hi, all: i want to add a function in xen. in the function i need to call the "printk" to display the values of some variables. i found the definition of printk() in file "xen-3.1.0-src\xen\include\xen\lib.h ": extern void printk(const char *format, ...) __attribute__ ((format (printf, 1, 2))); who can tell me the location of printk()? thanks in advance. 2008...

This patch fixes size of ttbcr register (TCR_EL1 in case of AArch64) and it''s programming considering size in case of context switch. Currently ttbcr is defined as 32b register but for AArch64 TCR_EL1 size is 64b.

Hi Folks, Please read the below post - I keep having to fix up printk-related build warnings, usually because I miss them on x86_64, then someone builds on ia64 or ppc, etc and e-mails me. This is trivial to avoid though - we keep making the same mistake: { u64 block; printk("block: %llu\n", block); } That code above will generate a warning similar to:...
