Secure Boot isn't the only problem facing Linux on Windows 8 hardware

Filed under

There's now no shortage of Linux distributions that support Secure Boot out of the box, so that's a mostly solved problem. But even if your distribution supports it entirely you still need to boot your install media in the first place.

Hardware initialisation is a slightly odd thing. There's no specification that describes the state ancillary hardware has to be in after firmware→OS handover, so the OS effectively has to reinitialise it again. This means that certain bits of hardware end up being initialised twice, and that's slow in some cases. The most obvious is probably USB, which has various timeouts as you wait for hardware to settle. Full USB support in the firmware probably adds a couple of seconds to boot time, and it's arguably wasted because the OS then has to do the same thing (but, thankfully, can at least do other things at the same time). So, looking for USB boot media takes time, and since the overwhelmingly common case is that users don't want to boot off USB, it's time that's almost always wasted.

One of the requirements for Windows 8 certified hardware is that it must complete firmware initialisation within a specific amount of time, something that Microsoft refer to as "Fast Boot".

  • Why leading DevOps may get you a promotion
    Gene Kim, author of The Phoenix Project and leading DevOps proponent, seems to think so. In a recent interview with TechBeacon's Mike Perrow, Kim notes that of "the nearly 100 speakers at DevOps Enterprise Summits over the last two years, about one in three have been promoted."

    SWORDY is a rather fun looking local party brawler that has just released on Steam in Early Access. It could see a Linux release too, if Microsoft allow it.
  • System Shock remake has blasted past the Linux stretch goal, officially coming to Linux
    The Linux stretch goal was $1.1 million and it's pleasing to see it hit the goal, so we won't miss out now. I am hoping they don't let anyone down, as they have shown they can do it already by providing the demo. There should be no reason to see a delay with Linux now.
  • GammaRay 2.5 release
    GammaRay 2.5 has been released, the biggest feature release yet of our Qt introspection tool. Besides support for Qt 5.7 and in particular the newly added Qt 3D module a slew of new features awaits you, such as access to QML context property chains and type information, object instance statistics, support for inspecting networking and SSL classes, and runtime switchable logging categories.

    KDAB has announced the release of GammaRay 2.5, what they say is their "biggest feature release yet", the popular introspection tool for Qt developers.

    After implementing the new redesigned Shell of GNOME Control Center, it’s now time to move the panels to a bright new future. And the Keyboard panel just walked this step.
  • Debian on Seagate Personal Cloud and Seagate NAS
    The majority of NAS devices supported in Debian are based on Debian's Kirkwood platform. This platform is quite dated now and can only run Debian's armel port. Debian now supports the Seagate Personal Cloud and Seagate NAS devices. They are based on Marvell's Armada 370, a platform which can run Debian's armhf port. Unfortunately, even the Armada 370 is a bit dated now, so I would not recommend these devices for new purchases. If you have one already, however, you now have the option to run native Debian.
