We have a bunch of neat little macros all over the place which should
move to kernel.h. But some of them died in bikesheds on lkml, and we
need a decent home for them.
Start out by moving the for_each_if macro there.

Only needed minimal changes in drm_internal.h (for the drm_ioctl_t
type and a few forward declarations), plus a few missing includes in
drm_connector.c.
Yay, the last stage of the drm header cleanup can finally commence!
v2: Compiles now, with drm/kernel.h extracted.

Remove the kerneldoc and EXPORT_SYMBOL which aren't used and really
shouldn't ever be used by drivers directly.
Unfortunately this means we need to move the set_writeback_fb function
around to avoid a forward decl.

This leaves all the commit/check and state handling in drm_atomic.c,
while pulling all the uapi glue and the huge ioctl itself into a
seprate file.
This seems to almost perfectly split the rather big drm_atomic.c file
into 2 equal sizes.
Also adjust the kerneldoc and type a very terse overview text.
v2: Rebase.
v3: Fix tiny typo.

- * DOC: explicit fencing properties
- *
- * Explicit fencing allows userspace to control the buffer synchronization
- * between devices. A Fence or a group of fences are transfered to/from
- * userspace using Sync File fds and there are two DRM properties for that.
- * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
- * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
- *
- * As a contrast, with implicit fencing the kernel keeps track of any
- * ongoing rendering, and automatically ensures that the atomic update waits
- * for any pending rendering to complete. For shared buffers represented with
- * a &struct dma_buf this is tracked in &struct reservation_object.
- * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
- * whereas explicit fencing is what Android wants.
- *
- * "IN_FENCE_FD”:
- * Use this property to pass a fence that DRM should wait on before
- * proceeding with the Atomic Commit request and show the framebuffer for
- * the plane on the screen. The fence can be either a normal fence or a
- * merged one, the sync_file framework will handle both cases and use a
- * fence_array if a merged fence is received. Passing -1 here means no
- * fences to wait on.
- *
- * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
- * it will only check if the Sync File is a valid one.
- *
- * On the driver side the fence is stored on the @fence parameter of
- * &struct drm_plane_state. Drivers which also support implicit fencing
- * should set the implicit fence using drm_atomic_set_fence_for_plane(),
- * to make sure there's consistent behaviour between drivers in precedence
- * of implicit vs. explicit fencing.
- *
- * "OUT_FENCE_PTR”:
- * Use this property to pass a file descriptor pointer to DRM. Once the
- * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
- * the file descriptor number of a Sync File. This Sync File contains the
- * CRTC fence that will be signaled when all framebuffers present on the
- * Atomic Commit * request for that given CRTC are scanned out on the
- * screen.
- *
- * The Atomic Commit request fails if a invalid pointer is passed. If the
- * Atomic Commit request fails for any other reason the out fence fd
- * returned will be -1. On a Atomic Commit with the
- * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
- *
- * Note that out-fences don't have a special interface to drivers and are
- * internally represented by a &struct drm_pending_vblank_event in struct
- * &drm_crtc_state, which is also used by the nonblocking atomic commit
- * helpers and for the DRM event handling for existing userspace.

+/**
+ * DOC: explicit fencing properties
+ *
+ * Explicit fencing allows userspace to control the buffer synchronization
+ * between devices. A Fence or a group of fences are transfered to/from
+ * userspace using Sync File fds and there are two DRM properties for that.
+ * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
+ * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
+ *
+ * As a contrast, with implicit fencing the kernel keeps track of any
+ * ongoing rendering, and automatically ensures that the atomic update waits
+ * for any pending rendering to complete. For shared buffers represented with
+ * a &struct dma_buf this is tracked in &struct reservation_object.
+ * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
+ * whereas explicit fencing is what Android wants.
+ *
+ * "IN_FENCE_FD”:
+ * Use this property to pass a fence that DRM should wait on before
+ * proceeding with the Atomic Commit request and show the framebuffer for
+ * the plane on the screen. The fence can be either a normal fence or a
+ * merged one, the sync_file framework will handle both cases and use a
+ * fence_array if a merged fence is received. Passing -1 here means no
+ * fences to wait on.
+ *
+ * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
+ * it will only check if the Sync File is a valid one.
+ *
+ * On the driver side the fence is stored on the @fence parameter of
+ * &struct drm_plane_state. Drivers which also support implicit fencing
+ * should set the implicit fence using drm_atomic_set_fence_for_plane(),
+ * to make sure there's consistent behaviour between drivers in precedence
+ * of implicit vs. explicit fencing.
+ *
+ * "OUT_FENCE_PTR”:
+ * Use this property to pass a file descriptor pointer to DRM. Once the
+ * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
+ * the file descriptor number of a Sync File. This Sync File contains the
+ * CRTC fence that will be signaled when all framebuffers present on the
+ * Atomic Commit * request for that given CRTC are scanned out on the
+ * screen.
+ *
+ * The Atomic Commit request fails if a invalid pointer is passed. If the
+ * Atomic Commit request fails for any other reason the out fence fd
+ * returned will be -1. On a Atomic Commit with the
+ * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
+ *
+ * Note that out-fences don't have a special interface to drivers and are
+ * internally represented by a &struct drm_pending_vblank_event in struct
+ * &drm_crtc_state, which is also used by the nonblocking atomic commit
+ * helpers and for the DRM event handling for existing userspace.

