Hi, for our purposes we need to access host's memory (Vulkan buffers) directly from a linux guest (Android), I have not found existing tools for this and implemented our own solution (a PCI device and a linux driver):
https://android.googlesource.com/kernel/goldfish/+/android-goldfish-4.14-dev/drivers/misc/goldfish_address_space.c https://android.googlesource.com/platform/external/qemu/+/emu-master-dev/hw/pci/goldfish_address_space.c while this works, I was asked to double check if QEMU does not have an existing solution for this before upstreaming to kernel.org. Could you please advise? Thank you. Regards, Roman.
