Elie Kheirallah 5a91dd8d2b vm_control: sleep/wake devices when VM gets suspended/resumed ... Currently commands Suspend and Resume to the VM will only sleep the Vcpus but not devices. This results in a partial suspend/resume since devices can still be running and potentially modifying the env (filling up buffers, modifying variables). The aim of this CL is to put the devices to sleep when the VM is put in suspended mode, and to wake the devices when the VM goes back to resumed mode. Added new flag to `suspend` and `resume` commands: `--full` which does a full VM suspend. Added new VmRequest: SuspendVm, ResumeVm. Added suspend/resume test that also suspends/resumes devices, thus doing a Full VM suspend/resume. Also now tracking the state of devices before sleep, just like Vcpus BUG=N/A TEST=presubmit, e2e_tests TEST=boot a VM, suspend, resume Change-Id: Ia13fbdf7bb6765dd20bd3c67af5212e9c842b824 Reviewed-on: https://chromium-review.googlesource.com/c/crosvm/crosvm/+/4616827 Reviewed-by: Frederick Mayle <fmayle@google.com> Commit-Queue: Elie Kheirallah <khei@google.com> Reviewed-by: Daniel Verkamp <dverkamp@chromium.org>		2023-06-27 19:31:41 +00:00
