Tool for extracting compression ratio and amount of compressed memory from zram swap partitions.
zraminfo
This is a simple tool for displaying memory information including
compression ratio and percentage of compressed memory in Linux kernel
using zram. This tool works without zram, but in that case it displays
only basic memory statistics.
With LC_NUMERIC=en_GB.utf8 the output of ./zraminfo looks like this:

Instructions to Update the BIOS/UEFI for an HP Laptop on Linux
Instructions to Update the BIOS/UEFI for an HP Laptop on Linux
To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP.
On a Linux system, the ESP is typically mounted on /boot/efi or /efi. Whithin you should also find a EFI directory, e.g. /boot/efi/EFI or /efi/EFI. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. You can replace that with the mount point your system uses.
The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. These files typically come preinstalled in HP Windows PCs. If you have these files you could skip Install HP-specific files.
