cd61cb2e2c pc: acpi-build: generate pvpanic device description dynamically
Drops AML template patching and allows to
save some space in SSDT if pvpanic device doesn't
exist by not including disabled device description
into SSDT. It also makes device description
smaller by replacing _STA method with named value
and dropping _INI method.

ebc3028f7a pc: acpi-build: generate _S[345] packages dynamically
Replaces template patching with packages composed
using AML API.

Note on behavior change:
If S3 or S4 is disabled, respective packages won't
be created and put into SSDT. Which saves us some
space in SSDT and doesn't confuse guest OS with
mangled package names as it was done originally.

* factor out ACPI const int packing out of build_append_value()
  and rename build_append_value() to build_append_int_noprefix()
  it will be reused for adding a plain integer value into AML.
  will be used by is aml_processor() and CRS macro helpers
* extend build_append_int{_noprefix}() to support 64-bit values
  it will be used PCI for generating 64bit _CRS entries

a20275fa50 acpi-build: skip hotplugged bridges
hotplugged bridges don't get bsel allocated so acpi hotplug doesn't work
for them anyway.  OTOH adding them in ACPI creates a host of problems,
e.g. they can't be hot-unplugged themselves which is surprising to
users.

So let's just skip these.

afaa2e4bc4 acpi-build: simplify rsdp management for legacy
For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp
for fw cfg. We previously used g_array_free with false parameter,
but this seems to confuse people.
This also wastes a bit of memory as the buffer is unused for new
machine types.

Let's just use plain g_memdup, and free original memory together with
the array.

TODO: rationalize tcpalog memory management, and get rid of the mfre
parameter.

42d859001d acpi-build: fix ACPI RAM management
This fixes multiple issues around ACPI RAM management:

RSDP and linker RAM aren't currently marked dirty
on update, so they won't be migrated correctly.

Let's handle all tables in the same way: set correct size (assert if
too big), update, mark RAM dirty.

This also drops assert checking that table size didn't change: table
size is fundamentally dynamic and depends on hw configuration,
just set the correct size and use that (memory core asserts if size is
too large).

This also means we can drop tracking table size, memory core does this
for us now.

358774d780 pc: acpi-build: migrate RSDP table
Makes sure that RSDP stays the same
/i.e. matches ACPI tables blob in source/
if guest is migrated during RSDP reading or
has been already shadowed by firmware.

Fix applies only to new machine types starting
from 2.3, so it won't break migration for old
machine types.

Linker table is build only once, so if later during
tables rebuild sizes of other ACPI tables change
pointers will be patched incorrectly due to wrong

to find ACPI tables.

d70414a578 acpi: update RSDP on guest access
RSDT offset can change across reboots and that makes
immutable RSDP, which is build at startup, point to
incorrect place in ACPI table blob. That results in
BIOS corrupting tables and guest OS failing to find

We really should have put it in a ROM region, but
we can't change that for old machine types,
let's just set the callback and update it explicitly.

1677f4c66c monitor: Clean up around monitor_handle_fd_param()
monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them.  qerror_report_err() is inappropriate in
many contexts.  monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use.  Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.

Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report().  Turns out that's everywhere.

While there, rename monitor_handle_fd_param2() to monitor_fd_param().

07d01c9c19 smbios: Don't report unknown CPU speed (fix SVVP regression)
SVVP requires processor speed on Type 4 structures to not be unknown.
This was fixed in SeaBIOS 0.5.0 (in 2009), but the bug was reintroduced
in QEMU 2.1.

Revert to old behavior and report CPU speed as 2000 MHz instead of
unknown.

744c6d4747 smbios: Fix dimm size calculation when RAM is multiple of 16GB
The Memory Device size calculation logic is broken when the RAM size is
a multiple of 16GB, making the size of the last entry be 0 instead of
16GB. Fix the logic to handle that case correctly.

13704e4c45 target-i386: Disable HLE and RTM on Haswell & Broadwell
All Haswell CPUs and some Broadwell CPUs were updated by Intel to have
the HLE and RTM features disabled. This will prevent
"-cpu Haswell,enforce" and "-cpu Broadwell,enforce" from running out of
the box on those CPUs.

Disable those features by default on Broadwell and Haswell CPU models,
starting on pc-*-2.3. Users who want to use those features can enable
them explicitly on the command-line.

b4168498f6 multiboot: Fix offset of bootloader name
This fixes a bug introduced in commit 5eba5a66 ('Add bootloader name to
multiboot implementation').

The calculation of the bootloader name offset didn't consider space
occupied by module command lines, so some unlucky module got its command
line partially overwritten with a "qemu" string.

0034a0f239 pc: fix KVM features in pc-1.3 and earlier machine types
Due to a typo, instead of disabling KVM_FEATURE_PV_EOI (bit
6) these machine types are disabling bits 1 and 2, which are
KVM_FEATURE_NOP_IO_DELAY and KVM_FEATURE_MMU_OP.  Not a big deal
because they aren't very important and KVM_FEATURE_MMU_OP is
disabled anyway.  The worst part is actually that KVM_FEATURE_PV_EOI
is remaining enabled.
