2015-11-19Bluetooth: Use new hci_skb_pkt_* wrappers for driversMarcel Holtmann1-5/+6
The new hci_skb_pkt_* wrappers are mainly intented for drivers to require less knowledge about bt_cb(sbk) handling. So after converting the core packet handling, convert all drivers. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-10-05Bluetooth: Move handling of HCI_RUNNING flag into coreMarcel Holtmann1-6/+0
Setting and clearing of HCI_RUNNING flag in each and every driver is just duplicating the same code all over the place. So instead of having the driver do it in their hdev->open and hdev->close callbacks, set it globally in the core transport handling.

2014-08-14Bluetooth: Remove typedef btuart_info_tHimangi Saraogi1-13/+14
The Linux kernel coding style guidelines suggest not using typedefs for structure types. This patch gets rid of the typedef for btuart_info_t. Also, the name of the struct is changed to drop the _t, to make the name look less typedef-like. The following Coccinelle semantic patch detects the case: @tn@ identifier i; type td; @@ -typedef struct i { ... } -td ; @@ type tn.td; identifier tn.i; @@ -td + struct i Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2013-10-11Bluetooth: Add hdev parameter to hdev->send driver callbackMarcel Holtmann1-2/+1
Instead of masking hdev inside the skb->dev parameter, hand it directly to the driver as a parameter to hdev->send. This makes the driver interface more clear and simpler. This patch fixes all drivers to accept and handle the new parameter of hdev->send callback. Special care has been taken for bpa10x and btusb drivers that require having skb->dev set to hdev for the URB transmit complete handlers.

2012-02-13Bluetooth: Remove HCI-owner fieldDavid Herrmann1-2/+0
After unregistering an hci_dev object a bluetooth driver does not have any callbacks in the hci_dev structure left over. Therefore, there is no need to keep a reference to the module. Previously, we needed this to protect the hci-destruct callback. However, this callback is no longer available so we do not need this owner field, anymore. Drivers now call hci_unregister_dev() and they are done with the object.

IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO (all other drivers). As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

Instead of the old pcmcia_request_irq() interface, drivers may now choose between: - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq. - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will clean up automatically on calls to pcmcia_disable_device() or device ejection. - drivers still not capable of IRQF_SHARED (or not telling us so) may use the deprecated pcmcia_request_exclusive_irq() for the time being; they might receive a shared IRQ nonetheless.

2009-11-28pcmcia: rework the irq_req_t typedefDominik Brodowski1-3/+1
Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-1/+1
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.
