Currently, multiple variables are maintained in memory manager for various reserved regions in VRAM. Such regions should not be allocated to other purposes. Instead of different variables, the series assigns unique ids to reserved regions and maintains an array of them inside memory manager.Part-1: The first 9 patches of the series assigns unique ids and maintains them as an array of reserved regions inside memory manager. Part-2: The last 5 patches of the series prefills reserve region data upfront in a consolidated function and then reserves them together in a simple loop. It doesn't fill info for all regions; the data for some regions could be still be filled in a scattered manner like from atom firmware tables or host driver tables. Also, there could be some regions like extended firmware regions which gets filled later during runtime and allocated later. They don't get allocated in the init stage as their size will be 0. v1: Part-1 v2: Part-1 + Part-2 Rename functions/variable (Alex) Lijo Lazar (14): drm/amdgpu: Add reserved region ids drm/amdgpu: Add stolen vga reserve-region drm/amdgpu: Add extended stolen vga reserve-region drm/amdgpu: Add stolen_reserved reserve-region drm/amdgpu: Add fw_reserved reserve-region drm/amdgpu: Add firmware extended reserve-region drm/amdgpu: Add fw vram usage reserve-region drm/amdgpu: Add host driver reserved-region drm/amdgpu: Add memory training reserve-region drm/amdgpu: Group filling reserve region details drm/amdgpu: Add function to fill fw reserve region drm/amdgpu: Add function to fill training region drm/amdgpu: Move validation of reserve region info drm/amdgpu: Consolidate reserve region allocations drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c | 6 +- .../gpu/drm/amd/amdgpu/amdgpu_atomfirmware.c | 18 +- drivers/gpu/drm/amd/amdgpu/amdgpu_gmc.c | 23 +- drivers/gpu/drm/amd/amdgpu/amdgpu_gmc.h | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c | 13 +- drivers/gpu/drm/amd/amdgpu/amdgpu_psp.h | 1 - drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 362 ++++++++---------- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.h | 53 +-- drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c | 50 +-- drivers/gpu/drm/amd/amdgpu/gmc_v10_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v12_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v6_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v7_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c | 2 - drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 2 - .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 4 +- .../drm/amd/ras/ras_mgr/amdgpu_virt_ras_cmd.c | 16 +- 19 files changed, 256 insertions(+), 308 deletions(-)
