[GEM-dev] how to share texture on different thread without having to copy it on the CPU?

[Cyrille Henry]

hello,

is there a solution to share texture between 2 pd instance, or between 2 software, without having to copy it back in CPU?
somthing like pix_buffer_read and pix_buffer_write, but for gpu texture.

it look like possible, but does anyone already implement it?
