2024-12-02platform/x86: asus-nb-wmi: Ignore unknown event 0xCFArmin Wolf
On the Asus X541UAK an unknown event 0xCF is emited when the charger is plugged in. This is caused by the following AML code: If (ACPS ()) { ACPF = One Local0 = 0x58 If (ATKP) { ^^^^ATKD.IANE (0xCF) } } Else { ACPF = Zero Local0 = 0x57 } Notify (AC0, 0x80) // Status Change If (ATKP) { ^^^^ATKD.IANE (Local0) } Sleep (0x64) PNOT () Sleep (0x0A) NBAT (0x80) Ignore the 0xCF event to silence the unknown event warning.

2024-12-02of: Add #address-cells/#size-cells in the device-tree root empty nodeHerve Codina
On systems where ACPI is enabled or when a device-tree is not passed to the kernel by the bootloader, a device-tree root empty node is created. This device-tree root empty node does not have the #address-cells and the #size-cells properties This leads to the use of the default address cells and size cells values which are defined in the code to 1 for the address cells value and 1 for the size cells value. According to the devicetree specification and the OpenFirmware standard (IEEE 1275-1994) the default value for #address-cells should be 2. Also, according to the devicetree specification, the #address-cells and the #size-cells are required properties in the root node. The device tree compiler already uses 2 as default value for address cells and 1 for size cells. The powerpc PROM code also uses 2 as default value for address cells and 1 for size cells. Modern implementation should have the #address-cells and the #size-cells properties set and should not rely on default values. On x86, this root empty node is used and the code default values are used. In preparation of the support for device-tree overlay on PCI devices feature on x86 (i.e. the creation of the PCI root bus device-tree node), the default value for #address-cells needs to be updated. Indeed, on x86_64, addresses are on 64bits and the upper part of an address is needed for correct address translations. On x86_32 having the default value updated does not lead to issues while the upper part of a 64-bit value is zero. Changing the default value for all architectures may break device-tree compatibility. Indeed, existing dts file without the #address-cells property set in the root node will not be compatible with this modification. Instead of updating default values, add both required #address-cells and #size-cells properties in the device-tree empty node. Use 2 for both properties value in order to fully support 64-bit addresses and sizes on systems using this empty root node.

2024-12-02mmc: core: Further prevent card detect during shutdownUlf Hansson
Disabling card detect from the host's ->shutdown_pre() callback turned out to not be the complete solution. More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev() is called, which adds a devres reference to the regmap, to be able to retrieve a dev's regmap by name using dev_get_regmap(). When calling regmap_exit, the opposite does not happen, and the reference is kept until the dev is detached. Add a regmap_detach_dev() function and call it in regmap_exit() to make sure that the devres reference is not kept.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Commit 2f4f9fe5bf5f ("bnxt_en: Support adding ntuple rules on RSS contexts") added support for redirecting to an RSS context as an ntuple rule action. However, it forgot to update the ETHTOOL_GRXCLSRULE codepath. This caused `ethtool -n` to always report the action as "Action: Direct to queue 0" which is wrong. Fix by teaching bnxt driver to report the RSS context when applicable.

