2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
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).

2007-02-12[PATCH] mark struct file_operations const 5Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-10[SPARC64]: Add PCI MSI support on Niagara.David S. Miller
This is kind of hokey, we could use the hardware provided facilities much better. MSIs are assosciated with MSI Queues. MSI Queues generate interrupts when any MSI assosciated with it is signalled. This suggests a two-tiered IRQ dispatch scheme: MSI Queue interrupt --> queue interrupt handler MSI dispatch --> driver interrupt handler But we just get one-level under Linux currently. What I'd like to do is possibly stick the IRQ actions into a per-MSI-Queue data structure, and dispatch them form there, but the generic IRQ layer doesn't provide a way to do that right now. So, the current kludge is to "ACK" the interrupt by processing the MSI Queue data structures and ACK'ing them, then we run the actual handler like normal. We are wasting a lot of useful information, for example the MSI data and address are provided with ever MSI, as well as a system tick if available. If we could pass this into the IRQ handler it could help with certain things, in particular for PCI-Express error messages. The MSI entries on sparc64 also tell you exactly which bus/device/fn sent the MSI, which would be great for error handling when no registered IRQ handler can service the interrupt. We override the disable/enable IRQ chip methods in sun4v_msi, so we have to call {mask,unmask}_msi_irq() directly from there. This is another ugly wart. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-02-09devres: device resource managementTejun Heo
Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-07msi: Make MSI useable more architecturesEric W. Biederman
The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now responsible for allocating and freeing the linux irq in addition to setting up the the linux irq to work with the interrupt. arch_setup_msi_irq now takes a pci_device and a msi_desc and returns an irq. With this change in place this code should be useable by all platforms except those that won't let the OS touch the hardware like ppc RTAS. Signed-off-by: Eric W.

2007-02-07msi: Kill the msi_desc array.Eric W. Biederman
We need to be able to get from an irq number to a struct msi_desc. The msi_desc array in msi.c had several short comings the big one was that it could not be used outside of msi.c. Using irq_data in struct irq_desc almost worked except on some architectures irq_data needs to be used for something else. So this patch adds a msi_desc pointer to irq_desc, adds the appropriate wrappers and changes all of the msi code to use them. The dynamic_irq_init/cleanup code was tweaked to ensure the new field is left in a well defined state. Signed-off-by: Eric W.

2007-02-07msi: Remove msi_lock.Eric W. Biederman
With the removal of msi_lookup_irq all of the functions using msi_lock operated on a single device and none of them could reasonably be called on that device at the same time. Since what little synchronization that needs to happen needs to happen outside of the msi functions, msi_lock could never be contended and as such is useless and just complicates the code.

2007-02-07msi: Kill msi_lookup_irqEric W. Biederman
The function msi_lookup_irq was horrible. As a side effect of running it changed dev->irq, and then the callers would need to change it back. In addition it does a global scan through all of the irqs, which seems to be the sole justification of the msi_lock. To remove the neede for msi_lookup_irq I added first_msi_irq to struct pci_dev. Then depending on the context I replaced msi_lookup_irq with dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled. msi_enabled and msix_enabled were already present in pci_dev for other reasons.

2007-02-07MSI: Combine pci_(save|restore)_msi/msix_stateMichael Ellerman
The PCI save/restore code doesn't need to care about MSI vs MSI-X, all it really wants is to say "save/restore all MSI(-X) info for this device". This is borne out in the code, we call the MSI and MSI-X save routines side by side, and similarly with the restore routines. So combine the MSI/MSI-X routines into pci_save_msi_state() and pci_restore_msi_state(). It is up to those routines to decide what state needs to be saved.

2007-02-07MSI: Replace pci_msi_quirk with calls to pci_no_msi()Michael Ellerman
I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature.

2007-02-07PCI Quirk: 1k I/O space IOBL_ADR fix on P64H2Daniel Yeisley
There's an existing quirk for the kernel to use 1k IO space granularity on the Intel P64H2. It turns out however that pci_setup_bridge() in drivers/pci/setup-bus.c reads in the IO base and limit address register masks it off to the nearest 4k, and writes it back. This causes the kernel to be on 1k boundaries and the hardware to be 4k aligned. The patch below fixes the problem.

2007-02-07ide: add Toshiba TC86C001 IDE driver (take 2)Sergei Shtylyov
This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller, completely reworked from the original brain-damaged Toshiba's 2.4 version. This single channel UltraDMA/66 controller is very simple in programming, yet Toshiba managed to plant many interesting bugs in it. The particularly nasty "limitation 5" (as they call the errata) caused me to abuse the IDE core in a possibly most interesting way so far. However, this is still better than the #ifdef mess in drivers/ide/ide-io.c that the original version included (well, it had much more mess)...

2007-02-02Altix: Add ACPI SSDT PCI device support (hotplug)John Keller
Support for dynamic loading and unloading of ACPI SSDT tables upon slot hotplugs and unplugs. On SN platforms, we now represent every populated root bus slot with a single ACPI SSDT table containing info for every device and PPB attached to the slot. These SSDTs are generated by the prom at initial boot and hotplug time. The info in these SSDT tables is used by the SN kernel IO "fixup" code (which is called at boot and hotplug time). On hotplugs (i.e. enable_slot()), if running with an ACPI capable prom, attempt to obtain a new ACPI SSDT table for the slot being hotplugged. If successful, add the table to the ACPI namespace (acpi_load_table()) and then walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()). On hot unplugs (i.e. disable_slot()), if running with an ACPI capable prom, attempt to remove the SSDT table associated with the slot from the ACPI namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()). From: John Keller <jpk@sgi.com> A bug was fixed where the sgi hotplug driver was removing the slot's SSDT table from the ACPI namespace a bit too early in disable_slot(). Also, we now call acpi_bus_start() subsequent to acpi_bus_add().

2007-02-02ahci/pata_jmicron: fix JMicron quirkTejun Heo
For all JMicrons except for 361 and 368, AHCI mode enable bits in the Control(1) should be set. This used to be done in both ahci and pata_jmicron but while moving programming to PCI quirk, it was removed from ahci part while still left in pata_jmicron. The implemented JMicron PCI quirk was incorrect in that it didn't program AHCI mode enable bits. If pata_jmicron is loaded first and programs those bits, the ahci ports work; otherwise, ahci device detection fails miserably. This patch makes JMicron PCI quirk clear SATA IDE mode bits and set AHCI mode bits and remove the respective part from pata_jmicron. Tested on JMB361, 363 and 368.

2007-02-01[PATCH] pci: remove warning messagesAndrew Morton
Remove these recently-added warnings. They don't tell us anythng very interesting and Kumar says "On an embedded PPC reference system I see this message 6 times when I've got no cards in the PCI slots."
