Subject: [PATCH v2 00/19] util/vfio-helpers: Allow using multiple MSIX IRQs
Date: Mon, 26 Oct 2020 11:54:45 +0100 [thread overview]
Message-ID: <20201026105504.4023620-1-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.
Since v1:
- Addressed Stefan comment in patch #14
"Pass minimum page size to qemu_vfio_open_pci"
(check the page size is in range with device)
- To reduce (and simplify) changes in patch #14, added
new patch #2 "Introduce device/iommu 'page_size_min' variables"
- Added "Trace controller capabilities" useful to test the
previous changes
- "Set request_alignment at initialization" reported by Stefan
(and tested by Eric off-list).
Missing review: 2,3,4,14
