.
msi_poll Procedure
The
msi_poll
procedure tracks MSI completion from the Endpoint.
Location altpcietb_bfm_driver_rp.v
Syntax msi_poll(max_number_of_msi,msi_address,msi_expected_dmawr,msi_expected_
dmard,dma_write,dma_read)
Arguments
max_number_of_msi Specifies the number of MSI interrupts to wait for.
msi_address The shared memory location to which the MSI messages will
be written.
msi_expected_dmawr When
dma_write
is set, this specifies the expected MSI data
value for the write DMA interrupts which is set by the
dma_
set_msi
procedure.
msi_expected_dmard When the
dma_read
is set, this specifies the expected MSI data
value for the read DMA interrupts which is set by the
dma_
set_msi
procedure.
Dma_write When set, poll for MSI from the DMA write module.
Dma_read When set, poll for MSI from the DMA read module.
dma_set_msi Procedure
The
dma_set_msi
procedure sets PCI Express native MSI for the DMA read or the DMA write.
Location altpcietb_bfm_driver_rp.v
