Background on Integer scaling:

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:

[PATCH v7 1/4] drm: Introduce plane and CRTC scaling filter properties

[Pankaj Bharadiya]

Introduce per-plane and per-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_create_scaling_filter() and for a CRTC by calling
drm_crtc_create_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.

[Intel-gfx] [PATCH v7 1/4] drm: Introduce plane and CRTC scaling filter properties

[Pankaj Bharadiya]

Introduce per-plane and per-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_create_scaling_filter() and for a CRTC by calling
drm_crtc_create_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: v6:
* Move property doc to existing "Standard CRTC Properties" and
  "Plane Composition Properties" doc comments (Simon)
changes since v3:
* Refactor code, add new function for common code (Ville)
changes since v2:
* Create per-plane and per-CRTC scaling filter property (Ville)
changes since v1:
* None
changes since RFC:
* Add separate properties for plane and CRTC (Ville)

[PATCH v7 3/4] drm/i915/display: Add Nearest-neighbor based integer scaling support

[Pankaj Bharadiya]

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 functions to configure the scaler filter coefficients to
enable nearest-neighbor filtering.

Bspec: 49247

changes since v6:
* Trust compiler, remove pointless inline keyword from cnl_coef_tap()
  & cnl_nearest_filter_coef() functions (Ville)
changes since v4:
* Make cnl_coef_tap(), cnl_nearest_filter_coef() inline (Uma)
changes since v3:
* None
changes since v2:
* Move APIs from 5/5 into this patch.
* Change filter programming related function names to cnl_*, move
  filter select bits related code into inline function (Ville)
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 v7 3/4] drm/i915/display: Add Nearest-neighbor based integer scaling support

[Pankaj Bharadiya]

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 functions to configure the scaler filter coefficients to
enable nearest-neighbor filtering.

Bspec: 49247

changes since v6:
* Trust compiler, remove pointless inline keyword from cnl_coef_tap()
  & cnl_nearest_filter_coef() functions (Ville)
changes since v4:
* Make cnl_coef_tap(), cnl_nearest_filter_coef() inline (Uma)
changes since v3:
* None
changes since v2:
* Move APIs from 5/5 into this patch.
* Change filter programming related function names to cnl_*, move
  filter select bits related code into inline function (Ville)
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)

[PATCH v7 4/4] drm/i915: Enable scaling filter for plane and CRTC

[Pankaj Bharadiya]

GEN >= 10 hardware supports the programmable scaler filter.

Attach scaling filter property for CRTC and plane for GEN >= 10
hardwares and program scaler filter based on the selected filter
type.

changes since v3:
* None
changes since v2:
* Use updated functions
* Add ps_ctrl var to contain the full PS_CTRL register value (Ville)
* Duplicate the scaling filter in crtc and plane hw state (Ville)
changes since v1:
* None
Changes since RFC:
* Enable properties for GEN >= 10 platforms (Ville)
* Do not round off the crtc co-ordinate (Danial Stone, Ville)
* Add new functions to handle scaling filter setup (Ville)
* Remove coefficient set 0 hardcoding.

[Intel-gfx] [PATCH v7 4/4] drm/i915: Enable scaling filter for plane and CRTC

[Pankaj Bharadiya]

GEN >= 10 hardware supports the programmable scaler filter.

Attach scaling filter property for CRTC and plane for GEN >= 10
hardwares and program scaler filter based on the selected filter
type.

changes since v3:
* None
changes since v2:
* Use updated functions
* Add ps_ctrl var to contain the full PS_CTRL register value (Ville)
* Duplicate the scaling filter in crtc and plane hw state (Ville)
changes since v1:
* None
Changes since RFC:
* Enable properties for GEN >= 10 platforms (Ville)
* Do not round off the crtc co-ordinate (Danial Stone, Ville)
* Add new functions to handle scaling filter setup (Ville)
* Remove coefficient set 0 hardcoding.
