spice: fix memory leak
If errors happen for middle items of channel_list,
qmp_query_spice_channels() returns NULL, and the variable
cur_item going out of scope leaks the storage it points to.
The flag is a compatibility thing for older spice-server
versions. Meanwhile our minimum spice version requirement is
new enough that we should never ever see this error, and if we
do something went very seriously wrong. Let's using assert()
instead of returning NULL to avoid a memory leak.

Add fast path to qemu_spice_display_switch in case old and new

spice: reduce refresh rate in native mode
Now that cursor updates are out of the way qxl needs the refresh timer
only when when running in vga mode, for dirty bitmap checking. In
native qxl mode the guest will notify us, so we don't need to poll and
can use the idle interval (one refresh wakeup every few seconds).
Gerd Hoffmann [Tue, 4 Nov 2014 12:59:59 +0000 (13:59 +0100)]
spice: use bottom half instead of refresh timer for cursor updates
Calling directly doesn't work due to the qxl-render code running in
spice server thread context. Meanwhile bottom half scheduling is
thread-safe though, so we can use that to kick a cursor update in
main i/o thread context.
Now we've got multiple QEMUFile source files, some of them need
access to things that were defined in qemu-file.c, so create
a -internal header for them.
Start migrating migration code into a migration directory
The migration code now occupies a fair chunk of the top level .c
files, it seems time to give it it's own directory.
I've not touched:
arch_init.c - that's mostly RAM migration but has a few random other
bits
savevm.c - because it's built target specific
This is purely a code move; no code has changed.
- it fails checkpatch because of old violations, it feels safer
to keep this as purely a move and fix those at some mythical future
date.
The xbzrle and vmstate tests are now only run for softmmu builds
since they require files in the migrate/ directory which is only built
for softmmu.

serial: only resample THR interrupt on rising edge of IER.THRI
There is disagreement on whether LSR.THRE should be resampled when
IER.THRI goes from 1 to 1. Bochs only does it if IER.THRI goes from 0
to 1; PCE does it even if IER.THRI is unchanged. But the Windows driver
seems to always go from 1 to 0 and back to 1, so do things in agreement
with Bochs, because the handling of thr_ipending was reported in 2010
(https://lists.gnu.org/archive/html/qemu-devel/2010-03/msg01914.html)

serial: update LSR on enabling/disabling FIFOs
When the transmit FIFO is emptied or enabled, the transmitter
hold register is empty. When it is disabled, it is also emptied and
in addition the previous contents of the transmitter hold register
are discarded. In either case, the THRE bit in LSR must be set and
THRI raised.
When the receive FIFO is emptied or enabled, the data ready and break
bits must be cleared in LSR. Likewise when the receive FIFO is disabled.
Paolo Bonzini [Thu, 11 Dec 2014 16:01:39 +0000 (17:01 +0100)]
serial: clean up THRE/TEMT handling
- assert TEMT is cleared before sending a character; we'll get one from
TSR if tsr_retry > 0, from the FIFO or THR otherwise
- assert THRE cleared and FIFO not empty (if enabled) before fetching a
character to send. This effectively reverts dffacd46, but the check
makes no sense and commit f702e62 (serial: change retry logic to avoid
concurrency, 2014-07-11) must have made it unnecessary. The commit
message for f702e62 talks about multiple calls to qemu_chr_fe_add_watch
triggering s->tsr_retry >= MAX_XMIT_RETRY, but other failures were
possible. For example, if you have multiple calls, the subsequent ones
will see s->tsr_retry == 0 and will find THRE and/or TEMT on entry.
- for clarity, raise THRI immediately after the code sets THRE
- check THRE to see if another character has to be sent. This makes
the assertions more obvious and also means TEMT has to be set as soon as
the loop ends. It makes the loop send both TSR and THR if flow-control
happens in non-FIFO mode. Previously, THR would be lost.
- clear TEMT together with THRE even in the non-FIFO case
The last two items are bugfixes, but they were just found by inspection
and do not squash known bugs.

serial: reset thri_pending on IER writes with THRI=0
This is responsible for failure of migration from 2.2 to 2.1, because
thr_ipending is always one in practice.
serial.c is setting thr_ipending unconditionally. However, thr_ipending
is not used at all if THRI=0, and it will be overwritten again the next
time THRE or THRI changes. For that reason, we can set thr_ipending to
zero every time THRI is reset.
There is disagreement on whether LSR.THRE should be resampled when IER.THRI
goes from 1 to 1. This patch does not touch the code, leaving that for
QEMU 2.3+.
This has no semantic change and is enough to fix migration in the common
case where the interrupt is not pending or is reported in IIR. It does not
change the migration format, so 2.2.0 -> 2.1 will remain broken but we
can fix 2.2.1 -> 2.1 without breaking 2.2.1 <-> 2.2.0.
The case that remains broken (the one in which the subsection is strictly
necessary) is when THRE=1, the THRI interrupt has *not* been acknowledged
yet, and a higher-priority interrupt comes. In this case, you need the
subsection to tell the source that the lower-priority THRI interrupt is
pending. The subsection's breakage of migration, in this case, prevents
continuing the VM on the destination with an invalid state.

linuxboot: fix loading old kernels
Old kernels that used high memory only allowed the initrd to be in the
first 896MB of memory. If you load the initrd above, they complain
that "initrd extends beyond end of memory".
In order to fix this, while not breaking machines with small amounts
of memory fixed by cdebec5 (linuxboot: compute initrd loading address,
2014-10-06), we need to distinguish two cases. If pc.c placed the
initrd at end of memory, use the new algorithm based on the e801
memory map. If instead pc.c placed the initrd at the maximum address
specified by the bzImage, leave it there.
The only interesting part is that the low-memory info block is now
loaded very early, in real mode, and thus the 32-bit address has
to be converted into a real mode segment. The initrd address is
also patched in the info block before entering real mode, it is
simpler that way.
This fixes booting the RHEL4.8 32-bit installation image with 1GB
of RAM.

target-arm queue:
* pass semihosting exit code out to system
* more TrustZone support code (still not enabled yet)
* allow user to direct semihosting to gdb or native explicitly
rather than always auto-guessing the destination
* fix memory leak in realview_init
* fix coverity warning in hw/arm/boot
* get state migration working for AArch64 CPUs
* check errors in kvm_arm_reset_vcpu

target-arm: Check error conditions on kvm_arm_reset_vcpu
When resetting a VCPU we currently call both kvm_arm_vcpu_init() and
write_kvmstate_to_list(), both of which can fail, but we never check the
return value.
The only choice here is to print an error an exit if the calls fail.

target-arm: Support save/load for 64 bit CPUs
For migration to work on 64 bit CPUs, we need to include both
the 64-bit integer register file and the PSTATE. Everything
else is either stored in the same place as existing 32-bit CPU
state or handled by the generic sysreg mechanism.
