[Intel-gfx] [RFC 0/7] drm/i915: Convert WARN* to use device-specific variants
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. 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() to use the device-specific variants automatically wherever struct device pointer is available. To do this, this patch series - - modifies the existing dev_WARN macro to support conditional warning like WARN so that WARNs can be replaced with dev_WARN - add dev_WARN_ON and dev_WARN_ON_ONCE macros device specific macros similar to WARN_ON and WARN_ON_ONCE into i915 - automatically convert WARN* with device specific dev_WARN* variants using coccinelle semantic patch scripts. The goal is to convert all the calls of WARN* with dev_WARN*, but there are still cases where device pointer is not readily available in some functions (or I missed them somehow) having warning hence some manual churning is needed. Handle such remaining cases separately later.

[Intel-gfx] [PATCH v7 0/8] drm: Introduce struct drm_device based WARN* and use them in i915
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 v6: - rebase unmerged patches onto drm-tip (07350317e4b2 dm-tip: 2020y-02m-20d-12h-11m-40s UTC integration manifest) changes since v5: - rebase unmerged patches onto drm-tip (db0579be2554 drm-tip: 2020y-02m-05d-10h-51m-13s UTC integration manifest) 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 [1] https://patchwork.freedesktop.org/series/71668/ Pankaj Bharadiya (8): drm/i915/display/cdclk: Make WARN* drm specific where drm_priv ptr is available drm/i915/display/ddi: Make WARN* drm specific where drm_device ptr is available drm/i915/display/display: Make WARN* drm specific where drm_device ptr is available drm/i915/display/power: Make WARN* drm specific where drm_priv ptr is available drm/i915/display/dp: Make WARN* drm specific where drm_device ptr is available drm/i915/display/hdcp: Make WARN* drm specific where drm_priv ptr is available 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 drivers/gpu/drm/i915/display/intel_cdclk.c| 84 --- drivers/gpu/drm/i915/display/intel_ddi.c | 92 --- drivers/gpu/drm/i915/display/intel_display.c | 237 ++ .../drm/i915/display/intel_display_power.c| 181 +++-- drivers/gpu/drm/i915/display/intel_dp.c | 120 + drivers/gpu/drm/i915/display/intel_hdcp.c | 20 +- drivers/gpu/drm/i915/gvt/aperture_gm.c| 6 +- drivers/gpu/drm/i915/gvt/cfg_space.c | 23 +- drivers/gpu/drm/i915/gvt/cmd_parser.c | 4 +- drivers/gpu/drm/i915/gvt/display.c| 6 +- drivers/gpu/drm/i915/gvt/dmabuf.c | 4 +- drivers/gpu/drm/i915/gvt/edid.c | 19 +- drivers/gpu/drm/i915/gvt/gtt.c| 21 +- drivers/gpu/drm/i915/gvt/gvt.c| 4 +- drivers/gpu/drm/i915/gvt/handlers.c | 22 +- drivers/gpu/drm/i915/gvt/interrupt.c | 15 +- drivers/gpu/drm/i915/gvt/kvmgt.c | 10 +- drivers/gpu/drm/i915/gvt/mmio.c | 30 ++- drivers/gpu/drm/i915/gvt/mmio_context.c | 8 +- drivers/gpu/drm/i915/gvt/scheduler.c | 6 +- drivers/gpu/drm/i915/gvt/vgpu.c | 6 +- 21 files changed, 537 insertions(+), 381 deletions(-) -- 2.23.0 ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

