Introduce the following build scripts under "tests/uefi-test-tools":
* "build.sh" builds a single module (a UEFI application) from
UefiTestToolsPkg, for a single QEMU emulation target.
"build.sh" relies on cross-compilers when the emulation target and the
build host architecture don't match. The cross-compiler prefix is
computed according to a fixed, Linux-specific pattern. No attempt is
made to copy or reimplement the GNU Make magic from "qemu/roms/Makefile"
for cross-compiler prefix determination. The reason is that the build
host OSes that are officially supported by edk2, and those that are
supported by QEMU, intersect only in Linux. (Note that the UNIXGCC
toolchain is being removed from edk2,
<https://bugzilla.tianocore.org/show_bug.cgi?id=1377>.)
* "Makefile" currently builds the "UefiTestToolsPkg/BiosTablesTest"
application, for arm, aarch64, i386, and x86_64, with the help of
"build.sh".
"Makefile" turns each resultant UEFI executable into a UEFI-bootable,
qcow2-compressed ISO image. The ISO images are output as
"tests/data/uefi-boot-images/bios-tables-test.<TARGET>.iso.qcow2".
Each ISO image should be passed to QEMU as follows:
-drive id=boot-cd,if=none,readonly,format=qcow2,file=$ISO \
-device virtio-scsi-pci,id=scsi0 \
-device scsi-cd,drive=boot-cd,bus=scsi0.0,bootindex=0 \
"Makefile" assumes that "mkdosfs", "mtools", and "genisoimage" are
present.

The "bios-tables-test" program in QEMU's test suite locates the RSD PTR
ACPI table in guest RAM, and (chasing pointers to other ACPI tables)
performs various sanity checks on the QEMU-generated and
firmware-installed tables.
Currently this set of test cases doesn't work with UEFI guests. The ACPI
spec defines distinct methods for OSPM to locate the RSD PTR on
traditional BIOS vs. UEFI platforms, and the UEFI method is more difficult
to implement from the hypervisor side with just raw guest memory access.
Add a UEFI application (to be booted in the UEFI guest) that populates a
small, MB-aligned structure in guest RAM. The structure begins with a
signature GUID. The hypervisor should loop over all MB-aligned pages in
guest RAM until one matches the signature GUID at offset 0, at which point
the hypervisor can fetch the RSDP address field(s) from the structure.
QEMU's test logic currently spins on a pre-determined guest address, until
that address assumes a magic value. The method described in this patch is
conceptually the same ("busy loop until match is found"), except there is
no hard-coded address. This plays a lot more nicely with UEFI guest
firmware (we'll be able to use the normal page allocation UEFI service).
Given the size of EFI_GUID (16 bytes -- 128 bits), mismatches should be
astronomically unlikely. In addition, given the typical guest RAM size for
such tests (128 MB), there are 128 locations to check in one iteration of
the "outer" loop, which shouldn't introduce an intolerable delay after the
guest stores the RSDP address(es), and then the GUID.
The GUID that the hypervisor should search for is
AB87A6B1-2034-BDA0-71BD-375007757785
Expressed as a byte array:
{
0xb1, 0xa6, 0x87, 0xab,
0x34, 0x20,
0xa0, 0xbd,
0x71, 0xbd, 0x37, 0x50, 0x07, 0x75, 0x77, 0x85
}
Note that in the patch, we define "gBiosTablesTestGuid" with all bits
inverted. This is a simple method to prevent the UEFI binary, which
incorporates "gBiosTablesTestGuid", from matching the actual GUID in guest
RAM.
The UEFI application is written against the edk2 framework, which was
introduced earlier as a git submodule. The next patch will provide build
scripts for maintainers.
The source code follows the edk2 coding style, and is licensed under the
2-clause BSDL (in case someone would like to include UefiTestToolsPkg
content in a different edk2 platform).
The "UefiTestToolsPkg.dsc" platform description file resolves the used
edk2 library classes to instances (= library implementations) such that
the UEFI binaries inherit no platform dependencies. They are expected to
run on any system that conforms to the UEFI-2.3.1 spec (which was released
in 2012). The arch-specific build options are carried over from edk2's
ArmVirtPkg and OvmfPkg platforms.

The roms/edk2 submodule can help with three goals:
- build the OVMF and ArmVirtQemu virtual UEFI firmware platforms (to be
implemented later),
- build the EfiRom tool on the fly, which is used in roms/Makefile, for
building the "efirom" target,
- build UEFI test applications (to be run in guests), for qtest support.
Edk2 commit 85588389222a3636baf0f9ed8227f2434af4c3f9 stands for the latest
"stable tag", namely "edk2-stable201811".

