Subject: [PATCH v2 0/4] media: qcom: flip the switch between Venus and Iris
drivers
As the Venus and Iris drivers are close to the "feature parity" for the
common platforms (SC7280, SM8250), in order to get more attention to
squashing bugs from the Iris driver, flip the switch and default to the
Iris driver if both are enabled. The Iris driver has several
regressions, but hopefully they can be fixed through the development
cycle by the respective team. Also it is better to fail the test than
crash the device (which Venus driver does a lot).
Note: then intention is to land this in 6.21, which might let us to
drop those platforms from the Venus driver in 6.22+.
Testing methodology: fluster test-suite, single-threaded mode, SM8250
device (RB5).
$ ./fluster.py r -j 1 -d GStreamer-H.264-V4L2-Gst1.0 -s -so out-h264.md -ts JVT-AVC_V1
$ ./fluster.py r -j 1 -d GStreamer-H.265-V4L2-Gst1.0 -s -so out-h265.md -ts JCT-VC-HEVC_V1
$ ./fluster.py r -j 1 -d GStreamer-VP9-V4L2-Gst1.0 -s -so out-vp9.md
For H.264:
Only the main set was used on both platforms
On Venus pass 126/135
On Iris pass 78/135
- Fail on Iris, but pass on Venus:
cabac_mot_fld0_full, cabac_mot_mbaff0_full, cabac_mot_picaff0_full,
CAFI1_SVA_C, CAMA1_Sony_C, cama1_vtc_c, cama2_vtc_b, cama3_vtc_b,
CAMACI3_Sony_C, CAMASL3_Sony_B, CAMP_MOT_MBAFF_L30,
CAMP_MOT_MBAFF_L31, CANLMA2_Sony_C, CANLMA3_Sony_C,
cavlc_mot_fld0_full_B, cavlc_mot_mbaff0_full_B,
cavlc_mot_picaff0_full_B, CVCANLMA2_Sony_C, CVFI1_Sony_D, CVFI1_SVA_C,
CVFI2_Sony_H, CVFI2_SVA_C, CVMA1_Sony_D, CVMAPAQP3_Sony_E,
CVMAQP2_Sony_G, CVMAQP3_Sony_D, CVMP_MOT_FLD_L30_B,
CVMP_MOT_FRM_L31_B, CVNLFI1_Sony_C, CVNLFI2_Sony_H, FI1_Sony_E,
MR9_BT_B, Sharp_MP_Field_1_B, Sharp_MP_Field_2_B, Sharp_MP_Field_3_B,
Sharp_MP_PAFF_1r2, Sharp_MP_PAFF_2r
- Fail on Venus, but pass on Iris:
BA3_SVA_C
For Venus several tests crash the firmware or crash the device,
so test-suite was executed with extra:
-sv CABREF3_Sand_D CAMANL1_TOSHIBA_B CAMA1_TOSHIBA_B \
CAMA3_Sand_E CAMANL2_TOSHIBA_B CAMANL3_Sand_E CAPA1_TOSHIBA_B \
CAPAMA3_Sand_F CVMA1_TOSHIBA_B CVMANL1_TOSHIBA_B CVMANL2_TOSHIBA_B \
CVPA1_TOSHIBA_B
For H.265:
Only the main set was used on both platforms
On Venus pass 135/147
On Iris pass 133/147
- Fail on Iris, but pass on Venus:
INITQP_B_Main10_Sony_1, WP_A_MAIN10_Toshiba_3,
WPP_A_ericsson_MAIN10_2, WPP_B_ericsson_MAIN10_2,
WPP_C_ericsson_MAIN10_2, WPP_E_ericsson_MAIN10_2,
WPP_F_ericsson_MAIN10_2
- Fail on Venus, but pass on Iris:
ipcm_A_NEC_3, ipcm_B_NEC_3, ipcm_C_NEC_3, ipcm_D_NEC_3, ipcm_E_NEC_2,
IPRED_B_Nokia_3, VPSSPSPPS_A_MainConcept_1
For VP9 codec:
On Venus pass 174/311
On Iris pass 232/311
- Fail on Venus, but pass on Iris:
