Radeon R300 Driver Lands NIR-To-TGSI Code, Old NVIDIA Driver Eyes It Too

Sat, 12/11/2021 - 03:48
The open-source Radeon Linux graphics driver work covered yesterday about a big optimization by leveraging NIR and going through that intermediate representation and relying on common NIR optimizations has now been merged into Mesa 22.0. This is a step-up from the existing open-source OpenGL driver support for old Radeon 9500 through Radeon X1000 series (R500) graphics processors. A similar conversion is also planned for the old Nouveau driver handling NVIDIA "NV30" era graphics processors too...

Benchmarks: FreeBSD 13 vs. NetBSD 9.2 vs. OpenBSD 7 vs. DragonFlyBSD 6 vs. Linux

Fri, 12/10/2021 - 22:30
It's been a while since last having a hearty BSD benchmark comparison on Phoronix in part due to the latest hardware platforms generally lagging behind with how well supported they are by the various BSDs. But stemming from a Phoronix Premium supporter recently requesting some fresh BSD benchmarks, here is a look at how DragonFlyBSD 6.0.1, FreeBSD 13.0, NetBSD 9.2, and OpenBSD 7.0 are competing against various Linux distributions like CentOS, Clear Linux, and Ubuntu.

Developers Call On Intel To Open-Source PSE Firmware As Their Newest Binary Headache

Fri, 12/10/2021 - 21:38
With Intel's Atom x6000E "Elkhart Lake" SoCs there is a new block called the Programmable Services Engine (PSE) that is an Arm Cortex-M7 companion core that handles various tasks. Unfortunately, with the PSE it means a new binary-only firmware module. With the Programmable Services Engine likely to come with future Intel platforms too, Coreboot developers and open-source enthusiasts are calling on Intel to now open-source this firmware to avoid having this extra binary blob and further complicating future open-source firmware efforts...

Restartable Sequences "RSEQ" Support Returning To GNU C Library

Fri, 12/10/2021 - 19:04
Back in 2018 for the Linux 4.18 kernel was introducing the Restartable Sequences system call for allowing faster user-space operations on per-CPU data. By avoiding atomic operations in cases like incrementing per-CPU counters, modifying per-CPU spinlocks, reading/writing to per-CPU ring buffers, and similar, Restartable Sequences can provide a performance advantage. The GNU C Library is landing its revised support for making use of this system call...
