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.

2006-03-31[PATCH] pcmcia: use bitfield instead of p_state and stateDominik Brodowski
Instead of the two status values struct pcmcia_device->p_state and state, use descriptive bitfields. Most value-checking in drivers was invalid, as the core now only calls the ->remove() (a.k.a. detach) function in case the attachement _and_ configuration was successful.

2006-03-31[PATCH] pcmcia: add return value to _config() functionsDominik Brodowski
Most of the driver initialization isn't done in the .probe function, but in the internal _config() functions. Make them return a value, so that .probe can properly report whether the probing of the device succeeded or not. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-03-31[PATCH] pcmcia: remove dev_link_t and client_handle_t indirectionDominik Brodowski

2006-03-31[PATCH] pcmcia: embed dev_link_t into struct pcmcia_deviceDominik Brodowski
Embed dev_link_t into struct pcmcia_device(), as they basically address the same entity. The actual contents of dev_link_t will be cleaned up step by step. This patch includes a bugfix from and signed-off-by Andrew Morton. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-03-31[PATCH] pcmcia: remove unneeded Vcc pseudo settingDominik Brodowski

2006-03-31[PATCH] pcmcia: default suspend and resume handlingDominik Brodowski
In all but one case, the suspend and resume functions of PCMCIA drivers contain mostly of calls to pcmcia_release_configuration() and pcmcia_request_configuration(). Therefore, move this code out of the drivers and into the core. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2006-03-31[PATCH] pcmcia: add pcmcia_disable_deviceDominik Brodowski

- change interface of the reset functions from Scsi_Cmnd to Scsi_Host. - add functions with the original interface and rename the new functions to reflect the new interface. - call these from the pcmcia driver, thereby avoiding the need to construct a (broken) Scsi_Cmnd from a Scsi_Host. - just run the bh if the interrupt is from the controller and if so ensure that it's only called once per interrupt.

2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ā†µDominik Brodowski
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2005-07-07[PATCH] pcmcia: remove client services version (fix)Pavel Roskin
One correction is needed. Changes are not needed for drivers/scsi/pcmcia/nsp_cs.c because it uses versioning in the compatibility part, which is never used in 2.6 kernels. The only right thing we could to that compatibility code would be to remove it throughout the file, but that would be a separate patch.

2005-07-07[PATCH] pcmcia: remove client services versionPavel Roskin
The Linux PCMCIA code has some data that was apparently used (or meant to be used) to ensure that only proper client drivers are loaded. This is now ensured (to a certain degree) by the fact that the most client drivers are part of the kernel. Also, the version information has not been updated despite major changes in PCMCIA API. This has made it meaningless. This patch removes servinfo_t and pcmcia_get_card_services_info. They are not used in any userspace utilities such as pcmcia-cs and pcmciautils. drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly. CS_RELEASE and CS_RELEASE_CODE are removed. include/pcmcia/version.h is empty now. It will be removed later, but for now it's left in the tree to avoid touching all PCMCIA clients. The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c, which uses CS_RELEASE_CODE.

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!
