* [NET] drivers/net: statistics cleanup #1 -- save memory and shrink codeJeff Garzik2007-10-10
| | | | | | | | | | | | | | | | | We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.

* 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] smc91x: allow for dynamic bus access configsNicolas Pitre2006-03-21
| | | | | | | | | | | | | | All accessor's different methods are now selected with C code and unused ones statically optimized away at compile time instead of being selected with #if's and #ifdef's. This has many advantages such as allowing the compiler to validate the syntax of the whole code, making it cleaner and easier to understand, and ultimately allowing people to define configuration symbols in terms of variables if they really want to dynamically support multiple bus configurations at the same time (with the unavoidable performance cost).

* [PATCH] IRQ type flagsRussell King2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

* [PATCH] smc91x: fix bank mismatchRussell King2005-11-18
| | | | | | | | | | | | | | | | | | The smc91x driver relies upon register bank 2 being selected whenever the interrupt handler is called. This isn't always so, especially if we have a link change event during PHY configuration. This results in register bank 0 being selected when the interrupt handler is called, causing the wrong registers to be read for the IRQ mask and status. In turn, this causes us to spin with a permanently asserted IRQ. The patch ensures that smc_phy_configure always exits with register bank 2 selected.

| | | | | | | | | | | | | Not only SMC_ACK_INT(IM_TX_EMPTY_INT) in in smc_hardware_send_pkt) appears to be unnecessary (tested with an SMC91C94 and SMC91C111), but it seems to trigger spurious interrupts on some machines as well. Removed. While at it, let's log any remaining spurious interrupts if any (and clean usage of the max IRQ loop count value).

| * [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.

* [PATCH] smc91x needs settable IRQ trigger typeDavid Brownell2005-06-27
| | | | | | | | | For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it), the set_irq_type() call can't assume IRQT_RISING. These particular boards currently use OMAP-specific calls to change the trigger type, but the boards break when set_irq_type() stops being a NOP.

* [PATCH] smc91x: plug race between TX tasklet and driver resetNicolas Pitre2005-06-27
| | | | | | | | | The race causes a kernel oops when smc_hardware_send_pkt() tries to dereference pending_tx_skb which would have been freed from one of the driver reset paths just after the tx_task tasklet has been scheduled.

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!
