Rpi 4 & 5 Libcamera & Mmap permission issue on Android 14

[jan at radicalsystems.co.za]

Hi Libcamera Fundis!

 

Having a problem capturing an image on Android 14 (& 13).

Tombstone looks like this:

 

06-03 15:13:03.880 308 578 I DMABUFHEAPS: Using : Non-legacy ION heaps

06-03 15:13:03.880 308 578 I [minigbm:gbm_mesa_internals.cpp(233)]: Found

.... lots of Permission denied!

06-03 15:13:11.282 308 359 E libcamera: ERROR Buffer

06-03 15:13:12.008 308 579 E libcamera: ERROR Camera camera.cpp:675 Camera

06-03 15:13:12.008 308 579 E libcamera: ERROR HAL camera_device.cpp:390
'/base/axi/pcie at 120000/rp1/i2c at 88000/imx708 at 1a': Failed to acquire the
camera

06-03 15:13:12.008 308 579 E libcamera: ERROR HAL camera3_hal.cpp:81 Failed

06-03 15:13:12.008 308 579 E libcamera: FATAL HAL
generic_frame_buffer_allocator.cpp:106 gralloc_open() failed: -87

 

MLKIT Streaming & analyzing works until trying to capture an image the above
happens.

The various Android versions for Rpi5 I could find gave the same issue.

I tried Emteria, AOSP & LineageOS 13 & 14

Android built from Raspberry Vanilla and even replacing with later libcamera
had the same issue.

 

I'm not sure if this is purely a configuration problem, wrt to policies or
permissions or specifically to the RPi's architecture.

 

Please help, I can rebuild and test.

I have tried the latest code pulled into RaspVanilla, but had the same
issue.

 

Regards