[RFC][PATCH 0/5] Introduce drm scaling filter property
Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier. Nearest-neighbor (NN) interpolation works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. Both IS and NN preserve the clarity of the original image. In contrast, traditional upscaling algorithms, such as bilinear or bicubic interpolation, result in blurry upscaled images because they employ interpolation techniques that smooth out the transition from one pixel to another. Therefore, integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look. Many gaming communities have been asking for integer-mode scaling support, some links and background: https://software.intel.com/en-us/articles/integer-scaling-support-on-intel-graphics http://tanalin.com/en/articles/lossless-scaling/ https://community.amd.com/thread/209107 https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/1002/feature-request-nonblurry-upscaling-at-integer-rat/ This patch series - - Introduces new scaling filter property to allow userspace to select the driver's default scaling filter or Nearest-neighbor(NN) filter for scaling operations on crtc/plane. - Implements and enable integer scaling for i915 Userspace patch series link: TBD. Thanks to Shashank for initiating this work. His initial RFC can be found here [1] [1] https://patchwork.freedesktop.org/patch/337082/ Modifications done in this series - - refactored code and incorporated initial review comments and added 2 scaling filter types (default and NN) to begin with. - added scaling filter property support for planes and new API helpers for drivers to setup this property. - rewrote code to enable integer scaling and NN filter for i915 Pankaj Bharadiya (5): drm: Introduce scaling filter property drm/drm-kms.rst: Add Scaling filter property documentation drm/i915: Enable scaling filter for plane and pipe drm/i915: Introduce scaling filter related registers and bit fields. drm/i915/display: Add Nearest-neighbor based integer scaling support Documentation/gpu/drm-kms.rst| 6 ++ drivers/gpu/drm/drm_atomic_uapi.c| 8 ++ drivers/gpu/drm/drm_crtc.c | 16 +++ drivers/gpu/drm/drm_mode_config.c| 13 +++ drivers/gpu/drm/drm_plane.c | 35 +++ drivers/gpu/drm/i915/display/intel_display.c | 100 ++- drivers/gpu/drm/i915/display/intel_display.h | 2 + drivers/gpu/drm/i915/display/intel_sprite.c | 32 -- drivers/gpu/drm/i915/i915_reg.h | 21 include/drm/drm_crtc.h | 10 ++ include/drm/drm_mode_config.h| 6 ++ include/drm/drm_plane.h | 14 +++ 12 files changed, 252 insertions(+), 11 deletions(-) -- 2.23.0 ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

the driver's default scaling filter or Nearest-neighbor(NN) filter
for upscaling operations on crtc/plane.
Drivers can set up this property for a plane by calling
drm_plane_enable_scaling_filter() and for a CRTC by calling
drm_crtc_enable_scaling_filter().
NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.
NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.

[RFC][PATCH 5/5] drm/i915/display: Add Nearest-neighbor based integer scaling support
Integer scaling (IS) is a nearest-neighbor upscaling technique that
simply scales up the existing pixels by an integer
(i.e., whole number) multiplier.Nearest-neighbor (NN) interpolation
works by filling in the missing color values in the upscaled image
with that of the coordinate-mapped nearest source pixel value.
Both IS and NN preserve the clarity of the original image. Integer
scaling is particularly useful for pixel art games that rely on
sharp, blocky images to deliver their distinctive look.
Program the scaler filter coefficients to enable the NN filter if
scaling filter property is set to DRM_SCALING_FILTER_NEAREST_NEIGHBOR
and enable integer scaling.

[Intel-gfx][PATCH 01/10] drm/i915: Add i915 device based MISSING_CASE macro
Now that we have struct drm_device based drm_WARN, introduce struct drm_i915_private based i915_MISSING_CASE macro which uses drm_WARN so that device specific information will also get printed in backtrace. i915_MISSING_CASE macro should be preferred over MISSING_CASE, wherever possible.

[PATCH 0/9] drm: drm_fb_helper cleanup.
This series addresses below drm_fb_helper tasks from
Documentation/gpu/todo.rst.
- The max connector argument for drm_fb_helper_init() isn't used
anymore and can be removed.
- The helper doesn't keep an array of connectors anymore so these can
be removed: drm_fb_helper_single_add_all_connectors(),
drm_fb_helper_add_one_connector() and
drm_fb_helper_remove_one_connector().
Pankaj Bharadiya (9):
drm: Remove unused arg from drm_fb_helper_init
drm/radeon: remove radeon_fb_{add,remove}_connector functions
drm/amdgpu: Remove drm_fb_helper_{add,remove}_one_connector calls
drm/i915/display: Remove drm_fb_helper_{add,remove}_one_connector calls
drm: Remove drm_fb_helper add, add all and remove connector calls
drm/nouveau: Fix unused variable warning
drm/bridge: remove unused variable warning in tc358764_detach
drm/fb-helper: Remove drm_fb_helper add, add_all and remove connector
functions
drm/todo: Update drm_fb_helper tasks

