2 daysInput: gscps2 - drop busy-wait and manual interrupt pump on transmitDmitry Torokhov
In gscps2_writeb_output(), after writing data to GSC_XMTDATA, the driver explicitly executed mdelay(6) and manually called gscps2_interrupt() as a polling mechanism to accelerate command responses (such as keyboard ACK or LED updates). On PA-RISC, the PS/2 controller asserts a level interrupt to the system ASIC whenever received data arrives in hardware, and the input/serio subsystem handles command responses asynchronously via completions. Busy-waiting for 6 ms on every transmitted byte introduces significant unnecessary latency during multi-byte command sequences and complicates interrupt handler locking. Remove mdelay(6) and the manual invocation of gscps2_interrupt() from gscps2_writeb_output(), relying on normal hardware interrupt delivery.

2 daysInput: gscps2 - serialize concurrent interrupt handlersDmitry Torokhov
gscps2_interrupt() may be invoked concurrently from a hardware interrupt on one CPU and from process context via gscps2_writeb_output() on another CPU. In gscps2_report_data(), ps2port->lock is released before calling serio_interrupt() to avoid recursive deadlocks. However, if two execution contexts run gscps2_report_data() concurrently for the same port, they could race to acquire serio->lock inside serio_interrupt(), potentially delivering multi-byte scancodes out of order. Serialize execution of gscps2_interrupt() using gscps2_interrupt_lock with ACQUIRE(spinlock_irqsave_try). Using spin_trylock prevents overlapping executions and guarantees in-order packet delivery without risking recursive deadlocks if an input driver synchronously sends a command back via serio_write(). If the lock cannot be acquired, return IRQ_NONE to preserve spurious interrupt detection on shared IRQ lines.

2 daysInput: gscps2 - return IRQ_NONE when interrupt is not handledDmitry Torokhov
gscps2_interrupt() is registered with IRQF_SHARED. Unconditionally returning IRQ_HANDLED when no data was pending on any GSC PS/2 port masks unhandled interrupts on the shared interrupt line and prevents the kernel core spurious interrupt detector from identifying runaway interrupt storms. Have gscps2_read_data() return whether any bytes were read, accumulate the handled status in gscps2_interrupt(), and return IRQ_RETVAL(handled).

2 daysInput: gscps2 - serialize hardware and buffer access in gscps2_flush()Dmitry Torokhov
gscps2_flush() reads from hardware registers and resets the ring buffer indices ps2port->act and ps2port->append. In gscps2_enable(), the trailing gscps2_flush() was called without holding ps2port->lock, racing with concurrent hardware interrupts and buffer access. Assert that ps2port->lock is held in gscps2_flush() with lockdep_assert_held(), and ensure all callers acquire ps2port->lock so that multi-step hardware sequences remain fully serialized without unprotected windows.

2 daysInput: gscps2 - protect buffer access in read and report helpersDmitry Torokhov
In gscps2_report_data(), the ring buffer consumer index ps2port->act was read and updated locklessly. When gscps2_interrupt() was called from process context (such as during port write or open) concurrently with a hardware interrupt running on another CPU, two execution contexts could execute gscps2_report_data() simultaneously for the same port, racing on ps2port->act and leading to duplicate, skipped, or out-of-order bytes. Protect buffer access by taking ps2port->lock inside gscps2_read_data() and gscps2_report_data(). In gscps2_report_data(), acquire ps2port->lock only when popping entries from the ring buffer and release it before calling serio_interrupt() to avoid recursive deadlocks if the input driver synchronously sends a command back via serio_write().

2 daysInput: gscps2 - use RCU for ps2port_list and manage it in open/closeDmitry Torokhov
Managing ps2port_list in gscps2_probe() and gscps2_remove() had two issues: - in gscps2_remove(), serio_unregister_port() frees the serio port, but because the port remained in ps2port_list until later in remove, a shared interrupt firing on another CPU could traverse ps2port_list and dereference the freed serio port - ps2port_list additions and deletions in probe/remove raced locklessly against list traversals in gscps2_interrupt(). Convert ps2port_list traversal in gscps2_interrupt() to use RCU, and move list management to gscps2_open() and gscps2_close(). When serio_unregister_port() runs during device removal, serio_close() is invoked, cleanly taking the port out of ps2port_list before the serio structure is destroyed, while maintaining active hardware communication during child driver disconnect.

