Description
–
FLR capability is advertized when flr_supported
bit in private device_capability register space is
set.
Specifies the scale used for the Slot Power Limit
Value. It is set by the Set_Slot_Power_Limit
Message. This field is not set for Root ports
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap
Specifies the upper limit on power supplied by
slot. It is set by the Set_Slot_Power_Limit
Message. This field is not set for Root ports.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap
–
Indicate device is conforming to the ECN, PCI
Express Base Specification, Revision 1.1., or
subsequent PCI Express Base Specification
revisions. Path= i_cfg_func.i_cfg_private
–
Endpoint L1 Acceptable Latency. These bits are
programmable through register space. The bits
should be 0 for Root ports.
Path= i_cfg_func.i_cfg_private
Endpoint L0s Acceptable Latency. These bits are
programmable through register space. The value
should be 0 for root ports.
Path= i_cfg_func.i_cfg_private
Extended Tag Field Support. This bit is
programmable through register space. This
capability is not currently supported.
Path= i_cfg_func.i_cfg_private
Max Payload Size Supported. These bits are
programmable from the register space and default
value is based on define in version.v file. Path=
i_cfg_func.i_cfg_private
