QEMU exit (which can be guest triggered) can be replaced by:

However, for current ones (1.2 or later), I don't want to have them
by default as it is an QEMU exit which is guest triggerable.
Will you accept this approach, where your regression suite will require
a new parameter "-device isa-debugexit,iobase=0x501" ?
Yes although I'd prefer the iobase not be required to be explicitly
specified.
Which one are you using? iobase 0x501 or 0x502? And with access size 1
or 2?

This discussion seems to have died out without result... Hervé, do you
have a newer patchset with either of the two default addresses?

Andreas


I may only need to change the default iobase and access-size values in first patch. They are currently at 0x501 with an access size of 1, but I got no answer from Anthony if those are the values he wants.