QEMU's top-level "make clean"; exempt the full pathnames from the "find"

several time qemu_opts_set() will ignore all but the first option
list. Since the spice server is a singleton, it makes sense to merge
all the options, the last value being the one taken into account.
This changes the behaviour from, for ex:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5900
to:
$ qemu... -spice port=5900 -spice port=5901 -> port: 5901

It's easy to avoid that situation since qemu spice_display_is_running
tracks the server state.
After the commit "spice: do not stop spice if VM is paused", it will
be possible to pause and resume the VM, and this will call
qemu_spice_display_start() twice. The easiest is to add a check for
spice_display_is_running with this patch to avoid the assert.

Most chardev backend handle write() as discarded data if underlying
system is disconnected. For unknown historical reasons, the Spice
backend has "reliable" write: it will wait until the client end is
reconnected to do further successful write().
To decide whether it make sense to wait until the client is
reconnected (or queue the writes), let's review Spice chardev usage
and handling of a disconnected client:
* spice vdagent
The agents reopen the virtio port on disconnect. In qemu side,
virtio_serial_close() will also discard pending data.
* usb redirection
A disconnect creates a device disconnection.
* smartcard emulation
Data is discarded in passthru_apdu_from_guest().
(Spice doesn't explicitly open the smartcard char device until
upcoming 0.14.2, commit 69a5cfc74131ec0459f2eb5a231139f5a69a8037)
* spice webdavd
The daemon will restart the service, and reopen the virtio port.
* spice ports (serial console, qemu monitor..)
Depends on the associated device or usage.
- serial, may be throttled or discarded on write, depending on
device
- QMP/HMP monitor have some CLOSED event handling, but want to
flush the write, which will finish when a new client connects.
On disconnect/reconnect, the client starts with fresh sessions. If it
is a seamless migration, the client disconnects after the source
migrated. The handling of source disconnect in qemu is thus irrelevant
for the Spice session migration.
For all these use cases, it is better to discard writes when the
client is disconnected, and require the vm-side device/agent to behave
correctly on CHR_EVENT_CLOSED, to stop reading and writing from
the spice chardev.

The license information in this file is very messy. A short note at
the beginning says GPL first, but the long boilerplate code then
talks about "GNU Lesser General Public License version 2.0". First,
there is no such version of the "GNU Lesser GPL", it only started with
version 2.1. In version 2.0, it was still called "GNU Library GPL"
instead. Second, you can easily get the license of this file wrong
if you only quickly glance at the long boilerplate code.
Anyway, looking at the text of the LGPL (see COPYING.LIB in the top
directory), the license clearly states in section "3." that one should
rather replace the license information with the GPL information in
such a case of a mixture instead. Thus let's clean up the confusing

When bitmaps are persistent, they may incur a disk read or write when bitmaps
are added or removed. For configurations like virtio-dataplane, failing to
acquire this lock will abort QEMU when disk IO occurs.
We used to acquire aio_context as part of the bitmap lookup, so re-introduce
the lock for just the cases that have an IO penalty. Commit 2119882c removed
these locks, and I failed to notice this when we committed fd5ae4cc, so this
has been broken since persistent bitmaps were introduced.

The meaning of the states has changed subtly over time,
this should bring the understanding more in-line with the
current, actual usages.

Since qemu currently doesn't flush persistent bitmaps to disk until
shutdown (which might be MUCH later), it's useful if 'query-block'
at least shows WHICH bitmaps will (eventually) make it to persistent
storage. Update affected iotests.

FLIX adds branch and loop instruction variants with 15- and 18-bit wide
target offset. Implement them as additional names for the ordinary
branch/loop opcodes.

There are opcodes that differ only in encoding or possible range of
immediate arguments. Allow multiple names for single opcode translation
table entry to reduce code duplication in that case.
Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
Requirement for alphabetical opcode sorting in opcode tables is awkward
and does not allow sharing implementation between multiple opcodes.
Use hash tables to find opcodes by name. Move implementation from the
translate.c to the helper.c to its only user and remove declaration from
the cpu.h

Don't run xtensa_finalize_config at the time of core registration,

xtensa-modules part of the test_mmuhifi_c3 core is missing fixes that
returns XTENSA_UNDEFINED for undefined opcodes and marks all data
structures static. Run sed script from target/xtensa/import_core.sh on
it. This fixes test_sr tests for missing special registers.

A few targets don't emit RTC_CHANGE, we could restrict the event to
the tagets that do emit it.
Note: There is a lot more of events & commands that we could restrict
to capable targets, with the cost of some additional complexity, but
the benefit of added correctness and better introspection.
