 Shouldn't there be an update to roms/openbios to go with the
 pc-bios/openbios-sparc64 binary blob update?

 I haven't committed the sun4u MMIO patches to OpenBIOS yet because
 without the corresponding QEMU parts OpenBIOS SVN trunk breaks (and the
 QEMU parts have taken many weeks to get right which is a long time to
 leave things broken). Hence I've gone for just updating the binary which
 is SVN trunk plus the NVRAM MMIO accessor changes in order to preserve
 bisection.

 As soon as this is applied, I can apply my remaining OpenBIOS patches
 and then send a separate qemu-openbios pull request which will bring
 everything up to date.

 Hmm. I'm not a huge fan of having the binary in git and the submodule
 reference be out of step...

 Alternatively if you have shell access to git.qemu.org then I can commit
 just the MMIO accessor changes to SVN trunk now and then with a manual
 update to the OpenBIOS git mirror I can re-send the signed pull request
 with updated binaries? I've deliberately held off applying patches to
 OpenBIOS SVN trunk in case this was the preferred method as I'm keen to
 be able to bisect down to this particular change on SPARC64.

 Is there any way to make the change backwards compatible, so that we
 don't need to sync versions?

 Not without refactoring to enable more than one type of NVRAM accessor
 in OpenBIOS, plus a fw_cfg variable to enable the switch between the two
 for SPARC64.

 Given that SPARC64 is still more experimental than stable plus newer
 versions of OpenBIOS aren't guaranteed to work with older versions of
 QEMU anyhow, I just can't see that this is worth all the extra effort
 for the sake of a follow-up pull request within a day or so that will
 bring everything up to date whilst still allowing a proper bisection.

 Now if Peter is still keen to keep the git submodule reference intact
 then I'm happy to commit just the MMIO accessor changes to OpenBIOS SVN
 trunk as long as we can minimise the time between the QEMU changes and
 the OpenBIOS changes.
 
 Yes, I think that's a reasonable way forward. Maybe add a fw_cfg and assert() 
 on it nevertheless, so people don't fall into pits ;).

If you're trying to run an old SPARC32/64 OpenBIOS on a newer QEMU then
there are already several pits you could have fallen into ;)  And given
that no-one has reported any issues with this to date then I don't think
it will be a problem.

As it looks like this will happen shortly, I'll go commit the MMIO
changes for SPARC64 to OpenBIOS SVN trunk now. Then as soon as the git
mirror syncs I'll send an updated PULLv2 for Peter.


ATB,

Mark.

 Shouldn't there be an update to roms/openbios to go with the
 pc-bios/openbios-sparc64 binary blob update?

 I haven't committed the sun4u MMIO patches to OpenBIOS yet because
 without the corresponding QEMU parts OpenBIOS SVN trunk breaks (and the
 QEMU parts have taken many weeks to get right which is a long time to
 leave things broken). Hence I've gone for just updating the binary which
 is SVN trunk plus the NVRAM MMIO accessor changes in order to preserve
 bisection.

 As soon as this is applied, I can apply my remaining OpenBIOS patches
 and then send a separate qemu-openbios pull request which will bring
 everything up to date.

 Hmm. I'm not a huge fan of having the binary in git and the submodule
 reference be out of step...
 
 Alternatively if you have shell access to git.qemu.org then I can commit
 just the MMIO accessor changes to SVN trunk now and then with a manual
 update to the OpenBIOS git mirror I can re-send the signed pull request
 with updated binaries? I've deliberately held off applying patches to
 OpenBIOS SVN trunk in case this was the preferred method as I'm keen to
 be able to bisect down to this particular change on SPARC64.

Is there any way to make the change backwards compatible, so that we
don't need to sync versions?

 Not without refactoring to enable more than one type of NVRAM accessor
 in OpenBIOS, plus a fw_cfg variable to enable the switch between the two
 for SPARC64.
 
 Given that SPARC64 is still more experimental than stable plus newer
 versions of OpenBIOS aren't guaranteed to work with older versions of
 QEMU anyhow, I just can't see that this is worth all the extra effort
 for the sake of a follow-up pull request within a day or so that will
 bring everything up to date whilst still allowing a proper bisection.
 
 Now if Peter is still keen to keep the git submodule reference intact
 then I'm happy to commit just the MMIO accessor changes to OpenBIOS SVN
 trunk as long as we can minimise the time between the QEMU changes and
