* ieee1394: ohci1394: don't schedule IT tasklets on IR eventsStefan Richter2008-01-30
| | | | | | | | | | Bug noted by Pieter Palmers: Isochronous transmit tasklets were scheduled on isochronous receive events, in addition to the proper isochronous receive tasklets. http://marc.info/?l=linux1394-devel&m=119783196222802 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* ieee1394: ohci1394: fix initialization if built non-modularStefan Richter2007-09-20
| | | | | | | | | | | | | | | | Initialization of ohci1394 was broken according to one reporter if the driver was statically linked, i.e. not built as loadable module. Dmesg: PCI: Device 0000:02:07.0 not available because of resource collisions ohci1394: Failed to enable OHCI hardware. This was reported for a Toshiba Satellite 5100-503. The cause is commit 8df4083c5291b3647e0381d3c69ab2196f5dd3b7 in Linux 2.6.19-rc1 which only served purposes of early remote debugging via FireWire. This functionality is better provided by the currently out-of-tree driver ohci1394_earlyinit. Reversal of the commit was OK'd by Andi Kleen. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* ieee1394: remove old isochronous ABIStefan Richter2007-07-09
| | | | | | | | | | | | | | | | | | | Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | 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).

* ohci1394: steps to implement suspend/resumeBernhard Kaindl2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I did a quick shot on what I described and the appended patch does the first thing needed for working suspend/resume in ohci1394 which is HW de- and re-initialisation. It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller with the 2.6.17 kernel to the extent that if I call dvgrab --interactive after suspend2disk without unloading ohci1394, it does not lock up dvgrab with 100% CPU but properly connects to the camera, given that I first unplug and plug the camera after coming back from suspend. I guess that could be fixed by forcing a bus reset in the resume function. I cannot test suspend to RAM here at the moment and should follow the guidelines in Documentation/power/pci.txt also, so this is rather a quick report than a finished patch and there are some rough edges: However, with this patch, I have to unload at least some in-kernel users of ohci1394 like dv1394 or video1394 before suspending. Not doing that caused an Oops and a bad tasklet error, probably from not handling ISO tasklets during suspend/resume properly. Maybe these can be temporarily cleared or unregistered and re-registered for suspend/resume with help from the other layers or from the highlevel 1394 core, but I do not really know what these do. But this patch provides a useful base to start from and is already of much help for people which do not need dv1394 and video1394 or can unload them at least during suspend. I cannot test function with sbp2 at the moment, but raw1394 seems to work fine.

* 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.

| * Fix broken suspend/resume in ohci1394Ben Collins2006-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've been experimenting to track down the cause of suspend/resume problems on my Compaq Presario X1050 laptop: http://bugzilla.kernel.org/show_bug.cgi?id=6075 Essentially the ACPI Embedded Controller and keyboard controller would get into a bizarre, confused state after resume. I found that unloading the ohci1394 module before suspend and reloading it after resume made the problem go away. Diffing the dmesg output from resume, with and without the module loaded, I found that with the module loaded I was missing these: PM: Writing back config space on device 0000:02:00.0 at offset 1. (Was 2100080, writing 2100007) PM: Writing back config space on device 0000:02:00.0 at offset 3. (Was 0, writing 8008) PM: Writing back config space on device 0000:02:00.0 at offset 4.

(Was 20000100, writing 2000010a) The default PCI driver performs the pci_restore_state when no driver is loaded for the device. When the ohci1394 driver is loaded, it is supposed to do this, however it appears not to do so. I created the patch below and tested it, and it appears to resolve the suspend problems I was having with the module loaded. I only added in the pci_save_state and pci_restore_state - however, though I know little of this hardware, surely the driver should really be doing more than this when suspending and resuming? Currently it does almost nothing, what if there are commands in progress, etc?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch supplies the API extension introduced by patch "ieee1394: extend lowlevel API for address range properties" with proper addresses. Like in patch ''ohci1394, sbp2: fix "scsi_add_device failed" with PL-3507 based devices'', 1 TeraByte is chosen as physical upper bound. This leaves a window for the middle address range. This choice is only relevant for adapters which actually have a programmable pysical upper bound register. (Only ALi and Fujitsu adapters are known for this. Most adapters have a fixed bound at 4 GB.) The middle address range is suitable for posted writes. AFAIK, PCILynx does not support physical DMA nor posted writes, therefore no equivalent change in the pcilynx driver is necessary. There is also a driver for GP2Lynx, although not in mainline Linux. I assume this hardware does not support these OHCI features either. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Ben Collins <bcollins@ubuntu.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the ohci1394.c file to enable and manage the "cycle too long" interrupt. If this interrupt occurs, the "LinkControl.CycleMaster" bit of the host controller is reseted. This implies, that the host controller does not send "cycle start" packet anymore freezing then the isochronous communication. The management of the interrupt added by the patch is that when the interrupt occurs, the OHCI irq handler prints a kernel log warning and then sets the "LinkControl.CycleMaster" bit again resuming the isochronous communication.

* | [SPARC]: Kill __irq_itoa().David S. Miller2006-06-20
|/ | | | | | | | | | | | | | | | | | This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] ohci1394, sbp2: fix "scsi_add_device failed" with PL-3507 based devicesStefan Richter2006-05-18
| | | | | | | | | | | | | | | Re-enable posted writes for status FIFO. Besides bringing back a very minor bandwidth tweak from Linux 2.6.15.x and older, this also fixes an interoperability regression since 2.6.16: http://bugzilla.kernel.org/show_bug.cgi?id=6356 (sbp2: scsi_add_device failed. IEEE1394 HD is not working anymore.)

| * [PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt2006-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

* | ohci1394: cleanup the "Unexpected PCI resource length" warning.Jody McIntyre2006-03-28
| | | | | | | | | | | | | | | | | | | | This warning happens in practice because the resource length reported by the chipset is too large. This is not actually a problem, so don't warn about it. If it happens to be too small, warn about that, but with a different message so people who are used to ignoring the old message don't. Signed-off-by: Jody McIntyre <scjody@modernduck.com>
* | ohci1394: clean up asynchronous and physical request filters programmingStefan Richter2006-03-28
| | | | | | | | | | | | | | | | | | | | Various cleanups of how ohci1394 programs AsynchronousRequestFilter, PhysicalRequestFilter, and physUpperBoundOffset. In particular, do not rewrite registers within the bus reset interrupt handler if bus resets do not affect the registers in the first place.
