* powerpc: Enable asymmetric SMT scheduling on POWER7Michael Neuling2010-06-092-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The POWER7 core has dynamic SMT mode switching which is controlled by the hypervisor. There are 3 SMT modes: SMT1 uses thread 0 SMT2 uses threads 0 & 1 SMT4 uses threads 0, 1, 2 & 3 When in any particular SMT mode, all threads have the same performance as each other (ie. at any moment in time, all threads perform the same). The SMT mode switching works such that when linux has threads 2 & 3 idle and 0 & 1 active, it will cede (H_CEDE hypercall) threads 2 and 3 in the idle loop and the hypervisor will automatically switch to SMT2 for that core (independent of other cores). The opposite is not true, so if threads 0 & 1 are idle and 2 & 3 are active, we will stay in SMT4 mode. Similarly if thread 0 is active and threads 1, 2 & 3 are idle, we'll go into SMT1 mode. If we can get the core into a lower SMT mode (SMT1 is best), the threads will perform better (since they share less core resources). Hence when we have idle threads, we want them to be the higher ones. This adds a feature bit for asymmetric packing to powerpc and then enables it on POWER7.

| * powerpc/macio: Fix probing of macio devices by using the right of match tableBenjamin Herrenschmidt2010-06-021-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Grant patches added an of mach table to struct device_driver. However, while he changed the macio device code to use that, he left the match table pointer in struct macio_driver and didn't update drivers to use the "new" one, thus breaking the probing. This completes the change by moving all drivers to setup the "new" one, removing all traces of the old one, and while at it (since it changes the exact same locations), I also remove two other duplicates from struct driver which are the name and owner fields.

| | | | | | | | | | | | | | | | | | | | | | | | | | emulate_step() in kprobe_handler() would've already determined if the probed instruction can be emulated. We single-step in hardware only if the instruction couldn't be emulated. resume_execution() therefore is superfluous -- all we need is to fix up the instruction pointer after single-stepping.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support kexec on FSL-BookE where the MMU can not be simply switched off. The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available.

| | * powerpc/fsl-booke: fix the case where we are not in the first pageSebastian Andrzej Siewior2010-05-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During boot we change the mapping a few times until we have a "defined" mapping. During this procedure a small 4KiB mapping is created and after that one a 64MiB. Currently the offset of the 4KiB page in that we run is zero because the complete startup up code is in first page which starts at RPN zero. If the code is recycled and moved to another location then its execution will fail because the start address in 64 MiB mapping is computed wrongly. It does not consider the offset to the page from the begin of the memory. This patch fixes this. Usually (system boot) r25 is zero so this does not change anything unless the code is recycled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I believe support was disabled due to issues with earlier versions of the board/processor.

The code should be relatively easy to modify to support 44x BookEs as well, but since I don't have any 44x to test, let's confine the code to FSL BookE.

The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Fixed shift of the given offset, to open the maintenance window 2. Mask offset to limit access to the opened maintenance window 3. Added extended destid part to rowtear register, required for 16bit mode This method is matching maintenance transactions generation described by Freescale in the appnote AN2932. With this modification full access to a 16MB maintenance window is possible, this patch is required for IDT cps switches. For easier handling of the access routines, the access was limited to aligned memory regions. This should be no problem because all registers are 32bit wide.

As reported by Stephen Rothwell, it causes problems on big-endian machines: > In file included from fs/jfs/jfs_types.h:33, > from fs/jfs/jfs_incore.h:26, > from fs/jfs/file.c:22: > fs/jfs/endian24.h:36:101: warning: "__LITTLE_ENDIAN" is not defined The kernel has never had that crazy "__BYTE_ORDER == __LITTLE_ENDIAN" model. It's not how we do things, and it isn't how we _should_ do things. So don't go there.
