drm/amdgpu:Always save uvd vcpu_bo in VM Mode

2018-03-15T09:54:31+00:00

commit f8bee6135e167f5b35b7789c74c2956dad14d0d5 upstream. When UVD is in VM mode, there is not uvd handle exchanged, uvd.handles are always 0. So vcpu_bo always need save, Otherwise amdgpu driver will fail during suspend/resume.

drm/amdgpu: use a 64bit interval tree for VM management v2

2017-04-04T17:40:32+00:00

This only makes a difference for 32-bit systems. The idea is to have a fixed virtual address space size with 4-level page tables and to minimize differences between 32 and 64-bit systems. v2: Update commit message.

drm/amd/amdgpu: get maximum and used UVD handles (v4)

2017-01-27T16:12:38+00:00

Change History -------------- v4: Changes suggested by Emil, Christian - return -ENODATA for asics with unlimited sessions v3: changes suggested by Christian - Add a check for UVD IP block using AMDGPU_HW_IP_UVD query type. - Add a check for asic_type to be less than CHIP_POLARIS10 since starting Polaris, we support unlimited UVD instances. - Add kerneldoc style comment for amdgpu_uvd_used_handles(). v2: as suggested by Christian - Add a new query AMDGPU_INFO_NUM_HANDLES - Create a helper function to return the number of currently used UVD handles. - Modify the logic to count the number of used UVD handles since handles can be freed in non-linear fashion. v1: - User might want to query the maximum number of UVD instances supported by firmware. In addition to that, if there are multiple applications using UVD handles at the same time, he might also want to query the currently used number of handles. For this we add two variables max_handles and used_handles inside drm_amdgpu_info_hw_ip. So now an application (or libdrm) can use AMDGPU_INFO IOCTL with AMDGPU_INFO_HW_IP_INFO query type to get these values.
