Signed-off-by: Benjamin Gaignard Reviewed-by: Rob Herring Reviewed-by: Philipp Zabel I need to edit the yaml file to add support the imx8mm, but it doesn't appear that this series has gone anywhere. I know there is still some waiting on the vpu-blk-ctrl driver, but it seems like the 8mq could split the codecs out using syscon in place of the blk-ctrl until that driver is available. If that doesn't work, I might have to introduce a separate yaml file for mini which could be somehow merged with the 8mq in the future. I am just not sure which way to go right now. To summarize Lucas a have a branch here: https://git.pengutronix.de/cgit/lst/linux/log/?h=imx8mq-vpu-blk-ctrl where he try to enable blk-ctrl for imx6mq, it is working for G1 but not for G2.

Sorry for putting a spoke in the wheel after many iterations of the series. We just discussed a way forward on how to handle the clocks and resets provided by the blkctl block on i.MX8MM and later and it seems there is a consensus on trying to provide virtual power domains from a blkctl driver, controlling clocks and resets for the devices in the power domain. I would like to avoid introducing yet another way of handling the blkctl and thus would like to align the i.MX8MQ VPU blkctl with what we are planning to do on the later chip generations. CC'ing Jacky Bai and Peng Fan from NXP, as they were going to give this virtual power domain thing a shot. Hey guys, I may I have miss them but I haven't see patches about power domain for IMX8MQ VPU control block ? Is it something that you still plan to do ?

If they don't (and are testing on non-hantro HW), then it won't work, thus defeating the purpose of the HW independent decoder API. Since hantro is widely used, and if there is no other way to do this beside explitely setting this control, then perhaps this should be part of the standard HEVC API. Non-hantro drivers that do not need this can just skip it.

[PATCH v10 8/9] media: hantro: Introduce G2/HEVC decoder
Implement all the logic to get G2 hardware decoding HEVC frames. It supports up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or the scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Computing the needed value is complex and requires information from the stream that only the userland knows so let it provide the correct value to the driver.

[PATCH v10 0/9] Add HANTRO G2/HEVC decoder support for IMX8MQ
The IMX8MQ got two VPUs but until now only G1 has been enabled. This series aim to add the second VPU (aka G2) and provide basic HEVC decoding support. To be able to decode HEVC it is needed to add/update some of the structures in the uapi. In addition of them one HANTRO dedicated control is required to inform the driver of the number of bits to skip at the beginning of the slice header. The hardware require to allocate few auxiliary buffers to store the references frame or tile size data. The driver has been tested with fluster test suite stream. For example with this command: ./fluster.py run -ts JCT-VC-HEVC_V1 -d GStreamer-H.265-V4L2SL-Gst1.0 version 10: - Shorter version of the previous series without ctrl block patches and no DT modifications. The scope of this series is limited to HEVC support. version 9: - Corrections in commits messages. - Define the dedicated control in hevc-controls.h - Add note in documentation. - Change max value of the dedicated control. - Rebased on media_tree/master branch. version 8: - Add reviewed-by and ack-by tags - Fix the warnings reported by kernel test robot - Only patch 9 (adding dedicated control), patch 11 (HEVC support) and patch 13 (DT changes) are still missing of review/ack tag. version 7: - Remove 'q' from syscon phandle name to make usable for iMX8MM too. Update the bindings documentation. - Add review/ack tags. - Rebase on top of media_tree/master - Be more accurate when computing the size of the memory needed motion vectors. - Explain why the all clocks need to set in the both DT node. version 6: - fix the errors reported by kernel test robot version 5: - use syscon instead of VPU reset driver. - Do not break kernel/DT backward compatibility. - Add documentation for dedicated Hantro control. - Fix the remarks done by Ezequeil (typo, comments, unused function) - Run v4l2-compliance without errors (see below). - Do not add field to distinguish version, check postproc reg instead version 4: - Split the changes in hevc controls in 2 commits to make them easier to review. - Change hantro_codec_ops run() prototype to return errors - Hantro v4l2 dedicated control is now only an integer - rebase on top of VPU reset changes posted here: https://www.spinics.net/lists/arm-kernel/msg878440.html - Various fix from previous remarks - Limit the modifications in API to what the driver needs version 3: - Fix typo in Hantro v4l2 dedicated control - Add documentation for the new structures and fields - Rebased on top of media_tree for-linus-5.12-rc1 tag version 2: - remove all change related to scaling - squash commits to a coherent split - be more verbose about the added fields - fix the comments done by Ezequiel about dma_alloc_coherent usage - fix Dan's comments about control copy, reverse the test logic in tile_buffer_reallocate, rework some goto and return cases. - be more verbose about why I change the bindings - remove all sign-off expect mime since it is confusing - remove useless clocks in VPUs nodes Benjamin Gaignard (9): media: hevc: Add fields and flags for hevc PPS media: hevc: Add decode params control media: hantro: change hantro_codec_ops run prototype to return errors media: hantro: Define HEVC codec profiles and supported features media: hantro: Only use postproc when post processed formats are defined media: uapi: Add a control for HANTRO driver media: hantro: handle V4L2_PIX_FMT_HEVC_SLICE control media: hantro: Introduce G2/HEVC decoder media: hantro: IMX8M: add variant for G2/HEVC codec .../userspace-api/media/drivers/hantro.rst| 19 + .../userspace-api/media/drivers/index.rst | 1 + .../media/v4l/ext-ctrls-codec.rst | 108 +++- .../media/v4l/vidioc-queryctrl.rst| 6 + drivers/media/v4l2-core/v4l2-ctrls.c | 28 +- drivers/staging/media/hantro/Makefile | 2 + drivers/staging/media/hantro/hantro.h | 13 +- drivers/staging/media/hantro/hantro_drv.c | 99 ++- .../staging/media/hantro/hantro_g1_h264_dec.c | 10 +- .../media/hantro/hantro_g1_mpeg2_dec.c| 4 +- .../staging/media/hantro/hantro_g1_vp8_dec.c | 6 +- .../staging/media/hantro/hantro_g2_hevc_dec.c | 587 ++ drivers/staging/media/hantro/hantro_g2_regs.h | 198 ++ .../staging/media/hantro/hantro_h1_jpeg_enc.c | 4 +- drivers/staging/media/hantro/hantro_hevc.c| 327 ++ drivers/staging/media/hantro/hantro_hw.h | 69 +- .../staging/media/hantro/hantro_postproc.c| 14 + drivers/staging/media/hantro/hantro_v4l2.c| 5 +- drivers/staging/media/hantro/imx8m_vpu_hw.c | 74 ++- .../media/hantro/rk3399_vpu_hw_jpeg_enc.c | 4 +- .../media/hantro/rk3399_vpu_hw_mpeg2_dec.c| 4 +- .../media/hantro/rk3399_vpu_hw_vp8_dec.c | 6 +- drivers/staging/media/sunxi/cedrus/cedrus.c | 6 + drivers/staging/media/sunxi/cedrus/cedrus.h | 1 + .../staging/media/sunxi/cedr

