This behaves in the same way as Linux. The 64 byte limit is arbitrary but long enough for practical purposes. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Release-acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Re-structured code. Signed-off-by: Jan Beulich <jbeulich@suse.com>

Xen custom %p format options. A subset, borrowed from Linux.
|
|
|
|
All parameters to a %p option should be compatible with void*. Regular
|
|
pointers are fine. Numbers should make use of the _p() macro.
|
|
|
|
Raw buffer as hex string:
|
|
|
|
%*ph Up to 64 characters, printed as "00 01 02 ... ff". Buffer length
|
|
expected via the field_width paramter. i.e. printk("%*ph", 8, buffer);
|
|
|
|
Symbol/Function pointers:
|
|
|
|
%ps Symbol name with condition offset and size (iff offset != 0)
|
|
e.g. printk
|
|
default_idle+0x78/0x7d
|
|
|
|
%pS Symbol name with unconditional offset and size
|
|
e.g. printk+0/0x48
|
|
default_idle+0x78/0x7d
|
|
|
|
In the case that an appropriate symbol name can't be found, %p[sS] will
|
|
fall back to '%p' and print the address in hex.
|
|
|
|
Domain and vCPU information:
|
|
|
|
%pv Domain and vCPU ID from a 'struct vcpu *' (printed as
|
|
"d<domid>v<vcpuid>")
|
