Linux 5.9 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes […]

Collabora & Microsoft to Bring OpenCL 1.2 and OpenGL 3.3 to DirectX 12 enabled Windows Devices

Collabora has been working on open-source graphics projects for a while, including Panfrost open-source drivers for Arm Midgard and Bitfrost GPUs which got experimental OpenGL ES 3.0 support earlier this year. But the company has also been working with Microsoft in order to provide an OpenCL 1.2 & OpenGL 3.3 translation layer for Windows devices compatible with DirectX 12. Their solution relies on Mesa 3D OpenCL and OpenGL open-source implementation with three main components: an OpenCL compiler using LLVM and the SPIRV-LLVM-Translator to generate SPIR-V representations of OpenCL kernels. The data goes through an SPIR-V to NIR translator (NIR is Mesa’s internal representation for GPU shaders), and finally to NIR-to-DXIL generating a DXIL compute shader and metadata understood by DirectX 12 (D3D12) a custom OpenCL runtime to do a direct translation of DirectX 12 (Not based on Mesa Clover implementation) a Gallium driver that builds and executes command-buffers on the […]

Microsoft Unveils The Vision AI Developer Kit For AI on the Edge

The field of Artificial Intelligence is getting more exciting every single day, and the big corporations and startups are massively pouring for it. One thing I am undoubtedly sure about is that the future will certainly be remarkable. Microsoft, the biggest software company in the world with sales over $100 billion has been venturing in the domain of artificial intelligence for a while now with cloud computing platform Azure and other related cloud computing services, but instead of its usual cloud computing route for AI, Microsoft is banking on AI on the edge with the introduction of the Vision AI Developer Kit in joint partnership with the semiconductor giant Qualcomm. With millions of data collected at the Edge, the potential of artificial intelligence on the edge is promising. AI cases performed on the Edge will help in making critical decisions, and more data insight can even facilitate important business scenarios. […]

Microsoft to Support exFAT File System in Linux, Releases exFAT Specification

Microsoft’s exFAT file system is quite popular for removable mass storage devices such as SD cards and USB flash drives as it’s supported in Windows, and many consumers devices such as cameras can handle Microsoft’s patented file system. The “patent” part causes an issue in Linux, as companies need to license it in order to ship it in their products or operating systems image. I recently re-installed Ubuntu 18.04 on my laptop, and if I reinsert my “test” USB drive: BTRFS, EXT-4, and NTFS partitions all mount automatically, but not the exFAT one. If I click on the partition, I get this message: That’s because Canonical does not provide exFAT by default in Ubuntu due to legal issues. It’s however easy enough for the user to install exFAT utilities

sudo apt install exfat-fuse exfat-utils

1	sudo apt install exfat-fuse exfat-utils

The drive will mount successfully:

 mount | grep -i exfat
/dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

1 2	mount \| grep -i exfat /dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

Note that it’s using FUSE (Filesystem in Userspace), and it’s usually not a problem […]

Windows Subsystem for Linux 2 Gets a Linux Kernel, Faster File System, Docker Support

Microsoft first introduced Windows Subsystem for Linux in 2016 in order to let developers runs bash command from Ubuntu user space without having to install Ubuntu in a virtual machine or container. It relies on the Windows kernel with a library converting Linux system calls into ones compatible with Windows. Performance is great until you start to involve file systems calls, for example during code compilations, something that’s fairly common for developers… Microsoft has been working on solving this performance issue, and compatibility issues with software such as Docker, and is now close to releasing Windows Subsystem for Linux 2 (WSL 2) featuring its own Linux 4.19 kernel instead of the Windows kernel plus a translation layer. WSL 2 uses virtualization technology to run its custom Linux kernel inside of a lightweight utility virtual machine (VM) which takes just 2 seconds to boot. That also means there will be separate […]
