Tales from Linux Kernel 3.11 Development

Filed under

Linus torvalds announced the release of the 3.11-rc1 kernel, noting that it had been two weeks and “the merge window [period of time early in a release cycle during which disruptive kernel changes are permitted] has closed”.

According to Linus, “[this] merge window was smaller in terms of number of commits than the 3.10 merge window, but we actually have more new lines [of code]. Most of that seems to be in staging [a part of the kernel for new driver code] – a full third of all changes by line-count is staging, and merging in Lustre is the bulk of that”. This was followed by an RC2 that added “unnamed temporary files” (O_TMPFILE) – we’ll write about this in a later issue – and (a late change) new handling for backlights on systems designed to run Windows 8. Those systems are intended not to use direct ACPI method calls to control the backlight but instead directly drive the backlight control in the graphics driver.

Radeon vs. Nouveau Open-Source Drivers On Mesa Git + Linux 4.9

For your viewing pleasure this Friday are some open-source AMD vs. NVIDIA numbers when using the latest open-source code on each side. Linux 4.9-rc1 was used while Ubuntu 16.10 paired with the Padoka PPA led to Mesa Git as of earlier this week plus LLVM 4.0 SVN. As covered recently, there are no Nouveau driver changes for Linux 4.9 while we had hoped the boost patches would land. Thus the re-clocking is still quite poor for this open-source NVIDIA driver stack. For the Nouveau tests I manually re-clocked each graphics card to the highest performance state (0f) after first re-clocking the cards to the 0a performance state for helping some of the GPUs that otherwise fail with memory re-clocking at 0f, as Nouveau developers have expressed this is the preferred approach for testing.

Ubuntu MATE, Not Just a Whim

I've stated for years how much I dislike Ubuntu's Unity interface. Yes, it's become more polished through the years, but it's just not an interface that thinks the same way I do. That's likely because I'm old and inflexible, but nevertheless, I've done everything I could to avoid using Unity, which usually means switching to Xubuntu. I actually really like Xubuntu, and the Xfce interface is close enough to the GNOME 2 look, that I hardly miss the way my laptop used to look before Unity. I wasn't alone in my disdain for Ubuntu's flagship desktop manager switch, and many folks either switched to Xubuntu or moved to another Debian/Ubuntu-based distro like Linux Mint. The MATE desktop started as a hack, in fact, because GNOME 3 and Unity were such drastic changes. I never really got into MATE, however, because I thought it was going to be nothing more than a hack and eventually would be unusable due to old GNOME 2 libraries phasing out and so forth. Read more
