[patch 00/10] Per cpu code simplification V2

[patch 00/10] Per cpu code simplification V2

[Christoph Lameter]

This patchset simplifies the code that arches need to maintain to support
per cpu functionality. Most of the code is moved into arch independent
code. Only a minimal set of definitions is kept for each arch.

The patch also unifies the x86 arch so that there is only a single
asm-x86/percpu.h

V1->V2:
- Add support for specifying attributes for per cpu declarations (preserves
  IA64 model(small) attribute).
- Drop first patch that removes the model(small) attribute for IA64
- Missing #endif in powerpc generic config /  Wrong Kconfig
- Follow Randy's suggestions on how to do the Kconfig settings
- Rediff against 2.6.24-rc3-mm2

[patch 01/10] percpu: Use a kconfig variable to signal arch specific percpu setup

[Christoph Lameter]

[-- Attachment #1: arch_sets_up_per_cpu_areas --]
[-- Type: text/plain, Size: 4838 bytes --]

V1->V2:
- Use def_bool as suggested by Randy.

The use of the __GENERIC_PERCPU is a bit problematic since arches
may want to run their own percpu setup while using the generic
percpu definitions. Replace it through a kconfig variable.

[patch 02/10] percpu: Move arch XX_PER_CPU_XX definitions into linux/percpu.h

[Christoph Lameter]

[-- Attachment #1: move_percpu_declarations --]
[-- Type: text/plain, Size: 13668 bytes --]

V1->V2:
- Special consideration for IA64: Add the ability to specify
  arch specific per cpu flags

The arch definitions are all the same. So move them into linux/percpu.h.

We cannot move DECLARE_PER_CPU since some include files just include
asm/percpu.h to avoid include recursion problems.

[patch 03/10] percpu: Make the asm-generic/percpu.h more "generic"

[Christoph Lameter]

[-- Attachment #1: genericize-percpu.h --]
[-- Type: text/plain, Size: 4180 bytes --]

V1->V2:
- add support for PER_CPU_ATTRIBUTES

Add the ability to use generic/percpu even if the arch needs to override
several aspects of its operations. This will enable the use of generic
percpu.h for all arches.

An arch may define:

__per_cpu_offset	Do not use the generic pointer array. Arch must
			define per_cpu_offset(cpu) (used by x86_64, s390).

__my_cpu_offset		Can be defined to provide an optimized way to determine
			the offset for variables of the currently executing
			processor. Used by ia64, x86_64, x86_32, sparc64, s/390.

SHIFT_PTR(ptr, offset)	If an arch defines it then special handling
			of pointer arithmentic may be implemented. Used
			by s/390.


(Some of these special percpu arch implementations may be later consolidated
so that there are less cases to deal with.)

note that this did not apply cleanly to latest x86.git. Could you

This is a core change against Andrew's tree. It needs to go into mm and 
not into the x86 tree. It is no surprise that this does not apply cleanly 
to the x86 tree.

well since they affect the x86 tree quite heavily (and a dependent 
patchset you sent is basically for x86 only), it looked quite plausible 
to check how they fare.

Yes that can be done by downloading 2.6.24-rc3-mm2 and 
applying the patches on top of it. There are various earlier cleanup 
patches in mm that fix various core issues that make all of this possible.

It would be great if you could review the patches and test them.

which are those patches? I found only a single relevant patch:

 modules-fold-percpu_modcopy-into-modulec-and-get-rid-of-the-macro-from-hell.patch

anything else i missed?

this patch should have no relevance to the crash i reported. (i use a 
bzImage) It's also a cleanup patch only, it should not affect 
correctness.

as expected, with that patch applied, the kernel crashes and reboots 
(with no message this time). If you could point out any other dependent 
patches besides the one above (if any) that would be great.

Ok. Just looking at mm-commits:

Re: [patch 03/10] percpu: Make the asm-generic/percpu.h more "generic"

The .config does not compile under mm. Could you verify that the first 
patchset applies (this one) and works fine before we get to to the 
patchset that deals with relocating the percpu addresses?

Seems that there are some other funky features on:

CONFIG_PHYSICAL_START=0x100000
CONFIG_RELOCATABLE=y
CONFIG_PHYSICAL_ALIGN=0x200000

I gotta see how much of that is available under mm and how it interacts 
with the relocation of the percpu area.

Re: [patch 03/10] percpu: Make the asm-generic/percpu.h more "generic"

[Christoph Lameter]

Ahh this is a UP configuration! For that case we do not rebase the percpu 
area to address 0. And all the reports of success are until now for 
SMP/NUMA. Switching SMP on makes your config boot fine.

I thought I left UP handling unchanged. There must be some subtle 
change. Looking for it now.

Hi Christoph,

Powerpc has a way to determine the address of the per cpu area of the
currently executing processor via the paca and the array of per cpu
offsets is avoided by looking up the per cpu area from the remote
paca's (copying x86_64).

[patch 08/10] Sparc64: Use generic percpu

[Christoph Lameter]

[-- Attachment #1: sparc64_generic_percpu --]
[-- Type: text/plain, Size: 2559 bytes --]

Sparc64 has a way of providing the base address for the per cpu area of the
currently executing processor in a global register.

Sparc64 also provides a way to calculate the address of a per cpu area
from a base address instead of performing an array lookup.

[patch 09/10] ia64: Use generic percpu

[Christoph Lameter]

[-- Attachment #1: ia64_generic_percpu --]
[-- Type: text/plain, Size: 3128 bytes --]

V1->V2:
- Merge fixes
- Remove transitional check for PER_CPU_ATTRIBUTES from linux/percpu.h

ia64 has a special processor specific mapping that can be used to locate the
offset for the current per cpu area.

[PATCH 00/10] percpu: Per cpu code simplification V2

[travis]

This patchset simplifies the code that arches need to maintain to support
per cpu functionality. Most of the code is moved into arch independent
code. Only a minimal set of definitions is kept for each arch.

The patch also unifies the x86 arch so that there is only a single
asm-x86/percpu.h

V1->V2:
- Add support for specifying attributes for per cpu declarations (preserves
  IA64 model(small) attribute).
  - Drop first patch that removes the model(small) attribute for IA64
  - Missing #endif in powerpc generic config /  Wrong Kconfig
  - Follow Randy's suggestions on how to do the Kconfig settings

[PATCH 03/10] percpu: Make the asm-generic/percpu.h more "generic"

[travis]

[-- Attachment #1: genericize-percpu.h --]
[-- Type: text/plain, Size: 3984 bytes --]

V1->V2:
- add support for PER_CPU_ATTRIBUTES

Add the ability to use generic/percpu even if the arch needs to override
several aspects of its operations. This will enable the use of generic
percpu.h for all arches.

An arch may define:

__per_cpu_offset	Do not use the generic pointer array. Arch must
			define per_cpu_offset(cpu) (used by x86_64, s390).

__my_cpu_offset		Can be defined to provide an optimized way to determine
			the offset for variables of the currently executing
			processor. Used by ia64, x86_64, x86_32, sparc64, s/390.

SHIFT_PTR(ptr, offset)	If an arch defines it then special handling
			of pointer arithmentic may be implemented. Used
			by s/390.


(Some of these special percpu arch implementations may be later consolidated
so that there are less cases to deal with.)

			processor. Used by ia64, x86_64, x86_32, sparc64, s/390.

SHIFT_PTR(ptr, offset)	If an arch defines it then special handling
			of pointer arithmentic may be implemented. Used
			by s/390.


(Some of these special percpu arch implementations may be later consolidated
so that there are less cases to deal with.)

[PATCH 00/10] percpu: Per cpu code simplification V4

[travis]

This patchset simplifies the code that arches need to maintain to support
per cpu functionality. Most of the code is moved into arch independent
code. Only a minimal set of definitions is kept for each arch.

The patch also unifies the x86 arch so that there is only a single
asm-x86/percpu.h

Based on: 2.6.24-rc6-mm1
---

V1->V2:
- Add support for specifying attributes for per cpu declarations (preserves
  IA64 model(small) attribute).
  - Drop first patch that removes the model(small) attribute for IA64
  - Missing #endif in powerpc generic config /  Wrong Kconfig
  - Follow Randy's suggestions on how to do the Kconfig settings

V2->V3:
  - fix x86_64 non-SMP case
  - change SHIFT_PTR to SHIFT_PERCPU_PTR
  - fix various percpu_modcopy()'s to reference correct per_cpu_offset()
  - s390 has a special way to determine the pointer to a per cpu area

V3->V4:
  - rebased patchset on 2.6.24-rc6-mm1
    (removes the percpu_modcopy changes that are already in.)
  - change config ARCH_SETS_UP_PER_CPU_AREA to a global var
    and use select HAVE_SETUP_PER_CPU_AREA to specify.

[PATCH 03/10] percpu: Make the asm-generic/percpu.h more "generic"

[travis]

[-- Attachment #1: genericize-percpu.h --]
[-- Type: text/plain, Size: 4171 bytes --]

Add the ability to use generic/percpu even if the arch needs to override
several aspects of its operations. This will enable the use of generic
percpu.h for all arches.

An arch may define:

__per_cpu_offset	Do not use the generic pointer array. Arch must
			define per_cpu_offset(cpu) (used by x86_64, s390).

__my_cpu_offset		Can be defined to provide an optimized way to determine
			the offset for variables of the currently executing
			processor. Used by ia64, x86_64, x86_32, sparc64, s/390.

SHIFT_PERCPU_PTR(ptr, offset)	If an arch defines it then special handling
			of pointer arithmentic may be implemented. Used
			by s/390.


(Some of these special percpu arch implementations may be later consolidated
so that there are less cases to deal with.)

V1->V2:
- add support for PER_CPU_ATTRIBUTES

V2->V3:
- fix generic smp percpu_modcopy to use per_cpu_offset() macro.

V3->V4:
- change to use CONFIG_HAVE_SETUP_PER_CPU_AREA
