| | | | | | | | | | | | | | | | | | | | | | | | | | With the kernel parameter 'vmalloc=<size>' the size of the vmalloc area can be specified. This can be used to increase or decrease the size of the area. Works in the same way as on some other architectures. This can be useful for features which make excessive use of vmalloc and wouldn't work otherwise. The default sizes remain unchanged: 96MB for 31 bit kernels and 1GB for 64 bit kernels.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

* | KVM: s390: use hrtimer for clock wakeup from idle - v2Christian Borntraeger2009-06-10
|/ | | | | | | | | | | | | | | | | This patch reworks the s390 clock comparator wakeup to hrtimer. The clock comparator is a per-cpu value that is compared against the TOD clock. If ckc <= TOD an external interrupt 1004 is triggered. Since the clock comparator and the TOD clock have a much higher resolution than jiffies we should use hrtimers to trigger the wakeup. This speeds up guest nanosleep for small values. Since hrtimers callbacks run in hard-irq context, I added a tasklet to do the actual work with enabled interrupts.

* [S390] /proc/stat idle field for idle cpusMartin Schwidefsky2009-04-23
| | | | | | | | | | | | | The cpu idle field in the output of /proc/stat is too small for cpus that have been idle for more than a tick. Add the architecture hook arch_idle_time that allows to add the not accounted idle time of a sleeping cpu without waking the cpu. The s390 implementation of arch_idle_time uses the already existing s390_idle_data per_cpu variable to find the sleep time of a neighboring idle cpu.

* [S390] add read_persistent_clockMartin Schwidefsky2009-04-14
| | | | | | | | | Add a read_persistent_clock function that does not just return 0.

The architecture states, that bit 0-7 of STIDP returns all zero, and if STIDP is executed in a virtual machine, the VM operating system will replace bits 0-7 with FF. KVM should not use FE to distinguish z/VM from KVM for interested guests. The proper way to detect the hypervisor is the STSI (Store System Information) instruction, which return information about the hypervisors via function code 3, selector1=2, selector2=2. This patch changes the detection routine of Linux to use STSI instead of STIDP. This detection is earlier than bootmem, we have to use a static buffer. Since STSI expects a 4kb block (4kb aligned) this patch also changes the init.data alignment for s390. As this section will be freed during boot, this should be no problem. Patch is tested with LPAR, z/VM, KVM on LPAR, and KVM under z/VM. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | To support High Performance FICON, the DASD device driver has to translate I/O requests into the new transport mode control words (TCW) instead of the traditional (command mode) CCW requests.

| * | [S390] dasd: add large volume supportStefan Weinhuber2009-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dasd device driver will now support ECKD devices with more then 65520 cylinders. In the traditional ECKD adressing scheme each track is addressed by a 16-bit cylinder and 16-bit head number. The new addressing scheme makes use of the fact that the actual number of heads is never larger then 15, so 12 bits of the head number can be redefined to be part of the cylinder address.
