looking into kernel source, it seemed quite simple:
./sound/pci/emu10k1/memory.c:
#define get_aligned_page(offset)((offset) >> PAGE_SHIFT)
blk->first_page = get_aligned_page(blk->mem.offset);
blk->last_page = get_aligned_page(blk->mem.offset + blk->mem.size - 1);
psize = get_aligne
Hello,
I have a git clone of the linux kernel tree, and from time to time I
perform git pull. Sometimes new configuration items are added; So after
running "git pull" and "Make", I am asked to answer for questions with
[Y,n] or [N/y/?] (NEW)

Hi,
I have a simple question wrt git. After making few commits in my local
git branch, let's say that I need to rework a patch and resend it
again. In this is it possible to make only the necessary changes in
the required commit and create a patch out of the previous and the new
commit and resend
i think slab can do that,look at
mm/slab.c:
"struct kmem_cache *
kmem_cache_create (const char *name, size_t size, size_t align,
unsigned long flags,
void (*ctor)(struct kmem_cache *, void *))"
the parameter "align" for what?
And kmalloc is page aligned, "4096/16 = 256", is it also 16 aligned?

Oh,sorry vmalloc is page aligned kmalloc is not.

Uhm, kmalloc use slab so I don't think it will be aligned. My wild
guess is you have use alloc_page(s) or use _aligned_

Hi, Can any one please tell me how to back trace the stack ( Program ) when
an exception occurred.
While back tracing how do i get the caller function address? I want to get
all the caller function addresses.This information will be useful to trace
back where exception has occurred.

Hello,
I'm testing real time patch -rt12 on kernel 2.6.21.4.
When I run netperf (netperf -H 192.168.188.207 -t UDP_STREAM -D 1
-I95,5 -l 500 -- -m 1024)
on the server (with rt kernel) I obtain a load of ~48% on IRQ-20
(that is the hard irq related to my ethernet)
but I have no load on softirq-net-
11 matches
