DEVMAP_SET_CTX_TIMEOUT(9F) Kernel Functions for Drivers

NAME

devmap_set_ctx_timeout - set the timeout value for the context
management callback

SYNOPSIS

#include <sys/ddi.h>
#include <sys/sunddi.h>


void devmap_set_ctx_timeout(devmap_cookie_t dhp, clock_t ticks);

INTERFACE LEVEL

illumos DDI specific (illumos DDI).

PARAMETERS

dhp
An opaque mapping handle that the system uses to describe
the mapping.


ticks
Number of clock ticks to wait between successive calls to
the context management callback function.

DESCRIPTION

The devmap_set_ctx_timeout() function specifies the time interval for
the system to wait between successive calls to the driver's context
management callback function, devmap_contextmgt(9E).


Device drivers typically call devmap_set_ctx_timeout() in the
devmap_map(9E) routine. If the drivers do not call
devmap_set_ctx_timeout() to set the timeout value, the default
timeout value of 0 will result in no delay between successive calls
to the driver's devmap_contextmgt(9E) callback function.

CONTEXT

The devmap_set_ctx_timeout() function can be called from user,
interrupt, or kernel context.
