qcow2: Don't strand clusters near 2G intervals during commit

The qcow2_make_empty() function is reached during 'qemu-img commit',
in order to clear out ALL clusters of an image.  However, if the
image cannot use the fast code path (true if the image is format
0.10, or if the image contains a snapshot), the cluster size is
larger than 512, and the image is larger than 2G in size, then our
choice of sector_step causes problems.  Since it is not cluster
aligned, but qcow2_discard_clusters() silently ignores an unaligned
head or tail, we are leaving clusters allocated.

Enhance the testsuite to expose the flaw, and patch the problem by
ensuring our step size is aligned.

target-arm/translate-a64: fix gen_load_exclusive

While testing rth's latest TCG patches with risu I found ldaxp was
broken. Investigating further I found it was broken by 1dd089d0 when
the cmpxchg atomic work was merged. As part of that change the code
attempted to be clever by doing a single 64 bit load and then shuffle
the data around to set the two 32 bit registers.

As I couldn't quite follow the endian magic I've simply partially
reverted the change to the original code gen_load_exclusive code. This
doesn't affect the cmpxchg functionality as that is all done on in
gen_store_exclusive part which is untouched.

I've also restored the comment that was removed (with a slight tweak
to mention cmpxchg).

which we know always works.

This should cover all remaining testsuite uses of

The use of PRId64 for a variable named 'pid' is gross, but it
is a sad reality of the 64-bit mingw environment, which
mistakenly defines pid_t as a 64-bit type even though getpid()
returns 'int' on that platform [2].  Our definition of the
QGA GuestExec type defines 'pid' as a 64-bit entity, and we
can't tighten it to 'int32' unless the mingw header is fixed.
Using 'long long' instead of 'int64_t' just so that we can
stick with qobject_from_jsonv("%lld") instead of printf() is
not any prettier, since we may have later type churn anyways.

a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG regardless of whether there was a

Where this gets ugly is that when applying the resolution changes,
gnome-shell/mutter will call drmModeRmFB, drmModeAddFB, and
drmModeSetCrtc, which will cause the primary surface to be destroyed and

an interrupt with an unchanged monitors configuration, ...

spapr: fix default DRC state for coldplugged LMBs

Currently we set the initial isolation/allocation state for DRCs
associated with coldplugged LMBs to ISOLATED/UNUSABLE,
respectively, under the assumption that the guest will move this
state to UNISOLATED/USABLE.

In fact, this is only the case for LMBs added via hotplug. For
coldplugged LMBs, the guest actually assumes the initial state to
be UNISOLATED/USABLE.

In practice, this only becomes an issue when we attempt to unplug
one of these LMBs, where the guest kernel will issue an
rtas-get-sensor-state call to check that the corresponding DRC is
in an USABLE state before it will release the LMB back to
QEMU. If the returned state is otherwise, the guest will assume no
further action is needed, which bypasses the QEMU-side cleanup that
occurs during the USABLE->UNUSABLE transition. This results in
LMBs and their corresponding pc-dimm devices to stick around
indefinitely.

This patch fixes the issue by manually setting DRCs associated with
cold-plugged LMBs to UNISOLATED/ALLOCATED, but leaving the hotplug
state untouched. As it turns out, this is analogous to the handling
for cold-plugged CPUs in spapr_core_plug().

7 years agoloader: fix handling of custom address spaces when adding ROM blobs
Laszlo Ersek [Tue, 29 Nov 2016 19:55:32 +0000 (20:55 +0100)]
loader: fix handling of custom address spaces when adding ROM blobs

* Commit 3e76099aacb4 ("loader: Allow a custom AddressSpace when loading
  ROMs") introduced the "Rom.as" field:

  (1) It modified the utility callers of rom_insert() to take "as" as a
      new parameter from *their* callers, and set "rom->as" from that
      parameter. The functions covered were rom_add_file() and
      rom_add_elf_program().

  (2) It also modified rom_insert() itself, to auto-assign
      "&address_space_memory", in case the external caller passed -- and
      the utility caller forwarded -- as=NULL.

  Except, commit 3e76099aacb4 forgot to update the third utility caller of
  rom_insert(), under point (1), namely rom_add_blob().

* Later, commit 5e774eb3bd264 ("loader: Add AddressSpace loading support
  to uImages") added the load_uimage_as() function, and the
  rom_add_blob_fixed_as() function-like macro, with the necessary changes
  elsewhere to propagate the new "as" parameter to rom_add_blob():

    load_uimage_as()
      load_uboot_image()
        rom_add_blob_fixed_as()
          rom_add_blob()

  At this point, the signature (and workings) of rom_add_blob() had been
  broken already, and the rom_add_blob_fixed_as() macro passed its "_as"
  parameter to rom_add_blob() as "callback_opaque". Given that the
  "fw_callback" parameter itself was set to NULL (correctly), this did no
  additional damage (the opaque arg would never be used), but ultimately
  it broke the new functionality of load_uimage_as().

* The load_uimage_as() function would be put to use in one of the later
  patches, commit e481a1f63c93 ("generic-loader: Add a generic loader").

