At suspend time if there is memory pressure then dynamically allocating memory will cause failures that don't clean up properly when trying suspend a second time. Move the bigger memory allocations into Linux PM prepare() callback, drop allocations that aren't really needed in DC code and report failures in dm_suspend() up. v1: https://lore.kernel.org/amd-gfx/20230925143359.14932-1-mario.limonciello@xxxxxxx/ v2: https://lore.kernel.org/amd-gfx/20231002224449.95565-1-mario.limonciello@xxxxxxx/T/#mc800319a05df821cd1875234b09bf212e2e3282b v3: https://lore.kernel.org/amd-gfx/20231003205437.123426-1-mario.limonciello@xxxxxxx/T/#m00a49b75cd2638bf8a0ebd549d6a6010bfb7328b v4: https://lore.kernel.org/amd-gfx/20231004171838.168215-1-mario.limonciello@xxxxxxx/T/#m0921840868295ec19abbe5ecbaa0aee75356b9e1 v4->v5: * Call amdgpu_device_prepare() from other callers to amdgpu_device_suspend() * 3x evict calls -> 2x evict calls * Add IP block specific prepare path * Fix issue in UVD * Raise warnings for issues that could happen in amdgpu_switcheroo_set_state() * Catch problem that could happen in dm_suspend() * Rebase on top of DML2 series in amd-staging-drm-next v3->v4: * Combine patches 1/2 * Drop adev->in_suspend references v2->v3: * Handle adev->in_suspend in prepare() and complete() * Add missing scratch variable in dc_resource_state_destruct() * Revert error code propagation in same series v1->v2: * Handle DC code too * Add prepare callback rather than moving symbol calls Mario Limonciello (3): drm/amd: Evict resources during PM ops prepare() callback drm/amd/display: Destroy DC context while keeping DML drm/amd/display: make dc_set_power_state() return type `void` again Mario Limonciello (7): drm/amd: Evict resources during PM ops prepare() callback drm/amd: Add concept of running prepare() sequence for IP blocks drm/amd: Split up UVD suspend into prepare and suspend steps drm/amd: Capture errors in amdgpu_switcheroo_set_state() drm/amd/display: Catch errors from drm_atomic_helper_suspend() drm/amd/display: Destroy DC context while keeping DML and DML2 drm/amd/display: make dc_set_power_state() return type `void` again drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 75 ++++++++++++++++--- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 10 ++- drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c | 12 ++- drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.h | 1 + drivers/gpu/drm/amd/amdgpu/uvd_v3_1.c | 9 +++ drivers/gpu/drm/amd/amdgpu/uvd_v4_2.c | 9 +++ drivers/gpu/drm/amd/amdgpu/uvd_v5_0.c | 9 +++ drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c | 9 +++ drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c | 9 +++ .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 19 ++--- drivers/gpu/drm/amd/display/dc/core/dc.c | 43 +---------- .../gpu/drm/amd/display/dc/core/dc_resource.c | 12 +++ drivers/gpu/drm/amd/display/dc/dc.h | 2 +- drivers/gpu/drm/amd/include/amd_shared.h | 1 + 15 files changed, 149 insertions(+), 72 deletions(-) -- 2.34.1
