[Nouveau] [PATCH v2 00/20] drm: Use new DRM printk funcs (like drm_dbg_*()) in DP helpers

[Lyude Paul]

Since it's been asked quite a few times on some of the various DP
related patch series I've submitted to use the new DRM printk helpers,
and it technically wasn't really trivial to do this before due to the
lack of a consistent way to find a drm_device for an AUX channel, this
patch series aims to address this. In this series we:

* Clean-up potentially erroneous usages of drm_dp_aux_init() and
  drm_dp_aux_register() so that actual AUX registration doesn't happen
  until we have an associated DRM device
* Clean-up any obvious errors in drivers we find along the way
* Add a backpointer to the respective drm_device for an AUX channel in
  drm_dp_aux.drm_dev, and hook it up in every driver with an AUX channel
  across the tree
* Add a new ratelimited print helper we'll need for converting the DP
  helpers over to using the new DRM printk helpers
* Fix any inconsistencies with logging in drm_dp_helper.c so we always
  have the aux channel name printed
* Prepare the various DP helpers so they can find the correct drm_device
  to use for logging
* And finally, convert all of the DP helpers over to using drm_dbg_*()
  and drm_err().

Series-wide changes in v2:
* Address most checkpatch issues ('most' as in all except for one line
  going two chars over 100 in "drm/dp_mst: Pass drm_dp_mst_topology_mgr
  to drm_dp_get_vc_payload_bw()" as this was the style in use
  previously, and 2 chars over the limit looks nicer then trying to
  line-wrap this
* Don't rewrap comments

[PATCH v2 01/20] drm/dp: Fixup kernel docs for struct drm_dp_aux

[Lyude Paul]

* Make sure that struct members are referred to using @, otherwise they
  won't be formatted as such
* Make sure to refer to other struct types using & so they link back to
  each struct's definition
* Make sure to precede constant values with % so they're formatted
  correctly

[PATCH v2 02/20] drm/tegra: Don't register DP AUX channels before connectors

[Lyude Paul]

As pointed out by the documentation for drm_dp_aux_register(),
drm_dp_aux_init() should be used in situations where the AUX channel for a
display driver can potentially be registered before it's respective DRM
driver. This is the case with Tegra, since the DP aux channel exists as a
platform device instead of being a grandchild of the DRM device.

Since we're about to add a backpointer to a DP AUX channel's respective DRM
device, let's fix this so that we don't potentially allow userspace to use
the AUX channel before we've associated it with it's DRM connector.

[PATCH v2 02/20] drm/tegra: Don't register DP AUX channels before connectors

[Lyude Paul]

As pointed out by the documentation for drm_dp_aux_register(),
drm_dp_aux_init() should be used in situations where the AUX channel for a
display driver can potentially be registered before it's respective DRM
driver. This is the case with Tegra, since the DP aux channel exists as a
platform device instead of being a grandchild of the DRM device.

Since we're about to add a backpointer to a DP AUX channel's respective DRM
device, let's fix this so that we don't potentially allow userspace to use
the AUX channel before we've associated it with it's DRM connector.

[PATCH v2 04/20] drm/nouveau/kms/nv50-: Move AUX adapter reg to connector late register/early unregister

[Lyude Paul]

Since AUX adapters on nouveau have their respective DRM connectors as
parents, we need to make sure that we register then after their connectors.

[PATCH v2 05/20] drm/dp: Add backpointer to drm_device in drm_dp_aux

[Lyude Paul]

This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

[Nouveau] [PATCH v2 05/20] drm/dp: Add backpointer to drm_device in drm_dp_aux

[Lyude Paul]

This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

[Intel-gfx] [PATCH v2 05/20] drm/dp: Add backpointer to drm_device in drm_dp_aux

[Lyude Paul]

This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

[PATCH v2 05/20] drm/dp: Add backpointer to drm_device in drm_dp_aux

[Lyude Paul]

This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

[PATCH v2 06/20] drm/dp: Clarify DP AUX registration time

[Lyude Paul]

The docs we had for drm_dp_aux_init() and drm_dp_aux_register() were mostly
correct, except for the fact that they made the assumption that all AUX
devices were grandchildren of their respective DRM devices. This is the
case for most normal GPUs, but is almost never the case with SoCs and
display bridges. So, let's fix this documentation to clarify when the right
time to use drm_dp_aux_init() or drm_dp_aux_register() is.

