The printk formats %*ph{C,D,N} are chosen to be compatible with their Linux
counterparts.
Sample:
(XEN) buf: 00 01 03 07 78 65 6e 00
(XEN) buf: 00:01:03:07:78:65:6e:00
(XEN) buf: 00-01-03-07-78-65-6e-00
(XEN) buf: 0001030778656e00

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 00 01 02 ... 3f
|
|
%*phC 00:01:02: ... :3f
|
|
%*phD 00-01-02- ... -3f
|
|
%*phN 000102 ... 3f
|
|
|
|
Up to 64 characters. 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>")
|
