Peter Maydell da4680ce3a hw/intc/arm_gicv3_its: Drop TableDesc and CmdQDesc valid fields
Currently we track in the TableDesc and CmdQDesc structs the state of
the GITS_BASER<n> and GITS_CBASER Valid bits.  However we aren't very
consistent abut checking the valid field: we test it in update_cte()
and update_dte(), but not anywhere else we look things up in tables.

The GIC specification says that it is UNPREDICTABLE if a guest fails
to set any of these Valid bits before enabling the ITS via
GITS_CTLR.Enabled.  So we can choose to handle Valid == 0 as
equivalent to a zero-length table.  This is in fact how we're already
catching this case in most of the table-access paths: when Valid is 0
we leave the num_entries fields in TableDesc or CmdQDesc set to zero,
and then the out-of-bounds check "index >= num_entries" that we have
to do anyway before doing any of these table lookups will always be
true, catching the no-valid-table case without any extra code.

So we can remove the checks on the valid field from update_cte()
and update_dte(): since these happen after the bounds check there
was never any case when the test could fail. That means the valid
fields would be entirely unused, so just remove them.

Peter Maydell d6dc926e6e hw/arm/boot: Drop nb_cpus field from arm_boot_info
We use the arm_boot_info::nb_cpus field in only one place, and that
place can easily get the number of CPUs locally rather than relying
on the board code to have set the field correctly.  (At least one
board, xlnx-versal-virt, does not set the field despite having more
than one CPU.)

Peter Maydell d4a29ed6db hw/arm/boot: Don't write secondary boot stub if using PSCI
If we're using PSCI emulation to start secondary CPUs, there is no
point in writing the "secondary boot" stub code, because it will
never be used -- secondary CPUs start powered-off, and when powered
on are set to begin execution at the address specified by the guest's
power-on PSCI call, not at the stub.

Move the call to the hook that writes the secondary boot stub code so
that we can do it only if we're starting a Linux kernel and not using
PSCI.

(None of the users of the hook care about the ordering of its call
relative to anything else: they only use it to write a rom blob to
guest memory.)

Peter Maydell 9437a76e10 hw/arm/versal: Let boot.c handle PSCI enablement
Instead of setting the CPU psci-conduit and start-powered-off
properties in the xlnx-versal-virt board code, set the arm_boot_info
psci_conduit field so that the boot.c code can do it.

This will fix a corner case where we were incorrectly enabling PSCI
emulation when booting guest code into EL3 because it was an ELF file
passed to -kernel.  (EL3 guest code started via -bios, -pflash, or
the generic loader was already being run with PSCI emulation
disabled.)

Note that EL3 guest code has no way to turn on the secondary CPUs
because there's no emulated power controller, but this was already
true for EL3 guest code run via -bios, -pflash, or the generic
loader.

Peter Maydell 817e2db8ce hw/arm/boot: Support setting psci-conduit based on guest EL
Currently we expect board code to set the psci-conduit property on
CPUs and ensure that secondary CPUs are created with the
start-powered-off property set to false, if the board wishes to use
QEMU's builtin PSCI emulation.  This worked OK for the virt board
where we first wanted to use it, because the virt board directly
creates its CPUs and is in a reasonable position to set those
properties.  For other boards which model real hardware and use a
separate SoC object, however, it is more awkward.  Most PSCI-using
boards just set the psci-conduit board unconditionally.

This was never strictly speaking correct (because you would not be
able to run EL3 guest firmware that itself provided the PSCI
interface, as the QEMU implementation would overrule it), but mostly
worked in practice because for non-PSCI SMC calls QEMU would emulate
the SMC instruction as normal (by trapping to guest EL3).  However,
we would like to make our PSCI emulation follow the part of the SMCC
specification that mandates that SMC calls with unknown function
identifiers return a failure code, which means that all SMC calls
will be handled by the PSCI code and the "emulate as normal" path
will no longer be taken.

We tried to implement that in commit 9fcd15b919
("arm: tcg: Adhere to SMCCC 1.3 section 5.2"), but this
regressed attempts to run EL3 guest code on the affected boards:
 * mcimx6ul-evk, mcimx7d-sabre, orangepi, xlnx-zcu102
 * for the case only of EL3 code loaded via -kernel (and
   not via -bios or -pflash), virt and xlnx-versal-virt
so for the 7.0 release we reverted it (in commit 4825eaae4f).

