95 | * Calculate ram split, for memory below and above 4G. It's a bit |
96 | * complicated for backward compatibility reasons ... |
97 | * |
98 | * - Traditional split is 3.5G (lowmem = 0xe0000000). This is the |
99 | * default value for max_ram_below_4g now. |
100 | * |
101 | * - Then, to gigabyte align the memory, we move the split to 3G |
102 | * (lowmem = 0xc0000000). But only in case we have to split in |
103 | * the first place, i.e. ram_size is larger than (traditional) |
104 | * lowmem. And for new machine types (gigabyte_align = true) |
105 | * only, for live migration compatibility reasons. |
106 | * |
107 | * - Next the max-ram-below-4g option was added, which allowed to |
108 | * reduce lowmem to a smaller value, to allow a larger PCI I/O |
109 | * window below 4G. qemu doesn't enforce gigabyte alignment here, |
110 | * but prints a warning. |
111 | * |
112 | * - Finally max-ram-below-4g got updated to also allow raising lowmem, |
113 | * so legacy non-PAE guests can get as much memory as possible in |
114 | * the 32bit address space below 4G. |
115 | * |
116 | * - Note that Xen has its own ram setp code in xen_ram_init(), |
117 | * called via xen_hvm_init(). |
118 | * |
119 | * Examples: |
120 | * qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high |
121 | * qemu -M pc -m 4G (new default) -> 3072M low, 1024M high |
122 | * qemu -M pc,max-ram-below-4g=2G -m 4G -> 2048M low, 2048M high |
123 | * qemu -M pc,max-ram-below-4g=4G -m 3968M -> 3968M low (=4G-128M) |
