It is found on the J721S2 SoC, JH7100 SoC, and ssd202d SoC. etc. But the current test report is based on J721S2 SoC and pre-silicon FPGA. The driver currently supports V4L2_PIX_FMT_HEVC and V4L2_PIX_FMT_H264. This driver has so far been tested on the J721S2 EVM board and pre-silicon FPGA. Testing on the J721S2 EVM board in combination with the GStreamer v4l2 good plugin shows the decoder is working correctly, it has been tested with H264 & HEVC video clips with multiple different dimensions (4k, 1080p, 720p, 540p, 360p, 270p) and various lengths. Additionally, Fluster conformance tests have been run for both supported codecs. The encoder can encode various videos but still has some issues causing it to fail occassionally.

Use this format instead of implicitly converting the bottom and right attributes to width and height attributes. * Return an error upon reading the sequence header while STREAMON * Squash the VDI and the VPUAPI layer commits as they had circular dependencies changes since v9: * Move from staging to the media directory * Move coda driver to sub-directory * Fixes: * Use platform_get_irq instead of platform_get_resource to fetch the IRQ * General cleanups: * Add missing error messages to error conditions * Improve messages/variable names/comments, align parameter names across the driver * Use macros instead of magic numbers in multiple occassions * Reduce code duplication in multiple places * Fix whitespace, newline and tab alignment issues * Remove unused struct fields & commented out code * Convert signed integers to unsigned if signed is not necessary * Convert int/unsigned int to s32/u32, when the variable is assigned to the return of a register read or provided as a parameter for a register write (and vice versa) * Fix incorrect bitwise operators where logical operators are appropriate * Multiple smaller changes * Generalization: * Add new helper file providing generalized routines for vpu-dec & vpu-enc * Generalize luma & chroma table size calculation and stride calculation * Resource cleanup and error handling: * Add error handling to all calls with ignored return codes * Handle DMA resource cleanup properly * Fix insufficient instance cleanup while opening dec/enc changes since v8: * add 'wave5' to DEV_NAME * update to support Multi-stream * update to support loop test/dynamic resolution change * remove unnecessary memset, g_volatile, old version option changes since v7: * update v4l2-compliance test report * fix build error on linux-kernel 5.18.0-rc4 changes since v6: * update TODO file * get sram info from device tree changes since v5: * support NV12/NV21 pixelformat for encoder and decoder * handle adnormal exit and EOS changes since v4: * refactor functions in wave5-hw and fix bug reported by Daniel Palmer * rename functions and variables to better names * change variable types such as replacing s32 with u32 and int with bool * as appropriate changes since v3: * Fixing all issues commented by Dan Carpenter * Change file names to have wave5- prefix * In wave5_vpu_probe, enable the clocks before reading registers, as * commented from Daniel Palmer * Add more to the TODO list, changes since v2: Main fixes includes: * change the yaml and dirver code to support up to 4 clks (instead of * one) * fix Kconfig format * remove unneeded cast, * change var types * change var names, func names * checkpatch fixes changes since v1: Fix changes due to comments from Ezequiel and Dan Carpenter. Main fixes inclueds: * move all files to one dir 'wave5' * replace private error codes with standard error codes * fix extra spaces * various checkpatch fixes * replace private 'DPRINTK' macro with standard 'dev_err/dbg ..' * fix error handling * add more possible fixes to the TODO file Nas Chung (3): media: chips-media: wave5: Add vpuapi layer media: chips-media: wave5: Add the v4l2 layer media: chips-media: wave5: Add TODO file Robert Beckett (2): dt-bindings: media: wave5: add yaml devicetree bindings media: chips-media: wave5: Add wave5 driver to maintainers file Sebastian Fricke (1): media: platform: chips-media: Move Coda to separate folder .../devicetree/bindings/cnm,wave5.yml | 72 + MAINTAINERS | 11 +- drivers/media/platform/chips-media/Kconfig | 18 +- drivers/media/platform/chips-media/Makefile | 6 +- .../media/platform/chips-media/coda/Kconfig | 18 + .../media/platform/chips-media/coda/Makefile | 6 + .../chips-media/{ => coda}/coda-bit.c | 0 .../chips-media/{ => coda}/coda-common.c | 0 .../chips-media/{ => coda}/coda-gdi.c | 0 .../chips-media/{ => coda}/coda-h264.c | 0 .../chips-media/{ => coda}/coda-jpeg.c | 0 .../chips-media/{ => coda}/coda-mpeg2.c | 0 .../chips-media/{ => coda}/coda-mpeg4.c | 0 .../platform/chips-media/{ => coda}/coda.h | 0 .../chips-media/{ => coda}/coda_regs.h | 0 .../chips-media/{ => coda}/imx-vdoa.c | 0 .../chips-media/{ => coda}/imx-vdoa.h | 0 .../platform/chips-media/{ => coda}/trace.h | 0 .../media/platform/chips-media/wave5/Kconfig | 12 + .../media/platform/chips-media/wave5/Makefile | 10 + drivers/media/platform/chips-media/wave5/TODO | 18 + .../platform/chips-media/wave5/wave5-helper.c | 175 + .../platform/chips-media/wave5/wave5-helper.h | 28 + .../platform/chips-media/wave5/wave5-hw.c | 3359 +++++++++++++++++ .../chips-media/wave5/wave5-regdefine.h | 743 ++++ .../platform/chips-media/wave5/wave5-vdi.c | 245 ++ .../platform/chips-media/wave5/wave5-vdi.h | 67 + .../chips-media/wave5/wave5-vpu-dec.c | 1429 +++++++ .../chips-media/wave5/wave5-vpu-enc.c | 1746 +++++++++ .../platform/chips-media/wave5/wave5-vpu.c | 362 ++ .../platform/chips-media/wave5/wave5-vpu.h | 72 + .../platform/chips-media/wave5/wave5-vpuapi.c | 1040 +++++ .../platform/chips-media/wave5/wave5-vpuapi.h | 1136 ++++++ .../chips-media/wave5/wave5-vpuconfig.h | 90 + .../chips-media/wave5/wave5-vpuerror.h | 454 +++ .../media/platform/chips-media/wave5/wave5.h | 94 + 36 files changed, 11190 insertions(+), 21 deletions(-) create mode 100644 Documentation/devicetree/bindings/cnm,wave5.yml create mode 100644 drivers/media/platform/chips-media/coda/Kconfig create mode 100644 drivers/media/platform/chips-media/coda/Makefile rename drivers/media/platform/chips-media/{ => coda}/coda-bit.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-common.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-gdi.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-h264.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-jpeg.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-mpeg2.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda-mpeg4.c (100%) rename drivers/media/platform/chips-media/{ => coda}/coda.h (100%) rename drivers/media/platform/chips-media/{ => coda}/coda_regs.h (100%) rename drivers/media/platform/chips-media/{ => coda}/imx-vdoa.c (100%) rename drivers/media/platform/chips-media/{ => coda}/imx-vdoa.h (100%) rename drivers/media/platform/chips-media/{ => coda}/trace.h (100%) create mode 100644 drivers/media/platform/chips-media/wave5/Kconfig create mode 100644 drivers/media/platform/chips-media/wave5/Makefile create mode 100644 drivers/media/platform/chips-media/wave5/TODO create mode 100644 drivers/media/platform/chips-media/wave5/wave5-helper.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-helper.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-hw.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-regdefine.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vdi.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vdi.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpu-dec.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpu-enc.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpu.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpu.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpuapi.c create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpuapi.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpuconfig.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5-vpuerror.h create mode 100644 drivers/media/platform/chips-media/wave5/wave5.h
