Subject: [PATCH v2 0/1] gpu: nova-core: populate GSP_VF_INFO for vGPU
Date: Tue, 4 Aug 2026 20:00:44 +0300	[thread overview]
Message-ID: <20260804170045.902069-1-zhiw@nvidia.com> (raw)

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. (Zhi)