The docs we had for drm_dp_aux_init() and drm_dp_aux_register() were mostly
correct, except for the fact that they made the assumption that all AUX
devices were grandchildren of their respective DRM devices. This is the
case for most normal GPUs, but is almost never the case with SoCs and
display bridges. So, let's fix this documentation to clarify when the right
time to use drm_dp_aux_init() or drm_dp_aux_register() is.

[PATCH v2 07/20] drm/print: Fixup DRM_DEBUG_KMS_RATELIMITED()

[Lyude Paul]

Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want
to make sure that we can also add ratelimited versions of these macros in
order to retain some of the previous debugging output behavior we had.

However, as I was preparing to do this I noticed that the current
rate limited macros we have are kind of bogus. It looks like when I wrote
these, I didn't notice that we'd always be calling __ratelimit() even if
the debugging message we'd be printing would normally be filtered out due
to the relevant DRM debugging category being disabled.

So, let's fix this by making sure to check drm_debug_enabled() in our
ratelimited macros before calling __ratelimit(), and start using
drm_dev_printk() in order to print debugging messages since that will save
us from doing a redundant drm_debug_enabled() check. And while we're at it,
let's move the code for this into another macro that we can reuse for
defining new ratelimited DRM debug macros more easily.

* Make sure to use tabs where possible in __DRM_DEFINE_DBG_RATELIMITED()

[PATCH v2 09/20] drm/dp: Pass drm_dp_aux to drm_dp*_link_train_channel_eq_delay()

[Lyude Paul]

So that we can start using drm_dbg_*() for
drm_dp_link_train_channel_eq_delay() and
drm_dp_lttpr_link_train_channel_eq_delay().

[Intel-gfx] [PATCH v2 09/20] drm/dp: Pass drm_dp_aux to drm_dp*_link_train_channel_eq_delay()

[Lyude Paul]

So that we can start using drm_dbg_*() for
drm_dp_link_train_channel_eq_delay() and
drm_dp_lttpr_link_train_channel_eq_delay().

[PATCH v2 11/20] drm/dp_dual_mode: Pass drm_device to drm_dp_dual_mode_detect()

[Lyude Paul]

Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll
need to be able to access the DRM device in the dual mode DP helpers as
well. Note however that since drm_dp_dual_mode_detect() can be called with
DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down
the drm_device to these functions instead of using drm_dp_aux.

[PATCH v2 11/20] drm/dp_dual_mode: Pass drm_device to drm_dp_dual_mode_detect()

[Lyude Paul]

Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll
need to be able to access the DRM device in the dual mode DP helpers as
well. Note however that since drm_dp_dual_mode_detect() can be called with
DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down
the drm_device to these functions instead of using drm_dp_aux.

[Nouveau] [PATCH v2 12/20] drm/dp_dual_mode: Pass drm_device to drm_dp_dual_mode_set_tmds_output()

[Lyude Paul]

Another function that we'll need to pass a drm_device (and not drm_dp_aux)
down to so that we can move over to using drm_dbg_*().

[PATCH v2 14/20] drm/dp_dual_mode: Pass drm_device to drm_dp_dual_mode_get_tmds_output()

[Lyude Paul]

Another function to pass drm_device * down to so we can start using the
drm_dbg_*() in the DRM DP helpers.

[Intel-gfx] [PATCH v2 16/20] drm/dp_mst: Pass drm_dp_mst_topology_mgr to drm_dp_get_vc_payload_bw()

[Lyude Paul]

Since this is one of the few functions in drm_dp_mst_topology.c that
doesn't have any way of getting access to a drm_device, let's pass the
drm_dp_mst_topology_mgr down to this function so that it can use
drm_dbg_kms().

[PATCH v2 17/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

[Lyude Paul]

Now that we've added a back-pointer to drm_device to drm_dp_aux, made
drm_dp_aux available to any functions in drm_dp_helper.c which need to
print to the kernel log, and ensured all of our logging uses a consistent
format, let's do the final step of the conversion and actually move
everything over to using drm_err() and drm_dbg_*().

This was done by using the following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(aux->drm_dev, expr);
  |
  - DRM_DEBUG_DP(expr);
  + drm_dbg_dp(aux->drm_dev, expr);
  |
  - DRM_DEBUG_ATOMIC(expr);
  + drm_dbg_atomic(aux->drm_dev, expr);
  |
  - DRM_DEBUG_KMS_RATELIMITED(expr);
  + drm_dbg_kms_ratelimited(aux->drm_dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(aux->drm_dev, expr);
  )

Followed by correcting the resulting line-wrapping in the results by hand.

v2:
* Fix indenting in drm_dp_dump_access

[Nouveau] [PATCH v2 17/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

[Lyude Paul]

Now that we've added a back-pointer to drm_device to drm_dp_aux, made
drm_dp_aux available to any functions in drm_dp_helper.c which need to
print to the kernel log, and ensured all of our logging uses a consistent
format, let's do the final step of the conversion and actually move
everything over to using drm_err() and drm_dbg_*().

