Commit Message

Deborah Brouwer Dec. 4, 2021, 6:13 a.m. UTC
The error injection controls that test wrap-around sequence and timestamp
counters were partially broken. Add a menu option for 64 or 32 bit signed
timestamp wrapping. Prevent the timestamp from wrapping around before the
device can be tested.  Remove the sequence count from the timestamp
calculation so that sequence wrapping does not interfere with the
timestamp.  Add consistent time and sequence wrapping to sdr and touch
devices.

Signed-off-by: Deborah Brouwer <deborahbrouwer3563@gmail.com>
---
Changes since v1:
- wrap timestamp at signed rather than unsigned values
- simplify time_wrap_offset calculation

How I set the controls:
v4l2-ctl -d <dev> -c wrap_sequence_number=1
v4l2-ctl -d <dev> -c wrap_timestamp=1
v4l2-ctl -d <dev> -c wrap_timestamp=2

How I tested:
v4l2-ctl -d <dev> --stream-mmap --verbose 
v4l2-ctl -d <dev> --stream-out-mmap --verbose 
v4l2-ctl-32 -d <dev> --stream-mmap --verbose
v4l2-ctl-32 -d <dev> --stream-out-mmap --verbose

Devices I tested:
vivid-000-vid-cap, inputs: webcam, TV, S-Video, HDMI
vivid-000-vid-out, outputs: S-Video, HDMI
vivid-000-touch-cap
vivid-000-sdr-cap
vivid-000-vbi-out
vivid-000-meta-cap
vivid-000-meta-out
