Hi, Kalyan Thota

It seems this change caused some drm problems with the Android build.
I tested with one Android build that based on the ACK android-mainline
kernel[1], and there are the message printed like
01-01 06:51:50.541 504 504 E :
[drm:_dpu_rm_check_lm_and_get_connected_blks] [dpu error]failed to get
dspp on lm 0

01-01 06:51:50.570 504 504 E :

01-01 06:51:50.579 504 504 E :

mixers
01-01 06:51:50.588 504 504 E : [drm:dpu_rm_reserve]
[dpu error]failed to reserve hw resources: -119
For details, please check the link here: https://termbin.com/31lc

If I revert this commit, then the problem will be gone.
Could you please help check if there is any problem with this commit?

Thanks for your email. Can you help share some details.
1) https://termbin.com/31lc , I am unable to open the link in my office network, can you copy the logs in a text file and share with me.
2) Which DPU version are you trying from the catalogue, can you share the version ?
3) The patch will fail the atomic_check, if the commit is requesting for a CTM, and there are no dspp HW blocks to reserve. Can you check in your catalogue entry that you have sufficient dspp resources to LM

Thanks,
Kalyan
