Description
–
This is bit is read back a 1, whenever a non-
posted request initiated by PCIE core is pending
to be completed. Path= i_tl_top
This bit is the current state of the VAUX_PRSNT
pin of the device. When it is '1', it is indicating that
part needs VAUX and detects the VAUX is
present. Path= input to pcie_vaux_pipe
UnSupported Request Detected.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Fatal Error Detected.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Non-Fatal Error Detected.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Correctable Error Detected.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Initiate Function Level reset. This bit is writeable
only if flr_supported bit in private
device_capability register is set. A write of 1 to this
bit initiates Function Level Reset. The value read
by s/w from this bit is always 0.
Maximum Read Request Size. Depending on the
spec, internal logic uses either the min or the max
of the value of the two functions.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Enable No Snoop. When this bit is set to 1, PCIE
initiates a read request with the No Snoop bit in
the attribute field set for the transactions that
request the No Snoop attribute.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
This bit when set enables device to draw aux
power independent of PME AUX power
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
–
Extended Tag Field Enable. This capability is not
supported.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Max Payload Size. Depending on the spec,
internal logic uses either the min or the max of the
value of the two functions.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Relax Ordering Enable.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
Unsupported Request Reporting Enable.
Path= i_cfg_func.i_cfg_public.i_cfg_exp_cap.
