[Qemu-devel] Tracing memory accesses by emulated systems

[Qemu-devel] Tracing memory accesses by emulated systems

[Christian Leber]

Hello,

I would like to trace all "physical" memory read/write operations for x86_64,
but I have to admit that I'm not sure where exactly this has to be
implemented.

Could somebody give me some hints where and how I could do that?
(or is there already a patch that does this? on irc somebody suggested
that something like that could exist, but I was not able to find it)

Regards

Christian Leber

hello christian!

i'm not sure if it applies for 64bit (but i'd assume it does).
afaik the easiest way to catch "all" (dma operations are not covered
there - i think) memory accesses is via the ld*,st* macros in
softmmu_helper.h and softmmu_header.h. at least this is the way i did
that.
