https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers A few more Qualcomm driver updates for v6.10 This fixes a sleep-while-atomic issue in pmic_glink, stemming from the fact that the GLINK callback comes from interrupt context. It fixes the Bluetooth address in the example of qcom,wcnss, and it enables UEFI variables on SC8180X devices (Primus and Flex 5G). * tag 'qcom-drivers-for-6.10-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: firmware: qcom: uefisecapp: Allow on sc8180x Primus and Flex 5G soc: qcom: pmic_glink: Make client-lock non-sleeping dt-bindings: soc: qcom,wcnss: fix bluetooth address example Link: https://lore.kernel.org/r/20240508020900.204413-1-andersson@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers RISC-V SoC Kconfig Updates for v6.10 A few different bits of SoC-related Kconfig work. The first part of this is shared with the DT updates - the modification of all SOC_CANAAN users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away from the k230 that is able to be used in a "common" kernel. The other thing here is the removal of most of the SOC_VENDOR options, with their ARCH_VENDOR equivalents that've been waiting in the wings for 1 year+ now made visible. Due a lapse on my part when originally adding the ARCH_VENDOR stuff, the Microchip transition isn't complete - the _POLARFIRE was a mistake to keep as there's gonna be non-PolarFire RISC-V stuff from Microchip soonTM.

The recently introduced commit '635ce0db8956 ("soc: qcom: pmic_glink: don't traverse clients list without a lock")' ensured that the clients list is not modified while traversed. But the callback is made from the GLINK IRQ handler and as such this mutual exclusion can not be provided by a (sleepable) mutex. Replace the mutex with a spinlock.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. * tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (21 commits) soc: qcom: cmd-db: replace deprecated strncpy with strtomem soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request firmware: qcom: scm: Modify only the download bits in TCSR register firmware: qcom: scm: Fix __scm and waitq completion variable initialization firmware: qcom: scm: Rework dload mode availability check firmware: qcom: scm: Remove redundant scm argument from qcom_scm_waitq_wakeup() firmware: qcom: scm: Remove log reporting memory allocation failure soc: qcom: pmic_glink: notify clients about the current state soc: qcom: pmic_glink: don't traverse clients list without a lock soc: qcom: mention intentionally broken module autoloading firmware: qcom: qcm: fix unused qcom_scm_qseecom_allowlist MAINTAINERS: Split Qualcomm SoC and linux-arm-msm entries soc: qcom: qcom_stats: Add DSPs and apss subsystem stats dt-bindings: soc: qcom: qcom,pmic-glink: document QCM6490 compatible soc: qcom: socinfo: Add SMB2360 PMIC soc: qcom: socinfo: Add X1E80100 SoC ID table entry dt-bindings: arm: qcom,ids: Add SoC ID for X1E80100 soc: qcom: Update init level to core_initcall() for cmd-db and rpmh-rsc soc: qcom: icc-bwmon: Convert to use maple tree register cache firmware: qcom_scm: remove IS_ERR() checks from qcom_scm_bw_{en,dis}able() ...

However, it could result on degraded performance, so the fact that it's missing should still be alerted.

Add cmdq_pkt_acquire_event() function to support CMDQ user making an instruction for acquiring event. CMDQ users can use cmdq_pkt_acquire_event() as `mutex_lock` and cmdq_pkt_clear_event() as `mutex_unlock` to protect the global resource modified instructions between them. cmdq_pkt_acquire_event() would wait for event to be cleared. After event is cleared by cmdq_pkt_clear_event() in other GCE threads, cmdq_pkt_acquire_event() would set event and keep executing next instruction. So the mutex would work like this: cmdq_pkt_acquire_event() /* mutex lock */ /* critical secton instructions that modified global resource */ cmdq_pkt_clear_event() /* mutex unlock */ Prevent the critical section instructions from being affected by other GCE threads.

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned addresses associated with it. These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.

2024-04-08soc: samsung: exynos-asv: Update Energy Model after adjusting voltageLukasz Luba
When the voltage for OPPs is adjusted there is a need to also update Energy Model framework. The EM data contains power values which depend on voltage values. The EM structure is used for thermal (IPA governor) and in scheduler task placement (EAS) so it should reflect the real HW model as best as possible to operate properly. Based on data on Exynos5422 ASV tables the maximum power difference might be ~29%. An Odroid-XU4 (with a random sample SoC in this chip lottery) showed power difference for some OPPs ~20%. Therefore, it's worth to update the EM.

Since SOC_FOO should be deprecated from patch [1], and cleanup for other SoCs is already in the mailing list [2,3,4], we remove the use of SOC_CANAAN and use ARCH_CANAAN for SoCs vendored by Canaan instead from now on. Thus, we should also change the Makefile here to use ARCH_CANAAN. Then, since we have introduced SOC_CANAAN_K210 for K210-specific drivers, we should replace its drivers depends on SOC_CANAAN_K210 and default select when it has the symbol SOC_CANAAN_K210.
