The wave5 codec is a stateful encoder/decoder. It is found on the JH7100 SoC. The driver currently supports V4L2_PIX_FMT_HEVC, V4L2_PIX_FMT_H264. This driver has so far been tested on pre-silicon FPGA and on the beta BeagleV board which uses the StarFive JH7100 beta SoC. Testing on FPGA shows it working fine, though the FPGA uses polled interrupts and copied buffers between the host and it's on board RAM. Testing on BeagleV shows buffer corruption that is currently attributed to a known silicon issue in the SoC that makes the cache coherent interconnect not so coherent. This can likely be solved when the riscv non-coherent dma support lands and provide optional v4l2 non-contiguous allocator, though it remains to be seen whether support non-coherent use cases will be useful in real world hw. Until we can test and resolve any issues on final silicon (due 2H 2021) this driver should remain in staging. We currently tested only the decoder. Testing the encoder is currently impossible because of the BeagleV buffer problems, That will need to be tested once we have fixed beaglev buffer problems. v4l2-compliance all pass for v2 as well. changes since v1: Fix chanes due to comments from Ezequiel and Dan Carpenter. Main fixes inclueds: * move all files to one dir 'wave5' * replace private error codes with standart error codes * fix extra spaces * various checkpatch fixes * replace private 'DPRINTK' macro with standart 'dev_err/dbg ..' * fix error handling * add more possible fixes to the TODO file Dafna Hirschfeld (4): staging: media: wave5: Add vpuapi layer staging: media: wave5: Add the vdi layer staging: media: wave5: Add the v4l2 layer staging: media: wave5: Add TODO file Robert Beckett (2): dt-bindings: media: staging: wave5: add yaml devicetree bindings media: wave5: Add wave5 driver to maintainers file .../bindings/staging/media/cnm,wave.yaml | 71 + MAINTAINERS | 9 + drivers/staging/media/Kconfig | 2 + drivers/staging/media/Makefile | 1 + drivers/staging/media/wave5/Kconfig | 12 + drivers/staging/media/wave5/Makefile | 10 + drivers/staging/media/wave5/TODO | 58 + drivers/staging/media/wave5/vdi.c | 260 ++ drivers/staging/media/wave5/vdi.h | 79 + drivers/staging/media/wave5/vpu.c | 353 ++ drivers/staging/media/wave5/vpu.h | 63 + drivers/staging/media/wave5/vpu_dec.c | 1400 +++++++ drivers/staging/media/wave5/vpu_enc.c | 1587 ++++++++ drivers/staging/media/wave5/vpuapi.c | 1096 +++++ drivers/staging/media/wave5/vpuapi.h | 1148 ++++++ drivers/staging/media/wave5/vpuconfig.h | 85 + drivers/staging/media/wave5/vpuerror.h | 455 +++ drivers/staging/media/wave5/wave5-hw.c | 3513 +++++++++++++++++ drivers/staging/media/wave5/wave5.h | 80 + drivers/staging/media/wave5/wave5_regdefine.h | 638 +++ 20 files changed, 10920 insertions(+) create mode 100644 Documentation/devicetree/bindings/staging/media/cnm,wave.yaml create mode 100644 drivers/staging/media/wave5/Kconfig create mode 100644 drivers/staging/media/wave5/Makefile create mode 100644 drivers/staging/media/wave5/TODO create mode 100644 drivers/staging/media/wave5/vdi.c create mode 100644 drivers/staging/media/wave5/vdi.h create mode 100644 drivers/staging/media/wave5/vpu.c create mode 100644 drivers/staging/media/wave5/vpu.h create mode 100644 drivers/staging/media/wave5/vpu_dec.c create mode 100644 drivers/staging/media/wave5/vpu_enc.c create mode 100644 drivers/staging/media/wave5/vpuapi.c create mode 100644 drivers/staging/media/wave5/vpuapi.h create mode 100644 drivers/staging/media/wave5/vpuconfig.h create mode 100644 drivers/staging/media/wave5/vpuerror.h create mode 100644 drivers/staging/media/wave5/wave5-hw.c create mode 100644 drivers/staging/media/wave5/wave5.h create mode 100644 drivers/staging/media/wave5/wave5_regdefine.h -- 2.17.1
