Cédric Le Goater c7e313ae51 aspeed: Create flash devices only when defaults are enabled
When the -nodefaults option is set, flash devices should be created
with :

    -blockdev node-name=fmc0,driver=file,filename=./flash.img \
    -device mx66u51235f,cs=0x0,bus=ssi.0,drive=fmc0 \

To be noted that in this case, the ROM will not be installed and the
initial boot sequence (U-Boot loading) will fetch instructions using
SPI transactions which is significantly slower. That's exactly how HW
operates though.

Philippe Mathieu-Daudé b91b0fc163 accel: Remove HAX accelerator
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort
HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark
HAXM in QEMU as deprecated"), released in v8.0.0.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:

  Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.

The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:

  HAXM v7.8.0 is our last release and we will not accept
  pull requests or respond to issues after this.

It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help.  It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

Daniel Henrique Barboza 542c8776ca docs/system/target-riscv.rst: tidy CPU firmware section
This is how the content of the "RISC-V CPU firmware" section is
displayed after the html is generated:

"When using the sifive_u or virt machine there are three different
firmware boot options: 1. -bios default - This is the default behaviour
if no -bios option is included. (...) 3. -bios <file> - Tells QEMU to
load the specified file as the firmware."

It's all in the same paragraph, in a numbered list, and no special
formatting for the options.

Tidy it a bit by adding line breaks between items and its description.
Remove the numbered list. And apply formatting for the options cited in
the middle of the text.

There are several SPRs and other features (e.g., broadcast msgsnd)
that are not implemented, but not used by OPAL or Linux and can be

Yuquan Wang 62c2b8760b hw/arm/sbsa-ref: use XHCI to replace EHCI
The current sbsa-ref cannot use EHCI controller which is only
able to do 32-bit DMA, since sbsa-ref doesn't have RAM below 4GB.
Hence, this uses XHCI to provide a usb controller with 64-bit
DMA capablity instead of EHCI.

We bump the platform version to 0.3 with this change.  Although the
hardware at the USB controller address changes, the firmware and
Linux can both cope with this -- on an older non-XHCI-aware
firmware/kernel setup the probe routine simply fails and the guest
proceeds without any USB.  (This isn't a loss of functionality,
because the old USB controller never worked in the first place.) So
we can call this a backwards-compatible change and only bump the
minor version.

Ilya Leoshkevich abf7ba310b docs: Document security implications of debugging
Now that the GDB stub explicitly implements reading host files (note
that it was already possible by changing the emulated code to open and
read those files), concerns may arise that it undermines security.

Document the status quo, which is that the users are already
responsible for securing the GDB connection themselves.

Henrik Carlqvist 6b90a4cdc0 escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout.  Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.

Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:

-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es

But the patch also accepts numeric dip switch values directly:

-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43

Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html

Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:

qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin

If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

Vikram Garhwal 733766cd37 hw/arm: introduce xenpvh machine
Add a new machine xenpvh which creates a IOREQ server to register/connect with
Xen Hypervisor.

Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a
TPM emulator and connects to swtpm running on host machine via chardev socket
and support TPM functionalities for a guest domain.

Extra command line for aarch64 xenpvh QEMU to connect to swtpm:
    -chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \
    -tpmdev emulator,id=tpm0,chardev=chrtpm \
    -machine tpm-base-addr=0x0c000000 \

swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and
provides access to TPM functionality over socket, chardev and CUSE interface.
Github repo: https://github.com/stefanberger/swtpm
Example for starting swtpm on host machine:
    mkdir /tmp/vtpm2
    swtpm socket --tpmstate dir=/tmp/vtpm2 \
    --ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &

Cédric Le Goater f65f6ad5a7 aspeed: Introduce a "bmc-console" machine option
Most of the Aspeed machines use the UART5 device for the boot console,
and QEMU connects the first serial Chardev to this SoC device for this
purpose. See routine connect_serial_hds_to_uarts().

Nevertheless, some machines use another boot console, such as the fuji,
and commit 5d63d0c76c ("hw/arm/aspeed: Allow machine to set UART
default") introduced a SoC class attribute 'uart_default' and property
to be able to change the boot console device. It was later changed by
commit d2b3eaefb4 ("aspeed: Refactor UART init for multi-SoC machines").

The "bmc-console" machine option goes a step further and lets the user define
the UART device from the QEMU command line without introducing a new
machine definition. For instance, to use device UART3 (mapped on
/dev/ttyS2 under Linux) instead of the default UART5, one would use :

  -M ast2500-evb,bmc-console=uart3

Gregory Price adacc814f5 hw/cxl: Multi-Region CXL Type-3 Devices (Volatile and Persistent)
This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.

Two new properties have been added to cxl-type3 device initialization:
    [volatile-memdev] and [persistent-memdev]

The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.

Partitioning volatile memory from persistent memory is not yet supported.

Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

manual style, so the new version ends up looking like a rewrite,
although some of the original text is preserved:

 * the 'building' section of the old file is removed, since we
   generally assume that users have already built QEMU
 * some rather verbose text has been cut back
 * document the passthrough device first, on the assumption
   that's most likely to be of interest to users
 * cut back on the duplication of text between sections
 * format example command lines etc with rST

As it's a short document it seemed simplest to do this all
in one go rather than try to do a minimal syntactic conversion
and then clean up the wording and layout.

Peter Maydell d6359e150d docs: Remove unused weirdly-named cross-reference targets
In the doc sources, we have a few cross-reference targets with odd
names "pcsys_005fxyz".  These are the legacy of the semi-automated
conversion of the old info docs to rST (the '005f' is because ASCII
0x5f is '_' and the old info link names had underscores in them).

Remove the targets which nothing links to, and rename the two targets
which are used to something a bit more descriptive.

Peter Maydell dd17143fce target/arm: Implement FEAT_PAN3
FEAT_PAN3 adds an EPAN bit to SCTLR_EL1 and SCTLR_EL2, which allows
the PAN bit to make memory non-privileged-read/write if it is
user-executable as well as if it is user-read/write.

Implement this feature and enable it in the AArch64 'max' CPU.
