[Intel-gfx] [PATCH v5 00/21] drm: Introduce struct drm_device based WARN* and use them in i915

[Intel-gfx] [PATCH v5 00/21] drm: Introduce struct drm_device based WARN* and use them in i915

[Pankaj Bharadiya]

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 i915 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 v4:
   - Address Jani's comment
     - split major i915/display related conversions per file into
       seperate patches so that non conflicting patches can be
       merged.

changes since v3:
  - rebase pending unmerged patches on drm-tip
	(bc626bbb5b6e drm-tip: 2020y-01m-25d-14h-28m-41s UTC integration manifest)

changes since v2:
  - rebase pending unmerged patches on drm-tip

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

[Intel-gfx] [PATCH v5 02/21] drm/i915/display/audio: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 03/21] drm/i915/display/cdclk: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 05/21] drm/i915/display/ddi: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 06/21] drm/i915/display/display: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 06/21] drm/i915/display/display: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 07/21] drm/i915/display/power: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 07/21] drm/i915/display/power: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 08/21] drm/i915/display/dp: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 08/21] drm/i915/display/dp: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 09/21] drm/i915/display/dpll_mgr: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 10/21] drm/i915/display/fbc: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch.

[Intel-gfx] [PATCH v5 16/21] drm/i915/display/psr: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch.

[Intel-gfx] [PATCH v5 18/21] drm/i915/display/tc: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 19/21] drm/i915/display: Make WARN* drm specific where drm_device ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 20/21] drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 20/21] drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available

[Pankaj Bharadiya]

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

[Intel-gfx] [PATCH v5 21/21] drm/i915/gvt: Make WARN* drm specific where vgpu ptr is available

[Pankaj Bharadiya]

Drm specific drm_WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.
