memory - Is there any way to inspect kernel space in GDB? -

memory - Is there any way to inspect kernel space in GDB? - i may have more fundamental misunderstanding here, outline everything: i wanted gain improve understanding of how programs laid out in memory. starting here went , made simple programs , opened them in gdb see things laid in more practical sense: 0x0 - 0x08048000 = ?? 0x08048000 = start .text section 0x08048000 = plt 0x08048300 = _start 0x08048400 = main 0x08048480 = other functions 0x0804a000 = got 0x0804a020 = start .data section 0x0804a028 = start .bss section (random offset) 0x0804b008 = start heap ... 0xf7?????? = start memory mapping section 0xf7e50000 = #included library function definitions 0xf7ff0000 = linux dynamic loader (random offset) 0xffffd010 = top of stack (grows negatively) (random offset) i understand lot of these addresses subject change, helped me visualize assigning numbers things. anyway, in next image presented in source above, there's block dedicated kernel space @ top of program...

c++ - Why does this recursive function crash? -

c++ - Why does this recursive function crash? - int g(int n) { int x = g(n - 1); if (x > 0) { homecoming x + 1; } else { homecoming 1; } } my guess has first line of function... i'm not sure why case. if function said this: int g(int n) { homecoming g(n - 1); } then not expect work, instead maintain recursing until run out of stack space , programme crashes. putting recursion before exit status in function, doing this. you should rewrite function performs exit test before calling g() again. c++ crash segmentation-fault

embedded - can I change "delay until" granularity on cortex-m4? -

embedded - can I change "delay until" granularity on cortex-m4? - i'm scheduling loop "delay until" clause on stm32f4 discovery board, , when increment frequency, thing stop respecting time constraint. after digging, under impression it's scheduler granularity not task. 1 of signs when go slow time respected, , faster go, more bonkers go. tardiness seems discrete, falling on scheduling frequency limit. here test code: task body pwm onperiod : time_span; offperiod : time_span; period : time_span; next_start : time := clock; pwm_on : boolean := true; begin loop period := microseconds (1_000_000) / pwmfrequency; onperiod := period / 3; offperiod := 2 * period / 3; if (pwm_on) off (pattern (next_led)); pwm_on := false; next_start := next_start + offperiod; else on (pattern (next_led)); ...