9 daysInput: hp_sdc - shut down kicker timer on module exitRunyu Xiao
hp_sdc_kicker() rearms hp_sdc.kicker with mod_timer() after scheduling the tasklet. The module exit path uses timer_delete_sync(). That waits for a callback already running but can still leave the timer rearmed. A callback can therefore leave the timer pending while hp_sdc_exit() tears down the driver, allowing timer activity to access dismantled driver state. Use timer_shutdown_sync() for final teardown. It waits for a running callback and prevents rearming after module exit begins.

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

2026-08-05Input: gscps2 - supply PA-RISC keyboard keymap via device propertyDmitry Torokhov
Instead of hardcoding PA-RISC specific keycode tables into atkbd via compile-time inclusion, have the gscps2 PS/2 port driver attach a linux,keymap software node device property to the serio device when a keyboard port is registered. This allows atkbd to dynamically fetch and apply the custom keymap when probing the port using generic firmware property helpers, removing architecture-specific hacks from generic keyboard driver code. Co-locate the keymap definitions with the serio port driver by moving hpps2atkbd.h from drivers/input/keyboard/ to drivers/input/serio/. To handle the five conflicting keys on RDI PrecisionBook laptops without runtime model string checks or duplicate keymap tables in memory, add CONFIG_SERIO_GSCPS2_RDI_KEYCODES to drivers/input/serio/Kconfig and resolve the conflicting keycodes at compile time via preprocessor macros.

Commit 44f920069911 ("Input: gscps2 - use guard notation when acquiring spinlock") moved the receive loop into gscps2_read_data() and gscps2_report_data(). While moving the code, it preserved the writes to buffer[ps2port->append], but omitted the following producer index update from the original loop: ps2port->append = (ps2port->append + 1) & BUFFER_SIZE; As a result, append never advances. Since gscps2_report_data() only reports bytes while act != append, the receive buffer always appears empty and no keyboard or mouse data reaches the serio core. Restore the omitted index update.

2025-10-01Drivers: hv: Add CONFIG_HYPERV_VMBUS optionMukesh Rathor
At present VMBus driver is hinged off of CONFIG_HYPERV which entails lot of builtin code and encompasses too much. It's not always clear what depends on builtin hv code and what depends on VMBus. Setting CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin adds even more confusion. VMBus is an independent module and should have its own config option. Also, there are scenarios like baremetal dom0/root where support is built in with CONFIG_HYPERV but without VMBus. Lastly, there are more features coming down that use CONFIG_HYPERV and add more dependencies on it. So, create a fine grained HYPERV_VMBUS option and update Kconfigs for dependency on VMBus.

2025-08-21Input: include export.h in modules using EXPORT_SYMBOL*()Dmitry Torokhov
A number of modules in the input subsystem use EXPORT_SYMBOL() and friends without explicitly including the corresponding header <linux/export.h>. While the build currently succeeds due to this header being pulled in transitively, this is not guaranteed to be the case in the future. Let's add the explicit include to make the dependencies clear and prevent future build breakage. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2025-02-25Input: i8042 - swap old quirk combination with new quirk for more devicesWerner Sembach
Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. We could not activly retest these devices because we no longer have them in our archive, but based on the other old Clevo barebones we tested where the new quirk had the same or a better behaviour I think it would be good to apply it on these too.

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. While the old quirk combination did not show negative effects on these devices specifically, the new quirk works just as well and seems more stable in general.

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. The PB71RD keyboard is sometimes laggy after resume and the PC70DR, PB51RF, P640RE, and PCX0DX_GN20 keyboard is sometimes unresponsive after resume. This quirk fixes that.
