- Improved GPU scheduler documentation
- Initial gfxoff support for raven
- SR-IOV fixes
- Default to non-AGP on PowerPC for radeon
- Fine grained clock voltage control for vega10
- Power profiles for vega10
- Further clean up of powerplay/driver interface
- Underlay fixes
- Display link bw updates
- Gamma fixes

959a2091fa drm/amdgpu: Add support to change mtype for 2nd part of gart BOs on GFX9
This change prepares for a workaround in amdkfd for a GFX9 HW bug. It
requires the control stack memory of compute queues, which is allocated
from the second page of MQD gart BOs, to have mtype NC, rather than
the default UC.

09daf474d2 drm/amdgpu: fix amdgpu_atpx_get_client_id()'s return type
The method struct vga_switcheroo_handler::get_client_id() is defined
as returning an 'enum vga_switcheroo_client_id' but the implementation
in this driver, amdgpu_atpx_get_client_id(), returns an 'int'.

Fix this by returning 'enum vga_switcheroo_client_id' in this driver too.

48edde3959 drm/amdgpu: change pp_dpm clk/mclk/pcie input format.
1. support more than 8 values when setting get_pp_dpm_mclk/
sclk/pcie, the former design just parse command format like
"echo xxxx > pp_dpm_sclk" and current can parse "echo xx xxx
 xxxx > pp_dpm_sclk" whose operation is more user-friendly
and convinent and can offer more values;
2. be compatible with former design like "xx".
3. add DOC: pp_dpm_sclk pp_dpm_mclk pp_dpm_pcie
Bug:KFD-385

38610f15a7 drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shaders
Otherwise, the SQ may skip some of the register writes, or shader waves may
be allocated where we don't expect them, so that as a result we don't actually
reset all of the register SRAMs. This can lead to spurious ECC errors later on
if a shader uses an uninitialized register.

6c8d74caa2 drm/amdgpu: Enable scatter gather display support
Enables sg display if vram size <= THRESHOLD(256M); otherwise
still use vram as display buffer.
This patch fixed some potention issues introduced by change
"allow framebuffer in GART memory as well" due to CZ/ST hardware
limitation.

v2: Change default setting to auto.
v3: Move some logic from amdgpu_display_framebuffer_domains()
    to pin function, suggested by Christian.
v4: Split into several patches.
v5: Drop module parameter for now.
