Add kernel support for new ACPI "sapic" tables that contain 16-bit APICIDs. This patch simply adds parsing of an optional SAPIC table if present. Otherwise, the traditional local APIC table is used. Note: the SAPIC table is not a new ACPI table - it exists on other architectures but is not currently recognized by x86_64.

ACPI tables follow a tree structure in memory. The root of the tree is the RSDP (Root System Description Pointer). To find the RSDP, the OS searches for the signature "RSD PTR " in well known physical memory locations. Then the OS computes a table checksum to verify that the signature is really part of a valid table header. Some systems have a proper signature but an invalid checksum; followed elsewhere by a proper signature with valid checksum. http://bugzilla.kernel.org/show_bug.cgi?id=9444 The Linux RSDP scanning code bailed out on those systems and as a result they booted with ACPI disabled. Fix this by deleting the Linux RSDP scanning code and plugging in the ACPICA RSDP scanning code. Signed-off-by: NLen Brown <len.brown@intel.com>

由 Mike Travis 提交于
This patch converts the x86_cpu_to_apicid array to be a per cpu variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. MP_processor_info() is one of the functions that require access to the x86_cpu_to_apicid array before the per_cpu data area is setup. For this case, a pointer to the __initdata array is initialized in setup_arch() and removed in smp_prepare_cpus() after the per_cpu data area is initialized. A second change is included to change the initial array value of ARCH i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.

Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

Insert HPET resources after pci probing has been completed in order to avoid resource conflicts with PCI resource reservation.

Matthias Lenk reports that the PCI subsystem would move the HPET on SB400/SB600-based systems, where the HPET is in BAR1 of the SMbus controller. The reason? The ACPI layer registered the PCI MMIO range as being busy too early, before PCI enumeration had happened, causing the PCI layer to decide that it should relocate the resources somewhere else. Firmware resources should be marked busy _after_ the PCI enumeration and probing has happened, not before. Remove the too-early reservation, we'll fix it up to do it properly later. In the meantime, this solves the regression.

I have a Dell Optiplex GX240 and when I boot Linux, ACPI gets set up by only acpi=ht. dmesg shows the following line: DELL GX240 detected: force use of acpi=ht Everything seemed to be fine. However, I discovered that everything is not fine. The USB controller works so slowly that copying a few (uncached) 1 megabyte large photos from a USB-enabled digital camera takes many minutes instead of a couple of seconds. I am using Linux 2.6.21.1 on a Debian 4.0 ("Etch") system. I thought that this might be related to ACPI. So I tried to boot with _only_ "acpi=force" appended to the kernel command line. Voila, the USB controller started to work at full speed and copying photos from my digital camera took only seconds. I tested the system with "acpi=force" and could not find anything which did not work. I thought that this might be related to interrupts and APIC as well. (Note that this is APIC, not ACPI.) I tried booting with _only_ "noapic" and "nolapic" appended to the command line. Again, the USB controller started to work at full speed.

Timer overrides are normally disabled on Nvidia board because they are commonly wrong, except on new ones with HPET support. Unfortunately there are quite some Asus boards around that don't have HPET, but need a timer override.
