2008-04-17x86: support for new UV apicJack Steiner
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>

2008-04-17x86: define the macros and tables for blade functionsJack Steiner
Add UV macros for converting between cpu numbers, blade numbers and node numbers. Note that these are used ONLY within x86_64 UV modules, and are not for general kernel use. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: parsing for ACPI "SAPIC" tableJack Steiner
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.

2008-04-17x86: increase size of APICIDJack Steiner
Increase the number of bits in an apicid from 8 to 32. By default, MP_processor_info() gets the APICID from the mpc_config_processor structure. However, this structure limits the size of APICID to 8 bits. This patch allows the caller of MP_processor_info() to optionally pass a larger APICID that will be used instead of the one in the mpc_config_processor struct.

2008-04-17x86: add functions to determine if platform is a UV platformJack Steiner
Add functions that can be used to determine if an x86_64 system is a SGI "UV" system. UV systems come in 3 types and are identified by the OEM ID in the MADT. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change GET_APIC_ID() from an inline function to an out-of-line functionJack Steiner
Introduce a function to read the local APIC_ID. This change is in preparation for additional changes to the APICID functions that will come in a later patch. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: cleanup - rename VM_MASK to X86_VM_MASKgorcunov@gmail.com
This patch renames VM_MASK to X86_VM_MASK (which in turn defined as alias to X86_EFLAGS_VM) to better distinguish from virtual memory flags. We can't just use X86_EFLAGS_VM instead because it is also used for conditional compilation Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: paravirt_ops: don't steal memory resources in paravirt_disable_iospaceJeremy Fitzhardinge
The memory resource is also used for main memory, and we need it to allocate physical addresses for memory hotplug. Knobbling io space is enough to get the job done anyway.

2008-04-17x86: sparsemem: reduce i386 PAE section sizeJeremy Fitzhardinge
A 1G section size makes memory hotplug too coarse in a virtual environment. Retuce it by a factor of 2 to 512M. I would have liked to make it smaller, but it runs out of reserved flags in the page flags.

2008-04-17x86: merge smp_32.h and smp_64.h into smp.hGlauber Costa
Merge what's left from smp_32.h and smp_64.h into smp.h By now, they're basically extern definitions. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change naming of cpu_initialized_mask for xenGlauber Costa
xen does not use the global cpu_initialized mask, but rather, a specific one. So we change its name so it won't conflict with the upcoming movement of cpu_initialized_mask from smp_64.h to smp_32.h.

2008-04-17x86: merge SMP definitions of smp.hGlauber Costa
we merge everything that is inside CONFIG_SMP to smp.h. They differ a little bit, so we use CONFIG_X86_32_SMP and CONFIG_X86_64_SMP as markers. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: split safe_smp_processor_idGlauber Costa
This implementation in x86_64 is clean and consistent, but we sacrifice it for the sake of being equal to i386 (since the other way around would be harder). Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: merge includes in smp.hGlauber Costa

2008-04-17x86: surround apic headers in apic definitionsGlauber Costa
Although those constants are always defined in x86_64, and will have the effect of just including the headers in the very way we did before, I'm doing this in a separate patch to be conservative and avoid surprises.

2008-04-17x86: merge hard/logical_smp_processor_idGlauber Costa
The code is now the same between i386 and x86_64. We already know what happens when it reaches this point: They go away from the arch-specific headers, and suddenly appears in the common header. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: provide bogus hard_smp_processor_idGlauber Costa
We provide a bogus macro for x86_64 in case CONFIG_X86_LOCAL_APIC is not set. It will always be set for x86_64, so the effect is just to make the code equal to i386. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: surround hard_smp_processor_id in APIC_DEFINITIONGlauber Costa
APIC_DEFINITION is not defined in x86_64, so in practice, we keep our old code here. But as a nice side effect, the code is now equal to smp_32.h. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
