commit 5fc27b098dafb8e30794a9db0705074c7d766179 upstream. Touchpad on this laptop is not detected properly during boot, as PNP enumerates (wrongly) AUX port as disabled on this machine. Fix that by adding this board (with admittedly quite funny DMI identifiers) to nopnp quirk list.

This problem has been noted before, perhaps only occurring with BIOS 1.57 and later.[1][2][3][4][5] Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago and although the [BIOS changelog] notes "Fixed an issue of UEFI touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be insufficient. Setting i8042.reset=1 or adding 33474HU to the reset list avoids the issue on my system from either warm or cold boot.

commit ebc68cedec4aead47d8d11623d013cca9bf8e825 upstream. The Acer Aspire 5738z has a button to disable (and re-enable) the touchpad next to the touchpad. When this button is pressed a LED underneath indicates that the touchpad is disabled (and an event is send to userspace and GNOME shows its touchpad enabled / disable OSD thingie). So far so good, but after re-enabling the touchpad it no longer works. The laptop does not have an external ps2 port, so mux mode is not needed and disabling mux mode fixes the touchpad no longer working after toggling it off and back on again, so lets add this laptop model to the nomux list.

Previously, on typical consumer laptops, pressing a key on the keyboard when the system is in suspend would cause it to wake up (default or unconditional behaviour). 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.

Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. 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. With MUX enabled, touch sensor buttons are detected as separate device (and left disabled as there's currently no driver), fixing all touchpad problems.

Reset i8042 before probing because of insufficient BIOS initialisation of the i8042 serial controller. This makes Synaptics touchpad detection possible. Without resetting the Synaptics touchpad is not detected because there are always NACK messages from AUX port.

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
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.

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>

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.

Debugging via i8042.debug and analyzing raw PS/2 data stream may be cumbersome as you need to locate the boundaries of commands, decipher the sliced commands, etc, etc. Let's add a bit more high level debug statements for ps2_sendbyte(), ps2_command(), and ps2_sliced_command(). 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>

Instead of using unsigned char for the byte data switch to using u8. 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.

struct timeval is not y2038 safe, and what mlc->instart do is scheduling a task in a fixed timeout, so jiffies is the simplest choice here. In hilse_donode(), the expires in mod_timer equals jiffies + intimeout - (now - instart) If we use jiffies in 'now', the expires equals instart + intimeout So, all we need to do is that making sure expires is a future timestamp before passed it to mod_timer.
