[PATCH 0/2] drm/i915/gem: conversion to new drm logging macros

[Wambui Karuga]

This series is a part of the conversion to  the new struct drm_device
based logging macros in drm/i915.
This series focuses on the drm/i915/gem directory and converts all
straightforward instances of the printk based logging macros to the new
macros.

  drm/i915/gem: initial conversion to new logging macros using
    coccinelle.
  drm/i915/gem: manual conversion to struct drm_device logging macros.

[PATCH 1/2] drm/i915/gem: initial conversion to new logging macros using coccinelle

[Wambui Karuga]

First pass of conversion to the new struct drm_based device logging
macros in the drm/i915/gem directory. This conversion was achieved using
the following coccinelle script that transforms based on the existence
of a straightforward struct drm_i915_private device:

[PATCH 2/2] drm/i915/gem: manual conversion to struct drm_device logging macros.

[Wambui Karuga]

Convert most of the remaining uses of the printk based logging macros to
the new struct drm_device based logging macros in drm/i915/gem.
This also involves extracting the struct drm_i915_private device
from various types, and using it in the various macros.

Overall, I'm not keen on this as it perpetuates the mistake of putting
client debug message in dmesg and now gives them even more an air of
being device driver debug messages. We need a mechanism by which we
report the details of what a client did wrong back to that client
(tracefs + context/client getparam to return an isolated debug fd is my
idea).

Sean is working on that, but it's a global thing still. Well since it's
tracefs should be easy to filter for a given process at least. We've had
long discussion about how to expose that, big fear (especially with
atomic) is that clients/compositors will start to look at random debug
strings and make them uapi.

But I think for stuff like igt we should be able to wire it up easily and
get it dumped when things go wrong. Maybe similar when mesa gets an
unexpected errno.

Go look at how I suggest we can use tracefs in that thread :)

Hm I think we're a few threads further already? Steven Rostedt has jumped

I don't disagree, but I also don't think this makes things (much) worse
in that regard.

This changes DRM_UT_CORE to DRM_UT_DRIVER so our typical drm.debug=0xe 
becomes much more spammy.
