// 0: Disables all debug code that hasn't been enabled otherwise.
// 1: Enables some lightweight debug code.
// 2: Enables more debug code. Will impact performance.

// general kernel debugging
// Enables kernel ASSERT()s and various checks, locking primitives aren't
// benaphore-style.
#define KDEBUG KDEBUG_LEVEL_2
// Enable this to get support for kernel breakpoints.
#define KERNEL_BREAKPOINTS 0
// block/file cache
// Enables debugger commands.
#define DEBUG_BLOCK_CACHE KDEBUG_LEVEL_1
// Enables checks that non-dirty blocks really aren't changed. Seriously
// degrades performance when the block cache is used heavily.
#define BLOCK_CACHE_DEBUG_CHANGED KDEBUG_LEVEL_2
// Enables a global list of file maps and related debugger commands.
#define DEBUG_FILE_MAP KDEBUG_LEVEL_1
// heap
// Initialize newly allocated memory with something non zero.
#define PARANOID_KERNEL_MALLOC KDEBUG_LEVEL_2
// Check for double free, and fill freed memory with 0xdeadbeef.
#define PARANOID_KERNEL_FREE KDEBUG_LEVEL_2
// Validate sanity of the heap after each operation (slow!).
#define PARANOID_HEAP_VALIDATION 0
// Store size, thread and team info at the end of each allocation block.
// Enables the "allocations*" debugger commands.
#define KERNEL_HEAP_LEAK_CHECK 0
// interrupts
// Adds statistics and unhandled counter per interrupts. Enables the "ints"
// debugger command.

// semaphores
// Enables tracking of the last threads that acquired/released a semaphore.
#define DEBUG_SEM_LAST_ACQUIRER KDEBUG_LEVEL_1
// SMP
// Enables spinlock caller debugging. When acquiring a spinlock twice on a
// non-SMP machine, this will give a clue who locked it the first time.
// Furthermore (also on SMP machines) the "spinlock" debugger command will be
// available.
#define DEBUG_SPINLOCKS KDEBUG_LEVEL_2

// Enables the vm_page::queue, i.e. it is tracked which queue the page should
// be in.
