ddi-forceattach(9P)					   Kernel Properties for Drivers				       ddi-forceattach(9P)

NAME
ddi-forceattach, ddi-no-autodetach - properties controlling driver attach/detach behavior DESCRIPTION
Solaris device drivers are attached by devfsadm(1M) and by the kernel in response to open(2) requests from applications. Drivers not cur- rently in use can be detached when the system experiences memory pressure. The ddi-forceattach and ddi-no-autodetach properties can be used to customize driver attach/detach behavior. The ddi-forceattach is an integer property, to be set globally by means of the driver.conf(4) file. Drivers with this property set to 1 are loaded and attached to all possible instances during system startup. The driver will not be auto-detached due to system memory pressure. The ddi-no-autodetach is an integer property to be set globally by means of the driver.conf(4) file or created dynamically by the driver on a per-instance basis with ddi_prop_update_int(9F). When this property is set to 1, the kernel will not auto-detach driver due to system memory pressure. Note that ddi-forceattach implies ddi-no-autodetach. Setting either property to a non-integer value or an integer value not equal to 1 pro- duces undefined results. These properties do not prevent driver detaching in response to reconfiguration requests, such as executing com- mands cfgadm(1M), modunload(1M), rem_drv(1M), and update_drv(1M). SEE ALSO

NAME
ddi_binding_name, ddi_get_name - return driver binding name SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> char *ddi_binding_name(dev_info_t *dip); char *ddi_get_name(dev_info_t *dip); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
dip A pointer to the device's dev_info structure. DESCRIPTION
ddi_binding_name() and ddi_get_name() return the driver binding name. This is the name used to select a driver for the device. This name is typically derived from the device name property or the device compatible property. The name returned may be a driver alias or the driver name. RETURN VALUES
ddi_binding_name() and ddi_get_name() return the name used to bind a driver to a device. CONTEXT
ddi_binding_name() and ddi_get_name() can be called from user, kernel, or interrupt context. SEE ALSO
ddi_node_name(9F) Writing Device Drivers WARNINGS
The name returned by ddi_binding_name() and ddi_get_name() is read-only. SunOS 5.10 3 May 1996 ddi_binding_name(9F)
