DDI_FM_EREPORT_POST(9F)DDI_FM_EREPORT_POST(9F)NAMEddi_fm_ereport_post - post an FMA Protocol Error Report Event
SYNOPSIS
#include <sys/ddifm.h>
void ddi_fm_ereport_post(dev_info_t *dip, char *ereport_class,
uint64_t ena, int *sflag, ... /* name-value pair args */);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
dip
Pointer to the dev_info structure
ereport_class
FMA Event Protocol error class
ena
Error Numeric Association
sflag
Determines whether caller can sleep for memory or
other event resources.
DESCRIPTION
The ddi_fm_ereport_post() function causes an encoded fault management
error report name-value pair list to be queued for delivery to the
Fault Manager daemon, fmd(1M). The sflag parameter indicates whether or
not the caller is willing to wait for system memory and event channel
resources to become available.
The following ereport_class strings are available for use by any leaf
device driver:
device.inval_state
A leaf driver discovers that the device is in
an invalid or inconsistent state. For example,
the driver might detect that receive or send
ring descriptor indices are corrupted. It might
also find an invalid value in a register or a
driver-to-device protocol violation.
device.no_response
A leaf driver times out waiting for a response
from the device. For example, timeouts can
occur when no confirmation is seen after reset‐
ting, enabling, or disabling part of the
device.
device.badint_limit
A leaf device sends too many consecutive inter‐
rupts with no work to do.
device.intern_corr
A leaf device reports to the driver that it has
itself detected an internal correctable error.
device.intern_uncorr
A leaf device reports to the driver that it has
itself detected an internal uncorrectable
error.
device.stall
A leaf driver determines that data transmission
has stalled indefinitely.
The ena indicates the Format 1 Error Numeric Association for this error
report. It might have already been initialized by another error-detect‐
ing software module. For example, if ddi_fm_ereport_post() is called
from an error handler callback function, the fme_ena field from the
passed-in ddi_fm_error argument should be used. Otherwise it should be
set to 0 and will be initialized by ddi_fm_ereport_post().
The name-value pair args variable argument list contains one or more
(names, type, value pointer) nvpair tuples for non-array data_type_t
types or one or more (name, type, number of elements, value pointer)
tuples for data_type_t array types. There is one mandatory tuple to
describe the ereport version. This should contain the following values:
o name - FM_VERSION
o type - DATA_TYPE_UINT8
o value - FM_EREPORT_VERS0
Additional nvpair tuples can describe error conditions for logging pur‐
poses, but are not interpreted by the I/O framework or fault manager.
The end of the argument list is specified by NULL.
CONTEXT
The ddi_fm_ereport_post() function can be called from user, kernel, or
high-level interrupt context.
