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:

Glauber Costa authored
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:

Report when microcode was successfully updated. It used to be there but now with DEBUG unset it becomes very silent. Also some cosmetic fixes. Signed-off-by:
