the function __virt_to_phys(unsigned long x) which boils down __pv_stub(x, t, "add", __pv_bits_31_24); __pv_stub macro expands add t, x, 0x8100_0000 apart inserting pointer instruction in .pv_table section, can used patch add instruction during bootup. question regarding constant __pv_bits_31_24. there reason use value 0x8100_0000 it. as per understanding value makes 12 bit immediate encoding field of add instruction 481 hex. @ run time during bootup function __fix_pv_table changes 4c0 hex(assume start of first mem bank @ 0x8000_0000). value 0x8100_0000 common such people have decided use default value during compilation , if different anyway it'll fixed during bootup ? or there different reason unable understand ? in short, because has bits 31 , 24 set, results in appropriate instruction encoding patching msb of offset. remember immediate constants in arm instructions formed 8-bit value rotated 1 of 16 positions in 32-bit word. assembling i

when initializing egl\gles context, use fullscreen. application rendered in half resolution , blitted screen using simple draw. however, performance reasons, possible initialize context in arbritary resolution (for example half full resolution) , have driver\hardware handle blit fullscreen? you can use android hardware scaler this. the way use depends if initialize egl java or native c++ code: // java surfaceview.getholder().setfixedsize(1280, 720); // native int32_t ret = anativewindow_setbuffersgeometry(window, 1280, 720, 0); using hardware scaler gives better rescaling quality, better performance , less energy usage using render target.

i working on while loop stop while variable less 100. have currently, output stops @ 128 - not sure why prints 128 when last output should 64. pointers? import java.util.scanner; public class insectgrowth { public static void main (string [] args) { int numinsects = 0; numinsects = 8; system.out.print(numinsects + " "); while (numinsects < 100) { numinsects = numinsects * 2; system.out.print(numinsects + " "); } system.out.println(); return; } } the last value printed 128 because execute numinsects = numinsects * 2; before system.out.print(numinsects + " "); therefore loop stops when numinsects 64, multiplies 2 before printing, hence why see 128.
