From f9db1fc52ceb42f4a18506693349316f5e209ba6 Mon Sep 17 00:00:00 2001 From: David Francis Date: Mon, 16 Jun 2025 09:47:42 -0400 Subject: drm/amdgpu: Add ioctl to get all gem handles for a process MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add new ioctl DRM_IOCTL_AMDGPU_GEM_LIST_HANDLES. This ioctl returns a list of bos with their handles, sizes, and flags and domains. This ioctl is meant to be used during CRIU checkpoint and provide information needed to reconstruct the bos in CRIU restore.
