Inquiry Regarding /dev/kgsl-3d0 Availability on Kernel 6.1 #12
Description
Dear Qualcomm Support Team,
My service is currently invoking an EGL function early during the boot process. However, on kernel 6.1, I observed that the /dev/kgsl-3d0 node becomes available later than expected, causing the function to fail with the following error:
01-01 00:06:52.253 627 690 E Adreno-GSL: <ioctl_kgsl_driver_entry:1000>: open(/dev/kgsl-3d0) failed: errno 2. No such file or directory
On the previous kernel (5.4), this node was available much earlier. Based on my investigation, the timing of node creation seems to depend on ueventd and devtmpfs. I suspect that devtmpfs might be disabled or its behavior changed in kernel 6.1, which could explain the delay compared to 5.4.
Could you kindly review this issue and share your insights or recommendations?
Thank you for your support.
Sincerely,
Trieu Huynh
