2006-10-21IRQ: Maintain regs pointer globally rather than passing to IRQ handlersMauro Carvalho Chehab
Kernel-sync: This patch is required to allow compilation of the tree with kernel 2.6.19. This is the original description of the original patch, signed by David Howells <dhowells@redhat.com>: 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. Signed-Off-By: Mauro Carvalho Chehab <mchehab@infradead.org>

From: Michael Krufky <mkrufky@linuxtv.org> Some cx88-blackbird boards use an external adc, but not necessarily for all inputs. Thus, this needs to be configurable on the card level for each input. This patch allows for the usage of the external adc to be determined by a bit setting in the cx88_input struct for cards based on the cx88 blackbird design.

2006-10-15pvrusb2: Implement IR reception for 24xxx devicesMike Isely
From: Mike Isely <isely@pobox.com> Unlike 29xxx devices, the 24xxx model series does not have a dedicated I2C device for reception of IR codes. Instead IR is handled directly by the FX2 microcontroller and the results are communicated via commands to the FX2. Rather than implement a whole new IR reception pathway for 24xxx devices, this changeset instead emulates the presence of the 29xxx device's I2C based IR receiver by intercepting commands to that chip and issuing appropriate FX2 commands to do the needed action. This has the result of allowing all the usual IR frameworks (ir-kbd-i2c or lirc) to continue working unmodified for 24xxx devices. Signed-off-by: Mike Isely <isely@pobox.com>

2006-10-14Fix DBV_FE_CUSTOMISE for card drivers compiled into kernelTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> When a front-end is disabled, card drivers that use it are compiled with a stub version of the front-end's attach function. This way they have no references to the front-end's code and don't need it to be loaded. If a card driver is compiled into the kernel, and a front-end is a module, then that front-end is effectively disabled wrt the card driver. In this case, the card driver should get the stub version. This was not happening. The stub vs real attach function selection is changed so that when the front-end is a module the real attach function is only used if the card driver is a module as well. This means a module front-end will be supported by card drivers that are modules and not supported by card drivers compiled into the kernel. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