It's the default. The exported version was kinda a transition state,
before we made this the default.
To stop new atomic drivers from using it (instead of just relying on
the default) let's unexport it.

For atomic driver this is the default, no need to reimplement it. We
still need to keep the copypasta for not-atomic drivers though, since
no one polished the legacy crtc helpers as much as the atomic ones.

- vkms is happening (and will gain its own todo and docs under a new
vkms.rst file real soon)
- legacy cruft is completely hidden now, drm_vblank.c is split out
from drm_irq.c now.
- best_encoder atomic cleanup is done (it's now the default, not even
exported anymore)
- bunch of smaller things

+/**
+ * DOC: atomic state reset and initialization
+ *
+ * Both the drm core and the atomic helpers assume that there is always the full
+ * and correct atomic software state for all connectors, CRTCs and planes
+ * available. Which is a bit a problem on driver load and also after system
+ * suspend. One way to solve this is to have a hardware state read-out
+ * infrastructure which reconstructs the full software state (e.g. the i915
+ * driver).
+ *
+ * The simpler solution is to just reset the software state to everything off,
+ * which is easiest to do by calling drm_mode_config_reset(). To facilitate this
+ * the atomic helpers provide default reset implementations for all hooks.
+ *
+ * On the upside the precise state tracking of atomic simplifies system suspend
+ * and resume a lot. For drivers using drm_mode_config_reset() a complete recipe
+ * is implemented in drm_atomic_helper_suspend() and drm_atomic_helper_resume().
+ * For other drivers the building blocks are split out, see the documentation
+ * for these functions.

The core _does_ the call to drm_atomic_commit for you. That's pretty
much the entire point of having the fancy new atomic_set/get_prop
callbacks.

That's purely for the uapi layer to implement the ALLOW_MODESET flag.
Drivers should instead look at the state, e.g. through
drm_atomic_crtc_needs_modeset(), which vmwgfx already does. Also remove
the confusing comment, since checking allow_modeset is at best a micro
optimization.

Motivated by vmwgfx digging around in core uapi bits it shouldn't dig
around in.

The idea behind allowing drivers to override legacy ioctls (instead of
using the generic implementations unconditionally) is to handle bugs
in old driver-specific userspace. Like e.g. vmw_kms_set_config does,
to work around some vmwgfx userspace not clearing its ioctl structs
properly.
But you can't use it to augment semantics and put in additional
checks, since from a correctly working userspace's pov there should
not be any difference in behaviour between the legacy and the atomic
paths.
vmwgfx seems to be doing some strange things in its page_flip
handlers. Since I'm not an expert of this codebase just wrap some
FIXME comments around the potentially problematic code.

Yup, but I kinda figured I'll give up on this idea. The code is hidden
well enough, I don't think a drm-legacy.ko will buy us much. Except lots
of churn on older driver's Kconfig entries for no purpose.
There's been a patch already a while back to hide the legacy drivers
better, and Dave nacked it. So I'm not really for pushing this idea
anymore as a good task for newbies (which todo.rst tries to collect).
Want me to explain this a bit better in the commit message?

Thanks for the patch, Daniel
Your comments seem valid. We'll try to fix this internally before the
next merge window rather than to add the FIXMEs

Sounds all good to me. And if you have questions I'm happy to help out
(and use that generally as an opportunity to improve the docs).

