# SPDX-License-Identifier: GPL-2.0-only # # EISA configuration # config HAVE_EISA bool menuconfig EISA bool "EISA support" depends on HAVE_EISA ---help--- The Extended Industry Standard Architecture (EISA) bus was developed as an open alternative to the IBM MicroChannel bus. The EISA bus provided some of the features of the IBM MicroChannel bus while maintaining backward compatibility with cards made for the older ISA bus. The EISA bus saw limited use between 1988 and 1995 when it was made obsolete by the PCI bus. Say Y here if you are building a kernel for an EISA-based machine. Otherwise, say N. config EISA_VLB_PRIMING bool "Vesa Local Bus priming" depends on X86 && EISA default n ---help--- Activate this option if your system contains a Vesa Local Bus (VLB) card that identify itself as an EISA card (such as the Adaptec AHA-284x). When in doubt, say N. config EISA_PCI_EISA bool "Generic PCI/EISA bridge" depends on !PARISC && PCI && EISA default y ---help--- Activate this option if your system contains a PCI to EISA bridge. If your system have both PCI and EISA slots, you certainly need this option. When in doubt, say Y. # Using EISA_VIRTUAL_ROOT on something other than an Alpha or # an X86 may lead to crashes... config EISA_VIRTUAL_ROOT bool "EISA virtual root device" depends on EISA && (ALPHA || X86) default y ---help--- Activate this option if your system only have EISA bus (no PCI slots). The Alpha Jensen is an example of such a system. When in doubt, say Y. config EISA_NAMES bool "EISA device name database" depends on EISA default y ---help--- By default, the kernel contains a database of all known EISA device names to make the information in sysfs comprehensible to the user. This database increases size of the kernel image by about 40KB, but it gets freed after the system boots up, so it doesn't take up kernel memory. Anyway, if you are building an installation floppy or kernel for an embedded system where kernel image size really matters, you can disable this feature and you'll get device ID instead of names. When in doubt, say Y.
