| | | | | | | | | since commit fcaf71fd51f9cfc504455d3e19ec242e4b2073ed struct mmc_host does not have a dev field. Retrieve the device with mmc_dev() instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* 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.

* [MMC] Move set_ios debugging into mmc.cRussell King2006-05-04
| | | | | | | | Rather than having every driver duplicate the set_ios debugging, provide a single version in mmc.c which can be expanded as we add additional functionality. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [MMC] PXA: reduce the number of lines PXAMCI debug usesRussell King2006-05-02
| | | | | | | | | | There's no reason for the PXAMCI debug code to print so many lines - it causes the kernel buffer to overflow when trying to debug this driver. Remove some debug messages which are duplicated by core code, and combine other messages, resulting in fewer characters written to the kernel log.

* [MMC] PXA and i.MX: don't avoid sending stop command on errorRussell King2006-05-02
| | | | | | | | Always send a stop command at the end of a data transfer. If we avoid sending the stop command, some cards remain in data transfer mode, and refuse to accept further read/write commands. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [MMC] pxamci: fix data timeout calculationRussell King2006-04-24
| | | | | | | | | | | The MMC layer gives us two parts for the timeout calculation - a fixed timeout in nanoseconds, and a card clock-speed dependent part. The PXA MMC hardware allows for a timeout based on the fixed host clock speed only. This resulted in some cards being given a short timeout, and therefore failing to work.

* [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King2005-10-28
| | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

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!
