[PATCH v1 0/3] New debugfs API for capturing CRC of frames

Show all headers | View raw

Hi,

this series basically takes the facility for continuously capturing CRCs
of frames from the i915 driver and into the DRM core.

The idea is that test suites such as IGT use this information to check
that frames that are expected to be identical, also have identical CRC
values.

Other drivers for hardware that can provide frame CRCs (including eDP
panels that support self-refresh) can easily implement the new callback
and provide userspace with the CRC values.

Thanks,

Tomeu
