Hello,
This series address the discussion on [1], i.e. removing the printk
based logging mechanism and migrate it use dynamic debug.
Patch 1/8 and 2/8 are prep-up patch to pass struct device pointers
so that we can use dev_dbg() in those functions.
Patch 3/8 targets migration of vchiq_log_error() to use dynamic debug
Patch 4/8 targets migration of vchiq_log_warning() to use dynamic debug
Patch 5/8 targets rename of vchiq_log_info() to vchiq_log_debug() and
migration to use dynamic debug.
Patch 6/8 targets mirgration of vchiq_log_trace to use dynamic debug.
Patch 7/8 drops a unused macro.
Patch 8/8 is log levels remnants cleanup along with debugfs entries.
Changes in v2:
- Address feedback from v1, added 1/8, 2/8 as new patches
Hence, Remove pr_*() based logging in few cases
- Cleanup debugfs log entries (8/8) and update TODO list
- Fixed bugs where NULL deference was happening due to unitialised
pointers.
Testing:
Booted RPi 3-b with:
`dyndbg="file *vchiq_arm* +p" dyndbg="file *vchiq_core* +p"`
on cmdline.txt (kernel args)
And run drivers/staging/vc04_services/interface/TESTING and verify
dynamic debug logs with `dmesg -WH`.

Pass struct device pointer to vchiq_log_dump_mem(). In subsequent
commits, vchiq_log_* macros will be ported to use dynamic debug
(dev_dbg()), hence they need access to a struct device pointer.
No functional changes intended in this commit.

Move vchiq_log_error() custom logging wrapper based on printk,
to use dynamic debug. To categorise, enum vchiq_log_category
has been introduced, which will become the part of the error
string format that will be logged to dynamic debug (for grep).
All the vchiq_log_error() calls are adjusted to use the
dynamic debug wrapper. vchiq_loud_error_*() has been removed
as a part of this patch and replaced with dev_err (so that
they directly end up in kernel log, even if dynamic debug
isn't enabled), which serves the purpose.

From: Umang Jain @ 2023-10-24 11:44 UTC (permalink / raw)
To: linux-staging, linux-rpi-kernel, linux-media, linux-arm-kernel
Cc: Stefan Wahren, Greg Kroah-Hartman, Dan Carpenter, Kieran Bingham,
Laurent Pinchart, Phil Elwell, Umang Jain
Move vchiq_log_warning() custom logging wrapper based on printk to use
dynamic debug. The log category is dictated by vchiq_log_category
which will become the part of the warning string format that will be
logged to dynamic debug (for grep).
All the vchiq_log_warning() calls are adjusted to use the
modified wrapper.
While at that, remove the extraneous "----" from few of the
warning string text.

Convert(and rename) vchiq_log_info() custom logging wrapping based on
printk to use dynamic debug. The wrapper is now renamed to
vchiq_log_debug() since most of the usage is around printing debug
information. The log category is dictated by enum vchiq_log_category
which will become the part of the debug string format that will be
logged to dynamic debug (for grep).
All the vchiq_log_info() calls are adjusted to use the
modified wrapper vchiq_log_debug().
The existing custom logging for vchiq_log_info() also tries
to log trace messages using SRVTRACE_LEVEL. This is simply
moved to use the vchiq_log_debug() directly.

Move vchiq_log_trace() custom logging wrapper based on printk
to use dynamic debug. The log category is dictated by enum
vchiq_log_category which will become the part of the trace
string format that will be logged to dynamic debug (for grep).
All the vchiq_log_trace() calls are adjusted to use the
modified wrapper.

Drop the log level remnants since the logs are now ported to use
dynamic logging. Drop macros, externs and global variables which
were used in the log level mechanisms along with debugfs log entries.
Update the drivers/staging/vc04_services/interface/TODO list as well.

Much better, thanks!
But I don't think you're done here, why not just use "real" dev_dbg()
and the like calls instead of your wrapper #defines? What is that
helping with? You now have full debug information so the additional
field should not be needed anymore, right?
I'll take this for now, as any future changes can come on top of this.
thanks,
greg k-h

I dropped this chunk, and the changlog description of it, as I'm not
fully convinced that this portion is done yet. You did the hard work, I
think the remaining tiny bit can probably be scripted.
