This reverts commit 2d8e60e8b074 ("drm/vmwgfx: Replace numeric
parameter like 0444 with macro")
The commit belongs to the series of 1285 patches sent to LKML on
2016-08-02, it changes the representation of file permissions from the
octal value "0600" to "S_IRUSR | S_IWUSR".
The general consensus was that the changes does not increase
readability, quite the opposite; 0600 is easier to parse mentally than
S_IRUSR | S_IWUSR.
It also causes argument inconsistency, due to commit 04319d89fbec
("drm/vmwgfx: Add an option to change assumed FB bpp") that added
another call to module_param_named() where the permissions are written
as 0600.

vmw_ldu_crtc_helper_commit() is not called if
drm_atomic_crtc_needs_modeset() decides nothing related to CRTC timing has
changed.
So a better place for this code is in vmw_ldu_primary_plane_atomic_update()
since we will need to update ld->fb every time the FB is updated.

Pinning fbdev's FB at the start of VRAM prevents X from pinning
its FB. Since for ldu, the fb would be pinned anyway during a
mode set, just skip pinning it in fbdev.
This is not the best solution, but since ldu is not used much
anymore, it seems like a reasonable workaround.

We can no longer make the assumption that vmw_stdu_update_st() will
be called when there's a valid display surface attached. So
instead of using display_srf for width and height, make a record of

Switch over to using internal atomic API for mode set.
This removes the legacy set_config API, replacing it with
drm_atomic_helper_set_config(). The DRM helper will use various
vmwgfx-specific atomic functions to set a mode.
DRIVER_ATOMIC capability flag is not yet set, so the user mode
will still use the legacy mode set IOCTL.
v2:
* Avoid a clash between page-flip pinning and setcrtc pinning, modify
the page-flip code to use the page-flip helper and the atomic callbacks.
To enable this, we will need to add a wrapper around atomic_commit.

Atomic mode set requires us to refactor existing vmw_stdu_crtc_set_config
code into sections that check the validity of the new mode, and sections
that actually program the hardware state.
vmw_du_crtc_atomic_check() takes CRTC-related checking code. In a later
patch, vmw_du_primary_plane_atomic_check() will take framebuffer-related
checking code.
These helpers won't be called until we flip on the atomic support
flag or set drm_crtc_funcs->set_config to using the atomic
helper.
v2:
* The state->num_connector is actually the total number of potential
connectors, not just the one associated with the display unit.
The proper one to check is ->connector_mask.
* Add the check to only allow plane state to be the same as crtc state
(Thanks to mlankhorst)
* Make sure to turn on SVGA mode before using VRAM. SVGA mode is
disabled in master_drop if dbdev is not running.

commit 8490ae207f1d ("drm/i915: Suppress busy status for engines if
wedged") moved the check for inflight requests to the
intel_engines_are_idle() check to protect the idle worker. However, the
request selftests were also checking the engine idle status and erroring
out if they did not become idle within a short period of time after the
final wait. In order to accommodate the new check, call retire requests
prior to the engine check so that we flush all the waits.

Michał Winiarski pointed out that the debugging infrastructure (such as
trace_dma_fence_release) likes to pretty print the timeline name, long
after we have freed the timeline. Our timelines currently live as part of
the GTT (due to the strict ordering we currently use through each) which
belong to the context. We aim to free the context and release its
hardware resources as soon as we able to (i.e. when the last
fence/request using it has been signaled and retired). As the
.get_timeline_name is purely a debug feature, rather than extending the
lifetime of the context, or splitting it into many different release
phases just to keep the name around, replace the timeline name with a
constant after the fence has been signaled. This avoids the potential
use-after-free.

Unlocking is dangerous. In this case we combine an early update to the
out-of-queue request, because we know that it will be inserted into the
correct FIFO priority-ordered slot when it becomes ready in the future.
However, given sufficient enthusiasm, it may become ready as we are
continuing to reschedule, and so may gazump the FIFO if we have since
dropped its spinlock. The result is that it may be executed too early,
before its dependencies.
v2: Move all work into the second phase over the topological sort. This
removes the shortcut on the out-of-rbtree request to ensure that we only
adjust its priority after adjusting all of its dependencies.

powered off by the platform, so there's no point in registering it with
vga_switcheroo. In fact, when the external GPU is runtime suspended,
vga_switcheroo will cut power to the internal discrete GPU, resulting in
a lockup. Moreover AMD's Windows driver special-cases Thunderbolt as
well.

We want to lock the primary plane, not the cursor (which might be
optional). Real bad case of copy-paste fail, unfortunately our CI
didn't catch that because i915 does have a cursor plane.

Like the atomic update hook it's wrapping, the plane_state is the old
one, and the new one is in plane->state. Both msxfb and tinydrm use
it correctly, but I mistook it for the new state in pl111 due to its
naming.

Not sure what the original intention was here, but returning a random piece of
kernel memory to userspace because we didn't set the value at all is clearly
not a good idea.
This patch disallows reading the register and returns
a proper error code instead.
