https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.7 This introduces partial support for the Qualcomm Secure Execution Environment SCM interface, and uses this to implement EFI variable access on the Windows On Snapdragon devices (for now). The 32/64-bit calling convention detector of the SCM interface is updated to not choose 64-bit convention when Linux is 32-bit. The "extern" specifier is dropped from the interface include file. The LLCC driver gains support for carrying configuration for multiple different system/DDR configurations for a given platform, and selecting between them. Support for Q[DR]U1000 is added to the driver. All exported symbols are transitioned to EXPORT_SYMBOL_GPL(). The platform_drivers in the Qualcomm SoC are transitioned to the void-returning remove_new implementation. The rmtfs memory driver gains support for leaving guard pages around the used area, to avoid issues if the allocation happens to be placed adjacent to another protected memory region. The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and various PMICs used together with SM8550. * tag 'qcom-drivers-for-6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (44 commits) soc: qcom: socinfo: Convert to platform remove callback returning void soc: qcom: smsm: Convert to platform remove callback returning void soc: qcom: smp2p: Convert to platform remove callback returning void soc: qcom: smem: Convert to platform remove callback returning void soc: qcom: rmtfs_mem: Convert to platform remove callback returning void soc: qcom: qcom_stats: Convert to platform remove callback returning void soc: qcom: qcom_gsbi: Convert to platform remove callback returning void soc: qcom: qcom_aoss: Convert to platform remove callback returning void soc: qcom: pmic_glink: Convert to platform remove callback returning void soc: qcom: ocmem: Convert to platform remove callback returning void soc: qcom: llcc-qcom: Convert to platform remove callback returning void soc: qcom: icc-bwmon: Convert to platform remove callback returning void firmware: qcom_scm: use 64-bit calling convention only when client is 64-bit soc: qcom: llcc: Handle a second device without data corruption soc: qcom: Switch to EXPORT_SYMBOL_GPL() soc: qcom: smem: Annotate struct qcom_smem with __counted_by soc: qcom: rmtfs: Support discarding guard pages dt-bindings: reserved-memory: rmtfs: Allow guard pages dt-bindings: firmware: qcom,scm: document IPQ5018 compatible firmware: qcom_scm: disable SDI if required ...

2023-10-16soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size()Gustavo A. R. Silva
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). While there, use struct_size() helper, instead of the open-coded version, to calculate the size for the allocation of the whole flexible structure, including of course, the flexible-array member. This code was found with the help of Coccinelle, and audited and fixed manually. Signed-off-by: "Gustavo A. R.

Other drivers (i915, amdgpu) use DRM_MODE_CONNECTOR_DisplayPort even if the DP stream is handled by the USB-C altmode. While we are still working on implementing the proper way to let userspace know that the DP is wrapped into USB-C, change connector type to be DRM_MODE_CONNECTOR_DisplayPort.

Consolidation of PCC shared memory region command and status bitfields definitions that were duplicated and scattered across multiple PCC client drivers (Sudeep Holla)." * tag 'acpi-pcc-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: soc: kunpeng_hccs: Migrate to use generic PCC shmem related macros hwmon: (xgene) Migrate to use generic PCC shmem related macros i2c: xgene-slimpro: Migrate to use generic PCC shmem related macros ACPI: PCC: Add PCC shared memory region command and status bitfields mailbox: pcc: Support shared interrupt for multiple subspaces mailbox: pcc: Add support for platform notification handling
2023-10-05soc: renesas: Make ARCH_R9A07G043 (riscv version) depend on NONPORTABLEJisheng Zhang
Drew found "CONFIG_DMA_GLOBAL_POOL=y causes ADMA buffer alloc to fail" the log looks like: mmc0: Unable to allocate ADMA buffers - falling back to standard DMA The logic is: generic riscv defconfig selects ARCH_RENESAS then ARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes all non-dma-coherent riscv platforms have a dma global pool, this assumption seems not correct. And I believe DMA_GLOBAL_POOL should not be selected by ARCH_SOCFAMILIY, instead, only ARCH under some specific conditions can select it globaly, for example NOMMU ARM and so on, because it's designed for special cases such as "nommu cases where non-cacheable memory lives in a fixed place in the physical address map" as pointed out by Robin. Fix the issue by making ARCH_R9A07G043 (riscv version) depend on NONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 by default. And even for random config case, there will be less debug effort once we see NONPORTABLE is enabled.