This commit provides a mechanism that boards can use to arrange that
psci-conduit is set if running guest code at a low enough EL but not
if it would be running at the same EL that the conduit implies that
the QEMU PSCI implementation is using.  (Later commits will convert
individual board models to use this mechanism.)

We do this by moving the setting of the psci-conduit and
start-powered-off properties to arm_load_kernel().  Boards which want
to potentially use emulated PSCI must set a psci_conduit field in the
arm_boot_info struct to the type of conduit they want to use (SMC or
HVC); arm_load_kernel() will then set the CPUs up accordingly if it
is not going to start the guest code at the same or higher EL as the
fake QEMU firmware would be at.

Board/SoC code which uses this mechanism should no longer set the CPU
psci-conduit property directly.  It should only set the
start-powered-off property for secondaries if EL3 guest firmware
running bare metal expects that rather than the alternative "all CPUs
start executing the firmware at once".

Note that when calculating whether we are going to run guest
code at EL3, we ignore the setting of arm_boot_info::secure_board_setup,
which might cause us to run a stub bit of guest code at EL3 which
does some board-specific setup before dropping to EL2 or EL1 to
run the guest kernel. This is OK because only one board that
enables PSCI sets secure_board_setup (the highbank board), and
the stub code it writes will behave the same way whether the
one SMC call it makes is handled by "emulate the SMC" or by
"PSCI default returns an error code". So we can leave that stub
code in place until after we've changed the PSCI default behaviour;
at that point we will remove it.

Kevin Wolf 520d8b40e8 block/export: Fix vhost-user-blk shutdown with requests in flight
The vhost-user-blk export runs requests asynchronously in their own
coroutine. When the vhost connection goes away and we want to stop the
vhost-user server, we need to wait for these coroutines to stop before
we can unmap the shared memory. Otherwise, they would still access the
unmapped memory and crash.

This introduces a refcount to VuServer which is increased when spawning
a new request coroutine and decreased before the coroutine exits. The
memory is only unmapped when the refcount reaches zero.

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.

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.

Troy Lee 119df56bf0 hw/misc/aspeed_i3c.c: Introduce a dummy AST2600 I3C model.
Aspeed 2600 SDK enables I3C support by default.  The I3C driver will try
to reset the device controller and set it up through device address table
register.  This dummy model responds to these registers with default values
as listed in the ast2600v10 datasheet chapter 54.2.

This avoids a guest machine kernel panic due to referencing an
invalid kernel address if the device address table register isn't
set correctly.

Alex Bennée 33973e1e1f hw/arm: add control knob to disable kaslr_seed via DTB
Generally a guest needs an external source of randomness to properly
enable things like address space randomisation. However in a trusted
boot environment where the firmware will cryptographically verify
components having random data in the DTB will cause verification to
fail. Add a control knob so we can prevent this being added to the
system DTB.

Daniel Henrique Barboza 3f4c369ea6 ppc/pnv: make PECs create and realize PHB4s
This patch changes the design of the PEC device to create and realize PHB4s
instead of PecStacks. After all the recent changes, PHB4s now contain all
the information needed for their proper functioning, not relying on PecStack
in any capacity.

All changes are being made in a single patch to avoid renaming parts of
the PecState and leaving the code in a strange way. E.g. rename
PecClass->num_stacks to num_phbs, which would then read a
pnv_pec_num_stacks[] array. To avoid mixing the old and new design more
than necessary it's clearer to do these changes in a single step.

The name changes made are:

- in PnvPhb4PecState:
  * rename 'num_stacks' to 'num_phbs'
  * remove the pec->stacks[] array. Current code relies on the
pec->stacks[] obj acting as a simple container, without ever accessing
pec->stacks[] for any other purpose. Instead of converting this into a
pec->phbs[] array, remove it

- in PnvPhb4PecClass, rename *num_stacks to *num_phbs;

- pnv_pec_num_stacks[] is renamed to pnv_pec_num_phbs[].

The logical changes:

- pnv_pec_default_phb_realize():
  * init and set the properties of the PnvPHB4 qdev
  * do not use stack->phb anymore;

- pnv_pec_realize():
  * use the new default_phb_realize() to init/realize each PHB if
running with defaults;

- pnv_pec_instance_init(): removed since we're creating the PHBs during
pec_realize();

- pnv_phb4_get_stack():
  * renamed to pnv_phb4_get_pec() and returns a PnvPhb4PecState*;

- pnv_phb4_realize(): use 'phb->pec' instead of 'stack'.

This design change shouldn't caused any behavioral change in the runtime
of the machine.
