Adding debugfs common interface to support decode and encode, using echo command to control debug log level and getting useful information for each instance. patch 1 add dbgfs common interface. patch 2~5 support decode. patch 6~7 support encode --- changed with v2: - using pr_debug and dev_dbg instead of pr_info for patch 2. - fix word fail: informatiaoin -> information for patch 3. - used to print each instance format information for patch 5. changed with v1: - add new patch 4 and 5. - using cmd 'cat vdec' to show debug information instead of pr_info directly. --- Yunfei Dong (7): media: mediatek: vcodec: Add debugfs interface to get debug information media: mediatek: vcodec: Add debug params to control different log level media: mediatek: vcodec: Add a debugfs file to get different useful information media: mediatek: vcodec: Get each context resolution information media: mediatek: vcodec: Get each instance format type media: mediatek: vcodec: Change dbgfs interface to support encode media: mediatek: vcodec: Add encode to support dbgfs .../media/platform/mediatek/vcodec/Makefile | 6 + .../mediatek/vcodec/mtk_vcodec_dbgfs.c | 196 ++++++++++++++++++ .../mediatek/vcodec/mtk_vcodec_dbgfs.h | 72 +++++++ .../mediatek/vcodec/mtk_vcodec_dec_drv.c | 4 + .../platform/mediatek/vcodec/mtk_vcodec_drv.h | 4 + .../mediatek/vcodec/mtk_vcodec_enc_drv.c | 2 + .../mediatek/vcodec/mtk_vcodec_util.c | 8 + .../mediatek/vcodec/mtk_vcodec_util.h | 26 ++- 8 files changed, 315 insertions(+), 3 deletions(-) create mode 100644 drivers/media/platform/mediatek/vcodec/mtk_vcodec_dbgfs.c create mode 100644 drivers/media/platform/mediatek/vcodec/mtk_vcodec_dbgfs.h
