optee: ffa: fix sleep in atomic context
The OP-TEE driver registers the function notif_callback() for FF-A
notifications. However, this function is called in an atomic context
leading to errors like this when processing asynchronous notifications:

tee: optee: Fix supplicant wait loop
OP-TEE supplicant is a user-space daemon and it's possible for it
be hung or crashed or killed in the middle of processing an OP-TEE
RPC call. It becomes more complicated when there is incorrect shutdown
ordering of the supplicant process vs the OP-TEE client application which
can eventually lead to system hang-up waiting for the closure of the
client application.
Allow the client process waiting in kernel for supplicant response to
be killed rather than indefinitely waiting in an unkillable state. Also,
a normal uninterruptible wait should not have resulted in the hung-task
watchdog getting triggered, but the endless loop would.
This fixes issues observed during system reboot/shutdown when supplicant
got hung for some reason or gets crashed/killed which lead to client
getting hung in an unkillable state. It in turn lead to system being in
hung up state requiring hard power off/on to recover.

Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

optee: add RPMB dependency
Prevent build error when CONFIG_RPMB=m and CONFIG_OPTEE=y by adding a
dependency to CONFIG_RPMB for CONFIG_OPTEE so the RPMB subsystem always
is reachable if configured. This means that CONFIG_OPTEE automatically
becomes compiled as a module if CONFIG_RPMB is compiled as a module. If
CONFIG_RPMB isn't configured or is configured as built-in, CONFIG_OPTEE
will remain unchanged.

optee: probe RPMB device using RPMB subsystem
Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and use an RPMB device via the RPMB subsystem instead of passing the RPMB frames via tee-supplicant in user space. A fallback mechanism is kept to route RPMB frames via tee-supplicant if the RPMB subsystem isn't available. The OP-TEE RPC ABI is extended to support iterating over all RPMB devices until one is found with the expected RPMB key already programmed.

soc: driver updates for 6.11
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are farily small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaVTTUACgkQYKtH/8kJ UiegixAAqGfwUtwk2GGZJlEGjUjT4cqrwCTLhNlaNfgN/dZxjk1XBTKvtp2mVDi2 lJN8TNqa0Csw8XZYPgHi0s1ppmwQl07Unpbc9tUeS4tAeIuputDe+ia0UtQx3Mkd GTAKJO6VzLeCnDxB4757OURZO9wYlPdZycQbnSKDyfBIapFuZwozmbAc7BuFGvBv 2Zt5lca531EJuM5wg25f+F/8XSxZIqjMA6/PTGNCYig1bx5AM2tCWK2xN+BL+dxn YVLuRZT7lSgpwivg9OHzJ49g9WeJB7RArnSDg1Ac7sNfC8476UC17BAH4rF7QSTP q2GBP2VOdRJA9mJkavtLhE/1LPDJuYTM+nt1xq7jzG2MKN7yLjX0LMrMgKsk0pXZ T2qQh7+4MA9lwlpGEwDruMajTJahbMgiAUcSivLsr18LrifAnKVHBDTRmRwNiRX2 T3/zk90kenJX1NOkc4SrdLd5iCyq0oSN+fukdh3UMgJLnAzaWOe5mKAMF7eefeog rMH276W8JwbbmIC4R2aQm6TL7IWBtaCaHuLqYOiTjooir31OgwW4Mztd7okU4v4I rOGhV0zJTSVXT+a4O2jOooWppS9xE45/F2DSigSvZjEiahZ0L4feaOrHui5PVVlW wmFmobCq6Y0Mjspdk64O1tbUWJ17CmRK1WDrUUk0VgmLy9gn6A8= =ChcR -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware.

TEE driver for Trusted Services
This introduces a TEE driver for Trusted Services [1]. Trusted Services is a TrustedFirmware.org project that provides a framework for developing and deploying device Root of Trust services in FF-A [2] Secure Partitions. The project hosts the reference implementation of Arm Platform Security Architecture [3] for Arm A-profile devices. The FF-A Secure Partitions are accessible through the FF-A driver in Linux.

tee: optee: smc: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to

- Speaking of translations, more of those for Spanish and Chinese.

optee: ffa_abi: add asynchronous notifications
Adds support for asynchronous notifications from OP-TEE in secure world when communicating via FF-A. In principle from OP-TEE and kernel driver point of view this works in the same way as for the SMC ABI based implementation. The OP-TEE FF-A ABI is expanded in OPTEE_FFA_EXCHANGE_CAPABILITIES with the capability OPTEE_FFA_SEC_CAP_ASYNC_NOTIF to indicate that OP-TEE supports asynchronous notifications. OPTEE_FFA_ENABLE_ASYNC_NOTIF is also added to tell that the driver has successfully initialized these notifications. Notification capability is negotiated while the driver is initialized. If both sides supports these notifications then they are enabled. The notification concept in this driver is merged with the FF-A concept, the lower 64 values are reserved for FF-A as asynchronous notifications while the synchronous notifications use the higher values. So a FF-A notification has to be allocated for each discrete asynchronous notification value needed. Only one asynchronous notification value is used at the moment, the "do bottom half" notification.

tee: optee: support tracking system threads
Adds support in the OP-TEE driver to keep track of reserved system threads. The logic allows one OP-TEE thread to be reserved to TEE system sessions. The optee_cq_*() functions are updated to handle this if enabled, that is when TEE describes how many thread context it supports and when at least 1 session has registered as a system session (using tee_client_system_session()). For sake of simplicity, initialization of call queue management is factorized into new helper function optee_cq_init(). The SMC ABI part of the driver enables this tracking, but the FF-A ABI part does not.

tee: optee: Fix supplicant based device enumeration
Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:
[ 73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024
Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:
$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
then echo $(basename "$dev") > $dev/driver/unbind; fi done

This works in conjunction with a feature added to Trusted Firmware for ARMv8 and above architectures that supports this.

optee: add per cpu asynchronous notification
Implements use of per-cpu irq for optee asynchronous notification. Existing optee async notif implementation allows OP-TEE world to raise an interrupt on which Linux optee driver will query some pending events. This change allows the signaling interrupt to be a per-cpu interrupt as with Arm GIC PPIs. Using a PPI instead of an SPI is useful when no GIC lines are provisioned in the chip design and there are spare PPI lines.

SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
reworks and support for variants of the existing SoC. While this remains
Arm centric for the most part, the branch now also contains updates to
risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants
(MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
soc ID, rpmh, rpm, spm and powerdomain drivers.
- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines
- A new SoC identification driver for the loongson-2 (loongarch)
platform
- memory controller updates for stm32, tegra, and renesas.
- a new DT binding to better describe LPDDR2/3/4/5 chips in
the memory controller subsystem
- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification
- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
TI, Mediatek and Marvell SoC drivers

tee: optee: fix possible memory leak in optee_register_device()
If device_register() returns error in optee_register_device(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and optee_device is freed in optee_release_device().

firmware: arm_ffa: Split up ffa_ops into info, message and memory operations
In preparation to make memory operations accessible for a non ffa_driver/device, it is better to split the ffa_ops into different categories of operations: info, message and memory. The info and memory are ffa_device independent and can be used without any associated ffa_device from a non ffa_driver. However, we don't export these info and memory APIs yet without the user. The first users of these APIs can export them.

firmware: arm_ffa: Rename ffa_dev_ops as ffa_ops
Except the message APIs, all other APIs are ffa_device independent and can be used without any associated ffa_device from a non ffa_driver. In order to reflect the same, just rename ffa_dev_ops as ffa_ops to avoid any confusion or to keep it simple.