> - * DOC: explicit fencing properties
> - *
> - * Explicit fencing allows userspace to control the buffer synchronization
> - * between devices. A Fence or a group of fences are transfered to/from
> - * userspace using Sync File fds and there are two DRM properties for that.
> - * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
> - * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
> - *
> - * As a contrast, with implicit fencing the kernel keeps track of any
> - * ongoing rendering, and automatically ensures that the atomic update waits
> - * for any pending rendering to complete. For shared buffers represented with
> - * a &struct dma_buf this is tracked in &struct reservation_object.
> - * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
> - * whereas explicit fencing is what Android wants.
> - *
> - * "IN_FENCE_FD”:
> - * Use this property to pass a fence that DRM should wait on before
> - * proceeding with the Atomic Commit request and show the framebuffer for
> - * the plane on the screen. The fence can be either a normal fence or a
> - * merged one, the sync_file framework will handle both cases and use a
> - * fence_array if a merged fence is received. Passing -1 here means no
> - * fences to wait on.
> - *
> - * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
> - * it will only check if the Sync File is a valid one.
> - *
> - * On the driver side the fence is stored on the @fence parameter of
> - * &struct drm_plane_state. Drivers which also support implicit fencing
> - * should set the implicit fence using drm_atomic_set_fence_for_plane(),
> - * to make sure there's consistent behaviour between drivers in precedence
> - * of implicit vs. explicit fencing.
> - *
> - * "OUT_FENCE_PTR”:
> - * Use this property to pass a file descriptor pointer to DRM. Once the
> - * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
> - * the file descriptor number of a Sync File. This Sync File contains the
> - * CRTC fence that will be signaled when all framebuffers present on the
> - * Atomic Commit * request for that given CRTC are scanned out on the
> - * screen.
> - *
> - * The Atomic Commit request fails if a invalid pointer is passed. If the
> - * Atomic Commit request fails for any other reason the out fence fd
> - * returned will be -1. On a Atomic Commit with the
> - * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
> - *
> - * Note that out-fences don't have a special interface to drivers and are
> - * internally represented by a &struct drm_pending_vblank_event in struct
> - * &drm_crtc_state, which is also used by the nonblocking atomic commit
> - * helpers and for the DRM event handling for existing userspace.

> + * DOC: explicit fencing properties
> + *
> + * Explicit fencing allows userspace to control the buffer synchronization
> + * between devices. A Fence or a group of fences are transfered to/from
> + * userspace using Sync File fds and there are two DRM properties for that.
> + * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
> + * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
> + *
> + * As a contrast, with implicit fencing the kernel keeps track of any
> + * ongoing rendering, and automatically ensures that the atomic update waits
> + * for any pending rendering to complete. For shared buffers represented with
> + * a &struct dma_buf this is tracked in &struct reservation_object.
> + * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
> + * whereas explicit fencing is what Android wants.
> + *
> + * "IN_FENCE_FD”:
> + * Use this property to pass a fence that DRM should wait on before
> + * proceeding with the Atomic Commit request and show the framebuffer for
> + * the plane on the screen. The fence can be either a normal fence or a
> + * merged one, the sync_file framework will handle both cases and use a
> + * fence_array if a merged fence is received. Passing -1 here means no
> + * fences to wait on.
> + *
> + * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
> + * it will only check if the Sync File is a valid one.
> + *
> + * On the driver side the fence is stored on the @fence parameter of
> + * &struct drm_plane_state. Drivers which also support implicit fencing
> + * should set the implicit fence using drm_atomic_set_fence_for_plane(),
> + * to make sure there's consistent behaviour between drivers in precedence
> + * of implicit vs. explicit fencing.
> + *
> + * "OUT_FENCE_PTR”:
> + * Use this property to pass a file descriptor pointer to DRM. Once the
> + * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
> + * the file descriptor number of a Sync File. This Sync File contains the
> + * CRTC fence that will be signaled when all framebuffers present on the
> + * Atomic Commit * request for that given CRTC are scanned out on the
> + * screen.
> + *
> + * The Atomic Commit request fails if a invalid pointer is passed. If the
> + * Atomic Commit request fails for any other reason the out fence fd
> + * returned will be -1. On a Atomic Commit with the
> + * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
> + *
> + * Note that out-fences don't have a special interface to drivers and are
> + * internally represented by a &struct drm_pending_vblank_event in struct
> + * &drm_crtc_state, which is also used by the nonblocking atomic commit
> + * helpers and for the DRM event handling for existing userspace.

