dc8bc9d657 target/arm: Report KVM's actual PSCI version to guest in dtb
When we're using KVM, the PSCI implementation is provided by the
kernel, but QEMU has to tell the guest about it via the device tree.
Currently we look at the KVM_CAP_ARM_PSCI_0_2 capability to determine
if the kernel is providing at least PSCI 0.2, but if the kernel
provides a newer version than that we will still only tell the guest
it has PSCI 0.2.  (This is fairly harmless; it just means the guest
won't use newer parts of the PSCI API.)

The kernel exposes the specific PSCI version it is implementing via
the ONE_REG API; use this to report in the dtb that the PSCI
implementation is 1.0-compatible if appropriate.  (The device tree
binding currently only distinguishes "pre-0.2", "0.2-compatible" and
"1.0-compatible".)

Support the latest PSCI on TCG and HVF. A 64-bit function called from
AArch32 now returns NOT_SUPPORTED, which is necessary to adhere to SMC
Calling Convention 1.0. It is still not compliant with SMCCC 1.3 since
they do not implement mandatory functions.

d8bdf97972 hw/i2c: flatten pca954x mux device
Previously this device created N subdevices which each owned an i2c bus.
Now this device simply owns the N i2c busses directly.

Tested: Verified devices behind mux are still accessible via qmp and i2c
from within an arm32 SoC.

bad187dfcb hw/input/tsc210x: Don't abort on bad SPI word widths
The tsc210x doesn't support anything other than 16-bit reads on the
SPI bus, but the guest can program the SPI controller to attempt
them anyway. If this happens, don't abort QEMU, just log this as
a guest error.

This fixes our machine_arm_n8x0.py:N8x0Machine.test_n800
acceptance test, which hits this assertion.

The reason we hit the assertion is because the guest kernel thinks
there is a TSC2005 on this SPI bus address, not a TSC210x.  (The n810
*does* have a TSC2005 at this address.) The TSC2005 supports the
24-bit accesses which the guest driver makes, and the TSC210x does
not (that is, our TSC210x emulation is not missing support for a word
width the hardware can handle).  It's not clear whether the problem
here is that the guest kernel incorrectly thinks the n800 has the
same device at this SPI bus address as the n810, or that QEMU's n810
board model doesn't get the SPI devices right.  At this late date
there no longer appears to be any reliable information on the web
about the hardware behaviour, but I am inclined to think this is a
guest kernel bug.  In any case, we prefer not to abort QEMU for
guest-triggerable conditions, so logging the error is the right thing
to do.

cc3b66ac94 mps3-an547: Add missing user ahb interfaces
With these interfaces missing, TFM would delegate peripherals 0, 1,
2, 3 and 8, and qemu would ignore the delegation of interface 8, as
it thought interface 4 was eth & USB.

This patch corrects this behavior and allows TFM to delegate the
eth & USB peripheral to NS mode.

(The old QEMU behaviour was based on revision B of the AN547
appnote; revision C corrects this error in the documentation,
and this commit brings QEMU in to line with how the FPGA
image really behaves.)

1862198702 migration: Remove load_state_old and minimum_version_id_old
There are no longer any VMStateDescription structs in the tree which
use the load_state_old support for custom handling of incoming
migration from very old QEMU.  Remove the mechanism entirely.

This includes removing one stray useless setting of
minimum_version_id_old in a VMStateDescription with no load_state_old
function, which crept in after the global weeding-out of them in
commit 17e3134061.

