Description

 

 

 

 

 

 

 

 

 

The set of PCI/v3.0 BAR-parameters of

 

 

 

 

N = 0 to C_PCIBAR_NUM-1 are

 

 

 

 

meaningful and the parameters of N =

G26

C_PCIBAR_NUM

G27-G32

 

C_PCIBAR_NUM up to and including 2

 

have no effect. If C_PCIBAR_NUM = 3,

 

 

 

 

 

 

 

 

the set of PCI/v3.0 BAR-parameters of N

 

 

 

 

= 0 to 2 are all meaningful (i.e., G27-G32

 

 

 

 

are meaningful)

 

 

 

 

 

G27

C_PCIBAR2IPIFBAR_0

Only the high-order bits above the length

 

defined by G28 are meaningful

G30

Only the high-order bits above the length

defined by G30 are meaningful. Not

 

 

 

 

meaningful if G26=1-2