* We can fix this only in a unified patch now. Append "AddressSpace *as"
  to the signature of rom_add_blob(), and handle the new parameter. Pass
  NULL from all current callers, except from rom_add_blob_fixed_as(),
  where "_as" has to be bumped to the proper position.

* Note that rom_add_file() rejects the case when both "mr" and "as" are
  passed in as non-NULL. The action that this is apparently supposed to
  prevent is the

    rom->mr = mr;

  assignment (that's the only place where the "mr" parameter is used in
  rom_add_file()). In rom_add_blob() though, we have no "mr" parameter,
  and the actions done on the fw_cfg branch:

    if (fw_file_name && fw_cfg) {
        if (mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
            mr = rom->mr;
        } else {
            data = rom->data;
        }

  reflect those that are performed by rom_add_file() too (with mr==NULL):

    if (rom->fw_file && fw_cfg) {
        if ((!option_rom || mc->option_rom_has_mr) &&
            mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
        } else {
            data = rom->data;
        }

  Hence we need no additional restrictions in rom_add_blob().

* Stable is not affected as both problematic commits appeared first in
  v2.8.0-rc0.

hbitmap: Fix shifts of constants by granularity

An hbitmap's granularity may be anything from 0 to 63, so when shifting
constants by its value, they should not be plain ints.

Even having changed the types, hbitmap_serialization_granularity() still
tries to shift 64 to the right by the granularity. This operation is
undefined if the granularity is greater than 57. Adding an assertion is
fine for now, because serializing is done only in tests so far, but this
means that only bitmaps with a granularity below 58 can be serialized
and we should thus add a hbitmap_is_serializable() function later.

One of the two places touched in this patch uses
QEMU_ALIGN_UP(x, 1 << y). We can use ROUND_UP() there, since the second
parameter is obviously a power of two.

pci-assign: sync MSI/MSI-X cap and table with PCIDevice

Since commit e1d4fb2d ("kvm-irqchip: x86: add msi route notify fn"),
kvm_irqchip_add_msi_route() starts to use pci_get_msi_message() to fetch
MSI info. This requires that we setup MSI related fields in PCIDevice.
For most devices, that won't be a problem, as long as we are using
general interfaces like msi_init()/msix_init().

However, for pci-assign devices, MSI/MSI-X is treated differently - PCI
assign devices are maintaining its own MSI table and cap information in
AssignedDevice struct. however that's not synced up with PCIDevice's
fields. That will leads to pci_get_msi_message() failed to find correct
MSI capability, even with an NULL msix_table.

A quick fix is to sync up the two places: both the capability bits and
table address for MSI/MSI-X.

Commit 8cc4678 ("megasas: remove useless check for cmd->frame", 2016-07-17) was
wrong because I trusted Coverity too much.  It turns out that there _is_ a
path through which cmd->frame can become NULL.  After megasas_handle_frame's
switch (md->frame->header.frame_cmd), megasas_init_firmware can be called.
From there, megasas_reset_frames will call megasas_unmap_frame which resets
cmd->frame = NULL.

However, there is another bug to fix in there, because megasas_unmap_frame
is called again after setting the command status.  In this case QEMU should
not do anything, instead it calls pci_dma_unmap again.  Harmless, but

ppc patch queue 2016-11-23

Here's the first set of 2.8 hard freeze bugfixes for ppc.

The biggest thing here is a batch of fixes for migration breakages in
both 2.7 and current 2.8.  Alas, there is at least one more migration
problem, which prevents memory unplug after a migration.  I hoped to
include a fix for that here, but it turned out to have some problems
bigger than those it was solving.  So, I expect at least one more hard
freeze pull request.

There are also a few other assorted bug fixes.

7 years agospapr: Fix 2.7<->2.8 migration of PCI host bridge
David Gibson [Tue, 22 Nov 2016 23:26:38 +0000 (10:26 +1100)]
spapr: Fix 2.7<->2.8 migration of PCI host bridge

daa2369 "spapr_pci: Add a 64-bit MMIO window" subtly broke migration
from qemu-2.7 to the current version.  It split the device's MMIO
window into two pieces for 32-bit and 64-bit MMIO.

The patch included backwards compatibility code to convert the old
property into the new format.  However, the property value was also
transferred in the migration stream and compared with a (probably
unwise) VMSTATE_EQUAL.  So, the "raw" value from 2.7 is compared to
the new style converted value from (pre-)2.8 giving a mismatch and
migration failure.

Along with the actual field that caused the breakage, there are
several other ill-advised VMSTATE_EQUAL()s.  To fix forwards
migration, we read the values in the stream into scratch variables and
ignore them, instead of comparing for equality.  To fix backwards
migration, we populate those scratch variables in pre_save() with
adjusted values to match the old behaviour.

To permit the eventual possibility of removing this cruft from the
stream, we only include these compatibility fields if a new
'pre-2.8-migration' property is set.  We clear it on the pseries-2.8
machine type, which obviously can't be migrated backwards, but set it
on earlier machine type versions.
