|  | * 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 setup code in xen_ram_init(), | 
|  | *    called via xen_hvm_init_pc(). | 
|  | * | 
|  | * 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) |
