This adds a trace point which prints every loaded image. This includes
bios/firmware/kernel/initradmdisk/pcirom.

The example for a pseries guest:
loader_write_rom slof.bin: @0x0 size=0xe22e0 ROM=0
loader_write_rom phdr #0: /home/aik/t/vml4120le: @0x400000 size=0x13df000 ROM=0
loader_write_rom /home/aik/t/le.cpio: @0x1ad0000 size=0x9463a00 ROM=0
Sadly "spapr-rtas.bin" does not show up because it is loaded from
the spapr machine reset handler rather than via rom_reset(), may be needs
to be fixed.

Hi,
This series failed the asan build test. Please find the testing commands and

I find the "ROM=0" part confuse, maybe you can change to "ROM:false".

How? I mean I can do that in the code as rom->isrom?"true":"false" and
make trace point accept "%s" but it is quite ugly and others seem to
just use %d for bool.

Yes, %d is the convention for bool. Perhaps you can name it "is_rom"
instead of "ROM". That way the name communicates that this is a boolean

I agree a boolean is easier to parse for trace analyzer tools than a
"true/false" string.
Stefan, is it possible to add a boolean format string to the backends?
For example the 'log' backend would log it as "true"/"false".
Just a thought ;)
Regards,
Phil.

It is quite obvious though that it is boolean even as "ROM" (what else
can that be realistically?) and there does not seem to be a convention
about xxx:N vs is_xxx:N. And personally I find longer lines worse for
limited width screens (I run multiple qemus in tiled tmux). Whose tree
is this going to? Let's ask that person :)

Personally I find 'is_rom' clearer. I read 2 addresses, then my first
reaction was to parse it as another address. But it is also true we now
enforce traced hex values with '0x' prefix, so your 'ROM' is unlikely an
address. Tiled tmux is an acceptable argument. Anyway you already got my
R-b.
Tree: the PPC tree is likely to get it merged quicker than the MISC tree.

Phil.

There is nothing specific about PPC though so I guess it is the MISC
tree, who does maintain that?

Yes. The format string in trace-events is not used by all trace
backends, and they are free to do whatever they like (e.g. by looking at
the C types of the trace event arguments).

Stefan sometime takes tracing patches, but this patch might also go via
