On some boxes there exist both RSDT and XSDT table. But unfortunately sometimes there exists the following error when XSDT table is used: a. 32/64X address mismatch b. The 32/64X FACS address mismatch In such case the boot option of "acpi=rsdt" is provided so that RSDT is tried instead of XSDT table when the system can't work well. http://bugzilla.kernel.org/show_bug.cgi?id=8246 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> cc:Thomas Renninger <trenn@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

2009-01-07ACPI/PCI: PCI MSI _OSC support capabilities called when root bridge addedAndrew Patterson1-0/+2
The _OSC capability OSC_MSI_SUPPORT is set when the root bridge is added with pci_acpi_osc_support(), so we no longer need to do it in the PCI MSI driver. Also adds the function pci_msi_enabled, which returns true if pci=nomsi is not on the kernel command-line.

2009-01-07ACPI/PCI: PCIe ASPM _OSC support capabilities called when root bridge addedAndrew Patterson1-0/+3
The _OSC capabilities OSC_ACTIVE_STATE_PWR_SUPPORT and OSC_CLOCK_PWR_CAPABILITY_SUPPORT are set when the root bridge is added with pci_acpi_osc_support(), so we no longer need to do it in the ASPM driver. Also add the function pcie_aspm_enabled, which returns true if pcie_aspm=off is not on the kernel command-line.

2009-01-07ACPI/PCI: PCI extended config _OSC support called when root bridge addedAndrew Patterson1-2/+8
The _OSC capability OSC_EXT_PCI_CONFIG_SUPPORT is set when the root bridge is added with pci_acpi_osc_support() if we can access PCI extended config space. This adds the function pci_ext_cfg_avail which returns true if we can access PCI extended config space (offset greater than 0xff). It currently only returns false if arch=x86 and raw_pci_ext_ops is not set (which might happen if pci=nommcfg is set on the kernel command-line).

2009-01-07ACPI/PCI: call _OSC support during root bridge discoveryAndrew Patterson1-0/+9

2009-01-06remove linux/hardirq.h from asm-generic/local.hRussell King1-0/+1
While looking at reducing the amount of architecture namespace pollution in the generic kernel, I found that asm/irq.h is included in the vast majority of compilations on ARM (around 650 files.) Since asm/irq.h includes a sub-architecture include file on ARM, this causes a negative impact on the ccache's ability to re-use the build results from other sub-architectures, so we have a desire to reduce the dependencies on asm/irq.h. It turns out that a major cause of this is the needless include of linux/hardirq.h into asm-generic/local.h. The patch below removes this include, resulting in some 250 to 300 files (around half) of the kernel then omitting asm/irq.h. My test builds still succeed, provided two ARM files are fixed (arch/arm/kernel/traps.c and arch/arm/mm/fault.c) - so there may be negative impacts for this on other architectures. Note that x86 does not include asm/irq.h nor linux/hardirq.h in its asm/local.h, so this patch can be viewed as bringing the generic version into line with the x86 version.

2009-01-03cpumask: convert shared_cpu_map in acpi_processor* structs to cpumask_var_tRusty Russell3-44/+78
Impact: Reduce memory usage, use new API. This is part of an effort to reduce structure sizes for machines configured with large NR_CPUS. cpumask_t gets replaced by cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or struct cpumask * (large NR_CPUS).

2008-12-31ACPICA: FADT: set acpi_gbl_use_default_register_widths to TRUE by defaultrobert.moore@intel.com1-68/+105
This returns the FADT support to the original behavior, which is to use default register widths. However, now check each register definition and report a warning if it differs from the default. This is a first step to moving away from the default widths, rather than outright believing the widths in all FADTs for all machines, considered rather dangerous until more data is obtained.

2008-12-31ACPICA: FADT parsing changes and fixesBob Moore1-20/+105
1) Update the register lengths for the PM1 event blocks. The length must be divided by two in order to use these to access the status registers. 2) Add run-time option to use default register lengths to override a faulty FADT. 3) Add warning message if any of the X64 address structures contain a length that does not match the legacy length earlier in the FADT. 4) Move all FADT warning messages into the ValidateFadt function.

acpi.h now includes only the "public" acpica headers. All other acpica headers are "private" and should not be included by acpica users.

Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to the public acpi_read and acpi_write to allow direct access to ACPI registers. Removed the "width" parameter since the width can be obtained from the input GAS structure. Updated the FADT initialization to setup the GAS structures with the proper widths. Some widths are still hardcoded because many FADTs have incorrect register lengths.
