The IPU can upscale and downscale a source frame of arbitrary size ranging from 4x4 to 4096x4096 on newer SoCs, with bicubic filtering on newer SoCs, bilinear filtering on older SoCs. Nearest-neighbour can also be obtained with proper coefficients. Starting from the JZ4725B, the IPU supports a mode where its output is sent directly to the LCDC, without having to be written to RAM first. This makes it possible to use the IPU as a DRM plane on the compatible SoCs, and have it convert and scale anything the userspace asks for to what's available for the display. Regarding pixel formats, older SoCs support packed YUV 4:2:2 and various planar YUV formats. Newer SoCs introduced support for RGB. Since the IPU is a separate hardware block, to make it work properly the Ingenic DRM driver will now register itself as a component master in case the IPU driver has been enabled in the config. When enabled in the config, the CRTC will see the IPU as a second primary plane. It cannot be enabled at the same time as the regular primary plane. It has the same priority, which means that it will also display below the overlay plane. Signed-off-by: Paul Cercueil --- Notes: v2: - ingenic-ipu is no longer its own module. It will be built into the ingenic-drm module. - If enabled in the config, both the core driver and the IPU driver will register as components; otherwise the core driver will bypass that and call the ingenic_drm_bind() function directly. - Since both files now build into the same module, the symbols previously exported as GPL are not exported anymore, since they are only used internally. - Fix SPDX license header in ingenic-ipu.h - Avoid using 'for(;;);' loops without trailing statement(s) drivers/gpu/drm/ingenic/Kconfig | 11 + drivers/gpu/drm/ingenic/Makefile | 3 +- drivers/gpu/drm/ingenic/ingenic-drm-drv.c | 155 +++- drivers/gpu/drm/ingenic/ingenic-drm.h | 12 + drivers/gpu/drm/ingenic/ingenic-ipu.c | 848 ++++++++++++++++++++++ drivers/gpu/drm/ingenic/ingenic-ipu.h | 109 +++ 6 files changed, 1122 insertions(+), 16 deletions(-) create mode 100644 drivers/gpu/drm/ingenic/ingenic-ipu.c create mode 100644 drivers/gpu/drm/ingenic/ingenic-ipu.h diff --git a/drivers/gpu/drm/ingenic/Kconfig b/drivers/gpu/drm/ingenic/Kconfig index d82c3d37ec9c..477d5387e43e 100644 --- a/drivers/gpu/drm/ingenic/Kconfig +++ b/drivers/gpu/drm/ingenic/Kconfig @@ -14,3 +14,14 @@ config DRM_INGENIC Choose this option for DRM support for the Ingenic SoCs.
