The oldest model that IBM still supports is the z13. Considering
that each generation can "emulate" the previous two generations
in hardware (via the "IBC" feature of the CPUs), this means that
everything that is older than z114/196 is not an officially supported
CPU model anymore. The Linux kernel still support the z10, so if
we also take this into account, everything older than that can
definitely be considered as a legacy CPU model.
For downstream builds of QEMU, we would like to be able to disable
these legacy CPUs in the build. Thus add a CONFIG switch that can be
used to disable them (and old machine types that use them by default).

This changes the way the ohci emulation handles a Transfer Descriptor
with "Buffer End" set to "Current Buffer Pointer" - 1, specifically
in the case of a zero-length packet.
The OHCI spec 4.3.1.2 Table 4-2 specifies td.cbp to be zero for a
zero-length packet. Peter Maydell tracked down commit 1328fe0c32
(hw: usb: hcd-ohci: check len and frame_number variables) where qemu
started checking this according to the spec.
What this patch does is loosen the qemu ohci implementation to allow a
zero-length packet if td.be (Buffer End) is set to td.cbp - 1, and with a
non-zero td.cbp value.
The spec is unclear whether this is valid or not -- it is not the
clearly documented way to send a zero length TD (which is CBP=BE=0),
but it isn't specifically forbidden. Actual hw seems to be ok with it.
Does any OS rely on this behavior? There have been no reports to
qemu-devel of this problem.
This is attempting to have qemu behave like actual hardware,
but this is just a minor change.
With a tiny OS[1] that boots and executes a test, the issue can be seen:
* OS that sends USB requests to a USB mass storage device
but sends td.cbp = td.be + 1
* qemu 4.2
* qemu HEAD (4e66a0854)
* Actual OHCI controller (hardware)
Command line:
qemu-system-x86_64 -m 20 \
-device pci-ohci,id=ohci \
-drive if=none,format=raw,id=d,file=testmbr.raw \
-device usb-storage,bus=ohci.0,drive=d \
--trace "usb_*" --trace "ohci_*" -D qemu.log
Results are:
qemu 4.2 | qemu HEAD | actual HW
-----------+------------+-----------
works fine | ohci_die() | works fine
Tip: if the flags "-serial pty -serial stdio" are added to the command line
the test will output USB requests like this:
Testing qemu HEAD:
> Free mem 2M ohci port2 conn FS
> setup { 80 6 0 1 0 0 8 0 }

According to the User Manual Section 25.3[1], the registers for RNG operations

RNG module enforce the correct access sizes, preventing invalid memory accesses.

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.

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:

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.

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.

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.
