| |
Hi people,
I'm surprised there is a hard 2GB phys memory limit on Alpha although it seems the kernel (2.2.9 btw) uses 64bit pointers..
Is the test in arch/alpha/kernel/setup.c only a safety measure and I could safely remove it or are there architecture reasons for it (like the phys + virt/proc = 4GB for x86)? I thought there won't be such oddities on a 64bit system.
If some internal 32bit/paging table issue is the culprit here, would the high mem patch for decent x86 kernels address this problem too? (Currently 4GB phys on Alpha would suffice for me).
Any advice/comment is highly appreciated, Michael.
