Would like to know if anything is pending form our end as we want to get the patches mainlined?

Thanks,

I'd like to get a clearer picture on this

[   90.535909] qcom-camss ac6a000.camss: VFE HW Version = 2.0.1
[   90.545756] qcom-camss ac6a000.camss: CSIPHY 3PH HW Version = 0x40010000
[   90.546358] qcom-camss ac6a000.camss: CSID HW Version = 2.0.1
[   90.546365] qcom-camss ac6a000.camss: csid_link_setup: Enabled CSID virtual channels mask 0x1 [   90.547675] qcom-camss ac6a000.camss: csid_link_setup: Enabled CSID virtual channels mask 0x0

Using the IMX577 sensor on the RB5 we get his pretty odd virtual channels mask.

If userspace is sending this in, the question I have is why. Surely with a sensor that doesn't have a VC there should be no impact on user-space.

Hey Bryan,

what media-ctl commands are you using? I can't recreate this on my side. I am using this set of commands to test (with the default imx577 driver without any multiple virtual channels outputs) and am getting only the first message (virtual channels mask 0x1):

media-ctl --reset
media-ctl -v -d /dev/media0 -V '"imx577 '22-001a'":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy2":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'

yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0


Thanks,

Milen

Its a dev_dbg() so "#define DEBUG 1" in drivers/media/platform/qcom/camss/camss-csid.c

Yes, I enabled the dev_dbg(). I just see only one message with regards to the channels mask. Just this one:

[   90.546365] qcom-camss ac6a000.camss: csid_link_setup: Enabled CSID virtual channels mask 0x1

so I wonder if you're testing with a different set of media-ctl/yavta commands.


Regards,

Milen