This was done by using the following cocci script:

  @@
  expression list expr;

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(aux->drm_dev, expr);
  |

  + drm_dbg_kms_ratelimited(aux->drm_dev, expr);

  - DRM_ERROR(expr);
  + drm_err(aux->drm_dev, expr);
  )

Followed by correcting the resulting line-wrapping in the results by hand.

[Intel-gfx] [PATCH v2 17/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

[Lyude Paul]

Now that we've added a back-pointer to drm_device to drm_dp_aux, made
drm_dp_aux available to any functions in drm_dp_helper.c which need to
print to the kernel log, and ensured all of our logging uses a consistent
format, let's do the final step of the conversion and actually move
everything over to using drm_err() and drm_dbg_*().

This was done by using the following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(aux->drm_dev, expr);
  |
  - DRM_DEBUG_DP(expr);
  + drm_dbg_dp(aux->drm_dev, expr);
  |
  - DRM_DEBUG_ATOMIC(expr);
  + drm_dbg_atomic(aux->drm_dev, expr);
  |
  - DRM_DEBUG_KMS_RATELIMITED(expr);
  + drm_dbg_kms_ratelimited(aux->drm_dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(aux->drm_dev, expr);
  )

Followed by correcting the resulting line-wrapping in the results by hand.

v2:
* Fix indenting in drm_dp_dump_access

[PATCH v2 17/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

[Lyude Paul]

Now that we've added a back-pointer to drm_device to drm_dp_aux, made
drm_dp_aux available to any functions in drm_dp_helper.c which need to
print to the kernel log, and ensured all of our logging uses a consistent
format, let's do the final step of the conversion and actually move
everything over to using drm_err() and drm_dbg_*().

This was done by using the following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(aux->drm_dev, expr);
  |
  - DRM_DEBUG_DP(expr);
  + drm_dbg_dp(aux->drm_dev, expr);
  |
  - DRM_DEBUG_ATOMIC(expr);
  + drm_dbg_atomic(aux->drm_dev, expr);
  |
  - DRM_DEBUG_KMS_RATELIMITED(expr);
  + drm_dbg_kms_ratelimited(aux->drm_dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(aux->drm_dev, expr);
  )

Followed by correcting the resulting line-wrapping in the results by hand.

v2:
* Fix indenting in drm_dp_dump_access

[PATCH v2 18/20] drm/dp_dual_mode: Convert drm_dp_dual_mode_helper.c to using drm_err/drm_dbg_kms()

[Lyude Paul]

Next step in the conversion, move everything in drm_dp_dual_mode_helper.c
over to using drm_err() and drm_dbg_kms(). This was done using the
following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(dev, expr);
  )

And correcting the indentation of the resulting code by hand.

[Intel-gfx] [PATCH v2 18/20] drm/dp_dual_mode: Convert drm_dp_dual_mode_helper.c to using drm_err/drm_dbg_kms()

[Lyude Paul]

Next step in the conversion, move everything in drm_dp_dual_mode_helper.c
over to using drm_err() and drm_dbg_kms(). This was done using the
following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(dev, expr);
  )

And correcting the indentation of the resulting code by hand.

[PATCH v2 19/20] drm/dp_mst: Drop DRM_ERROR() on kzalloc() fail in drm_dp_mst_handle_up_req()

[Lyude Paul]

Checkpatch was complaining about this - there's no need for us to print
errors when kzalloc() fails, as kzalloc() will already WARN for us. So,
let's fix that before converting things to make checkpatch happy.

[PATCH v2 19/20] drm/dp_mst: Drop DRM_ERROR() on kzalloc() fail in drm_dp_mst_handle_up_req()

[Lyude Paul]

Checkpatch was complaining about this - there's no need for us to print
errors when kzalloc() fails, as kzalloc() will already WARN for us. So,
let's fix that before converting things to make checkpatch happy.

