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!
