2 # RapidIO configuration
4 source "drivers/rapidio/devices/Kconfig"
6 config RAPIDIO_DISC_TIMEOUT
7 int "Discovery timeout duration (seconds)"
11 Amount of time a discovery node waits for a host to complete
12 enumeration before giving up.
14 config RAPIDIO_ENABLE_RX_TX_PORTS
15 bool "Enable RapidIO Input/Output Ports"
18 The RapidIO specification describes a Output port transmit
19 enable and a Input port receive enable. The recommended state
20 for Input ports and Output ports should be disabled. When
21 this switch is set the RapidIO subsystem will enable all
22 ports for Input/Output direction to allow other traffic
23 than Maintenance transfers.
25 config RAPIDIO_DMA_ENGINE
26 bool "DMA Engine support for RapidIO"
31 Say Y here if you want to use DMA Engine frameork for RapidIO data
32 transfers to/from target RIO devices. RapidIO uses NREAD and
33 NWRITE (NWRITE_R, SWRITE) requests to transfer data between local
34 memory and memory on remote target device. You need a DMA controller
35 capable to perform data transfers to/from RapidIO.
37 If you are unsure about this, say Y here.
40 bool "RapidIO subsystem debug messages"
43 Say Y here if you want the RapidIO subsystem to produce a bunch of
44 debug messages to the system log. Select this if you are having a
45 problem with the RapidIO subsystem and want to see more of what is
48 If you are unsure about this, say N here.
51 prompt "Enumeration method"
53 default RAPIDIO_ENUM_BASIC
55 There are different enumeration and discovery mechanisms offered
56 for RapidIO subsystem. You may select single built-in method or
57 or any number of methods to be built as modules.
58 Selecting a built-in method disables use of loadable methods.
60 If unsure, select Basic built-in.
62 config RAPIDIO_ENUM_BASIC
65 This option includes basic RapidIO fabric enumeration and discovery
66 mechanism similar to one described in RapidIO specification Annex 1.
71 tristate "RapidIO Channelized Messaging driver"
74 This option includes RapidIO channelized messaging driver which
75 provides socket-like interface to allow sharing of single RapidIO
76 messaging mailbox between multiple user-space applications.
77 See "Documentation/rapidio/rio_cm.txt" for driver description.
79 config RAPIDIO_MPORT_CDEV
80 tristate "RapidIO /dev mport device driver"
83 This option includes generic RapidIO mport device driver which
84 allows to user space applications to perform RapidIO-specific
85 operations through selected RapidIO mport.
