BAR1ADDRWIDTH
Integer Specifies BAR 1 address width. Valid settings are:
0: 32 bits wide
1: 64 bits wide
When 64-bit addressing is selected, the BAR
occupies both the BAR1 and BAR2 registers.
BAR2ADDRWIDTH
Integer Specifies BAR 2 address width. Valid settings are:
0: 32 bits wide
1: 64 bits wide
When 64-bit addressing is selected, the BAR
occupies both the BAR2 and BAR3 registers.
BAR3ADDRWIDTH
Integer Specifies BAR 3 address width. Valid settings are:
0: 32 bits wide
1: 64 bits wide
When 64-bit addressing is selected, the BAR
occupies both the BAR3 and BAR4 registers.
BAR4ADDRWIDTH
Integer Specifies BAR 4 address width. Valid settings are:
0: 32 bits wide
1: 64 bits wide
When 64-bit addressing is selected, the BAR
occupies both the BAR4 and BAR5 registers.
Because BAR5 must always be 32-bits wide, there is
no BAR5ADDRWIDTH attribute.
BAR0PREFETCHABLE
Boolean Specifies BAR 0 memory region is prefetchable.
Valid settings are:
TRUE: prefetchable
FALSE: not prefetchable
BAR1PREFETCHABLE
Boolean Specifies BAR 1 memory region is prefetchable.
Valid settings are:
TRUE: prefetchable
FALSE: not prefetchable
BAR2PREFETCHABLE
Boolean Specifies BAR 2 memory region is prefetchable.
Valid settings are:
TRUE: prefetchable
FALSE: not prefetchable
BAR3PREFETCHABLE
Boolean Specifies BAR 3 memory region is prefetchable.
Valid settings are:
TRUE: prefetchable
FALSE: not prefetchable
BAR4PREFETCHABLE
Boolean Specifies BAR 4 memory region is prefetchable.
Valid settings are:
TRUE: prefetchable
FALSE: not prefetchable
