Peter Maydell e02bbe1956 ppc patch queue 2017-06-06
Accumulated patches for ppc targets and the pseries machine type.
 
 The big thing in this batch is a start on a substantial cleanup of the
 pseries hotplug mechanisms, which were pretty confusing.  For now
 these shouldn't cause substantial behavioural changes, but I am hoping
 these lead to clearer code and eventually to fixes for the bugs we
 have in hotplug handling, particularly when hotplug and migration are
 combined.
 
 The remaining patches are mostly bugfixes.

This function was used in generating the device tree.  However, now that
we have different QOM types for different DRC types we can easily store
the information we need in the class structure and avoid this specialized

David Gibson b8fdd530be spapr: Move configure-connector state into DRC
Currently the sPAPRMachineState contains a list of sPAPRConfigureConnector
structures which store intermediate state for the ibm,configure-connector
RTAS call.

This was an attempt to separate this state from the core of the DRC state.
However the configure connector process is intimately tied to the DRC
model, so there's really no point trying to have two levels of interface
here.

Moving the configure-connector state into its corresponding DRC allows
removal of a number of helpers for maintaining the anciliary list.

David Gibson 2d33581899 spapr: Introduce DRC subclasses
Currently we only have a single QOM type for all DRCs, but lots of
places where we switch behaviour based on the DRC's PAPR defined type.
This is a poor use of our existing type system.

So, instead create QOM subclasses for each PAPR defined DRC type.  We
also introduce intermediate subclasses for physical and logical DRCs,
a division which will be useful later on.

Instead of being stored in the DRC object itself, the PAPR type is now
stored in the class structure.  There are still many places where we
switch directly on the PAPR type value, but this at least provides the
basis to start to remove those.

David Gibson 75e972dab5 migration: Mark CPU states dirty before incoming migration/loadvm
As a rule, CPU internal state should never be updated when
!cpu->kvm_vcpu_dirty (or the HAX equivalent).  If that is done, then
subsequent calls to cpu_synchronize_state() - usually safe and idempotent -
will clobber state.

However, we routinely do this during a loadvm or incoming migration.
Usually this is called shortly after a reset, which will clear all the cpu
dirty flags with cpu_synchronize_all_post_reset().  Nothing is expected
to set the dirty flags again before the cpu state is loaded from the
incoming stream.

This means that it isn't safe to call cpu_synchronize_state() from a
post_load handler, which is non-obvious and potentially inconvenient.

We could cpu_synchronize_all_state() before the loadvm, but that would be
overkill since a) we expect the state to already be synchronized from the
reset and b) we expect to completely rewrite the state with a call to
cpu_synchronize_all_post_init() at the end of qemu_loadvm_state().

To clear this up, this patch introduces cpu_synchronize_pre_loadvm() and
associated helpers, which simply marks the cpu state as dirty without
actually changing anything.  i.e. it says we want to discard any existing
KVM (or HAX) state and replace it with what we're going to load.

Eduardo Habkost 1f43571604 pc: Use "min-[x]level" on compat_props
Since the automatic cpuid-level code was introduced in commit
c39c0edf9b ("target-i386: Automatically
set level/xlevel/xlevel2 when needed"), the CPU model tables just define
the default CPUID level code (set using "min-level").  Setting
"[x]level" forces CPUID level to a specific value and disable the
automatic-level logic.

But the PC compat code was not updated and the existing "[x]level"
compat properties broke compatibility for people using features that
triggered the auto-level code.  To keep previous behavior, we should set
"min-[x]level" instead of "[x]level" on compat_props.

This was not a problem for most cases, because old machine-types don't
have full-cpuid-auto-level enabled.  The only common use case it broke
was the CPUID[7] auto-level code, that was already enabled since the
first CPUID[7] feature was introduced (in QEMU 1.4.0).

This causes the regression reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=1454641

Change the PC compat code to use "min-[x]level" instead of "[x]level" on
compat_props, and add new test cases to ensure we don't break this
again.