[PATCH v2 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

[Lyude Paul]

And finally, convert all of the code in drm_dp_mst_topology.c over to using
drm_err() and drm_dbg*(). Note that this refactor would have been a lot
more complicated to have tried writing a coccinelle script for, so this
whole thing was done by hand.

v2:
* Fix line-wrapping in drm_dp_mst_atomic_check_mstb_bw_limit()

[Nouveau] [PATCH v2 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

[Lyude Paul]

And finally, convert all of the code in drm_dp_mst_topology.c over to using
drm_err() and drm_dbg*(). Note that this refactor would have been a lot
more complicated to have tried writing a coccinelle script for, so this
whole thing was done by hand.

v2:
* Fix line-wrapping in drm_dp_mst_atomic_check_mstb_bw_limit()

[PATCH v2 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

[Lyude Paul]

And finally, convert all of the code in drm_dp_mst_topology.c over to using
drm_err() and drm_dbg*(). Note that this refactor would have been a lot
more complicated to have tried writing a coccinelle script for, so this
whole thing was done by hand.

v2:
* Fix line-wrapping in drm_dp_mst_atomic_check_mstb_bw_limit()

[Intel-gfx] [PATCH v2 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

[Lyude Paul]

And finally, convert all of the code in drm_dp_mst_topology.c over to using
drm_err() and drm_dbg*(). Note that this refactor would have been a lot
more complicated to have tried writing a coccinelle script for, so this
whole thing was done by hand.

v2:
* Fix line-wrapping in drm_dp_mst_atomic_check_mstb_bw_limit()

[PATCH v2 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

[Lyude Paul]

And finally, convert all of the code in drm_dp_mst_topology.c over to using
drm_err() and drm_dbg*(). Note that this refactor would have been a lot
more complicated to have tried writing a coccinelle script for, so this
whole thing was done by hand.

v2:
* Fix line-wrapping in drm_dp_mst_atomic_check_mstb_bw_limit()

Hey Lyude,

This patch looks good, but I have one question below. With it
addressed, feel free to add my r-b.

drm_dp_sideband_parse_req() is only called here, and the function
arguments could probably stand to have `&mgr->up_req_recv` removed
(here and in the func. declaration) since the same data structure is
accessible through the `mgr` pointer inside of
drm_dp_sideband_parse_req(). I guess this is a matter of taste, so
feel free to do what you want with this.

For anything touching i915, and for merging via whichever tree or branch
seems best,

That said, gut feeling says there will be conflicts before latest
drm-misc-next and drm-intel-next have been merged to drm-next, and
drm-next has been backmerged to drm-misc-next and drm-intel-next.

It just might be a good idea to wait for those (as well as other driver
feature pulls) to settle, do a topic branch with a common ancestor
between drm-next and drm-misc-next, apply there, merge the topic branch
to drm-misc-next, and let all drivers merge the topic branch as
needed. Due to the timing, otherwise we might have to carry the
conflicts for quite a while.

Jani.

For anything touching i915, and for merging via whichever tree or branch
seems best,

Acked-by: Jani Nikula <jani.nikula@intel.com>

That said, gut feeling says there will be conflicts before latest
drm-misc-next and drm-intel-next have been merged to drm-next, and
drm-next has been backmerged to drm-misc-next and drm-intel-next.

It just might be a good idea to wait for those (as well as other driver
feature pulls) to settle, do a topic branch with a common ancestor
between drm-next and drm-misc-next, apply there, merge the topic branch
to drm-misc-next, and let all drivers merge the topic branch as
needed. Due to the timing, otherwise we might have to carry the
conflicts for quite a while.

BR,
Jani.

I think Dave caught up on pulls to drm-next, so after a backmerge of that
to drm-misc-next I think should be all fine to apply directly, no need for
topic branch.

I think Dave caught up on pulls to drm-next, so after a backmerge of that
to drm-misc-next I think should be all fine to apply directly, no need for
topic branch.

Yup. We've done the backmerges to drm-intel-next and drm-intel-gt-next,
and are all in sync, it's only the drm-next -> drm-misc-next backmerge
that's still needed.

JFYI too - there was a legitimate looking CI failure on intel with this series,
so don't be surprised if I have to respin a patch or two (I should be able to
get it asap as I finally just cleared most of the stuff on my plate off for a
while)

Re: [Intel-gfx] [PATCH v2 00/20] drm: Use new DRM printk funcs (like drm_dbg_*()) in DP helpers

[Lyude Paul]

JFYI too - there was a legitimate looking CI failure on intel with this series,
so don't be surprised if I have to respin a patch or two (I should be able to
get it asap as I finally just cleared most of the stuff on my plate off for a
while)
