Peter Maydell 58d479786b hw/pci-host/bonito: Avoid buffer overrun for bad LDMA/COP accesses
The LDMA and COP memory regions represent four 32 bit registers
each, but the memory regions themselves are 0x100 bytes large.
Add guards to the read and write accessors so that bogus accesses
beyond the four defined registers don't just run off the end of
the bonldma and boncop structs and into whatever lies beyond.

Eduardo Habkost 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.

Juan Quintela 5cd8cadae8 migration: Use normal VMStateDescriptions for Subsections
We create optional sections with this patch.  But we already have
optional subsections.  Instead of having two mechanism that do the
same, we can just generalize it.

For subsections we just change:

- Add a needed function to VMStateDescription
- Remove VMStateSubsection (after removal of the needed function
  it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding
  VMStateDescription

Gerd Hoffmann bafc90bdc5 q35: implement TSEG
TSEG provides larger amounts of SMRAM than the 128 KB available with
legacy SMRAM and high SMRAM.

Route access to tseg into nowhere when enabled, for both cpus and
busmaster dma, and add tseg window to smram region, so cpus can access
it in smm mode.

Once the SMRAM.D_LCK bit has been set by the guest several bits in SMRAM
and ESMRAMC become readonly until the next machine reset.  Implement
this by updating the wmask accordingly when the guest sets the lock bit.
As the lock it itself is locked down too we don't need to worry about

Paolo Bonzini 64130fa4a1 q35: implement high SMRAM
When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at

by D_OPEN and the SMM view controlled by G_SMRAME, so add two new

Paolo Bonzini fe6567d5fd hw/i386: add a separate region that tracks the SMRAME bit
This region is exported at /machine/smram.  It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1.  The CPU will
enable/disable it as it enters or exits SMRAM.

While touching nearby code, the existing memory region setup was
slightly inconsistent.  The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000).  Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

With simple exposure of MMFG, ioport window, mmio window and an IRQ line we
can successfully create a workable PCIe host bridge that can be mapped anywhere

This patch implements such a "generic" host bridge. It handles 4 legacy IRQ
lines. MSIs need to be handled external to the host bridge.

Alexander Graf cb3778a045 PPC: e500 pci host: Add support for ATMUs
The e500 PCI controller has configurable windows that allow a guest OS
to selectively map parts of the PCI bus space to CPU address space and
to selectively map parts of the CPU address space for DMA requests into
PCI visible address ranges.

So far, we've simply assumed that this mapping is 1:1 and ignored it.

However, the PCICSRBAR (CCSR mapped in PCI bus space) always has to live
inside the first 32bits of address space. This means if we always treat
all mappings as 1:1, this map will collide with our RAM map from the CPU's
point of view.

So this patch adds proper ATMU support which allows us to keep the PCICSRBAR
below 32bits local to the PCI bus and have another, different window to PCI
BARs at the upper end of address space. We leverage this on e500plat though,
mpc8544ds stays virtually 1:1 like it was before, but now also goes via ATMU.

With this patch, I can run guests with lots of RAM and not coincidently access
MSI-X mappings while I really want to access RAM.

Pavel Dovgalyuk 2c9ecdeb9f piix: do not set irq while loading vmstate
This patch avoids setting an irq while loading the state of the ISA bridge.
Because the i8259 has not been deserialized yet, raising an interrupt
could bring the system out-of-sync with the migration source.  For example,
the migration source could have masked the interrupt in the i8259. On the
destination, the i8259 device model would not know that yet and would
trigger an interrupt in the CPU.

This patch eliminates setting the irq and just restores the calculated
state fields in post_load function.  Interrupt state will be deserialized
separately through the IRR field of the i8259.

Le Tan a52a7fdfa7 intel-iommu: add Intel IOMMU emulation to q35 and add a machine option "iommu" as a switch
Add Intel IOMMU emulation to q35 chipset and expose it to the guest.
1. Add a machine option. Users can use "-machine iommu=on|off" in the command
line to enable/disable Intel IOMMU. The default is off.
2. Accroding to the machine option, q35 will initialize the Intel IOMMU and
use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for
the pci bus.
3. q35_host_dma_iommu() will return different address space according to the
bus_num and devfn of the device.

The array regs is declared with IOMMU_NREGS (3) elements and accessed
using IOMMU_CTRL (0) and IOMMU_BASE (8). In most cases, those values
are right shifted before being used as an index which results in indices
0 and 1. In one case, this right shift was missing for IOMMU_BASE which
results in an out-of-bounds write access with index 8.

The patch adds the missing shift operation also for IOMMU_CTRL where
it is needed only for cosmetic reasons.

Peter Maydell 7dc176bce4 hw/pci-host/prep: Don't reverse IO accesses on bigendian hosts
The raven_io_read() and raven_io_write() functions pass and
return values in little-endian format (since the IO op struct
is marked DEVICE_LITTLE_ENDIAN); however they were storing the
values in the buffer to pass to address_space_read/write()
in host-endian order, which meant that on big-endian hosts
the values were inadvertently reversed. Use the *_le_p()
accessors instead so that we are consistent regardless of
host endianness.

Strictly speaking the byte order of the buffer for
address_space_rw() is target byte order (which for PPC
will be BE) but it doesn't actually matter as long as we
are consistent about the marking on the IO op struct and
which stl_*_p().

