Bar base address register
The system's firmware, device drivers or the operating system program the Base Address Registers (commonly called BARs) to inform the device of its address. PCI Configuration Base Address Registers. The PCI configuration space consists of up to six bit base address registers for each device. These registers.
When the system is powered up, the host must determine the memory size that the PCI agent requires and assign it a starting address.
Pci base address register programming
The lowest four bits are for Prefetch, Type, and Type Indicator. The middle 20 bits are hardwired to 0, for reasons explained below. This signals to bar base address register host that only https://bitcoin-money-wallet.site/address/binance-to-coinbase-address-verification-failed.html top 8 bits are writable.
The host will then allocate 16 MB of memory space, and write the BAR, this time giving it a valid address e.

This tells the agent that its 16 MB of memory space begins bar base address register the address AA According to the PCI specification, all address spaces must be naturally aligned, so it is not possible to https://bitcoin-money-wallet.site/address/how-to-get-money-from-bitcoin-address.html a bar base address register MB address space begin at a memory address bablu bar base address register by 16 MB.
This is why the middle 20 bits would be hardwired to 0. The host must know what the size is, and the agent would not need those bits to store an address.PCI and PCIe configuration space
For a memory BAR, the smallest possible size would leave  writable, which would be 16 bytes. By bar base address register same token, the largest size this web page only have 31 writable bits, which corresponds to a 2 GB size.
