Device specific dev_WARN and dev_WARN_ONCE macros available in kernel include device information in the backtrace, so we know what device the warnings originate from.
Similar to this, add new struct drm_device based drm_WARN* macros. These macros include device information in the backtrace, so we know what device the warnings originate from. Knowing the device specific information in the backtrace would be helpful in development all around.
This patch series aims to convert calls of WARN(), WARN_ON(), WARN_ONCE() and WARN_ON_ONCE() in i916 driver to use the drm device-specific variants automatically wherever struct device pointer is available.
To do this, this patch series -
- introduces new struct drm_device based WARN* macros
- automatically converts WARN* with device specific dev_WARN* variants using coccinelle semantic patch scripts.
The goal is to convert all the calls of WARN* with drm_WARN* in i915, but there are still cases where device pointer is not readily available in some functions (or I missed them somehow) using WARN* hence some manual churning is needed. Handle such remaining cases separately later.

- Address Jani's review comments
- Fix typo in comment of patch 0001
- Get rid of helper functions
- Split patches by directory
Changes since RFC at [1]
- Introduce drm_WARN* macros and use them as suggested by Sam and Jani

Pankaj Bharadiya (10): drm/print: introduce new struct drm_device based WARN* macros
Pushed.
drm/i915/display: Make WARN* drm specific where drm_device ptr is available drm/i915/display: Make WARN* drm specific where drm_priv ptr is available
The above two conflict and need to be rebased.
drm/i915/display: Make WARN* drm specific where encoder ptr is available drm/i915/gem: Make WARN* drm specific where drm_priv ptr is available drm/i915/gt: Make WARN* drm specific where drm_priv ptr is available
Pushed the above three.
drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available drm/i915/gvt: Make WARN* drm specific where vgpu ptr is available
The gvt patches need to be applied through the gvt tree and maintainers once they've backmerged the logging changes.
drm/i915: Make WARN* drm specific where drm_priv ptr is available drm/i915: Make WARN* drm specific where uncore or stream ptr is available
Pushed the above two.
Thanks for the patches.
BR, Jani.
