The original SeaBIOS code used the RamSize variable, that was used by
|
|
|
0a122b |
SeaBIOS for the size of RAM below 4GB, not for all RAM. When copied to
|
|
|
0a122b |
QEMU, the code was changed to use the full RAM size, and this broke the
|
|
|
0a122b |
build_srat() code that handles the PCI hole.
|
|
|
0a122b |
|
|
|
0a122b |
Change build_srat() to use ram_size_below_4g instead of ram_size, to
|
|
|
0a122b |
restore the original behavior from SeaBIOS.
