Synaptics SCSI & RAID Devices Driver Download

Posted By admin  On 08.04.21



This shall be a guide to configuring a Linux kernel for popular and modern x86_64 commodity hardware that is typically found in netbooks, laptops, desktops or off-the-shelf servers.I am not talking about embedded devices, development, big iron, other platforms, exotic hardware orperipherials. Just the standard stuff for running Linux. No discussion about modules vs. built-in. I dobuilt-in. The basis for this article is 5.7.0. Please always refer also to the help text of therespective kernel option. This article does not describe every possible config option becauseit omits whole categories that are not relevant on such systems. If you feel that there is a mistake and Ishould really recommend for or against a certain option or I got something upside down, please email me.I am not a kernel developer, even if I can find my way around in the code quite well.

I am using the following ackronyms in the comments:

Oct 14, 2015 Hi, I have a laptop HP EliteBook 8560p, and I am running a clean install of Windows 10 Professional 64bit on it. I just want to ask if you are planning to roll out the drivers for Windows 10 because the CPU usage is too high probably due to not updating of drivers. Synaptics delivers the absolute best-in-class wireless connectivity including state-of-the-art Wi-Fi 6, Bluetooth 5.x and L1+L5 dual frequency GPS.

  • DEV: useful for kernel development/debugging only, not for the general user
  • EMB: for embedded systems / development, does not apply to other systems, opposite of BIG. All those Arduino, Pi, Atom, Androids, Exynos, ARM and whatnot.
  • BIG: for big machines with hundreds of CPUs and TBs of RAM or HPC , opposite of EMB
  • STD: a standard feature that you can't easily live without, most people need or is generally good to have
  • REC: recommended feature to enable, a bit weaker than STD
  • OLD: modern systems don't need or shouldn't need it, opposite of STD
  • SEC: has security implications
  • AUTO: no need to enable this manually. It will get enabled automatically if needed.
  • COMPAT: recommended for backwards compatibility
  • VHOST: for running the kernel as a hypervisor/host for virtual machines
  • VGUEST: for running the kernel as a guest on a hypervisor
