Further improvements have been done for OpenEmbedded ARMv8, where they replaced the php Apache module by php-fpm among other things. On the kernel side, USB drivers have been refactored, and a kernel size analysis have been performed on several platforms. The power management team has mainly worked on big.LITTLE IKS and MP implementations, and it’s the first time LEG (Linaro Enterprise Group) is included in the release, and they worked on UEFI for ARM, GRUB for U-Boot, and provided a Ubuntu server image for Arndale board which can boot via UEFI or UBoot. Here […]

LinuxCon North America 2012 Schedule

LinuxCon (North America) 2012 will take place on August 29 – 31, 2012 at Sheraton Hotel & Marina, in San Diego, California. The event will be co-located with the Linux Kernel Summit, the Linux Plumbers Conference, and CloudOpen 2012. LinuxCon consists of 3 days of keynotes, business and developers related sessions as well as tutorials. There will be over 80 sessions and keynotes during those 3 days. I’ll highlight a few sessions that I find particularly interesting and related to embedded Linux, software development and ARM. August 29 10:45 – 11:30 – Life After BerkeleyDB: OpenLDAP’s Memory-Mapped Database by Howard Chu, Symas Abstract: OpenLDAP’s new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy’s. Writes are on […]

Linux 3.3 Release

Linux Torvalds announced the release of Linux Kernel 3.3 on the 18th of March: So after the extra -rc release last weekend, now the final 3.3 is out there in the usual locations. Things did indeed calm down during the last week, and the shortlog looks pretty boring. The diffstat from -rc7 is dominated by the arch/tile defconfig changes, the rest is pretty small, although there are changes spread out in various subsystems (drivers, filesystem, networking, perf tools). … And obviously, the 3.3 release means that the merge window for 3.4 is now open, although I may keep of pulling stuff for a day or so to encourage people to test the actual release. Linux 3.2 brought ext-4 and btrfs file system improvements, support for Qualcomm Hexagon processor, an improved profiling tool (perf top), and better CPU and network bandwidth management. Linux 3.3 brings the following key changes: Android merge: […]

Online Petition Requesting to Allow Linux Installation on Windows 8 Devices

Back in September, some concerns emerged about UEFI secure boot requirement for Windows 8 and its possible consequences on Linux and other open source operating systems: it may be impossible to install such systems on computers or devices shipped with Windows 8, either by replacing Windows 8 or in a dual boot installation as the bootloader (UEFI) would prevent such installation for security reasons. Microsoft has already replied to those concerns and stated that: At the end of the day, the customer is in control of their PC. … We work with our OEM ecosystem to provide customers with this flexibility. The security that UEFI has to offer with secure boot means that most customers will have their systems protected against boot loader attacks. For the enthusiast who wants to run older operating systems, the option is there to allow you to make that decision. So there should be an […]

UEFI Secure Boot – Windows 8 vs Linux

Last week, Microsoft showcased Windows 8 PCs with super fast boot thanks to the Unified Extensible Firmware Interface (UEFI). The latest UEFI standard, released on April 8, includes a secure boot protocol which will be required for Windows 8 clients. Secure UEFI is intended to thwart rootkit infections by requiring keys before allowing executables or drivers to be loaded onto the device. Problem is, such keys can also be used to keep the PC’s owner from wiping out the current OS and installing another option such as Linux. It all started with slide 11 in one Powerpoint presentation entitled “Delivering a secure and fast boot experience with UEFI” presented by Arie van der Hoeven, Principal Lead Program Manager Microsoft Corporation during Build conference: Secure boot Current issues with boot Growing class of malware targets the boot path Often the only fix is to reinstall the operating system UEFI and secure […]