Get hevc part merged could allow me to continue to add features like scaling lists, compressed reference buffers and 10-bit supports. Makes sense to me! Great ! If the latest version match your expectations how would you like to processed ? Can you merged patches 4 to 12 ? or should I resend them in a new shorted series ?

[PATCH v9 13/13] arm64: dts: imx8mq: Add node to G2 hardware
Split the VPU node in two: one for G1 and one for G2 since they are different hardware blocks. Add syscon for the hardware control block. Remove the reg-names property that is useless. Each VPU node only needs one interrupt. Change G2 assigned clock to match the specification. In both nodes all the clocks need to be assigned to make sure that the control block will be correctly clocked even if only one device node is enabled.

[PATCH v9 11/13] media: hantro: Introduce G2/HEVC decoder
Implement all the logic to get G2 hardware decoding HEVC frames. It supports up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or the scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Computing the needed value is complex and requires information from the stream that only the userland knows so let it provide the correct value to the driver.

[PATCH v9 02/13] dt-bindings: media: nxp, imx8mq-vpu: Update the bindings for G2 support
Introducing the G2 hevc video decoder requires modifications of the bindings to allow one node per VPU. VPUs share one hardware control block which is provided as a phandle on a syscon. Each node has now one reg and one interrupt. Add a compatible for G2 hardware block: nxp,imx8mq-vpu-g2. To be compatible with older DT the driver is still capable to use the 'ctrl' reg-name even if it is deprecated now.

Implement all the logic to get G2 hardware decoding HEVC frames. It support up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Compute the needed value is complex and require information from the stream that only the userland knows so let it provide the correct value to the driver.

Introducing G2 hevc video decoder lead to modify the bindings to allow to get one node per VPUs. VPUs share one hardware control block which is provided as a phandle on an syscon. Each node got now one reg and one interrupt. Add a compatible for G2 hardware block: nxp,imx8mq-vpu-g2.

Each VPU node only need one interrupt. Change G2 assigned clock to match to the specifications. In the both nodes all the clocks need to assigned to make sure that control block will be correctly clocked even if only one device node is enabled.

[PATCH v7 11/13] media: hantro: Introduce G2/HEVC decoder
Implement all the logic to get G2 hardware decoding HEVC frames. It support up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Compute the needed value is complex and require information from the stream that only the userland knows so let it provide the correct value to the driver.

