2024-08-28Merge tag 'qcom-drivers-fixes-for-6.11' of ↵Arnd Bergmann
https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes Qualcomm driver fixes for v6.11 This corrects the tzmem virt-to-phys conversion, which caused issues for the uefisecapp implementation of EFI variable access. SDM670 is excluded from tzmem usage due to reported issues. The SCM get wait queue context call is corrected to be marked ATOMIC and some dead code in qseecom, following the tzmem conversion, is removed. The memory backing command DB is remapped writecombined, to avoid XPU violations when Linux runs without the Qualcomm hypervisor. Two compile fixes are added for pd-mapper, and the broken reference count is corrected, to make pd-mapper deal with remoteprocs going away. In pmic_glink a race condition where the client callbacks might be called before we returned the client handle is corrected. The broken conditions for when to signal that the firmware is going down is also corrected. In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the pdr callback, as this is being invoked in atomic context. Konrad's email address is updated in MAINTAINERS, and related mailmap entries are added. * tag 'qcom-drivers-fixes-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: pd-mapper: Fix singleton refcount firmware: qcom: tzmem: disable sdm670 platform soc: qcom: pmic_glink: Actually communicate when remote goes down usb: typec: ucsi: Move unregister out of atomic section soc: qcom: pmic_glink: Fix race during initialization firmware: qcom: qseecom: remove unused functions firmware: qcom: tzmem: fix virtual-to-physical address conversion firmware: qcom: scm: Mark get_wq_ctx() as atomic call MAINTAINERS: Update Konrad Dybcio's email address mailmap: Add an entry for Konrad Dybcio soc: qcom: pd-mapper: mark qcom_pdm_domains as __maybe_unused soc: qcom: cmd-db: Map shared memory as WC, not WB soc: qcom: pd-mapper: Depend on ARCH_QCOM || COMPILE_TEST Link: https://lore.kernel.org/r/20240826145209.1646159-1-andersson@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Use scope based cleanup, instead of manual of_node_put() calls, which automatically free()s "struct device_node". While at it, refactor the code from knav_queue_probe() into the separate functions to make auto cleanup look more neat.

2024-08-28soc: ti: pruss: factor out memories setupKousik Sanagavarapu
Factor out memories setup code from probe() into a new function pruss_of_setup_memories(). This sets the stage for introducing auto cleanup of the device node (done in the subsequent patch), since the clean up depends on the scope of the pointer and factoring out code into a separate function obviously limits the scope of the various variables used in that function. Apart from the above, this change also has the advantage of making the code look more neat. While at it, use dev_err_probe() instead of plain dev_err() as this new function is called by the probe().

2024-08-21soc: qcom: pd-mapper: Fix singleton refcountBjorn Andersson
The Qualcomm pd-mapper is a refcounted singleton, but the refcount is never incremented, which means the as soon as any remoteproc instance stops the count will hit 0. At this point the pd-mapper QMI service is stopped, leaving firmware without access to the PD information. Stopping any other remoteproc instances will result in a use-after-free, which best case manifest itself as a refcount underflow: refcount_t: underflow; use-after-free.

2024-08-21soc: qcom: pmic_glink: Actually communicate when remote goes downBjorn Andersson
When the pmic_glink state is UP and we either receive a protection- domain (PD) notification indicating that the PD is going down, or that the whole remoteproc is going down, it's expected that the pmic_glink client instances are notified that their function has gone DOWN. This is not what the code does, which results in the client state either not updating, or being wrong in many cases. So let's fix the conditions.

