8	default y
9	help
10	  The VSC, GSC and HSC busses were used from the earliest 700-series
11	  workstations up to and including the C360/J2240 workstations.  They
12	  were also used in servers from the E-class to the K-class.  They
13	  are not found in B1000, C3000, J5000, A500, L1000, N4000 and upwards.
14	  If in doubt, say "Y".

19	help
20	  The HP-PB bus was used in the Nova class and K-class servers.

24	bool "U2/Uturn I/O MMU"
25	depends on GSC
26	help
27	  Say Y here to enable DMA management routines for the first
28	  generation of PA-RISC cache-coherent machines.  Programs the
29	  U2/Uturn chip in "Virtual Mode" and use the I/O MMU.
30
31config GSC_LASI
32	bool "Lasi I/O support"
33	depends on GSC
34	help
35	  Say Y here to support the Lasi multifunction chip found in
36	  many PA-RISC workstations & servers.	It includes interfaces
37	  for a parallel port, serial port, NCR 53c710 SCSI, Apricot
38	  Ethernet, Harmony audio, PS/2 keyboard & mouse, ISDN, telephony
39	  and floppy.  Note that you must still enable all the individual
40	  drivers for these chips.

42config GSC_WAX
43	bool "Wax I/O support"
44	depends on GSC
45	help
46	  Say Y here to support the Wax multifunction chip found in some
47	  older systems, including B/C/D/R class and 715/64, 715/80 and
48	  715/100.  Wax includes an EISA adapter, a serial port (not always
49	  used), a HIL interface chip and is also known to be used as the
50	  GSC bridge for an X.25 GSC card.
51
52config ISA
53	bool "ISA support"
54	depends on EISA
55	help
56	  If you want to plug an ISA card into your EISA bus, say Y here.
57	  Most people should say N.

59config GSC_DINO
60	bool "GSCtoPCI/Dino PCI support"
61	depends on PCI && GSC
62	help
63	  Say Y here to support the Dino & Cujo GSC to PCI bridges found in
64	  machines from the B132 to the C360, the J2240 and the A180.  Some
65	  GSC/HSC cards (eg gigabit & dual 100 Mbit Ethernet) have a Dino on
66	  the card, and you also need to say Y here if you have such a card.
67	  Note that Dino also supplies one of the serial ports on certain
68	  machines.  If in doubt, say Y.

70config PCI_LBA
71	bool "LBA/Elroy PCI support"
72	depends on PCI
73	help
74	  Say Y here to support the Elroy PCI Lower Bus Adapter.  This is
75	  present on B, C, J, L and N-class machines with 4-digit model
76	  numbers and the A400/A500.

95	default y
96	help
97	  Say Y here to support the SuperIO chip found in Bxxxx, C3xxx and
98	  J5xxx+ machines. This enables IDE, Floppy, Parallel Port, and
99	  Serial port on those machines.

101config CHASSIS_LCD_LED
102	bool "Chassis LCD and LED support"
103	depends on LEDS_CLASS=y

105	select LEDS_TRIGGERS
106	help
107	  Say Y here if you want to enable support for the Heartbeat,
108	  Disk/Network activities LEDs on some PA-RISC machines,
109	  or support for the LCD that can be found on recent material.
110
111	  This has nothing to do with LED State support for A and E class.
112
113	  If unsure, say Y.
114
115config PDC_CHASSIS
116	bool "PDC chassis state codes support"
117	default y
118	help
119	  Say Y here if you want to enable support for Chassis codes.
120	  That includes support for LED State front panel as found on E
121	  class, and support for the GSP Virtual Front Panel (LED State and
122	  message logging)  as found on high end servers such as A, L and
123	  N-class.
124	  This driver will also display progress messages on LCD display,
125	  such as "INI", "RUN" and "FLT", and might thus clobber messages
126	  shown by the LED/LCD driver.
127	  This driver updates the state panel (LED and/or LCD) upon system
128	  state change (eg: boot, shutdown or panic).
129
130	  If unsure, say Y.

136	default y
137	help
138	  Say Y here if you want to enable support for Chassis warnings.
139	  This will add a proc entry '/proc/chassis' giving some information
140	  about the overall health state of the system.
141	  This includes NVRAM battery level, overtemp or failures such as
142	  fans or power units.
143
144	  If unsure, say Y.

153	  variables (PDC non volatile variables such as Primary Boot Path,
154	  Console Path, Autoboot, Autosearch, etc) through SysFS.
155
156	  If unsure, say Y.
157
158	  To compile this driver as a module, choose M here.
159	  The module will be called pdc_stable.
