Pull EFI updates from Ard Biesheuvel:
"Note the removal of the EFI fake memory map support - this is believed
to be unused and no longer worth supporting. However, we could easily
bring it back if needed.
With recent developments regarding confidential VMs and unaccepted
memory, combined with kexec, creating a known inaccurate view of the
firmware's memory map and handing it to the OS is a feature we can
live without, hence the removal. Alternatively, I could imagine making
this feature mutually exclusive with those confidential VM related
features, but let's try simply removing it first.
Summary:
- Drop support for the 'fake' EFI memory map on x86
- Add an SMBIOS based tweak to the EFI stub instructing the firmware
on x86 Macbook Pros to keep both GPUs enabled
- Replace 0-sized array with flexible array in EFI memory attributes
table handling
- Drop redundant BSS clearing when booting via the native PE
entrypoint on x86
- Avoid returning EFI_SUCCESS when aborting on an out-of-memory
condition
- Cosmetic tweak for arm64 KASLR loading logic"

Pull SoC dt updates from Arnd Bergmann:
"The devicetree updates are fairly well spread out across platforms,
with Qualcomm making up about a third of the total.
There are three new SoCs in existing product families this:
- NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores
instead of just two as well as a GPU and more high-speed I/O
devices.
- Qualcomm QCS8550 is a variant of SM8550 for IOT devices
- Airoha EN7581 is a 10G-PON network chip and related to the MT7981
Wireless router chip from its parent Mediatek.
In total there are 58 new machines, including four riscv boards and
eight for 32-bit arm.
The most exciting new addition is probably a pair of laptops based on
the Qualcomm x1e80100 (Snapdragon X1 Elite) chip, the Asus Vivobook
S15 and the Lenovo Yoga Slim7x.
Other noteworthy new additions are:
- A total of 20 Qualcomm based machines, mostly Android devices from
Samsung, Motorola and LG, as well as a wireless router and some
reference designs
- Six NXP i.MX based machines, mostly industrial boards along with
some reference designs
- Mediatek sees some interesting Filogic based routers including the
"OpenWRT One", a few new Chromebooks as well as single-board
computers.
- Four machines from Solidrun based on Marvell cn913x, replacing the
older Armada 8000 based counterparts
- The four Amlogic machines are all set top boxes or reference
designs for them
- The nine new Rockchips machines are mostly single-board computers
including some interesting ones based on the rk3588 chip like the
ROCK 5 ITX board and the CM3588 with its four NVMe slots
- The RISC-V boards are all single-board computers based on Starfive
JH7110, Microchip MPFS and Allwinner D1, which all had similar
boards already
There are also a lot of updates to already supported machines, notably
for the TI K3, Rockchips, Freescale and of course Qualcomm platforms"

Introduces kvm_x86_call(), to streamline the usage of static calls of
kvm_x86_ops. The current implementation of these calls is verbose and
could lead to alignment challenges. This makes the code susceptible to
exceeding the "80 columns per single line of code" limit as defined in
the coding-style document. Another issue with the existing implementation
is that the addition of kvm_x86_ prefix to hooks at the static_call sites
hinders code readability and navigation. kvm_x86_call() is added to
improve code readability and maintainability, while adhering to the coding
style guidelines.

The use of static_call_cond() is essentially the same as static_call() on
x86 (e.g. static_call() now handles a NULL pointer as a NOP), so replace
it with static_call() to simplify the code.

The GHCB 2.0 specification defines 2 GHCB request types to allow SNP guests
to send encrypted messages/requests to firmware: SNP Guest Requests and SNP
Extended Guest Requests. These encrypted messages are used for things like
servicing attestation requests issued by the guest. Implementing support for
these is required to be fully GHCB-compliant.
For the most part, KVM only needs to handle forwarding these requests to
firmware (to be issued via the SNP_GUEST_REQUEST firmware command defined
in the SEV-SNP Firmware ABI), and then forwarding the encrypted response to
the guest.
However, in the case of SNP Extended Guest Requests, the host is also
able to provide the certificate data corresponding to the endorsement key
used by firmware to sign attestation report requests. This certificate data
is provided by userspace because:
1) It allows for different keys/key types to be used for each particular
guest with requiring any sort of KVM API to configure the certificate
table in advance on a per-guest basis.
2) It provides additional flexibility with how attestation requests might
be handled during live migration where the certificate data for
source/dest might be different.
3) It allows all synchronization between certificates and firmware/signing
key updates to be handled purely by userspace rather than requiring
some in-kernel mechanism to facilitate it. [1]
To support fetching certificate data from userspace, a new KVM exit type will
be needed to handle fetching the certificate from userspace. An attempt to
define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this
was introduced in v1 of this patchset, but is still being discussed by
community, so for now this patchset only implements a stub version of SNP
Extended Guest Requests that does not provide certificate data, but is still
enough to provide compliance with the GHCB 2.0 spec.
|
|
Version 2 of GHCB specification added support for the SNP Extended Guest
Request Message NAE event. This event serves a nearly identical purpose
to the previously-added SNP_GUEST_REQUEST event, but for certain message
types it allows the guest to supply a buffer to be used for additional
information in some cases.
Currently the GHCB spec only defines extended handling of this sort in
the case of attestation requests, where the additional buffer is used to
supply a table of certificate data corresponding to the attestion
report's signing key. Support for this extended handling will require
additional KVM APIs to handle coordinating with userspace.
Whether or not the hypervisor opts to provide this certificate data is
optional. However, support for processing SNP_EXTENDED_GUEST_REQUEST
GHCB requests is required by the GHCB 2.0 specification for SNP guests,
so for now implement a stub implementation that provides an empty
certificate table to the guest if it supplies an additional buffer, but
otherwise behaves identically to SNP_GUEST_REQUEST.

