Created May 20, 2021 20:43 — forked from Miouyouyou/drm-prime-dumb-kms.c
Simple example showing how to use DRM to : allocate a Dumb buffer on the GPU, use it as a framebuffer, use this CRTC on the currently connected screen (expecting 1 connected screen), export the buffer, reimport it implicitly with mmap and write in it.
// This will works on Embedded GPU that implements .gem_prime_mmap like Rockchip ones.
// This will fail on most DRM drivers for GPU with dedicated memory as they tend to NOT implement .gem_prime_mmap.

Setting up Qemu with a tap interface

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

  • The virtual network device that is provided to the guest (e.g. a PCI network card).
  • The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network
