We need to set attributes for memory 40# and i/o port mappings (as well as other types of attributes) that have 41# a well defined meaning inside the pccard/cardbus system. The bus 42# methods are inadequate for this because this must be done at the time the 43# resources are set for the device, which predates their activation. Also, 44# the driver activating the resources doesn't necessarily know or need to know 45# these attributes. 46# 47METHOD int set_res_flags { 48 device_t dev; 49 device_t child; 50 int restype; 51 int rid; 52 u_long value; 53}; 54 55METHOD int get_res_flags { 56 device_t dev; 57 device_t child; 58 int restype; 59 int rid; 60 u_long *value; 61}; 62 63# 64# Sets the memory offset of the pccard bridge's window into attribute 65# or common memory space. 66# 67METHOD int set_memory_offset { 68 device_t dev; 69 device_t child; 70 int rid; 71 uint32_t cardaddr; 72 uint32_t *deltap; 73} 74 75METHOD int get_memory_offset { 76 device_t dev; 77 device_t child; 78 int rid; 79 uint32_t *offset; 80} 81 82# 83# pccard bridges call this method to initate the attachment of a card 84# 85METHOD int attach_card { 86 device_t dev; 87} 88 89# 90# pccard bridges call this to detach a card. 91# 92METHOD int detach_card { 93 device_t dev; 94} 95 96# 97# Activates (and powers up if necessary) the card's nth function 98# since each function gets its own device, there is no need to 99# to specify a function number 100# 101METHOD int activate_function { 102 device_t dev; 103 device_t child; 104} 105 106METHOD int deactivate_function { 107 device_t dev; 108 device_t child; 109} 110 111# 112# Compatibility methods for OLDCARD drivers. We use these routines to make 113# it possible to call the OLDCARD driver's probe routine in the context that 114# it expects. For OLDCARD these are implemented as pass throughs to the 115# device_{probe,attach} routines. For NEWCARD they are implemented such 116# such that probe becomes strictly a matching routine and attach does both 117# the old probe and old attach. 118# 119# compat devices should use the following: 120# 121# /* Device interface */ 122# DEVMETHOD(device_probe), pccard_compat_probe), 123# DEVMETHOD(device_attach), pccard_compat_attach), 124# /* Card interface */ 125# DEVMETHOD(card_compat_match, foo_match), /* newly written */ 126# DEVMETHOD(card_compat_probe, foo_probe), /* old probe */ 127# DEVMETHOD(card_compat_attach, foo_attach), /* old attach */ 128# 129# This will allow a single driver binary image to be used for both 130# OLDCARD and NEWCARD. 131# 132# Drivers wishing to not retain OLDCARD compatibility needn't do this. 133# 134# The compat_do_* versions are so that we can make the pccard_compat_probe 135# and _attach static lines and have the bus system pick the right version 136# to use so we don't enshrine pccard_* symbols in the driver's module. 137# 138METHOD int compat_probe { 139 device_t dev; 140} 141 142METHOD int compat_attach { 143 device_t dev; 144} 145 146CODE { 147 static int null_do_probe(device_t bus, device_t dev) 148 { 149 return (CARD_COMPAT_DO_PROBE(device_get_parent(bus), dev)); 150 } 151 152 static int null_do_attach(device_t bus, device_t dev) 153 { 154 return (CARD_COMPAT_DO_ATTACH(device_get_parent(bus), dev)); 155 } 156} 157 158METHOD int compat_do_probe { 159 device_t bus; 160 device_t dev; 161} DEFAULT null_do_probe; 162 163METHOD int compat_do_attach { 164 device_t bus; 165 device_t dev; 166} DEFAULT null_do_attach; 167 168# 169# Find "dev" in the passed table of devices.