This bug was probably introduced due to confusion caused by
the two different versions of ldl_p() and friends:
 bswap.h defines versions meaning "host endianness access"
 cpu-all.h defines versions meaning "target endianness access"
As a target-independent source file prep.c gets the bswap.h
versions; the very similar looking code in ioport.c is
compiled per-target and gets the cpu-all.h versions.

In write-only mode, writes are forwarded to RAM, while reads should not be

Assume that in this mode, no read access is ever done, as they shouldn't
give any sensible result.

So, in write-only mode, alias PAM region to RAM, instead of PCI memory
(which can even be mapped to some device!)

This fixes Award BIOS, which use this mode to shadow system BIOS and video BIOS.

Gerd Hoffmann ddaaefb4dd piix: fix 32bit pci hole
Make the 32bit pci hole start at end of ram, so all possible address
space is covered.

We used to try and make addresses aligned so they are easier to cover
with MTRRs, but since they are cosmetic on KVM, this is probably not
worth worrying about.
Of course the firmware can use less than that.  Leaving space unused is
no problem, mapping pci bars outside the hole causes problems though.

Markus Armbruster 81aab2ff11 piix3 piix4: Clean up use of cannot_instantiate_with_device_add_yet
A PIIX3/PIIX4 southbridge has multiple functions.  We model each
function as a separate qdev.  Two of them need some special wiring set
up in pc_init1() or mips_malta_init() to work: the ISA bridge at 01.0,
and the SMBus controller at 01.3.

The IDE controller at 01.1 (piix3-ide, piix3-ide-xen, piix4-ide) has
always had cannot_instantiate_with_device_add_yet set, but there is no
obvious reason why device_add could not work for them.  Drop it.

Markus Armbruster 08c58f92f6 pci-host: Consistently set cannot_instantiate_with_device_add_yet
Many PCI host bridges consist of a sysbus device and a PCI device.
You need both for the thing to work.  Arguably, these bridges should
be modelled as a single, composite devices instead of pairs of
seemingly independent devices you can only use together, but we're not
there, yet.

Since the sysbus part can't be instantiated with device_add, yet,
permitting it with the PCI part is useless.  We shouldn't offer
useless options to the user, so let's set
cannot_instantiate_with_device_add_yet for them.

It's already set for Bonito, Grackle, i440FX and Raven.  Document why.

Set it for the others: dec-21154, e500-host-bridge, gt64120_pci, mch,
pbm-pci, ppc4xx-host-bridge, sh_pci_host, u3-agp, uni-north-agp,
uni-north-internal-pci, uni-north-pci, and versatile_pci_host.

Markus Armbruster 837d37167d sysbus: Set cannot_instantiate_with_device_add_yet
device_add plugs devices into suitable bus.  For "real" buses, that
actually connects the device.  For sysbus, the connections need to be
made separately, and device_add can't do that.  The device would be
left unconnected, and could not possibly work.

Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.

Set it in their abstract base's class init function
sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

Markus Armbruster efec3dd631 qdev: Replace no_user by cannot_instantiate_with_device_add_yet
In an ideal world, machines can be built by wiring devices together
with configuration, not code.  Unfortunately, that's not the world we
live in right now.  We still have quite a few devices that need to be
wired up by code.  If you try to device_add such a device, it'll fail
in sometimes mysterious ways.  If you're lucky, you get an
unmysterious immediate crash.

To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad.  The device model is still omitted from
help, but is available anyway.

Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.

This commit clarifies no_user's purpose.  Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy.  While there, make it
bool.

Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale.  The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.

With that done, the regression fix is hopefully acceptable.

Alexander Graf 8a0e11045d PPC: Use default pci bus name for grackle and heathrow
There's no good reason to call our bus "pci" rather than let the default
bus name take over ("pci.0").

The big downside to calling it different from anyone else is that tools
that pass -device get confused. They are looking for a bus "pci.0" rather
than "pci".

To make life easier for everyone, let's just drop the name override.

Cole Robinson 04c7d8b8de Fix pc migration from qemu <= 1.5
The following commit introduced a migration incompatibility:

commit 568f0690fd
Author: David Gibson <david@gibson.dropbear.id.au>
Date:   Thu Jun 6 18:48:49 2013 +1000

    pci: Replace pci_find_domain() with more general pci_root_bus_path()

The issue is that i440fx savevm idstr went from 0000:00:00.0/I440FX to
0000:00.0/I440FX. Unfortunately we are stuck with the breakage for
1.6 machine types.

Add a compat property to maintain the busted idstr for the 1.6 machine
types, but revert to the old style format for 1.7+, and <= 1.5.

Tested with migration from qemu 1.5, qemu 1.6, and qemu.git.

commit 3984890181
    pc: limit 64 bit hole to 2G by default
introduced a way for management to control
the window allocated to the 64 bit PCI hole.

This is useful, but existing management tools do not know how to set
this property.  As a result, e.g. specifying a large ivshmem device with
size > 4G is broken by default.  For example this configuration no
longer works:

-device ivshmem,size=4294967296,chardev=cfoo
-chardev socket,path=/tmp/sock,id=cfoo,server,nowait

Fix this by detecting that hole size was not specified
and defaulting to the backwards-compatible value of 1 << 62.
