Peter Maydell 2c023d3675 target/arm: Use correct entrypoint for SVC taken from Hyp to Hyp
The exception caused by an SVC instruction may be taken to AArch32
Hyp mode for two reasons:
 * HCR.TGE indicates that exceptions from EL0 should trap to EL2
 * we were already in Hyp mode

The entrypoint in the vector table to be used differs in these two
cases: for an exception routed to Hyp mode from EL0, we enter at the
common 0x14 "hyp trap" entrypoint.  For SVC from Hyp mode to Hyp
mode, we enter at the 0x08 (svc/hvc trap) entrypoint.
In the v8A Arm ARM pseudocode this is done in AArch32.TakeSVCException.

QEMU incorrectly routed both of these exceptions to the 0x14
entrypoint.  Correct the entrypoint for SVC from Hyp to Hyp by making
use of the existing logic which handles "normal entrypoint for
Hyp-to-Hyp, otherwise 0x14" for traps like UNDEF and data/prefetch
aborts (reproduced here since it's outside the visible context
in the diff for this commit):

    if (arm_current_el(env) != 2 && addr < 0x14) {
        addr = 0x14;
    }

Peter Maydell 961b4912c1 hw/intc/arm_gicv3_its: Implement MOVI
Implement the ITS MOVI command. This command specifies a (physical) LPI
by DeviceID and EventID and provides a new ICID for it. The ITS must
find the interrupt translation table entry for the LPI, which will
tell it the old ICID. It then moves the pending state of the LPI from
the old redistributor to the new one and updates the ICID field in
the translation table entry.

This is another GICv3 ITS command that we forgot to implement.  Linux
does use this one, but only if the guest powers off one of its CPUs.

Peter Maydell 8b8bb0146b hw/intc/arm_gicv3_its: Check table bounds against correct limit
Currently when we fill in a TableDesc based on the value the guest
has written to the GITS_BASER<n> register, we calculate both:
 * num_entries : the number of entries in the table, constrained
   by the amount of memory the guest has given it
 * num_ids : the number of IDs we support for this table,
   constrained by the implementation choices and the architecture
   (eg DeviceIDs are 16 bits, so num_ids is 1 << 16)

When validating ITS commands, however, we check only num_ids,
thus allowing a broken guest to specify table entries that
index off the end of it. This will only corrupt guest memory,
but the ITS is supposed to reject such commands as invalid.

Instead of calculating both num_entries and num_ids, set
num_entries to the minimum of the two limits, and check that.

Peter Maydell 0ffe88e691 hw/intc/arm_gicv3_its: Make GITS_BASER<n> RAZ/WI for unimplemented registers
The ITS has a bank of 8 GITS_BASER<n> registers, which allow the
guest to specify the base address of various data tables.  Each
register has a read-only type field indicating which table it is for
and a read-write field where the guest can write in the base address
(among other things).  We currently allow the guest to write the
writeable fields for all eight registers, even if the type field is 0
indicating "Unimplemented".  This means the guest can provoke QEMU
into asserting by writing an address into one of these unimplemented
base registers, which bypasses the "if (!value) continue" check in
extract_table_params() and lets us hit the assertion that the type
field is one of the permitted table types.

Prevent the assertion by not allowing the guest to write to the
unimplemented base registers. This means their value will remain 0
and extract_table_params() will ignore them.

Peter Maydell 7e062b98a2 hw/intc/arm_gicv3_its: Provide read accessor for translation_ops
The MemoryRegionOps gicv3_its_translation_ops currently provides only
a .write_with_attrs function, because the only register in this
region is the write-only GITS_TRANSLATER.  However, if you don't
provide a read function and the guest tries reading from this memory
region, QEMU will crash because
memory_region_read_with_attrs_accessor() calls a NULL pointer.

Add a read function which always returns 0, to cover both bogus
attempts to read GITS_TRANSLATER and also reads from the rest of the
region, which is documented to be reserved, RES0.

Peter Maydell d7d19c0aeb hw/intc/arm_gicv3_redist: Remove unnecessary zero checks
The ITS-related parts of the redistributor code make some checks for
whether registers like GICR_PROPBASER and GICR_PENDBASER are zero.
There is no requirement in the specification for treating zeroes in
these address registers specially -- they contain guest physical
addresses and it is entirely valid (if unusual) for the guest to
choose to put the tables they address at guest physical address zero.
We use these values only to calculate guest addresses, and attempts
by the guest to use a bad address will be handled by the
address_space_* functions which we use to do the loads and stores.

Remove the unnecessary checks.

this causes GITS_CREADR to be cleared.  However it does not have an
equivalent clause for GITS_CWRITER.  (This is because GITS_CREADR is

it.) Remove the code that clears GITS_CWRITER on GITS_CBASER writes.

Peter Maydell e5ff041f62 hw/intc/arm_gicv3: Initialise dma_as in GIC, not ITS
In our implementation, all ITSes connected to a GIC share a single
AddressSpace, which we keep in the GICv3State::dma_as field and
initialized based on the GIC's 'sysmem' property. The right place
to set it up by calling address_space_init() is therefore in the
GIC's realize method, not the ITS's realize.

