Subject: [[Intel-gfx] [PATCH v2 00/10] drm: Introduce struct drm_device based WARN* and use them in i915
Date: Wed, 15 Jan 2020 09:14:44 +0530
Message-ID: <20200115034455.17658-1-pankaj.laxminarayan.bharadiya@intel.com> (raw)

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.

changes since v1:
  - 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
  - Get rid of extra local variables
