gram_find_free()

Find a free memory space from a guest system's RAM/ROM regions

Synopsis:

#include <qvm/gasp.h>

static uint64_t gram_find_free(struct guest_system *const gsp,
                               uint64_t const size,
                               uint64_t const align,
                               unsigned const flags)

Arguments:

gsp: A pointer to the system where we want to find the free space.
size: The number of bytes of free space that we need.
align: The requested alignment of the space.
flags: A GRAM_HINT_* combination

Library:

Provided by qvm; no external library is required.

Description:

This function calls gram_reserve() on the region it returns, so you don't need to do that.

Returns:

The location of the free space, or QSL_NO_LOCATION if no space is available.
