Kernel Log: updated Radeon drivers, mdadm and ALSA

Filed under
Linux

AMD’s kernel and X.org developer Alex Deucher has published version 6.14.0 of driver package xf86-video-ati. It contains the X.org driver for Radeon graphics hardware, which provides much better support for the latest version of Radeon graphics chips. For example, it now not only controls the graphics kernel of the Fusion processors developed under codename "Ontario", but also the Northern Islands GPUs based on Radeon HD models 62xx to 68xx. With both of them, 2D acceleration via EXA now works, as does video acceleration with the antiquated Xv (Xvideo), but in both cases the driver remains dependant on Linux kernel 2.6.38, which is still under development and is expected to be released at the end of March or beginning of April. Its DRM driver with functions for KMS (kernel-based mode-setting) is required anyway for Northern Islands GPUs because the driver does not support UMS (user mode-setting) on these chips.

In combination with KMS in kernel 2.6.36 and later, the driver also supports EXA and Xv on Evergreen GPUs on Radeon HD 5,000 series models. The developers have considerably upgraded the man page in the new version. Along with kernel 2.6.38, the driver offers page-flipping support so that image updates are more precisely synchronised with the start of frame re-draw. For further information on this new technology in Linux 2.6.38, see the first part of the series "Coming in 2.6.38".

How Linux became my job

I've been using open source since what seems like prehistoric times. Back then, there was nothing called social media. There was no Firefox, no Google Chrome (not even a Google), no Amazon, barely an internet. In fact, the hot topic of the day was the new Linux 2.0 kernel. The big technical challenges in those days? Well, the ELF format was replacing the old a.out format in binary Linux distributions, and the upgrade could be tricky on some installs of Linux. Read more

Linux 4.16-rc2

It's been a quiet week, and rc2 is out. I take the fairly quiet rc be a good sign for 4.16, but honestly, rc2 is often fairly calm. That's probably because people are taking a breather after the merge window, but also simply because it might take a while to find any issues. But let's be optimistic, and just assume - at least for now - that it's because all is well. The diffstat is fairly odd, but that often happens with small rc's just because then just a couple of pulls will skew things easily in one or two directions. This time the patch is about one third architecture updates (arm64, x86, powerpc), one third tooling (mostly 'perf') and one third "rest". And yes, the bulk of that rest is drivers (gpu, nvme, sound, misc), but those drivers are still distinctly *not* the bulk of the whole patch. Go out and test, it all looks fine.

OpenStreetMap in IkiWiki and Why OpenStreetMap is in Serious Trouble

  • OSM in IkiWiki
    Since about 15 years ago, I have been thinking of creating a geo-referenced wiki of pubs, with loads of structured data to help searching. I don't know if that would be useful for anybody else, but I know I would use it! Sadly, the many times I started coding something towards that goal, I ended blocked by something, and I keep postponing my dream project.
  • Why OpenStreetMap is in Serious Trouble
    That said, while I still believe in the goals of OpenStreetMap, I feel the OpenStreetMap project is currently unable to fulfill that mission due to poor technical decisions, poor political decisions, and a general malaise in the project. I'm going to outline in this article what I think OpenStreetMap has gotten wrong. It's entirely possible that OSM will reform and address the impediments to its success- and I hope it does. We need a Free as in Freedom geographic dataset.

Linux KPI-Based DRM Modules Now Working On FreeBSD 11

Thanks to work done by Hans Petter Selasky and others, this drm-next-kmod port is working on FreeBSD 11 stable. What's different with this package from the ports collection versus the ported-from-Linux Direct Rendering Modules found within the FreeBSD 11 kernel is that these DRM modules are using the linuxkpi interface.
