* s390: add assembler include path for vx-insn.hMartin Schwidefsky2016-09-061-0/+2
| | | | | | | | | | | | | | | With git commit 0eab11c7e0d30de14a15ccd8269eef238321a8e1 "s390/vx: allow to include vx-insn.h with .include" and an older gcc we get errors like this: {standard input}:6: Error: can't open asm/vx-insn.h for reading: No such file or directory arch/s390/kernel/fpu.c:57: Error: Unrecognized opcode: `vstm' To solve this issue simply add the path to arch/s390/include to all assembler runs.

* s390/facilities: add helper tool to generate facility listsHeiko Carstens2015-12-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Modifying the architecture level set facility lists was always very error prone. Given the numbering of the facility bits within the Principles of Operation, where the most significant bit number is 0, it happened a lot of times that wrong bits were set or cleared. Therefore this patch adds a tool "gen_facilities" which generates include/generated/facilites.h. The definition of the bits to be set is contained within arch/s390/include/asm/facilities_src.h and can be easily extended to e.g. also generate such lists for the KVM module. The generated file looks like this: #define FACILITIES_ALS _AC(0xc1006450f0040000,UL) #define FACILITIES_ALS_DWORDS 1 The facility bits defined in this patch match 1:1 to the current masks that can be found in head.S. That is if the tool gets executed with -march=z990 then the generated masks will equal the masks in head.S for CONFIG_MARCH_Z990.

* s390: remove 31 bit supportHeiko Carstens2015-03-251-15/+1
| | | | | | | | | | | | | | | | | | | Remove the 31 bit support in order to reduce maintenance cost and effectively remove dead code. Since a couple of years there is no distribution left that comes with a 31 bit kernel. The 31 bit kernel also has been broken since more than a year before anybody noticed. In addition I added a removal warning to the kernel shown at ipl for 5 minutes: a960062e5826 ("s390: add 31 bit warning message") which let everybody know about the plan to remove 31 bit code. We didn't get any response. Given that the last 31 bit only machine was introduced in 1999 let's remove the code. Anybody with 31 bit user space code can still use the compat mode.

* s390/ftrace: hotpatch support for function tracingHeiko Carstens2015-01-291-0/+10
| | | | | | | | | | | | | | | Make use of gcc's hotpatch support to generate better code for ftrace function tracing. The generated code now contains only a six byte nop in each function prologue instead of a 24 byte code block which will be runtime patched to support function tracing. With the new code generation the runtime overhead for supporting function tracing is close to zero, while the original code did show a significant performance impact.

* s390: pass march flag to assembly files as wellHeiko Carstens2014-09-091-7/+10
| | | | | | | | | | | | | Currently the march flag gets only passed to C files, but not to assembler files. This means that we can't add new instructions like e.g. aghik to asm files, since the assembler doesn't know of the new instructions if the appropriate march flag isn't specified. So also pass the march flag when compiling assembler files as well. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | Add a new Kconfig choice group which allows to configure how gcc should tune the generated code (via -mtune option).

* s390: always set -march compiler optionHeiko Carstens2013-10-241-7/+7
| | | | | | | | | | | | | | | | | Currently we only set the -march compiler option if the kbuild system figured out that the compiler actually supports the selected architecture (cc-option test). In result this means that no -march compiler option is set when an unsupported cpu architecture of the current compiler is selected. The kernel compile will afterwards succeed but with the default architecture instead of the (unsupported) selected one. Change this behaviour, so compiles will fail if the compiler does not support the selected cpu architecture.

* s390: use -fPIC for module compileMartin Schwidefsky2013-01-121-2/+2
| | | | | | | | | The xfs module uses a lot of tracepoint, with TRACEPOINTS=y and a few debugging options the GOT table of the xfs module will get bigger than 4K.

* s390: add zEC12 code generation supportHeiko Carstens2012-11-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Allow to generate code that only runs on zEC12 machines. Also add a check which prevents the kernel to run on machines which do not have any of the following new facilities installed: - (48) decimal-floating-point zoned-conversion - (49) execution-hint - (49) load-and-trap - (49) miscellaneous-instruction-extensions - (49) processor-assist - (50) constrained transactional-execution - (73) transactional-execution 48, 49, 50 and 73 are the bit numbers of the facility indications for each of the required facilities. Note that we assume that user-space gets compiled with the same compiler options, therefore we also test for a dfp facility even if the kernel doesn't make use of it.

* [S390] cleanup entry point definitionChristian Borntraeger2012-01-181-1/+0
| | | | | | | | | | | | | | | The vmlinux file for s390 contains a currently unused entry point, which is specified in two different locations: the linker script and the makefile. As it happens both definitions are different and the linker file is broken (_start does not exist) and the makefile specifies an entry point which makes no sense (the SALIPL loader entry point). So lets get rid of one definition (the makefile) and use the entry point of all other ipl methods (0x10000 -> startup) to be consistent.

* | kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command lineSam Ravnborg2010-08-031-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <schwidefsky@de.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

For example, it is possible to get usage data for physical and virtual cpus. In order to provide this information to user space programs, I implemented a new virtual Linux file system named 's390_hypfs' using the Linux 2.6 libfs framework. The name 's390_hypfs' stands for 'S390 Hypervisor Filesystem'. All the accounting information is put into different virtual files which can be accessed from user space. All data is represented as ASCII strings. When the file system is mounted the accounting information is retrieved and a file system tree is created with the attribute files containing the cpu information. The content of the files remains unchanged until a new update is made. An update can be triggered from user space through writing 'something' into a special purpose update file. We create the following directory structure: <mount-point>/ update cpus/ <cpu-id> type mgmtime <cpu-id> ... hyp/ type systems/ <lpar-name> cpus/ <cpu-id> type mgmtime cputime onlinetime <cpu-id> ... <lpar-name> cpus/ ... - update: File to trigger update - cpus/: Directory for all physical cpus - cpus/<cpu-id>/: Directory for one physical cpu. - cpus/<cpu-id>/type: Type name of physical zSeries cpu. - cpus/<cpu-id>/mgmtime: Physical-LPAR-management time in microseconds. - hyp/: Directory for hypervisor information - hyp/type: Typ of hypervisor (currently only 'LPAR Hypervisor') - systems/: Directory for all LPARs - systems/<lpar-name>/: Directory for one LPAR. - systems/<lpar-name>/cpus/<cpu-id>/: Directory for the virtual cpus - systems/<lpar-name>/cpus/<cpu-id>/type: Typ of cpu. - systems/<lpar-name>/cpus/<cpu-id>/mgmtime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the hypervisor and was not provided to the LPAR (LPAR overhead). - systems/<lpar-name>/cpus/<cpu-id>/cputime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the LPAR. - systems/<lpar-name>/cpus/<cpu-id>/onlinetime: Accumulated number of microseconds during which the logical CPU has been online. As mount point for the filesystem /sys/hypervisor/s390 is created. The update process is triggered when writing 'something' into the 'update' file at the top level hypfs directory. You can do this e.g. with 'echo 1 > update'. During the update the whole directory structure is deleted and built up again.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
