upgrade the callchain to drm_dbg() and drm_dev_dbg(); add a struct
_ddebug ptr parameter to them, and supply that additional param by
replacing the '_no_desc' flavor of dyndbg Factory macro currently used
with the flavor that supplies the descriptor.
NOTES:
The descriptor gives these fns access to the decorator flags, but they
do none of the dynamic-prefixing done by dynamic_emit_prefix(), which
is currently static.
DRM already has conventions for logging/messaging; just tossing
optional decorations on top probably wouldn't help. Instead, existing
flags (or new ones, perhaps 'sd' ala lspci) can be used to make
current message conventions optional. This suggests a new
drmdbg_prefix_emit() to handle prefixing locally.
For CONFIG_DRM_USE_DYNAMIC_DEBUG=N, just pass null descriptor.
desc->class_id is redundant with category parameter, but its
availability is dependent on desc.

When CONFIG_DRM_USE_DYNAMIC_DEBUG=y, the drm.debug API (a macro stack,
calling _+drm_*dbg() eventually) invokes a dyndbg Factory macro to
create a descriptor for each callsite, thus making them individually
>control-able.
In this case, the calls to _drm_*dbg are unreachable unless the
callsite is enabled. So those calls can short-circuit their early
do-nothing returns. Provide and use __drm_debug_enabled(), to do this
when config'd, or the _raw flags-check otherwize.
And since dyndbg is in use, lets also instrument the remaining users
of drm_debug_enabled, by wrapping the _raw in a macro with a:
pr_debug("todo: is this frequent enough to optimize ?\n");
For CONFIG_DRM_USE_DYNAMIC_DEBUG=n, do no site instrumenting at all,
since JUMP_LABEL might be off, and we don't want to make work.
With drm, amdgpu, i915, nouveau loaded, heres remaining uses of
drm_debug_enabled(), which costs ~1.5kb data to control the
pr_debug("todo:..")s.
Some of those uses might be ok to use __drm_debug_enabled() by
inspection, others might warrant conversion to use dyndbg Factory
macros, and that would want callrate data to estimate the savings
possible. TBH, any remaining savings are probably small; drm.debug
covers the vast bulk of the uses. Maybe "vblank" is the exception.

drm_print defines all of these:
drm_dbg_{core,kms,prime,atomic,vbl,lease,_dp,_drmres}
but not drm_dbg_driver itself, since it was the original drm_dbg.
To improve namespace symmetry, change the drm_dbg defn to
drm_dbg_driver, and redef grandfathered name to symmetric one.
This will help with nouveau, which uses its own stack of macros to
construct calls to dev_info, dev_dbg, etc, for which adaptation means
drm_dbg_##driver constructs.

Since that macro is defined in drm_print.h, and under DRM_USE_DYN*=y
configs, invokes dyndbg-factory macros, include dynamic_debug.h from
there too, so that those configs have the definitions of all the

For CONFIG_DRM_USE_DYNAMIC_DEBUG=y, wrap __drm_dbg() & __drm_dev_dbg()
in one of dyndbg's Factory macros: _dynamic_func_call_no_desc().
This adds the callsite descriptor into the code, and an entry for each
into /proc/dynamic_debug/control.
#> echo class DRM_UT_ATOMIC +p > /proc/dynamic_debug/control
CONFIG_DRM_USE_DYNAMIC_DEBUG=y/n is configurable because of the .data
footprint cost of per-callsite control; 56 bytes/site * ~2k for i915,
~4k callsites for amdgpu. This is large enough that a kernel builder
might not want it.

change drm_dev_dbg & drm_dbg to macros, which forward to the renamed
functions (with __ prefix added).
Those functions sit below the categorized layer of macros implementing
the DRM debug.category API, and implement most of it. These are good
places to insert dynamic-debug jump-label mechanics, which will allow
DRM to avoid the runtime cost of drm_debug_enabled().

Use DECLARE_DYNDBG_CLASSMAP across DRM:
- in .c files, since macro defines/initializes a record
- in drivers, $mod_{drv,drm,param}.c
ie where param setup is done, since a classmap is param related
- in drm/drm_print.c
since existing __drm_debug param is defined there,
and we ifdef it, and provide an elaborated alternative.
- in drm_*_helper modules:
dp/drm_dp - 1st item in makefile target
drivers/gpu/drm/drm_crtc_helper.c - random pick iirc.
Since these modules all use identical CLASSMAP declarations (ie: names
and .class_id's) they will all respond together to "class DRM_UT_*"
query-commands:
:#> echo class DRM_UT_KMS +p > /proc/dynamic_debug/control
NOTES:
This changes __drm_debug from int to ulong, so BIT() is usable on it.
DRM's enum drm_debug_category values need to sync with the index of
their respective class-names here. Then .class_id == category, and
dyndbg's class FOO mechanisms will enable drm_dbg(DRM_UT_KMS, ...).
Though DRM needs consistent categories across all modules, thats not
generally needed; modules X and Y could define FOO differently (ie a
different NAME => class_id mapping), changes are made according to
each module's private class-map.
No callsites are actually selected by this patch, since none are
class'd yet.

enum drm_debug_category has 10 categories, but is initialized with
bitmasks which require 10 bits of underlying storage. By using
natural enumeration, and moving the BIT(cat) into drm_debug_enabled(),
the enum fits in 4 bits, allowing the category to be represented
directly in pr_debug callsites, via the ddebug.class_id field.
While this slightly pessimizes the bit-test in drm_debug_enabled(),
using dyndbg with JUMP_LABEL will avoid the function entirely.
NOTE: this change forecloses the possibility of doing:
drm_dbg(DRM_UT_CORE|DRM_UT_KMS, "weird 2-cat experiment")
but thats already strongly implied by the use of the enum itself; its
not a normal enum if it can be 2 values simultaneously.

Provide drm_univeral_plane_alloc() to allocate and initialize a
plane. Code for non-atomic drivers uses this pattern. Convert them to
the new function. The modeset helpers contain a quirk for handling their
color formats differently. Set the flag outside plane allocation.
The new function is already deprecated to some extend. Drivers should
rather use drmm_univeral_plane_alloc() or drm_universal_plane_init().

There are some drivers that duplicate this logic in their helpers, such as
