tpm.c: Don't try to put -1 in a variable of type TpmModel
The TpmModel type is an enum (valid values 0 and 1), which means
the compiler can legitimately decide that comparisons like
'tpm_models[i] == -1' are never true. (For example it could
pick 'unsigned char' as its type for representing the enum.)
Avoid this issue by using TPM_MODEL_MAX to mark entries in
the tpm_models[] array which aren't filled in, instead of -1.

The driver calculates SOLNT bit from UCSOLNT and SCSOLNT bits from

xics: rename types to be sane and follow coding style
Basically, in HW the layout of the interrupt network is:
- One ICP per processor thread (the "presenter"). This contains the
registers to fetch a pending interrupt (ack), EOI, and control the
processor priority.
- One ICS per logical source of interrupts (ie, one per PCI host
bridge, and a few others here or there). This contains the per-interrupt
source configuration (target processor(s), priority, mask) and the
per-interrupt internal state.
Under PAPR, there is a single "virtual" ICS ... somewhat (it's a bit
oddball what pHyp does here, arguably there are two but we can ignore
that distinction). There is no register level access. A pair of firmware
(RTAS) calls is used to configure each virtual interrupt.
So our model here is somewhat the same. We have one ICS in the emulated
XICS which arguably *is* the emulated XICS, there's no point making it a
separate "device", that would just be gross, and each VCPU has an
associated ICP.
Yet we call the "XICS" struct icp_state and then the ICPs
'struct icp_server_state'. It's particularly confusing when all of the
functions have xics_prefixes yet take *icp arguments.
Rename:
struct icp_state -> XICSState
struct icp_server_state -> ICPState
struct ics_state -> ICSState
struct ics_irq_state -> ICSIRQState

pseries: savevm support for pseries machine
This adds the necessary pieces to implement savevm / migration for the
pseries machine. The most complex part here is migrating the hash
table - for the paravirtualized pseries machine the guest's hash page
table is not stored within guest memory, but externally and the guest
accesses it via hypercalls.
This patch uses a hypervisor reserved bit of the HPTE as a dirty bit
(tracking changes to the HPTE itself, not the page it references).
This is used to implement a live migration style incremental save and
restore of the hash table contents.
Normally a hash table is 16MB but it can get bigger depending on how
much RAM the guest has. Due to its nature, updates to it are random so
the live migration style is used for it.
In addition it adds VMStateDescription information to save and restore
the (few) remaining pieces of state information needed by the pseries
machine.

mips_malta: generate SMBUS EEPROM data
The malta contains 2 EEPROMs, one containing SPD data for the SDRAM and
another containing board information such as serial number and MAC
address. These are both exposed via the PIIX4 SMBUS. Generating this
data and providing it to smbus_eeprom_init will allow YAMON to read a
serial number for the board and prevent it from warning that the EEPROM
data is invalid.
We already have the contents of the SPD EEPROM which are exposed via
FPGA I2C accesses, this is provided as part of the SMBUS EEPROM data
too for consistency.

mips_malta: generate SPD EEPROM data at runtime
The SPD EEPROM specifies the amount of memory present in the system and
thus its correct contents can only be known at runtime. Calculating
parts of the data on init allows the data to accurately reflect the
amount of target memory present and allow YAMON to boot with an
arbitrary amount of SDRAM.
Where possible the SPD data will favor indicating 2 banks of SDRAM
rather than 1. For example the default 128MB of target memory will be
represented as 2x64MB banks rather than 1x128MB bank. This allows
versions of MIPS BIOS code (such as YAMON 2.22 and older) to boot
despite a bug preventing them from handling a single bank of SDRAM with
the Galileo GT64120 system controller emulated by QEMU.

