BFM Procedures and Functions
August 2014 Altera Corporation IP Compiler for PCI Express User Guide
rc_mempoll Procedure
Use the rc_mempoll procedure to poll a given DWORD in a given BFM shared
memory location.
msi_poll Procedure
The msi_poll procedure tracks MSI completion from the endpoint.
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.
