* powerpc/pseries: Add extended_cede_processor() helper function.Gautham R Shenoy2009-11-241-1/+8
| | | | | | | | | | | This patch provides an extended_cede_processor() helper function which takes the cede latency hint as an argument. This hint is to be passed on to the hypervisor to cede to the corresponding state on platforms which support it.

* powerpc: Shield code specific to 64-bit server processorsBenjamin Herrenschmidt2009-06-091-0/+6
| | | | | | | | | | | This is a random collection of added ifdef's around portions of code that only mak sense on server processors. Using either CONFIG_PPC_STD_MMU_64 or CONFIG_PPC_BOOK3S as seems appropriate. This is meant to make the future merging of Book3E 64-bit support easier.

* powerpc/pseries: Add dispatch dispersion statisticsAnton Blanchard2009-04-071-1/+1
| | | | | | | | PHYP tells us how often a shared processor dispatch changed physical cpus. This can highlight performance problems caused by the hypervisor. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Add dispatch trace log fields to lppacaJeremy Kerr2009-03-241-2/+4
| | | | | | | | | PAPR v2.3 defines fields in the virtual processor area for a dispatch trace log (DLT). Since we'd like to use the DLT, add the necessary fields to struct lppaca. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc: Fix page_ins details in lppaca commentsJeremy Kerr2009-03-241-1/+1
| | | | | | | | The page_ins member ends at byte 0x3, not 0x4. Also, fix up the alignment. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc: Update page-in counter for CMMBrian King2008-11-051-1/+2
| | | | | | | | | | | A new field has been added to the VPA as a method for the client OS to communicate to firmware the number of page-ins it is performing when running collaborative memory overcommit. The hypervisor will use this information to better determine if a partition is experiencing memory pressure and needs more memory allocated to it.

* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-041-0/+159
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
