From: Dillon Min <dillon.minfei@xxxxxxxxx> This patchset introduces a basic support for DMA2D Interface of STMicroelectronics STM32 SoC series. This first basic support implements R2M, M2M, M2M_PFC M2M_BLEND support will be added later on. This has been tested on STM32469-DISCO board. The commit based on kernel(master): c3d0e3fd41b7f0f5d5d5b6022ab7e813f04ea727 Note for v4l2-compliance tool on nu-mmu platform: I add two change based on v4l-utils since commit: f0c7e3d71eaf4182bae7eb3ee0e43b4eeb047ea9 - change fork() to vfork() in v4l2-test-controls.cpp since no-mmu platform don't include fork(). - bypass VIDIOC_QUERYCAP nullptr check I'm not sure if this is the bug from my cross compile tool which created by buildroot. user area's nullptr can't be detected by kernel side, i was try to add access_ok() in v4l2-ioctl.c, but no help If this case must be fixed, i will continue to debug it. the error log: ... fail: v4l2-compliance.cpp(623): doioctl(node, VIDIOC_QUERYCAP, nullptr) != EFAULT ..
