Synopsis

#include <sys/ndifma.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

Solaris DDI specific (Solaris 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.
