NAME

       ddi_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 chan-
       nel 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  regis-
			       ter 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 confirma-
			       tion is seen after resetting, enabling, or disabling part of the device.

       device.badint_limit     A leaf device sends too many consecutive interrupts 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-
       detecting  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 purposes, 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.
