f1826463d2 machine/nitro-enclave: New machine type for AWS Nitro Enclaves
AWS nitro enclaves[1] is an Amazon EC2[2] feature that allows creating
isolated execution environments, called enclaves, from Amazon EC2
instances which are used for processing highly sensitive data. Enclaves
have no persistent storage and no external networking. The enclave VMs
are based on the Firecracker microvm with a vhost-vsock device for
communication with the parent EC2 instance that spawned it and a Nitro
Secure Module (NSM) device for cryptographic attestation. The parent
instance VM always has CID 3 while the enclave VM gets a dynamic CID.

An EIF (Enclave Image Format)[3] file is used to boot an AWS nitro enclave
virtual machine. This commit adds support for AWS nitro enclave emulation
using a new machine type option '-M nitro-enclave'. This new machine type
is based on the 'microvm' machine type, similar to how real nitro enclave
VMs are based on Firecracker microvm. For nitro-enclave to boot from an
EIF file, the kernel and ramdisk(s) are extracted into a temporary kernel
and a temporary initrd file which are then hooked into the regular x86
boot mechanism along with the extracted cmdline. The EIF file path should
be provided using the '-kernel' QEMU option.

In QEMU, the vsock emulation for nitro enclave is added using vhost-user-
vsock as opposed to vhost-vsock. vhost-vsock doesn't support sibling VM
communication which is needed for nitro enclaves. So for the vsock
communication to CID 3 to work, another process that does the vsock
emulation in  userspace must be run, for example, vhost-device-vsock[4]
from rust-vmm, with necessary vsock communication support in another
guest VM with CID 3. Using vhost-user-vsock also enables the possibility
to implement some proxying support in the vhost-user-vsock daemon that
will forward all the packets to the host machine instead of CID 3 so
that users of nitro-enclave can run the necessary applications in their
host machine instead of running another whole VM with CID 3. The following
mandatory nitro-enclave machine option has been added related to the
vhost-user-vsock device.
  - 'vsock': The chardev id from the '-chardev' option for the
vhost-user-vsock device.

AWS Nitro Enclaves have built-in Nitro Secure Module (NSM) device which
has been added using the virtio-nsm device added in a previous commit.
In Nitro Enclaves, all the PCRs start in a known zero state and the first
16 PCRs are locked from boot and reserved. The PCR0, PCR1, PCR2 and PCR8
contain the SHA384 hashes related to the EIF file used to boot the VM
for validation. The following optional nitro-enclave machine options
have been added related to the NSM device.
  - 'id': Enclave identifier, reflected in the module-id of the NSM
device. If not provided, a default id will be set.
  - 'parent-role': Parent instance IAM role ARN, reflected in PCR3
of the NSM device.
  - 'parent-id': Parent instance identifier, reflected in PCR4 of the
NSM device.

bb154e3e0c device/virtio-nsm: Support for Nitro Secure Module device
Nitro Secure Module (NSM)[1] device is used in AWS Nitro Enclaves[2]
for stripped down TPM functionality like cryptographic attestation.
The requests to and responses from NSM device are CBOR[3] encoded.

This commit adds support for NSM device in QEMU. Although related to
AWS Nitro Enclaves, the virito-nsm device is independent and can be
used in other machine types as well. The libcbor[4] library has been
used for the CBOR encoding and decoding functionalities.

845b54efaf qom: remove unused function
The function has been unused since commit 4fa28f2390 ("ppc/pnv:
Instantiate cores separately", 2019-12-17).  The idea was that
you could use it to build an array of objects via pointer
arithmetic, but no one is doing it anymore.

3c445dacc4 pci-ids.rst: add Red Hat pci-id for RISC-V IOMMU device
The RISC-V IOMMU PCI device we're going to add next is a reference
implementation of the riscv-iommu spec [1], which predicts that the
IOMMU can be implemented as a PCIe device.

However, RISC-V International (RVI), the entity that ratified the
riscv-iommu spec, didn't bother assigning a PCI ID for this IOMMU PCIe
implementation that the spec predicts. This puts us in an uncommon
situation because we want to add the reference IOMMU PCIe implementation
but we don't have a PCI ID for it.

Given that RVI doesn't provide a PCI ID for it we reached out to Red Hat
and Gerd Hoffman, and they were kind enough to give us a PCI ID for the
RISC-V IOMMU PCI reference device.

Thanks Red Hat and Gerd for this RISC-V IOMMU PCIe device ID.

0c54acb824 hw/riscv: add RISC-V IOMMU base emulation
The RISC-V IOMMU specification is now ratified as-per the RISC-V
international process. The latest frozen specifcation can be found at:

https://github.com/riscv-non-isa/riscv-iommu/releases/download/v1.0/riscv-iommu.pdf

Add the foundation of the device emulation for RISC-V IOMMU. It includes
support for s-stage (sv32, sv39, sv48, sv57 caps) and g-stage (sv32x4,
sv39x4, sv48x4, sv57x4 caps).

