Hi all, this series adds the multi-transports support to vsock, following this proposal: https://www.spinics.net/lists/netdev/msg575792.html With the multi-transports support, we can use vsock with nested VMs (using also different hypervisors) loading both guest->host and host->guest transports at the same time. Before this series, vmci-transport supported this behavior but only using

DRM's fbdev console uses regular load and store operations to update framebuffer memory. The bochs driver on sparc64 requires the use of I/O-specific load and store operations. We have a workaround, but need a long-term solution to the problem. This patchset changes GEM's vmap/vunmap interfaces to forward pointers of type struct dma_buf_map and updates the generic fbdev emulation to use
