2007-10-19Console keyboard events and accessibilitySamuel Thibault
Some blind people use a kernel engine called Speakup which uses hardware synthesis to speak what gets displayed on the screen. They use the PC keyboard to control this engine (start/stop, accelerate, ...) and also need to get keyboard feedback (to make sure to know what they are typing, the caps lock status, etc.) Up to now, the way it was done was very ugly. Below is a patch to add a notifier list for permitting a far better implementation, see ChangeLog above for details. You may wonder why this can't be done at the input layer. The problem is that what people want to monitor is the console keyboard, i.e. all input keyboards that got attached to the console, and with the currently active keymap (i.e. keysyms, not only keycodes). This adds a keyboard notifier that such modules can use to get the keyboard events and possibly eat them, at several stages: - keycodes: even before translation into keysym. - unbound keycodes: when no keysym is bound. - unicode: when the keycode would get translated into a unicode character. - keysym: when the keycode would get translated into a keysym. - post_keysym: after the keysym got interpreted, so as to see the result (caps lock, etc.) This also provides access to k_handler so as to permit simulation of keypresses.

2007-10-18IPMI: new NMI handlingCorey Minyard
Convert over to the new NMI handling for getting IPMI watchdog timeouts via an NMI. This add config options to know if there is the ability to receive NMIs and if it has an NMI post processing call. Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.

2007-10-18IPMI: add polled interfaceCorey Minyard
Currently the IPMI watchdog timer sets the watchdog timeout on a panic, but it doesn't actually poll the interface to make sure the message goes out.

2007-10-18IPMI: remove bogus semaphore from watchdogCorey Minyard
Lockdep was giving an error when loading the IPMI watchdog module. It turns out that if you try to claim a lock in a parameter handling routine, lockdep won't see that lock as "static" yet because the module is not yet on the module list, so it will complain. However, the semaphore in question is completely unnecessary. So just remove it.

2007-10-18IPMI: don't init irq until readyCorey Minyard
Patrick found a race at startup. Interrupts were being enabled for the IPMI interface before the driver was really ready to handle them. This could result in an oops if something was pending on the interface at startup and interrupt were already enabled (technically shouldn't happen, but need to cover for this in real life). So move the IRQ setup to the code that starts the actual IPMI processing.

Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

2007-10-17tty: expose new methods needed for drivers to get termios rightAlan Cox
This adds three new functions (or in one case to be more exact makes it always available) tty_termios_copy_hw Copies all the hardware settings from one termios structure to the other. This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers.

2007-10-17Tweak /proc/ipmi removalAlexey Dobriyan
Driver does proc_mkdir("ipmi", NULL); but remove_proc_entry(proc_ipmi_root->name, &proc_root); This is OK and working if only slightly inconsistent. Also changing proc_root to NULL will help OpenVZ which has multiple proc roots and, as we now know, requires matching parents in such cases.

2007-10-17tpm: pay attention to IRQ info from PNPBjorn Helgaas
If we discover the TIS TPM device via PNP, use the PNP IRQ information rather than probing for an IRQ. If PNP shows no IRQ, run the TPM in polling mode.