[PATCH 3/9] drm/amdgpu: Remove drm_fb_helper_{add, remove}_one_connector calls
drm_fb_helper_{add,remove}_one_connector() are dummy functions now
and serve no purpose. Hence remove their calls.
This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h

drm_fb_helper_single_add_all_connectors(), drm_fb_helper_add_one_connector()
and drm_fb_helper_remove_one_connector() doesn't keep an array of
connectors anymore and are just dummy. Now we have no callers to these
functions hence remove them.

[PATCH v2 0/7] drm: drm_fb_helper cleanup.
This series addresses below drm_fb_helper tasks from
Documentation/gpu/todo.rst.
- The max connector argument for drm_fb_helper_init() isn't used
anymore and can be removed.
- The helper doesn't keep an array of connectors anymore so these can
be removed: drm_fb_helper_single_add_all_connectors(),
drm_fb_helper_add_one_connector() and
drm_fb_helper_remove_one_connector().
Changes since v1:
- Squashed warning fixes into the patch that introduced the
warnings (into 5/7) (Laurent)
- Fixed reflow in in 9/9 (Laurent)

[RESEND PATCH v2 0/7] drm: drm_fb_helper cleanup.
This series addresses below drm_fb_helper tasks from
Documentation/gpu/todo.rst.
- The max connector argument for drm_fb_helper_init() isn't used
anymore and can be removed.
- The helper doesn't keep an array of connectors anymore so these can
be removed: drm_fb_helper_single_add_all_connectors(),
drm_fb_helper_add_one_connector() and
drm_fb_helper_remove_one_connector().
Changes since v1:
- Accumulated all review tags into individual commits (Emil, Daniel)
- Squashed warning fixes into the patch that introduced the
warnings (into 5/7) (Laurent, Emil, Lyude)
- Remove entire drm_fb_helper tasks from todo list. Daniel's
"64914da24ea9 drm/fbdev-helper: don't force restores" fixes first
one (Daniel)
Pankaj Bharadiya (7):
drm: Remove unused arg from drm_fb_helper_init
drm/radeon: remove radeon_fb_{add,remove}_connector functions
drm/amdgpu: Remove drm_fb_helper_{add,remove}_one_connector calls
drm/i915/display: Remove drm_fb_helper_{add,remove}_one_connector calls

[PATCH 2/5] drm: Remove dp mst register connector callbacks
drm_dp_mst_port_add_connector() directly calls the
drm_connector_register() now and
drm_dp_mst_topology_mgr_cbs.register_connector callback is not getting
called anymore.
Hence remove all drm_dp_mst_topology_mgr_cbs.register_connector
callbacks.
This is the preparatory step for removing the
drm_dp_mst_topology_mgr_cbs.register_connector callback hook.
The removal is done with below sementic patch:

[PATCH 1/5] drm: Introduce plane and CRTC scaling filter properties
Introduce new plane and CRTC scaling filter properties to allow
userspace to select the driver's default scaling filter or
Nearest-neighbor(NN) filter for upscaling operations on CRTC and
plane.
Drivers can set up this property for a plane by calling
drm_plane_enable_scaling_filter() and for a CRTC by calling
drm_crtc_enable_scaling_filter().
NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.
NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.

[PATCH 0/5] Introduce drm scaling filter property
This series is the continuation for the RFC that I posted earlier [1] [1] RFC: https://patchwork.freedesktop.org/series/73884/ Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier. Nearest-neighbor (NN) interpolation works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. Both IS and NN preserve the clarity of the original image. In contrast, traditional upscaling algorithms, such as bilinear or bicubic interpolation, result in blurry upscaled images because they employ interpolation techniques that smooth out the transition from one pixel to another. Therefore, integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look.

[PATCH 4/5] drm/i915/display: Add Nearest-neighbor based integer scaling support
Integer scaling (IS) is a nearest-neighbor upscaling technique that
simply scales up the existing pixels by an integer
(i.e., whole number) multiplier.Nearest-neighbor (NN) interpolation
works by filling in the missing color values in the upscaled image
with that of the coordinate-mapped nearest source pixel value.
Both IS and NN preserve the clarity of the original image. Integer
scaling is particularly useful for pixel art games that rely on
sharp, blocky images to deliver their distinctive look.
Introduce skl_scaler_setup_nearest_neighbor_filter() function which
configures the scaler filter coefficients to enable nearest-neighbor
filtering.

[PATCH v2 1/5] drm: Introduce plane and CRTC scaling filter properties
Introduce new plane and CRTC scaling filter properties to allow
userspace to select the driver's default scaling filter or
Nearest-neighbor(NN) filter for upscaling operations on CRTC and
plane.
Drivers can set up this property for a plane by calling
drm_plane_enable_scaling_filter() and for a CRTC by calling
drm_crtc_enable_scaling_filter().
NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.
NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.
changes since v1:
* None
changes since RFC:
* Add separate properties for plane and CRTC (Ville)

[PATCH v2 4/5] drm/i915/display: Add Nearest-neighbor based integer scaling support
Integer scaling (IS) is a nearest-neighbor upscaling technique that
simply scales up the existing pixels by an integer
(i.e., whole number) multiplier.Nearest-neighbor (NN) interpolation
works by filling in the missing color values in the upscaled image
with that of the coordinate-mapped nearest source pixel value.
Both IS and NN preserve the clarity of the original image. Integer
scaling is particularly useful for pixel art games that rely on
sharp, blocky images to deliver their distinctive look.
Introduce skl_scaler_setup_nearest_neighbor_filter() function which
configures the scaler filter coefficients to enable nearest-neighbor
filtering.
Bspec: 49247
changes since v1:
* Rearrange skl_scaler_setup_nearest_neighbor_filter() to iterate the
registers directly instead of the phases and taps (Ville)
changes since RFC:
* Refine the skl_scaler_setup_nearest_neighbor_filter() logic (Ville)

[Intel-gfx] [PATCH 0/6]: drm: Introduce struct drm_device based WARN* and use them in i915
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 RFC at [1] - Introduce drm_WARN* macros and use them as suggested by Sam and Jani - Get rid of extra local variables [1] https://patchwork.freedesktop.org/series/71668/ Pankaj Bharadiya (6): drm/print: introduce new struct drm_device based WARN* macros drm/i915: add helper functions to get device ptr drm/i915: Make WARN* drm specific where drm_device ptr available drm/i915: Make WARN* drm specific where drm_priv ptr is available drm/i915: Make WARN* drm specific where dev_priv can be extracted. drm/i915: Make WARN* drm specific for various cases. drivers/gpu/drm/i915/display/icl_dsi.c| 14 +- drivers/gpu/drm/i915/display/intel_atomic.c | 6 +- drivers/gpu/drm/i915/display/intel_audio.c| 19 +- drivers/gpu/drm/i915/display/intel_bios.c | 10 +- drivers/gpu/drm/i915/display/intel_bw.c | 3 +- drivers/gpu/drm/i915/display/intel_cdclk.c| 81 +++--- drivers/gpu/drm/i915/display/intel_color.c| 3 +- .../gpu/drm/i915/display/intel_combo_phy.c| 2 +- .../gpu/drm/i915/display/intel_connector.c| 3 +- drivers/gpu/drm/i915/display/intel_crt.c | 10 +- drivers/gpu/drm/i915/display/intel_ddi.c | 100 drivers/gpu/drm/i915/display/intel_display.c | 239 ++ .../drm/i915/display/intel_display_power.c| 170 +++-- .../drm/i915/display/intel_display_types.h| 14 + drivers/gpu/drm/i915/display/intel_dp.c | 121 + drivers/gpu/drm/i915/display/intel_dp_mst.c | 10 +- drivers/gpu/drm/i915/display/intel_dpio_phy.c | 3 +- drivers/gpu/drm/i915/display/intel_dpll_mgr.c | 39 +-- drivers/gpu/drm/i915/display/intel_dsb.c | 6 +- .../i915/display/intel_dsi_dcs_backlight.c| 2 +- drivers/gpu/drm/i915/display/intel_dsi_vbt.c | 5 +- drivers/gpu/drm/i915/display/intel_fbc.c | 23 +- drivers/gpu/drm/i915/display/intel_fbdev.c| 13 +- drivers/gpu/drm/i915/display/intel_gmbus.c| 3 +- drivers/gpu/drm/i915/display/intel_hdcp.c | 21 +- drivers/gpu/drm/i915/display/intel_hdmi.c | 71 +++--- drivers/gpu/drm/i915/display/intel_hotplug.c | 7 +- .../gpu/drm/i915/display/intel_lpe_audio.c| 2 +- drivers/gpu/drm/i915/display/intel_lvds.c | 7 +- drivers/gpu/drm/i915/display/intel_opregion.c | 7 +- drivers/gpu/drm/i915/display/intel_overlay.c | 18 +- drivers/gpu/drm/i915/display/intel_panel.c| 21 +- drivers/gpu/drm/i915/display/intel_pipe_crc.c | 7 +- drivers/gpu/drm/i915/display/intel_psr.c | 32 ++- drivers/gpu/drm/i915/display/intel_sdvo.c | 17 +- drivers/gpu/drm/i915/display/intel_sprite.c | 5 +- drivers/gpu/drm/i915/display/intel_tc.c | 17 +- drivers/gpu/drm/i915/display/intel_vdsc.c | 2 +- drivers/gpu/drm/i915/display/vlv_dsi.c| 2 +- .../gpu/drm/i915/gem/i915_gem_execbuffer.c| 4 +- drivers/gpu/drm/i915/gem/i915_gem_pm.c| 4 +- drivers/gpu/drm/i915/gem/i915_gem_shmem.c | 3 +- drivers/gpu/drm/i915/gem/i915_gem_shrinker.c | 13 +- drivers/gpu/drm/i915/gem/i915_gem_stolen.c| 15 +- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 10 +- drivers/gpu/drm/i915/gt/intel_engine_user.c | 3 +- drivers/gpu/drm/i915/gt/intel_gt_irq.c| 15 +- drivers/gpu/drm/i915/gt/intel_gt_pm_irq.c | 2 +- drivers/gpu/drm/i915/gt/intel_gtt.c | 6 +- drivers/gpu/drm/i915/gt/intel_mocs.c | 4 +- drivers/gpu/drm/i915/gt/intel_rc6.c | 2 +- .../gpu/drm/i915/gt/intel_ring_submission.c | 7 +- drivers/gpu/drm/i915/gt/intel_rps.c | 21 +- drivers/gpu/drm/i915/gt/intel_workarounds.c | 2 +- drivers/gpu/drm/i915/gvt/aperture_gm.c| 6 +- drivers/gpu/drm/i915/gvt/cfg_space.c | 20 +- drivers/gpu/drm/i915/gvt/cmd_parser.c | 4 +- drivers/gpu/drm/i915/gvt

