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:

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:

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. Signed-off-by:

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. Signed-off-by:

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:

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:

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:

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. Signed-off-by:

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. Signed-off-by:

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:

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. Signed-off-by:

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:

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:

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. Signed-off-by:

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:

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:

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:
