Lenovo UEFI Bug Only Likes Windows and RHEL 162

New submitter Nagilum23 writes "It looks like Lenovo only knows of Windows and RHEL where their Thinkcentre M92p desktop is concerned. While investigating UEFI boot issues, Matthew Garrett found the PC's firmware actually checks the descriptive string for the operating system, and will prevent unlisted operating systems from booting. Garrett writes, 'Every UEFI boot entry has a descriptive string. This is used by the firmware when it's presenting a menu to users - instead of "Hard drive 0" and "USB drive 3", the firmware can list "Windows Boot Manager" and "Fedora Linux". There's no reason at all for the firmware to be parsing these strings. ... there is a function that compares the descriptive string against "Windows Boot Manager" and appears to return an error if it doesn't match. What's stranger is that it also checks for "Red Hat Enterprise Linux" and lets that one work as well. ... This is, obviously, bizarre. A vendor appears to have actually written additional code to check whether an OS claims to be Windows before it'll let it boot. Someone then presumably tested booting RHEL on it and discovered that it didn't work. Rather than take out that check, they then addded another check to let RHEL boot as well." Note that this isn't a SecureBoot issue. Lenovo is aware of the problem and looking into it.

Red Hat Developer Demands Competitor's Source Code 394

sfcrazy writes "A very serious argument erupted on the Linux kernel mailing list when Andy Grover, a Red Hat SCSI target engineer, requested that Nicholas A. Bellinger, the Linux SCSI target maintainer, provide proof of non-infringement of the GPL. Nick is developer at Rising Tide Systems, a Red Hat competitor, and a maker of advanced SCSI storage systems. Nick's company recently produced a groundbreaking technology involving advanced SCSI commands which will give Rising Tide Systems a lead in producing SCSI storage systems. Now, RTS is blocking Red Hat from getting access to that code as it's proprietary. What's uncertain is whether RTS' code is covered by GPL or not — if it is then Red Hat has all the rights to get access to it and it's a serious GPL violation."

Fully Open A13-OLinuXino Single-Board Linux Computer 111

Penurious Penguin writes "Via LXer, an article from PCWorld describes the A13-OLinuXino, produced by OLIMEX. Similar, but distinct from the Raspberry Pi, the Linux-powered OLinuXino is touted as 'fully open,' with all CAD files and source-code freely available for both personal and commercial reuse. Its specs include an Allwinner A13 Cortex A8 1GHz processor, 3D Maili400 GPU, 512MB RAM, all packed into a nano-ITX form and fit for operation in industrial environments between -25C and 85C. The device comes with Android 4.0, but is capable of running other Linux distros, e.g., ArchlinuxARM."

Oracle Makes Red Hat Kernel Changes Available As Broken-Out Patches 104

Artefacto writes "The Ksplice team has made available a git repository with the changes Red Hat made to the kernel broken down. They are calling this project RedPatch. This comes in response to a policy change Red Hat had implemented in early 2011, with the goal of undercutting Oracle and other vendors' strategy of poaching Red Hat's customers. The Ksplice team says they've been working on these individual patches since then. They claim to be now making it public because they 'feel everyone in the Linux community can benefit from the work.' 'For Ksplice, we build individual updates for each change and rely on source patches that are broken-out, not a giant tarball. Otherwise, we wouldn't be able to take the right patches to create individual updates for each fix, and to skip over the noise — like a change that speeds up bootup — which is unnecessary for an already-running system.'"

Project To Build Dual-Booting Linux, Android Tablet For $100 114

A reader sends this quote from Ars: "It likely won't be as sleek or fast as a Nexus 7 or Nexus 10, but a new tablet running both Android and Linux is in the works for open source enthusiasts and lovers of low-budget devices. PengPod tablets, made by a company called Peacock Imports, will dual-boot Android 4.0 and a version of Linux with the KDE Plasma Active interface for touch screens. But in order to reserve a tablet for yourself, you'll have to contribute to the company's crowdfunding project on Indiegogo and hope enough money is raised to begin production. 'Our goal is to build a powerful, True Linux Tablet, one free of Google and Android's restrictions, at a reasonable price,' the PengPod IndieGogo page says. 'If you're a Linux fanatic you probably ended up getting an Android phone. Hey, it's Linux right? It'll be open, run all the programs I'm familiar with and let me hack around and have some fun right? Too often, this is not so. That is why we set out to find a way to run real Linux and all the software you really want.'"

Ask Slashdot: Which Virtual Machine Software For a Beginner? 361

An anonymous reader writes "I am getting ready to start learning the use of virtual machines. What VM software would you recommend? This is for personal use. It would be good to run both Windows VMs and Linux VMs. Early use would be maintaining multiple Windows installs using only one desktop computer with plenty of cores and memory. I would be starting with a Windows host, but probably later switching to a Linux host after I learn more about it. Free is good, but reliability and ease of use are better. What is your preferred choice for a VM beginner? VMware? Xen? VirtualBox? Something else?" It may also be helpful if you can recommend particular VM software for particular uses, or provide some insight on different hosting options.

Cray Unveils XC30 Supercomputer 67

Nerval's Lobster writes "Cray has unveiled a XC30 supercomputer capable of high-performance computing workloads of more than 100 petaflops. Originally code-named 'Cascade,' the system relies on Intel Xeon processors and Aries interconnect chipset technology, paired with Cray's integrated software environment. Cray touts the XC30's ability to utilize a wide variety of processor types; future versions of the platform will apparently feature Intel Xeon Phi and Nvidia Tesla GPUs based on the Kepler GPU computing architecture. Cray leveraged its work with DARPA's High Productivity Computing Systems program in order to design and build the XC30. Cray's XC30 isn't the only supercomputer aiming for that 100-petaflop crown. China's Guangzhou Supercomputing Center recently announced the development of a Tianhe-2 supercomputer theoretically capable of 100 petaflops, but that system isn't due to launch until 2015. Cray also faces significant competition in the realm of super-computer makers: it only built 5.4 percent of the systems on the Top500 list, compared to IBM with 42.6 percent and Hewlett-Packard with 27.6 percent."

AMD Closes OSRC, Lays Off Several Linux Kernel Developers 94

From the H reporting on LinuxCon Europe comes news that several Linux kernel developers have been laid off by AMD as part of its workforce reduction. From the article: "OSRC staff primarily worked to develop the Linux support for AMD's server processors, but they also wrote code and extensions for related desktop and notebook CPUs – for example, they looked after the code to support CPU frequency scaling for the PowerNow and Turbo Core technologies. While working on the kernel's IOMMU and KVM support, one of AMD's former employees contributed to the development of the "IOMMU groups" feature that was integrated into Linux 3.6; this feature provides the basis for a new Linux 3.6 technology that allows a host's PCIe devices to be passed through to virtual machines and can also be used with Intel CPUs." Looks like the group was doing interesting research on hypervisors, lockless data structures, and multi-core synchronization primitives among other things. The Open Source Radeon driver developers are not affected by this at least.

Cloud Computing Needs To Embrace the Linux Model, Says Rackspace CTO 42

Nerval's Lobster writes "Companies are rushing to lock customer data into their specific walled gardens, Rackspace CTO John Engates argued in an interview after a Cloud Expo keynote in Silicon Valley. That makes it more important than ever to ensure that the cloud undergirding all the various functions of daily life remains open. 'These companies have grown up in the era of enterprise software and they're addicted to enterprise software margins, magnitudes more profitable than what we make as a hosting company,' he said. 'Now you have software companies embracing cloud computing and taking the same enterprise-software playbook they've had for years and trying to run it in the cloud.' Ultimately, he added, cloud computing needs to adopt the Linux model. 'Linux opened it up and gave you vendor choice, with numerous vendors bringing their own strengths to the table.'"

HP Becomes a Platinum Member of the Linux Foundation 64

who_stole_my_kidneys writes in about how HP has gained a seat on the Linux Foundation's board of directors. "Snagging a first-class upgrade might empty out the contents of your wallet, but be glad you're not trying to buy your way to the Linux Foundation's top table. With a strategic investment of $500,000, Hewlett Packard has just become a platinum member of the body, alongside companies like Intel, Qualcomm and Samsung. In exchange for all that cash, HP gets a seat on the Foundation's board of directors and will have a say in how to advance the foundation's aims — and hopefully give Open webOS a gentle push, too."
