Starting Qemu with "qemu-system-tricore -nographic -M tricore_testboard -S"

This happens because tricore_cpu_get_phys_page_debug() is not implemented
yet, this is a temporary workaround to avoid the crash.

According to the PoP channel command words (CCW) must be doubleword
aligned and 31 bit addressable for format 1 and 24 bit addressable for
format 0 CCWs.
If the channel subsystem encounters a ccw address which does not satisfy
this alignment requirement a program-check condition is recognised.
The situation with 31 bit addressable is a bit more complicated: both the
ORB and a format 1 CCW TIC hold the address of (the rest of) the channel
program, that is the address of the next CCW in a word, and the PoP
mandates that bit 0 of that word shall be zero -- or a program-check
condition is to be recognized -- and does not belong to the field holding
the ccw address.
Since in code the corresponding fields span across the whole word (unlike
in PoP where these are defined as 31 bit wide) we can check this by
applying a mask. The 24 addressable case isn't affecting TIC because the
address is composed of a halfword and a byte portion (no additional zero
bit requirements) and just slightly complicates the ORB case where also
bits 1-7 need to be zero.
The same requirements (especially n-bit addressability) apply to the
ccw addresses generated while chaining.
Let's make our CSS implementation follow the AR more closely.

The processing of the scancodes for PAUSE/BREAK has been broken since

Author: Hervé Poussineau <hpoussin@reactos.org>
Date: Thu Sep 15 22:06:26 2016 +0200
ps2: use QEMU qcodes instead of scancodes
When using a VNC client, with the raw scancode extension, the client
will send a scancode of 0xc6 for both PAUSE and BREAK. There is mistakenly
no entry in the qcode_to_number table for this scancode, so
ps2_keyboard_event() just generates a log message and discards the
scancode
When using a SPICE client, it will also send 0xc6 for BREAK, but
will send 0xe1 0x1d 0x45 0xe1 0x9d 0xc5 for PAUSE. There is no
entry in the qcode_to_number table for the scancode 0xe1 because
it is a special XT keyboard prefix not mapping to any QKeyCode.
Again ps2_keyboard_event() just generates a log message and discards
the scancode. The following 0x1d, 0x45, 0x9d, 0xc5 scancodes get
handled correctly. Rather than trying to handle 3 byte sequences
of scancodes in the PS/2 driver, special case the SPICE input
code so that it captures the 3 byte pause sequence and turns it
into a Pause QKeyCode.

target/i386: Don't use x86_cpu_load_def() on "max" CPU model
target/i386: Define CPUID_MODEL_ID_SZ macro
target/i386: Use host_vendor_fms() in max_x86_cpu_initfn()
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When commit 0bacd8b304 ('i386: Don't set CPUClass::cpu_def on
"max" model') removed the CPUClass::cpu_def field, we kept using
the x86_cpu_load_def() helper directly in max_x86_cpu_initfn(),
emulating the previous behavior when CPUClass::cpu_def was set.
However, x86_cpu_load_def() is intended to help initialization of
CPU models from the builtin_x86_defs table, and does lots of
other steps that are not necessary for "max".
One of the things x86_cpu_load_def() do is to set the properties
listed at tcg_default_props/kvm_default_props. We must not do
that on the "max" CPU model, otherwise under KVM we will
incorrectly report all KVM features as always available, and the
"svm" feature as always unavailable. The latter caused the bug
reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=1467599
("Unable to start domain: the CPU is incompatible with host CPU:
Host CPU does not provide required features: svm")
Replace x86_cpu_load_def() with simple object_property_set*()
calls. In addition to fixing the above bug, this makes the KVM
branch in max_x86_cpu_initfn() very similar to the existing TCG
branch.
For reference, the full list of steps performed by
x86_cpu_load_def() is:
* Setting min-level and min-xlevel. Already done by
max_x86_cpu_initfn().
* Setting family/model/stepping/model-id. Done by the code added
to max_x86_cpu_initfn() in this patch.
* Copying def->features. Wrong because "-cpu max" features need to
be calculated at realize time. This was not a problem in the
current code because host_cpudef.features was all zeroes.
* x86_cpu_apply_props() calls. This causes the bug above, and
shouldn't be done.
* Setting CPUID_EXT_HYPERVISOR. Not needed because it is already
reported by x86_cpu_get_supported_feature_word(), and because
"-cpu max" features need to be calculated at realize time.
* Setting CPU vendor to host CPU vendor if on KVM mode.
Redundant, because max_x86_cpu_initfn() already sets it to the
host CPU vendor.

The sm501 device uses vmstate_register_ram_global() to register its
memory region for migration. This means it gets a name that is
assumed to be global to the whole system, which in turn means that if
you create two of the device we assert because of the duplication:
qemu-system-ppc -device sm501 -device sm501
RAMBlock "sm501.local" already registered, abort!
Aborted (core dumped)
Changing this to just use memory_region_init_ram()'s automatic
registration of the memory region with a device-local name fixes
this. The downside is that it breaks migration compatibility, but
luckily we only added migration support to this device in the 2.10
release cycle so we haven't released a QEMU version with the broken
implementation.

There are a handful of bugfixes here plus an update for the "pseries"
guest firmware (SLOF).
This is later than ideal for a guest firmware update. However, this
does include a number of fixes in that guest firmware, so I think it's
worth the risk of squeezing this in just before the hard freeze.

When initiating a program check interruption by calling program_interrupt
the instruction length (ilen) of the current instruction is supplied as
the third parameter.
On s390x all the IO instructions are of instruction format S and their
ilen is 4. The calls to program_interrupt (introduced by commits
7b18aad543 ("s390: Add channel I/O instructions.", 2013-01-24) and
61bf0dcb2e ("s390x/ioinst: Add missing alignment checks for IO
instructions", 2013-06-21)) however use ilen == 2.
This is probably due to a confusion between ilen which specifies the
instruction length in bytes and ILC which does the same but in halfwords.
If kvm_enabled() this does not actually matter, because the ilen
parameter of program_interrupt is effectively unused.
Let's provide the correct ilen to program_interrupt.

These functions can not be compiled with --disable-tcg. But since we
need the other functions from helper.c in the non-tcg build, we can also
not simply remove helper.c from the non-tcg builds. Thus the problematic
functions have to be moved into a separate new file instead that we
can later omit in the non-tcg builds.

misc_helper.c won't be compiled with --disable-tcg anymore, but we
still need the program_interrupt() function in that case. Move it
to interrupt.c instead, and refactor it to re-use the code from
trigger_pgm_exception() (for TCG) and enter_pgmcheck() (for KVM,
which now got renamed to kvm_s390_program_interrupt() for
clarity).
