Kernel configuration.
◆ CONFIG_INTERRUPT_STACK_PAGES
| #define CONFIG_INTERRUPT_STACK_PAGES 1 |
Interrupt stack configuration.
The CONFIG_INTERRUPT_STACK_PAGES constant defines the amount of pages that are allocated for the per-CPU interrupt, exception and doubleFault stacks.
The interrupt stack can be much much smaller than regular kernel stacks as all interrupt handlers should be as short as possible and allocate as little memory as possible to reduce the amount of time while preemptions are disabled.

◆ CONFIG_MAX_KERNEL_STACK_PAGES
| #define CONFIG_MAX_KERNEL_STACK_PAGES 100 |
Kernel stack configuration.
The CONFIG_MAX_KERNEL_STACK_PAGES constant defines the maximum amount of pages that are allowed to be allocated for a threads kernel stack, the kernel stack is used while the thread is in kernel space and NOT handling an exception/interrupt.
Definition at line 32 of file config.h.
◆ CONFIG_MAX_USER_STACK_PAGES
| #define CONFIG_MAX_USER_STACK_PAGES 100 |
User stack configuration.
The CONFIG_MAX_USER_STACK_PAGES constant defines the maximum amount of pages that are allowed to be allocated for a threads user stack, the user stack is used while the thread is in user space.

Cache hot threshold configuration.
The CONFIG_CACHE_HOT_THRESHOLD constant defines the threshold below which a time duration is considered "cache
hot", meaning that the data is likely still in the CPU cache.
