[PATCH v9 0/4] clk: qcom: Add support for multiple power-domains for a clock controller.

by Bryan O'Donoghue

Changes in v9: - Added patch to unwind pm subdomains in reverse order. It would also be possible to squash this patch into patch#2 but, my own preference is for more granular patches like this instead of "slipping in" functional changes in larger patches like #2. - bod - Unwinding pm subdomain on error in patch #2. To facilitate this change patch #1 was created - Vlad - Drops Bjorn's RB on patch #2. There is a small churn in this patch but enough that a reviewer might reasonably expect RB to be given again. - Amends commit log for patch #3 further. v8 added a lot to the commit log to provide further information but, it is clear from the comments I received on the commit log that the added verbiage was occlusive not elucidative. Reduce down the commit log of patch #3 - especially Q&A item #1. Sometimes less is more. - Link to v8: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v8: - Picks up change I agreed with Vlad but failed to cherry-pick into my b4 tree - Vlad/Bod - Rewords the commit log for patch #3. As I read it I decided I might translate bits of it from thought-stream into English - Bod - Link to v7: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v7: - Expand commit log in patch #3 I've discussed with Bjorn on IRC and video what to put into the log here and captured most of what we discussed. Mostly the point here is voting for voltages in the power-domain list is up to the drivers to do with performance states/opp-tables not for the GDSC code. - Bjorn/Bryan - Link to v6: https://lore.kernel.org/r/20241129-b4-linux-next-24-11-18-clock-multiple-po… Changes in v6: - Passes NULL to second parameter of devm_pm_domain_attach_list - Vlad - Link to v5: https://lore.kernel.org/r/20241128-b4-linux-next-24-11-18-clock-multiple-po… Changes in v5: - In-lines devm_pm_domain_attach_list() in probe() directly - Vlad - Link to v4: https://lore.kernel.org/r/20241127-b4-linux-next-24-11-18-clock-multiple-po… v4: - Adds Bjorn's RB to first patch - Bjorn - Drops the 'd' in "and int" - Bjorn - Amends commit log of patch 3 to capture a number of open questions - Bjorn - Link to v3: https://lore.kernel.org/r/20241126-b4-linux-next-24-11-18-clock-multiple-po… v3: - Fixes commit log "per which" - Bryan - Link to v2: https://lore.kernel.org/r/20241125-b4-linux-next-24-11-18-clock-multiple-po… v2: The main change in this version is Bjorn's pointing out that pm_runtime_* inside of the gdsc_enable/gdsc_disable path would be recursive and cause a lockdep splat. Dmitry alluded to this too. Bjorn pointed to stuff being done lower in the gdsc_register() routine that might be a starting point. I iterated around that idea and came up with patch #3. When a gdsc has no parent and the pd_list is non-NULL then attach that orphan GDSC to the clock controller power-domain list. Existing subdomain code in gdsc_register() will connect the parent GDSCs in the clock-controller to the clock-controller subdomain, the new code here does that same job for a list of power-domains the clock controller depends on. To Dmitry's point about MMCX and MCX dependencies for the registers inside of the clock controller, I have switched off all references in a test dtsi and confirmed that accessing the clock-controller regs themselves isn't required. On the second point I also verified my test branch with lockdep on which was a concern with the pm_domain version of this solution but I wanted to cover it anyway with the new approach for completeness sake. Here's the item-by-item list of changes: - Adds a patch to capture pm_genpd_add_subdomain() result code - Bryan - Changes changelog of second patch to remove singleton and generally to make the commit log easier to understand - Bjorn - Uses demv_pm_domain_attach_list - Vlad - Changes error check to if (ret < 0 && ret != -EEXIST) - Vlad - Retains passing &pd_data instead of NULL - because NULL doesn't do the same thing - Bryan/Vlad - Retains standalone function qcom_cc_pds_attach() because the pd_data enumeration looks neater in a standalone function - Bryan/Vlad - Drops pm_runtime in favour of gdsc_add_subdomain_list() for each power-domain in the pd_list. The pd_list will be whatever is pointed to by power-domains = <> in the dtsi - Bjorn - Link to v1: https://lore.kernel.org/r/20241118-b4-linux-next-24-11-18-clock-multiple-po… v1: On x1e80100 and it's SKUs the Camera Clock Controller - CAMCC has multiple power-domains which power it. Usually with a single power-domain the core platform code will automatically switch on the singleton power-domain for you. If you have multiple power-domains for a device, in this case the clock controller, you need to switch those power-domains on/off yourself. The clock controllers can also contain Global Distributed Switch Controllers - GDSCs which themselves can be referenced from dtsi nodes ultimately triggering a gdsc_en() in drivers/clk/qcom/gdsc.c. As an example: cci0: cci@ac4a000 { power-domains = <&camcc TITAN_TOP_GDSC>; }; This series adds the support to attach a power-domain list to the clock-controllers and the GDSCs those controllers provide so that in the case of the above example gdsc_toggle_logic() will trigger the power-domain list with pm_runtime_resume_and_get() and pm_runtime_put_sync() respectively.

zram: Regression in at least linux-6.1.y tree

by Kenneth Van Alstyne

Greetings and apologies if this isn't the proper process for reporting an issue in a LTS kernel per https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html. Happy to follow another process if more appropriate. Kernel 6.1.122 introduced a regression via commit ac3b5366b9b7c9d97b606532ceab43d2329a22f3 (backport of upstream commit 74363ec674cb172d8856de25776c8f3103f05e2f) in drivers/block/zram/zram_drv.c where attempting to set the size of /dev/zram0 after loading the zram kernel module results in a kernel NULL pointer dereference. That patch removed the following block from zram_reset_device(): - if (!init_done(zram)) { - up_write(&zram->init_lock); - return; - } However, without that, zram_reset_device subsequently calls zcomp_destroy on a device that has not been initialized, leading to the OOPS.

