6.12. VF Error Flag Interface (vf_err/sent_vfnonfatalmsg)
When SRIOV is enabled, the PCIe* 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).
This interface exists when SRIOV is enabled only. N/A to PCIe* device type is Root Port.
Signal Name | Direction | Clock Domain | Description |
---|---|---|---|
ss_app_vf_err_poisonedwrreq_<w> | Output | axi_lite_clk | Indicates a Poisoned Write Request is received. |
ss_app_vf_err_poisonedcompl_<w> | Output | axi_lite_clk | Indicates a Poisoned Completion is received. |
ss_app_vf_err_ur_postedreq_<w> | Output | axi_lite_clk | Indicates the IP core received a Posted UR request. |
ss_app_vf_err_ca_postedreq_<w> | Output | axi_lite_clk | Indicates the IP core received a Posted CA request. |
ss_app_vf_err_vf_num[10:0]_<w> | Output | axi_lite_clk | Indicates the VF number for which the error is detected. |
ss_app_vf_err_func_num[2:0]_<w> | Output | axi_lite_clk | Indicates the physical function number associated with the VF that has the error. |
/ss_app_vf_err_overflow | Output | axi_lite_clk | Indicates a VF error FIFO overflow and a loss of an error report. The overflow can happen when axi_lite_clk is slower than the coreclkout_hip clock. It can also overflow internally in the HIP. |
app_ss_sent_vfnonfatalmsg | Input | axi_lite_clk | Indicates the user application sent a non-fatal error message in response to an error detected. |
app_ss_vfnonfatalmsg_vf_num[10:0] | Input | axi_lite_clk | Indicates the VF number for which the error message was generated. This bus is valid when app_ss_sent_vfnonfatalmsg is high. |
app_ss_vfnonfatalmsg_func_num[2:0] | Input | axi_lite_clk | Indicates the PF number associated with the VF with the error. This bus is valid when app_ss_sent_vfnonfatalmsg is high. |
