2007-04-27PNP: stop using the subsystem rwsemGreg Kroah-Hartman
The rwsem is not used to protect anything, so the use of it by the PNP subsystem isn't really useful, and it's doubtful if it really did anything or not. So I've removed it. Cc: Adam Belay <ambx1@neo.rr.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-02-11[PATCH] PNP: export pnp_bus_typeDavid Brownell
The PNP framework doesn't export "pnp_bus_type", which is an unfortunate exception to the policy followed by pretty much every other bus. I noticed this when I had to find a device in order to provide its platform_data. Note that per advice from Arjan, the "export" scope has been been minimized to avoid the hundred-plus bytes needed to support access from modules. In this case, the symbol is only needed by statically linked kernel code that lives outside the drivers/pnp directory.

2006-10-18Fix DMA resource allocation in ACPIPnPVojtech Pavlik
The ACPIPnP implementation had the understanding of Linux resource flags very wrong, resulting in a nonfunctional implementation of DMA resource allocation. This was usually not a problem, since almost no on-board PnP devices use ISA DMA, with the exception of ECP parallel ports. Even with that, parallel port DMA is preconfigured by the BIOS, so this routine isn't normally called. Except in the case where somebody does 'rmmod parport_pc; modprobe parport_pc', where the rmmod case disables the ECP parallel port resources, and they need to be enabled again to initialize the module. This didn't work, resulting in a non-printing printer. The application doing exactly the above to force reprobing of printers is the YaST printer module. Thus without this fix YaST wedged the printer when configuring it, and was not able to print a test page.

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.

2006-08-06[PATCH] pnpacpi: reject ACPI_PRODUCER resourcesmatthieu castet
A patch in -mm kernel correct the parsing of "address resources" of pnpacpi. Before we assumed it was memory only, but it could be also IO. But this change show an hidden bug : some resources could be producer type that are not handled by pnp layer. So we should ignore the producer resources. This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292). Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer resources. Before correcting "address resources" parsing, it was seen as memory and was harmless, because nobody tried to reserve this memory range as it should be IO. With the correction it become IO resources, and make failed all others device that want to register IO in this range and use pnp layer (like a ISA sound card). The solution is to ignore producer resources Signed-off-by: Matthieu CASTET <castet.matthieu@free.fr> Signed-off-by: Uwe Bugla <uwe.bugla@gmx.de> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Adam Belay <ambx1@neo.rr.com> Cc: "Brown, Len" <len.brown@intel.com> Acked-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-31[PATCH] Fix swsusp with PNP BIOSOndrej Zary
swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse). The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the device if the device can be disabled according to pnp_can_disable(). The problem is that pnpbios_disable_resources() returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets PNP_DISABLE capability/flag even if the device is not dynamic. So we try to disable non-dynamic devices which will fail. This patch prevents insert_device() from setting PNP_DISABLE if the device is not dynamic and fixes suspend on my system.

2006-03-25[PATCH] Fix memory leak in isapnpJesper Juhl
Spotted by the Coverity checker as bug #666 akpm; there are several other `return 1;'s in there which aren't freeing `dev'. (A fix which converts this function to single-exit would be preferred..)

Without the attached, the kernel complains about my BIOS' PNP tables.

2006-02-28[PATCH] pnp bus type fixAdam Belay
This is Adam's pnp probing fix. It's been reported to fix hangs on several people's machines. I don't know if it's official or final, and Adam isn't contactable at present. But I'm not aware of the patch causing any regressions. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-01-20[ACPI] better fix for pnpacpi regression resulting from ACPICA 20051117Len Brown
Rather than tweaking acpi_walk_resource() again not return end tags, modify the pnpacpi code to ignore them. The pnpacpi resource type switch statements now include all known types in the order that they're defined -- so it is easy to see what is not implemented. The code will squawk only if it sees a truly undefined type. Signed-off-by: Len Brown <len.brown@intel.com>
