GLXSB(4) i386 Kernel Interfaces Manual GLXSB(4) NAME glxsb -- Geode LX Security Block crypto accelerator SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device crypto device glxsb Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): glxsb_load="YES" DESCRIPTION The glxsb driver supports the security block of the Geode LX series processors. The Geode LX is a member of the AMD Geode family of inte- grated x86 system chips. Driven by periodic checks for available data from the generator, glxsb supplies entropy to the random(4) driver for common usage. glxsb also supports acceleration of AES-128-CBC operations for crypto(4). It also registers itself to accelerate other HMAC algo- rithms, although there is no hardware acceleration for those algo- rithms. This is only needed so glxsb can work with ipsec(4). CAVEAT The crypto(9) framework will fail to open the crypto session on the de- vice if the AES key's length is != 128 bits. This prevents the use of the glxsb device driver with AES keys of length != 128 bits. SEE ALSO crypto(4), intro(4), ipsec(4), pci(4), random(4), crypto(7), crypto(9) HISTORY The glxsb device driver first appeared in OpenBSD 4.1. The glxsb de- vice driver was imported into FreeBSD 7.1. AUTHORS The glxsb device driver was written for OpenBSD by Tom Cosgrove. It was ported to FreeBSD by Patrick Lamaiziere <patfbsd@davenulle.org>. FreeBSD 14.3 July 29, 2020 GLXSB(4)
