Hi,
There are two parts to this series, broadly related because they are
all to do with Xen. The first half is a re-spin of the guest-loader
patches from a few weeks ago. The only changes are to move the
generic-loader documentation into the manual and then add some words
about the guest-loader.
The second half of the series is an attempt to fix and then clean up
the handling of Xen enabled builds. Recent changes to the build system
broke the ability to build qemu-system-i386 on arm64 hosts with Xen
support enabled. The actual fix for that:
meson.build: fix building of Xen support for aarch64
should probably be rolled into the current release as it fixes a
regression. The rest can wait until the tree re-opens. The patches
broadly try to:
- clean-up detection and reporting
- be more explicit about linking stubs for accel
- add an explicit CONFIG_XEN_HVM for x86
and finally allow you to build a qemu-system-aarch64 with Xen support.
This is my first major foray into tweaking meson builds and it seems
to occasionally come unstuck and requires a distclean and re-configure
to un-wedge itself. The following need review:
- meson.build: build a Xen aware qemu-aarch64-system
- xen: only build HVM support under CONFIG_XEN_HVM
- accel/stubs: drop unused cpu.h include
- stubs/xen-hw-stub: drop xenstore_store_pv_console_info stub
- include/hw/xen.h: drop superfluous struct
- meson.build: clean-up summary reporting of XEN and it's features
- meson.build: introduce CONFIG_XEN_HVM flag
- meson.build: fix building of Xen support for aarch64
- accel/meson: you only need accelerator stubs for softmmu builds
- docs: add some documentation for the guest-loader
- docs: move generic-loader documentation into the main manual

The use of FDT's is quite common across our various platforms. To
allow the generic loader to tweak it we need to make it available in
the generic state. This creates the field and migrates the initial
user to use the generic field. Other boards will be updated in later
patches.

A string array in device tree is simply a series of \0 terminated
strings next to each other. As libfdt doesn't support that directly
we need to build it ourselves.

Hypervisors, especially type-1 ones, need the firmware/bootcode to put
their initial guest somewhere in memory and pass the information to it
via platform data. The guest-loader is modelled after the generic
loader for exactly this sort of purpose:
$QEMU $ARGS -kernel ~/xen.git/xen/xen \
-append "dom0_mem=1G,max:1G loglvl=all guest_loglvl=all" \
-device guest-loader,addr=0x42000000,kernel=Image,bootargs="root=/dev/sda2 ro console=hvc0 earlyprintk=xen" \
-device guest-loader,addr=0x47000000,initrd=rootfs.cpio

We might as well surface this useful information in the manual so
users can find it easily. It is a fairly simple conversion to rst with
the only textual fixes being QemuOps to QemuOpts.

-The 'loader' device allows the user to load multiple images or values into
-QEMU at startup.
-
-Loading Data into Memory Values
--------------------------------
-The loader device allows memory values to be set from the command line. This
-can be done by following the syntax below:
-
- -device loader,addr=<addr>,data=<data>,data-len=<data-len>
- [,data-be=<data-be>][,cpu-num=<cpu-num>]
-
- <addr> - The address to store the data in.
- <data> - The value to be written to the address. The maximum size of
- the data is 8 bytes.
- <data-len> - The length of the data in bytes. This argument must be
- included if the data argument is.
- <data-be> - Set to true if the data to be stored on the guest should be
- written as big endian data. The default is to write little
- endian data.
- <cpu-num> - The number of the CPU's address space where the data should
- be loaded. If not specified the address space of the first
- CPU is used.
-
-All values are parsed using the standard QemuOps parsing. This allows the user
-to specify any values in any format supported. By default the values
-will be parsed as decimal. To use hex values the user should prefix the number
-with a '0x'.
-
-An example of loading value 0x8000000e to address 0xfd1a0104 is:
- -device loader,addr=0xfd1a0104,data=0x8000000e,data-len=4
-
-Setting a CPU's Program Counter
--------------------------------
-The loader device allows the CPU's PC to be set from the command line. This
-can be done by following the syntax below:
-
- -device loader,addr=<addr>,cpu-num=<cpu-num>
-
- <addr> - The value to use as the CPU's PC.

