89 | * Calculate ram split, for memory below and above 4G. It's a bit | |
90 | * complicated for backward compatibility reasons ... | |
91 | * | |
92 | * - Traditional split is 3.5G (lowmem = 0xe0000000). This is the | |
93 | * default value for max_ram_below_4g now. | |
94 | * | |
95 | * - Then, to gigabyte align the memory, we move the split to 3G | |
96 | * (lowmem = 0xc0000000). But only in case we have to split in | |
97 | * the first place, i.e. ram_size is larger than (traditional) | |
98 | * lowmem. And for new machine types (gigabyte_align = true) | |
99 | * only, for live migration compatibility reasons. | |
100 | * | |
101 | * - Next the max-ram-below-4g option was added, which allowed to | |
102 | * reduce lowmem to a smaller value, to allow a larger PCI I/O | |
103 | * window below 4G. qemu doesn't enforce gigabyte alignment here, | |
104 | * but prints a warning. | |
105 | * | |
106 | * - Finally max-ram-below-4g got updated to also allow raising lowmem, | |
107 | * so legacy non-PAE guests can get as much memory as possible in | |
108 | * the 32bit address space below 4G. | |
109 | * | |
110 | * - Note that Xen has its own ram setp code in xen_ram_init(), | |
111 | * called via xen_hvm_init(). | |
112 | * | |
113 | * Examples: | |
114 | * qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high | |
115 | * qemu -M pc -m 4G (new default) -> 3072M low, 1024M high | |
116 | * qemu -M pc,max-ram-below-4g=2G -m 4G -> 2048M low, 2048M high | |
117 | * qemu -M pc,max-ram-below-4g=4G -m 3968M -> 3968M low (=4G-128M) | |
