If you can't say smaller total object code that performs the same task identically is better, I think we can't discuss much of anything about code together. Any printk related mechanism is not fast-path so any icache dilution isn't an issue. > That said, I'm not arguing against this patch as such.

Sure, it's just any such a discussion should not affect this patch being applied. This patch reduces the argument count of the drm_printk (now drm_dbg) call and so is faster to execute even if the emit test is internal to the drm_dbg function. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
