Subject: [PATCH 00/16] util/vfio-helpers: Allow using multiple MSIX IRQs
Date: Tue, 20 Oct 2020 19:24:12 +0200 [thread overview]
Message-ID: <20201020172428.2220726-1-philmd@redhat.com> (raw)
This series allow using multiple MSIX IRQs
We currently share a single IRQ between 2 NVMe queues
(ADMIN and I/O). This series still uses 1 shared IRQ
but prepare for using multiple ones.
The series is organized as:
- Fix device minimum page size (prerequisite: patch 1)
- Check IOMMU minimum page size (patches 3, 4)
- Boring cleanups already reviewed (patches 2, 5-12)
- Introduce helpers to use multiple MSIX (patches 13, 14)
- Switch NVMe block driver to use the multiple MSIX API (15)
- Remove single MSIX helper (16).
Most patches are trivial, except 13 and 14 which are the
important VFIO ones.
Please review,
Phil.
