User Guide
dma_set_header Procedure
Use the dma_set_header procedure to configure the DMA descriptor table for DMA
read or DMA write.
rc_mempoll Procedure
Use the rc_mempoll procedure to poll a given dword in a given BFM shared memory
location.
Arguments
bar_table Address of the Endpoint bar_table structure in BFM shared memory.
bar_num BAR number to analyze.
Table 17–59. dma_set_wr_desc_data_header Procedure
Table 17–60. dma_set_header Procedure
Location altpcietb_bfm_driver_rp.v
Syntax
dma_set_header (bar_table, bar_num, Descriptor_size, direction, Use_msi, Use_eplast,
Bdt_msb, Bdt_lab, Msi_number, Msi_traffic_class, Multi_message_enable)
Arguments
bar_table Address of the Endpoint bar_table structure in BFM shared memory.
bar_num BAR number to analyze.
Descriptor_size Number of descriptor.
direction
When 0 the direction is read.
When 1 the direction is write.
Use_msi
When set, the Root Port uses native PCI Express MSI to detect the DMA
completion.
Use_eplast
When set, the Root Port uses BFM shared memory polling to detect the
DMA completion.
Bdt_msb BFM shared memory upper address value.
Bdt_lsb BFM shared memory lower address value.
Msi_number
When use_msi is set, specifies the number of the MSI which is set by the
dma_set_msi procedure.
Msi_traffic_class
When use_msi is set, specifies the MSI traffic class which is set by the
dma_set_msi procedure.
Multi_message_enable
When use_msi is set, specifies the MSI traffic class which is set by the
dma_set_msi procedure.
Table 17–61. rc_mempoll Procedure
Location altpcietb_bfm_driver_rp.v
Syntax rc_mempoll (rc_addr, rc_data, rc_mask)
Arguments
rc_addr Address of the BFM shared memory that is being polled.
rc_data Expected data value of the that is being polled.
r c_mask
Mask that is logically AND ed with the shared memory data before it is
compared with rc_data .
