question about read clock API in ARM
Hello, I'm newbie in L4 and now i'm trying to find out how to get system clock info. My test environment is QEMU, ARM realview EB. In fiasco kernel, there is a function to read system's clock Clock::read_count(){ return Io::read<Mword>(SYS_24MHZ); } then how can I use this in l4re application? Is there any related API in l4re? Thanks in advance, david
You can get the timer counter from l4_kernel_info_t in the kernel interface page in the file l4sys/include/__kip-32bit.h in the L4Re programming environment. Cheng On Sun, Aug 7, 2011 at 12:29 AM, 박찬주 <beastworld@gmail.com> wrote:
