Eric Anholt ffc2674071 drm/vc4: Disable V3D interactions if the v3d component didn't probe.
One might want to use the VC4 display stack without using Mesa.
Similar to the debugfs fixes for not having all of the possible
display bits enabled, make sure you can't oops in vc4 if v3d isn't
enabled.

v2: Fix matching against other v3d variants (review by Paul), don't

Eric Anholt c9be804c8c drm/vc4: Use common helpers for debugfs setup by the driver components.
The global list of all debugfs entries for the driver was painful: the
list couldn't see into the components' structs, so each component had
its own debugs show function to find the component, then find the
regset and dump it.  The components also had to be careful to check
that they were actually registered in vc4 before dereferencing
themselves, in case they weren't probed on a particular platform.
They routinely failed at that.

Instead, we can have the components add their debugfs callbacks to a
little list in vc4 to be registered at drm_dev_register() time, which
gets vc4_debugfs.c out of the business of knowing the whole list of
components.

Thanks to this change, dsi0 (if it existed) would register its node.

v2: Rebase on hvs_underrun addition.
v3: whitespace fixup

drm_dev_register() initializes internal clients like bootsplash as the
last thing it does, so all setup needs to be done at this point.

Fix by calling vc4_kms_load() before registering.
Also check the error code returned from that function.

Laurent Pinchart 97eb9eaeb9 drm: writeback: Cleanup job ownership handling when queuing job
The drm_writeback_queue_job() function takes ownership of the passed job
and requires the caller to manually set the connector state
writeback_job pointer to NULL. To simplify drivers and avoid errors
(such as the missing NULL set in the vc4 driver), pass the connector
state pointer to the function instead of the job pointer, and set the
writeback_job pointer to NULL internally.

drm/vc4: Use 16bpp by default for the fbdev buffer
The preferred bpp for the fbdev emulation buffer has been 32 so far, which
means that by default we will allocate an 8MB buffer with a 1920x1080
resolution.

Worse this memory will be allocated from the CMA pool, and will never be
freed even if we don't use the fbdev emulation. Therefore, reducing it is a
big deal, and switching to 16bpp by default will gain us around 4MB at
1920x1080, while keeping decent color depth. And users still have the
option to switch to 32bpp using the kernel command line.

drm/vc4: Add a debugfs entry to disable/enable the load tracker
In order to test whether the load tracker is working as expected, we
need the ability to compare the commit result with the underrun
indication. With the load tracker always enabled, commits that are
expected to trigger an underrun are always rejected, so userspace
cannot get the actual underrun indication from the hardware.

Add a debugfs entry to disable/enable the load tracker, so that a DRM
commit expected to trigger an underrun can go through with the load
tracker disabled. The underrun indication is then available to
userspace and can be checked against the commit result with the load
tracker enabled.

drm/vc4: Add a load tracker to prevent HVS underflow errors
The HVS block is supposed to fill the pixelvalve FIFOs fast enough to
meet the requested framerate. The problem is, the HVS and memory bus
bandwidths are limited, and if we don't take these limitations into
account we might end up with HVS underflow errors.

This patch is trying to model the per-plane HVS and memory bus bandwidth
consumption and take a decision at atomic_check() time whether the
estimated load will fit in the HVS and membus budget.

Note that we take an extra margin on the memory bus consumption to let
the system run smoothly when other blocks are doing heavy use of the
memory bus. Same goes for the HVS limit, except the margin is smaller in
this case, since the HVS is not used by external components.

Gustavo A. R. Silva 1eb6ea4a82 drm/vc4: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

Daniel Vetter fcd70cd36b drm: Split out drm_probe_helper.h
Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

drm/vc4: Limit SAND tiling support to semiplanar YUV420 formats
Despite what the HVS documentation indicates, the VC4 does not actually
support SAND tiling modes for any RGB format and only semiplanar YUV420
formats (NV12/NV21) can be used in these tiling modes.

The driver currently claims to support RGB formats for the associated
modifiers, so remove them from the supported list in the
format_mod_supported helper for RGB formats.

Remove further checks that are no longer necessary along the way, since
semi-planar YUV420 formats support every SAND tiling mode.

vc4_plane_atomic_async_check() was only based on the
state->{crtc,src}_{w,h} which was fine since scaling was not allowed on

We are about to change that to properly support underscan, and, in order
to make the async check more reliable, we call vc4_plane_mode_set()
from there and check that only the pos0, pos2 and ptr0 entries in the
dlist have changed.

In vc4_plane_atomic_async_update(), we no longer call
vc4_plane_atomic_check() since vc4_plane_mode_set() has already been
called in vc4_plane_atomic_async_check(), and we don't need to allocate
a new LBM region (we reuse the one from the current state).

Note that we now have to manually update each field of the current
plane state since it's no longer updated in place (not sure we have
to sync all of them, but it's harmless if we do).
We also drop the vc4_plane_async_set_fb() call (ptr0 dlist entry has

recommendation.

Boris Brezillon 0560054da5 drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONE
For the YUV conversion to work properly, ->x_scaling[1] should never
be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return
VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the
horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE
into VC4_SCALING_PPF when that happens.

The old ->x_scaling[0] adjustment is dropped as I couldn't find any
mention to this constraint in the spec and it's proven to be
unnecessary (I tested various multi-planar YUV formats with scaling
disabled, and all of them worked fine without this adjustment).

Boris Brezillon 2b02a05bdc drm/vc4: Set ->is_yuv to false when num_planes == 1
When vc4_plane_state is duplicated ->is_yuv is left assigned to its
previous value, and we never set it back to false when switching to
a non-YUV format.

Fix that by setting ->is_yuv to false in the 'num_planes == 1' branch
of the vc4_plane_setup_clipping_and_scaling() function.

Boris Brezillon 3e407417b1 drm/vc4: Fix X/Y positioning of planes using T_TILES modifier
X/Y positioning of T-format buffers is quite tricky and the current
implementation was failing to position a plane using this format
correctly when the CRTC X, Y or both X and Y offsets were negative.
It was also failing when the SRC X/Y offsets were != 0.

Boris Brezillon a65511b1cd drm/vc4: Move ->offsets[] adjustment out of setup_clipping_and_scaling()
The offset adjustment depends on the framebuffer modified, so let's
just move this operation in the DRM_FORMAT_MOD_LINEAR case inside
vc4_plane_mode_set().

This we'll be able to fix offset calculation for
DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX.

Boris Brezillon 58a6a36fe8 drm/vc4: Use drm_atomic_helper_check_plane_state() to simplify the logic
drm_atomic_helper_check_plane_state() takes care of checking the
scaling capabilities and calculating the clipped X/Y offsets for us.

Rely on this function instead of open-coding the logic.

Incidentally, it seems to fix a problem we had with negative X/Y
positioning of YUV planes.