sev_guest.h currently contains various definitions relating to the
format of SNP_GUEST_REQUEST commands to SNP firmware. Currently only the
sev-guest driver makes use of them, but when the KVM side of this is
implemented there's a need to parse the SNP_GUEST_REQUEST header to
determine whether additional information needs to be provided to the
guest. Prepare for this by moving those definitions to a common header
that's shared by host/guest code so that KVM can also make use of them.

Version 2 of GHCB specification added support for the SNP Guest Request
Message NAE event. The event allows for an SEV-SNP guest to make
requests to the SEV-SNP firmware through the hypervisor using the
SNP_GUEST_REQUEST API defined in the SEV-SNP firmware specification.
This is used by guests primarily to request attestation reports from
firmware. There are other request types are available as well, but the
specifics of what guest requests are being made generally does not
affect how they are handled by the hypervisor, which only serves as a
proxy for the guest requests and firmware responses.
Implement handling for these events.
When an SNP Guest Request is issued, the guest will provide its own
request/response pages, which could in theory be passed along directly
to firmware. However, these pages would need special care:
- Both pages are from shared guest memory, so they need to be
protected from migration/etc. occurring while firmware reads/writes
to them. At a minimum, this requires elevating the ref counts and
potentially needing an explicit pinning of the memory. This places
additional restrictions on what type of memory backends userspace
can use for shared guest memory since there would be some reliance
on using refcounted pages.
- The response page needs to be switched to Firmware-owned state
before the firmware can write to it, which can lead to potential
host RMP #PFs if the guest is misbehaved and hands the host a
guest page that KVM is writing to for other reasons (e.g. virtio
buffers).
Both of these issues can be avoided completely by using
separately-allocated bounce pages for both the request/response pages
and passing those to firmware instead. So that's the approach taken
here.

Explicitly suppress userspace emulated MMIO exits that are triggered when
emulating a task switch as KVM doesn't support userspace MMIO during
complex (multi-step) emulation. Silently ignoring the exit request can
result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to
userspace for some other reason prior to purging mmio_needed.
See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write exits if
emulator detects exception") for more details on KVM's limitations with
respect to emulated MMIO during complex emulator flows.

Bug the VM instead of simply warning if KVM tries to split a SPTE that is
non-present or not-huge. KVM is guaranteed to end up in a broken state as
the callers fully expect a valid SPTE, e.g. the shadow MMU will add an
rmap entry, and all MMUs will account the expected small page. Returning
'0' is also technically wrong now that SHADOW_NONPRESENT_VALUE exists,
i.e. would cause KVM to create a potential #VE SPTE.
While it would be possible to have the callers gracefully handle failure,
doing so would provide no practical value as the scenario really should be
impossible, while the error handling would add a non-trivial amount of
noise.

Merge cpufreq changes for 6.11-rc1:
- Add Loongson-3 CPUFreq driver support (Huacai Chen).
- Add support for the Arrow Lake and Lunar Lake platforms and
the out-of-band (OOB) mode on Emerald Rapids to the intel_pstate
cpufreq driver, make it support the highest performance change
interrupt and clean it up (Srinivas Pandruvada).
- Switch cpufreq to new Intel CPU model defines (Tony Luck).
- Simplify the cpufreq driver interface by switching the .exit() driver
callback to the void return data type (Lizhe, Viresh Kumar).
- Make cpufreq_boost_enabled() return bool (Dhruva Gole).
- Add fast CPPC support to the amd-pstate cpufreq driver, address
multiple assorted issues in it and clean it up (Perry Yuan, Mario
Limonciello, Dhananjay Ugwekar, Meng Li, Xiaojian Du).
- Add Allwinner H700 speed bin to the sun50i cpufreq driver (Ryan
Walklin).
- Fix memory leaks and of_node_put() usage in the sun50i and qcom-nvmem
cpufreq drivers (Javier Carrasco).
- Clean up the sti and dt-platdev cpufreq drivers (Jeff Johnson,
Raphael Gallais-Pou).
- Fix deferred probe handling in the TI cpufreq driver and wrong return
values of ti_opp_supply_probe(), and add OPP tables for the AM62Ax and
AM62Px SoCs to it (Bryan Brattlof, Primoz Fiser).
- Avoid overflow of target_freq in .fast_switch() in the SCMI cpufreq
driver (Jagadeesh Kona).
- Use dev_err_probe() in every error path in probe in the Mediatek
cpufreq driver (Nícolas Prado).
- Fix kernel-doc param for longhaul_setstate in the longhaul cpufreq
driver (Yang Li).
