From: Dillon Min <dillon.minfei@gmail.com> 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. history v2: - update v4l2-compliance to SHA: a4f2e3a6f306 2021-07-13 08:04:15 the test results at below [1]. - introduce Documentation/userspace-api/media/drivers/stm32-uapi.rst to explain the detail of dma2d's ioctl. - reserved 16 ioctls from v4l2-controls.h for stm32, introduce stm32-media.h. - collect Reviewed-by tag from Rob Herring. - update dma2d driver from Hans's review. the details can be found at related patches. v1 link: https://lore.kernel.org/lkml/1621508727-24486-1-git-send-email-dillon.minfei@gmail.com/ v1: 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 .. My changes on v4l2-compliance: with v4l2-compliance test log (with above modification): since the stm32f469-disco ram limitation, there are 25 failed on dma_alloc_coherent() Really appreciate if someone can help to test this patch on the STM32429I-EVAL evaluation board (https://www.st.com/en/evaluation-tools/stm32429i-eval.html) 8M x 32-bit SDRAM, 1M x 16-bit SRAM and 8M x 16-bit NOR Flash / # free total used free shared buffers cached Mem: 15604 6104 9500 0 0 2488 -/+ buffers/cache: 3616 11988 [1] v4l2-compliance test result: ./v4l2-compliance -s -f -d /dev/video0 & [1] 34 ./v4l2-compliance -s -f -d /dev/video0 / # v4l2-compliance 1.21.0-4831, 32 bits, 32-bit time_t v4l2-compliance SHA: a4f2e3a6f306 2021-07-13 08:04:15 Compliance test for stm-dma2d device /dev/video0: Driver Info: Driver name : stm-dma2d Card type : stm-dma2d Bus info : platform:stm-dma2d Driver version : 5.14.0 Capabilities : 0x84208000 Video Memory-to-Memory Streaming Extended Pix Format Device Capabilities Device Caps : 0x04208000 Video Memory-to-Memory Streaming Extended Pix Format Required ioctls: test VIDIOC_QUERYCAP: OK test invalid ioctls: OK Allow for multiple opens: test second /dev/video0 open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK test for unlimited opens: OK Debug ioctls: test VIDIOC_DBG_G/S_REGISTER: OK (Not Supported) test VIDIOC_LOG_STATUS: OK (Not Supported) Input ioctls: test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 0 Audio Inputs: 0 Tuners: 0 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK (Not Supported) test VIDIOC_DV_TIMINGS_CAP: OK (Not Supported) test VIDIOC_G/S_EDID: OK (Not Supported)[ Control ioctls: test VIDIOC_QUERY_EX _CTRL/QUERY ENU: 55.029750] stm-dma2d 4002b000.dma2d: Format not supported: ▒▒▒▒, use the default.
