Onboard 8051 processor and RAMROM memory If the BCM44xx or BCM57xx driver is loaded, attach procnetnicinfo. How to get information about graphics card GPU on Linux. Graphics processing units GPUYou need to find out the correct model and vendor of the graphics card on your system, to be able to install the appropriate drivers and get the hardware to function properly. Most modern linux distros can detect variety of graphics card, but do not always have the best driver for it. So if you have an external graphics card like Nvidia or Ati, then you need to find the model namenumber and then lookup further details online. Summary of the changes and new features merged in the Linux kernel during the 4. History The original NVM Express Work Group was incorporated as NVM Express, Inc. NVM Express. Www. Mellanox OFED for Linux User Manual Rev 1. Last Modified February, 2012. OpenBMC on different boards. Kernel. Upstream. HW. AST1250AST2400 SoC. MAC. SPI. UART. Watchdog. RTC. GPIO. USB. PWM. ADC.

But here we shall be using commands to find out the same information. Hardware details. The are only a few commands to learn. First one is lscpi and here is a quick example showing how to fetch details about graphics unit also called vga card or video card. VGA A 1. VGA compatible controller 0. Intel Corporation 8.

G3. 5 Express Integrated Graphics Controller 8. Note the numbers in the bracket 8. Such a number is present for almost all graphics card. The first part 8. Intel here and the second number 2. Now you can search google for more details using the Vendor name and the pci id. The lshw command can also be used to get the above information. C display. WARNING you should run this program as super user. VGA compatible controller. G3. 5 Express Integrated Graphics Controller 8. Intel Corporation 8.

Here is a sample output from a system having an nvidia geforce 2. VGA A 1. 2. 0. 1 0. VGA compatible controller 0. NVIDIA Corporation GT2. Ge. Force 2. 10 1. VGA controller. Integrated chipsets vs dedicated gpus. For dedicated units like nvidia or ati, you can easily search online for the model number or pci id. The specifications and other details would be available on the vendors website. However for integrated graphics chipsets like Intel GMA, you may not get sufficient details by just searching the series name 8. G3. 5 over here or pci id. The series covers many similar models, while the pci id might not be documented on the website. In that case, lookup the motherboard model and find its specifications. Vendors publish product specification documents for every motherboard model they manufacture. These contain technical details about the hardware. To find your motherboard model, use dmidecode or inxi command. Dmidecode sudo dmidecode t baseboard grep i Product. Product Name DG3. ECInxi inxi M. Machine Mobo Intel model DG3. EC version AAE2. Bios Intel version ECG3. M. 8. 6A. 0. 11. 2. The above output shows that its a Intel DG3. EC motherboard. Google up for that model to find the product specifiation document, and look for VideoGraphics information in it. Check hardware acceleration. With hardware based 3d acceleration, applications that need to draw 3d graphics can use the hardware directly to process and generate the graphics, speeding up 3d rendering significantly. For this, the graphics card must support hardware acceleration and the correct drivers must be installed on the system to use this feature. The 3d processing functions provided by the hardware adhere to the Open. GL specifications, and with the right hardware, applications can access them through the opengl api. Open. GL just defines the functions and the implementation is done inside the hardware which makes it very fast. However there are libraries like MESA that implement the opengl functions entirely inside software. So it is possible to render graphics using opengl without actually having an opengl compatible gpu. So by checking the opengl rendering library, we can find out if hardware acceleration is present or not. Check the glxinfo command output for Open. GL details glxinfo grep Open. GL. Open. GL vendor string Intel Open Source Technology Center. Open. GL renderer string Mesa DRI IntelR 9. G. Open. GL version string 2. Mesa 1. 0. 1. 0. Open. GL shading language version string 1. Open. GL extensions The Open. GL renderer string points to MESA libraries which means that 3d rendering is being handled entirely inside software. This is going to be slow and games would not work well. The output on a machine with dedicated nvidia geforce 2. Open. GL. Open. GL vendor string NVIDIA Corporation. Open. GL renderer string Ge. Force 2. 10PCIeSSE2. Open. GL core profile version string 3.

Note the line. Open. GL renderer string Ge. Force 2. 10PCIeSSE2. So the Open. GL renderer is Ge. Force, which is the nvidia proprietory driver. This indicates the hardware based 3d acceleration is available. So graphics performance would be good. Last Updated On 2.
