/DragonOS-0.1.2/docs/kernel/core_api/
Dallocate-memory.md3 DragonOS提供了一些用于内存分配的api。您可以使用*kmalloc*来分配小的内存块，也可以使用*alloc_pages*分配连续的2MB大小的内存页面。
7 …，最直接、最简单的分配内存的方式就是，使用`kmalloc()`函数进行分配。并且，出于安全起见，除非内存在分配后一定会被覆盖，且您能确保内存中的脏数据一定不会对程序造成影响，在其余情况下，我们建…
9 您可以通过`kmalloc()`函数分配得到32bytes到1MBytes之间的内存对象。并且，这些内存对象具有以下的性质：
15 当内存空间不再被使用时，那么必须释放他们。若您使用的是`kmalloc()`分配的内存，那么您需要使用`kfree()`释放它。若是使用`alloc_pages()`分配的内存，则需要使用`free…
Dmm-api.md9 ### `void *kmalloc(unsigned long size, gfp_t gfp)`
15   kmalloc用于获取那些小于2M内存页大小的内存对象。可分配的内存对象大小为32bytes~1MBytes. 且分配的内存块大小、起始地址按照2的n次幂进行对齐。（比如，申…
31   获取小块的内存，并将其清零。其余功能与kmalloc相同。
50   该函数用于释放通过kmalloc申请的内存。如果`address`为NULL，则函数被调用后，无事发生。
52   请不要通过这个函数释放那些不是从`kmalloc()`或`kzalloc()`申请的内存，否则将会导致系统崩溃。
