When there are multiple Video Ports, and only one of them is working
(for example, VP1 is working while VP0 is not), in this case, the
win_mask of VP0 is 0. However, we have already set the port mux for VP0
according to vp0->nlayers, and at the same time, in the OVL_LAYER_SEL
register, there are windows will also be assigned to layers which will
map to the inactive VPs. In this situation, vp0->win_mask is zero as it
now working, it is more reliable to calculate the used layers based on
the configuration of the OVL_LAYER_SEL register.
Note: as the configuration of OVL_LAYER_SEL is take effect when the
vsync is come, so we use the value backup in vop2->old_layer_sel instead
of read OVL_LAYER_SEL directly.

A PCIe device function interface assigned to a TVM is a TEE Device
Interface (TDI). A TDI instantiated by pci_tsm_bind() needs additional
steps taken by the TVM to be accepted into the TVM's Trusted Compute
Boundary (TCB) and transitioned to the RUN state.
pci_tsm_guest_req() is a channel for the guest to request TDISP collateral,
like Device Interface Reports, and effect TDISP state changes, like
LOCKED->RUN transititions. Similar to IDE establishment and pci_tsm_bind(),
these are long running operations involving SPDM message passing via the
DOE mailbox.
The path for a TVM to invoke pci_tsm_guest_req() is:
* TSM triggers exit via guest-to-host-interface ABI (implementation specific)
* VMM invokes handler (KVM handle_exit() -> userspace io)
* handler issues request (userspace io handler -> ioctl() ->
pci_tsm_guest_req())
* handler supplies response
* VMM posts response, notifies/re-enters TVM
This path is purely a transport for messages from TVM to platform TSM. By
design the host kernel does not and must not care about the content of
these messages. I.e. the host kernel is not in the TCB of the TVM.
As this is an opaque passthrough interface, similar to fwctl, the kernel
requires that implementations stay within the bounds defined by 'enum
pci_tsm_req_scope'. Violation of those expectations likely has market and
regulatory consequences. Out of scope requests are blocked by default.

After a PCIe device has established a secure link and session between a TEE
Security Manager (TSM) and its local Device Security Manager (DSM), the
device or its subfunctions are candidates to be bound to a private memory
context, a TVM. A PCIe device function interface assigned to a TVM is a TEE
Device Interface (TDI).
The pci_tsm_bind() requests the low-level TSM driver to associate the
device with private MMIO and private IOMMU context resources of a given TVM
represented by a @kvm argument. A device in the bound state corresponds to
the TDISP protocol LOCKED state and awaits validation by the TVM. It is a
'struct pci_tsm_link_ops' operation because, similar to IDE establishment,
it involves host side resource establishment and context setup on behalf of
the guest. It is also expected to be performed lazily to allow for
operation of the device in non-confidential "shared" context for pre-lock
configuration.

The PCIe spec defines two types of streams - selective and link. Each
stream has an ID from the same bucket so a stream ID does not tell the
type. The spec defines an "enable" bit for every stream and required
stream IDs to be unique among all enabled stream but there is no such
requirement for disabled streams.
However, when IDE_KM is programming keys, an IDE-capable device needs
to know the type of stream being programmed to write it directly to
the hardware as keys are relatively large, possibly many of them and
devices often struggle with keeping around rather big data not being
used.
Walk through all streams on a device and initialise the IDs to some
unique number, both link and selective.
The weakest part of this proposal is the host bridge ide_stream_ids_ida.
Technically, a Stream ID only needs to be unique within a given partner
pair. However, with "anonymous" / unassigned streams there is no convenient
place to track the available ids. Proceed with an ida in the host bridge
for now, but consider moving this tracking to be an ide_stream_ids_ida per
device.

The address ranges for downstream Address Association Registers need to
cover memory addresses for all functions (PFs/VFs/downstream devices)
managed by a Device Security Manager (DSM). The proposed solution is get
the memory (32-bit only) range and prefetchable-memory (64-bit capable)
range from the immediate ancestor downstream port (either the direct-attach
RP or deepest switch port when switch attached).
Similar to RID association, address associations will be set by default if
hardware sets 'Number of Address Association Register Blocks' in the
'Selective IDE Stream Capability Register' to a non-zero value. TSM drivers
can opt-out of the settings by zero'ing out unwanted / unsupported address
ranges. E.g. TDX Connect only supports prefetachable (64-bit capable)
memory ranges for the Address Association setting.
If the immediate downstream port provides both a memory range and
prefetchable-memory range, but the IDE partner port only provides 1 Address
Association Register block then the TSM driver can pick which range to
associate, or let the PCI core prioritize memory.
Note, the Address Association Register setup for upstream requests is still
uncertain so is not included.

Stop relying on phy_set_bus_width() based workaround to setup the TMDS
character rate and, instead, use the recently introduced HDMI PHY
configuration API. This is also a prerequisite to enable high color
depth and FRL support.
Additionally, move the logic to ->atomic_check() callback where the
current mode rate is already provided by the connector state. As a
matter of fact this is actually necessary to ensure the link rate is
configured before VOP2 attempts to use the PHY PLL as a DCLK source in
vop2_crtc_atomic_enable(). The rationale is to restrict any changes of
the PHY rate via CCF and, instead, prefer the PHY configuration API for
this purpose.

When making use of the HDMI PHY PLL as a VOP2 DCLK source, it's output
rate does normally match the mode clock. But this is only applicable
for default color depth of 8 bpc. For higher depths, the output clock
is further divided by the hardware according to the formula:
output rate = PHY PLL rate * 8 / bpc
Hence there is no need for VOP2 to compensate for bpc when adjusting
DCLK, but it is required to do so when computing its maximum operating
frequency.
Take color depth into consideration before deciding to switch DCLK
source.

There are a few places where log level is not checked before calling
"verbose()". This forces programs working only at
BPF_LOG_LEVEL_STATS (e.g. veristat) to allocate unnecessarily large
log buffers. Add missing checks.

The current kernel doesn't handle unpopulated cgroups any special
regarding reclaim protection. Furthermore, this wasn't a case even when
this was introduced in
bf8d5d52ff ("memcg: introduce memory.min")
Drop the incorrect documentation. (Implementation taking into account
the inner-node constraint may be added later.)
