[S390] split/move machine check handler code

2009-03-26T14:24:10+00:00

Split machine check handler code and move it to cio and kernel code where it belongs to. No functional change. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] ftrace: dont trace machine check handler

2009-03-26T14:24:09+00:00

The ftrace code is currently not reentrant, so we better don't trace our machine check handler. Machine checks are handled like NMIs on s390. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[PATCH] improve idle cputime accounting

2008-12-31T14:11:48+00:00

Distinguish the cputime of the idle process where idle is actually using cpu cycles from the cputime where idle is sleeping on an enabled wait psw. The former is accounted as system time, the later as idle time. Signed-off-by: Martin Schwidefsky

[S390] stp support.

Add support for clock synchronization with the server time protocol. Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Cleanup crw interface.

2008-07-14T08:02:06+00:00

Eliminate the need for the machine check handler to call into the common I/O layer directly by introducing an interface to register handlers for crws per rsc. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

KVM: s390: handle machine checks when guest is running

2008-06-06T18:08:26+00:00

The low-level interrupt handler on s390 checks for _TIF_WORK_INT and exits the guest context, if work is pending. TIF_WORK_INT is defined as_TIF_SIGPENDING | _TIF_NEED_RESCHED | _TIF_MCCK_PENDING. Currently the sie loop checks for signals and reschedule, but it does not check for machine checks. That means that we exit the guest context if a machine check is pending, but we do not handle the machine check.

[S390] cio: replace subchannel evaluation queue with bitmap

2007-04-27T14:01:40+00:00

Use a bitmap for indicating which subchannels require evaluation instead of allocating memory for each evaluation request. This approach reduces memory consumption during recovery in case of massive evaluation request occurrence and removes the need for memory allocation failure handling.
