0e21f183ca hw/arm/virt: Enable TZ extensions on the GIC if we are using them
If we're creating a board with support for TrustZone, then enable
it on the GIC model as well as on the CPUs.

2d710006a0 hw/arm/virt: Default to not providing TrustZone support
Switch the default for the 'virt' board to not providing TrustZone
support in either the CPU or the GIC. This is primarily for the
benefit of UEFI, which currently assumes there is no TrustZone
support, and does not set the GIC up correctly if it is TZ-aware.
It also means the board is consistent about its behaviour whether
we're using KVM or TCG (KVM never has TrustZone support).

If TrustZone support is required (for instance for running test
suites or TZ-aware firmware) it can be enabled with the
"-machine secure=on" command line option.

8ff41f3995 hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel boot
If we directly boot a kernel in NonSecure on a system where the GIC
supports the security extensions then we must cause the GIC to
configure its interrupts into group 1 (NonSecure) rather than the
usual group 0, and with their initial priority set to the highest
NonSecure priority rather than the usual highest Secure priority.
Otherwise the guest kernel will be unable to use any interrupts.

Implement this behaviour, controlled by a flag which we set if
appropriate when the ARM bootloader code calls our ARMLinuxBootIf
interface callback.

d8b1ae4237 hw/arm: new interface for devices which need to behave differently for kernel boot
For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)

Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

d5523a1365 hw/intc/arm_gic: Actually set the active bits for active interrupts
Although we were correctly handling interrupts becoming active
and then inactive, we weren't actually exposing this to the guest
by setting the 'active' flag for the interrupt, so reads
of GICD_ICACTIVERn and GICD_ISACTIVERn would generally incorrectly
return zeroes. Correct this oversight.

72889c8a80 hw/intc/arm_gic: Drop running_irq and last_active arrays
The running_irq and last_active arrays represent state which
doesn't exist in a real hardware GIC. The only thing we use
them for is updating the running priority when an interrupt
is completed, but in fact we can use the active-priority
registers to do this. The running priority is always the
priority corresponding to the lowest set bit in the active
priority registers, because only one interrupt at any
particular priority can be active at once.

51fd06e0ee hw/intc/arm_gic: Fix handling of GICC_APR<n>, GICC_NSAPR<n> registers
A GICv2 has both GICC_APR<n> and GICC_NSAPR<n> registers, with
the latter holding the active priority bits for Group 1 interrupts
(usually Nonsecure interrupts), and the Nonsecure view of the
GICC_APR<n> is the second half of the GICC_NSAPR<n> registers.
Turn our half-hearted implementation of APR<n> into a proper
implementation of both APR<n> and NSAPR<n>:

 * Add the underlying state for NSAPR<n>
 * Make sure APR<n> aren't visible for pre-GICv2
 * Implement reading of NSAPR<n>
 * Make non-secure reads of APR<n> behave correctly
 * Implement writing to APR<n> and NSAPR<n>

df92cfa60e hw/intc/arm_gic: Running priority is group priority, not full priority
Priority values for the GIC are divided into a "group priority"
and a "subpriority" (with the division being determined by the
binary point register). The running priority is only determined
by the group priority of the active interrupts, not the
subpriority. In particular, this means that there can't be more
than one active interrupt at any particular group priority.

732bdd383e s390/sclp: temporarily fix unassignment/reassignment of memory subregions
Commit 374f2981d1 ("memory: protect current_map by RCU") broke
unassignment of standby memory on s390x. Looks like that the new
parallelism allows races with our (semi broken) memory hotplug code. The
flatview_unref() can now be executed after our unparenting. Therefore
memory_region_unref() tries to unreference the MemoryRegion itself instead
of the parent.

In theory, MemoryRegions are now bound to separate devices that control
their lifetime. We don't have this yet, so we really want to control their
lifetime manually.

This patch fixes it temporarily, until we have a proper rework. The only
drawback is that they won't pop up in "info qom-tree", but that's better
than qemu crashes.

We have to release the reference to a memory region after a
memory_region_find, as it automatically takes a reference. As we're now
able to reassign memory, the MemoryRegion is in fact deleted (otherwise
vmstate_register_ram() would complain).

f6102c329c s390/sclp: rework sclp event facility initialization + device realization
The current code only works by chance. The event facility is a sysbus
device, but specifies in its class structure as parent the DeviceClass
(instead of a device class).

The init function in return lies therefore at the same position as
the init function of SysBusDeviceClass and gets triggered instead -
a very bad idea of doing that (e.g. the parameter types don't match).

Let's bring the initialization code up to date, initializing the event
facility + child events in .instance_init and moving the realization of
the child events out of the init call, into the realization step.

Device realization is now automatically performed when the event facility
itself is realized. That realization implicitly triggers realization of
the child bus, which in turn initializes the events.

Please note that we have to manually propagate the realization of the bus
children, common code still has a TODO set for that task.

c0194a00b0 s390x/kvm: make setting of in-kernel irq routes more efficient
When we add new adapter routes we call kvm_irqchip_add_route() for every
virtqueue and in the same step also do the KVM_SET_GSI_ROUTING ioctl.

This is unnecessary costly as the interface allows us to set multiple
routes in one go. Let's first add all routes to the table stored in the
global kvm_state and then do the ioctl to commit the routes to the
in-kernel irqchip.

