[S390] qdio: new qdio driver.

2008-07-17T15:22:10Z

List of major changes: - split qdio driver into several files - seperation of thin interrupt code - improved handling for multiple thin interrupt devices - inbound and outbound processing now always runs in tasklet context - significant less tasklet schedules per interrupt needed - merged qebsm with non-qebsm handling - cleanup qdio interface and added kerneldoc - coding style Reviewed-by: Cornelia Huck Reviewed-by: Utz Bacher Reviewed-by: Ursula Braun Signed-off-by: Jan Glauber Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] Remove P390 support.

2008-07-14T08:02:25Z

Most likely it is broken anyway because of the changes in memory detection. Since we can't test it and there are probably better ways that using a P390 card, remove support for it. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] Move memory detection code to own file.

2008-07-14T08:02:17Z

Move memory detection code to own file and also simplify it. Also add an interface which can be called at any time to get the current memory layout. This interface is needed by our kernel internal system dumper. Cc: Peter Oberparleiter Cc: Michael Holzheu Cc: Frank Munzert Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] Extra Kernel Parameters via VMPARM

2008-07-14T08:02:14Z

Now it is possible to specify additional kernel parameters on the IPL command line using the IPL PARM option. If the Linux system is already running, the new reipl sysfs attribute 'parm' can be used to change kernel parameters for the next reboot. Examples: IPL C PARM dasd=1234 root=/dev/dasda1 IPL 1234 PARM savesys=mylnxnss echo "init=/bin/bash" > /sys/firmware/reipl/ccw/parm Signed-off-by: Hendrik Brueckner Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] System z large page support.

2008-04-30T11:38:47Z

This adds hugetlbfs support on System z, using both hardware large page support if available and software large page emulation on older hardware. Shared (large) page tables are implemented in software emulation mode, by using page->index of the first tail page from a compound large page to store page table information.

[S390] Convert machine feature detection code to C.

2008-04-30T11:38:47Z

From: Heiko Carstens From: Carsten Otte This lets us use defines for the magic bits in machine flags instead of using plain numbers all over the place. In addition on newer machines features/facilities are indicated by the result of the stfl instruction. So we use these bits instead of trying to execute new instructions and check wether we get an exception or not. Also the mvpg instruction is always available when in zArch mode, whereas the idte instruction is only available in zArch mode. This results in some minor optimizations.

s390: KVM guest: detect when running on kvm

2008-04-27T09:00:50Z

This patch adds functionality to detect if the kernel runs under the KVM hypervisor. A macro MACHINE_IS_KVM is exported for device drivers. This allows drivers to skip device detection if the systems runs non-virtualized. We also define a preferred console to avoid having the ttyS0, which is a line mode only console.

[S390] zfcpdump support.

2007-04-27T14:01:44Z

s390 machines provide hardware support for creating Linux dumps on SCSI disks. For creating a dump a special purpose dump Linux is used. The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux. This patch exports memory and registers of the crashed Linux to userspace via a debugfs file. For more information refer to Documentation/s390/zfcpdump.txt, which is included in this patch.
