title: Plugin: Kinetic DP
---

This plugin supports updating FW for Kinetic DP converter chips.

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

• com.kinet-ic.dp

These devices use the standard DPAUX GUID values, e.g.

• DPAUX\OUI_0090CC24 (only-quirk)
• DPAUX\OUI_0090CC24&HWREV_10 (only-quirk)
• DPAUX\OUI_0090CC24&HWREV_10&DEVID_SYNAB2 (only-quirk)
• DPAUX\OUI_0090CC24&DEVID_SYNAB2 (only-quirk)

These devices also use custom GUID values, e.g.

• MST\VEN_60AD&DEV_${dev_id}&CID_${customer_id}&CHW_${customer_board}
• MST\VEN_60AD&DEV_${dev_id}&CID_${customer_id} (only-quirk)
• MST\VEN_60AD&FAM_${family_id} (only-quirk)

The vendor ID is set from the PCI vendor, for example set to DRM_DP_AUX_DEV:0x$(vid)

Kernel 4.6 introduced an DRM DP Aux interface for manipulation of the registers needed to access an DP hub. This patch can be backported to earlier kernels: https://github.com/torvalds/linux/commit/e94cb37b34eb8a88fe847438dba55c3f18bf024a

Supported devices will be displayed in # fwupdmgr get-devices output.

This plugin requires read/write access to /dev/drm_dp_aux*.

This plugin has been available since fwupd version 1.9.8.
