I recently noticed that test-obj-y contains a file called
tests/check-block-qtest.o which simply does not belong to any .c
file and thus wondered why this is not causing any trouble. It is
only used to add -Itests to the command line (which refers to the
build directory). However, it is not needed because "-iquote $(@D)"
already sets this up in rules.mak. Thus we can simply remove this
variable.

test-qapi.py doesn't force a specific encoding for stderr or
stdout, but the reference files used by check-qapi-schema are in
UTF-8. This breaks check-qapi-schema under certain circumstances
(e.g. if using the C locale and Python < 3.7).
We need to make sure test-qapi.py always generate UTF-8 output
somehow. On Python 3.7+ we can do it using
`sys.stdout.reconfigure(...)`, but we need a solution that works
with older Python versions.
Instead of trying a hack like reopening sys.stdout and
sys.stderr, we can just tell Python to use UTF-8 for I/O encoding
when running test-qapi.py. Do it by setting PYTHONIOENCODING.

This requires some changes to keep iotests 104 and 207 working.
qemu-img info in 104 will now return a filename including the user name
and the port, which need to be filtered by adjusting REMOTE_TEST_DIR in
common.rc. This additional information has to be marked optional,
however (which is simple as REMOTE_TEST_DIR is a regex), because
otherwise 197 and 215 would fail: They use it (indirectly) to filter
qemu-img create output which contains a backing filename they have
passed to it -- which probably does not contain a user name or port
number.
The problem in 207 is a nice one to have: qemu-img info used to return
json:{} filenames, but with this patch it returns nice plain ones. We
now need to adjust the filtering to hide the user name (and port number
while we are at it). The simplest way to do this is to include both in
iotests.remote_filename() so that bdrv_refresh_filename() will not
change it, and then iotests.img_info_log() will filter it correctly
automatically.

In the M-profile architecture, if the CPU implements the DSP extension
then the XPSR has GE bits, in the same way as the A-profile CPSR. When
we added DSP extension support we forgot to add support for reading
and writing the GE bits, which are stored in env->GE. We did put in
the code to add XPSR_GE to the mask of bits to update in the v7m_msr
helper, but forgot it in v7m_mrs. We also must not allow the XPSR we
pull off the stack on exception return to set the nonexistent GE bits.
Correct these errors:
* read and write env->GE in xpsr_read() and xpsr_write()
* only set GE bits on exception return if DSP present
* read GE bits for MRS if DSP present

At the moment the Arm implementations of kvm_arch_{get,put}_registers()
don't support having QEMU change the values of system registers
(aka coprocessor registers for AArch32). This is because although
kvm_arch_get_registers() calls write_list_to_cpustate() to
update the CPU state struct fields (so QEMU code can read the
values in the usual way), kvm_arch_put_registers() does not
call write_cpustate_to_list(), meaning that any changes to
the CPU state struct fields will not be passed back to KVM.
The rationale for this design is documented in a comment in the
AArch32 kvm_arch_put_registers() -- writing the values in the
cpregs list into the CPU state struct is "lossy" because the
write of a register might not succeed, and so if we blindly
copy the CPU state values back again we will incorrectly
change register values for the guest. The assumption was that
no QEMU code would need to write to the registers.
However, when we implemented debug support for KVM guests, we
broke that assumption: the code to handle "set the guest up
to take a breakpoint exception" does so by updating various
guest registers including ESR_EL1.
Support this by making kvm_arch_put_registers() synchronize
CPU state back into the list. We sync only those registers
where the initial write succeeds, which should be sufficient.
This commit is the same as commit 823e1b3818 which we
had to revert in commit 942f99c825, except that the bug
which was preventing EDK2 guest firmware running has been fixed:
kvm_arm_reset_vcpu() now calls write_list_to_cpustate().

