Introduce a driver to query and expose detailed, per-subsystem (as opposed to the existing qcom_stats driver which exposes SoC-wide data) about low power mode states of a given RPM master. That includes the APSS (ARM), MPSS (modem) and other remote cores, depending on the platform configuration. This is a vastly cleaned up and restructured version of a similar driver found in msm-5.4.

2023-05-24soc: qcom: qmi: Use alloc_ordered_workqueue() to create ordered workqueuesTejun Heo
BACKGROUND ========== When multiple work items are queued to a workqueue, their execution order doesn't match the queueing order. They may get executed in any order and simultaneously. When fully serialized execution - one by one in the queueing order - is needed, an ordered workqueue should be used which can be created with alloc_ordered_workqueue(). However, alloc_ordered_workqueue() was a later addition. Before it, an ordered workqueue could be obtained by creating an UNBOUND workqueue with @max_active==1. This originally was an implementation side-effect which was broken by 4c16bd327c74 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered"). Because there were users that depended on the ordered execution, 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered") made workqueue allocation path to implicitly promote UNBOUND workqueues w/ @max_active==1 to ordered workqueues. While this has worked okay, overloading the UNBOUND allocation interface this way creates other issues. It's difficult to tell whether a given workqueue actually needs to be ordered and users that legitimately want a min concurrency level wq unexpectedly gets an ordered one instead. With planned UNBOUND workqueue updates to improve execution locality and more prevalence of chiplet designs which can benefit from such improvements, this isn't a state we wanna be in forever. This patch series audits all callsites that create an UNBOUND workqueue w/ @max_active==1 and converts them to alloc_ordered_workqueue() as necessary. WHAT TO LOOK FOR ================ The conversions are from alloc_workqueue(WQ_UNBOUND | flags, 1, args..) to alloc_ordered_workqueue(flags, args...) which don't cause any functional changes. If you know that fully ordered execution is not ncessary, please let me know. I'll drop the conversion and instead add a comment noting the fact to reduce confusion while conversion is in progress. If you aren't fully sure, it's completely fine to let the conversion through. The behavior will stay exactly the same and we can always reconsider later. As there are follow-up workqueue core changes, I'd really appreciate if the patch can be routed through the workqueue tree w/ your acks. Thanks.

This change updates the logic used by the mdt loader to understand whether the firmware images are split or not.

