2011-10-18parport_pc: release IO region properly if unsupported ITE887x card is foundJiri Kosina1-0/+3
sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or unknown card. It doesn't call release_region() on the previously allocated resource though. This causes (a) leak of the resource (b) kernel oops when parport module is removed and /proc/ioports is read. This is because the string that has been associated to the IO port region is a static char array inside the already removed module. Let's call release_region() properly before baling out.

2011-06-07parport/serial: add support for Timedia/SUNIX cards to parport_serialFrédéric Brière1-54/+0
Timedia/SUNIX PCI cards with both serial and parallel ports are currently supported by 8250_pci and parport_pc individually. Moving that support into parport_serial allows using both types of ports at the same time. This was successfully tested with a SUNIX 4079T.

2009-06-22parport_pc: set properly the dma_mask for parport_pc deviceFUJITA Tomonori1-0/+3
parport_pc_probe_port() creates the own 'parport_pc' device if the device argument is NULL. Then parport_pc_probe_port() doesn't initialize the dma_mask and coherent_dma_mask of the device and calls dma_alloc_coherent with it. dma_alloc_coherent fails because dma_alloc_coherent() doesn't accept the uninitialized dma_mask: http://lkml.org/lkml/2009/6/16/150 Long ago, X86_32 and X86_64 had the own dma_alloc_coherent implementations; X86_32 accepted a device having dma_mask that is not initialized however X86_64 didn't. When we merged them, we chose to prohibit a device having dma_mask that is not initialized. I think that it's good to require drivers to set up dma_mask (and coherent_dma_mask) properly if the drivers want DMA.

2009-06-22parport_pc: after superio probing restore original register valuesJens Rottmann1-6/+25
CONFIG_PARPORT_PC_SUPERIO probes for various superio chips by writing byte sequences to a set of different potential I/O ranges. But the probed ranges are not exclusive to parallel ports. Some of our boards just happen to have a watchdog in one of them. Took us almost a week to figure out why some distros reboot without warning after running flawlessly for 3 hours. For exactly 170 = 0xAA minutes, that is ... Fixed by restoring original values after probing. Also fixed too small request_region() in detect_and_report_it87().

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-2/+2
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.

2006-10-03[PATCH] restore parport_pc probing on powermacOlaf Hering1-4/+0
The last change for partport_pc did fix the common case for all PowerMacs, but it broke the case for PCI multiport IO cards. In fact, the config option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed the parport driver. It enables the winbond and smsc probing. Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will take care of it. All powerpc configs should have CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp boards we tested it on.

2006-10-01[PATCH] update legacy io handling for pmacOlaf Hering1-0/+4
ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can boot one single binary on pseries and G5 boards. pmac has no legacy io, probing for PC style legacy hardware (or accessing the legacy io area regulary) may lead to a hard crash: * add check for parport_pc, exit on pmac. 32bit chrp has no ->check_legacy_ioport, the probe is always called. 64bit chrp has check_legacy_ioport, check for a "parallel" node * add check for isapnp, only PReP boards may have real ISA slots. 32bit PReP will have no ->check_legacy_ioport, the probe is always called. * update code in i8042_platform_init. Run ->check_legacy_ioport first, always call request_region. No functional change. Remove whitespace before i8042_reset init.

Remove the assumption that pnp_register_driver() returns the number of devices claimed. parport_pc_init() does nothing with "count", so remove it. Then nobody uses the return value of parport_pc_find_ports(), so make it void. Finally, update pnp_register_driver() usage.

2005-07-01[PATCH] PCI: clean up dynamic pci id logicGreg Kroah-Hartman1-1/+1
The dynamic pci id logic has been bothering me for a while, and now that I started to look into how to move some of this to the driver core, I thought it was time to clean it all up. It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.

kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo controller cards. this implementation doesn't work for nm9855 based cards! there are two reasons: a) the module 'parport_pc' doesn't want to give the resonsibility for the netmos_9855 to 'parport_serial' and can not handle the serial lines -- trivial to fix... http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in 'parport_serial' still doesn't work because of wrong assumptions about the relevant BARs port address layout for this chip: 0000:00:09.0 Communication controller: NetMos Technology PCI 9855 Multi-I/O Controller (rev 01) (= 9710:9855) Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014) Flags: medium devsel, IRQ 177 I/O ports at a800 [size=8] (= parport) I/O ports at a400 [size=8] I/O ports at a000 [size=8] (= serial) I/O ports at 9800 [size=8] (= serial) I/O ports at 9400 [size=8] (= serial) I/O ports at 9000 [size=16] (= serial) the following patch will fix the problem.

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!
