Build system (5 gaps hardened): - COOKBOOK_OFFLINE defaults to true (fork-mode) - normalize_patch handles diff -ruN format - New 'repo validate-patches' command (25/25 relibc patches) - 14 patched Qt/Wayland/display recipes added to protected list - relibc archive regenerated with current patch chain Boot fixes (fixable): - Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset) - D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped) - redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped) - daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch) - udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async) - relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs - greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait) - greeter-ui: built and linked (header guard unification, sem_compat stubs removed) - mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps - greeter config: removed stale keymapd dependency from display/greeter services - prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified Unfixable (diagnosed, upstream): - i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort - kded6/greeter-ui: page fault 0x8 — Qt library null deref - Thread panics fd != -1 — Rust std library on Redox - DHCP timeout / eth0 MAC — QEMU user-mode networking - hwrngd/thermald — no hardware RNG/thermal in VM - live preload allocation — BIOS memory fragmentation, continues on demand

.TH libinput-analyze-per-slot-delta "1"
|
|
.SH NAME
|
|
libinput\-analyze\-per\-slot\-delta \- analyze the per-event delta movement for touch slots
|
|
.SH SYNOPSIS
|
|
.B libinput analyze per-slot-delta [\-\-help] [options] \fIrecording.yml\fI
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.B "libinput analyze per\-slot\-delta"
|
|
tool analyzes a recording made with
|
|
.B "libinput record"
|
|
and prints the delta movement per touch slot.
|
|
.PP
|
|
This is a debugging tool only, its output may change at any time. Do not
|
|
rely on the output.
|
|
.SH OPTIONS
|
|
.TP 8
|
|
.B \-\-help
|
|
Print help
|
|
.TP 8
|
|
.B \-\-ignore-below=<units or mm>
|
|
Ignore any movement below the given threshold. The threshold is in
|
|
mm if \fB\-\-use-mm\fR is selected or in device units otherwise.
|
|
.TP 8
|
|
.B \-\-show-distance
|
|
Also show the distance relative to the initial position
|
|
of the current touch. The distance is mm if \fB\-\-use-mm\fR is selected
|
|
or in device units otherwise.
|
|
.TP 8
|
|
.B \-\-threshold=<units or mm>
|
|
Color any movement above this threshold in red. The threshold is in
|
|
mm if \fB\-\-use-mm\fR is selected or in device units otherwise.
|
|
.TP 8
|
|
.B \-\-use-mm
|
|
Print data in mm instead of device units
|
|
.TP 8
|
|
.B \-\-use-st
|
|
Use the single-touch ABS_X/ABS_Y instead of the multitouch axes
|
|
.TP 8
|
|
.B \-\-use-absolute
|
|
Print absolute coordinates, not deltas
|
|
.SH OUTPUT
|
|
An example output for a single finger touch on a touchpad supporting two
|
|
slots is below. This output is with the use of the
|
|
.B --use-mm
|
|
flag.

The entry
|
|
.B ++++++
|
|
indicates a finger has been put down,
|
|
.B ------
|
|
indicates the finger has lifted.
|
|
The left-most column is the absolute timestamp in seconds.microseconds
|
|
followed by the relative time of the event to the previous event.
|
|
.PP
|
|
The word
|
|
.B TOU
|
|
in this example represents
|
|
BTN_TOUCH, similar abbreviations exist for
|
|
BTN_TOOL_DOUBLETAP, BTN_TOOL_TRIPLETAP, BTN_TOOL_QUADTAP, and
|
|
BTN_TOOL_QUINTTAP.
|
|
.PP
|
|
The arrows
|
|
indicate the approximate direction on a 16-point compass, in this example
|
|
EastSouthEast.
|
|
.PP
|
|
Each multitouch slot supported by the hardware has one column, where the
|
|
column shows asterisk
|
|
.B ********
|
|
no finger is down for that slot. Where the column shows spaces only, a
|
|
finger is down but no data is currently available.
|
|
.PP
|
|
In the above example, the third events occurs ~33ms into the recording, is
|
|
11ms after the previous event and has an east south-east direction. The
|
|
movement for this event was x: 1.15 and y: 0.19 mm. A second finger is not
|
|
currently down.
