For now just mark one repaint per refresh interval without any particular
alignment, as that can be hard to get in nested. We'll use the display
timing extensions for that later.
We'll have it align properly in embedded mode soon.
- Add a commit wait thread that just waits for the work associated with
an in-bound dma-buff is done. We'd like to be getting a fence directly
from Wayland, but in the absence of that we'll make our own by tapping
into implicit-sync, DX11-style. gpuvis logging of the outcome of the
waits in the thread are consistent with the end of GPU work.
- Rework wayland commit handoff between wlserver and steamcompmgr to let
steamcompmgr have full access to the commit queue, letting it remove
elements in the middle and still keep going, compared to the previous
interface. This lets steamcompmgr get one commit per window per loop,
for now. We should be able to kick off waits and ref/unref resources
for all pending commits soon, with some work on the accounting first.
This should also fix an issue introduced recently where the overlay
could get really starved in embedded mode, as we were just getting
the first commit in the queue for a single frame.
Lower half is getting eaten by something, presumably underflow as it's black.
Make EGL and DRM coexist; make ensure_win_resources safe to call regardless
of what resources we want, so outer code doesn't have to care.
Get steamcompmgr's GL context from EGL and rip out GLX, as we need EGL to
import dma-bufs.
When new buffers are committed to surfaces, push their information to
steamcompmgr (without any feedback for now, fire-and-forget).
Can render games now.
Enable C++ for bits of the code, but nothing that includes wlroots as that
doesn't want to build as C++.
Enable SubstructureRedirectMask mode and handle MapRequest for now; this lets
us get the WL_SURFACE_ID ClientMessages.
This uses a build of wlroots that has its internal XWM ripped out.
