The patch in question affects system mode, therefore hardware emulation
too. Not a big deal, but, to me, it seems as a natural part of this pull
request. It is quite common that pull requests are not limited by
directories - optimally, they should deal with certain set of related
functionalities, not limited by directories. Why would be that patch be
left lonesome? Could you please, Philippe, reconsider exclusion/inclusion
of this patch, if possible?

Thanks, Aleksandar

This pull request only contains hardware emulation patches (files under

R-b by Richard is here:

The two messages are not directly connected on the list, since r-b was in
June, and the patch was in May.

Can this rx patch be included in this pull request: (it was r-b-ed a couple
of weeks ago already):

https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg08581.html

I apologize, I missed that while rebasing on Igor's memdev work.
I disabled my obsd and win32 builds after they started to fail
few months ago and forgot to re-enable them after they were fixed.

We recently dropped the Travis-CI OSX builds (commit 22a231950)
in favor of Cirrus-CI. There the build succeeded (Mojave):
https://cirrus-ci.com/build/6678899172048896
What is different in your OSX setup?

Also there appears to be a makefile/dependency bug somewhere,
because when I drop this merge attempt and retry building
with current master I get this error:

'aarch64-softmmu/config-devices.mak'.  Stop.
make: *** Waiting for unfinished jobs
make: Leaving directory '/home/petmay01/qemu-for-merges/build/w64'

This seems to be because aarch64-softmmu/config-devices.mak.d
in the build tree says that aarch64-softmmu/config-devices.mak
depends on all the Kconfig files; this means that if a Kconfig
file gets deleted then incremental build stops working?

Hi; I'm afraid there's a format-string issue here (manifests
on OSX, openbsd, and 32-bit platforms):

/home/peter.maydell/qemu/hw/rx/rx-gdbsim.c: In function 'rx_gdbsim_init':
/home/peter.maydell/qemu/hw/rx/rx-gdbsim.c:93:22: error: format '%lli'
expects argument of type 'long long int', but argument 2 has type
'ram_addr_t {aka unsigned int}' [-Werror=format=]
 error_report("Invalid RAM size, should be more than %" PRIi64 " Bytes",
  ^
  mc->default_ram_size);
  

thanks
