Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This series adds support for multi hardware decode into mtk-vcodec, by first adding use
of_platform_populate to manage each hardware information: interrupt, clock, register
bases and power. Secondly add core work queue to deal with core hardware message,
at the same time, add msg queue for different hardware share messages. Lastly, the
architecture of different specs are not the same, using specs type to separate them.

This series has been tested with both MT8183 and MT8173. Decoding was working for both chips.

Patches 1~3 rewrite get register bases and power on/off interface.

Patches 4 build decoder pm file to module.

Patches 5 add to support 8192.

Patch 6 add component framework to support multi hardware.

Patch 7 separate video encoder and decoder document

Patches 8-17 add interfaces to support core hardware.
---
Changes compared with v7:
- add new patch 4 to build decoder pm file as module
- add new patch 5 to support 8192
- fix comments for patch 6/17
- change some logic for using work queue instead of create thread for core hardware decode for patch 10/17
- using work queue for hardware decode instead of create thread for patch 13/17
- add returen value for patch 14/17
- fix yaml check fail 15/17

Changes compared with v6:
- Use of_platform_populate to manage multi hardware, not component framework for patch 4/15
- Re-write dtsi document for hardware architecture changed for patch 13/15 -The dtsi will write like below in patch 13/15:

Changes compared with v5:
- Add decoder hardware block diagram for patch 13/15

Changes compared with v4:
- Fix comments for patch 4/15

>> + ret = mtk_vcodec_init_master(dev);
>> + if (ret < 0)
>> + goto err_component_match;

Fix platform_set_drvdata.
- Fix build error for patch 9/15
- Add depend patch in case of error header file for patch 13/15

Changes compared with v3:
- Fix return value for patch 1/15
- Fix comments for patch 4/15
> Looking up "mediatek,mtk-vcodec-core" to determine if it uses component framwork sounds like...
Add prameter in pdata, for all platform will use compoent after mt8183

>> + ret = mtk_vcodec_init_master(dev);
>> + if (ret < 0)

> + Has asked the same question in [1]. Why it removes the

Must call component_master_add_with_match after platform_set_drvdata for component architecture.
- Fix yaml files check fail for patch 5/15
- Fix yaml file check fail for patch 14/15

Changes compared with v1:
- Fix many comments for patch 3/14
- Remove unnecessary code for patch 4/14
- Using enum mtk_vdec_hw_count instead of magic numbers for patch 6/14
- Reconstructed get/put lat buffer for lat and core hardware for patch 7/14
- Using yaml format to instead of txt file for patch 12/14
