DDI_FM_ACC_ERR_CLEAR(9F) Kernel Functions for Drivers DDI_FM_ACC_ERR_CLEAR(9F)

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

#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);

illumos DDI specific (illumos DDI)

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.

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.
