Subject: Re: Synaptics Touchpad workaround for strange behavior after Sync loss (With Patch).

Hi!

The sync problems have so far been found to be caused by two possible
causes:

1) Too long disabled interrupts. This is usually caused by ACPI
BIOS, when some application is polling for battery status
too often.

2) Incorrectly working timer (jiffies). This maybe caused by
using the ACPI timer instead of the regular PIT one. Check
the config.

Both these causes break the lost bytes detection mechanism in the ps/2
code. It then thinks that a byte was lost (and thus the sync, too), but
in reality everything is OK. This in turn causes two consecutive
incorrectly parsed packets.

Subject: [PATCH 1/2] Synaptics rate switching

===================================================================

[email protected], 2004-01-10 02:42:42-05:00, [email protected]
Input: Allow switching between high and low reporting rate for Synaptics
touchpads in native mode. Synaptics support 2 report rates - 40
and 80 packets/sec; report rate must be set using Synaptics mode
set command. Rate is controlled by psmouse.rate parameter, values
greater or equal 80 will set 'high' rate. (psmouse.rate defaults
to 100)

Using low report rate should help slower systems or systems
spending too much time in SCI (ACPI).

Hi,

As I wrote in my other email the patch as it written does not discard
2 first packets after restoring synchronization, instead it ignores every
2nd packet.

It seems that your laptop can't keep up with 480 bytes/sec data stream that
Synaptics generates in 'high' report rate mode (80 packets/sec, 6 bytes per
packet). Luckily Synaptics offers low rate mode, 40 packets/sec, and I think
you should get the same result as by your patch switching your touchpad in
that mode.

I am going to send 2 patches, one that allows switching high and low rate
for Synaptics using psmouse.rate option (>=80 sets high rate and its default
state). You should try psmouse.rate=40 (or just rate=40 if psmouse is compiled
as a module). The second patch makes psmouse check status of received byte and
drop it early if i8042 reports timeout or parity error.

The patches are on top of my other input patches, you can find all of them at
http://www.geocities.com/dt_or/input/2_6_1/

Or you can grab 2.6.1-mm1 and apply just the 2 I am sending...

I am very interested in results.

Thank you in advance,

Dmitry

Hmmm...

Needed me hours to apply the patches, don't know why, ---

No more bad clicks, no more keypress events --- but still loosing sync 2*n
times at once, most of the times when changing the console, mostly at the
1st byte, the first of the two times occasionally at the 4th...

...New error message: bad data from KBC - timeout every about third sync
loss.

Strange thing is: The sync losses mostly occour half a second after i have
finished using the touchpad, and occasionally when I don't use it at all...

And they occour nearly everytime I switch consoles. (Not using framebuffer,
X or something like this.)

Changing the data rate from the touchpad changes nothing.

Looked at all kernel options... If it is a timer problem --- ho can I find
out this?

Yours,

Gunter.

Subject: Re: [PATCH 1/2] Synaptics rate switching

Tried it. Doesn't change a thing. Means: I get about half the number of
warning messages, but that just corresponds to half the number of packets.

What helps a lot, but not to 100% (get bad keypresses anyway) is
totally deactivating the ACPI. Killing all processes that access /proc/acpi
seems again to help a bit.

And The number of Warnings seemingly increases with the labtop
temperature... In a really cold room I get nearly no warnings at all.
Jitter? Hardware, that is simply broken?

Anyway, --- with Dmitrys patches I get hardly ever little bad events, just
warnings --- and --- well... I can live with them,

Gunter.

The best ways are the most straightforward ways. When you're sitting around
scamming these things out, all kinds of James Bondian ideas come forth, but
when it gets down to the reality of it, the simplest and most straightforward
way is usually the best, and the way that attracts the least attention.
Also, pouring gasoline on the water and lighting it like James Bond doesn't
work either.... They tried it during Prohibition.

I also believe some of the troubles comes from that we never check all
error codes from the mux: If mux is disabled for some reason all bytes are
stamped as timed out. The only way to recover is to reboot. And (I am
speculating here) if for some reason the mux believe the touchpad is
removed and connected the touchpad sends 2 bytes ack.

I dont have a machine with active multiplexing so the the patch is
untested. It warns when the mouse is removed, and tries to recover
if multiplexing is disabled.

Can you check whether you've enabled usage of the ACPI timer for
timekeeping?

If yes, disable it.

Actually, since you mentioned temperature.. is CPUFREQ active or does
the ACPI throttle your processor to a lower frequency if it gets hot?

