2010-12-24usb: don't use flush_scheduled_work()Tejun Heo
flush_scheduled_work() is being deprecated. Directly flush or cancel work items instead. * u_ether, isp1301_omap, speedtch conversions are straight-forward. * ochi-hcd should only flush when quirk_nec() is true as otherwise the work wouldn't have been initialized. * In oti6858, cancel_delayed_work() + flush_scheduled_work() -> cancel_delayed_work_sync().

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

This patch (as1150) fixes a problem in the speedtch driver. When it resets the modem during probe it will be unbound from the other interfaces it has claimed, because it doesn't define a pre_reset and a post_reset method.

2006-10-17speedtch: "extended reach"Duncan Sands
The speedtouch modem setup code was reverse engineered many years ago from a prehistoric windows driver. Less ancient windows drivers, even those from a few years ago, perform extra initialization steps which this patch adds to the linux driver. David Woodhouse observed that this initialization along with the firmware bin/sachu3/zzzlp2.eni from the driver at http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip improves line sync speeds by about 20%. He provided the original patch, which I've modified to use symbolic names (BMaxDSL, ModemMode, ModemOption) rather than magic numbers. These names may not seem like much of an improvement (after all, what is "ModemOption" exactly?), but they do have one big advantage: they are the names used in the windows registry. I've made them available as module parameters. Thanks are due to Aurelio Arroyo, who noticed the relationship between these magic numbers and the entries in Phonebook.ini.

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.

2006-05-09[PATCH] USBATM: change the default speedtouch iso altsettingDuncan Sands
The maximum possible bandwidth for a speedtouch modem is about 7Mbaud. You can only get this by using isochronous urbs (enable_isoc=1) and altsetting 3. With the current default altsetting of 2, the modem maxes out at about 4Mbaud. So change the default altsetting to 3 when using isochronous urbs. It would be nice to base the altsetting on the detected line speed, but that's hard given the current design.

2006-02-01[PATCH] USBATM: allow isochronous transferDuncan Sands
While the usbatm core has had some support for using isoc urbs for some time, there was no way for users to turn it on. While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

2006-02-01[PATCH] USBATM: measure buffer size in bytes; force valid sizesDuncan Sands
Change the module parameters rcv_buf_size and snd_buf_size to specify buffer sizes in bytes rather than ATM cells. Since there is some danger that users may not notice this change, the parameters are renamed to rcv_buf_bytes etc. The transmit buffer needs to be a multiple of the ATM cell size in length, while the receive buffer should be a multiple of the endpoint maxpacket size (this wasn't enforced before, which causes trouble with isochronous transfers), so enforce these restrictions. Now that the usbatm probe method inspects the endpoint maxpacket size, minidriver bind routines need to set the correct alternate setting for the interface in their bind routine. This is the reason for the speedtch changes. Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-07-12[PATCH] USB ATM: fix line resync logicDuncan Sands
We map states 0x00 and 0x10 to the ATM_PHY_SIG_LOST flag. The current logic fails to resync the line if we get state 0x10 followed by 0x00, since we only resync the line when the state is 0x00 and the flag changed. Doubly fixed by (1) always resyncing the line when the state is 0x00 even if the state didn't change, and (2) keeping track of the last state, not just the flag. We do (2) as well as (1) in order to get better log messages. This is a tweaked version of the original patch by Aurelio Arroyo.
