2024-07-28soc: qcom: cmd-db: Map shared memory as WC, not WBVolodymyr Babchuk1-1/+1
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. I tested this on SA8155P with Xen.

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. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...

2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman1-2/+2
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

When using /proc/interrupts to collect statistics on smp2p interrupt counts, it is hard to distinguish the different instances of smp2p from each other. For example to debug a processor boot issue, the ready and handover interrupts are checked for sanity to ensure the firmware reached a specific initialization stage. Remove "smp2p" string from the irq request so that the irq will default to the device name. Add an .irq_print_chip() callback to print the irq chip name as the device name. These two changes allow for a unique name to be used in /proc/interrupts as shown below. / # cat /proc/interrupts | grep smp2p 18: ... ipcc 196610 Edge smp2p-adsp 20: ... ipcc 131074 Edge smp2p-modem 170: ... smp2p-modem 1 Edge q6v5 ready 178: ... smp2p-adsp 1 Edge q6v5 ready Signed-off-by: Chris Lew <quic_clew@quicinc.com> Reviewed-by: Konrad Dybcio <konrad.dybcio@linaro.org> Link: https://lore.kernel.org/r/20240627104831.4176799-2-quic_sudeepgo@quicinc.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>

2024-06-24soc: qcom: add pd-mapper implementationDmitry Baryshkov5-0/+737
Existing userspace protection domain mapper implementation has several issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't reread JSON files if firmware location is changed (or if firmware was not available at the time pd-mapper was started but the corresponding directory is mounted later), etc. Provide in-kernel service implementing protection domain mapping required to work with several services, which are provided by the DSP firmware. This module is loaded automatically by the remoteproc drivers when necessary via the symbol dependency. It uses a root node to match a protection domains map for a particular board. It is not possible to implement it as a 'driver' as there is no corresponding device.

2024-06-21soc: qcom: smem: Add a feature code getterKonrad Dybcio1-0/+33
Recent (SM8550+ ish) Qualcomm SoCs have a new mechanism for precisely identifying the specific SKU and the precise speed bin (in the general meaning of this word, anyway): a pair of values called Product Code and Feature Code. Based on this information, we can deduce the available frequencies for things such as Adreno. In the case of Adreno specifically, Pcode is useless for non-prototype SoCs. Introduce a getter for the feature code and export it.

Until SM8450, there was only one broadcast region (Broadcast_OR) used to broadcast write and check for status bit 0. >From SM8450 onwards another broadcast region (Broadcast_AND) has been added which checks for status bit 1. This hasn't been updated and Broadcast_OR region was wrongly being used to check for status bit 1 all along. Hence define new regmap structure for Broadcast_AND region and initialize this regmap when HW block version is greater than 4.1, otherwise initialize as a NULL pointer for backwards compatibility. Switch from broadcast_OR to broadcast_AND region (when defined in DT) for checking status bit 1 as Broadcast_OR region checks only for bit 0.
