pseries: Don't allow duplicate registration of hcalls or RTAS calls

Currently the pseries machine code allows a callback to be registered
for a hypercall number twice, as long as it's the same callback the second
time. We don't test for duplicate registrations of RTAS callbacks at all...

Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

pseries: Fix and cleanup CPU initialization and reset

The current pseries machine init function iterates over the CPUs at several
points, doing various bits of initialization. This is messy; these can
and should be merged into a single iteration doing all the necessary per...

pseries: Implement RTAS system-reboot call

This patch adds the PAPR defined RTAS system-reboot call to the pseries
machine emulation, providing the guest with a way to trigger a reboot.

pseries: Consolidate hack for RTAS display-character usage

Currently the pseries machine contains not one but two somewhat ugly hacks
to allow printing of early debug messages before the guest has properly
read the device tree.

First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually...

qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

pseries: Implement set-time-of-day RTAS function

Currently there is no implementation for set-time-of-day rtas function,
which causes the following warning "setting the clock failed (-1)" on
the guest.

This patch just creates this function, get the timedate diff and store in...

Place pseries vty devices at addresses more similar to existing machines

Currently the qemu pseries machine numbers its virtual serial devices
from 0. However, existing pSeries machines running pHyp number them from
0x30000000.

In theory these indices are arbitrary, since everything necessary for the...

Add SLOF-based partition firmware for pSeries machine, allowing more boot options

Currently, the emulated pSeries machine requires the use of the
-kernel parameter in order to explicitly load a guest kernel. This
means booting from the virtual disk, cdrom or network is not possible....

Implement hcall based RTAS for pSeries machines

On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations. On logical partitions...

Implement assorted pSeries hcalls and RTAS methods

This patch adds several small utility hypercalls and RTAS methods to
the pSeries platform emulation. Specifically:

  • 'display-character' rtas call

This just prints a character to the console, it's occasionally used...
