# SPDX-License-Identifier: GPL-2.0-only menu "Bus options (PCI, PCMCIA, EISA, GSC, ISA)" config GSC bool "VSC/GSC/HSC bus support" select HAVE_EISA default y help The VSC, GSC and HSC busses were used from the earliest 700-series workstations up to and including the C360/J2240 workstations. They were also used in servers from the E-class to the K-class. They are not found in B1000, C3000, J5000, A500, L1000, N4000 and upwards. If in doubt, say "Y". config HPPB bool "HP-PB bus support" depends on GSC help The HP-PB bus was used in the Nova class and K-class servers. If in doubt, say "Y" config IOMMU_CCIO bool "U2/Uturn I/O MMU" depends on GSC help Say Y here to enable DMA management routines for the first generation of PA-RISC cache-coherent machines. Programs the U2/Uturn chip in "Virtual Mode" and use the I/O MMU. config GSC_LASI bool "Lasi I/O support" depends on GSC help Say Y here to support the Lasi multifunction chip found in many PA-RISC workstations & servers. It includes interfaces for a parallel port, serial port, NCR 53c710 SCSI, Apricot Ethernet, Harmony audio, PS/2 keyboard & mouse, ISDN, telephony and floppy. Note that you must still enable all the individual drivers for these chips. config GSC_WAX bool "Wax I/O support" depends on GSC help Say Y here to support the Wax multifunction chip found in some older systems, including B/C/D/R class and 715/64, 715/80 and 715/100. Wax includes an EISA adapter, a serial port (not always used), a HIL interface chip and is also known to be used as the GSC bridge for an X.25 GSC card. config ISA bool "ISA support" depends on EISA help If you want to plug an ISA card into your EISA bus, say Y here. Most people should say N. config GSC_DINO bool "GSCtoPCI/Dino PCI support" depends on PCI && GSC help Say Y here to support the Dino & Cujo GSC to PCI bridges found in machines from the B132 to the C360, the J2240 and the A180. Some GSC/HSC cards (eg gigabit & dual 100 Mbit Ethernet) have a Dino on the card, and you also need to say Y here if you have such a card. Note that Dino also supplies one of the serial ports on certain machines. If in doubt, say Y. config PCI_LBA bool "LBA/Elroy PCI support" depends on PCI help Say Y here to support the Elroy PCI Lower Bus Adapter. This is present on B, C, J, L and N-class machines with 4-digit model numbers and the A400/A500. config IOSAPIC bool depends on PCI_LBA default PCI_LBA config IOMMU_SBA bool depends on PCI_LBA default PCI_LBA endmenu menu "PA-RISC specific drivers" config SUPERIO bool "SuperIO (SuckyIO) support" depends on PCI_LBA default y help Say Y here to support the SuperIO chip found in Bxxxx, C3xxx and J5xxx+ machines. This enables IDE, Floppy, Parallel Port, and Serial port on those machines. config CHASSIS_LCD_LED bool "Chassis LCD and LED support" default y select VM_EVENT_COUNTERS help Say Y here if you want to enable support for the Heartbeat, Disk/Network activities LEDs on some PA-RISC machines, or support for the LCD that can be found on recent material. This has nothing to do with LED State support for A and E class. If unsure, say Y. config PDC_CHASSIS bool "PDC chassis state codes support" default y help Say Y here if you want to enable support for Chassis codes. That includes support for LED State front panel as found on E class, and support for the GSP Virtual Front Panel (LED State and message logging) as found on high end servers such as A, L and N-class. This driver will also display progress messages on LCD display, such as "INI", "RUN" and "FLT", and might thus clobber messages shown by the LED/LCD driver. This driver updates the state panel (LED and/or LCD) upon system state change (eg: boot, shutdown or panic). If unsure, say Y. config PDC_CHASSIS_WARN bool "PDC chassis warnings support" depends on PROC_FS default y help Say Y here if you want to enable support for Chassis warnings. This will add a proc entry '/proc/chassis' giving some information about the overall health state of the system. This includes NVRAM battery level, overtemp or failures such as fans or power units. If unsure, say Y. config PDC_STABLE tristate "PDC Stable Storage support" depends on SYSFS default y help Say Y here if you want to enable support for accessing Stable Storage variables (PDC non volatile variables such as Primary Boot Path, Console Path, Autoboot, Autosearch, etc) through SysFS. If unsure, say Y. To compile this driver as a module, choose M here. The module will be called pdc_stable. endmenu
