Add writeback support to modetest with the below options:
- Passing in -c will now also show the writeback connector
- Test a built-in mode on writeback connector
- Test a custom mode from user input on writeback connector
Usage: "./modetest -M msm -x <connector_id>:<mode_parameters>
-a -P <plane_id>@<crtc_id>:<widthxheight>+0+0@RG24."
Refer to --help for exact syntax
- Dump the writeback output buffer to bitstream
Usage: "./modetest -M msm -s <connector_id>:<widthxheight>
-a -o <filepath>
-P <plane_id>@<crtc_id>:<widthxheight>+0+0@RG24"
This currently supports a singular writeback connector.
This patch also fixes a bug for running modetest with the atomic flag.
Changes made in V2:
- Added helper method that checks if user pipe has writeback connector
- Added error message for dump flag if no writeback connector is found
- Polls on the writeback fence fd until writeback is complete
