Hi, Stefano!
Error numbers
The numbers corresponding to the error names specified by POSIX are:
[EPERM] -1
[ENOENT]-2
Don't you want to use Xen's errno.h here as described in [1]?
So we have error codes consistent for all PV protocols?

kernel has XEN_PAGE_S
Hi, all!
While working on display protocol I found that there is no(?) common
???_PAGE_SIZE define I can use for both Xen and Linux kernel:
Xen defines XC_PAGE_SIZE which is also used in Linux user-space and
kernel has XEN_PAGE_SIZE, but no XC_PAGE_SIZE.
So, the question is which define shoul
Thank you for explanation, now it is clear.
BTW, is PAGE_SHARED the right choice in my case
or should I use something else instead?
Thank you,
Oleksandr

Hi,
I cannot find any definition of XC_PAGE_SIZE for Linux kernel.
Is it by intention or just missed?
I am writing a PV front drivers now and forced either to define
XC_PAGE_SIZE
Hi, all!
I cannot find any definition of XC_PAGE_SIZE for Linux kernel.
Is it by intention or just missed?
I am writing a PV front drivers now and forced either to define
XC_PAGE_SIZE == PAGE_SIZE or use PAGE_SIZE directly. Strictly
speaking both workarounds are not correct.
Thank you,
