In Linux, a check is applied to every device which is exposed through
device-tree node. The warning message is raised when the device isn't
DMA coherent and the cache line size is larger than ARCH_DMA_MINALIGN
(128 bytes). The cache line is sorted from CTR_EL0[CWG], which corresponds
to 256 bytes on the guest CPUs. The DMA coherent capability is claimed
through 'dma-coherent' in their device-tree nodes or parent nodes.
This happens even when the device doesn't implement or use DMA at all,
for legacy reasons.

Fix the issue by adding 'dma-coherent' property to the device-tree root
node, meaning all devices are capable of DMA coherent by default.
This both suppresses the spurious kernel warnings and also guards
against possible future QEMU bugs where we add a DMA-capable device
and forget to mark it as dma-coherent.

hw/arm/virt: allow creation of a second NonSecure UART

For some use-cases, it is helpful to have more than one UART
available to the guest.  If the second UART slot is not already used
for a TrustZone Secure-World-only UART, create it as a NonSecure UART
only when the user provides a serial backend (e.g.  via a second
-serial command line option).

This avoids problems where existing guest software only expects a
single UART, and gets confused by the second UART in the DTB.  The
major example of this is older EDK2 firmware, which will send the
GRUB bootloader output to UART1 and the guest serial output to UART0.
Users who want to use both UARTs with a guest setup including EDK2
are advised to update to EDK2 release edk2-stable202311 or newer.
(The prebuilt EDK2 blobs QEMU upstream provides are new enough.)
The relevant EDK2 changes are the ones described here:

hw/arm/virt: Add serial aliases in DTB

If there is more than one UART in the DTB, then there is no guarantee
on which order a guest is supposed to initialise them.  The standard
solution to this is "serialN" entries in the "/aliases" node of the
dtb which give the nodename of the UARTs.

At the moment we only have two UARTs in the DTB when one is for
the Secure world and one for the Non-Secure world, so this isn't
really a problem. However if we want to add a second NS UART we'll
need the aliases to ensure guests pick the right one.

hw/usb/hcd-dwc2: Handle invalid address access in read and write functions

This commit modifies the dwc2_hsotg_read() and dwc2_hsotg_write() functions
to handle invalid address access gracefully. Instead of using
g_assert_not_reached(), which causes the program to abort, the functions
now log an error message and return a default value for reads or do
nothing for writes.

This change prevents the program from aborting and provides clear log
messages indicating when an invalid memory address is accessed.

scripts/coverity-scan/COMPONENTS.md: Update paths to match gitlab CI

Since commit 83aa1baa069c we have been running the build for Coverity
Scan as a Gitlab CI job, rather than the old setup where it was run
on a local developer's machine.  This is working well, but the
absolute paths of files are different for the Gitlab CI job, which
means that the regexes we use to identify Coverity components no
longer work. With Gitlab CI builds the file paths are of the form
 /builds/qemu-project/qemu/accel/kvm/kvm-all.c

rather than the old
 /qemu/accel/kvm/kvm-all.c

and our regexes all don't match.

Update all the regexes to start with .*/qemu/ . This will hopefully
avoid the need to change them again in future if the build path
changes again.

This change was made with a search-and-replace of (/qemu)?
to .*/qemu .

hw/intc/arm_gic: Fix deactivation of SPI lines

Julien reported that he has seen strange behaviour when running
Xen on QEMU using GICv2. When Xen migrates a guest's vCPU from
one pCPU to another while the vCPU is handling an interrupt, the
guest is unable to properly deactivate interrupts.

Looking at it a little closer, our GICv2 model treats
deactivation of SPI lines as if they were PPI's, i.e banked per
CPU core. The state for active interrupts should only be banked
for PPI lines, not for SPI lines.

Make deactivation of SPI lines unbanked, similar to how we
handle writes to GICD_ICACTIVER.

linux-user: Make TARGET_NR_setgroups affect only the current thread

Like TARGET_NR_setuid, TARGET_NR_setgroups should affect only the
calling thread, and not the entire process. Therefore, implement it
using a syscall, and not a libc call.

hw/intc: Introduce x-query-interrupt-controllers QMP command

This is a counterpart to the HMP "info pic" command. It is being
added with an "x-" prefix because this QMP command is intended as an
adhoc debugging tool and will thus not be modelled in QAPI as fully
structured data, nor will it have long term guaranteed stability.
The existing HMP command is rewritten to call the QMP command.
