Subject: [PATCH] linux-user: map lower in address space
|
|
|
|
While trying to compile Java I can into situations where there was simply
|
|
no virtual address space left for a 32-bit guest to take. For example when
|
|
Java tried to allocate 1GB of heap.
|
|
|
|
Part of the problem is that we're starting to map things at 0x40000000.
|
|
This is a bit high. Taking that number down would give us a lot of free
|
|
virtual address space which means we'd be able to squeeze more stuff in.
