[PATCH 2/2] drm/vkms: Implement CRC debugfs API

2018-07-28 Thread Haneen Mohammed
This patch implement the necessary functions to compute and add CRCs entries: - Implement the set_crc_source() callback. - Compute CRC using crc32 on the visible part of the framebuffer. - Use ordered workqueue per output to compute and add CRC at the end of a vblank. - Use appropriate synchroni
