that I would expect that most new development work would start to be aimed towards Qt 6. As it looks right now, 5.15 will be a smaller release where we polish what we have in 5.14, and prepare some things for Qt 6. To reflect that and help us all understand that the development focus is now towards Qt 6, I would like to propose that dev becomes the Qt 6 branch after we branched away 5.14 (and we merge wip/qt6 back into dev). We can then either create a 5.15 branch at the same time, or slightly later, once 5.14 has stabilised a bit more (e.g. after the beta or RC).