> > + * DOC: explicit fencing properties
> > + *
> > + * Explicit fencing allows userspace to control the buffer synchronization
> > + * between devices. A Fence or a group of fences are transfered to/from
> > + * userspace using Sync File fds and there are two DRM properties for that.
> > + * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
> > + * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
> > + *
> > + * As a contrast, with implicit fencing the kernel keeps track of any
> > + * ongoing rendering, and automatically ensures that the atomic update waits
> > + * for any pending rendering to complete. For shared buffers represented with
> > + * a &struct dma_buf this is tracked in &struct reservation_object.
> > + * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
> > + * whereas explicit fencing is what Android wants.
> > + *
> > + * "IN_FENCE_FD”:
> > + * Use this property to pass a fence that DRM should wait on before
> > + * proceeding with the Atomic Commit request and show the framebuffer for
> > + * the plane on the screen. The fence can be either a normal fence or a
> > + * merged one, the sync_file framework will handle both cases and use a
> > + * fence_array if a merged fence is received. Passing -1 here means no
> > + * fences to wait on.
> > + *
> > + * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
> > + * it will only check if the Sync File is a valid one.
> > + *
> > + * On the driver side the fence is stored on the @fence parameter of
> > + * &struct drm_plane_state. Drivers which also support implicit fencing
> > + * should set the implicit fence using drm_atomic_set_fence_for_plane(),
> > + * to make sure there's consistent behaviour between drivers in precedence
> > + * of implicit vs. explicit fencing.
> > + *
> > + * "OUT_FENCE_PTR”:
> > + * Use this property to pass a file descriptor pointer to DRM. Once the
> > + * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
> > + * the file descriptor number of a Sync File. This Sync File contains the
> > + * CRTC fence that will be signaled when all framebuffers present on the
> > + * Atomic Commit * request for that given CRTC are scanned out on the
> > + * screen.
> > + *
> > + * The Atomic Commit request fails if a invalid pointer is passed. If the
> > + * Atomic Commit request fails for any other reason the out fence fd
> > + * returned will be -1. On a Atomic Commit with the
> > + * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
> > + *
> > + * Note that out-fences don't have a special interface to drivers and are
> > + * internally represented by a &struct drm_pending_vblank_event in struct
> > + * &drm_crtc_state, which is also used by the nonblocking atomic commit
> > + * helpers and for the DRM event handling for existing userspace.

This leaves all the commit/check and state handling in drm_atomic.c,
while pulling all the uapi glue and the huge ioctl itself into a
seprate file.
This seems to almost perfectly split the rather big drm_atomic.c file
into 2 equal sizes.
Also adjust the kerneldoc and type a very terse overview text.
v2: Rebase.
v3: Fix tiny typo.
v4:
- Fixup armada, newly converted atomic driver hooray!
- Fixup msm/dpu1, newly added too.

-/**
- * DOC: explicit fencing properties
- *
- * Explicit fencing allows userspace to control the buffer synchronization
- * between devices. A Fence or a group of fences are transfered to/from
- * userspace using Sync File fds and there are two DRM properties for that.
- * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
- * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
- *
- * As a contrast, with implicit fencing the kernel keeps track of any
- * ongoing rendering, and automatically ensures that the atomic update waits
- * for any pending rendering to complete. For shared buffers represented with
- * a &struct dma_buf this is tracked in &struct reservation_object.
- * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
- * whereas explicit fencing is what Android wants.
- *
- * "IN_FENCE_FD”:
- * Use this property to pass a fence that DRM should wait on before
- * proceeding with the Atomic Commit request and show the framebuffer for
- * the plane on the screen. The fence can be either a normal fence or a
- * merged one, the sync_file framework will handle both cases and use a
- * fence_array if a merged fence is received. Passing -1 here means no
- * fences to wait on.
- *
- * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
- * it will only check if the Sync File is a valid one.
- *
- * On the driver side the fence is stored on the @fence parameter of
- * &struct drm_plane_state. Drivers which also support implicit fencing
- * should set the implicit fence using drm_atomic_set_fence_for_plane(),
- * to make sure there's consistent behaviour between drivers in precedence
- * of implicit vs. explicit fencing.
- *
- * "OUT_FENCE_PTR”:
- * Use this property to pass a file descriptor pointer to DRM. Once the
- * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
- * the file descriptor number of a Sync File. This Sync File contains the
- * CRTC fence that will be signaled when all framebuffers present on the
- * Atomic Commit * request for that given CRTC are scanned out on the
- * screen.
- *
- * The Atomic Commit request fails if a invalid pointer is passed. If the
- * Atomic Commit request fails for any other reason the out fence fd
- * returned will be -1. On a Atomic Commit with the
- * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
- *
- * Note that out-fences don't have a special interface to drivers and are
- * internally represented by a &struct drm_pending_vblank_event in struct
- * &drm_crtc_state, which is also used by the nonblocking atomic commit
- * helpers and for the DRM event handling for existing userspace.