Hi,

It is a good stuff but we probably want not only restore mux mode
but also do serio_reconnect on all ports to make sure all devices are
properly configured. But it gets way too big for interrupt handler.
I am thinking that if mux error is detected the only thing that should
be done in i8042_interrupt is disabling the controller and then use
schedule_work to schedule the rest.

Also, if we get SERIO_REMOVED condition we should just do serio_reconnect
right away and let it sort through the device state.

What do you think?

Hi Gunter,

I have some additions to the last patch and I'd like you to give it a spin.
Also, could you please define DEBUG symbol in drivers/input/serio/i8042.c
and send me your dmesg with boot data and also when the touchpad loses
sync. I'd like to see it in all gory details :)

Thank you,

Dmitry

Input: Change the way timeouts/parity errors are handled:
- Only complain about errors from keyboard controller if mouse
is activated
- Reset packet count to 0 as the next received byte will most
likely be the first byte of a new packet
- If expecting an ACK from the mouse set NACK condition

It's nice, but er definitely shouldn't call i8042_enable_mux() from the
interrupt handler, because i8042_command() waits for characters arriving
in the interrupt handler, so we could get into rather nasty recursions.

cpufreq is deactivated for all tests, but seems not to make problems...

ACPI --- Pow... never thought of that... ...But sync losses occour even if
my labtop doesn't even see the need for switching on the CPU fan. Anyway,
povray makes the CPU really hot, and doesn't make things worse...

...and the problem occours directly after startup, too... Don't think this
will be the problem,

Hmmm... This patch did something: I think, I get less warnings and no
warning at all at startup...

But defining DEBUG didn't produce any message, that seems to be of interest
to me...

Appended an complete dmesg from switching on to the first error messages...

And: Another strange observation: klling gpm (X is not running) results in
odd numbers of warnings contrary to even ones when gpm runs.

THE MX IS GOOD FOR THE ECONOMY. One important reason we have a Defense
Department is that when we give it money, it spends it, which creates
jobs, whereas if we left the money in the hands of civilians, we don't
know what they'd do with it. Probably put it in open trenches and set
it on fire. The MX will create an especially large number of jobs
because of the number of warheads it carries. It carries a total of 10
warheads. This creates a great deal of employment, because you have
your Warhead Makers, your Warhead Lifters, your Persons Who Tap the
Warheads Gently with Rubber Mallets to Wedge Them All Snugly Into the
Nose Cone, your Persons Who Just Walk Around Playing Soothing Cassettes
by Recording Artists such as Perry Como So We Don't Have Any More
Episodes Where a Worker Who is Experiencing Some Strain Sticks a
Warhead in the Employee Cafeteria Microwave and Sets It On Roast, etc.
We are talking about a lot of jobs.

Hmmm... Now I get an "Reverted to legacy aux mode" after about every third
resync of the driver, and sometimes odd and sometimes even numbers of sync
losses...

But this patch also seems to fix bad clicks, tried for some minutes, and
still got none.

How often is that? X/minute. I do not expect many "reverted .." messages,
but if there is, then I believe the mux ver 1.1 has added some extra error
codes that we se as a revert.

Are you sure? The i8042_command does spin_lock_irqsave(&i8042_lock,
flags), i8042_wait_read, i8042_read_data and unlock. It seems a good place
for me as the 8042s buffer is just flush by the interrupt. Well except for
the fact it is in the interrupt handler :)

I cannot see a simple/fast solution: All data read in the interrupt must
be processed otherwise kbd data might be lost. I dont want
I8042_BUFFER_SIZE calls to serio_rescan/reconnect, as serio is not smart
enought to only do it once. The mux port number(s) must be remembered if
serio is called after the loop. I dont like any further calls to
i8042_flush as it troughs away both kbd and aux data.

hmm, I actually want the handler to look something like:

if (str & I8042_STR_MUXERR)
i8042_handle_aux_data
else
i8042_handle_kbd_data

That way i8042_flush can call handle_*_data depending on what to flush.

Or the BIOS powermanagement is touching the controller in a way the MUX

Ahh, yeah, I forgot. Gee, and I wrote i8042_command.

Consider the loop gone. It already is in my version.

ca. 1--70 times/min, most of the times ca. 5 times/min, but sometimes
more than one per second for hours or so... Don't find any pattern behind
it.

Does booting with i8042.i8042_nomux=1 help? That should keep the MUX in
legacy mode. (well, depending on the kernel version it's either i8042.nomux
or i8042.i8042_nomux, -mm1 and my patches use former, in 2.6.1 vanilla uses
later form).
