There is no DRM_WARN inconsistency. What is used is pr_warn and dev_warn, not pr_warning and dev_warning Well, there are still a few pr_warning uses, but those will eventually be removed/converted. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 13+ messages in thread

To me, simplifying the macro means using the common kernel macro forms. _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 13+ messages in thread

And for static inlines we more often want to know which of the many callers triggered the error. We would have to play it by ear to see which error messages need to be improved in cases where it not obvious without the context of the static inline function name. Lgtm, reducing the call size for DRM_DEBUG is a definite improvement.

I would rather see us to migrate to DRM_DEV (i.e. dev_printk) so that the drm subsystem is consistent with the rest of the kernel and providing the necessary information for syslog filtering. -Chris -- Chris Wilson, Intel Open Source Technology Centre ^ permalink raw reply [flat|nested] 13+ messages in thread
