This is v2 of a follow-up to the "Boot GSP with vGPU enabled" series [1]. It provides GSP-RM with the VF topology required for per-VF interrupt and doorbell event routing. When vGPU mode is enabled, GspSetSystemInfo reads the SR-IOV topology through the typed Rust PCI capability API and fills the embedded GSP_VF_INFO. When vGPU mode is disabled, the structure remains zeroed. This series depends on the separately posted "[PATCH v7 0/1] Rust PCI capability infrastructure and SR-IOV support" series [3], which provides the capability finder and VF BAR iterator used here. The prerequisite patch ID below identifies the exact dependency used to prepare this version. Changes since v1 [2]: - Adapted to the v7 Rust PCI API by handling the optional capability result and consuming the logical VF BAR iterator. (Zhi) - Made the VF information builder an associated function of GspSetSystemInfo. (Danilo [4]) - Removed the unrelated GpuacctPerfmonUtilSamples registration. (Zhi) - Rebased onto the latest drm-rust-next.
