Subject: [PATCH 1/4] thread: For consistency, s/real_time/realtime/
Most of the code writes "real-time" as "realtime" not "real_time".
The only exception is one function `request_real_time_scheduling`.
This commit changes that function for consistency.

Subject: [PATCH 2/4] tests/dbusmock-templates/rtkit: Add
MakeThreadHighPriority
mutter will soon need to call an additional method in RTKit,
MakeThreadHighPriority.
In preparation for that, this commit stubs it out in the
dbusmock template.

From a7c0f106b30137e1fc6159eaecee8e61b8dc48a9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/4] thread: Allow turning off rt scheduling for running
thread
At the moment if a thread is made real-time there's no going back,
it stays real-time for the duration of its life.
That's suboptimal because real-time threads are expected by RTKit to
have an rlimit on their CPU time and certain GPU drivers in the kernel
can exceed that CPU time during certain operations like DPMS off.
This commit adds two new ref counted functions:
meta_thread_{un,}inhibit_realtime_in_impl
that allow turning a thread real-time or normally scheduled. At the same
time, this commit stores the RTKit proxy as private data on the thread
so that it can be reused by the above apis.
A subsequent commit will use the new APIs.

Subject: [PATCH 4/4] kms/impl-device: Inhibit real-time scheduling when mode
setting
Certain kernel drivers can take an unreasonably long time to
complete mode setting operations. That excessive CPU time is charged
to the process's rlimits which can lead to the process getting killed
if the thread is a real-time thread.
This commit inhibits real-time scheduling around mode setting
commits, since those commits are the ones currently presenting as
excessively slow.

Subject: [PATCH] monitor-config-store: Discard config with fractional scale
when unusable
When a configuration has a fractional scale, but we're using a physical
monitor layout, we can't use the scale, but if we do, we end up with
wierd issues down the line. Just discard the config if we run into this.
Eventually we probably want to store the layout mode in the
configuration so we can handle more seamless switching between physical
and logical layout mode, but first do this.

Subject: [PATCH] backends/native: Translate keycodes with
xkb_key_state_get_one_sym()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:
1. "This function is similar to xkb_state_key_get_syms(), but intended for
users which cannot or do not want to handle the case where multiple
keysyms are returned (in which case this function is preferred)."
We are indeed in that field, and have been for a long time.
2. "This function performs Capitalization Keysym Transformations."
This is unlike the xkb_key_get_syms() function that we use, and
convenient here for parity with X11 since it behaves exactly that
way.
Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

Subject: [PATCH 2/2] screen-cast/strieam-src: Fix stride and max buffer size
calculation
1. Centralize stride calculation in one function.
2. For dmabufs query the stride instead of assuming a certain value.
3. For system memory buffers use the pixel format to calculate the
stride.
4. Stop negotiating `SPA_PARAM_BUFFERS_size` and
`SPA_PARAM_BUFFERS_stride`.
2. fixes an actual bug where we reported wrong max buffer sizes,
resulting in crashes in Gstreamer when doing area screencasts on AMD
GPUs.
The reasoning for 4. is that the values were possibly wrong for
dmabufs as the negotiation happens before we create any buffers.
Further more neither Mutter nor the common consumers required it.
The later either ignore the values (OBS), always accept (gstpipewiresrc)
them or calculate the exact same possibly wrong values (libwebrtc).

handle to hash table
`calculate_stride()` looks up the dmabuf handle from the hash table so
we need to add it first.
