* 2.6.0-test2 has i8042 mux problems @ 2003-07-28 2:13 dean gaudet 2003-07-28 3:59 ` Andries Brouwer ` (2 more replies) 0 siblings, 3 replies; 13+ messages in thread From: dean gaudet @ 2003-07-28 2:13 UTC (permalink / raw) To: linux-kernel this was a bug i reported back a few versions as well -- and i don't think i received any responses (nor from the maintainer). i've got a box on which 2.4.x works fine, but 2.6.0-test2 gets into a snit when it's trying to initialize the i8042. i can get 2.6.0-test2 to boot if i add "i8042_nomux". the mux initialization code seems kind of ... wonk -- it seems to write values to the registers then read back and if the value is the same then it assumes the mux is there. that seems way too likely to be broken in situations when the mux isn't there... it'd be better to be looking for some value which is different after writing. the southbridge in this system is the ali1563. if it helps i can supply a complete trace of in/out on ports 0x60 and 0x64. thanks -dean Loading test..........................

I am not sure, if i understand it, but here I could not use my old keyboard with kernel 2.6.0-test1. The kernel switched off the keyboard conntroller while booting. My keyboard is about 10-12 years old, but it always worked. There should be a switch for lilo/grub to override the testing. I have got a via KT400a chipset.

Yes, the new keyboard driver knows far too much about keyboards, and that knowledge is right only in 98% of the cases. No doubt we'll be forced to back out a lot of probing done now. Nevertheless it would be interesting to see precisely what happens. Could you try to change the #undef DEBUG in drivers/input/serio/i8042.c into #define DEBUG and report what output you get at boot time? ^ permalink raw reply [flat|nested] 13+ messages in thread

This is the only debug message i can see without keyboard. serio: i8042 AUX Port at 0x60,0x64 irq 12 input: AT set2 keyboard on isa0060/serio0 serio i8042 KBD port at 0x60,0x64 irq 1 Can you tell me how to force the driver to enable my keyboard anyways?

Let me comment it. ------------------------------------------------------------- check_mux: First we probe for a Synaptics mux. Find none. check_aux: Then we probe for a PS/2 mouse port. Find one. Good. Found something. Call serio_register_port(). This searches for attached devices. We know already that it is the PS/2 mouse port, but who knows what might be connected. Let us try all devices we know about.

No devices connected to this port, but at least we have a port: > serio: i8042 AUX port at 0x60,0x64 irq 12 Then we continue, and check the keyboard side of the i8042 controller. Things work satisfactorily, we detect a keyboard. Silly enough we set it to scancode Set 2, but nevertheless give commands that are only meaningful for scancode Set 3. Keyboards that know only about Set 2 will be unhappy. > input: AT Set 2 keyboard on isa0060/serio0 > serio: i8042 KBD port at 0x60,0x64 irq 1 OK, found keyboard. ------------------------------------------------------------- So far the story of your debug file.

Its about 14 years old and its switchable between AT and XT. And it has a DIN-Plug. I am using an adaptor. I just opend it and now i write you the chips inside it: K450A/452A R.O.C.

I can confirm this. I have an Amilo A laptop with the following sb: 00:07.0 ISA bridge: ALi Corporation M1533 PCI to ISA Bridge [Aladdin IV] without "i8042_nomux" the keyboard is recognized fine, but no mouse is found on the mux.

With the option everything works fine. that's slightly different than what i get without i8042_nomux, and a keyboard & mouse plugged in, the system crashes and burns badly during boot. without the keyboard and mouse it boots fine. with i8042_nomux it's a lot happier. my system is a test board for a new processor with the ali1563 -- which is a newer hypertransport variant of the 1533/1535. i'm not sure yet if there are production boards with the 1563. but it's nice to know it happens with your 1533 as well. andries -- i'll send you a copy of the in/out traffic (it's a bit large for posting). -dean ^ permalink raw reply [flat|nested] 13+ messages in thread
