[DEV] First step of reserve engineering libcamera (Work in progress)
I'm working on reserve engineering libcamera for Tattoo, based on libcamera2 by NCommander. Thanks to nopy
for many help.
HTC have changed a lot in their kernel, and left LOTS of useless or temporary codes not to be cleaned up. Right now, camera codes in the kernel are very clean and tidy and mainly ported from AOSP-donut kernel. Interfaces of /dev/msm_camera/control0, config0, and frame0 are successfully generated. As you know, HTC kernel implemented the /dev/msm_camera/msm_camera0 interface to communicate with requests from user space. I'm not sure why HTC did such a hack. The reason why I ported camera codes from AOSP-donut relies on the fact that most of camera working ROMs for other headsets like Dream or Sapphire did this, even if these ROMs are powered by 2.6.32 or even 2.6.34 kernels.
I've sticked to HTC camera driver in the kernel. Please check out my github

If anyone is interested in hacking for Tattoo, just let know. I'll invite you to cooperate with us.
