electro575Hi all, i'm trying to debug camss driver and imx412 hack for imx 576 camera. Someone have already work on it ? It's for sm6350-mainline. Thanks a lot [19:19]

bryanodonoghueelectro575 cphy or dphy ? [19:41]
electro575msm_csiphy [19:42]
bryanodonoghuedo you have a downstream tree pointer ? [19:43]
electro575i have done this

bryanodonoghue[Jeu Mai 2 17:36:53 2024] camcc_ife_0_clk status stuck at 'off'
there's your first problem
clock isn't on
camcc gdsc is probably not setup right
check the power domains in your dtsi
then check the declarations of the gdsc
in camcc
[19:45]
electro575okey, thanks a lot
i will check this
[19:47]
bryanodonoghuedo you know which version of csid and vfe you are supporting here ? [19:48]
***ao2 has joined #linux-media [19:48]
electro575not really, i have the source code but , ...

[19:48]
bryanodonoghuedo you know a downstream tag for 6350 ?
something like LA.UM.9.16.r1-09800-MANNAR.QSSI12.0
[19:51]
electro575humm, it's not really android [19:52]
bryanodonoghuesimilar tags for the Linux embedded LE.stuff [19:52]
electro575O, sorry, it's not for LE [19:53]
bryanodonoghueLE.UM.4.3.3.r1-01400 [19:53]
electro575postmarketos [19:53]
bryanodonoghueI get you but - what is the source you are working from ? [19:53]
electro575https://github.com/sm6350-mainline/linux/tree/sm6350-6.9-wip-camera
with a beginning work from another person
specially for power domains
https://github.com/sm6350-mainline/linux/blob/sm6350-6.9-wip-camera/drivers/clk/qcom/camcc-sm6350.c
[19:53]
bryanodonoghuefp4 - ping z3ntu
He has a tree I believe
[19:55]
electro575already done, but he doesn't arrived to get data from camera
full media tree
https://debian-facile.org/images/file-Rc0e5e8df8ab6edd1812f4be9187b1ad3
i work with his/her on this camera part
[19:56]
bryanodonoghueright so VFE 1.xx is correct
https://github.com/torvalds/linux/commit/d8d71cb0d37e01307bf8ca485e284e64f46609ea
but IDK that VFE 170 is correct
but if its fp4 then surely the android release tags are public
..
let's offline from IRC about this - sync with Luca
[19:58]
***Moarc has joined #linux-media [20:00]
electro575sorry, what exactly mean "but if its fp4 then surely the android release tags are public" ? [20:01]
bryanodonoghuehttps://code.fairphone.com/projects/fairphone-4/kernel.html
I haven't fetched this yet but the qcom release tags will be there
just need to match the tag to the camera-kernel release and then go through the PHY, IFE, CSID - get the version numbers
[20:02]
z3ntuCLO tag of target tree is LA.QSSI.11.0.R1.11.00.00.668.170.00 I believe [20:03]
bryanodonoghuenice [20:03]
electro575i don't understand :/ lol haaaa [20:03]
***Moarc has quit IRC () [20:04]
z3ntuclo = codelinaro.org where Qualcomm publishes open source code [20:04]
bryanodonoghuewhen qcom releases an android/kernel stack - any android system really - is done on repo
an xml file which points to git repos with git tags
techpacks are releases of say video core or camera core outside of the main android kernel
which contain those tags
parse the repo, find the git tag, find the version of code that matches your silicon
simples
[20:04]
***Moarc has joined #linux-media [20:06]
electro575i will try [20:09]
bryanodonoghueI'll do this
https://code.fairphone.com/projects/fairphone-4/build-instructions.html
[20:09]
electro575to have what ?
this version ?
LA.QSSI.11.0.R1.11.00.00.668.170.00
[20:10]
bryanodonoghuejust for fun :) [20:11]
electro575parse the repo, find the git tag, find the version of code that matches your silicon => What repo exactly ?
this ?
repo init -u ssh://gerrit-public.fairphone.software:29418/manifest -b int/13/fp4
[20:11]
this is this repo ? [20:17]
bryanodonoghueYeah we need to find a tag in that repo
that matches in some way one of the tags here
https://git.codelinaro.org/clo/la/platform/vendor/opensource/camera-kernel.git
that's the CPHY/CSID/IFE version to target
i.e. know which CSIPHY init sequence to use - if we can reuse an upstream CSID/IFE - and get the reg offsets right
[20:18]
electro575ok, i will check [20:21]
