Why must linux driver be modified?

Hi,
after the comments, here is my updated patch for ptc.ga
Please comment it.
With this patch, the page_flags are always written atomically. Ptc only clear
it. This eliminates itc and ptc conflicts.
The other conflict is use. This is within ia64_page_fault, between

Hi xen/ia64 developers.
The attached patch supports discontiguous memory.
It also makes over 4GB memory available.
Please comment and review.

Good work, Kouya.
I have no idea which has good performance.

When the arch/ia64/Makefile was cloned from the Linux tree, the install

It's OK to start from easy way first, and then evaluate which one is better.
From what I recalled, there's no obvious preference on ia64/linux
community upon these two approaches(simplicity Vs complex, TLB Vs
cache) and that's why two approaches still
Hi everybody.
I let the Red Hat installer decide how to partition my disks and it used
logical volumes so I found that I needed support for them in my kernel.
This is just a tiny patch that turns on those configuration options.

A page(swapper_pg_dir) pointed from init_mm.pgd seems to be never

Thanks for your comments.

If you can measure the TLB miss ratio of accessing vmemmap, that could

My guess is that the TLB miss ratio is quite worse because
vmemmap(frame_table) is usually accessed only by grant table operation
Hi Alex,
[TODO]
* mpt_table (defined in xen/arch/ia64/xen/xenmem.c) implies the same
problem. We have to fix it.
Maybe you hit the abobe issue.
0-260GB address space requres contiguous 130MB area for mpt_table.
mpt_table is still allocated from xen heap(up to 64MB) and
the area
