* Input: libps2 - mark expected switch fall-throughGustavo A. R. Silva2019-05-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/input/serio/libps2.c: In function ‘ps2_handle_ack’: drivers/input/serio/libps2.c:407:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ps2dev->flags & PS2_FLAG_NAK) { ^ drivers/input/serio/libps2.c:417:2: note: here case 0x00: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.

* Input: i8042 - signal wakeup from atkbd/psmouseDmitry Torokhov2019-04-041-3/+0
| | | | | | | | | | | Instead of signalling wakeup directly from i8042, let psmouse and atkbd drivers execute basic protocol handling and only then signal wakeup condition. This solves the issue where we increment wakeup counter simply because we are getting responses from keyboard/mouse to the commands we ourselves send to them as part of suspend transition.

* Input: i8042 - rework DT node name comparisonsRob Herring2019-02-181-11/+10
| | | | | | | | | | | | | Convert string compares of DT node names to use of_node_name_eq helper instead. For the root node on SUN DT, we need to retrieve the 'name' property as it is the rare case where the 'name' property and node name differ. With both changes, it removes direct access to the node name pointer. While at it, convert the open coded loop to use for_each_child_of_node().

| | * Input: hyper-v - fix wakeup from suspend-to-idleVitaly Kuznetsov2018-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.

Returning long when native method had never allowed that is ridiculous and inconvenient. More importantly, change the caller; if ldisc ->compat_ioctl() is NULL or returns -ENOIOCTLCMD, tty_compat_ioctl() will try to feed cmd and compat_ptr(arg) to ldisc's native ->ioctl(). That simplifies ->compat_ioctl() instances quite a bit - they only need to deal with ioctls that are neither generic tty ones (those would get shunted off to tty_ioctl()) nor simple compat pointer ones. Note that something like TCFLSH won't reach ->compat_ioctl(), even if ldisc ->ioctl() does handle it - it will be recognized earlier and passed to tty_ioctl() (and ultimately - ldisc ->ioctl()). For many ldiscs it means that NULL ->compat_ioctl() does the right thing. Those where it won't serve (see e.g. n_r3964.c) are also easily dealt with - we need to handle the numeric-argument ioctls (calling the native instance) and, if such would exist, the ioctls that need layout conversion, etc. All in-tree ldiscs dealt with.

This happens because the EC generates a SCI interrupt in this scenario. That is no longer true on modern laptops based on Intel WhiskeyLake, including Acer Swift SF314-55G, Asus UX333FA, Asus UX433FN and Asus UX533FD. We confirmed with Asus EC engineers that the "Modern Standby" design has been modified so that the EC no longer generates a SCI in this case; the keyboard controller itself should be used for wakeup. In order to retain the standard behaviour of being able to use the keyboard to wake up the system, enable serio wakeups by default on platforms that are using s2idle.

As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS.

| | | * Input: libps2 - relax command byte ACK handlingDmitry Torokhov2018-02-031-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we probe PS/2 devices we first issue "Get ID" command and only if we receive what we consider a valid keyboard or mouse ID we disable the device and continue with protocol detection. That means that the device may be transmitting motion or keystroke data, while we expect ACK response. Instead of signaling failure if we see anything but ACK/NAK let's ignore "garbage" response until we see ACK for the command byte (first byte). The checks for subsequent ACKs of command parameters will continue be strict. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
| | | * Input: libps2 - support retransmission of command dataDmitry Torokhov2018-02-031-32/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The devices are allowed to respond to either command byte or command parameter with a NAK (0xfe), and the host is supposed to resend the "correct" byte. The device then will either respond with ACK or ERR (0xfc). Let's teach libps2 to handle the NAK responses properly, so that individual drivers do not need to handle them.

We do not introduce a new module parameter, but rater rely on the kernel having dynamic debug facility enabled (which most everyone has nowadays). Enable with: echo "file libps2.c +pf" > /sys/kernel/debug/dynamic_debug/control or add "libps2.dyndbg=+pf" to the kernel command line. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Also use unsigned int for the command codes and timeouts, and have ps2_handle_ack() and ps2_handle_response() return bool instead of int, as they do not return error codes but rather signal whether a byte was handled or not handled. ps2_is_keyboard_id() now returns bool as well.

NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