This fixes a theoretical bug where QEMU hangs on startup if the board
model creates two ITSes connected to the same GIC -- we would call
address_space_init() twice on the same AddressSpace*, which creates
an infinite loop in the QTAILQ that softmmu/memory.c uses to store
its list of AddressSpaces and causes any subsequent attempt to
iterate through that list to loop forever.  There aren't any board
models like that in the tree at the moment, though.

Francisco Iglesias 00f05c02f9 hw/dma/xlnx_csu_dma: Support starting a read transfer through a class method
An option on real hardware when embedding a DMA engine into a peripheral
is to make the peripheral control the engine through a custom DMA control
(hardware) interface between the two. Software drivers in this scenario
configure and trigger DMA operations through the controlling peripheral's
register API (for example, writing a specific bit in a register could
propagate down to a transfer start signal on the DMA control interface).
At the same time the status, results and interrupts for the transfer might
still be intended to be read and caught through the DMA engine's register
API (and signals).

This patch adds a class 'read' method for allowing to start read transfers
from peripherals embedding and controlling the Xilinx CSU DMA engine as in
above scenario.

Peter Maydell 2f93d8b04a rtc: Move RTC function prototypes to their own header
softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff().  Currently we keep the prototypes for these in
qemu-common.h, but most files don't need them.  Move them to their
own header, a new include/sysemu/rtc.h.

Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.

The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

Peter Maydell 617dff091f hw/char/exynos4210_uart: Fix crash on trying to load VM state
The exynos4210_uart_post_load() function assumes that it is passed
the Exynos4210UartState, but it has been attached to the
VMStateDescription for the Exynos4210UartFIFO type.  The result is a
SIGSEGV when attempting to load VM state for any machine type
including this device.

Fix the bug by attaching the post-load function to the VMSD for the
Exynos4210UartState.  This is the logical place for it, because the
actions it does relate to the entire UART state, not just the FIFO.

Thanks to the bug reporter @TrungNguyen1909 for the clear bug
description and the suggested fix.

"meson test" can be asked to run tests verbosely; this makes it usable
also for qemu-iotests's own harness, and it lets "make check-block"
reuse mtest2make.py's infrastructure to find and build test dependencies.

Adjust check-block.sh to use the standard exit code that reports a test
as skipped.  Alternatively, in the future we could make it produce TAP
output, which is consistent with all other "make check" tests.

Ross Lagerwall a021a2dd8b xen-mapcache: Avoid entry->lock overflow
In some cases, a particular mapcache entry may be mapped 256 times
causing the lock field to wrap to 0. For example, this may happen when
using emulated NVME and the guest submits a large scatter-gather write.
At this point, the entry map be remapped causing QEMU to write the wrong
data or crash (since remap is not atomic).

Avoid this overflow by increasing the lock field to a uint32_t and also
detect it and abort rather than continuing regardless.

Jason Andryuk 9288e803e6 xen-hvm: Allow disabling buffer_io_timer
commit f37f29d314 "xen: slightly simplify bufioreq handling" hard
coded setting req.count = 1 during initial field setup before the main
loop.  This missed a subtlety that an early exit from the loop when
there are no ioreqs to process, would have req.count == 0 for the return
value.  handle_buffered_io() would then remove state->buffered_io_timer.
Instead handle_buffered_iopage() is basically always returning true and
handle_buffered_io() always re-setting the timer.

Restore the disabling of the timer by introducing a new handled_ioreq
boolean and use as the return value.  The named variable will more
clearly show the intent of the code.

Vladimir Sementsov-Ogievskiy 761a1a488e qapi: generate trace events by default
We don't generate trace events for tests/ and qga/ because that it is
not simple and not necessary. We have corresponding comments in both
tests/meson.build and qga/meson.build.

Still to not miss possible future qapi code generation call, and not to
forget to enable trace events generation, let's enable it by default.
So, turn option --gen-trace into opposite --no-trace-events and use new
option only in tests/ and qga/ where we already have good comments why
we don't generate trace events code.

Note that this commit enables trace-events generation for qapi-gen.py
call from tests/qapi-schema/meson.build and storage-daemon/meson.build.
Still, both are kind of noop: tests/qapi-schema/ doesn't seem to
generate any QMP command code and no .trace-events files anyway,

Vladimir Sementsov-Ogievskiy 378dfa482d meson: document why we don't generate trace events for tests/ and qga/
Making trace generation work for tests/ and qga/ would involve some
Meson hackery to ensure we generate the trace-events files before
trace-tool uses them. Since we don't actually support tracing there
anyway, we bypass that problem.

Let's add corresponding comments.

Previous commits enabled trace events generation for most of QAPI
generated code (except for tests/ and qga/). Let's update documentation
to illustrate it.

Philippe Mathieu-Daudé b269a70810 exec/cpu: Make host pages variables / macros 'target agnostic'
"host" pages are related to the *host* not the *target*,
thus the qemu_host_page_size / qemu_host_page_mask variables
and the HOST_PAGE_ALIGN() / REAL_HOST_PAGE_ALIGN() macros
can be moved to "exec/cpu-common.h" which is target agnostic.
