      load_elf: replace the address addend by a translation function · 409dbce5
      由 Aurelien Jarno 提交于 
      A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.

This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.

The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

      rom loader: fix sparc -kernel boot. · 3c178e72
      由 Gerd Hoffmann 提交于 
      Changes:
(1) register pstrcpy_targphys() in rom list, it is used for kernel
command lines by a number of architectures.
(2) add rom_ptr() function to get a pointer for applying changes
to loaded images.  Needed for example to tell the linux kernel
where it finds the initrd image by updating the header.
(3) make sparc use rom_ptr for initrd setup.

booting sparc-test works now, and 'info roms' shows this:

(qemu) info roms
addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx"
addr=00000000007ff000 size=0x00000e mem=ram name="cmdline"
addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img"
addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32"

reboot via 'system_reset' works too.

      New qdev_init_nofail() · e23a1b33
      由 Markus Armbruster 提交于 
      Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.

Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling.  I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

      Compile loader only once · ca20cf32
      由 Blue Swirl 提交于 
      Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.

Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.

Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.

      kill drives_table · 751c6a17
      由 Gerd Hoffmann 提交于 
      First step cleaning up the drives handling.  This one does nothing but
removing drives_table[], still it became seriously big.

drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index.  This needs adaption in
*tons* of places all over.

The drives are now maintained as linked list.

      qdev: rework device properties. · ee6847d1
      由 Gerd Hoffmann 提交于 
      This patch is a major overhaul of the device properties.  The properties
are saved directly in the device state struct now, the linked list of
property values is gone.

Advantages:
  * We don't have to maintain the list with the property values.
  * The value in the property list and the value actually used by
    the device can't go out of sync any more (used to happen for
    the pci.devfn == -1 case) because there is only one place where
    the value is stored.
  * A record describing the property is required now, you can't set
    random properties any more.

There are bus-specific and device-specific properties.  The former
should be used for properties common to all bus drivers.  Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.

Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties.  A few common property
types have PropertyInfos defined in qdev-properties.c.  Drivers are free
to implement their own very special property parsers if needed.

Properties can have default values.  If unset they are zero-filled.

      Support addr=... in option argument of -net nic · 5607c388
      由 Markus Armbruster 提交于 
      Make net_client_init() accept addr=, put the value into struct
NICinfo.  Use it in pci_nic_init(), and remove arguments bus and
devfn.

Don't support addr= in third argument of monitor command pci_add,
because that clashes with its first argument.  Admittedly unelegant.

Machines "malta" and "r2d" have a default NIC with a well-known PCI
address.  Deal with that the same way as the NIC model: make
pci_nic_init() take an optional default to be used when the user
doesn't specify one.

      Add common BusState · 02e2da45
      由 Paul Brook 提交于 
      Implement and use a common device bus state.  The main side-effect is
that creating a bus and attaching it to a parent device are no longer
separate operations.  For legacy code we allow a NULL parent, but that
should go away eventually.

Also tweak creation code to veriry theat a device in on the right bus.

      Introduce reset notifier order · 8217606e
      由 Jan Kiszka 提交于 
      Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.
