[Qemu-devel] [PULL] Memory API conversions, batch 5

[Qemu-devel] [PULL] Memory API conversions, batch 5

[Avi Kivity]

Please pull from

   git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git memory/batch

to receive the fifth memory API conversions batch.  There is really 
nothing notable, except perhaps the first use of the transaction API.

While the patches have been on the list for just a short time, they have 
received quite extensive review, for which I am thankful.

Avi Kivity (22):
       stellaris_enet: convert to memory API
       sysbus: add helpers to add and delete memory regions to the 
system bus
       pci_host: convert conf index and data ports to memory API
       ReadWriteHandler: remove
       an5206: convert to memory API
       armv7m: convert to memory API
       axis_dev88: convert to memory API (RAM only)
       sysbus: add sysbus_add_memory_overlap()
       integratorcp: convert to memory API (RAM/flash only)
       leon3: convert to memory API
       cirrus: wrap memory update in a transaction
       piix_pci: wrap memory update in a transaction
       Makefile.hw: allow hw/ files to include glib headers
       pflash_cfi01/pflash_cfi02: convert to memory API

I have a truly marvellous patch that fixes the bug which this

Guys, please start testing before applying these patches. It's not hard,
there are images on the wiki with scripts that area easy to run.

Cheers

It's also possible to revert offending patches. But a better solution
would be to have a comprehensive test setup to do builds and run
checks on selected trees. Before a pull to main tree, the test results
should be available.

Before a pull *request*.  Semantically, pull requests should be treated 
as a push.  It's the submaintainers responsibility to test the bits they 
do a pull request for.

That said, the logistics of testing a series like this is mind numbingly 
complex.  We really need to all work on better automation for this.  In 
the interim, I think we're just going to have to leave with occasional 
breakage from changes like this and make sure it doesn't happen too 
frequently.

Then all maintainers should have the same understanding of what to test.

Alex's simple script idea for kernel devs could be reused here. The
following would already catch a few errors:
#!/bin/sh
set -e
mkdir obj
cd obj
../configure
make -j
for f in ./*-softmmu/qemu-system-* ./i386-softmmu/qemu; do
  echo running $f, exit with Ctrl-a x:
  $f
done

This could be integrated to Makefile as well, maybe even generate
timestamp files which would be read by git commit hooks to add extra
lines about test status.

In my opinion, the way to spread that understanding is a working "make
check".  Make it fail constructively when it needs more stuff installed,
like test images, or additional software.

Anything more complicated than such a one-liner is bound to be misused,
forgotten, or ignored.

Heck, if it's that simple, even non-maintainers could use it ;)

Yes, I understand its not an easy to test all combinations. But there
are scripts that testrun various targets on the wiki. It doesnt take
long to run those. You can also explicitely ask for help with the testing.
I'm happy to assist if the test scripts dont run or if you CC me on
a testme request.

Avi's done a great job with these series, converting all targets and all.
I dont mean to misscredit that.

Cheers

Please revert the entire pull (git revert 8ef9ea85a2cc1) while I work 
this out - it isn't trivial.

True, we should be able to get kvm-autotest to do a sanity test.

That looks pretty much like what I stumbled over today as well. Should
be fine with [1], need to test again.

I did and it's not, need to find an opaque from somewhere and initialize 
that too.

Ugh, yeah, the result is different but still broken.