2024-11-30PCI/pwrctrl: Unregister platform device only if one actually existsBrian Norris
If a PCI device has an associated device_node with power supplies, pci_bus_add_device() creates platform devices for use by pwrctrl. When the PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to locate the related platform device, then unregisters it. But when we remove a PCI device with no associated device node, dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the first device with "dev->of_node == NULL". The result is that we (a) mistakenly unregister a completely unrelated platform device, leading to issues like the first trace below, and (b) dereference the NULL pointer from dev_of_node() when clearing OF_POPULATED, as in the second trace. Unregister a platform device only if there is one associated with this PCI device. This resolves issues seen when doing: # echo 1 > /sys/bus/pci/devices/.../remove Sample issue from unregistering the wrong platform device: WARNING: CPU: 0 PID: 5095 at drivers/regulator/core.c:5885 regulator_unregister+0x140/0x160 Call trace: regulator_unregister+0x140/0x160 devm_rdev_release+0x1c/0x30 release_nodes+0x68/0x100 devres_release_all+0x98/0xf8 device_unbind_cleanup+0x20/0x70 device_release_driver_internal+0x1f4/0x240 device_release_driver+0x20/0x40 bus_remove_device+0xd8/0x170 device_del+0x154/0x380 device_unregister+0x28/0x88 of_device_unregister+0x1c/0x30 pci_stop_bus_device+0x154/0x1b0 pci_stop_and_remove_bus_device_locked+0x28/0x48 remove_store+0xa0/0xb8 dev_attr_store+0x20/0x40 sysfs_kf_write+0x4c/0x68 Later NULL pointer dereference for of_node_clear_flag(NULL, OF_POPULATED): Unable to handle kernel NULL pointer dereference at virtual address 00000000000000c0 Call trace: pci_stop_bus_device+0x190/0x1b0 pci_stop_and_remove_bus_device_locked+0x28/0x48 remove_store+0xa0/0xb8 dev_attr_store+0x20/0x40 sysfs_kf_write+0x4c/0x68 Link: https://lore.kernel.org/r/20241126210443.4052876-1-briannorris@chromium.org Fixes: 681725afb6b9 ("PCI/pwrctl: Remove pwrctl device without iterating over all children of pwrctl parent") Reported-by: Saurabh Sengar <ssengar@linux.microsoft.com> Closes: https://lore.kernel.org/r/1732890621-19656-1-git-send-email-ssengar@linux.microsoft.com Signed-off-by: Brian Norris <briannorris@chromium.org> [bhelgaas: commit log] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2024-11-29net: enetc: Do not configure preemptible TCs if SIs do not supportWei Fang
Both ENETC PF and VF drivers share enetc_setup_tc_mqprio() to configure MQPRIO. And enetc_setup_tc_mqprio() calls enetc_change_preemptible_tcs() to configure preemptible TCs. However, only PF is able to configure preemptible TCs. Because only PF has related registers, while VF does not have these registers. So for VF, its hw->port pointer is NULL. Therefore, VF will access an invalid pointer when accessing a non-existent register, which will cause a crash issue. The simplified log is as follows. root@ls1028ardb:~# tc qdisc add dev eno0vf0 parent root handle 100: \ mqprio num_tc 4 map 0 0 1 1 2 2 3 3 queues 1@0 1@1 1@2 1@3 hw 1 [ 187.290775] Unable to handle kernel paging request at virtual address 0000000000001f00 [ 187.424831] pc : enetc_mm_commit_preemptible_tcs+0x1c4/0x400 [ 187.430518] lr : enetc_mm_commit_preemptible_tcs+0x30c/0x400 [ 187.511140] Call trace: [ 187.513588] enetc_mm_commit_preemptible_tcs+0x1c4/0x400 [ 187.518918] enetc_setup_tc_mqprio+0x180/0x214 [ 187.523374] enetc_vf_setup_tc+0x1c/0x30 [ 187.527306] mqprio_enable_offload+0x144/0x178 [ 187.531766] mqprio_init+0x3ec/0x668 [ 187.535351] qdisc_create+0x15c/0x488 [ 187.539023] tc_modify_qdisc+0x398/0x73c [ 187.542958] rtnetlink_rcv_msg+0x128/0x378 [ 187.547064] netlink_rcv_skb+0x60/0x130 [ 187.550910] rtnetlink_rcv+0x18/0x24 [ 187.554492] netlink_unicast+0x300/0x36c [ 187.558425] netlink_sendmsg+0x1a8/0x420 [ 187.606759] ---[ end trace 0000000000000000 ]--- In addition, some PFs also do not support configuring preemptible TCs, such as eno1 and eno3 on LS1028A.

2024-11-29net: enetc: read TSN capabilities from port register, not SIVladimir Oltean
Configuring TSN (Qbv, Qbu, PSFP) capabilities requires access to port registers, which are available to the PSI but not the VSI. Yet, the SI port capability register 0 (PSICAPR0), exposed to both PSIs and VSIs, presents the same capabilities to the VF as to the PF, thus leading the VF driver into thinking it can configure these features. In the case of ENETC_SI_F_QBU, having it set in the VF leads to a crash: root@ls1028ardb:~# tc qdisc add dev eno0vf0 parent root handle 100: \ mqprio num_tc 4 map 0 0 1 1 2 2 3 3 queues 1@0 1@1 1@2 1@3 hw 1 [ 187.290775] Unable to handle kernel paging request at virtual address 0000000000001f00 [ 187.424831] pc : enetc_mm_commit_preemptible_tcs+0x1c4/0x400 [ 187.430518] lr : enetc_mm_commit_preemptible_tcs+0x30c/0x400 [ 187.511140] Call trace: [ 187.513588] enetc_mm_commit_preemptible_tcs+0x1c4/0x400 [ 187.518918] enetc_setup_tc_mqprio+0x180/0x214 [ 187.523374] enetc_vf_setup_tc+0x1c/0x30 [ 187.527306] mqprio_enable_offload+0x144/0x178 [ 187.531766] mqprio_init+0x3ec/0x668 [ 187.535351] qdisc_create+0x15c/0x488 [ 187.539023] tc_modify_qdisc+0x398/0x73c [ 187.542958] rtnetlink_rcv_msg+0x128/0x378 [ 187.547064] netlink_rcv_skb+0x60/0x130 [ 187.550910] rtnetlink_rcv+0x18/0x24 [ 187.554492] netlink_unicast+0x300/0x36c [ 187.558425] netlink_sendmsg+0x1a8/0x420 [ 187.606759] ---[ end trace 0000000000000000 ]--- while the other TSN features in the VF are harmless, because the net_device_ops used for the VF driver do not expose entry points for these other features. These capability bits are in the process of being defeatured from the SI registers. We should read them from the port capability register, where they are also present, and which is naturally only exposed to the PF. The change to blame (relevant for stable backports) is the one where this started being a problem, aka when the kernel started to crash due to the wrong capability seen by the VF driver.
