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# Returns the function number for this device. 98# 99METHOD int get_function { 100 device_t dev; 101 device_t child; 102 int *func; 103} 104 105# 106# Activates (and powers up if necessary) the card's nth function 107# since each function gets its own device, there is no need to 108# to specify a function number 109# 110METHOD int activate_function { 111 device_t dev; 112 device_t child; 113} 114 115METHOD int deactivate_function { 116 device_t dev; 117 device_t child; 118} 119 120# 121# Compatibility methods for OLDCARD drivers. We use these routines to make 122# it possible to call the OLDCARD driver's probe routine in the context that 123# it expects. For OLDCARD these are implemented as pass throughs to the 124# device_{probe,attach} routines. For NEWCARD they are implemented such 125# such that probe becomes strictly a matching routine and attach does both 126# the old probe and old attach. 127# 128# compat devices should use the following: 129# 130# /* Device interface */ 131# DEVMETHOD(device_probe), pccard_compat_probe), 132# DEVMETHOD(device_attach), pccard_compat_attach), 133# /* Card interface */ 134# DEVMETHOD(card_compat_match, foo_match), /* newly written */ 135# DEVMETHOD(card_compat_probe, foo_probe), /* old probe */ 136# DEVMETHOD(card_compat_attach, foo_attach), /* old attach */ 137# 138# This will allow a single driver binary image to be used for both 139# OLDCARD and NEWCARD. 140# 141# Drivers wishing to not retain OLDCARD compatibility needn't do this. 142# 143# The compat_do_* versions are so that we can make the pccard_compat_probe 144# and _attach static lines and have the bus system pick the right version 145# to use so we don't enshrine pccard_* symbols in the driver's module. 146# 147METHOD int compat_probe { 148 device_t dev; 149} 150 151METHOD int compat_attach { 152 device_t dev; 153} 154 155CODE { 156 static int null_do_probe(device_t bus, device_t dev) 157 { 158 return (CARD_COMPAT_DO_PROBE(device_get_parent(bus), dev)); 159 } 160 161 static int null_do_attach(device_t bus, device_t dev) 162 { 163 return (CARD_COMPAT_DO_ATTACH(device_get_parent(bus), dev)); 164 } 165} 166 167METHOD int compat_do_probe { 168 device_t bus; 169 device_t dev; 170} DEFAULT null_do_probe; 171 172METHOD int compat_do_attach { 173 device_t bus; 174 device_t dev; 175} DEFAULT null_do_attach; 176 177# 178# Find "dev" in the passed table of devices.
