Subject: [PATCH v2 0/7] PCI/MSI: Remove IMS (Interrupt Message Store) support for now
Date: Wed, 10 Apr 2024 17:13:00 -0500 [thread overview]
Message-ID: <20240410221307.2162676-1-helgaas@kernel.org> (raw)
From: Bjorn Helgaas <bhelgaas@google.com>
IMS (Interrupt Message Store) support appeared in v6.2, but there are no
users yet.
Remove it for now. We can add it back when a user comes along.
I propose to merge this via the PCI tree unless somebody else wants it.
Changes since v1 (https://lore.kernel.org/linux-pci/20240401232326.1794707-1-helgaas@kernel.org/):
- Revert other IMS commits in IOMMU, apic, genirq, suggested by Kevin
