2024-06-03gpio: tqmx86: introduce shadow register for GPIO output valueMatthias Schiffer
The TQMx86 GPIO controller uses the same register address for input and output data. Reading the register will always return current inputs rather than the previously set outputs (regardless of the current direction setting). Therefore, using a RMW pattern does not make sense when setting output values. Instead, the previously set output register value needs to be stored as a shadow register. As there is no reliable way to get the current output values from the hardware, also initialize all channels to 0, to ensure that stored and actual output values match. This should usually not have any effect in practise, as the TQMx86 UEFI sets all outputs to 0 during boot. Also prepare for extension of the driver to more than 8 GPIOs by using DECLARE_BITMAP.

2024-06-03irqchip/sifive-plic: Chain to parent IRQ after handlers are readySamuel Holland
Now that the PLIC uses a platform driver, the driver is probed later in the boot process, where interrupts from peripherals might already be pending. As a result, plic_handle_irq() may be called as early as the call to irq_set_chained_handler() completes. But this call happens before the per-context handler is completely set up, so there is a window where plic_handle_irq() can see incomplete per-context state and crash. Avoid this by delaying the call to irq_set_chained_handler() until all handlers from all PLICs are initialized.

2024-06-03platform/x86: dell-smbios: Fix wrong token data in sysfsArmin Wolf
When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong. This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.

2024-06-03Input: silead - Always support 10 fingersHans de Goede
When support for Silead touchscreens was orginal added some touchscreens with older firmware versions only supported 5 fingers and this was made the default requiring the setting of a "silead,max-fingers=10" uint32 device-property for all touchscreen models which do support 10 fingers. There are very few models with the old 5 finger fw, so in practice the setting of the "silead,max-fingers=10" is boilerplate which needs to be copy and pasted to every touchscreen config. Reporting that 10 fingers are supported on devices which only support 5 fingers doesn't cause any problems for userspace in practice, since at max 4 finger gestures are supported anyways. Drop the max_fingers configuration and simply always assume 10 fingers.

Currently kernel entry in head.S is in DMW address range, firmware is instructed to jump to this address after loading the kernel image. However kernel should not make any assumption on firmware's DMW setting, thus the entry point should be a physical address falls into direct translation region.

No documentation or commit history hinted about why SRCU has been preferred in original design, so it has been assumed to be safe to do this conversion. Unfortunately, some static analyzers raised warnings, confirmed by runtime checker, not long after the merge. At least three different issues arose when switching to RCU: - wilc_wlan_txq_filter_dup_tcp_ack is executed in a RCU read critical section yet calls wait_for_completion_timeout - wilc_wfi_init_mon_interface calls kmalloc and register_netdevice while manipulating a vif retrieved from vif list - set_channel sends command to chip (and so, also waits for a completion) while holding a vif retrieved from vif list (so, in RCU read critical section) Some of those issues are not trivial to fix and would need bigger driver rework.

2024-05-31nvme-fabrics: use reserved tag for reg read/write commandChunguang Xu
In some scenarios, if too many commands are issued by nvme command in the same time by user tasks, this may exhaust all tags of admin_q. If a reset (nvme reset or IO timeout) occurs before these commands finish, reconnect routine may fail to update nvme regs due to insufficient tags, which will cause kernel hang forever. In order to workaround this issue, maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved tags. This maybe safe for nvmf: 1. For the disable ctrl path, we will not issue connect command 2. For the enable ctrl / fw activate path, since connect and reg_xx() are called serially. So the reserved tags may still be enough while reg_xx() use reserved tags.

2024-05-31scsi: mpt3sas: Avoid possible run-time warning with long manufacturer stringsKees Cook
The prior strscpy() replacement of strncpy() here expected the manufacture_reply strings to be NUL-terminated, but it is possible they are not, as the code pattern here shows, e.g., edev->vendor_id being exactly 1 character larger than manufacture_reply->vendor_id, and the replaced strncpy() was copying only up to the size of the source character array. Replace this with memtostr(), which is the unambiguous way to convert a maybe not-NUL-terminated character array into a NUL-terminated string.

Commit 7627a0edef54 ("ata: ahci: Drop low power policy board type") dropped the board_ahci_low_power board type, and instead enables LPM if: -The AHCI controller reports that it supports LPM (Partial/Slumber), and -CONFIG_SATA_MOBILE_LPM_POLICY != 0, and -The port is not defined as external in the per port PxCMD register, and -The port is not defined as hotplug capable in the per port PxCMD register. Partial and Slumber LPM states can either be initiated by HIPM or DIPM. For HIPM (host initiated power management) to get enabled, both the AHCI controller and the drive have to report that they support HIPM. For DIPM (device initiated power management) to get enabled, only the drive has to report that it supports DIPM. However, the HBA will reject device requests to enter LPM states which the HBA does not support. The problem is that Apacer AS340 drives do not handle low power modes correctly. The problem was most likely not seen before because no one had used this drive with a AHCI controller with LPM enabled. Add a quirk so that we do not enable LPM for this drive, since we see command timeouts if we do (even though the drive claims to support DIPM).

2024-05-30of: property: Fix fw_devlink handling of interrupt-mapMarc Zyngier
Commit d976c6f4b32c ("of: property: Add fw_devlink support for interrupt-map property") tried to do what it says on the tin, but failed on a couple of points: - it confuses bytes and cells. Not a huge deal, except when it comes to pointer arithmetic - it doesn't really handle anything but interrupt-maps that have their parent #address-cells set to 0 The combinations of the two leads to some serious fun on my M1 box, with plenty of WARN-ON() firing all over the shop, and amusing values being generated for interrupt specifiers. Having 2 versions of parsing code for "interrupt-map" was a bad idea. Now that the common parsing parts have been refactored into of_irq_parse_imap_parent(), rework the code here to use it instead and fix the pointer arithmetic. Note that the dependency will be a bit different than the original code when the interrupt-map points to another interrupt-map. In this case, the original code would resolve to the final interrupt controller. Now the dependency is the parent interrupt-map (which itself should have a dependency to the parent). It is possible that a node with an interrupt-map has no driver.
