I am trying to find out the run time memory allocated for Graphics subsystem on a android device leaving bitpmaps and resources aside.
I understand that Below factors contribute to RAM of a Android device keeping Graphics subsystem in mind a) Views b) Caching[Texture cache, gradient cache etc and optimisation [ GPU rendering / 2D hw pipeline c) Surfaces d) Memroy allocated by Graphics vendor like 3d graphics and openGl operations. To determine this,i took help of Android dumpstate log which gives librank,procrank output and gfx service logs. so When i add 1) PSS total of below excerpts from librank 92671K /dev/pvrsrvkm 715K /system/lib/libskia.so 359K /system/vendor/lib/egl/ libGLESv1******.so 343K /system/vendor/lib/egl/ libGLESv2_ 315K /system/lib/libEGL.so 251K /system/lib/libgui.so 227K /system/lib/libhwui.so 131K /system/lib/libui.so 103K /system/lib/egl/ libGLES_android.so 99K /system/vendor/lib/ libIMGegl.so 88K /system/lib/ libsurfaceflinger.so 87K /system/lib/ libpixelflinger.so 3K /dev/ashmem/SurfaceFlinger 2) and Adding caches size printed of all the apps under GFXService dump Example , launcher app shows...below details Caches: Current memory usage / total memory usage (bytes): TextureCache 2559640 / 25165824 LayerCache 1703936 / 16777216 GradientCache 0 / 524288 ................... ........................ .................... Total memory usage: 2670600 bytes, 2.55 MB Quesitons: 1) By adding 1 + 2 i conclude that i have got memory occupied in RAM because of Entire Graphics subsystem ? 2) What kind of mem allcoatins go into /dev/pvrsrvkm and /dev/ashmem/ SurfaceFlinger 3) is there any other better method to calculate Kindly answer this question as soon as possible -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