[PATCH v7 02/13] dt-bindings: media: nxp, imx8mq-vpu: Update the bindings for G2 support
Introducing G2 hevc video decoder lead to modify the bindings to allow to get one node per VPUs. VPUs share one hardware control block which is provided as a phandle on an syscon.

[PATCH v6 11/13] media: hantro: Introduce G2/HEVC decoder
Implement all the logic to get G2 hardware decoding HEVC frames. It support up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Compute the needed value is complex and require information from the stream that only the userland knows so let it provide the correct value to the driver.

[PATCH v6 03/13] media: hantro: Use syscon instead of 'ctrl' register
In order to be able to share the control hardware block between VPUs use a syscon instead a ioremap it in the driver. To keep the compatibility with older DT if 'nxp,imx8mq-vpu-ctrl' phandle is not found look at 'ctrl' reg-name. With the method it becomes useless to provide a list of register names so remove it.

[PATCH v6 02/13] dt-bindings: media: nxp, imx8mq-vpu: Update the bindings for G2 support
Introducing G2 hevc video decoder lead to modify the bindings to allow to get one node per VPUs. VPUs share one hardware control block which is provided as a phandle on an syscon. Each node got now one reg and one interrupt. Add a compatible for G2 hardware block: nxp,imx8mq-vpu-g2. To be compatible with older DT the driver is still capable to use 'ctrl' reg-name even if it is deprecated now.

[PATCH v5 11/13] media: hantro: Introduce G2/HEVC decoder
Implement all the logic to get G2 hardware decoding HEVC frames. It support up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Compute the needed value is complex and require information from the stream that only the userland knows so let it provide the correct value to the driver.

[PATCH v5 02/13] dt-bindings: media: nxp, imx8mq-vpu: Update the bindings for G2 support
Introducing G2 hevc video decoder lead to modify the bindings to allow to get one node per VPUs. VPUs share one hardware control block which is provided as a phandle on an syscon. Each node got now one reg and one interrupt. Add a compatible for G2 hardware block: nxp,imx8mq-vpu-g2. To be compatible with older DT the driver is still capable to use 'ctrl' reg-name even if it is deprecated now.

They are all part of the control block and of the reset process for this hardware that why I put them here. I guess it is border line :-) I'm pushing back to keep the reset control framework focused on controlling reset lines. Every side effect (such as the asymmetric clock ungating) in a random driver makes it harder to reason about behaviour at the API level, and to review patches for hardware I am not familiar with. In order to be able to add the second VPU (for HECV decoding) it will be more handy if the both VPU drivers instance don't have to share the control block registers. This lead to implement it as an independ reset driver and to change the VPU driver to use it. Why not switch to a syscon regmap for the control block? That should also allow to keep backwards compatibility with the old binding with minimal effort. I will give a try in this direction. Thank you. Please note that this series break the compatibility between the DTB and kernel. This break is limited to IMX8MQ SoC and is done when the driver is still in staging directory. I know in this case we are pretty sure there are no users of this binding except for a staging driver, but it would still be nice to keep support for the deprecated binding, to avoid the requirement of updating kernel and DT in lock-step. If I want to use a syscon (or a reset) the driver must not ioremap the "ctrl" registers. It means that "ctrl" has to be removed from the driver requested reg-names (imx8mq_reg_names[]). Doing that break the kernel/DT compatibility. Somehow syscon and "ctrl" are exclusive. The way the driver is set up currently, yes. You could add a bit of platform specific probe code, though, that would set up the regmap either by calling syscon_regmap_lookup_by_phandle(); for the new binding, or, if the phandle is not available, fall back to platform_get_resource_byname(..., "ctrl"); devm_ioremap_resource(); devm_regmap_init_mmio(); for the old binding. The actual codec .reset and variant .runtime_resume ops could be identical then. I made it works with syscon and your proposal. The next version of the patches will be without reset and won't break DT compatibility.

[PATCH v3 0/5] Reset driver for IMX8MQ VPU hardware block
The two VPUs inside IMX8MQ share the same control block which can be see as a reset hardware block. In order to be able to add the second VPU (for HECV decoding) it will be more handy if the both VPU drivers instance don't have to share the control block registers. This lead to implement it as an independ reset driver and to change the VPU driver to use it. Please note that this series break the compatibility between the DTB and kernel.

Document IMX8MQ VPU bindings to add the phandle to the reset driver. Provide an independent reset driver allow to the both VPUs to share their control/reset hardware block. The reset driver replace what was previously done be using the 'ctrl' registers inside the driver. This breaks the compatibility between DTB and kernel but the driver is still in staging directory and limited to IMX8MQ SoC.
