In this mode the bridge looks - not like a PCI bridge, but like a PCI endpoint device. The driver hides - hardware details, exposing memory windows, scratchpads and doorbells of the - other side via a hardware independent KPI to the <a class="Xr">ntb(4)</a> - subsystem.</p> -<p class="Pp">The hardware provides 2 or 3 memory windows to the other system's - memory, 16 scratchpad registers and 14, 31 or 34 doorbells to interrupt the - other system, depending on the platform. On Xeon processors one of the - memory windows is typically consumed by the driver itself to work around - multiple hardware errata.</p> -</section> -<section class="Sh"> -<h1 class="Sh" id="CONFIGURATION"><a class="permalink" href="#CONFIGURATION">CONFIGURATION</a></h1> -<p class="Pp">The NTB configuration should be set by BIOS. It includes enabling - NTB, choosing between NTB-to-NTB (back-to-back) or NTB-to-Root Port mode, - enabling split BAR mode (one of two 64-bit BARs can be split into two 32-bit - ones) and configuring BAR sizes in bits (from 12 to 29/39) for both NTB - sides.</p> -<p class="Pp">The recommended configuration is NTB-to-NTB mode, split bar - enabled and all BAR sizes set to 20 (1 MiB). This needs to be done on both - systems.
