* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] CONFIG_PM=n slim: sound/oss/cs46xx.cAlexey Dobriyan2006-09-29
| | | | | | | | | | | | | | | | | Remove some code which is unneeded if CONFIG_PM=n. * Make suspend/resume registration look like the rest of drivers: #ifdef CONFIG_PM in struct pci_driver, prototypes, actual hooks. * Drop CS46XX_ACPI_SUPPORT. It logically duplicated CONFIG_PM. It was hardcoded to 1 approx forever (ALSA merge just moved driver to sound/oss/). * After previous point, sound/oss/cs46xxpm-24.h removed as being useless. * As side effect selling (unused) static inline functions as suspend/resume hooks funkiness removed too.

* [PATCH] OSS: cs46xx cleanup and tiny bugfixJesper Juhl2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's a patch for cs46xx that - (mostly) cleans up the cs46xx driver according to CodingStyle - removes a bunch of pointless casts - fixes a small, potential use of uninitialized variable, bug - reduces the size of the compiled code by 36 bytes - reduces the size of the source file by 1831 bytes I know I should probably have split this into bits, but since I only thought of that *after* doing all the edits, splitting it up would have been a royal pain. And since these are all pretty trivial changes I thought I'd just submit the one huge patch and hope people could live with it (if not, then just tell me and I'll split it). The bug fix that's in there may be hard to spot, so I'll point it out. It's the - int val, valsave, mapped, ret; + int val, valsave, ret; + int mapped = 0; bit. Without that change we may use `mapped' uninitialized if, in cs_ioctl, the first test of "if(state)" is false and the second "if(state)" test is true.

* [PATCH] oss: remove deprecated PM interface from cs46xx driverPatrick Mochel2006-01-06
| | | | | | | | | | | | | | | | | | | This change removes the old, deprecated interface from the cs46xx driver, including the pm_{,un}register() calls, the local storage of the pmdev object and the reference to the old header files. This change is done to assist in eradicating the users of the legacy interface so as to help facilitate the removal of the interface itself. Note this driver has PCI PM hooks which are set properly. It also has the ability to trigger suspend/resume from an ioctl. This functionality was not touched, though it could use a serious review if this driver continues to persist in the mainline tree.. Note that this driver has been obsoleted by an ALSA equivalent.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
