Subject: [PATCH RFC server v2 00/11] vfio-user server in QEMU
Date: Fri, 27 Aug 2021 13:53:19 -0400 [thread overview]
Message-ID: <cover.1630084211.git.jag.raman@oracle.com> (raw)
In-Reply-To: <cover.1629131628.git.elena.ufimtseva@oracle.com>
Hi,
This series depends on the following series from
Elena Ufimtseva <elena.ufimtseva@oracle.com>:
[PATCH RFC v2 00/16] vfio-user implementation
Thank you for your feedback for the v1 patches!
https://www.mail-archive.com/qemu-devel@nongnu.org/msg825021.html
We have incorporated the following feedback from v1 of the
review cycle:
[PATCH RFC server v2 01/11] vfio-user: build library
- Using cmake subproject to build libvfio-user
[PATCH RFC server v2 02/11] vfio-user: define vfio-user object
- Added check to confirm that TYPE_REMOTE_MACHINE is used
with TYPE_VFU_OBJECT
[PATCH RFC server v2 04/11] vfio-user: find and init PCI device
- Removed call to vfu_pci_set_id()
- Added check to confirm that TYPE_PCI_DEVICE is used with
TYPE_VFU_OBJECT
[PATCH RFC server v2 05/11] vfio-user: run vfio-user context
- Using QEMU main-loop to drive the vfu_ctx (using
vfu_get_poll_fd() & qemu_set_fd_handler())
- Set vfu_ctx to non-blocking mode (LIBVFIO_USER_FLAG_ATTACH_NB)
- Modified how QEMU attaches to the vfu_ctx
[PATCH RFC server v2 06/11] handle PCI config space accesses
- Broke-up PCI config space access to 4-byte accesses
[PATCH RFC server v2 07/11] vfio-user: handle DMA mappings
- Received feedback to assert that vfu_dma_info_t->vaddr is not
NULL - unable to do it as it appears to be a valid case.
[PATCH RFC server v2 10/11] register handlers to facilitate migration
- Migrate only one device's data per contect
Would appreciate if you could kindly review this v2 series. Looking
forward to your comments.
Thank you!
