* libion: cleanup loggingMark Salyzyn2018-03-071-5/+5
| | | | | | | | | Get rid of trailing newlines as they just take wasted space. Added a missing strerror(error) expansion for failure to open. Test: compile Bug: 74258013 Change-Id: I04c0038e1ca53d2ffe0a78386744f12874215c19
* libion: Adapt to new ION interfaceLaura Abbott2017-08-091-58/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | 4.12+ kernels have substantially different ION interface. Adapt libion to the new one. In doing so, for sake of clarity, rename ION_IOC_ALLOC to ION_IOC_NEW_ALLOC the to denote new mechanism. An ion_is_legacy() is provided to check whether the kernel supports old ION interface or new. Userspace has the responsibility to use it accordingly. Devices using kernels without the 4.12 ION updates, can continue to use libion as before, and will have no impact. Only devices using libion with 4.12+ kernels (or kernels with backported ION updates) will need to update their users of libion, including gralloc. Test: validated with hikey gralloc, with both old and new kernels Signed-off-by: Laura Abbott <labbott@redhat.com> Signed-off-by: Sumit Semwal <sumit.semwal@linaro.org> [sumits: keep old abi compatibility] Change-Id: I7899af9e812d0cf5e73b443a3f0248118b42a382

* ion.c: add O_CLOEXEC to /dev/ion openNick Kralevich2016-11-291-1/+1
| | | | | Test: device boots and no obvious problems. Change-Id: I0845b79de49b77878adaf6cd14cc506f7586cccb
* libion: open /dev/ion read-onlyJeff Vander Stoep2016-10-211-1/+1
| | | | | | | | | | | /dev/ion driver does not recognize the write operation [1] so open it read-only. [1] http://lxr.free-electrons.com/source/drivers/staging/android/ion/ion.c?v=4.5#L1369 Test: Angler builds and boots Bug: 32120194 Change-Id: I9b26d43ea32cb24426404668701df1f1648d336c
* system/core: preparation to pull back interfaces from android/log.hMark Salyzyn2016-10-201-0/+1
| | | | | | | | | | | | | | | | Point to log/log.h where necessary, define LOG_TAG where necessary. Accept that private/android_logger.h is suitable replacement for log/logger.h and android/log.h. Correct liblog/README Effectively a cleanup and controlled select revert of 'system/core: drop or replace log/logger.h' and 'system/core: Replace log/log.h with android/log.h'.

* system/core Replace cutils/log.h with android/log.hMark Salyzyn2016-09-301-2/+2
| | | | | | | | | | | Should use android/log.h instead of cutils/log.h as a good example to all others. Adjust header order to comply with Android Coding standards. Test: Compile Bug: 26552300 Bug: 31289077 Change-Id: I2c9cbbbd64d8dccf2d44356361d9742e4a9b9031
