* [PATCH] PNP: export pnp_bus_typeDavid Brownell2007-02-11
| | | | | | | | | | | | | | | | 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.

* Fix DMA resource allocation in ACPIPnPVojtech Pavlik2006-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

* [PATCH] pnpacpi: reject ACPI_PRODUCER resourcesmatthieu castet2006-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* [PATCH] Fix swsusp with PNP BIOSOndrej Zary2006-07-31
| | | | | | | | | | | | | | | | | | | | | 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.

| | | * | [ACPI] better fix for pnpacpi regression resulting from ACPICA 20051117Len Brown2006-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | * [ACPI] enable PNPACPI support for resource types used by HP serial portsBjorn Helgaas2006-01-07

HP firmware uses them for built-in serial ports, so this patch adds support for parsing these descriptors from _PRS. Note that this does not add the corresponding support for encoding them in preparation for _SRS, because I don't have any machine that supports _SRS on these descriptors, so I couldn't test that support. Attempts to encode them will cause a warning and an -EINVAL return. http://sourceforge.net/mailarchive/forum.php?thread_id=8250154&forum_id=6102 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>

This essentially entails recognizing that these processors support non-aligned memory transfers. Previously, all 64-bit processors were assumed to lack hardware support for non-aligned transfers. Completed conversion of the Resource Manager to nearly full table-driven operation. Specifically, the resource conversion code (convert AML to internal format and the reverse) and the debug code to dump internal resource descriptors are fully table-driven, reducing code and data size and improving maintainability. The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word on 64-bit processors instead of a fixed 32-bit word. (Alexey Starikovskiy) Implemented support within the resource conversion code for the Type-Specific byte within the various ACPI 3.0 *WordSpace macros. Fixed some issues within the resource conversion code for the type-specific flags for both Memory and I/O address resource descriptors. For Memory, implemented support for the MTP and TTP flags. For I/O, split the TRS and TTP flags into two separate fields. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate(). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PnP BIOS data, code, and 32-bit entry segments all have fixed limits as well; set them in the GDT rather than adding more code. It would be nice to add these fixups to the boot GDT rather than setting the GDT for each CPU; perhaps I can wiggle this in later, but getting it in before the subsys init looks tricky. Also, make some progress on deprecating the ugly Q_SET_SEL macros.