2023-04-27Merge tag 'modules-6.4-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "The summary of the changes for this pull requests is: - Song Liu's new struct module_memory replacement - Nick Alcock's MODULE_LICENSE() removal for non-modules - My cleanups and enhancements to reduce the areas where we vmalloc module memory for duplicates, and the respective debug code which proves the remaining vmalloc pressure comes from userspace. Most of the changes have been in linux-next for quite some time except the minor fixes I made to check if a module was already loaded prior to allocating the final module memory with vmalloc and the respective debug code it introduces to help clarify the issue. Although the functional change is small it is rather safe as it can only *help* reduce vmalloc space for duplicates and is confirmed to fix a bootup issue with over 400 CPUs with KASAN enabled. I don't expect stable kernels to pick up that fix as the cleanups would have also had to have been picked up. Folks on larger CPU systems with modules will want to just upgrade if vmalloc space has been an issue on bootup. Given the size of this request, here's some more elaborate details: The functional change change in this pull request is the very first patch from Song Liu which replaces the 'struct module_layout' with a new 'struct module_memory'. The old data structure tried to put together all types of supported module memory types in one data structure, the new one abstracts the differences in memory types in a module to allow each one to provide their own set of details. This paves the way in the future so we can deal with them in a cleaner way. If you look at changes they also provide a nice cleanup of how we handle these different memory areas in a module. This change has been in linux-next since before the merge window opened for v6.3 so to provide more than a full kernel cycle of testing. It's a good thing as quite a bit of fixes have been found for it. Jason Baron then made dynamic debug a first class citizen module user by using module notifier callbacks to allocate / remove module specific dynamic debug information. Nick Alcock has done quite a bit of work cross-tree to remove module license tags from things which cannot possibly be module at my request so to: a) help him with his longer term tooling goals which require a deterministic evaluation if a piece a symbol code could ever be part of a module or not. But quite recently it is has been made clear that tooling is not the only one that would benefit. Disambiguating symbols also helps efforts such as live patching, kprobes and BPF, but for other reasons and R&D on this area is active with no clear solution in sight. b) help us inch closer to the now generally accepted long term goal of automating all the MODULE_LICENSE() tags from SPDX license tags In so far as a) is concerned, although module license tags are a no-op for non-modules, tools which would want create a mapping of possible modules can only rely on the module license tag after the commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"). Nick has been working on this *for years* and AFAICT I was the only one to suggest two alternatives to this approach for tooling. The complexity in one of my suggested approaches lies in that we'd need a possible-obj-m and a could-be-module which would check if the object being built is part of any kconfig build which could ever lead to it being part of a module, and if so define a new define -DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've suggested would be to have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as well but that means getting kconfig symbol names mapping to modules always, and I don't think that's the case today. I am not aware of Nick or anyone exploring either of these options. Quite recently Josh Poimboeuf has pointed out that live patching, kprobes and BPF would benefit from resolving some part of the disambiguation as well but for other reasons. The function granularity KASLR (fgkaslr) patches were mentioned but Joe Lawrence has clarified this effort has been dropped with no clear solution in sight [1]. In the meantime removing module license tags from code which could never be modules is welcomed for both objectives mentioned above. Some developers have also welcomed these changes as it has helped clarify when a module was never possible and they forgot to clean this up, and so you'll see quite a bit of Nick's patches in other pull requests for this merge window. I just picked up the stragglers after rc3. LWN has good coverage on the motivation behind this work [2] and the typical cross-tree issues he ran into along the way. The only concrete blocker issue he ran into was that we should not remove the MODULE_LICENSE() tags from files which have no SPDX tags yet, even if they can never be modules. Nick ended up giving up on his efforts due to having to do this vetting and backlash he ran into from folks who really did *not understand* the core of the issue nor were providing any alternative / guidance. I've gone through his changes and dropped the patches which dropped the module license tags where an SPDX license tag was missing, it only consisted of 11 drivers. To see if a pull request deals with a file which lacks SPDX tags you can just use: ./scripts/spdxcheck.py -f \ $(git diff --name-only commid-id | xargs echo) You'll see a core module file in this pull request for the above, but that's not related to his changes. WE just need to add the SPDX license tag for the kernel/module/kmod.c file in the future but it demonstrates the effectiveness of the script. Most of Nick's changes were spread out through different trees, and I just picked up the slack after rc3 for the last kernel was out. Those changes have been in linux-next for over two weeks. The cleanups, debug code I added and final fix I added for modules were motivated by David Hildenbrand's report of boot failing on a systems with over 400 CPUs when KASAN was enabled due to running out of virtual memory space. Although the functional change only consists of 3 lines in the patch "module: avoid allocation if module is already present and ready", proving that this was the best we can do on the modules side took quite a bit of effort and new debug code. The initial cleanups I did on the modules side of things has been in linux-next since around rc3 of the last kernel, the actual final fix for and debug code however have only been in linux-next for about a week or so but I think it is worth getting that code in for this merge window as it does help fix / prove / evaluate the issues reported with larger number of CPUs. Userspace is not yet fixed as it is taking a bit of time for folks to understand the crux of the issue and find a proper resolution. Worst come to worst, I have a kludge-of-concept [3] of how to make kernel_read*() calls for modules unique / converge them, but I'm currently inclined to just see if userspace can fix this instead" Link: https://lore.kernel.org/all/Y/kXDqW+7d71C4wz@bombadil.infradead.org/ [0] Link: https://lkml.kernel.org/r/025f2151-ce7c-5630-9b90-98742c97ac65@redhat.com [1] Link: https://lwn.net/Articles/927569/ [2] Link: https://lkml.kernel.org/r/20230414052840.1994456-3-mcgrof@kernel.org [3] * tag 'modules-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: (121 commits) module: add debugging auto-load duplicate module support module: stats: fix invalid_mod_bytes typo module: remove use of uninitialized variable len module: fix building stats for 32-bit targets module: stats: include uapi/linux/module.h module: avoid allocation if module is already present and ready module: add debug stats to help identify memory pressure module: extract patient module check into helper modules/kmod: replace implementation with a semaphore Change DEFINE_SEMAPHORE() to take a number argument module: fix kmemleak annotations for non init ELF sections module: Ignore L0 and rename is_arm_mapping_symbol() module: Move is_arm_mapping_symbol() to module_symbol.h module: Sync code of is_arm_mapping_symbol() scripts/gdb: use mem instead of core_layout to get the module address interconnect: remove module-related code interconnect: remove MODULE_LICENSE in non-modules zswap: remove MODULE_LICENSE in non-modules zpool: remove MODULE_LICENSE in non-modules x86/mm/dump_pagetables: remove MODULE_LICENSE in non-modules ...

