* mt6735: Add an option to multiplex AP and STA on wlan0Diogo Ferreira2017-06-044-8/+13
| | | | | | | | | | | | | This adds CONFIG_MTK_COMBO_AOSP_TETHERING_SUPPORT which, when enabled, allows ap and wlan to co-exist in the same interface, as Android expects. Most of this functionality is also available (albeit not compilable broken) under CFG_TC1_FEATURE but that has larger implications around the radio and usb stack that we do not want to adopt.

* ANDROID: uid_sys_stats: fix negative write bytes.Jin Qian2017-05-231-4/+10
| | | | | | | | | | | | A task can cancel writes made by other tasks. In rare cases, cancelled_write_bytes is larger than write_bytes if the task itself didn't make any write. This doesn't affect total size but may cause confusion when looking at IO usage on individual tasks.

* ANDROID: uid_cputime: add per-uid IO usage accountingJin Qian2017-05-231-16/+233
| | | | | | | | | | | | | | | | | | IO usages are accounted in foreground and background buckets. For each uid, io usage is calculated in two steps. delta = current total of all uid tasks - previus total current bucket += delta Bucket is determined by current uid stat. Userspace writes to /proc/uid_procstat/set <uid> <stat> when uid stat is updated. /proc/uid_io/stats shows IO usage in this format. <uid> <foreground IO> <background IO> Signed-off-by: Jin Qian <jinqian@google.com> Bug: 34198239 Change-Id: I3369e59e063b1e5ee0dfe3804c711d93cb937c0c
