A Second Batch of AMDGPU Changes Readied For Linux 4.8 Kernel

Filed under
Graphics/Benchmarks
Linux

Submitted earlier this month was the main AMDGPU and Radeon DRM updates for Linux 4.8's DRM-Next while on Friday a second round of feature updates were submitted.

This second serving of AMDGPU/Radeon updates isn't as prominent as the main pull request, but there's still some new/improved functionality to land in DRM-Next in time for the Linux 4.8 merge window that will open up at the end of July.

  • Google Developers Improve Mesa's Android EGL Support
  • Nouveau DRM Code Updated For Linux 4.8

    The Nouveau open-source NVIDIA DRM driver changes have been queued in DRM-Next for the Linux 4.8 kernel.

    Nouveau updates this time around include GK20A/GM20B Tegra K1/X1 voltage and clock improvements as well as initial support for GP100 and GP104 GPUs. The latter provides initial KMS support for the GeForce GTX 1000 series. While NVIDIA did release some Pascal firmware, it ended up being only for the GP100 and not the GP104 or GP106. Thus with Linux 4.8 there isn't any hardware-accelerated support for the consumer GeForce GTX 1060/1070/1080 cards on the open-source driver stack. For those cards it comes down to un-accelerated kernel mode-setting support until NVIDIA releases the rest of the Pascal firmware in the future.

  • Nvidia 367.35 Linux Graphics Driver Released with VDPAU Feature Set H Support

    Today, July 15, 2016, Nvidia published a new long-lived graphics driver for UNIX-like operating systems, including GNU/Linux, FreeBSD, and Solaris, Nvidia 367.35.

    The Nvidia 367.35 video driver comes as an upgrade to the previous update, Nvidia 367.27, announced exactly one month ago, which introduced support for Nvidia's recently released GeForce GTX 1080 and GTK 1070 graphics cards on Linux kernel-based operating systems.

  • NVIDIA 367.35 Released, Supports 8K H.265 Video Decoding

    NVIDIA Corp is out today with a rather notewrothy 367.xx series Linux driver update.

    The NVIDIA 367.35 driver that was released moments ago has GeForce GTX 1000 "Pascal" support improvements along with performance improvements and more. The possible performance win is improved buffer write speeds of the NVIDIA DRMKMS driver by using write-combined DRM dumb buffers.

More NVIDIA CUDA Benchmarks With Blender Cycles Engine

Filed under
Graphics/Benchmarks

For those interested in Blender Cycles performance on NVIDIA hardware with CUDA, these latest benchmarks have GeForce GTX 900/700/600 series data points. The GTX 1000 Pascal numbers were left out of this later testing since as yesterday's numbers show Blender or somewhere in the software stack are some performance issues... See yesterday's articles for that data.

  • NVIDIA Provides A Surprise For Pascal GPU Owners Wanting Open-Source

    After it took NVIDIA until earlier this year to release the signed firmware for the GeForce GTX 900 "Maxwell" GPUs, I expected -- and based upon what I heard -- that it could be months before seeing the firmware for GeForce GTX 1000 "Pascal" GPUs in order to enable hardware acceleration with these latest-generation GPUs. Thus it's a huge surprise today to see NVIDIA already making public their Pascal GP100 firmware images!

    Hitting this afternoon in linux-firmware Git are the GP100 firmware files! There are 15 binary-only firmware blobs now part of the linux-firmware tree needed for initializing GP100 hardware. The GP100 blobs are named (for providing some reference) bl, ucode_load, ucode_unload, fecs_bl, fecs_data, fecs_inst, fecs_sig, gpccs_bl, gpccs_data, gpccs_inst, gpccs_sig, sw_bundle_init, sw_ctx, sw_method_init, and sw_nonctx. The largest of these blobs are 20955 bytes.

  • Just About 20 Lines Of Code Got Open-Source 3D Running On NVIDIA Pascal For Mesa

    Just a few hours ago I was writing about NVIDIA making public the GP100 "Pascal" GPU firmware binaries needed for as a requirement for bringing up GeForce GTX 1000 series hardware acceleration on the open-source driver stack. Now the initial support has landed in Nouveau's NVC0 Gallium3D driver within Mesa for allowing 3D support.

    Ben Skeggs of Red Hat landed an initial support patch that has 16 lines of new code and five lines of deletions that bring this initial GP100 series GPU support. The support mostly comes down to just adding the "0x130" case and various other relatively simple changes to allow this code to work. The bring-up for Pascal in the Nouveau stack is much more complicated within the Nouveau DRM kernel driver than what was needed for the Gallium3D user-space code. The GP100 Pascal Nouveau kernel changes so far were outlined in Initial Open-Source GeForce GTX 1000 "Pascal" Nouveau Driver Support -- that work is starting to land in Linux 4.8.

  • Blender Cycles Render Engine Benchmarks With NVIDIA CUDA On Linux

    Here is a look at the performance of the Blender 3D modeling/creation software with its Cycles Engine when making use of NVIDIA's CUDA API for GPU acceleration. Tests for this initial comparison include NVIDIA GeForce GTX 1000 "Pascal" and GTX 900 "Maxwell" graphics cards.

Distro Development: Rescatux and Bodhi

  • Rescatux 0.40 beta 9 released
    Many code in the grub side and in the windows registry side has been rewritten so that these new features could be rewritten. As a consequence it will be easier to maintain Rescapp. Finally the chntpw based options which modify the Windows registry now perform a backup of the Windows registry files in the unlikely case you want to undo some of the changes that Rescapp performs. I guess that in the future there will be a feature to be able to restore such backups from Rescapp itself, but, let’s focus on releasing an stable release. It’s been a while since the last one. UEFI feedback is still welcome. Specially if the Debian installation disks work for you but not the Rescatux ones.
  • Bodhi 4.0.0 Updates and July Donation Totals
    Late last month I posted a first alpha look at Bodhi 4.0.0. Work since then has been coming along slowly due to a few unpredictable issues and my own work schedule outside of Bodhi being hectic over the summer. Bodhi 4.0.0 will be happening, but likely not with a stable release until September. I am traveling again this weekend, but am hoping to get out a full alpha release with 32bit and non-PAE discs next week.

Emma A LightWeight Database Management Tool For Linux

Today who does not interact with databases and if you're a programmer then the database management is your daily task. For database management, there is a very popular tool called, MySQL Workbench. It's a tool that ships with tonnes of functionalities. But not all of us as beginner programmers use all Workbench features. So here we also have a very lightweight database manager in Linux, Emma.