-
-Loading Files
--------------
-The loader device also allows files to be loaded into memory. It can load ELF,
-U-Boot, and Intel HEX executable formats as well as raw images. The syntax is
-shown below:
-
- -device loader,file=<file>[,addr=<addr>][,cpu-num=<cpu-num>][,force-raw=<raw>]
-
- <file> - A file to be loaded into memory
- <addr> - The memory address where the file should be loaded. This is
- required for raw images and ignored for non-raw files.
- <cpu-num> - This specifies the CPU that should be used. This is an
- optional argument and will cause the CPU's PC to be set to
- the memory address where the raw file is loaded or the entry
- point specified in the executable format header. This option
- should only be used for the boot image.
- This will also cause the image to be written to the specified
- CPU's address space. If not specified, the default is CPU 0.
- <force-raw> - Setting force-raw=on forces the file to be treated as a raw
- image. This can be used to load supported executable formats
- as if they were raw.
-
-All values are parsed using the standard QemuOps parsing. This allows the user
-to specify any values in any format supported. By default the values

-An example of loading an ELF file which CPU0 will boot is shown below:
- -device loader,file=./images/boot.elf,cpu-num=0
-
-Restrictions and ToDos
-----------------------
- - At the moment it is just assumed that if you specify a cpu-num then you
- want to set the PC as well. This might not always be the case. In future
- the internal state 'set_pc' (which exists in the generic loader now) should
- be exposed to the user so that they can choose if the PC is set or not.

+
+Guest Loader
+------------
+
+The guest loader is similar to the `generic-loader` although it is
+aimed at a particular use case of loading hypervisor guests. This is
+useful for debugging hypervisors without having to jump through the
+hoops of firmware and boot-loaders.
+
+The guest loader does two things:
+
+ - load blobs (kernels and initial ram disks) into memory
+ - sets platform FDT data so hypervisors can find and boot them
+
+This is what is typically done by a boot-loader like grub using it's
+multi-boot capability. A typical example would look like:
+
+.. parsed-literal::
+
+ |qemu_system| -kernel ~/xen.git/xen/xen \
+ -append "dom0_mem=1G,max:1G loglvl=all guest_loglvl=all" \
+ -device guest-loader,addr=0x42000000,kernel=Image,bootargs="root=/dev/sda2 ro console=hvc0 earlyprintk=xen" \
+ -device guest-loader,addr=0x47000000,initrd=rootfs.cpio
+
+In the above example the Xen hypervisor is loaded by the -kernel
+parameter and passed it's boot arguments via -append. The Dom0 guest
+is loaded into the areas of memory. Each blob will get
+`/chosen/module@<addr>` entry in the FDT to indicate it's location and
+size. Additional information can be passed with by using additional
+arguments.
+
+Currently the only supported machines which use FDT data to boot are
+the ARM and RiscV `virt` machines.
+
+Arguments
+^^^^^^^^^
+
+The full syntax of the guest-loader is::
+
+ -device guest-loader,addr=<addr>[,kernel=<file>,[bootargs=<args>]][,initrd=<file>]
+
+``addr=<addr>``
+ This is mandatory and indicates the start address of the blob.
+
+``kernel|initrd=<file>``
+ Indicates the filename of the kernel or initrd blob. Both blobs will
+ have the "multiboot,module" compatibility string as well as
+ "multiboot,kernel" or "multiboot,ramdisk" as appropriate.
+
+``bootargs=<args>``
+ This is an optional field for kernel blobs which will pass command
+ like via the `/chosen/module@<addr>/bootargs` node.

This avoids us pulling in Xen headers we don't need. The TCG
accelerator will always exist for the *-user builds.

Xen is supported on ARM although weirdly using the i386-softmmu model.
Checking based on the host CPU meant we never enabled Xen support. It
would be nice to enable CONFIG_XEN for aarch64-softmmu to make it not
seem weird but that will require further build surgery.

While Xen traditionally uses i386-softmmu to run it's PV models on all
architectures some models are very much x86 only. This includes the
full hardware virtualisation (HVM) which is only used on x86 HW. By
introducing the symbol we can also fix the inclusion of
XEN_PCI_PASSTHROUGH which should only be built for x86 (and Linux)
systems.

shuffle a little bit of the inline and other stubs about.

I'm confused while looking at
https://wiki.xen.org/wiki/Xen_Project_Software_Overview#ARM_Hosts
Maybe it makes sense to add both CONFIG_XEN_PV /
CONFIG_XEN_HVM accelerators?

Are you sure it is restricted to 64-bit host? I can't find