This saves us several ioctls to the kernel where for each call a list
is reallocated and populated.

6b7741c2be s390x/css: start with cleared cstat/dstat
When executing the start function, we should start with a clear state
regarding subchannel and device status; it is easy to forget updating one
of them after the ccw has been processed.

Note that we don't need to care about resetting the various control
fields: They are cleared by tsch(), and if they were still pending,
we wouldn't be able to execute the start function in the first
place.

Also note that we don't want to clear cstat/dstat if a suspended
subchannel is resumed.

This fixes a bug where we would continue to present channel-program
check in cstat even though later ccw requests for the subchannel
finished without error (i.e. cstat should be 0).

fde8206b80 s390x/css: handle ccw-0 TIC correctly
In CCW-0 format TIC command 4 highest bits are ignored in the subchannel.
In CCW-1 format the TIC command 4 highest bits must be 0.
To convert TIC from CCW-0 to CCW-1 we clear the 4 highest bits
to guarantee compatibility.

9bff5d8135 hw/pci: Use pow2ceil() rather than hand-calculation
A couple of places in hw/pci use an inline calculation to round a
size up to the next largest power of 2. We have a utility routine
for this, so use it.

(The behaviour of the old code is different if the size value
is 0 -- it would leave it as 0 rather than rounding up to 1,
but in both cases we know the size can't be 0.
In the case where the size value had bit 31 set, the old code
would invoke undefined behaviour; the new code will give a
result of 0. Presumably that could never happen either.)

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

if it's not ready, removing the .can_receive callback avoids the
necessity to add explicit flushes when the conditions turn true (which

"net/socket: Drop net_socket_can_send").

Plus the "return 1" if E8390_STOP is also suspicious.

by making sure that packet_size + 8 does not exceed the
available buffer space.  The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update.  So it is possible that
every packet ends up being slightly padded when written
to the receive buffer.  This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.

This patch takes alignment into consideration when
checking for overflow condition.

e402463073 pci: allow 0 address for PCI IO/MEM regions
Some kernels program a 0 address for io regions. PCI 3.0 spec
section 6.2.5.1 doesn't seem to disallow this.

based on patch by Michael Roth <mdroth@linux.vnet.ibm.com>

Add pci_allow_0_addr in MachineClass to conditionally
allow addr 0 for pseries, as this can break other architectures.

This patch allows to hotplug PCI card in pseries machine, as the first
added card BAR0 is always set to 0 address.

This as a temporary hack, waiting to fix PCI memory priorities for more
machine types...

isaps and xenfv. Both were already overwriting max_cpus, and only isapc
was not overwriting hot_add_cpu.

After making isapc set hot_add_cpu to NULL, we can move the
pc_default_machine_options() code the PC common class_init.

e33d22fab3 piix: Document coreboot-specific RAM size config register
The existing i440fx initialization code sets a PCI config register that
isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is
DRAMC (DRAM Control) and has nothing to do with the RAM size.

This was implemented in commit ec5f92ce6a
because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to
get the RAM size from QEMU, but I couldn't find out why coreboot did
that. I assume it was a mistake, and the original code was supposed to
be reading the DRB[0-7] registers (offsets 0x60-0x67).

Document that coreboot-specific register offset in a macro and a
comment, for future reference.

27fa747980 make: load only required dependency files.
The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.

This patch fixes this by
  - loading precise list of .d files made from *.o and *.mo.
  - specifying explicit list of required dependency info files for
     *.hex autogenerated sources.

Note that Makefile still includes some .d in root directory by including
"*.d".

998b7b1db4 make: fix where dependency *.d are stored.
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'.  It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.

As a hack, we also touch two sources for generated *.hex files.  Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

Transmit offload needs to parse packet headers.  If header fields have
unexpected values the offload processing is skipped.

The code currently uses nested ifs because there is relatively little
input validation.  The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.

0e826a061a macio: re-add TRIM support
Commit bd4214fc dropped TRIM support by mistake. Given it is still
advertised to the host when using a drive with discard=on, this cause
the IDE bus to hang when the host issues a TRIM command.

This patch fixes that by re-adding the TRIM code, ported to the new
new DMA implementation.

af103c9310 vhost/scsi: call vhost_dev_cleanup() at unrealize() time
vhost-scsi calls vhost_dev_init() at realize() time
but forgets to call it's counterpart vhost_dev_cleanup()
at unrealize() time.

Calling it should fix leaking of memory table and
mem_sections table in vhost device. And also unregister
vhost's memory listerner to prevent access from
memory core to freed memory.

a56537a127 scsi-disk: Fix assertion failure on WRITE SAME
The last portion of an unaligned WRITE SAME command could fail the
assertion in bdrv_aligned_pwritev:

    assert(!qiov || bytes == qiov->size);

Because we updated data->iov.iov_len right above this if block, but
data->qiov still has the old size.

Reinitialize the qiov to make them equal and keep block layer happy.

ff1d2ac949 hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.

Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.

[Fixed coding style: 4-space indent and curly braces on if statement.

55875fc4ca megasas: Add write function to handle write access to PCI BAR 3
This patch fixes a QEMU SEGFAULT when a write operation is performed on
the memory region of the PCI BAR 3 (base address space).
When a writeb(0xe0000000) is performed the .write function is invoked to
handle the write access, however, since the .write is not initialised,
the call to 0, causes QEMU to SEGFAULT.
