797862 - reduce ONCRPC, memalloc, IdleService, and Gecko CC/GCC log spam

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia, defect)

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

Currently, logcat output is dominated by extremely verbose logging from a few modules.  Do we actually need all this logging?  Writing to the kernel ring buffer is not free to begin with, and it makes it very difficult to see actual useful logcat messages.  Even if we need all this logging, it would be nice to make it significantly less verbose (again, ring buffer is not free, and is finite in size anyway; useful stuff gets purged very quickly).

Examples:

D/memalloc(  105): /dev/pmem: Allocated buffer base:0x4ab00000 size:307200 offset:4972544 fd:159
D/memalloc(  502): /dev/pmem: Mapped buffer base:0x44100000 size:5279744 offset:4972544 fd:23
D/memalloc(  105): /dev/pmem: Allocated buffer base:0x4ab00000 size:307200 offset:2822144 fd:158
