b0456f9306 drm/amdgpu: write PTEs directly into the IB.
Write the PTEs at the end of the IB instead of directly into the SDMA commands.
This can save quite some CPU cycles building the entries.

This doesn't change the DW estimation because PTEs where embedded into the IB
before as well. It just moves them to the end of the IB.

44adece57e drm/fb-helper: Add a dummy remove_conflicting_framebuffers
Lots of drivers don't properly compile without this when CONFIG_FB=n.
It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when
it's disabled I think it makes sense to add it to drm_fb_helper.h.

Long term we probably need to rethink all the logic to unload firmware
framebuffer drivers, at least if we want to be able to move away from
CONFIG_FB and fbcon.

v2: Unfortunately just stubbing out remove_conflicting_framebuffers in
drm_fb_helper.h upset gcc about static vs. non-static declarations, so
a new wrapper it needs to be. Means more churn :(

3fd4b751c5 drm/amdgpu: Set MASTER_UPDATE_MODE to 0 again
With the previous change, it's safe to let page flips take effect
anytime during a vertical blank period.

This can avoid delaying a flip by a frame in some cases where we get to
amdgpu_flip_work_func -> adev->mode_info.funcs->page_flip during a
vertical blank period.

61cb8cef52 drm/amd/amdgpu: Simplify bitfield operations in gfx v8
This patch introduces a new macro WREG32_FIELD which is used
to write to a register with a new value in a field.  It's designed
to replace the pattern:

tmp = RREG32(mmFoo);
tmp &= ~REG__FIELD_MASK;
tmp |= new_value << REG__FIELD__SHIFT;
WREG32(mmFoo, tmp)

with:

WREG32_FIELD(Foo, FIELD, new_value);

Unlike WREG32_P() it understands offsets/masks and doesn't
require the caller to shift the value (or mask properly).

It's applied where suitable in the gfx_v8_0.c driver to start
with.
