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