How to change the THREAD_SIZE for i.MX6DL Linux BSP

[yuuki]

Dear all,

We run the Linux BSP on i.MX6DL_SABRE
Linux BSP: L3.14.28-1.0.0

Would you tell me how to change the THREAD_SIZE?

We changed it as follows

arch/arm/include/asm/thread_info.h

=====================================

#define THREAD_SIZE_ORDER      2
#define THREAD_SIZE            16384
#define THREAD_START_SP        (THREAD_SIZE - 16)

=====================================

Furthermore, is there the point that should be changed?

Best Regards,
Yuuki

Hi Yuuki

this defines linux stack size and usually no need to change it. It is described

in common linux resources

c - How does the kernel know what is the current thread? - Stack Overflow 

c - Debug stack overruns in kernel modules - Stack Overflow 

also one can check linux/arch/arm/include/asm/thread_info.h :

#define THREAD_SIZE_ORDER    1
#define THREAD_SIZE        (PAGE_SIZE << THREAD_SIZE_ORDER) 

Best regards
igor
