* [IA64] Fix pcibios_setupMatthew Wilcox2006-02-271-1/+1
| | | | | | | | | | pcibios_setup() should return NULL if it handled a parameter. Since ia64 handles no parameters, it should return the string that was passed in, not NULL. This brings ia64 into line with all other architectures that handle no parameters. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Tony Luck <tony.luck@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>

* | [IA64] incorrect return from ia64_pci_legacy_write()Alex Williamson2006-01-031-1/+1
|/ | | | | | | | | | | The function ia64_pci_legacy_write() returns 0 for everything except errors. This return value gets sent back to the user from pci_write_legacy_io(), making it look like every write fails. The trivial patch below copies the behavior of the SGI sn machvec and does what would be expected from something implementing a write() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Address space resources for ACPI devices have a producer/consumer flag. All devices "consume" the indicated address space. If the resource is marked as a "producer", the range is also passed on to child devices. We currently ignore this flag when setting up MMIO and I/O port windows for PCI root bridges, so we could mistakenly interpret a "consumed-only" range, like CSR space for the device itself, as a window that is routed to children.

* [IA64] pcibus_to_node implementation for IA64Christoph Lameter2005-07-121-2/+10
| | | | | | | | | | | | | | pcibus_to_node provides a way for the Linux kernel to identify to which node a certain pcibus connects to. Allocations of control structures for devices can then be made on the node where the pci bus is located to allow local access during interrupt and other device manipulation. This patch provides a new "node" field in the the pci_controller structure. The node field will be set based on ACPI information (thanks to Alex Williamson <alex.williamson@hp.com for that piece).

* [PATCH] acpi bridge hotadd: Make pcibios_fixup_bus() hot-plug safeRajesh Shah2005-06-271-1/+21
| | | | | | | | | | | | | | PCI scan code calls the arch specific pcibios_fixup_bus() each time it scans a new bridge. For root bridge hot-plug, the bridge and it's attached devices may not have been configured properly yet, so it's not safe to claim those resources at this time. This code goes away when we clean up the way pci resources are claimed (in pci_enable_device()), so this is only a stopgap fix.

| | | | | | | | | | | | When checking if a PCI to PCI bridge should be enabled to decode memory and/or IO resources, we need to look at all device resources not just the first 6. This is needed to allow PCI bridges to pass down memory and IO accesses to child devices even when the bridge itself does not consume resources in its PCI BARs.

* [PATCH] acpi bridge hotadd: ACPI based root bridge hot-addRajesh Shah2005-06-271-1/+1
| | | | | | | | | | | | | | | | | | | When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and devices attached to it that have not been configured by firmware. In this case, we need to configure the devices before starting them. This patch separates device start from device scan so that we can introduce the configuration step in the middle. I kept the existing semantics for pci_scan_bus() since there are a huge number of callers to that function. Also, I have no way of testing the changes I made to the parisc files, so this needs review by those folks. Sorry for the massive cross-post, this touches files in many different places.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-162-0/+739
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!