[Intel-gfx] [PATCH v3 0/4] drm: Introduce struct drm_device based WARN* and use them in i915
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 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 [1] https://patchwork.freedesktop.org/series/71668/ Pankaj Bharadiya (4): 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 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 drivers/gpu/drm/i915/display/icl_dsi.c| 14 +- drivers/gpu/drm/i915/display/intel_atomic.c | 6 +- drivers/gpu/drm/i915/display/intel_audio.c| 19 +- drivers/gpu/drm/i915/display/intel_bios.c | 10 +- drivers/gpu/drm/i915/display/intel_bw.c | 3 +- drivers/gpu/drm/i915/display/intel_cdclk.c| 81 --- drivers/gpu/drm/i915/display/intel_color.c| 4 +- .../gpu/drm/i915/display/intel_combo_phy.c| 2 +- .../gpu/drm/i915/display/intel_connector.c| 3 +- drivers/gpu/drm/i915/display/intel_crt.c | 10 +- drivers/gpu/drm/i915/display/intel_ddi.c | 94 drivers/gpu/drm/i915/display/intel_display.c | 218 ++ .../drm/i915/display/intel_display_power.c| 167 -- drivers/gpu/drm/i915/display/intel_dp.c | 117 ++ drivers/gpu/drm/i915/display/intel_dp_mst.c | 10 +- drivers/gpu/drm/i915/display/intel_dpio_phy.c | 3 +- drivers/gpu/drm/i915/display/intel_dpll_mgr.c | 37 +-- drivers/gpu/drm/i915/display/intel_dsb.c | 6 +- .../i915/display/intel_dsi_dcs_backlight.c| 2 +- drivers/gpu/drm/i915/display/intel_dsi_vbt.c | 5 +- drivers/gpu/drm/i915/display/intel_fbc.c | 23 +- drivers/gpu/drm/i915/display/intel_fbdev.c| 13 +- drivers/gpu/drm/i915/display/intel_gmbus.c| 3 +- drivers/gpu/drm/i915/display/intel_hdcp.c | 21 +- drivers/gpu/drm/i915/display/intel_hdmi.c | 51 ++-- drivers/gpu/drm/i915/display/intel_hotplug.c | 7 +- .../gpu/drm/i915/display/intel_lpe_audio.c| 2 +- drivers/gpu/drm/i915/display/intel_lvds.c | 7 +- drivers/gpu/drm/i915/display/intel_opregion.c | 7 +- drivers/gpu/drm/i915/display/intel_overlay.c | 12 +- drivers/gpu/drm/i915/display/intel_panel.c| 19 +- drivers/gpu/drm/i915/display/intel_pipe_crc.c | 7 +- drivers/gpu/drm/i915/display/intel_psr.c | 34 +-- drivers/gpu/drm/i915/display/intel_sdvo.c | 14 +- drivers/gpu/drm/i915/display/intel_sprite.c | 5 +- drivers/gpu/drm/i915/display/intel_tc.c | 17 +- drivers/gpu/drm/i915/display/intel_vdsc.c | 2 +- drivers/gpu/drm/i915/display/vlv_dsi.c| 2 +- drivers/gpu/drm/i915/gvt/aperture_gm.c| 6 +- drivers/gpu/drm/i915/gvt/cfg_space.c | 23 +- drivers/gpu/drm/i915/gvt/cmd_parser.c | 4 +- drivers/gpu/drm/i915/gvt/display.c| 6 +- drivers/gpu/drm/i915/gvt/dmabuf.c | 4 +- drivers/gpu/drm/i915/gvt/edid.c | 19 +- drivers/gpu/drm/i915/gvt/gtt.c| 21 +- drivers/gpu/drm/i915/gvt/gvt.c| 4 +- drivers/gpu/drm/i915/gvt/handlers.c | 22 +- drivers/gpu/drm/i915/gvt/interrupt.c | 15 +- drivers/gpu/drm/i915/gvt/kvmgt.c | 10 +- drivers/gpu/drm/i915/gvt/mmio.c | 30 ++- drivers/gpu/drm/i915/gvt/mmio_context.c | 8 +- drivers/gpu/drm/i915/gvt/scheduler.c | 6 +- drivers/gpu/drm/i915/gvt/vgpu.c | 6 +- 53 files changed, 714 insertions(+), 527 deletions(-) -- 2
