PXP (Protected Xe Path) is an i915 component, available on
GEN12 and newer platforms, that helps to establish the hardware
protected session and manage the status of the alive software session,
as well as its life cycle.
changes from v10:
- Added v10 delta into history of patches that changed in v10
- Fixed checkpatch errors.
Tested with: https://patchwork.freedesktop.org/series/87570/

This will be used for communication between the i915 driver and the mei
one. Defining it in a stand-alone patch to avoid circualr dependedencies
between the patches modifying the 2 drivers.
Split out from an original patch from Huang, Sean Z
v2: rename the component struct (Rodrigo)

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
Ahead of the PXP implementation, define the relevant define flag and
kconfig option.
v2: flip kconfig default to N. Some machines have IFWIs that do not
support PXP, so we need it to be an opt-in until we add support to query
the caps from the mei device.
v10: change comments from "Gen12+" to "Gen12 and newer"

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
The context is required to send the session termination commands to the
VCS, which will be implemented in a follow-up patch. We can also use the
presence of the context as a check of pxp initialization completion.
v2: use perma-pinned context (Chris)
v3: rename pinned_context functions (Chris)
v4: split export of pinned_context functions to a separate patch (Rodrigo)

From: "Huang, Sean Z" <sean.z.huang@intel.com>
Implement the funcs to create the TEE channel, so kernel can
send the TEE commands directly to TEE for creating the arbitrary
(default) session.
v2: fix locking, don't pollute dev_priv (Chris)
v3: wait for mei PXP component to be bound.
v4: drop the wait, as the component might be bound after i915 load
completes. We'll instead check when sending a tee message.
v5: fix an issue with mei_pxp module removal
v6: don't use fetch_and_zero in fini (Rodrigo)

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
The setting is required by hardware to allow us doing further protection
operation such as sending commands to GPU or TEE. The register needs to
be re-programmed on resume, so for simplicitly we bundle the programming
with the component binding, which is automatically called on resume.
Further HW set-up operations will be added in the same location in
follow-up patches, so get ready for them by using a couple of
init/fini_hw wrappers instead of calling the KCR funcs directly.
v3: move programming to component binding function, rework commit msg

Cc: Huang, Sean Z, Huang, Daniele Ceraolo Spurio, Chris Wilson, Rodrigo Vivi
From: "Huang, Sean Z" <sean.z.huang@intel.com>
Create the arbitrary session, with the fixed session id 0xf, after
system boot, for the case that application allocates the protected
buffer without establishing any protection session. Because the
hardware requires at least one alive session for protected buffer
creation. This arbitrary session will need to be re-created after
teardown or power event because hardware encryption key won't be
valid after such cases.
The session ID is exposed as part of the uapi so it can be used as part
of userspace commands.
v2: use gt->uncore->rpm (Chris)
v3: s/arb_is_in_play/arb_is_valid (Chris), move set-up to the new
init_hw function
v4: move interface defs to separate header, set arb_is valid to false
on fini (Rodrigo)
v5: handle async component binding

From: "Huang, Sean Z" <sean.z.huang@intel.com>
Teardown is triggered when the display topology changes and no
long meets the secure playback requirement, and hardware trashes
all the encryption keys for display. Additionally, we want to emit a
teardown operation to make sure we're clean on boot and resume
v2: emit in the ring, use high prio request (Chris)
v3: better defines, stalling flush, cleaned up and renamed submission
funcs (Chris)

thanks for catching this Harish - its a valid bug.
i should have used a stronger make option when building / testing.
since the series needs a rebase anyway (drm-tip from just now
causing issues), I will push a new rev out.

From: "Huang, Sean Z" <sean.z.huang@intel.com>
The HW will generate a teardown interrupt when session termination is
required, which requires i915 to submit a terminating batch. Once the HW
is done with the termination it will generate another interrupt, at
which point it is safe to re-create the session.
Since the termination and re-creation flow is something we want to
trigger from the driver as well, use a common work function that can be
called both from the irq handler and from the driver set-up flows, which
has the addded benefit of allowing us to skip any extra locks because
the work itself serializes the operations.
v2: use struct completion instead of bool (Chris)
v3: drop locks, clean up functions and improve comments (Chris),
move to common work function.
v4: improve comments, simplify wait logic (Rodrigo)
v5: unconditionally set interrupts, rename state_attacked var (Rodrigo)
v10: remove inclusion of intel_gt_types.h from intel_pxp.h (Jani)

