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".

  • Open education: How students save money by creating open textbooks
    Most people consider a college education the key to future success, but for many students, the cost is insurmountable. The growing open educational resource (OER) movement is attempting to address this problem by providing a high-quality, low-cost alternative to traditional textbooks, while at the same time empowering students and educators in innovative ways. One of the leaders in this movement is Robin DeRosa, a professor at Plymouth State University in New Hampshire. I have been enthusiastically following her posts on Twitter and invited her to share her passion for open education with our readers. I am delighted to share our discussion with you.

Linux 4.10 To Linux 4.15 Kernel Benchmarks

The ThinkPad X1 Carbon has been enjoying its time on Linux 4.15. In addition to the recent boot time tests and kernel power comparison, here are some raw performance benchmarks looking at the speed from Linux 4.10 through Linux 4.15 Git. With this Broadwell-era Core i7 5600U laptop with 8GB RAM, HD Graphics, and 128GB SATA 3.0 SSD with Ubuntu 17.10 x86_64, the Linux 4.10 through 4.15 Git mainline kernels were benchmarked. Each one was tested "out of the box" and the kernel builds were obtained from the Ubuntu Mainline Kernel archive. Read more
