* 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)