2024-08-21usb: typec: ucsi: Move unregister out of atomic sectionBjorn Andersson
Commit '9329933699b3 ("soc: qcom: pmic_glink: Make client-lock non-sleeping")' moved the pmic_glink client list under a spinlock, as it is accessed by the rpmsg/glink callback, which in turn is invoked from IRQ context. This means that ucsi_unregister() is now called from atomic context, which isn't feasible as it's expecting a sleepable context. An effort is under way to get GLINK to invoke its callbacks in a sleepable context, but until then lets schedule the unregistration. A side effect of this is that ucsi_unregister() can now happen after the remote processor, and thereby the communication link with it, is gone. pmic_glink_send() is amended with a check to avoid the resulting NULL pointer dereference. This does however result in the user being informed about this error by the following entry in the kernel log: ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5 Fixes: 9329933699b3 ("soc: qcom: pmic_glink: Make client-lock non-sleeping") Cc: stable@vger.kernel.org Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Tested-by: Amit Pundir <amit.pundir@linaro.org> Reviewed-by: Johan Hovold <johan+linaro@kernel.org> Tested-by: Johan Hovold <johan+linaro@kernel.org> Signed-off-by: Bjorn Andersson <quic_bjorande@quicinc.com> Link: https://lore.kernel.org/r/20240820-pmic-glink-v6-11-races-v3-2-eec53c750a04@quicinc.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>
2024-08-21soc: qcom: pmic_glink: Fix race during initializationBjorn Andersson
As pointed out by Stephen Boyd it is possible that during initialization of the pmic_glink child drivers, the protection-domain notifiers fires, and the associated work is scheduled, before the client registration returns and as a result the local "client" pointer has been initialized. The outcome of this is a NULL pointer dereference as the "client" pointer is blindly dereferenced. Timeline provided by Stephen: CPU0 CPU1 ---- ---- ucsi->client = NULL; devm_pmic_glink_register_client() client->pdr_notify(client->priv, pg->client_state) pmic_glink_ucsi_pdr_notify() schedule_work(&ucsi->register_work) <schedule away> pmic_glink_ucsi_register() ucsi_register() pmic_glink_ucsi_read_version() pmic_glink_ucsi_read() pmic_glink_ucsi_read() pmic_glink_send(ucsi->client) <client is NULL BAD> ucsi->client = client // Too late! This code is identical across the altmode, battery manager and usci child drivers. Resolve this by splitting the allocation of the "client" object and the registration thereof into two operations. This only happens if the protection domain registry is populated at the time of registration, which by the introduction of commit '1ebcde047c54 ("soc: qcom: add pd-mapper implementation")' became much more likely.

2024-07-30soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data membersAngeloGioacchino Del Regno
All of mutex_mod and mutex_table_mod contain an array of bit numbers, which can go from 0 to 63, it is hence not needed to use an unsigned 32-bits integer to store that: change them to unsigned 8-bits instead. As for the mutex_sof table since this directly contains the values to write to the DISP_MUTEXn_CTL register, which has only bits [13:0] (so this register is effectively 14 bits long), change that to use unsigned 16-bits. The type of mutex_{mod,sof}_reg was also changed to 16 bits, as the maximum value that those will ever have is 0x800, because it calculates as 0x30 + (0x20 * n) where n's maximum value is 63. This reduces module size and brings no functional changes.

2024-07-28soc: qcom: cmd-db: Map shared memory as WC, not WBVolodymyr Babchuk
Linux does not write into cmd-db region. This region of memory is write protected by XPU. XPU may sometime falsely detect clean cache eviction as "write" into the write protected region leading to secure interrupt which causes an endless loop somewhere in Trust Zone. The only reason it is working right now is because Qualcomm Hypervisor maps the same region as Non-Cacheable memory in Stage 2 translation tables. The issue manifests if we want to use another hypervisor (like Xen or KVM), which does not know anything about those specific mappings. Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC removes dependency on correct mappings in Stage 2 tables. This patch fixes the issue by updating the mapping to MEMREMAP_WC.

Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

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. 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" * tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (122 commits) firmware: turris-mox-rwtm: Initialize completion before mailbox firmware: turris-mox-rwtm: Fix checking return value of wait_for_completion_timeout() firmware: turris-mox-rwtm: Do not complete if there are no waiters MAINTAINERS: drop riscv list from cache controllers platform: cznic: turris-omnia-mcu: fix Kconfig dependencies bus: sunxi-rsb: Constify struct regmap_bus soc: sunxi: sram: Constify struct regmap_config platform: cznic: turris-omnia-mcu: Depend on WATCHDOG platform: cznic: turris-omnia-mcu: Depend on OF soc: samsung: exynos-pmu: add support for PMU_ALIVE non atomic registers arm64: stm32: enable scmi regulator for stm32 firmware: qcom: tzmem: blacklist more platforms for SHM Bridge soc: qcom: wcnss: simplify with cleanup.h soc: qcom: pdr: simplify with cleanup.h soc: qcom: ocmem: simplify with cleanup.h soc: qcom: mdt_loader: simplify with cleanup.h soc: qcom: llcc: simplify with cleanup.h firmware: qcom: tzmem: simplify returning pointer without cleanup soc: qcom: socinfo: Add PM6350 PMIC arm64: dts: renesas: rz-smarc: Replace fixed regulator for USB VBUS ...