We can get the job done in spapr_numa_write_assoc_lookup_arrays() a bit
cleaner:

- 'cur_index = int_buf = g_malloc0(..)' is doing a g_malloc0() in the
'int_buf' pointer and making 'cur_index' point to 'int_buf' all in a
single line. No problem with that, but splitting into 2 lines is clearer
to follow

- use g_autofree in 'int_buf' to avoid a g_free() call later on

- 'buf_len' is only being used to store the size of 'int_buf' malloc.
Remove the var and just use the value in g_malloc0() directly

- remove the 'ret' var and just return the result of fdt_setprop()

5f2b96b38e hw/ppc/spapr.c: fail early if no firmware found in machine_init()
The firmware check consists on a file search (qemu_find_file) and load
it via load_imag_targphys(). This validation is not dependent on any
other machine state but it currently being done at the end of
spapr_machine_init(). This means that we can do a lot of stuff and end
up failing at the end for something that we can verify right out of the
gate.

Move this validation to the start of spapr_machine_init() to fail
earlier.  While we're at it, use g_autofree in the 'filename' pointer.

747ffe28ca pnv/xive2: Add support XIVE2 P9-compat mode (or Gen1)
The thread interrupt management area (TIMA) is a set of pages mapped
in the Hypervisor and in the guest OS address space giving access to
the interrupt thread context registers for interrupt management, ACK,
EOI, CPPR, etc.

XIVE2 changes slightly the TIMA layout with extra bits for the new
features, larger CAM lines and the controller provides configuration
switches for backward compatibility. This is called the XIVE2
P9-compat mode, of Gen1 TIMA. It impacts the layout of the TIMA and
the availability of the internal features associated with it,
Automatic Save & Restore for instance. Using a P9 layout also means
setting the controller in such a mode at init time.

As the OPAL driver initializes the XIVE2 controller with a XIVE2/P10
TIMA directly, the XIVE2 model only has a simple support for the
compat mode in the OS TIMA.

707ea7ab4d pnv/xive2: Introduce new capability bits
These bits control the availability of interrupt features : StoreEOI,
PHB PQ_disable, PHB Address-Based Trigger and the overall XIVE
exploitation mode. These bits can be set at early boot time of the
system to activate/deactivate a feature for testing purposes. The
default value should be '1'.

The 'XIVE exploitation mode' bit is a software bit that skiboot could
use to disable the XIVE OS interface and propose a P8 style XICS
interface instead. There are no plans for that for the moment.

c6b8cc370d ppc/pnv: Add support for PQ offload on PHB5
The PQ_disable configuration bit disables the check done on the PQ
state bits when processing new MSI interrupts. When bit 9 is enabled,
the PHB forwards any MSI trigger to the XIVE interrupt controller
without checking the PQ state bits. The XIVE IC knows from the trigger
message that the PQ bits have not been checked and performs the check
locally.

This configuration bit only applies to MSIs and LSIs are still checked
on the PHB to handle the assertion level.

PQ_disable enablement is a requirement for StoreEOI.

The following changes add new accessors to the XiveRouter required to
query and update the PQ state bits. This only applies to the PowerNV
machine. sPAPR accessors are provided but the pSeries machine should
not be concerned by such complex configuration for the moment.

da71b7e3ed ppc/pnv: Add a XIVE2 controller to the POWER10 chip
The XIVE2 interrupt controller of the POWER10 processor follows the
same logic than on POWER9 but the HW interface has been largely
reviewed.  It has a new register interface, different BARs, extra
VSDs, new layout for the XIVE2 structures, and a set of new features
which are described below.

This is a model of the POWER10 XIVE2 interrupt controller for the
PowerNV machine. It focuses primarily on the needs of the skiboot
firmware but some initial hypervisor support is implemented for KVM
use (escalation).

Support for new features will be implemented in time and will require
new support from the OS.

* XIVE2 BARS

The interrupt controller BARs have a different layout outlined below.
Each sub-engine has now own its range and the indirect TIMA access was
replaced with a set of pages, one per CPU, under the IC BAR:

  - IC BAR (Interrupt Controller)
    . 4 pages, one per sub-engine
    . 128 indirect TIMA pages
  - TM BAR (Thread Interrupt Management Area)
    . 4 pages
  - ESB BAR (ESB pages for IPIs)
    . up to 1TB
  - END BAR (ESB pages for ENDs)
    . up to 2TB
  - NVC BAR (Notification Virtual Crowd)
    . up to 128
  - NVPG BAR (Notification Virtual Process and Group)
    . up to 1TB
  - Direct mapped Thread Context Area (reads & writes)

OPAL does not use the grouping and crowd capability.

