All guys,
Sorry to bother you.
I have a question to two files, tools/python/xen/lowlevel/xc/xc.c and
tools/python/xen/lowlevel/xl/xl.c. Who is a caller to those methods like
pyxc_methods[] and pyxl_methods[]? And how should we call these approaches?
In my specific case, I'm trying to introduce a new flag to each a device
while assigning device. So this means I have to add a parameter, 'flag',
into
int xc_assign_device(
xc_interface *xch,
uint32_t domid,
uint32_t machine_sbdf)
Then this is extended as
int xc_assign_device(
xc_interface *xch,
uint32_t domid,
uint32_t machine_sbdf,
uint32_t flag)
After this introduction, obviously I should cover all cases using
xc_assign_device(). And also I found this fallout goes into these two
files. For example, here pyxc_assign_device() is involved. Currently it
has two parameters, 'dom' and 'pci_str', and as I understand 'pci_str'
should represent all pci devices with SBDF format, right?
But I don't know exactly what rule should be complied to construct this
sort of flag into 'pci_str', or any reasonable idea to achieve my goal?
Thanks
Tiejun
