The windows hook WH_MOUSE_LL is called in such a way that any delay in
processing causes a system wide stall. This change spawns an extra
thread which waits on an event set by the hook which is then used to
call the callback with an artifical limit of 1000Hz.
Before we try and perhaps fail to init DXGI, we should print out what
the device is so that when there is an error report we can immediately
see if the user has the QXL device attached still.
While it's correct for DXGI to use a asyncronous waitFrame model, other
capture interfaces such as NvFBC it is not correct. This change allows
the capture interface to specify which is more correct for it and moves
the waitFrame/post into the main thread if async is not desired.
This changes the host to use a seperate pool of LGMP memory for cursor
positionl updates without shape information helping to prevent
corruption of the shape entries if they are still pending. While this is
not a perfect solution it resolves the issue without making major
changes to LGMP during the RC phase we are currently in.
Before, we only break out of the current row when a change is detected,
and all subsequent rows are still scanned. Now we break out of the entire
loop. This should make change detection ever so slightly faster.
Testing shows that `D3DKMTSetProcessSchedulingPriorityClass` has a
positive performance impact for NvFBC as well as DXGI, as such always
try to boost the priority for the windows host.
This so called "enhanced" event logic is completely flawed and can never
work correctly, better to strip it out and put our faith in windows to
handle the events for us.
And yes, I am fully aware I wrote the utter trash in the first place :)
Due to a failure to understand atomics when this code was originally
written it has a critical flaw with the fast path where an event could
be signalled when it should not be. This change set corrects this issue
by using atomic operations.
People often miss the warnings about invalid arguments in their command
line, this last minute patch attempts to address this by making
warnings, errors, fixme's and fatal errors stand out if stdout is a TTY.
If the guest VM is not showing a cursor when it starts such as on the
Windows login screen, the client never gets the current position of the
cursor, which prevents the client from attempting to send mouse
movements. This change ensures the client gets the mouse location on
startup.
Conversion from the float values srcW/srcH to the int values for the client window dimensions would sometimes round down, causing the client to scale instead of matching the host's resolution.
In order to make it easier for package maintainers that manage LG inside
their own git repository we should use the version file if it exists
over calling git describe.
A resolution switch could cause the renderer state to become invalid as
the texture format may change while it's being rendered. This fixes this
by adding a lock around the format change and render calls to the
renderer.
We should only advance the pointerIndex if the buffer was not swapped
out for storage. This is to ensure that we do not overwrite cursor
memory that the client(s) may still be using.
