129 * Calculate ram split, for memory below and above 4G. It's a bit
130 * complicated for backward compatibility reasons ...
132 * - Traditional split is 3.5G (lowmem = 0xe0000000). This is the
133 * default value for max_ram_below_4g now.
135 * - Then, to gigabyte align the memory, we move the split to 3G
136 * (lowmem = 0xc0000000). But only in case we have to split in
137 * the first place, i.e. ram_size is larger than (traditional)
138 * lowmem. And for new machine types (gigabyte_align = true)
139 * only, for live migration compatibility reasons.
141 * - Next the max-ram-below-4g option was added, which allowed to
142 * reduce lowmem to a smaller value, to allow a larger PCI I/O
143 * window below 4G. qemu doesn't enforce gigabyte alignment here,
144 * but prints a warning.
146 * - Finally max-ram-below-4g got updated to also allow raising lowmem,
147 * so legacy non-PAE guests can get as much memory as possible in
148 * the 32bit address space below 4G.
150 * - Note that Xen has its own ram setup code in xen_ram_init(),
151 * called via xen_hvm_init_pc().
154 * qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high
155 * qemu -M pc -m 4G (new default) -> 3072M low, 1024M high
156 * qemu -M pc,max-ram-below-4g=2G -m 4G -> 2048M low, 2048M high
157 * qemu -M pc,max-ram-below-4g=4G -m 3968M -> 3968M low (=4G-128M)