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
This api allow user mode to create protected buffers and to mark
contexts as making use of such objects. Only when using contexts
marked in such a way is the execution guaranteed to work as expected.
Contexts can only be marked as using protected content at creation time
(i.e. the parameter is immutable) and they must be both bannable and not
recoverable. Given that the protected session gets invalidated on
suspend, contexts created this way hold a runtime pm wakeref until
they're either destroyed or invalidated.
All protected objects and contexts will be considered invalid when the
PXP session is destroyed and all new submissions using them will be
rejected. All intel contexts within the invalidated gem contexts will be
marked banned. Userspace can detect that an invalidation has occurred via
the RESET_STATS ioctl, where we report it the same way as a ban due to a
hang.
v5: squash patches, rebase on proto_ctx, update kerneldoc
v6: rebase on obj create_ext changes
v7: Use session counter to check if an object it valid, hold wakeref in
context, don't add a new flag to RESET_STATS (Daniel)
v8: don't increase guilty count for contexts banned during pxp
invalidation (Rodrigo)
v9: better comments, avoid wakeref put race between pxp_inval and
context_close, add usage examples (Rodrigo)
v10: modify internal set/get-protected-context functions to not
return -ENODEV when setting PXP param to false or getting param
when running on pxp-unsupported hw or getting param when i915
was built with CONFIG_PXP off

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
Now that we can handle destruction and re-creation of the arb session,
we can postpone the start of the session to the first submission that
requires it, to avoid keeping it running with no user.
v10: increase timeout when waiting in intel_pxp_start as firmware
session startup is slower right after boot.

From: "Huang, Sean Z" <sean.z.huang@intel.com>
During the power event S3+ sleep/resume, hardware will lose all the
encryption keys for every hardware session, even though the
session state might still be marked as alive after resume. Therefore,
we should consider the session as dead on suspend and invalidate all the
objects. The session will be automatically restarted on the first
protected submission on resume.
v2: runtime suspend also invalidates the keys
v3: fix return codes, simplify rpm ops (Chris), use the new worker func
v4: invalidate the objects on suspend, don't re-create the arb sesson on
resume (delayed to first submission).
v5: move irq changes back to irq patch (Rodrigo)
v6: drop invalidation in runtime suspend (Rodrigo)

From: Anshuman Gupta <anshuman.gupta@intel.com>
Add support to enable/disable PLANE_SURF Decryption Request bit.
It requires only to enable plane decryption support when following
condition met.
1. PXP session is enabled.
2. Buffer object is protected.
v2:
- Used gen fb obj user_flags instead gem_object_metadata. [Krishna]
v3:
- intel_pxp_gem_object_status() API changes.
v4: use intel_pxp_is_active (Daniele)
v5: rebase and use the new protected object status checker (Daniele)
v6: used plane state for plane_decryption to handle async flip
as suggested by Ville.
v7: check pxp session while plane decrypt state computation. [Ville]
removed pointless code. [Ville]
v8 (Daniele): update PXP check
v9: move decrypt check after icl_check_nv12_planes() when overlays
have fb set (Juston)
v10 (Daniele): update PXP check again to match rework in earlier
patches and don't consider protection valid if the object has not
been used in an execbuf beforehand.

From: Anshuman Gupta <anshuman.gupta@intel.com>
When protected sufaces has flipped and pxp session is disabled,
display black pixels by using plane color CTM correction.
v2:
- Display black pixels in async flip too.
v3:
- Removed the black pixels logic for async flip. [Ville]
- Used plane state to force black pixels. [Ville]
v4 (Daniele): update pxp_is_borked check.
v5: rebase on top of v9 plane decryption moving the decrypt check

+/**
+ * DOC: PXP
+ *
+ * PXP (Protected Xe Path) is a feature available in Gen12 and newer platforms.
+ * It allows execution and flip to display of protected (i.e. encrypted)
+ * objects. The SW support is enabled via the CONFIG_DRM_I915_PXP kconfig.
+ *
+ * Objects can opt-in to PXP encryption at creation time via the
+ * I915_GEM_CREATE_EXT_PROTECTED_CONTENT create_ext flag. For objects to be
+ * correctly protected they must be used in conjunction with a context created
+ * with the I915_CONTEXT_PARAM_PROTECTED_CONTENT flag. See the documentation
+ * of those two uapi flags for details and restrictions.
+ *
+ * Protected objects are tied to a pxp session; currently we only support one
+ * session, which i915 manages and whose index is available in the uapi
+ * (I915_PROTECTED_CONTENT_DEFAULT_SESSION) for use in instructions targeting
+ * protected objects.
+ * The session is invalidated by the HW when certain events occur (e.g.
+ * suspend/resume). When this happens, all the objects that were used with the
+ * session are marked as invalid and all contexts marked as using protected
+ * content are banned. Any further attempt at using them in an execbuf call is
+ * rejected, while flips are converted to black frames.
+ *
+ * Some of the PXP setup operations are performed by the Management Engine,
+ * which is handled by the mei driver; communication between i915 and mei is
+ * performed via the mei_pxp component module.

Note that discrete cards can support PXP as well, but we haven't tested
on those yet so keeping it disabled for now.
