Crate libdrmtap_sys

Structs§

drmtap_config: Configuration for opening a capture context
drmtap_cursor_info: Cursor state
drmtap_device: A capturable DRM device, as reported by drmtap_list_devices. Layout is frozen: it is written into caller-owned storage, so a future addition must come as a new accessor rather than a new field here.
drmtap_display: Information about a connected display
drmtap_dmabuf_desc: Descriptor of an externally-supplied scanout DMA-BUF (split capture): metadata from the privileged exporter shipped over IPC into drmtap_convert_dmabuf() on the unprivileged side.
drmtap_frame_info: Captured frame data
drmtap_rect: Dirty rectangle from frame differencing

DRMTAP_EOTF_HLG
DRMTAP_EOTF_PQ
DRMTAP_EOTF_SDR: Scanout EOTF (from the connector HDR_OUTPUT_METADATA, CTA-861 numbering)

drmtap_list_devices^⚠: Enumerate every DRM device with KMS resources. A context is bound to one device, so this is how a multi-GPU consumer finds the other cards instead of only ever advertising the displays of the first one.
drmtap_list_displays^⚠
drmtap_open^⚠
drmtap_open_render^⚠
drmtap_render_node^⚠: Render node of the device backing ctx, for handing to drmtap_open_render on the converting side of a split so it binds to the GPU that exported the frame. Owned by ctx; NULL if it has none.
drmtap_set_output_buffer^⚠: Point the conversion paths at a caller-owned buffer instead of a library-owned one, so a consumer that must end up with the pixels in its own memory does not copy the frame.
drmtap_version^⚠
