From aa5f04d2e5a842351449034e619913e1c721a37c Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Mon, 31 Jul 2023 18:12:56 +0200 Subject: [PATCH] accel/ivpu: Extend get_param ioctl to identify capabilities Add DRM_IVPU_PARAM_CAPABILITIES parameters to get_param ioctl to query driver capabilities. For now use it for identify metric streamer and new dma memory range features. Currently upstream version of intel_vpu does not have those, they will be added it the future.
