  • AMD Renoir Temperature Monitoring To Come With Linux 5.8

    When it comes to the support for AMD Ryzen 4000 "Renoir" laptop support under Linux, as outlined in my testing so far this month the main caveat is needing Linux 5.6~5.7 for good graphics support but on the likes of Ubuntu 20.04 LTS with Linux 5.4 you will not have GPU acceleration. At least in the case of the Lenovo IdeaPad 5 I have been using to test, you also need Linux 5.7 Git for battery sensor support. Another item that in turn is coming with Linux 5.8 is CPU temperature reporting for the Renoir processors.

  • Intel DPTF Battery Support Published For Linux

    The patches posted on Friday for the DPTF battery support expose new DPTF dynamic tuning information regarding laptop/ultrabook battery capabilities. Exposed are the maximum platform power that can be supported by the given battery, the maximum sustained power for the battery, the high frequency impedance value from the battery fuel gauge, and battery discharge current capability. The information is exposed via sysfs to user-space and also notification support for changes to the Intel Dynamic Tuning Battery state.

  • Allwinner Preparing Their A100 SoC Support For The Upstream Linux Kernel

    Allwinner Tech has prepared their initial Linux kernel patches for bringing up the A100 SoC. The A100 SoC is one of their newest tablet-focused SoCs moving forward.

    The Allwinner A100 is based on the Cortex-A53 paired with PowerVR graphics. This low~mid-range SoC is decent and better than some past Allwinner SoCs but not as interesting as the also recently announced Allwinner A200 in a big.LITTLE design and with much more exciting features.

Allwinner Submits A100 Initial Support to Mainline Linux

  • Allwinner Submits A100 Initial Support to Mainline Linux

    You may also have already used boards based on Allwinner processors with mainline Linux support. But so far you had to thank linux-sunxi community for all the mainlining work they do, and AFAIK Allwinner was not involved.

    But today, I noticed Allwinner A100 initial support was submitted by Frank Lee with an AllwinnerTech dot com email address, and although the company was involved in some other patchsets, AFAIK it might be the first time they work on mainlining one of their processors.

Linux 5.8 Kernel: Qualcomm Adreno, MacBooks and AMD

  • Qualcomm Adreno 650 + 640 GPUs To Be Supported By Mainline Linux 5.8 Kernel

    The crew working on the MSM DRM driver from Freedreno / Google / Code Aurora (Qualcomm) have an interesting batch of changes for this open-source GPU driver for Qualcomm Adreno hardware come Linux 5.8. New hardware to be supported by this open-source MSM driver in Linux 5.8 include Qualcomm's Adreno 405, 640, and 650 series. The Adreno 405 is an old, low-end part from the 400 series and used by the Snapdragon 415/615/616/617 SoCs. The Adreno 405 support isn't particularly exciting but it's there for those interested along with the relevant MSM8x36 changes to the MDP5 code.

  • Linux 5.8 Picking Up A Quirk For Being Able To Reboot The 2009 MacBook Without Hangs

    With the upcoming Linux 5.8 cycle a quirk is being added to be able to reboot the 2009 era Apple MacBook without needing to boot with any special flags. Up to now the 2009 Apple MacBook (Macbook6,1) required a reboot=pci boot parameter added to the kernel otherwise when rebooting the system there would be a hang. This late 2009 MacBook (MC207LL/A) with Core 2 Duo CPU is very slow by today's standards and hopefully many of you still aren't using it in production, but should you be doing so and running new kernel releases, with Linux 5.8 the kernel can reboot without hanging or needing to manually add the flag.

  • AMD Energy Driver Queued Ahead Of Linux 5.8 For Core/Package Power Sensors

    Landing this weekend in hwmon-next ahead of the upcoming Linux 5.8 kernel cycle is the recently reported on "amd_energy" driver for supporting AMD Zen/Zen2 core and package energy sensors. This is the recently reported on work of a Google engineer allowing AMD Zen CPUs to expose power usage on Linux via the Runtime Average Power Limiting (RAPL) framework. The amd_energy driver is making it to the Linux 5.8 kernel by way of the hardware monitoring "hwmon" subsystem thanks to this Google open-source contribution.

Why Drupal is the Best CMS

Some CMS packages require a license, while free products may be unreliable. Drupal 8 is open-source software licensed under the GPL. It is distributed free of charge, with no restrictions on use. This means you can customize the functions as you see fit. Today, the sheer number of community-contributed modules is astonishing — over 43,000! The platform may be refined and adjusted following your needs. You will not be dependent on Drupal creators. Features may be added and removed with ease. The open-source nature also means that functionality is under constant scrutiny from the vast international community, so any bugs are detected and fixed in no time. Read more
