This patchset converts logging to drm_* functions in drm core.
The following functions have been converted to their respective DRM alternatives : dev_info() --> drm_info() dev_err() --> drm_err() dev_warn() --> drm_warn() dev_err_once() --> drm_err_once().
I would prefer that DRM_* logging in the same files are converted in the same patch. So we have one logging conversion patch for each file you touches and that we do not need to re-vist the files later to change another set of logging functions.
Agreed.
If possible WARN_* should also be converted to drm_WARN_* If patch is too large, then split them up but again lets have all logging updated when we touch a file.
Care to take a look at this approach?
Hii, The problem with WARN_* macros is that they are used without any drm device context. For example [this use here](https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_edid.c#n1...) in drm_edid.c, doesn't have a drm device context and only has one argument (namely !raw_edid). There are many more such use cases.
And also there were cases where dev_* logging functions didn't have any drm_device context.
I would be very glad, if we came up with a possible solution to this problem. I think we should develop drm_* logging APIs which could print contextless logs (which would possibly be midlyering) or give every situation a context.
This was discussed in the past. For now the focus is migrating existing logging to the new drm_ based logging. Preferably using coccinelle. when we are more or less covered there we can discuss if we will add more logging functions.
Also please consider if coccinelle can make this job easier. There is a lot of files...
I totally agree with you. I will remember this next time.
But here, in this patchset I have tried to convert all possible cases of conversion, i.e. I have changed logging wherever there was a drm_device context.
Please note this in the changelog when you resend. I delete your original patches so they are gone now from my mail-box. Yeah, could dig them up somewhere, but it is easier to let you resend them and then we can have an updated changelog too.

Thanks.
