* | x86: support for new UV apicJack Steiner2008-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UV supports really big systems. So big, in fact, that the APICID register does not contain enough bits to contain an APICID that is unique across all cpus. The UV BIOS supports 3 APICID modes: - legacy mode. This mode uses the old APIC mode where APICID is in bits [31:24] of the APICID register. - x2apic mode. This mode is whitebox-compatible. APICIDs are unique across all cpus. Standard x2apic APIC operations (Intel-defined) can be used for IPIs. The node identifier fits within the Intel-defined portion of the APICID register. - x2apic-uv mode. In this mode, the APICIDs on each node have unique IDs, but IDs on different node are not unique. For example, if each mode has 32 cpus, the APICIDs on each node might be 0 - 31. Every node has the same set of IDs. The UV hub is used to route IPIs/interrupts to the correct node. Traditional APIC operations WILL NOT WORK. In x2apic-uv mode, the ACPI tables all contain a full unique ID (note: exact bit layout still changing but the following is close): nnnnnnnnnnlc0cch n = unique node number l = socket number on board c = core h = hyperthread Only the "lc0cch" bits are written to the APICID register. The remaining bits are supplied by having the get_apic_id() function "OR" the extra bits into the value read from the APICID register. (Hmmm.. why not keep the ENTIRE APICID register in per-cpu data....) The x2apic-uv mode is recognized by the MADT table containing: oem_id = "SGI" oem_table_id = "UV-X" Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | x86: fix build breakage when PCI is define and PARAVIRT is notRavikiran G Thirumalai2008-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Fix the the build breakage when PARAVIRT is defined but PCI is not This fixes problem reported at: http://marc.info/?l=linux-kernel&m=120525966600698&w=2 - Make is_vsmp_box() available even when PARAVIRT is not defined. This is needed to determine if tsc's are reliable as a time source even when PARAVIRT is not defined. - split vsmp_init to use is_vsmp_box() and set_vsmp_pv_ops() set_vsmp_pv_ops will do nothing if PCI is not enabled in the config.

| | | | | | | | | | | | | | | | | | | | | | Remove the last leftovers from the files. Move the ones that are still used to the files they belong, the others that grep can't reach, simply throw away.

* | x86: use specialized routine for setup per-cpu areaGlauber de Oliveira Costa2008-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | We use the same routing as x86_64, moved now to setup.c. Just with a few ifdefs inside. Note that this routing uses prefill_possible_map(). It has the very nice side effect of allowing hotplugging of cpus that are marked as present but disabled by acpi bios.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates smpcommon.c with functions that are equal between architectures. The i386-only init_gdt is ifdef'd. Note that smpcommon.o figures twice in the Makefile: this is because sub-architectures like voyager that does not use the normal smp_$(BITS) files also have to access them Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | The module scx200 were renamed to scx200_32 by the merge of the 32 and 64 bit x86 arch trees.

* x86: restore correct module name for apmSam Ravnborg2008-02-041-1/+2
| | | | | | | | | | | | | | | | The apm module were renamed to apm_32 during the merge of 32 and 64 bit x86 which is unfortunate. As apm is 32 bit specific we like to keep the _32 in the filename but the module should be named apm. Fix this in the Makefile.

| | | | | | | | | | | | | | | | | | reboot_{32|64}.c unification patch. This patch unifies the code from the reboot_32.c and reboot_64.c files. It has been tested in computers with X86_32 and X86_64 kernels and it looks like all reboot modes work fine (EFI restart system hasn't been tested yet). Probably I made some mistakes (like I usually do) so I hope we can identify and fix them soon.

| | | | | | | | | | | | | | | | | | Combine the 32 and 64 bit specific Makefiles in one file. While doing so link order was (almost) preserved on 32 bit but on 64 bit link order changed a lot. Patch was checked with defconfig + allyesconfig builds. The same .o files were linked in these configurations. To keep readability of the Makefiles a few Kconfig symbols was added/modified and it was checked that they were not used anywhere else. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: "H.
