Subject: [PATCH v3 0/3] ACPI: APEI: GHES: Add device-managed notifier helper and NVIDIA CPER handler
Date: Mon, 30 Mar 2026 17:41:54 +0800 [thread overview]
Message-ID: <20260330094203.38022-1-kaihengf@nvidia.com> (raw)
NVIDIA DGX and HGX platforms provide an ACPI device (NVDA2012) alongside
the GHES error source. The device does not generate the error records
itself; its purpose is to allow the vendor CPER handler driver to load
automatically via ACPI enumeration rather than manual module loading.
The series introduces devm_ghes_register_vendor_record_notifier() helper,
let HiSilicon PCI driver and new NVIDA GHES driver use the new helper.
Kai-Heng Feng (3):
ACPI: APEI: GHES: Add devm_ghes_register_vendor_record_notifier()
PCI: hisi: Use devm_ghes_register_vendor_record_notifier()
ACPI: APEI: GHES: Add NVIDIA vendor CPER record handler
