6.14.1. VIRTIO PCI Configuration Access Request Interface

Table 77.  VIRTIO PCI* Cofiguatio Access Request Iteface = 0 o 1, p0 = pot 0, ad p1 = pot 1
Note: Pot 1 is oly available i D-Seies FPGAs
EP = Edpoit, RP = Root Pot, BP = TLP Bypass
Sigal Name Diectio Pot Mode Clock Domai Desciptio
p<>_ss_app_vitio_pcicfgeq_tvalid Output EP p<>_axi_lite_clk

Whe asseted, idicates a VIRTIO PCI* Cofiguatio Access Request has bee eceived fom the Host. The sigal is valid fo oe clock cycle.

p<>_ss_app_vitio_pcicfgeq_tdata[95:0] Output EP p<>_axi_lite_clk
  • Bit[0]: Whe set, the equest is a wite equest. O else, the equest is a ead equest.
  • Bit[1]: Idicates equest is fo the Vitual Fuctio implemeted i slot's physical fuctio.
  • Bit[12:2]: Idicates child VF umbe of paet PF idicated by PF umbe.
  • Bit[15:13]: The PF umbe of the equest (PF[2:0]).
  • Bit[20:16]: Reseved.
  • Bit[28:21]: The BAR value to be used fo the equest.
  • Bit[60:29]: The BAR offset value to be used fo the equest.
  • Bit [63:61]: The legth value to be used fo the equest.
  • Bit[95:64]: The data value to be used fo the wite equest. N/A fo ead equest.
