qbus_find() adds an informational line to error messages, and prints
both lines with one qemu_error(). Use error_printf() for the
informational line instead.
While there, simplify: instead of printing buffers filled by
qbus_list_bus() and qbus_list_dev() in one go, make them print it.
qdev_device_help() prints device information with qemu_error(). A
later commit will make qemu_error() print additional stuff that is
only appropriate for proper errors, and then this will break. Use
error_printf() instead.
While there, simplify: instead of printing a buffer filled by
qdev_print_devinfo() in one go, make qdev_print_devinfo() print it.
The old test assumes that "hotplugged" implies "we have a current
monitor for reading the key". This is in fact true, but it's not
obviously true.
Aside: if it were false, we could pass a null pointer to
monitor_read_bdrv_key_start(), which would then crash.
The previous commit permits us to check for "we have a current
monitor" directly, so do that.
Code duplicated in commit 0ecdffbb. The two versions are similar, but
not identical:
* cmos_init() reports errors to stderr, pc_boot_set() via
qemu_error(). The latter is fine for both, so pick that for the
common code.
* cmos_init() obeys fd_bootchk, pc_boot_set() ignores it. Make it a
parameter of the common code.
Commit 0ecdffbb created pc_boot_set() for use from monitor command
"boot_set", via qemu_boot_set(). pc_boot_set() reports errors to
cur_mon, which works fine for monitor code.
Commit e0f084bf reused the function int reset handler
restore_boot_devices(). Use of cur_mon is problematic in that
context. For instance, the "Too many boot devices for PC" error for
"-boot order=abcdefgh,once=c" goes to the monitor instead of stderr.
The monitor may not even exist.
Fix by switching to qemu_error().
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.

This grand cleanup drops all reset and vmsave/load related
synchronization points in favor of four(!) generic hooks:
- cpu_synchronize_all_states in qemu_savevm_state_complete
(initial sync from kernel before vmsave)
- cpu_synchronize_all_post_init in qemu_loadvm_state
(writeback after vmload)
- cpu_synchronize_all_post_init in main after machine init
- cpu_synchronize_all_post_reset in qemu_system_reset
(writeback after system reset)
These writeback points + the existing one of VCPU exec after
cpu_synchronize_state map on three levels of writeback:
- KVM_PUT_RUNTIME_STATE (during runtime, other VCPUs continue to run)
- KVM_PUT_RESET_STATE (on synchronous system reset, all VCPUs stopped)
- KVM_PUT_FULL_STATE (on init or vmload, all VCPUs stopped as well)
This level is passed to the arch-specific VCPU state writing function
that will decide which concrete substates need to be written. That way,
no writer of load, save or reset functions that interact with in-kernel
KVM states will ever have to worry about synchronization again. That
also means that a lot of reasons for races, segfaults and deadlocks are
eliminated.
cpu_synchronize_state remains untouched, just as Anthony suggested. We
continue to need it before reading or writing of VCPU states that are
also tracked by in-kernel KVM subsystems.
Consequently, this patch removes many cpu_synchronize_state calls that
are now redundant, just like remaining explicit register syncs.

Our guest systems need to know by how much the timebase increases every second,
so there usually is a "timebase-frequency" property in the cpu leaf of the
device tree.
This property is missing in OpenBIOS.
With qemu, Linux's fallback timebase speed and qemu's internal timebase speed
match up. With KVM, that is no longer true. The guest is running at the same
timebase speed as the host.
This leads to massive timing problems. On my test machine, a "sleep 2" takes
about 14 seconds with KVM enabled.
This patch exports the timebase frequency to OpenBIOS, so it can then put them
into the device tree.

The interrupt code as is didn't really work for me. I couldn't even convince

So let's do this right. Let's map all PCI interrupts to 0x1b - 0x1e. That way
we're at least a small step closer to what real hardware does.
I also took the interrupt pin to line conversion from OpenBIOS, which at least
assures us we're compatible with our firmware :-).
