powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

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 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 Signed-off-by: Paul Mackerras

powerpc/pseries: Utilities to set firmware page state

2008-07-25T05:44:42+00:00

Newer versions of firmware support page states, which are used by the collaborative memory manager (future patch) to "loan" pages to the hypervisor for use by other partitions. Signed-off-by: Brian King Signed-off-by: Robert Jennings Acked-by: Paul Mackerras Signed-off-by: Benjamin Herrenschmidt

powerpc/pseries: Add memory entitlement capabilities to /proc/ppc64/lparcfg

2008-07-25T05:44:41+00:00

Update /proc/ppc64/lparcfg to display Cooperative Memory Overcommitment statistics as reported by the H_GET_MPP hcall. This also updates the lparcfg interface to allow setting memory entitlement and weight.

[POWERPC] Avoid hypervisor statistics calculation in real mode

2007-03-22T04:01:43+00:00

kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception. This fixes this problem by using a new plpar_hcall_raw function which does not update the hypervisor call statistics. Thanks to Anton for suggesting this idea.

[POWERPC] Make pSeries use the H_BULK_REMOVE hypervisor call

2007-02-07T03:03:23+00:00

H_BULK_REMOVE lets us remove 4 entries from the MMU hash table with one hypervisor call. This uses it in pSeries_lpar_hpte_invalidate so we can tear down mappings with fewer hypervisor calls. Signed-off-by: Paul Mackerras

[POWERPC] Fix bugs in the hypervisor call stats code

2007-01-09T06:03:03+00:00

There were a few issues with the HCALL_STATS code: - PURR cpu feature checks were backwards - We iterated one entry off the end of the hcall_stats array - Remove dead update_hcall_stats() function prototype I noticed one thing while debugging, and that is we call H_ENTER (to set up the MMU hashtable in early init) before we have done the cpu fixups. This means we will execute the PURR SPR reads even on a CPU that isnt capable of it. I wonder if we can move the CPU feature fixups earlier.

[POWERPC] powerpc: Instrument Hypervisor Calls

2006-09-13T08:39:53+00:00

Add instrumentation for hypervisor calls on pseries. Call statistics include number of calls, wall time and cpu cycles (if available) and are made available via debugfs. Instrumentation code is behind the HCALL_STATS config option and has no impact if not enabled. Signed-off-by: Mike Kravetz Signed-off-by: Paul Mackerras

[POWERPC] clean up pseries hcall interfaces

2006-08-01T06:19:15+00:00

Our pseries hcall interfaces are out of control: plpar_hcall_norets plpar_hcall plpar_hcall_8arg_2ret plpar_hcall_4out plpar_hcall_7arg_7ret plpar_hcall_9arg_9ret Create 3 interfaces to cover all cases: plpar_hcall_norets: 7 arguments no returns plpar_hcall: 6 arguments 4 returns plpar_hcall9: 9 arguments 9 returns There are only 2 cases in the kernel that need plpar_hcall9, hopefully we can keep it that way. Pass in a buffer to stash return parameters so we avoid the &dummy1, &dummy2 madness. Signed-off-by: Anton Blanchard -- Signed-off-by: Paul Mackerras

[POWERPC] Instrument Hypervisor Calls: merge headers
