--- Comment #22 from Vladimir Kondratyev <[email protected]> --- (In reply to Konstantin Belousov from comment #20) > 1. Why vbox needs to access userspace > 2. If the item 1 is legitimate, why doesn't vbox use copyin(9) KPI. <CITE> For historic reasons, VirutalBox kernel code needs to access user-level code because the complete virtual memory of the guest is mapped on the host side and on 32-bit hosts we have the 1G limitation in the kernel part of the address space (3G for userland, 1G for kernel, kernel starts at 0xC0000000). And we don't want to limit guests on 32-bit hosts to 1GB RAM. <\CITE> https://www.virtualbox.org/ticket/13820 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-emulation To unsubscribe, send any mail to "[email protected]"