Emilio G. Cota 6f1653180f tb-hash: improve tb_jmp_cache hash function in user mode
Optimizations to cross-page chaining and indirect branches make
performance more sensitive to the hit rate of tb_jmp_cache.
The constraint of reserving some bits for the page number
lowers the achievable quality of the hashing function.

However, user-mode does not have this requirement. Thus,
with this change we use for user-mode a hashing function that
is both faster and of better quality than the previous one.

Measurements:

Note: baseline (i.e. speedup == 1x) is QEMU v2.9.0.

Here I also tried the hash function suggested by Paolo ("multhash"):

  return ((uint64_t) (pc * 2654435761) >> 32) & (TB_JMP_CACHE_SIZE - 1);

As you can see it is just as good as the other new function ("hash"),
which is what I ended up going with.

Emilio G. Cota cedbcb0152 tcg: Introduce goto_ptr opcode and tcg_gen_lookup_and_goto_ptr
Instead of exporting goto_ptr directly to TCG frontends, export
tcg_gen_lookup_and_goto_ptr(), which calls goto_ptr with the pointer
returned by the lookup_tb_ptr() helper. This is the only use case
we have for goto_ptr and lookup_tb_ptr, so having this function is
very convenient. Furthermore, it trivially allows us to avoid calling
the lookup helper if goto_ptr is not implemented by the backend.

Richard Henderson 374aae6534 qemu/atomic: Loosen restrictions for 64-bit ILP32 hosts
We need to coordinate with the TCG_OVERSIZED_GUEST test in cputlb.c,
and allow 64-bit atomics even though sizeof(void *) == 4.

Marc-André Lureau 1ce2610c10 char: make chr_fe_deinit() optionaly delete backend
This simplifies removing a backend for a frontend user (no need to
retrieve the associated driver and separate delete call etc).

NB: many frontends have questionable handling of ending a chardev. They
should probably delete the backend to prevent broken reusage.

Marc-André Lureau 4d43a603c7 char: move CharBackend handling in char-fe unit
Move all the frontend struct and methods to a seperate unit. This avoids
accidentally mixing backend and frontend calls, and helps with readabilty.

Make qemu_chr_replay() a macro shared by both char and char-fe.

Export qemu_chr_write(), and use a macro for qemu_chr_write_all()

(nb: yes, CharBackend is for char frontend :)

Assorted accumulated patches.  These are nearly all bugfixes at one

 This includes preliminary patches towards fixing migration for Radix
 Page Table guests under POWER9 and also fixing some migration
 regressions due to the re-organization of the interrupt controller
 code.  Not all the pieces are there yet, so those still won't quite
 work, but the preliminary changes make sense on their own.

Max Reitz 03c320d803 block/file-*: *_parse_filename() and colons
The file drivers' *_parse_filename() implementations just strip the
optional protocol prefix off the filename. However, for e.g.
"file:foo:bar", this would lead to "foo:bar" being stored as the BDS's
filename which looks like it should be managed using the "foo" protocol.
This is especially troublesome if you then try to resolve a backing
filename based on "foo:bar".

This issue can only occur if the stripped part is a relative filename
("file:/foo:bar" will be shortened to "/foo:bar" and having a slash
before the first colon means that "/foo" is not recognized as a protocol
part). Therefore, we can easily fix it by prepending "./" to such
filenames.

Before this patch:
$ ./qemu-img create -f qcow2 backing.qcow2 64M
Formatting 'backing.qcow2', fmt=qcow2 size=67108864 encryption=off
    cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ ./qemu-img create -f qcow2 -b backing.qcow2 file🔝image.qcow2
Formatting 'file🔝image.qcow2', fmt=qcow2 size=67108864
    backing_file=backing.qcow2 encryption=off cluster_size=65536
    lazy_refcounts=off refcount_bits=16
$ ./qemu-io file🔝image.qcow2
can't open device file🔝image.qcow2: Could not open backing file:
    Unknown protocol 'top'

After this patch:
$ ./qemu-io file🔝image.qcow2
[no error]