+/**
+ * DOC: explicit fencing properties
+ *
+ * Explicit fencing allows userspace to control the buffer synchronization
+ * between devices. A Fence or a group of fences are transfered to/from
+ * userspace using Sync File fds and there are two DRM properties for that.
+ * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
+ * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
+ *
+ * As a contrast, with implicit fencing the kernel keeps track of any
+ * ongoing rendering, and automatically ensures that the atomic update waits
+ * for any pending rendering to complete. For shared buffers represented with
+ * a &struct dma_buf this is tracked in &struct reservation_object.
+ * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
+ * whereas explicit fencing is what Android wants.
+ *
+ * "IN_FENCE_FD”:
+ * Use this property to pass a fence that DRM should wait on before
+ * proceeding with the Atomic Commit request and show the framebuffer for
+ * the plane on the screen. The fence can be either a normal fence or a
+ * merged one, the sync_file framework will handle both cases and use a
+ * fence_array if a merged fence is received. Passing -1 here means no
+ * fences to wait on.
+ *
+ * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
+ * it will only check if the Sync File is a valid one.
+ *
+ * On the driver side the fence is stored on the @fence parameter of
+ * &struct drm_plane_state. Drivers which also support implicit fencing
+ * should set the implicit fence using drm_atomic_set_fence_for_plane(),
+ * to make sure there's consistent behaviour between drivers in precedence
+ * of implicit vs. explicit fencing.
+ *
+ * "OUT_FENCE_PTR”:
+ * Use this property to pass a file descriptor pointer to DRM. Once the
+ * Atomic Commit request call returns OUT_FENCE_PTR will be filled with
+ * the file descriptor number of a Sync File. This Sync File contains the
+ * CRTC fence that will be signaled when all framebuffers present on the
+ * Atomic Commit * request for that given CRTC are scanned out on the
+ * screen.
+ *
+ * The Atomic Commit request fails if a invalid pointer is passed. If the
+ * Atomic Commit request fails for any other reason the out fence fd
+ * returned will be -1. On a Atomic Commit with the
+ * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
+ *
+ * Note that out-fences don't have a special interface to drivers and are
+ * internally represented by a &struct drm_pending_vblank_event in struct
+ * &drm_crtc_state, which is also used by the nonblocking atomic commit
+ * helpers and for the DRM event handling for existing userspace.

- drmP.h is now fully split up.
- vkms is happening (and will gain its own todo and docs under a new
vkms.rst file real soon)
- legacy cruft is completely hidden now, drm_vblank.c is split out
from drm_irq.c now. I've decided to drop the task to split out
drm_legacy.ko, partially because Dave already rejected a patch to
hide the old dri1 drivers better. Current state feels good enough to
me.
- best_encoder atomic cleanup is done (it's now the default, not even
exported anymore)
- bunch of smaller things
v2:
- Explain why the drm_legacy.ko task is dropped (Emil).
- typos (Sam).

-Way back DRM supported only drivers which shadow-attached to PCI devices with

-Unfortunately there's still large piles of legacy code around which needs to
-be hidden so that driver writers don't accidentally end up using it. And to
-prevent security issues in those legacy IOCTLs from being exploited on modern
-drivers. This has multiple possible subtasks:
-
-* Extract support code for legacy features into a ``drm-legacy.ko`` kernel
- module and compile it only when one of the legacy drivers is enabled.

-This is mostly done, the only thing left is to split up ``drm_irq.c`` into

Thanks for the patch! It seems I made an identical change here:
https://lists.freedesktop.org/archives/amd-gfx/2018-August/026064.html
One line difference though. I wasn't aware that the default is used when
.best_encoder is null, so I just hooked it to the default helper.
If it's OK with you, I'll do a follow-up to drop the hook, so we don't
have two conflicting patches in flight.

I have a follow-up patches to unexport the helper, so would be good if
Alex sends out the pull request so I can sort this all out in
drm-misc-next. I don't want to split up the patch series if possible.
Or we just deal with the conflict, it's minor.

I'm planning to send the PR next week when I'm back in the office. I can drop Leo's patch when I send the PR if that makes things easier.

I'm happy to rebase, just go ahead. I've added a bunch more patches to
my helper cleanup series anyway, so will take a bit longer to get all
landed.
