[S390] Add config option for z196 code generation.

2010-10-25T14:10:15Z

Add a kernel config option for the IBM zEnterprise 196. This will produce faster code on newer compilers using the -march=z196 option. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] standardize Kbuild rules

2010-10-25T14:10:14Z

Introducing this Kbuild file allow us to: make arch/s390/ And thus building all the core part of s390. Same as on other architectures. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line

2010-08-03T12:09:45Z

It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

[S390] vdso: add missing vdso_install target

2010-05-17T08:00:16Z

Add missing vdso_install target to install the unstripped vdso images into $(MODLIB)/vdso/. These files are helpful when containing additional debugging information. Signed-off-by: Hendrik Brueckner Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] add support for compressed kernels

2010-02-26T21:37:33Z

Add the "bzImage" compile target and the necessary code to generate compressed kernel images. The old style uncompressed "image" target is preserved, a simple make will build them both. Signed-off-by: Martin Schwidefsky

[S390] hibernation: merge files and move to kernel/

2009-09-11T08:29:45Z

Merge the nearly empty C files and move everything from power/ to kernel/. That way the files are easier to handle. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] s390: hibernation support for s390

2009-06-16T08:31:22Z

This patch introduces the hibernation backend support to the s390 architecture. Now it is possible to suspend a mainframe Linux guest using the following command: echo disk > /sys/power/state Signed-off-by: Hans-Joachim Picht Signed-off-by: Martin Schwidefsky

[S390] Add processor type march=z10 and a processor type safety check.

2008-12-25T12:39:12Z

This patch adds the code generation option for IBM System z10 and adds a check in head[31,64].S to prevents the execution of a kernel compiled for a new processor type on an old machine. Signed-off-by: Martin Schwidefsky

KVM: s390: arch backend for the kvm kernel module

2008-04-27T09:00:42Z

This patch contains the port of Qumranet's kvm kernel module to IBM zSeries (aka s390x, mainframe) architecture. It uses the mainframe's virtualization instruction SIE to run virtual machines with up to 64 virtual CPUs each. This port is only usable on 64bit host kernels, and can only run 64bit guest kernels. However, running 31bit applications in guest userspace is possible. The following source files are introduced by this patch arch/s390/kvm/kvm-s390.c similar to arch/x86/kvm/x86.c, this implements all arch callbacks for kvm. __vcpu_run calls back into sie64a to enter the guest machine context arch/s390/kvm/sie64a.S assembler function sie64a, which enters guest context via SIE, and switches world before and after that include/asm-s390/kvm_host.h contains all vital data structures needed to run virtual machines on the mainframe include/asm-s390/kvm.h defines kvm_regs and friends for user access to guest register content arch/s390/kvm/gaccess.h functions similar to uaccess to access guest memory arch/s390/kvm/kvm-s390.h header file for kvm-s390 internals, extended by later patches Acked-by: Martin Schwidefsky Signed-off-by: Christian Borntraeger Signed-off-by: Heiko Carstens Signed-off-by: Carsten Otte Signed-off-by: Avi Kivity
