[S390] cio: introduce fcx enabled scsw format

2008-07-14T08:02:07Z

Extend the scsw data structure to the format required by fcx. Also provide helper functions for easier access to fields which are present in both the traditional as well as the modified format. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] Fix a lot of sparse warnings.

2008-04-17T05:47:06Z

Most noteable part of this commit is the new local header file entry.h which contains all the function declarations of functions that get only called from asm code or are arch internal. That way we can avoid extern declarations in C files. This is more or less the same that was done for sparc64. Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] vmur: fix diag14 exceptions with addresses > 2GB.

2007-08-22T11:51:47Z

There are several s390 diagnose calls, which must be executed below the 2GB memory boundary. In order to enforce this, those diagnoses must be compiled into the kernel. Currently diag 14 can be called within the vmur kernel module from addresses above 2GB. This leads to specification exceptions. This patch moves diag10, diag14 and diag210 into the new diag.c file.

[S390] cio: Channel-path configure function.

2007-04-27T14:01:39Z

Add a new attribute to the channel-path sysfs directory through which channel-path configure operations can be triggered. Also listen for hardware events requesting channel-path configure operations and process them accordingly.

[S390] cio/ipl: Clean interface between cio and ipl code.

2007-04-27T14:01:38Z

Clean interface between cio and ipl code, so Peter stops complaining. Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Make ccw_dev_id_is_equal() more robust.

2006-12-04T14:40:54Z

Using memcmp to compare ccw_dev_id implies that the whole structure (incl. padding) has always been completely initialized to sane values. Comparing the structures field by field doesn't make such assumptions. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky

[S390] Reset infrastructure for re-IPL.

2006-12-04T14:40:26Z

In case of re-IPL and diag308 doesn't work we have to reset all devices manually and wait synchronously that each reset finished. This patch adds the necessary infrastucture and the first exploiter of it. Subsystems that need to add a function that needs to be called at re-IPL may register/unregister this function via struct reset_call { struct reset_call *next; void (*fn)(void); }; void register_reset_call(struct reset_call *reset); void unregister_reset_call(struct reset_call *reset); When the registered function get called the context is: - all cpus beside the current one are stopped - all machine checks and interrupts are disabled - prefixing is disabled - a default machine check handler is available for use The registered functions may not take any locks are sleep. For the common I/O layer part of this patch: Introduce a reset_call css_reset that does the following: - clear all subchannels - perform a rchp on all channel paths and wait for the resulting machine checks This replaces the calls to clear_all_subchannels() and cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now uses reipl_find_schid() to determine the subchannel id for a given device id. Also remove cio_reset_channel_paths() and friends since they are not needed anymore. Signed-off-by: Heiko Carstens Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky
