Right now the HDMI properties like vendor and product ids are hardcoded
in the function "intel_hdmi_compute_spd_infoframe()".
ret = hdmi_spd_infoframe_init(frame, "Intel", "Integrated gfx").
This patch enables the possibility of setting vendor and product id fields
of the Infoframe structure in the userspace instead of hardcoding in
the kernel, and this will help display manufacturers preload picture
configurations for the devices.
The changes has been Tested by an IGT testcase which got floated.

v2: Edited the commit message on comments received (Ville, Jani)
v1: Create new property for vendor and product id of HDMI.

And what does that mean? :o
As Ville said, uapi changes need to be posted on dri-devel in addition
to intel-gfx mailing lists.

And what does that mean? :o
As Ville said, uapi changes need to be posted on dri-devel in addition to intel-gfx mailing lists.
BR,
Jani.
I have floated in dri-devel, two days ago and yes... I will try to elaborate on "why" part :[]

To: intel-gfx, nischal.varide, uma.shankar, anshuman.gupta
Right now the HDMI properties like vendor and product ids are hardcoded
in the function "intel_hdmi_compute_spd_infoframe()".
ret = hdmi_spd_infoframe_init(frame, "Intel", "Integrated gfx").
This patch enables the possibility of setting vendor and product fields
of the Infoframe structure in the userspace, instead of hardcoding in
the kernel.
The changes has been Tested by an IGT testcase , which will be floated
in few hours

Right now the HDMI properties like vendor and product ids are hardcoded
in the function "intel_hdmi_compute_spd_infoframe()".
ret = hdmi_spd_infoframe_init(frame, "Intel", "Integrated gfx").
This patch enables the possibility of setting vendor and product id fields
of the Infoframe structure in the userspace instead of hardcoding in
the kernel, and this will help display manufacturers preload picture
configurations for the devices.
The changes has been Tested by an IGT testcase which got floated.

Right now the HDMI properties like vendor and product ids are hardcoded
in the function "intel_hdmi_compute_spd_infoframe()".
ret = hdmi_spd_infoframe_init(frame, "Intel", "Integrated gfx").
This patch enables the possibility of setting vendor and product id fields
of the Infoframe structure in the userspace instead of hardcoding in
the kernel, and this will help display manufacturers preload picture
configurations for the devices.
The changes has been tested by an IGT testcase which got floated.
v2: Edited the commit message on comments received (Ville, Jani)
v1: Create new property for vendor and product id of HDMI.
