Set the TIR default value with the SMT thread index, and place some
standard limits on SMT configurations. Now powernv is able to boot
skiboot and Linux with a SMT topology, including booting a KVM guest.
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
added incrementally.

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.

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.

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 \

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.

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

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.

Convert the u2f.txt file to rST, and place it in the right place
in our manual layout. The old text didn't fit very well into our
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.

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.

The 3 high memory regions are usually enabled by default, but they may
be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2.
This leads to waste in the PA space.
Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to
allow users selectively disable them if needed. After that, the high
memory region for GICv3 or GICv4 redistributor can be disabled by user,
the number of maximal supported CPUs needs to be calculated based on
'vms->highmem_redists'. The follow-up error message is also improved
to indicate if the high memory region for GICv3 and GICv4 has been
enabled or not.

After the improvement to high memory region address assignment is
applied, the memory layout can be changed, introducing possible
migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region
is disabled or enabled when the optimization is applied or not, with
the following configuration. The configuration is only achievable by
modifying the source code until more properties are added to allow
users selectively disable those high memory regions.
pa_bits = 40;
vms->highmem_redists = false;
vms->highmem_ecam = false;
vms->highmem_mmio = true;
# qemu-system-aarch64 -accel kvm -cpu host \
-machine virt-7.2,compact-highmem={on, off} \
-m 4G,maxmem=511G -monitor stdio
Region compact-highmem=off compact-highmem=on
----------------------------------------------------------------
MEM [1GB 512GB] [1GB 512GB]
HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled]
HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled]
HIGH_PCIE_MMIO [disabled] [512GB 1TB]
In order to keep backwords compatibility, we need to disable the
optimization on machine, which is virt-7.1 or ealier than it. It
means the optimization is enabled by default from virt-7.2. Besides,
'compact-highmem' property is added so that the optimization can be
explicitly enabled or disabled on all machine types by users.

The architectural feature FEAT_ETS (Enhanced Translation
Synchronization) is a set of tightened guarantees about memory
ordering involving translation table walks:
* if memory access RW1 is ordered-before memory access RW2 then it
is also ordered-before any translation table walk generated by RW2
that generates a translation fault, address size fault or access
fault
* TLB maintenance on non-exec-permission translations is guaranteed
complete after a DSB (ie it does not need the context
synchronization event that you have to have if you don’t have
FEAT_ETS)
For QEMU’s implementation we don’t reorder translation table walk
accesses, and we guarantee to finish the TLB maintenance as soon as
the TLB op is done (the tlb_flush functions will complete at the end
of the TLB, and TLB ops always end the TB because they’re sysreg
writes).
So we’re already compliant and all we need to do is say so in the ID
registers for the 'max' CPU.

kaslr-seed. It then changes the name of the disabling option to reflect
that this has more to do with randomness vs determinism, rather than
something particular about kaslr.

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

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.

The Armv8.4 feature FEAT_IDST specifies that exceptions generated by
read accesses to the feature ID space should report a syndrome code
of 0x18 (EC_SYSTEMREGISTERTRAP) rather than 0x00 (EC_UNCATEGORIZED).
The feature ID space is defined to be:
op0 == 3, op1 == {0,1,3}, CRn == 0, CRm == {0-7}, op2 == {0-7}
In our implementation we might return the EC_UNCATEGORIZED syndrome
value for a system register access in four cases:
* no reginfo struct in the hashtable
* cp_access_ok() fails (ie ri->access doesn't permit the access)
* ri->accessfn returns CP_ACCESS_TRAP_UNCATEGORIZED at runtime
* ri->type includes ARM_CP_RAISES_EXC, and the readfn raises
an UNDEF exception at runtime
We have very few regdefs that set ARM_CP_RAISES_EXC, and none of
them are in the feature ID space. (In the unlikely event that any
are added in future they would need to take care of setting the
correct syndrome themselves.) This patch deals with the other
three cases, and enables FEAT_IDST for AArch64 -cpu max.

Imply the TPM sysbus devices. This allows users to add TPM devices to
the RISC-V virt board.
This was tested by first creating an emulated TPM device:
swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \
--ctrl type=unixio,path=swtpm-sock
Then launching QEMU with:
-chardev socket,id=chrtpm,path=swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-tis-device,tpmdev=tpm0
The TPM device can be seen in the memory tree and the generated device
tree.

The description in the Arm ARM of the requirements of FEAT_BBM is
admirably clear on the guarantees it provides software, but slightly
more obscure on what that means for implementations. The description
of the equivalent SMMU feature in the SMMU specification (IHI0070D.b
section 3.21.1) is perhaps a bit more detailed and includes some
example valid implementation choices. (The SMMU version of this
feature is slightly tighter than the CPU version: the CPU is permitted
to raise TLB Conflict aborts in some situations that the SMMU may
not. This doesn't matter for QEMU because we don't want to do TLB
Conflict aborts anyway.)
The informal summary of FEAT_BBM is that it is about permitting an OS
to switch a range of memory between "covered by a huge page" and
"covered by a sequence of normal pages" without having to engage in
the 'break-before-make' dance that has traditionally been
necessary. The 'break-before-make' sequence is:
* replace the old translation table entry with an invalid entry
* execute a DSB insn
* execute a broadcast TLB invalidate insn
* execute a DSB insn
* write the new translation table entry
* execute a DSB insn
The point of this is to ensure that no TLB can simultaneously contain
TLB entries for the old and the new entry, which would traditionally
be UNPREDICTABLE (allowing the CPU to generate a TLB Conflict fault
or to use a random mishmash of values from the old and the new
entry). FEAT_BBM level 2 says "for the specific case where the only
thing that changed is the size of the block, the TLB is guaranteed
not to do weird things even if there are multiple entries for an
address", which means that software can now do:
* replace old translation table entry with new entry
* DSB
* broadcast TLB invalidate
* DSB
As the SMMU spec notes, valid ways to do this include:
* if there are multiple entries in the TLB for an address,
choose one of them and use it, ignoring the others
* if there are multiple entries in the TLB for an address,
throw them all out and do a page table walk to get a new one
QEMU's page table walk implementation for Arm CPUs already meets the
requirements for FEAT_BBM level 2. When we cache an entry in our TCG
TLB, we do so only for the specific (non-huge) page that the address
is in, and there is no way for the TLB data structure to ever have
more than one TLB entry for that page. (We handle huge pages only in
that we track what part of the address space is covered by huge pages
so that a TLB invalidate operation for an address in a huge page
results in an invalidation of the whole TLB.) We ignore the Contiguous
bit in page table entries, so we don't have to do anything for the
parts of FEAT_BBM that deal with changis to the Contiguous bit.
FEAT_BBM level 2 also requires that the nT bit in block descriptors
must be ignored; since commit 39a1fd2528 we do this.
It's therefore safe for QEMU to advertise FEAT_BBM level 2 by
setting ID_AA64MMFR2_EL1.BBM to 2.

