mapping memory By [email=dsaks@wittenberg.edu]Dan Saks[/email] Embedded Systems Design (08/11/04, 11:00:00 H EDT) Memory-mapped I/O is something you can do reasonably well in standard C and C++. Device drivers communicate with peripheral devices through device registers. A driver sends commands or data to a device by storing into its device register, or retrieves status or data from a devic...
v2.4.0 pagetable_init() { ... vaddr = __fix_to_virt(__end_of_fixed_addresses - 1) & PMD_MASK; fixrange_init(vaddr, 0, pgd_base); ... } 这里fixrange_init一行应该改成fixrange_init(vaddr, FIXADDR_TOP, pgd_base);,只有这样，后面才可能空出两页 不知我的理解对否?

不知道有沒有大神知道 cat /sys/block/sda/start =3 cat /sys/block/sda/size = 1000 這樣可以知道sda在flash上面的Start Address and End Address 嗎 ?
Linux Memory mapping Purpose The following examples demonstrates how to map a driver allocated buffer from kernel into user space. It has been tested with Linux kernel 2.2.18 and 2.4.0 on Intel (uni processor only) and Alpha platform (COMPAQ Personal Workstation 500au (uni processor), DS20 and ES40 (SMP). Memory mappings The Linux kernel works with different memory mappings. One mapping, calle...
环境：HA双机，主节点上现在有生产，备机刚换过光纤卡，存储（DS4800）那边要把原来到备机的mapping删除，重新做mapping，请教下，在有生产是可以操作吗？谢谢啊 [ 本帖最后由 leikai 于 2010-1-20 19:13 编辑 ]

在Message mapping存在3个比较重要的概念: Value、Context和Queues。一个queue中包含了多个contexts，一个context中包含了多个values。 Value Value最容易理解，就是消息结构中各个字段的值。 Queues Message mapping在运行时通过queues进行的，一个queue中包含了message mapping过程中关于一个字段的所有值，queue又可以分为input queues和result queues。 1）源消息结构中每个字段都对应一个queue； 2）标准functions和用户自...
IP to ASN mapping *** SPECIAL NOTICE *** If you are planning on implementing the use of this service in any software, application, or device PLEASE let us know in advance. We would like to adequately plan for capacity and make sure that we can adequately handle the load. If at all possible, PLEASE use the DNS based service since it is faster and more efficient, particularly for larger deployments...
