* [PATCH] Correct misc_register return code handling in several driversNeil Horman2006-12-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Clean up several code points in which the return code from misc_register is not handled properly. Several modules failed to deregister various hooks when misc_register fails, and this patch cleans them up. Also there are a few modules that legitimately don't care about the failure status of misc register. These drivers however unilaterally call misc_deregister on module unload. Since misc_register doesn't initialize the list_head in the init_routine if it fails, the deregister operation is at risk for oopsing when list_del is called. The initial solution was to manually init the list in the miscdev structure in each of those modules, but the consensus in this thread was to consolodate and do that universally inside misc_register.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

| | | | | | | | | | | | | | | | | | | | | | | A driver for laptop buttons using an x86 BIOS interface that is apparently used on quite a few laptops and seems to be originating from Wistron. This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000 (i.e. it can detect the laptop using DMI and it contains the keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G (probably can't be reliably autodetected, requires a module parameter), adding other laptops should be easy. In addition to reporting button presses to the input layer the driver also allows enabling/disabling the embedded wireless NIC (using the "Wifi" button); this is done using the same BIOS interface, so it seems only logical to keep the implementation together. Any flexibility possibly gained by allowing users to remap the function of the "Wifi" button is IMHO not worth it when weighted against the necessity to run an user-space daemon to convert button presses to wifi state changes.