* Virtual Structure Tables

XIVE2 adds new tables types and also changes the field layout of the END
and NVP Virtualization Structure Descriptors.

  - EAS
  - END new layout
  - NVT was splitted in :
    . NVP (Processor), 32B
    . NVG (Group), 32B
    . NVC (Crowd == P9 block group) 32B
  - IC for remote configuration
  - SYNC for cache injection
  - ERQ for event input queue

The setup is slighly different on XIVE2 because the indexing has changed
for some of the tables, block ID or the chip topology ID can be used.

* XIVE2 features

SCOM and MMIO registers have a new layout and XIVE2 adds a new global
capability and configuration registers.

The lowlevel hardware offers a set of new features among which :

  - a configurable number of priorities : 1 - 8
  - StoreEOI with load-after-store ordering is activated by default
  - Gen2 TIMA layout
  - A P9-compat mode, or Gen1, TIMA toggle bit for SW compatibility
  - increase to 24bit for VP number

Other features will have some impact on the Hypervisor and guest OS
when activated, but this is not required for initial support of the
controller.

09a67f3d0e ppc/xive2: Introduce a presenter matching routine
The VP space is larger in XIVE2 (P10), 24 bits instead of 19bits on
XIVE (P9), and the CAM line can use a 7bits or 8bits thread id.

For now, we only use 7bits thread ids, same as P9, but because of the
change of the size of the VP space, the CAM matching routine is
different between P9 and P10. It is easier to duplicate the whole
routine than to add extra handlers in xive_presenter_tctx_match() used
for P9.

We might come with a better solution later on, after we have added
some more support for the XIVE2 controller.

extra VSDs. These will be described when we add the device model for
the baremetal machine.

The XIVE internal structures for the EAS, END, NVT have different
layouts which is a problem for the current core XIVE framework. To
avoid adding too much complexity in the XIVE models, a new XIVE2 core
framework is introduced. It duplicates the models which are closely
linked to the XIVE internal structures : Xive2Router and
Xive2ENDSource and reuses the XiveSource, XivePresenter, XiveTCTX
models, as they are more generic.

6e7b967503 ppc/pnv: fix default PHB4 QOM hierarchy
Commit 3f4c369ea6 ("ppc/pnv: make PECs create and realize PHB4s")
changed phb4_pec code to create the default PHB4 objects in
pnv_pec_default_phb_realize(). In this process the stacks[] PEC array was
removed and each PHB4 object is tied together with its PEC via the
phb->pec pointer.

This change also broke the previous QOM hierarchy - the PHB4 objects are
being created and not being parented to their respective chips. This can
be verified by 'info pic' in a powernv9 domain with default settings.
pnv_chip_power9_pic_print_info() will fail to find the PHBs because
object_child_foreach_recursive() won't find any.

The solution is to set the parent chip and the parent bus, in the same
way done for user created PHB4 devices, for all PHB4 devices.

5fc983af8b semihosting/arm-compat: replace heuristic for softmmu SYS_HEAPINFO
The previous numbers were a guess at best and rather arbitrary without
taking into account anything that might be loaded. Instead of using
guesses based on the state of registers implement a new function that:

 a) scans the MemoryRegions for the largest RAM block
 b) iterates through all "ROM" blobs looking for the biggest gap

The "ROM" blobs include all code loaded via -kernel and the various
-device loader techniques.

2beb1e5f9a rtc: Have event RTC_CHANGE identify the RTC by QOM path
Event RTC_CHANGE is "emitted when the guest changes the RTC time" (and
the RTC supports the event).  What if there's more than one RTC?
Which one changed?  New @qom-path identifies it.
