Let's disable all scaling that requires horizontal decimation with
higher factor than 4, until we have better estimates of what we can

all decimation factors.
When decimating horizontally by more that 4 the dss is not able to

there enough bandwidth. Despite what theory says this appears to be

patch merged as:
commit
f2d580b9a8149735cbc4b59c4a8df60173658140
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Wed May 4 14:38:26 2016 +0200
drm/core: Do not preserve framebuffer on rmfb, v4.
This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.
Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc. Since vmwgfx is
a legacy driver we can safely only disable the plane with atomic.
If this commit is rejected by the driver then we will still fall
back to the old behavior and turn off the crtc.
v2:
- Remove plane->fb assignment, done by drm_atomic_clean_old_fb.
- Add WARN_ON when atomic_remove_fb fails.
- Always call drm_atomic_state_put.
v3:
- Use drm_drv_uses_atomic_modeset
- Handle the case where the first plane-disable-only commit fails
with -EINVAL. Some drivers do not support this, fall back to
disabling all crtc's in this case.

implements allocation and address space management locally by using

Tegra.

drm/amdgpu: report the number of bytes moved at buffer creation
Like ttm_bo_validate(), ttm_bo_init() might need to move BO and
the number of bytes moved by TTM should be reported. This can help

drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted()
When ttm_bo_init() fails, the reservation mutex should be unlocked.
In debug build, the kernel reported "possible recursive locking
detected" in this codepath. For debugging purposes, I also added
a "WARN_ON(ww_mutex_is_locked())" when ttm_bo_init() fails and the
mutex was locked as expected.
This should fix (random) GPU hangs. The easy way to reproduce the
issue is to change the "Super Sampling" option from 1.0 to 2.0 in
Hitman. It will create a huge buffer, evict a bunch of buffers
(around ~5k) and deadlock.
This regression has been introduced pretty recently.

drm/amdgpu: shut up #warning for compile testing
My randconfig tests on linux-next showed a newly introduced warning:

drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:377:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp]
Generally speaking, warnings about bad kernel configuration are not particularly
helpful. We could enforce the selection of X86_PAT through Kconfig, so the driver
cannot even be used unless it is enabled, or we could just rely on the runtime
warning that is also there.
In this version, I'm making the warning conditional on CONFIG_COMPILE_TEST, which
shuts it up for me, but not people that may actually want to run the kernel
as a compromize.

drm/msm: return -EFAULT if copy_from_user() fails
copy_from_user_inatomic() is actually a local function that returns
-EFAULT or positive values on error. Otherwise copy_from_user() returns
the number of bytes remaining to be copied. We want to return -EFAULT
here.
I removed an unlikely() because we just did a copy_from_user()
so I don't think it can possibly make a difference.

drm/msm/dsi: Add PHY/PLL for 8x96
Extend the DSI PHY/PLL drivers to support the DSI 14nm PHY/PLL
found on 8x96.
These are picked up from the downstream driver. The PHY part is similar
to the other DSI PHYs. The PLL driver requires some trickery so that
one DSI PLL can drive both the DSIs (i.e, dual DSI mode).
In the case of dual DSI mode. One DSI instance becomes the clock master,
and other the clock slave. The master PLL's output (Byte and Pixel clock)
is fed to both the DSI hosts/PHYs.
When the DSIs are configured in dual DSI mode, the PHY driver communicates
to the PLL driver using msm_dsi_pll_set_usecase() which instance is the
master and which one is the slave. When setting rate, the master PLL also
configures some of the slave PLL/PHY registers which need to be identical
to the master's for correct dual DSI behaviour.
There are 2 PLL post dividers that should have ideally been modelled as
generic clk_divider clocks, but require some customization for dual DSI.
In particular, when the master PLL's post-diviers are set, the slave PLL's
post-dividers need to be set too. The clk_ops for these use clk_divider's
helper ops and flags internally to prevent redundant code.