Other capabilities like ATS and DBG support will be added incrementally
in the next patches.

53c1557b23 hw/char: sifive_uart: Print uart characters async
The current approach of using qemu_chr_fe_write() and ignoring the
return values results in dropped characters [1].

Let's update the SiFive UART to use a async sifive_uart_xmit() function
to transmit the characters and apply back pressure to the guest with
the SIFIVE_UART_TXFIFO_FULL status.

This should avoid dropped characters and more realisticly model the
hardware.

RV32 OpenSBI need a fw_dynamic_info parameter with 32-bit fields instead
of target_ulong.

In RV64 QEMU, target_ulong is 64. So it is not right for booting RV32 OpenSBI.
We create a fw_dynmaic_info32 struct for this purpose.

77dd098a5e hw/sd/omap_mmc: Don't use sd_cmd_type_t
In commit 1ab08790bb we did some refactoring of the SD card
implementation, which included a rearrangement of the sd_cmd_type_t
enum values.  Unfortunately we didn't notice that this enum is not
used solely inside the SD card model itself, but is also used by the
OMAP MMC controller device.  In the OMAP MMC controller, it is used
to implement the handling of the Type field of the MMC_CMD register,
so changing the enum values so that they no longer lined up with the
bit definitions for that register field broke the controller model.
The effect is that Linux fails to boot from an SD card on the "sx1"
machine.

Give omap-mmc its own enum which we can document as needing to match
the encoding used in this device's register, so it isn't sharing
sd_cmd_type_t with the SD card model any more.  We can then move
sd_cmd_type_t's definition out of sd.h and into sd.c, which is the
only place that uses it.

05d501a1ea aspeed/smc: Fix write incorrect data into flash in user mode
According to the design of ASPEED SPI controllers user mode, users write the
data to flash, the SPI drivers set the Control Register(0x10) bit 0 and 1
enter user mode. Then, SPI drivers send flash commands for writing data.
Finally, SPI drivers set the Control Register (0x10) bit 2 to stop
active control and restore bit 0 and 1.

According to the design of ASPEED SMC model, firmware writes the
Control Register and the "aspeed_smc_flash_update_ctrl" function is called.
Then, this function verify Control Register(0x10) bit 0 and 1. If it set user
mode, the value of s->snoop_index is SNOOP_START else SNOOP_OFF.
If s->snoop_index is SNOOP_START, the "aspeed_smc_do_snoop" function verify
the first incomming data is a new flash command and writes the corresponding
dummy bytes if need.

However, it did not check the current unselect status. If current unselect
status is "false" and firmware set the IO MODE by Control Register bit 31:28,
the value of s->snoop_index will be changed to SNOOP_START again and
"aspeed_smc_do_snoop" misunderstand that the incomming data is the new flash
command and it causes writing unexpected data into flash.

Example:
1. Firmware set user mode by Control Register bit 0 and 1(0x03)
2. SMC model set s->snoop SNOOP_START
3. Firmware set Quad Page Program with 4-Byte Address command (0x34)
4. SMC model verify this flash command and it needs 4 dummy bytes.
5. Firmware send 4 bytes address.
6. SMC model receives 4 bytes address
7. Firmware set QPI IO MODE by Control Register bit 31. (0x80000003)
8. SMC model verify new user mode by Control Register bit 0 and 1.
   Then, set s->snoop SNOOP_START again. (It is the wrong behavior.)
9. Firmware send 0xebd8c134 data and it should be written into flash.
   However, SMC model misunderstand that the first incoming data, 0x34,
   is the new command because the value of s->snoop is changed to SNOOP_START.
   Finally, SMC sned the incorrect data to flash model.

Introduce a new unselect attribute in AspeedSMCState to save the current
unselect status for user mode and set it "true" by default.
Update "aspeed_smc_flash_update_ctrl" function to check the previous unselect
status. If both new unselect status and previous unselect status is different,
update s->snoop_index value and call "aspeed_smc_flash_do_select".

Increase VMStateDescription version.

4c1d0af4a2 hw/misc/aspeed_hace: Fix SG Accumulative hashing
Make the Aspeed HACE module use the new qcrypto accumulative hashing functions
when in scatter-gather accumulative mode. A hash context will maintain a
"running-hash" as each scatter-gather chunk is received.

Previously each scatter-gather "chunk" was cached
so the hash could be computed once the final chunk was received.
However, the cache was a shallow copy, so once the guest overwrote the
memory provided to HACE the final hash would not be correct.

404e75343c hw/gpio/aspeed: Support different memory region ops
It set "aspeed_gpio_ops" struct which containing read and write callbacks
to be used when I/O is performed on the GPIO region.

