ddi_fm_error(9S) Kernel & Driver Data Structures ddi_fm_error(9S)
NAME
ddi_fm_error - I/O error status structure
SYNOPSIS
#include <sys/ddifm.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
A ddi_fm_error_t structure contains common data necessary for I/O error
handling. A pointer to a ddi_fm_error_t structure is passed to error
handling callbacks where it can then be used in a call to pci_ere‐
port_post(). The same structure is also returned to callers of
ddi_fm_acc_err_get() and ddi_fm_dma_err_get().
STRUCTURE MEMBERS
int fme_version;
uint64_t fme_ena;
int fme_status;
int fme_flag;
ddi_acc_handle_t fme_acc_handle;
ddi_dma_handle_t fme_dma_handle;
The fme_version is the current version of ddi_fm_error_t. Valid values
for the version are: DDI_FME_VER0 and DDI_FME_VER1.
The fme_ena is the FMA event protocol Format 1 Error Numeric Associa‐
tion (ENA) for this error condition.
The fme_flag field is set to DDI_FM_ERR_EXPECTED if the error is the
result of a DDI_ACC_CAUTIOUS protected operation. In this case,
fme_acc_handle is valid and the driver should check for and report only
errors not associated with the DDI_ACC_CAUTIOUS protected access opera‐
tion. This field can also be set to DDI_FM_ERR_POKE or DDI_FM_ERR_PEEK
if the error is the result of a ddi_peek(9F) or ddi_poke(9F) operation.
The driver should handle these in a similar way to DDI_FM_ERR_EXPECTED.
Otherwise, ddi_flag is set to DDI_FM_ERR_UNEXPECTED and the driver must
perform the full range of error handling tasks.
The fme_status indicates current status of an error handler callback or
resource handle:
DDI_FM_OK No errors were detected.
DDI_FM_FATAL An error which is considered fatal to the opera‐
tional state of the system was detected.
DDI_FM_NONFATAL An error which is not considered fatal to the opera‐
tional state of the system was detected.
DDI_FM_UNKNOWN An error was detected, but the driver was unable to
determine the impact of the error on the operational
state of the system.
The fme_acc_handle is the valid access handle associated with the error
that can be returned from pci_ereport_post()
The fme_dma_handle is the valid DMA handle associated with the error
that can be returned from pci_ereport_post()
