7.11. VF Error Flag Interface
When SR-IOV is enabled, the GTS AXI Streaming IP provides a passage for the HIP's VF Error Flag Interface to application logic. In the absence of AER and Error Message Generation support for VF in the HIP, the generation of VF's Non-Fatal Error messages relies on the user application logic. It is up to the user application logic to generate appropriate PCIe* error messages when specific error conditions occur (as indicated by this interface).
Signal Name | Direction | Endpoint (EP)/Root Port (RP)/TLP Bypass (BP) | Clock Domain | Description |
---|---|---|---|---|
p<n>_ss_app_vf_err_poisonedwrreq_s0 | Output | EP | p<n>_axi_lite_clk | Indicates a Poisoned Write Request is received. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_poisonedcompl_s0 | Output | EP | p<n>_axi_lite_clk | Indicates a Poisoned Completion Request is received. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_ur_postedreq_s0 | Output | EP | p<n>_axi_lite_clk | Indicates a Posted UR Request is received. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_ca_postedreq_s0 | Output | EP | p<n>_axi_lite_clk | Indicates a Posted CA Request is received. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_vf_num_s0 [10:0] | Output | EP | p<n>_axi_lite_clk | Indicates the VF number for which the error is detected. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_func_num_s0[2:0] | Output | EP | p<n>_axi_lite_clk | Indicates the physical function number associated with the VF that has the error. x8 instance has s0 and s1. x4 instance has s0 only. |
p<n>_ss_app_vf_err_overflow | Output | EP | p<n>_axi_lite_clk | Indicates a VF error FIFO overflow and a loss of an error report. |
p<n>_app_ss_sent_vfnonfatalmsg | Input | EP | p<n>_axi_lite_clk | Indicates the user application sent a non-fatal error message in response to an error detected. |
p<n>_app_ss_vfnonfatalmsg_vf_num[10:0] | Input | EP | p<n>_axi_lite_clk | Indicates the VF number for which the error message was generated. This bus is valid when p<n>_app_ss_sent_vfnonfatalmsg is high. |
p<n>_app_ss_vfnonfatalmsg_func_num[2:0] | Input | EP | p<n>_axi_lite_clk | Indicates the PF number associated with the VF with the error. This bus is valid when p<n>_app_ss_sent_vfnonfatalmsg is high. |
p<n>_ss_app_vfnonfatalmsg_ready | Output | EP | p<n>_axi_lite_clk | Indicates that the interface can accept a transfer in the current cycle when asserted. |
