hw/intc: sifive_plic: Avoid overflowing the addr_config buffer
Since commit ad40be27 "target/riscv: Support start kernel directly by
KVM" we have been overflowing the addr_config on "M,MS..."
configurations, as reported https://gitlab.com/qemu-project/qemu/-/issues/1050.
This commit changes the loop in sifive_plic_create() from iterating over
the number of harts to just iterating over the addr_config. The
addr_config is based on the hart_config, and will contain interrup details
for all harts. This way we can't iterate past the end of addr_config.
Fixes: ad40be27084536 ("target/riscv: Support start kernel directly by KVM")

hw/riscv: virt: Generate fw_cfg DT node correctly
fw_cfg DT node is generated after the create_fdt without any check
if the DT is being loaded from the commandline. This results in
FDT_ERR_EXISTS error if dtb is loaded from the commandline.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
This function was declared in a generic and public header, implemented
in a device-specific source file but only used in xen_platform. Given its
'aux' parameter, this function is more xen-specific than piix-specific.
Also, the hardcoded magic constants seem to be generic and related to
PCIIDEState and IDEBus rather than piix.
Therefore, move this function to xen_platform, unexport it, and drop the
"piix3" in the function name as well.

target/arm: Use uint32_t instead of bitmap for sve vq's
The bitmap need only hold 15 bits; bitmap is over-complicated.
We can simplify operations quite a bit with plain logical ops.
The introduction of SVE_VQ_POW2_MAP eliminates the need for
looping in order to search for powers of two. Simply perform
the logical ops and use count leading or trailing zeros as
required to find the result.

xlnx-zynqmp: fix the irq mapping for the display port and its dma
When the display port has been initially implemented the device

waits for vblank interrupt it has been noticed that the irq mapping
is wrong. So use the value from the linux device tree and the

target/arm: Implement FEAT_DoubleFault
The FEAT_DoubleFault extension adds the following:
* All external aborts on instruction fetches and translation table
walks for instruction fetches must be synchronous. For QEMU this
is already true.
* SCR_EL3 has a new bit NMEA which disables the masking of SError
interrupts by PSTATE.A when the SError interrupt is taken to EL3.
For QEMU we only need to make the bit writable, because we have no
sources of SError interrupts.
* SCR_EL3 has a new bit EASE which causes synchronous external
aborts taken to EL3 to be taken at the same entry point as SError.
(Note that this does not mean that they are SErrors for purposes
of PSTATE.A masking or that the syndrome register reports them as
SErrors: it just means that the vector offset is different.)
* The existing SCTLR_EL3.IESB has an effective value of 1 when
SCR_EL3.NMEA is 1. For QEMU this is a no-op because we don't need
different behaviour based on IESB (we don't need to do anything to
ensure that error exceptions are synchronized).
So for QEMU the things we need to change are:
* Make SCR_EL3.{NMEA,EASE} writable
* When taking a synchronous external abort at EL3, adjust the
vector entry point if SCR_EL3.EASE is set
* Advertise the feature in the ID registers

target/arm: Declare support for FEAT_RASv1p1
The architectural feature RASv1p1 introduces the following new
features:
* new registers ERXPFGCDN_EL1, ERXPFGCTL_EL1 and ERXPFGF_EL1
* new bits in the fine-grained trap registers that control traps
for these new registers
* new trap bits HCR_EL2.FIEN and SCR_EL3.FIEN that control traps
for ERXPFGCDN_EL1, ERXPFGCTL_EL1, ERXPFGP_EL1
* a larger number of the ERXMISC<n>_EL1 registers
* the format of ERR<n>STATUS registers changes
The architecture permits that if ERRIDR_EL1.NUM is 0 (as it is for
QEMU) then all these new registers may UNDEF, and the HCR_EL2.FIEN
and SCR_EL3.FIEN bits may be RES0. We don't have any ERR<n>STATUS
registers (again, because ERRIDR_EL1.NUM is 0). QEMU does not yet
implement the fine-grained-trap extension. So there is nothing we
need to implement to be compliant with the feature spec. Make the
'max' CPU report the feature in its ID registers, and document it.

At the moment, there doesn't seems to be any way to know that QEMU

on Xen while migrating a guest, as modification to the buffer after
the migration as started could be ignored and not transfered to the