Besides, in the previous design of ASPEED SOCs, one register is used for
setting one function for 32 GPIO pins.
ex: GPIO000 is used for setting data value for GPIO A, B, C and D in AST2600.
ex: GPIO004 is used for setting direction for GPIO A, B, C and D in AST2600.

However, the register set have a significant change in AST2700.
Each GPIO pin has their own control register. In other words, users are able to
set one GPIO pin’s direction, interrupt enable, input mask and so on
in one register. The aspeed_gpio_read/aspeed_gpio_write callback functions
are not compatible AST2700.

Introduce a new "const MemoryRegionOps *" attribute in AspeedGPIOClass and
use it in aspeed_gpio_realize function.

455e3bc3f7 s390x: Rebuild IPLB for SCSI device directly from DIAG308
Because virtio-scsi type devices use a non-architected IPLB pbt code they cannot
be set and stored normally. Instead, the IPLB must be rebuilt during re-ipl.

As s390x does not natively support multiple boot devices, the devno field is
used to store the position in the boot order for the device.

Handling the rebuild as part of DIAG308 removes the need to check the devices
for invalid IPLBs later in the IPL.

bb185de423 s390x: Add individual loadparm assignment to CCW device
Add a loadparm property to the VirtioCcwDevice object so that different
loadparms can be defined on a per-device basis for CCW boot devices.

The machine/global loadparm is still supported. If both a global and per-device
loadparm are defined, the per-device value will override the global value for
that device, but any other devices that do not specify a per-device loadparm
will still use the global loadparm.

It is invalid to assign a loadparm to a non-boot device.

f63e7089b4 tcg/riscv: Add basic support for vector
The RISC-V vector instruction set utilizes the LMUL field to group
multiple registers, enabling variable-length vector registers. This
implementation uses only the first register number of each group while
reserving the other register numbers within the group.

In TCG, each VEC_IR can have 3 types (TCG_TYPE_V64/128/256), and the
host runtime needs to adjust LMUL based on the type to use different
register groups.

This presents challenges for TCG's register allocation. Currently, we
avoid modifying the register allocation part of TCG and only expose the
minimum number of vector registers.

For example, when the host vlen is 64 bits and type is TCG_TYPE_V256, with
LMUL equal to 4, we use 4 vector registers as one register group. We can
use a maximum of 8 register groups, but the V0 register number is reserved
as a mask register, so we can effectively use at most 7 register groups.
Moreover, when type is smaller than TCG_TYPE_V256, only 7 registers are
forced to be used. This is because TCG cannot yet dynamically constrain
registers with type; likewise, when the host vlen is 128 bits and
TCG_TYPE_V256, we can use at most 15 registers.

There is not much pressure on vector register allocation in TCG now, so
using 7 registers is feasible and will not have a major impact on code
generation.

This patch:
1. Reserves vector register 0 for use as a mask register.
2. When using register groups, reserves the additional registers within
   each group.

5504a81261 KVM: Dynamic sized kvm memslots array
Zhiyi reported an infinite loop issue in VFIO use case.  The cause of that
was a separate discussion, however during that I found a regression of
dirty sync slowness when profiling.

Each KVMMemoryListerner maintains an array of kvm memslots.  Currently it's
statically allocated to be the max supported by the kernel.  However after
Linux commit 4fc096a99e ("KVM: Raise the maximum number of user memslots"),
the max supported memslots reported now grows to some number large enough
so that it may not be wise to always statically allocate with the max
reported.

What's worse, QEMU kvm code still walks all the allocated memslots entries
to do any form of lookups.  It can drastically slow down all memslot
operations because each of such loop can run over 32K times on the new
kernels.

Fix this issue by making the memslots to be allocated dynamically.

Here the initial size was set to 16 because it should cover the basic VM
usages, so that the hope is the majority VM use case may not even need to
grow at all (e.g. if one starts a VM with ./qemu-system-x86_64 by default
it'll consume 9 memslots), however not too large to waste memory.

There can also be even better way to address this, but so far this is the
simplest and should be already better even than before we grow the max
supported memslots.  For example, in the case of above issue when VFIO was
attached on a 32GB system, there are only ~10 memslots used.  So it could
be good enough as of now.

In the above VFIO context, measurement shows that the precopy dirty sync
shrinked from ~86ms to ~3ms after this patch applied.  It should also apply
to any KVM enabled VM even without VFIO.

NOTE: we don't have a FIXES tag for this patch because there's no real
commit that regressed this in QEMU. Such behavior existed for a long time,
but only start to be a problem when the kernel reports very large
nr_slots_max value.  However that's pretty common now (the kernel change
was merged in 2021) so we attached cc:stable because we'll want this change
to be backported to stable branches.
