Sat Mar 8 21:34:11 UTC 2025 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.14
- A hotplug and DPMS tidy up to accommodate quirks exhibited by drivers, GPUs and monitors.
- Default to libddcutil event detection for libddcutil >= 2.2 (for faster response to changes).
- Add option --prefer-libddcutil-events as a better name for deprecated option --prefer-drm.
- Deprecate option --prefer-drm as it's name is misleading.
- Add option --disable-connectivity-signals to allow connectivity signals to be turned off.
- Add options --disable-hotplug-polling and --disable-dpms-polling to accommodate quirky monitors.
- Always internally poll for DPMS changes (DPMS is not covered by libddcutil events).
- Add method ListDetected to take advantage of hotplug detection in libddcutil >= 2.2.
- Add the list command to ddcutil-client to provide access to the new ListDetected method.
- Add wait, wait-connection-change, and wait-vcp-change commands to ddcutil-client.
- Log more information when get_vcp fails.
-------------------------------------------------------------------
Wed Nov 27 19:36:37 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.12
- Return the error status-code if enable_ddca_watch_displays fails - was returning OK even on failure.
-------------------------------------------------------------------
Thu Aug 22 01:18:47 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.11
- Alter the detect-function for ddcutil 2.5.1 (generates more logging/warning info).
- Add a DETECT_ALL option to control whether disabled/powered-off VDU's are to be included in the results from detect.
- Reduce the number of messages generated when polling for hotplug events.
- Fixes to API documentation.
-------------------------------------------------------------------
Thu Jun 13 23:04:48 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.9
- Fixed a GetCapabilitiesMetadata bug that caused some VCP features to lack metadata values.
- Fixed the return of feature-name and feature-description from GetVcpMetadata.
- Fixed potential hot-plug/DPMS polling memory leaks and simplified event locking.
- Recoded hot-plug/DPMS polling to avoid a potential libddcutil assertion failure.
- Fixed code/doc typos, improved code readability/structure, reduced IDE warnings.
- Updated documentation to caution against excessive updates when coding loops, as this may impact VDU NVRAM lifespan.
- Updated documentation to caution against experimenting with non-standard features, as it may risk damage to the VDU.
-------------------------------------------------------------------
Thu May 16 00:25:06 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.7
- Slightly improved setvcp diagnostics.
- Fix methods failing with return code DDCRC_OTHER (-3022) when only some i2c devices are accessible.
-------------------------------------------------------------------
Mon Apr 29 03:52:43 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.6
- Add SetVcp/SetVcpWithContext NO_VERIFY (no retry) flag option.
- Match the behaviour of the ddcutil command, default to verify-and-retry for all set-vcp method calls.
- Default to verify-and-retry for all libddcutil versions.
- Replace the stateful DdcutilVerifySetVcp property with the stateless NO_VERIFY flag.
- Fix the ServiceFlagOptions property so that it lists all flag options.
- Check the status returned by libddcutil ddca_init() and exit on error to prevent any inconsistent behaviour.
- Cleanup the --prefer-polling and --prefer-drm options to make them consistent with each other.
-------------------------------------------------------------------
Fri Apr 12 22:50:44 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.4
- Provide an API flag RETURN_RAW_VALUES which disables GetVcp high-byte masking of Simple Non-Continuous features.
- Provide the --return-raw-values command line option for the same purpose.
-------------------------------------------------------------------
Mon Apr 1 18:07:41 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- 1.0.3
- Reduce unnecessary logging.
- Improve the description of the service's signals in ddcutil-service.1.
- Correct the typo in option name --perfer-drm (it was mistakenly called --prefer-dma).
- For simple VCP-features, only return the low-byte, for some VDUs the high-byte might contain junk.
-------------------------------------------------------------------
Thu Feb 29 06:37:06 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- Version 1.0.2
- Added VcpValueChanged D-Bus signal which triggers if the SetVcp method succeeds. This is to allow
multiple clients to be aware of changes made by each.
- Added SetVcpWithContext which accepts a client-context to be returned with the VcpValueChanged signal.
- ServiceEmitSignals renamed to ServiceEmitConnectivitySignals to avoid confusion.
- Command line option --emit-signals renamed to --emit-connectivity-signals for the same reason.
- Fix ServiceEmitSignals property assignment so that it correctly toggles hotplug signals.
- Fix hotplug polling so that it remains an option no matter what version of libddcutil is in use.
- Version 1.0.1
- Use gcc with -Wformat-security for safety and to match Arch and Ubuntu defaults.
- Calling ddca_init() before verify_i2c() to fix runtime error for libddcutil >= 2.1.
-------------------------------------------------------------------
Thu Jan 18 21:15:00 UTC 2024 - Michael Hamilton <michael@actrix.gen.nz>
- Version 1.0.0
* Added an optional D-Bus interface to ddcutil for up 10x faster response times.
