DDI_FM_ACC_ERR_CLEAR(9F) Kernel Functions for Drivers

NAME

ddi_fm_acc_err_clear, ddi_fm_dma_err_clear - clear the error status
for an access or DMA handle

SYNOPSIS

#include <sys/ddifm.h>

void ddi_fm_acc_err_clear(ddi_acc_handle_t acc_handle,
int version);


void ddi_fm_dma_err_clear(ddi_dma_handle_t dma_handle,
int version);

INTERFACE LEVEL

illumos DDI specific (illumos DDI)

PARAMETERS

acc_handle
Data access handle obtained from a previous call to
ddi_regs_map_setup(9F), ddi_dma_mem_alloc(9F), or to a
similar function.


dma_handle
DMA handle obtained from a previous call to
ddi_dma_mem_alloc(9F) or one of its derivatives.


version
Version number of ddi_fm_error_t.

DESCRIPTION

The ddi_fm_dma_err_clear() and ddi_fm_acc_err_clear() functions clear
the error status of a DMA or access handle respectively.


Once cleared, the driver is again able to access the mapped registers
or memory using programmed I/O through the handle.
