src/runtime/mem.go
// OS-specific implementations that handle errors, while the interface boundary // implements cross-OS functionality, like updating runtime accounting. // sysAlloc transitions an OS-chosen region of memory from None to Ready. // More specifically, it obtains a large chunk of zeroed memory from the // operating system, typically on the order of a hundred kilobytes

src/runtime/HACKING.md
There are three mechanisms for allocating unmanaged memory: * sysAlloc obtains memory directly from the OS. This comes in whole multiples of the system page size, but it can be freed with sysFree. * persistentalloc combines multiple smaller allocations into a single sysAlloc to avoid fragmentation. However, there is no way to free persistentalloced objects (hence the name).