The probe function stores the sr_info pointer using platform_set_drvdata(). Use the corresponding platform_get_drvdata() to retrieve that pointer in the remove and shutdown functions. This simplifies these functions and makes error handling unnecessary. This is a good thing as at least for .remove() returning an error code doesn't have the desired effect.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.4 The Qualcomm SCM driver will now always clear the download bit, avoiding entering download mode on a clean reboot because the bootloader left it set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to a well defined size. SM6375 support is added, and SC8180X, QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented. GENI gains support for newer hardware with deeper FIFOs. The BWMON driver is updated to better handle the two register blocks, which are not consistent between MSM8998 and newer platforms. The LLCC driver no longer assumes a fixes stride across the various banks, and instead acquire the bank placement from DeviceTree. EDAC support for polling is introduced. EDAC support on SDM845 is disabled, as its been observed that accessing relevant registers is not permitted on most devices. PMIC GLINK is reworked to support defining which auxiliary children to spawn per platform, support for spawning a UCSI child is added and SM8450 and SM8550 is introduced. The RPM power-domain driver is cleaned up by moving and generalizing structures that are common between platforms, rather than duplicating everything. Macros are replaced with just direct definition of the relevant structures. Support for defining parent relationships between the power-domains is introduced, like it has been in rpmhpd for a long time. Number of processors has gone up, so max processor count in SMEM is bumped again. Error handling in SMSM is cleaned up using dev_err_probe(). Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150, SA8775P and a number of PMICs. * tag 'qcom-drivers-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (51 commits) dt-bindings: firmware: document Qualcomm SC8180X SCM dt-bindings: sram: qcom,imem: document SM6375 IMEM soc: qcom: icc-bwmon: Handle global registers correctly soc: qcom: icc-bwmon: Remove unused struct member soc: qcom: smsm: Use dev_err_probe() firmware: qcom_scm: Add SM6375 compatible soc: qcom: llcc: Add configuration data for SM7150 dt-bindings: arm: msm: Add LLCC for SM7150 dt-bindings: soc: qcom: smd-rpm: re-add missing qcom,rpm-msm8994 soc: qcom: pmic_glink: register ucsi aux device dt-bindings: soc: qcom: qcom,pmic-glink: document SM8550 compatible dt-bindings: soc: qcom: qcom,pmic-glink: document SM8450 compatible firmware: qcom_scm: Clear download bit during reboot dt-bindings: soc: qcom: aoss: Document QDU1000/QRU1000 compatible dt-bindings: firmware: qcom,scm: Update QDU1000/QRU1000 compatible dt-bindings: soc: qcom: smd-rpm: Add IPQ9574 compatible firmware: qcom_scm: Use fixed width src vm bitmap dt-bindings: firmware: qcom,scm: document IPQ5332 SCM dt-bindings: scm: Add compatible for IPQ9574 soc: qcom: rpmpd: Remove useless comments ...

https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers RISC-V SoC drivers for v6.4 Microchip: Mailbox controller & client changes for the system controller on PolarFire SoC. The controller bits have been acked by Jassi. Primarily the changes work around a "hardware" bug (really the system controller's software, but it may as well be hardware as customers cannot change it) where interrupts are not generated if a service fails. The mailbox controller driver is tweaked to use polling, rather than interrupt, mode and there are some changes to timeout code required in the client driver as a result. There's some opportunistic cleanup that I performed while doing the swap too. Canaan: A single fix for some randconfig issues that crop up when !mmu is enabled for 32-bit kernels, due to my changes in a previous release that swapped out select based entablement of the driver.

2023-04-13soc/tegra: cbb: remove MODULE_LICENSE in non-modulesNick Alcock
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.
