2007-07-18Input: add driver for Fujitsu serial touchscreensDmitry Torokhov
These serial touchscreens are found on some Fujitsu lifebook P-series laptops, and the B6210. Using this requires a new version of inputattach and doing: inputattach -fjt /dev/ttyS0 Big thanks to Stephen Hemminger for testing it and making it work on his B6210 laptop.

2007-07-18Input: ads7846 - re-check pendown status before reporting eventsSemih Hazar
Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

2007-07-18Input: ads7846 - introduce sample settling delaySemih Hazar
The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-05-22Input: ads7846 - SPI_CPHA mode bugfixSemih Hazar
In commit [1] the SPI mode is set to 1, but it should be 0. As stated in the commit, ads784x samples the data on the rising edge. SPI mode 1 samples on the falling edge [2] though. The root cause of this is a bug in the omap_uwire code, which treats CPHA=1 incorrectly; so these two bugs cancel each other out on one of the main regression test platforms for this driver.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.
