From ebbe34edc0a90be85b620b85eb97f8ff3356e38c Mon Sep 17 00:00:00 2001 From: Pratap Nirujogi Date: Tue, 19 Nov 2024 18:03:15 -0500 Subject: drm/amd/amdgpu: Add support for isp buffers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support to create user BOs with MC address for isp using the dma-buf handle exported for the buffers allocated from system memory in isp driver. Export amdgpu_bo_create_kernel() and amdgpu_bo_free_kernel() as well for isp to allocate GTT internal buffers required for fw to run.

charset=UTF-8 Content-Transfer-Encoding: 8bit Before, every time fdinfo is queried we try to lock all the BOs in the VM and calculate memory usage from scratch. This works okay if the fdinfo is rarely read and the VMs don't have a ton of BOs. If either of these conditions is not true, we get a massive performance hit. In this new revision, we track the BOs as they change states. This way when the fdinfo is queried we only need to take the status lock and copy out the usage stats with minimal impact to the runtime performance. With this new approach however, we would no longer be able to track active buffers.