Its filename is mm-hugetlb-fix-avoid_reserve-to-allow-taking-folio-from-subpool.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Peter Xu <peterx(a)redhat.com> Subject: mm/hugetlb: fix avoid_reserve to allow taking folio from subpool Date: Tue, 7 Jan 2025 15:39:56 -0500 Patch series "mm/hugetlb: Refactor hugetlb allocation resv accounting", v2. This is a follow up on Ackerley's series here as replacement: https://lore.kernel.org/r/cover.1728684491.git.ackerleytng@google.com The goal of this series is to cleanup hugetlb resv accounting, especially during folio allocation, to decouple a few things: - Hugetlb folios v.s. Hugetlbfs: IOW, the hope is in the future hugetlb folios can be allocated completely without hugetlbfs. - Decouple VMA v.s. hugetlb folio allocations: allocating a hugetlb folio should not always require a hugetlbfs VMA. For example, either it got allocated from the inode level (see hugetlbfs_fallocate() where it used a pesudo VMA for allocation), or it can be allocated by other kernel subsystems. It paves way for other users to allocate hugetlb folios out of either system reservations, or subpools (instead of hugetlbfs, as a file system). For longer term, this prepares hugetlb as a separate concept versus hugetlbfs, so that hugetlb folios can be allocated by not only hugetlbfs and other things. Tests I've done: - I had a reproducer in patch 1 for the bug I found, this will start to work after patch 1 or the whole set applied. - Hugetlb regression tests (on x86_64 2MBs), includes: - All vmtests on hugetlbfs - libhugetlbfs test suite (which may fail some tests, but no new failures will be introduced by this series, so all such failures happen before this series so shouldn't be relevant). This patch (of 7): Since commit 04f2cbe35699 ("hugetlb: guarantee that COW faults for a process that called mmap(MAP_PRIVATE) on hugetlbfs will succeed"), avoid_reserve was introduced for a special case of CoW on hugetlb private mappings, and only if the owner VMA is trying to allocate yet another hugetlb folio that is not reserved within the private vma reserved map. Later on, in commit d85f69b0b533 ("mm/hugetlb: alloc_huge_page handle areas hole punched by fallocate"), alloc_huge_page() enforced to not consume any global reservation as long as avoid_reserve=true. This operation doesn't look correct, because even if it will enforce the allocation to not use global reservation at all, it will still try to take one reservation from the spool (if the subpool existed). Then since the spool reserved pages take from global reservation, it'll also take one reservation globally. Logically it can cause global reservation to go wrong. I wrote a reproducer below, trigger this special path, and every run of such program will cause global reservation count to increment by one, until it hits the number of free pages: #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h> #include <fcntl.h> #include <errno.h> #include <unistd.h> #include <stdlib.h> #include <sys/mman.h> #define MSIZE (2UL << 20) int main(int argc, char *argv[]) { const char *path; int *buf; int fd, ret; pid_t child; if (argc < 2) { printf("usage: %s <hugetlb_file>\n", argv[0]); return -1; } path = argv[1]; fd = open(path, O_RDWR | O_CREAT, 0666); if (fd < 0) { perror("open failed"); return -1; } ret = fallocate(fd, 0, 0, MSIZE); if (ret != 0) { perror("fallocate"); return -1; } buf = mmap(NULL, MSIZE, PROT_READ|PROT_WRITE, MAP_PRIVATE, fd, 0); if (buf == MAP_FAILED) { perror("mmap() failed"); return -1; } /* Allocate a page */ *buf = 1; child = fork(); if (child == 0) { /* child doesn't need to do anything */ exit(0); } /* Trigger CoW from owner */ *buf = 2; munmap(buf, MSIZE); close(fd); unlink(path); return 0; } It can only reproduce with a sub-mount when there're reserved pages on the spool, like: # sysctl vm.nr_hugepages=128 # mkdir ./hugetlb-pool # mount -t hugetlbfs -o min_size=8M,pagesize=2M none ./hugetlb-pool Then run the reproducer on the mountpoint: # ./reproducer ./hugetlb-pool/test Fix it by taking the reservation from spool if available. In general, avoid_reserve is IMHO more about "avoid vma resv map", not spool's. I copied stable, however I have no intention for backporting if it's not a clean cherry-pick, because private hugetlb mapping, and then fork() on top is too rare to hit.

[PATCH v2] PCI: fix reference leak in pci_alloc_child_bus()

by Ma Ke

When device_register(&child->dev) failed, calling put_device() to explicitly release child->dev. Otherwise, it could cause double free problem. device_register() includes device_add(). As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH] clk: qcom: gcc-x1e80100: Do not turn off usb_2 controller GDSC

by Abel Vesa

Allowing the usb_2 controller GDSC to be turned off during system suspend renders the controller unable to resume. So use PWRSTS_RET_ON instead in order to make sure this the GDSC doesn't go down.

[PATCH] arm64: dts: qcom: x1e80100: Fix usb_2 controller interrupts

by Abel Vesa

Back when the CRD support was brought up, the usb_2 controller didn't have anything connected to it in order to test it properly, so it was never enabled. On the Lenovo ThinkPad T14s, the usb_2 controller has the fingerprint controller connected to it. So enabling it, proved that the interrupts lines were wrong from the start. Fix both the pwr_event and the DWC ctrl_irq lines, according to documentation.
