Bus options (PCI, PCMCIA, EISA, GSC, ISA)Edit

Option: GSC
- Kernel Versions: 2.6.15.6 ...
- (on/off) VSC/GSC/HSC bus support
- default y
  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".

Option: HPPB
- Kernel Versions: 2.6.15.6 ...
- (on/off) HP-PB bus support
- depends on GSC
  The HP-PB bus was used in the Nova class and K-class servers. If in doubt, say "Y"

Option: IOMMU_CCIO
- Kernel Versions: 2.6.15.6 ...
- (on/off) U2/Uturn I/O MMU
- depends on GSC
  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.

Option: GSC_LASI
- Kernel Versions: 2.6.15.6 ...
- (on/off) Lasi I/O support
- depends on GSC
  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.

Option: GSC_WAX
- Kernel Versions: 2.6.15.6 ...
- (on/off) Wax I/O support
- depends on GSC
  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.

Option: EISA
- Kernel Versions: 2.6.15.6 ...
- (on/off) EISA support
- depends on GSC
  Say Y here if you have an EISA bus in your machine. This code supports both the Mongoose & Wax EISA adapters. It is sadly incomplete and lacks support for card-to-host DMA.

Option: ISA
- Kernel Versions: 2.6.15.6 ...
- (on/off) ISA support
- depends on EISA
  If you want to plug an ISA card into your EISA bus, say Y here. Most people should say N.

Option: PCI
- Kernel Versions: 2.6.15.6 ...
- (on/off) PCI support
  All recent HP machines have PCI slots, and you should say Y here if you have a recent machine. If you are convinced you do not have PCI slots in your machine (eg a 712), then you may say "N" here. Beware that some GSC cards have a Dino onboard and PCI inside them, so it may be safest to say "Y" anyway.

Option: GSC_DINO
- Kernel Versions: 2.6.15.6 ...
- (on/off) GSCtoPCI/Dino PCI support
- depends on PCI && GSC
  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.

Option: PCI_LBA
- Kernel Versions: 2.6.15.6 ...
- (on/off) LBA/Elroy PCI support
- depends on PCI
  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.

Option: IOSAPIC
- Kernel Versions: 2.6.15.6 ...
- (on/off)
- depends on PCI_LBA
- default PCI_LBA

Option: IOMMU_SBA
- Kernel Versions: 2.6.15.6 ...
- (on/off)
- depends on PCI_LBA
- default PCI_LBA

config PCI_EPIC

bool EPIC/SAGA PCI support

depends on PCI

default y

help

Say Y here for V-class PCI, DMA/IOMMU, IRQ subsystem support.

Option: SUPERIO
- Kernel Versions: 2.6.15.6 ...
- (on/off) SuperIO (SuckyIO) support
- depends on PCI_LBA
- default y
  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.

Option: CHASSIS_LCD_LED
- Kernel Versions: 2.6.15.6 ...
- (on/off) Chassis LCD and LED support
- default y
  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.

Option: PDC_CHASSIS
- Kernel Versions: 2.6.15.6 ...
- (on/off) PDC chassis State Panel support
- default y
  Say Y here if you want to enable support for the 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 has nothing to do with Chassis LCD and LED support. If unsure, say Y.

Option: PDC_STABLE
- Kernel Versions: 2.6.15.6 ...
- (on/off/module) PDC Stable Storage support
- depends on SYSFS
- default y
  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.
