Hi,
I have a hypercall implemented and I need to access the memory pages
allocated for the process calling this hypercall within the hypercall handler.
If i could get any pointers on this it would be great.
Thank you very much.
Regards,
Satyajeet

Hi,
Can anyone please tell me how should acquire the memory pages for a process.
I want to achieve this from the hypercall handler so from within Xen. Also the
process whose memory pages I wish to acquire is the same process that is
initiating the hypercall.
Thank you.
Regards,
Satyajeet

Have you tried looking for an existing hypercall which does something similar to what you want, to get a hint how it might be done? -George On Thu, Nov 11, 2010 at 9:49 PM, Nimgaonkar, Satyajeet <SatyajeetNimgaonkar@my.unt.edu> wrote:> Hi, > Can anyone please tell me how should acquire the memory pages for a > process.

Hi George,
Thank you for your response. I have already implemented a custom
hypercall and I want to access the memory pages allocated for a particular
process, with in this hypercall handler. So I was not quite sure if I can
initiate a hypercall from my custom hypercall handler i.e. from with in xen.
I would appreciate if you could help further in this.
Thanks.
Regards,
Satyajeet

I meant, you can see how that hypercall does it and copy its technique. -G On Fri, Nov 12, 2010 at 5:31 PM, Nimgaonkar, Satyajeet <SatyajeetNimgaonkar@my.unt.edu> wrote:> Hi George, > Thank you for your response.
