How to Check Disk Space on Linux from the Command Line

Friday 22nd of June 2018 11:44:40 PM
Quick question: How much space do you have left on your drives? A little or a lot? Follow up question: Do you know how to find out? If you happen to use a GUI desktop (e.g., GNOME, KDE, Mate, Pantheon, etc.), the task is probably pretty simple. But what if you’re looking at a headless server, with no GUI? Do you need to install tools for the task? The answer is a resounding no. All the necessary bits are already in place to help you find out exactly how much space remains on your drives

Kernel and Graphics: PDS, VKMS and Nouveau

  • PDS 0.98s release
    PDS 0.98s is released with the following changes 1. Fix compilation issue on raspberry pi. 2. Minor rework and optimization on balance code path. 3. Fix wrong nr_max_tries in migrate_pending_tasks. This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.
  • PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations
    Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes. The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.
  • The State Of The VKMS Driver, Preparations For vBlank & Page Flip Events
    One of the exciting additions to look forward to with the upcoming Linux 4.19 kernel cycle is the virtual "VKMS" kernel mode-setting driver. The driver is still a work-in-progress, but multiple developers are working on it.
  • NIR Continues To Be Prepped For OpenCL Support
    Longtime Nouveau contributor Karol Herbst who joined Red Hat several months ago has been working on Nouveau NIR support as stepping towards SPIR-V/compute support and this summer the work very much remains an active target.
  • Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance
    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001. DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc. The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site. Read more
