| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the atags used by kexec are fixed to the ones originally used to boot the kernel. This is less than ideal as changing the commandline, initrd and other options would be a useful feature. This patch exports the atags used for the current kernel to userspace through an "atags" file in procfs. The presence of the file is controlled by its own Kconfig option and cleans up several ifdef blocks into a separate file. The tags for the new kernel are assumed to be at a fixed location before the kernel image itself. The location of the tags used to boot the original kernel is unimportant and no longer saved.

* | [ARM] 4660/3: at91: allow selecting UART for early kernel messagesGuennadi Liakhovetski2008-02-04
|/ | | | | | | | | | | | | Currently early kernel messages, i.e., those from uncompression, go to the debugging UART. And if it is enabled in the platform configuration, but not initialized by the bootloader, the machine hangs, waiting for UART status change. Besides, having those messages on another UART - typically the console UART - may be preferrable. This patch allows selecting the UART in kernel configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CAPACITY_LEVEL stuff defines various levels of charge; however, what is the difference between them? What differentiates between HIGH and NORMAL, LOW and CRITICAL, etc? As it appears that these are fairly arbitrary, we end up making such policy decisions in the kernel (or in hardware). This is the sort of decision that should be made in userspace, not in the kernel. If the hardware does not support _CAPACITY and it cannot be easily calculated, then perhaps the driver should register a custom CAPACITY_LEVEL attribute; however, userspace should not become accustomed to looking for such a thing, and we should certainly not encourage drivers to provide CAPACITY_LEVEL stubs. The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The OLPC battery driver is the only driver making use of this, so it's removed from there as well.

| * | svc: Move the sockaddr information to svc_xprtTom Tucker2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the transport sockaddr to the svc_xprt structure. Convenience functions are added to set and get the local and remote addresses of a transport from the transport provider as well as determine the length of a sockaddr. A transport is responsible for setting the xpt_local and xpt_remote addresses in the svc_xprt structure as part of transport creation and xpo_accept processing. This cannot be done in a generic way and in fact varies between TCP, UDP and RDMA. A set of xpo_ functions (e.g. getlocalname, getremotename) could have been added but this would have resulted in additional caching and copying of the addresses around. Note that the xpt_local address should also be set on listening endpoints; for TCP/RDMA this is done as part of endpoint creation. For connected transports like TCP and RDMA, the addresses never change and can be set once and copied into the rqstp structure for each request. For UDP, however, the local and remote addresses may change for each request. In this case, the address information is obtained from the UDP recvmsg info and copied into the rqstp structure from there. A svc_xprt_local_port function was also added that returns the local port given a transport. This is used by svc_create_xprt when returning the port associated with a newly created transport, and later when creating a generic find transport service to check if a service is already listening on a given port.

This involves close because these lists are walked by svcs when closing all their transports. So I combined the moving of these lists to svc_xprt with making close transport independent. The svc_force_sock_close has been changed to svc_close_all and takes a list as an argument. This removes some svc internals knowledge from the svcs. This code races with module removal and transport addition. Thanks to Simon Holm Thøgersen for a compile fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The svc_create_xprt function is a transport independent version of the svc_makesock function. Since transport instance creation contains transport dependent and independent components, add an xpo_create transport function. The transport implementation of this function allocates the memory for the endpoint, implements the transport dependent initialization logic, and calls svc_xprt_init to initialize the transport independent field (svc_xprt) in it's data structure.

Since some transports don't use sockets, this logic now uses a flag bit (SK_LISTENER) to identify listening endpoints. A transport function (xpo_accept) allows each transport to define its own accept processing. A transport's initialization logic is reponsible for setting the SK_LISTENER bit. I didn't see any way to do this in transport independent logic since the passive side of a UDP connection doesn't listen and always recv's. In the svc_recv function, if the SK_LISTENER bit is set, the transport xpo_accept function is called to handle accept processing. Note that all functions are defined even if they don't make sense for a given transport. For example, accept doesn't mean anything for UDP. The function is defined anyway and bug checks if called. The UDP transport should never set the SK_LISTENER bit.

These checks have been broken out into separate statements to make the code easier to read.
