不理它的话，会cancel订单么？

最关心的是，会不会有什么不良影响？？

Linux, 4GB virtual addr space分成俩块，3GB user virtual addr space，和1GB
kernel virtual addr space。
1GB(严格的说好像是896MB)的kernel virtual addr space跟physical mem是one-to-
one map，above 1GB 用page table转换。在kernel mode可以用3GB user virtual
addr space，在user mode不能用1GB kernel virtual addr space (for protection)。 |

发帖数: 1498 | 23 少于896M的话，我觉得所有的 physical address都能被kernel直接访问，都有logical

user virtual addr 和 kernel virtual addr 应该可map到同一physical page吧，如
果kernel 想访问的话。
当user app 执行write或者read时，会通过相应system call 进入kernel mode，这个
时候kernel 应该直接用user app的page table 就可以了吧。我也不确定，我自己理解

1. bgp anycast say 1.1.1.1/24 (a risk here is that best bgp path does not

2. Global DNS always return CDN.com to 1.1.1.1/24 (singe address DNS A
record, or geo-aware multiple A record DNS, whatever)
3. Then for a specific addr, say 1.1.1.1/24 from one ISP, traffic load is
heavier and you want to do load balancing. Then an geo-DNS is placed here (
this one is not the global-zone). It restricted to return query from

标 题: user virtual address space VS kernel virtual address space
发信站: BBS 未名空间站 (Sun Apr 18 17:14:09 2010, 美东)
32-bit machine，virtual address space 4GB，kernel(e.g. linux)会把这4GB，分成
3GB user/1GB kernel。
1GB kernel virtual address space跟物理内存是1-to-1的map。对user virtual addr
做virtual --> physical 转换是也是转到一个kernel virtual addr再到physical
memory。
那这样不是只能用到1GB physical memory，如果有更多
的就用不到了。windows也有这个机制，好奇这样的话不是加内存都没用？大牛给解释
一下啊 |

发帖数: 1567 | 44 多谢多谢。也就是说kernel只能用到up to 1GB physical mem，但是user process可以
用到more than 1GB是吧。
还有一个困惑的地方，比如物理内存少于1GB，这种情况是啥样的？user virtual addr
和 kernel virtual addr会map到同一个physical mem frame? |
