Add primitive hold-n-drag.

Ideally we'd get actual MotionNotify and redraw if needed, but probably
grabbed in this case. Th...

Add the concept of a cursor coordinate when that initializes when focusing
a surface.

exists and sets its role,...

If the base game is stuck before having rendered anything, we still want
to show overlay layers ...

It's non-fatal, presumably we messed up source coordinates for that flip

Fixes the server going away when we need it most, or when attaching GDB.

So the session script can read it back and know when gamescope is ready.

We're a superset of steamcompmgr now, but have a wider scope, so new
name to reflect it.

If we only take the first commit, we leave a bunch in the queue, which
makes us that much more l...

Not last. Prevents non-vsynced clients from getting too far ahead.

Tries to flip a 1x1 surface, apparently amdgpu doesn't like it

In a liftoff future it would sur...

Now that things are generally more stable, let's take a look.

Use an empty dummy texture for unbound slots, as the driver can't know
what the shader will samp...

This way we never flip anything but our own buffers, to facilitate bug
isolation.

The flip handler could try to deref before we had added the refs.

Also fix the mouse focus edge condition to actually be correct.

Untested for now as it only happens when we lose a race, leaving a
printout to confirm if it wor...

Can't get them to be useful, might need library and amdgpu DC fixes.

Import libliftoff as subproject and plumb our planes through it.

Wait for a flip to complete im...

As opposed to nested.

Thread group size doesn't have to be aligned with image dimensions, as
is the case with 16x16 on...

Only set implicit_sync on in-bound buffers, we'll sync our scanout image
ourselves by exporting ...

We don't want SDL input in the non-nested case at any rate.

So we can easily test single-app scenarios by generating placeholder
ones. Will also make it mor...

That should come in handy for auto-grabbing in the nested case.

It worked well enough with the Big Picture cursor, and seeing it change
scales between Steam and...

Relative mouse broken right now.

We're in sole control of the cursor now, there's no "fake" cursor anymore.

Don't attempt to hid...

Also overload VulkanPipeline_t some more. :/

Change the wl event loop to busy-wait for now as that's easiest to make
unlock periodically.

In order to launch the binary with for example Mesa being installed not into
the regular /usr pr...

The project was licensed under BSD-2-Clause. Add this information back again.

That's a good enough proxy for a real vblank cadence and helps my Envy
not catch on fire.

Some more leading whitespace for good measure.

This should make steamcompmgr messages actually go when we send them.

We're pulling too many fr...

Might as well clean up some of the initial madness.

As Bas points out, their original WSI allocated them expecting them to

Caching descriptors is useless when we're importing different images
every draw.

With this and some more fixes, output pipeline looks pretty much perfect.

Working nested Vulkan path now using surface from SDL2 window.

Getting corruption on screen at 7FPS!

This makes output sane now for Xwayland buffers.

exiting.

No texturing yet, that's next after some surgery on the lump of code.

add some freeing of resources.

Sometimes we're running _before_ the app according to gpuvis, beware.

I can render an app with the only GPU work coming from steamcompmgr now.

Get steamcompmgr's GL context from EGL and rip out GLX, as we need EGL to
import dma-bufs.

Lower half is getting eaten by something, presumably underflow as it's black.

Make EGL and DRM ...

And fix a bug that would make overlays flicker.
