PS/2 keyboard not recognized by input_server

[wkornewald]

The keyboard is detected correctly and input is received by the PS/2 bus manager, but it's dropped because the device isn't opened. This must be a bug in the input_server add-on.

probably useless keyboard input_server device log

[wkornewald]

This bug is probably related to #155, but my keyboard is never recognized. I'm using a Sony laptop (VGN-FS115M). After boot the keyboard LEDs are off and can't be changed (it's like the keyboard is dead). In the syslog you will see that I pressed the following keys: CapsLock, NumLock, a, b, c, CTRL, ALT Nothing ever happened.

Is there anything else you need?

[wkornewald]

syslog with DEBUG=1 for ps/2 driver, input_server, and input_server add-on

[wkornewald]

I've remove the syslog mouse movement output to be more useful.

It looks like the keyboard controller ignores the a8 command, so the ff (reset) command goes to the mouse 3 instead of keybaord. I'll try to find a workaround.

specification:

The routing prefix (90h, 91h, 92h, or 93h) is written to output port 64h, followed by any of the following host actions:

Routing prefix + output A8h to port 64h This command enables the selected AUX port [...]

Routing prefix + output a byte to port 60h This command sends the indicated byte to the AUX port selected by the routing prefix.

(port 64 is ctrl, port 60 is data)

Please try this:

modify src/add-ons/kernel/bus_managers/ps2/ps2_common.c, function ps2_setup_active_multiplexing

and insert at:

ps2_command(0x93, NULL, 0, NULL, 0); ps2_command(0xa8, NULL, 0, NULL, 0);

->> here

*enabled = true; return B_OK;

one of the following:

a) ps2_command(0xa8, NULL, 0, NULL, 0); b) ps2_write_data(0x00); c) ps2_write_data(0xF6); d) ps2_write_data(0xFF);

I would like to see both syslogs of testing using a) and b), if none of them works, please also test c) and d).

[wkornewald]

(b)

(d)

[wkornewald]

Unfortunately, nothing worked.

[marcusoverhagen]

Please try this instead

ps2_command(0x93, (const uint8 *)"", 1, NULL, 0);

If that still doesn't work, try

ps2_command(0x90, (const uint8 *)"\xff", 1, NULL, 0);

As last resort, insert all these:

ps2_command(0x93, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x92, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x91, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x90, (const uint8 *)"\xff", 1, NULL, 0);

Replying to marcusoverhagen:

Please try this instead

ps2_command(0x93, (const uint8 *)"", 1, NULL, 0);

That worked, thanks!

Just for the sake of testing I also tried: ps2_command(0x93, (const uint8 *)"\xff", 1, NULL, 0); This worked, too. Both syslogs are attached.

If that still doesn't work, try

ps2_command(0x90, (const uint8 *)"\xff", 1, NULL, 0);

Haiku seemed to not have crashed, but all input devices (including my USB mouse) stopped working. That rented my laptop unbootable. I had to remove the battery to make it boot, again.

As last resort, insert all these:

ps2_command(0x93, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x92, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x91, (const uint8 *)"\xff", 1, NULL, 0); ps2_command(0x90, (const uint8 *)"\xff", 1, NULL, 0);

Same crashing behavior.

I also tried the following with the same results: ps2_command(0x93, (const uint8 *)"", 1, NULL, 0); ps2_command(0x92, (const uint8 *)"", 1, NULL, 0); ps2_command(0x91, (const uint8 *)"", 1, NULL, 0); ps2_command(0x90, (const uint8 *)"", 1, NULL, 0);

Don't know if that's useful.

[wkornewald]

Do you think the problem was fixed correctly, now? Or do you want to test something else before committing anything?

[marcusoverhagen]

The results indicate that your keyboard still doing something erattic, and I really don't like the current "solution".

According to the PS/2 active multiplexing specification, (available at ​http://www.synaptics.com/decaf/utilities/ps2-mux.PDF ) the default of the AUX port is supposed to be disabled=0 after switching to multiplexing.

This means we can hopefully drop the enable sequence completely.

Please modify ps2_setup_active_multiplexing() and remove the lines below the dprintf, then compile test and attach a syslog.

[...]
dprintf("ps2: active multiplexing v%d.%d enabled\n", (in >> 4), in & 0xf);
// remove everything that was at this place
*enabled = true;
return B_OK;
[...]

I hope this helps. Sorry that it took so long...
