[PATCH 0/5] MR2944: winewayland.drv: First window contents on screen
The goal of this MR is to set up the minimum necessary infrastructure to display the contents of some simple, software rendered windows. This involves two major steps: 1. Associate a window with a Wayland surface and give it the `xdg_toplevel` role, so that the compositor can display it. We also have to implement the required initial `xdg_surface` configuration sequence to be able to safely (i.e., without the compositor disconnecting us with an error) attach buffers to the surface in step (2). 2. Implement the `window_surface` interface for the Wayland driver. For now we provide a simple (and suboptimal) `window_surface_flush` implementation: for each flush we create a new `wl_shm` buffer, copy the whole window contents (ignoring damaged bounds for now) into it and attach it to the target Wayland surface. In the next MR I will optimize this implementation in multiple ways: a. implement a buffer queue to avoid constantly allocating new buffers b. respect the damaged bounds of the `window_surface` to minimize copying of data from the `window_surface` to the SHM buffer (and also for correctness) c. communicate damaged surface regions to the compositor to (potentially) allow more efficient texture uploads. With this MR many (software-rendered) applications can now display dynamic content on screen. We can't interact with the apps yet, but we do get to enjoy `notepad` in all its blinking-cursor glory.

From: Alexandros Frantzis <alexandros.frantzis(a)collabora.com> In our setup with a dedicated event dispatch thread, libwayland ensures that object proxies associated with an event handler remain valid (or NULL) while the handler is executing. However, no such guarantees are given for the proxy user data. It is thus possible for the user data to become invalid (e.g., its memory freed from a different thread) right after the event handler is entered. This is an issue for wayland_surface associated proxies since they may receive unsolicited events from the compositor at any time (e.g., xdg_surface.configure), even while we are destroying the wayland_surface. To avoid the problem, we add a Wayland event loop synchronization operation after the destruction of wayland_surface related proxies, but before we destroy the wayland_surface itself. The sync operation guarantees that all libwayland event dispatches after it will take into account the destroyed proxies, and thus will not provide access to these proxies or their user data. Event dispatches before the sync will have valid user data since the wayland_surface is still not destroyed at that point. --- dlls/winewayland.drv/wayland.c | 152 +++++++++++++++++++++++++ dlls/winewayland.drv/wayland_surface.c | 4 + dlls/winewayland.drv/waylanddrv.h | 7 ++ dlls/winewayland.drv/waylanddrv_main.c | 4 +- 4 files changed, 164 insertions(+), 3 deletions(-) diff --git a/dlls/winewayland.drv/wayland.c b/dlls/winewayland.drv/wayland.c index 357dc4208d3..5d2fe122368 100644 --- a/dlls/winewayland.drv/wayland.c +++ b/dlls/winewayland.drv/wayland.c @@ -28,7 +28,11 @@ #include "wine/debug.h" +#include <errno.h> +#include <fcntl.h> +#include <poll.h> #include <stdlib.h> +#include <unistd.h> WINE_DEFAULT_DEBUG_CHANNEL(waylanddrv);
