Hi, this work is based on the virtio_wl driver in the ChromeOS kernel by Zach Reizner, currently at: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/virtio/virtio_wl.c There's one feature missing currently, which is letting clients write directly to the host part of a resource, so the extra copy in TRANSFER_TO_HOST isn't needed. Have pushed the

Hi all, As some of you may know there some subtle distinction between C and C++ structs, thus one should wrap/annotate them roughly like below. ... #if defined(__cplusplus) extern "C" { #endif struct foo { int bar; ... }; ... #if defined(__cplusplus) } #endif In order to work around the lack of these users can wrap the header inclusion in the same way. For example:

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk> Refactor fence creation to remove the potential allocation failure from the cmd_submit and atomic_commit paths. Now the fence should be allocated first and just after we should proceed with the rest of the execution.
