Hi, This series depends on the following series from Elena Ufimtseva <elena.ufimts...@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!