The Arm FEAT_TTL architectural feature allows the guest to provide an
optional hint in an AArch64 TLB invalidate operation about which
translation table level holds the leaf entry for the address being
invalidated. QEMU's TLB implementation doesn't need that hint, and
we correctly ignore the (previously RES0) bits in TLB invalidate
operation values that are now used for the TTL field. So we can
simply advertise support for it in our 'max' CPU.

Add support for the TCG GICv4 to the virt board. For the board,
the GICv4 is very similar to the GICv3, with the only difference
being the size of the redistributor frame. The changes here are thus:
* calculating virt_redist_capacity correctly for GICv4
* changing various places which were "if GICv3" to be "if not GICv2"
* the commandline option handling
Note that using GICv4 reduces the maximum possible number of CPUs on
the virt board from 512 to 317, because we can now only fit half as
many redistributors into the redistributor regions we have defined.

This feature widens physical addresses (and intermediate physical
addresses for 2-stage translation) from 48 to 52 bits, when using
4k or 16k pages.
This introduces the DS bit to TCR_ELx, which is RES0 unless the
page size is enabled and supports LPA2, resulting in the effective
value of DS for a given table walk. The DS bit changes the format
of the page table descriptor slightly, moving the PS field out to
TCR so that all pages have the same sharability and repurposing
those bits of the page table descriptor for the highest bits of
the output address.
Do not yet enable FEAT_LPA2; we need extra plumbing to avoid
tickling an old kernel bug.

Generally a guest needs an external source of randomness to properly
enable things like address space randomisation. However in a trusted
boot environment where the firmware will cryptographically verify
components having random data in the DTB will cause verification to
fail. Add a control knob so we can prevent this being added to the
system DTB.

In the discussion about renaming the `tests/acceptance` [1], the

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the

The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.
This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.
Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.

Currently, cpu-models-x86.rst.inc is included in target-i386.rst directly.
To make the toctree more homogeneous when adding more documentation,
include it through a first-class .rst file.
Together with the previous changes to the man page skeletons, this also
frees "===" for the headings, so that cpu-models-x86.rst.inc need not
assume anything about the headings used by target-i386.rst.

Man pages in docs/system use file inclusion heavily. Use headings with
overlines in the main files, so that the same included file work well
from both manuals and man pages.
This style of heading is a bit more heavy-weight, so it is not used by
the other man pages in interop/ and tools/. If in the future they
are changed to use include files, for example to avoid having sections
named "synopsis" or "description", they can switch to --- with overline
as well.

Use a standard heading format for the index.rst file in a directory.
Using overlines makes it clear that individual documents can use e.g.
=== for chapter titles and --- for section titles, as suggested in the
Linux kernel guidelines[1]. They could do it anyway, because documents
included in a toctree are parsed separately and therefore are not tied
to the same conventions for headings. However, keeping some consistency is
useful since sometimes files are included from multiple places.

Documents within a Sphinx manual are separate files and therefore can use
different conventions for headings. However, keeping some consistency is
useful so that included files are easy to get right.
This patch uses a standard heading format for book titles, so that it is
obvious when a file sits at the top level toctree of a book or man page.
The heading is irrelevant for man pages, but keep it consistent as well.

With gdb 9.0 and better it is possible to connect to a gdbstub
over unix sockets, which is better than a TCP socket connection
in some situations. The QEMU command line to set this up is
non-obvious; document it.

In rST markup, single backticks `like this` represent "interpreted
text", which can be handled as a bunch of different things if tagged
with a specific "role":
https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#interpreted-text
(the most common one for us is "reference to a URL, which gets
hyperlinked").
The default "role" if none is specified is "title_reference",
intended for references to book or article titles, and it renders
into the HTML as <cite>...</cite> (usually comes out as italics).
This commit fixes various places in the manual which were
using single backticks when double backticks (for literal text)
were intended, and covers those files where only one or two
instances of these errors were made.

Our built HTML documentation now has a standard footer which
gives the license for QEMU (and its documentation as a whole).
In almost all pages, we either don't bother to state the
copyright/license for the individual rST sources, or we put
it in an rST comment. There are just three pages which render
copyright or license information into the user-visible HTML.
Quoting a specific (different) license for an individual HTML
page within the manual is confusing. Downgrade the license
and copyright info to a comment within the rST source, bringing
these pages in line with the rest of our documents.
