* x86: Move pci init function to x86_initThomas Gleixner2010-02-201-4/+2Star
| | | | | | | | | | | | | | | | | | | | | The PCI initialization in pci_subsys_init() is a mess. pci_numaq_init, pci_acpi_init, pci_visws_init and pci_legacy_init are called and each implementation checks and eventually modifies the global variable pcibios_scanned. x86_init functions allow us to do this more elegant. The pci.init function pointer is preset to pci_legacy_init. numaq, acpi and visws can modify the pointer in their early setup functions. The functions return 0 when they did the full initialization including bus scan. A non zero return value indicates that pci_legacy_init needs to be called either because the selected function failed or wants the generic bus scan in pci_legacy_init to happen (e.g. visws).

* x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.hJaswinder Singh Rajput2008-12-291-2/+1Star
| | | | | | | | | | | | | | | Impact: cleanup Now that arch/x86/pci/pci.h is used in a number of other places as well, move the lowlevel x86 pci definitions into the architecture include files. (not to be confused with the existing arch/x86/include/asm/pci.h file, which provides public details about x86 PCI) Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/pci: Changing subsystem init for viswsRobert Richter2008-07-111-16/+7Star
| | | | | | | | | I don't know, if this new code boots, but at least it compiles. Someone should really test it. Signed-off-by: Robert Richter <robert.richter@amd.com> Cc: Robert Richter <robert.richter@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, VisWS: turn into generic arch, create include/asm-x86/visws/Ingo Molnar2008-07-101-2/+2
| | | | | | | | | | move the include/asm-x86/mach-visws/ VISWS specific hardware details include files into include/asm-x86/visws, to be used from generic code. No code changed. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86, VisWS: turn into generic arch, add early init quirksIngo Molnar2008-07-101-0/+4
| | | | | | | add early init quirks for VisWS. This gradually turns the VISWS subarch into a generic PC architecture. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, VisWS: turn into generic arch, make VisWS boot on a regular PCIngo Molnar2008-07-101-3/+3
| | | | | | | | | | | first step: make the VISWS subarch boot on a regular PC. We take various shortcuts for that. We copy the generic arch setup file over into the VISWS setup file. This is the only step that is not expected to boot on a real VISWS. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/pci: removing subsys_initcall ordering dependenciesRobert Richter2008-07-091-1/+6
| | | | | | | | | | | | | | | | | | | | So far subsys_initcalls has been executed in this order depending on the object order in the Makefile: arch/x86/pci/visws.c:subsys_initcall(pcibios_init); arch/x86/pci/numa.c:subsys_initcall(pci_numa_init); arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init); arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init); arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init); arch/x86/pci/common.c:subsys_initcall(pcibios_init); This patch removes the ordering dependency. There is now only one subsys_initcall function that contains subsystem initialization code with a defined order.

* Change pci_raw_ops to pci_raw_read/writeMatthew Wilcox2008-02-101-3/+0Star
| | | | | | | | | | We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write().
