drm/printer: Allow NULL data in devcoredump printer

2024-08-01T18:00:12+00:00

We want to determine the size of the devcoredump before writing it out. To that end, we will run the devcoredump printer with NULL data to get the size, alloc data based on the generated offset, then run the devcorecump again with a valid data pointer to print. This necessitates not writing data to the data pointer on the initial pass, when it is NULL. v5: - Better commit message (Jonathan) - Add kerenl doc with examples (Jani) Cc: Maarten Lankhorst Acked-by: Maarten Lankhorst Signed-off-by: Matthew Brost Reviewed-by: Jonathan Cavitt Link: https://patchwork.freedesktop.org/patch/msgid/20240801154118.2547543-3-matthew.brost@intel.com

drm/print: Improve drm_dbg_printer

2024-06-06T18:46:15+00:00

With recent introduction of a generic drm dev printk function, we can now store and use location where drm_dbg_printer was invoked and output it's symbolic name like we do for all drm debug prints.

drm/print: Kill ___drm_dbg()

There is no point in maintaining a separate print function, while there is __drm_dev_dbg() function that can work with a NULL device.

drm: remove drm_debug_printer in favor of drm_dbg_printer

2024-02-09T09:52:43+00:00

Convert the remaining drm_debug_printer users over to drm_dbg_printer, as it can handle the cases without struct drm_device pointer, and also provides drm debug category and prefix support. Remove drm_debug_printer altogether.

drm/print: add drm_dbg_printer() for drm device specific printer

2024-02-09T09:51:53+00:00

We've lacked a device specific debug printer. Add one. Take category into account too. __builtin_return_address(0) is inaccurate here, so don't use it. If necessary, we can later pass __func__ to drm_dbg_printer() by wrapping it inside a macro.
