Installing Linux on the Asus GM501GS-XS74:

For starters,

If you are dual booting, install Windows first, and partition from there with a tool such as Minitool. You'll only need two partitions, one for root and optionally, a small one for swap (say, 8GB). Partition them as appropriate, and when done, reboot into the UEFI menu and ensure that:

(a). Secure boot is disabled (otherwise you won't be able to load up proprietary drivers needed for the Nvidia GPU).

(b). Confirm that you're booting in UEFI mode ONLY. This is the default. CSM should remain disabled. Here's why.

silly gist hack, why do we need you? :(

To limit a CPU to a certain C-state, you can pass the processor.max_cstate=X option in the kernel line of /boot/grub/grub.conf.

Here we limit the system to only C-State 1:

    kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1

On some systems, the kernel can override the BIOS setting, and the parameter intel_idle.max_cstate=0 may be required to ensure sleep states are not entered:

Build FFmpeg with Intel's QSV enablement on an Intel-based validation test-bed:

Build platform: Ubuntu 18.04LTS

Ensure the platform is up to date:

sudo apt update && sudo apt -y upgrade && sudo apt -y dist-upgrade

Install baseline dependencies first (inclusive of OpenCL headers+)

Brainiarc7

# first get the PPA repository driver
sudo add-apt-repository ppa:graphics-drivers/ppa

# install nvidai driver 
sudo apt install nvidia-384 nvidia-384-dev

# install other import packages
sudo apt-get install g++ freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libglu1-mesa libglu1-mesa-dev

# CUDA 9 requires gcc 6

Preparing Ubuntu 18.04LTS as an OpenCL development platform:

With OpenCL, the installable client drivers (ICDs) are normally issued with the accelerator's device drivers, namely:

1. The NVIDIA CUDA toolkit (and the device driver) for NVIDIA GPUs.
2. AMD's RoCM for GCN-class AMD hardware.
3. Intel's beignet and the newer Neo compute runtime.

The purpose of the installable client driver model is to allow multiple OpenCL platforms to coexist on the same platform. That way, multiple OpenCL accelerators, be they discrete GPUs paired with a combination of FPGAs and integrated GPUs can all coexist.

Intel OpenCL stack enablement on Ubuntu 18.04LTS.

Here's how to build and install Intel's new OpenCL enablement stack, Neo, which replaces the legacy Beignet ICD.

Install the dependencies:

Build dependencies:

sudo apt-get install ccache flex bison clang-4.0 cmake g++ git patch zlib1g-dev autoconf xutils-dev libtool pkg-config libpciaccess-dev
