Hi Marek, Currently, IPP v2 and gsc do not seem to have any code to check for hardware limits. How can I check the hardware limits of device(gsc, rotator, ...) at IPP v2?
From userspace one can issue DRM_IOCTL_EXYNOS_IPP_GET_LIMITS ioctl, some examples can be found in Tobias' libdrm git: https://github.com/tobiasjakobi/libdrm/blob/ippv2/exynos/exynos_ipp.c In the current version of patches, GSC and FIMC drivers have no limits defined, because the old v1 IPP drivers didn't have such information. I will try to add them in v3 of this patchset, I will also include your recently proposed updates to GSC driver bindings and rotated image size limit. > ...
