Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().
Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().
Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:
nr -bios -pflash -kernel description
unit#0
-- ------- ------- ------- -------------------------------------------
1 present present absent Board code rejects this case, -bios and
present present present -pflash unit#0 are exclusive. Left intact
by this patch.
2 absent absent present Traditional kernel loading, with qemu's
minimal board firmware. Left intact by this
patch.
3 absent present absent Preexistent case for booting guest firmware
present absent absent loaded with -bios or -pflash. Left intact
by this patch.
4 absent absent absent Preexistent case for not loading any
firmware or kernel up-front. Left intact by
this patch.
5 present absent present New case introduced by this patch: kernel
absent present present image is passed to externally loaded
firmware in unmodified form, using fw_cfg.
An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

We rebase fw_cfg_init_mem() to the new function for compatibility with
current callers.
The behavior of the (big endian) multi-byte data reads is best shown
with a qtest session. Here, we are reading the first six bytes of
the UUID
$ arm-softmmu/qemu-system-arm -M virt -machine accel=qtest \
-qtest stdio -uuid 4600cb32-38ec-4b2f-8acb-81c6ea54f2d8
>>> writew 0x9020008 0x0200
<<< OK
>>> readl 0x9020000
<<< OK 0x000000004600cb32
Remember this is big endian. On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.
On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046. When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.
Reading byte-by-byte works too, of course:
>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec
Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.
However we don't want to touch the I/O port mapped fw_cfg device at all.
Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.
Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.
TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)
TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.
The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.
The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

The commits:
- 6a1fa9f5 (monitor: add del completion for peripheral device)
- 66e56b13 (qdev: add qdev_build_hotpluggable_device_list helper)
cause a QEMU crash when trying to use HMP device_del auto-completion.
It can be easily reproduced by:
<qemu-bin> -enable-kvm ~/images/fedora.qcow2 -monitor stdio -device virtio-net-pci,id=vnet
(qemu) device_del
/home/mapfelba/git/upstream/qemu/hw/core/qdev.c:941:qdev_build_hotpluggable_device_list: Object 0x7f6ce04e4fe0 is not an instance of type device
Aborted (core dumped)
The root cause is qdev_build_hotpluggable_device_list going recursively over
all peripherals and their children assuming all are devices. It doesn't work
since PCI devices have at least on child which is a memory region (bus master).
Solved by observing that all devices appear as direct children of
/machine/peripheral container. No need of going recursively
over all the children.

When running in KVM mode, kvm_set_phys_mem() will silently
fail if registered MemoryRegion address/size is not page
aligned. Causing memory hotplug failure in guest.
Mapping non aligned MemoryRegion in TCG mode 'works', but
sane guest OS still expects page aligned memory module
and fails to initialize it if it's not aligned.
So do not allow non aligned (i.e. valid) address/size

After a reset ESP_TCHI should contain the unique ID
of the chip. This value will be overwritten with the
current tranfer count if the transfer count has
previously been set.
So we should always return the chip id if ESP_TCHI
has never been written to.

We need to support spawning of sysbus devices dynamically via the command line.
The easiest way to represent these dynamically spawned devices in the guest's
memory and IRQ layout is by preallocating some space for dynamic sysbus devices.
This is what the "platform bus" device does. It is a sysbus device that exports
a configurably sized MMIO region and a configurable number of IRQ lines. When
this device encounters sysbus devices that have been dynamically created and not
manually wired up, it dynamically connects them to its own pool of resources.
The machine model can then loop through all of these devices and create a guest
configuration (device tree) to make them visible to the guest.
Signed-off-by: Alexander Graf <agraf@suse.de>
Sysbus devices have a range of MMIO regions they expose. The exact number
of regions is device specific and internal information to the device model.
Expose whether a region exists via a public interface. That way our platform
bus enumeration code can dynamically determine how many regions exist.
Signed-off-by: Alexander Graf <agraf@suse.de>
Sysbus devices can get their IRQ lines connected to other devices. It is
possible to figure out which IRQ line a connection is on and whether a sysbus
device even provides an IRQ connector at a specific offset.
This patch exposes helpers to make this information publicly accessible. We
will need it for the platform bus dynamic sysbus enumeration.
Signed-off-by: Alexander Graf <agraf@suse.de>
Now that we can properly map sysbus devices that haven't been connected to
something forcefully by C code, we can allow the -device command line option
to spawn them.
For machines that don't implement dynamic sysbus assignment in their board
files we add a new bool "has_dynamic_sysbus" to the machine class.
When that property is false (default), we bail out when we see dynamically
spawned sysbus devices, like we did before.
Signed-off-by: Alexander Graf <agraf@suse.de>
Sysbus devices can be spawned by C code or dynamically via the command line.
In the latter case, we need to be able to find the dynamically created devices
to do things with them.
This patch adds a search helper that makes it easy to look for dynamically
spawned sysbus devices.

Such address translation is needed when load address recorded in uImage
is a virtual address. When the actual load address is requested, return
untranslated address: user that needs the translated address can always
apply translation function to it and those that need it untranslated
don't need to do the inverse translation.
Add translation function pointer and its parameter to uimage_load
prototype. Update all existing users.
No user-visible functional changes.

Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.
Change smbios_build_type_1_table() to encode the UUID as specified.
To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

Current support for bus master (clearing OK bit) together with the need to
support guests which do not enable PCI bus mastering, leads to extra state in
VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version
migration for the case when guests use the device before setting DRIVER_OK.
Rip out this code, and replace it:
- Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG
so just drop it for latest machine type.
- For compat machine types, set PCI_COMMAND if DRIVER_OK
is set.
As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h
to a new common header.

Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of
qemu-system-XXXX -M \?
This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:
qemu_register_machine()
type_register()
type_register_internal()
type_table_add()
g_hash_table_insert()
and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):
machine_parse()
object_class_get_list(TYPE_MACHINE)
object_class_foreach()
g_hash_table_foreach()
The current order is a "random" one, for practical purposes, which is
annoying for users.
Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.
The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
order,
- sorts machine types inside the same family in alphabetically decreasing
order,
- sorts standalone machine types between each other in alphabetically
increasing order.
After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.