The Raspberry Pi boards have a physical memory map which does
not allow for more than 1GB of RAM. Currently if the user tries
to ask for more then we fail in a confusing way:
$ qemu-system-aarch64 --machine raspi3 -m 8G
Unexpected error in visit_type_uintN() at qapi/qapi-visit-core.c:164:
qemu-system-aarch64: Parameter 'vcram-base' expects uint32_t
Aborted (core dumped)
Catch this earlier and diagnose it with a more friendly message:
$ qemu-system-aarch64 --machine raspi3 -m 8G
qemu-system-aarch64: Requested ram size is too large for this machine: maximum is 1GB

The ARM virt machines put firmware in flash memory. To configure it,
you use -drive if=pflash,unit=0,... and optionally -drive
if=pflash,unit=1,...
Why two -drive? This permits setting up one part of the flash memory
read-only, and the other part read/write. It also makes upgrading
firmware on the host easier. Below the hood, we get two separate
flash devices, because we were too lazy to improve our flash device
models to support sector protection.
The problem at hand is to do the same with -blockdev somehow, as one
more step towards deprecating -drive.
We recently solved this problem for x86 PC machines, in commit
ebc29e1bea. See the commit message for design rationale.
This commit solves it for ARM virt basically the same way: new machine
properties pflash0, pflash1 forward to the onboard flash devices'
properties. Requires creating the onboard devices in the
.instance_init() method virt_instance_init(). The existing code to
pick up drives defined with -drive if=pflash is replaced by code to
desugar into the machine properties.
There are a few behavioral differences, though:
* The flash devices are always present (x86: only present if
configured)
* Flash base addresses and sizes are fixed (x86: sizes depend on
images, mapped back to back below a fixed address)
* -bios configures contents of first pflash (x86: -bios configures ROM
contents)
* -bios is rejected when first pflash is also configured with -machine
pflash0=... (x86: bios is silently ignored then)
* -machine pflash1=... does not require -machine pflash0=... (x86: it
does).
The actual code is a bit simpler than for x86 mostly due to the first
two differences.
Before the patch, all the action is in create_flash(), called from the
machine's .init() method machvirt_init():
main()
machine_run_board_init()
machvirt_init()
create_flash()
create_one_flash() for flash[0]
create
configure
includes obeying -drive if=pflash,unit=0
realize
map
fall back to -bios
create_one_flash() for flash[1]
create
configure
includes obeying -drive if=pflash,unit=1
realize
map
update FDT
To make the machine properties work, we need to move device creation
to its .instance_init() method virt_instance_init().
Another complication is machvirt_init()'s computation of
@firmware_loaded: it predicts what create_flash() will do. Instead of
predicting what create_flash()'s replacement virt_firmware_init() will
do, I decided to have virt_firmware_init() return what it did.
Requires calling it a bit earlier.
Resulting call tree:
main()
current_machine = object_new()
...
virt_instance_init()
virt_flash_create()
virt_flash_create1() for flash[0]
create
configure: set defaults
become child of machine [NEW]
add machine prop pflash0 as alias for drive [NEW]
virt_flash_create1() for flash[1]
create
configure: set defaults
become child of machine [NEW]

for all machine props from the command line: machine_set_property()
...
property_set_alias() for machine props pflash0, pflash1
...
set_drive() for cfi.pflash01 prop drive
this is how -machine pflash0=... etc set
machine_run_board_init(current_machine);

The loop does two things: map legacy -drive to properties, and collect
all the backends for use after the loop. The next patch will factor
out the former for reuse in hw/arm/virt.c. To make that easier,
rearrange the loop so it does the first thing first, and the second
thing second.

Fix the check preventing calling pixman functions that would access
memory outside allocated vram. The r128 X driver sometimes seem to try
blits that span outside vram, this check prevents crashing QEMU in
that case. (The r128 X driver may have problems even on real hardware
so I'm not sure if it's a client bug or emulation problem but at least
QEMU should survive.)

The SPICE_RING_PROD_ITEM() macro is initializing a local
'uint64_t *' variable to point to the 'el' field inside
the QXLReleaseRing struct. This uint64_t field is not
guaranteed aligned as the struct is packed.
Code should not take the address of fields within a
packed struct. Changing the SPICE_RING_PROD_ITEM()
macro to avoid taking the address of the field is
impractical. It is clearer to just remove the macro
and inline its functionality in the three call sites
that need it.
