ddi_fm_init(9f)
ddi_fm_init(9F) Kernel Functions ddi_fm_init(9F)
NAME
ddi_fm_init, ddi_fm_fini, ddi_fm_capable - initialize and get the FM
capabilities for a device instance
SYNOPSIS
#include <sys/ddifm.h>
void ddi_fm_init(dev_info_t *dip, int *fm_capability,
ddi_iblock_cookie_t *ibcp);
void ddi_fm_fini(dev_info_t *dip);
int ddi_fm_capable(dev_info_t *dip, int *fm_capability);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
ddi_fm_init()
dip Pointer to the dev_info structure
fm_capability Fault Management capability bit mask
ibcp Pointer to where the interrupt block cookie should be
returned.
DESCRIPTION
A device driver can declare its fault management capabilities to the
I/O Fault Management framework by calling ddi_fm_init(). The
ddi_fm_init() function allocates and initializes resources according to
the bitwise-inclusive-OR of the fault management capabilities, de‐
scribed in the following and supported by the driver's immediate nexus
parent.
DDI_FM_NOT_CAPABLE The driver does not support any FMA features.
This is the default value assigned to device
drivers.
DDI_FM_EREPORT_CAPABLE The driver generates FMA protocol error
events (ereports) upon the detection of an
error condition.
DDI_FM_ACCCHK_CAPABLE The driver checks for errors upon the comple‐
tion of one or more access I/O transactions.
DDI_FM_DMACHK_CAPABLE The driver checks for errors upon the comple‐
tion of one or more DMA I/O transactions.
DDI_FM_ERRCB_CAPABLE The driver is capable of error handler call‐
back registration.
If the parent nexus is not capable of supporting any one of the re‐
quested capabilities, the associated bit will not be set and returned
as such to the driver. Before returning from ddi_fm_init(), the I/O
Fault Management framework creates a set of fault management capability
properties: fm-ereport-capable, fm-errcb-capable, fm-accchk-capable,
and fm-dmachk-capable. The current supported fault management capabil‐
ity levels are observable via prtconf(8).
A driver can support the administrative selection of fault management
capabilities by exporting and setting a fault management capability
level property in its driver.conf(5) file to the values described
above. The fm_capable properties must be set and read prior to calling
ddi_fm_init() with the desired capability list.
ddi_fm_fini() This function cleans up resources allocated to sup‐
port fault management for the dip structure.
ddi_fm_capable() This function returns the capability bit mask cur‐
rently set for the dip structure.
CONTEXT
These functions can be called from kernel context in a driver at‐
tach(9E) or detach(9E) operation.
