[PATCH] unify pfn_to_page: generic functions · a117e66e

KAMEZAWA Hiroyuki authored Mar 27, 2006

There are 3 memory models, FLATMEM, DISCONTIGMEM, SPARSEMEM.
Each arch has its own page_to_pfn(), pfn_to_page() for each models.
But most of them can use the same arithmetic.

This patch adds asm-generic/memory_model.h, which includes generic
page_to_pfn(), pfn_to_page() definitions for each memory model.

When CONFIG_OUT_OF_LINE_PFN_TO_PAGE=y, out-of-line functions are
used instead of macro. This is enabled by some archs and  reduces
text size.

[PATCH] sched: new sched domain for representing multi-core · 1e9f28fa

Siddha, Suresh B authored Mar 27, 2006

Add a new sched domain for representing multi-core with shared caches
between cores.  Consider a dual package system, each package containing two
cores and with last level cache shared between cores with in a package.  If
there are two runnable processes, with this appended patch those two
processes will be scheduled on different packages.

On such systems, with this patch we have observed 8% perf improvement with
specJBB(2 warehouse) benchmark and 35% improvement with CFP2000 rate(with 2
users).

This new domain will come into play only on multi-core systems with shared
caches.  On other systems, this sched domain will be removed by domain
degeneration code.  This new domain can be also used for implementing power
savings policy (see OLS 2005 CMP kernel scheduler paper for more details..
I will post another patch for power savings policy soon)

Most of the arch/* file changes are for cpu_coregroup_map() implementation.

[PATCH] sched: fix task interactivity calculation · 013d3868

Martin Andersson authored Mar 27, 2006

Is a truncation error in kernel/sched.c triggered when the nice value is
negative.  The affected code is used in the TASK_INTERACTIVE macro.

The code is:
#define SCALE(v1,v1_max,v2_max) \
	(v1) * (v2_max) / (v1_max)

which is used in this way:
SCALE(TASK_NICE(p), 40, MAX_BONUS)

Comments in the code says:
  * This part scales the interactivity limit depending on niceness.
  *
  * We scale it linearly, offset by the INTERACTIVE_DELTA delta.
  * Here are a few examples of different nice levels:
  *
  *  TASK_INTERACTIVE(-20): [1,1,1,1,1,1,1,1,1,0,0]
  *  TASK_INTERACTIVE(-10): [1,1,1,1,1,1,1,0,0,0,0]
  *  TASK_INTERACTIVE(  0): [1,1,1,1,0,0,0,0,0,0,0]
  *  TASK_INTERACTIVE( 10): [1,1,0,0,0,0,0,0,0,0,0]
  *  TASK_INTERACTIVE( 19): [0,0,0,0,0,0,0,0,0,0,0]
  *
  * (the X axis represents the possible -5 ... 0 ... +5 dynamic
  *  priority range a task can explore, a value of '1' means the
  *  task is rated interactive.)

However, the current code does not scale it linearly and the result differs
from the given examples.  If the mathematical function "floor" is used when
the nice value is negative instead of the truncation one gets when using
integer division, the result conforms to the documentation.

Output of TASK_INTERACTIVE when using the kernel code:

[PATCH] knfsd: Unexport cache_fresh and fix a small race · ebd0cb1a

NeilBrown authored Mar 27, 2006

Cache_fresh is now only used in cache.c, so unexport it.

Part of cache_fresh (setting CACHE_VALID) should really be done under the
lock, while part (calling cache_revisit_request etc) must be done outside the
lock.  So we split it up appropriately.

[PATCH] knfsd: An assortment of little fixes to the sunrpc cache code · 4013edea

NeilBrown authored Mar 27, 2006

- in cache_check, h must be non-NULL as it has been de-referenced,
  so don't bother checking for NULL.

- When a cache-item is updated, we need to call cache_revisit_request to see
  if there is a pending request waiting for that item.  We were using
  a transition to CACHE_VALID to see if that was needed, however that is
  wrong as an expired entry will still be marked 'valid' (as the data is valid
  and will need to be released).  So instead use an off transition for
  CACHE_PENDING which is exactly the right thing to test.

- Add a little bit more debugging info.