mips_malta: correct reading MIPS revision at 0x1fc00010
Rather than modifying the BIOS code at its original location, copy it
for the 0x1fc00000 region & modify the copy. This means the original
ROM code is correctly readable at 0x1e000010 whilst the MIPS revision
is readable at 0x1fc00010.
Additionally the code previously operated on target memory which would
later be overwritten by the BIOS image upon CPU reset if the -bios
argument was used to specify the BIOS image. This led to the written
MIPS revision being lost. Copying using rom_copy when -bios is used
fixes this issue.

mips_malta: fix BIOS endianness swapping
If the target is little endian (mipsel) then the BIOS image endianness
is swapped so that the big endian BIOS binaries commonly produced can be
loaded correctly.
When using the -bios argument the BIOS is loaded using
load_image_targphys, however this doesn't perform the load to target
memory immediately. Instead it loads the BIOS file into a struct Rom
which will later be written to target memory upon reset. However the
endianness conversion was being performed before this, on init, and
operating on the target memory which at this point is blank & will later
be overwritten by the (big endian) BIOS image. Correct this by operating
on the data referenced by struct Rom rather than the target memory when
the -bios argument is used.

target-mips: fix branch in likely delay slot tcg assert
When a branch delay slot contains another branch instruction, the code
generated raises an exception, however since is_branch==1,
handle_delay_slot() doesn't get called immediately. This means
ctx->bstate isn't set to BS_BRANCH, and the decoder continues decoding
until a non-branch instruction is found.
If the first branch was a branch likely instruction then each
instruction after it generates code for the unlikely case, to go to the
next tb starting after the delay slot. This results in multiple goto_tb
tcg ops being generated with the same exit number. When debug is enabled
this hits:
tcg-op.h:2589: tcg_gen_goto_tb: Assertion `(tcg_ctx.goto_tb_issue_mask & (1 << idx)) == 0' failed.
This is fixed by removing is_branch entirely, and calling
handle_delay_slot() if (ctx.hflags & MIPS_HFLAG_BMASK) was set prior to
the current instruction being decoded. This still prevents
handle_delay_slot() being called immediately after a branch but allows
it to still be called after a branch within a delay slot.

Implement sync modes for drive-backup.
This patch adds sync-modes to the drive-backup interface and
implements the FULL, NONE and TOP modes of synchronization.
FULL performs as before copying the entire contents of the drive
while preserving the point-in-time using CoW.
NONE only copies new writes to the target drive.
TOP copies changes to the topmost drive image and preserves the
point-in-time using CoW.
For sync mode TOP are creating a new target image using the same backing
file as the original disk image. Then any new data that has been laid
on top of it since creation is copied in the main backup_run() loop.
There is an extra check in the 'TOP' case so that we don't bother to copy
all the data of the backing file as it already exists in the target.
This is where the bdrv_co_is_allocated() is used to determine if the
data exists in the topmost layer or below.
Also any new data being written is intercepted via the write_notifier
hook which ends up calling backup_do_cow() to copy old data out before
it gets overwritten.
For mode 'NONE' we create the new target image and only copy in the
original data from the disk image starting from the time the call was
made. This preserves the point in time data by only copying the parts
that are *going to change* to the target image. This way we can
reconstruct the final image by checking to see if the given block exists
in the new target image first, and if it does not, you can get it from
the original image. This is basically an optimization allowing you to
do point-in-time snapshots with low overhead vs the 'FULL' version.
Since there is no old data to copy out the loop in backup_run() for the
NONE case just calls qemu_coroutine_yield() which only wakes up after
an event (usually cancel in this case). The rest is handled by the
before_write notifier which again calls backup_do_cow() to write out
the old data so it can be preserved.

blockdev: Split up 'cache' option
The old 'cache' option really encodes three different boolean flags into
a cache mode name, without providing all combinations. Make them three
separate options instead and translate the old option to the new ones
for drive_init().
The specific boolean options take precedence if the old cache option is
specified as well, so the following options are equivalent:
-drive file=x,cache=none,cache.no-flush=true
-drive file=x,cache.writeback=true,cache.direct=true,cache.no-flush=true

The discriminator for anonymous unions is the data type. This allows to
