* [PATCH] x86_64: Support more than 8 cores on AMD systemsAndi Kleen2005-07-29
| | | | | | | | | Use physical mode instead of logical mode to address more CPUs. This is also used in the CPU hotplug case to avoid a race. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64 genapic updateJason Davis2005-04-16
| | | | | | | | | | | | | | | | | | x86_64 genapic mechanism should be aware of machines that use physical APIC mode regardless of how many clusters/processors are detected. ACPI 3.0 FADT makes this determination very simple by providing a feature flag "force_apic_physical_destination_mode" to state whether the machine unconditionally uses physical APIC mode. Unisys' next generation x86_64 ES7000 will need to utilize this FADT feature flag in order to boot the x86_64 kernel in the correct APIC mode. This patch has been tested on both x86_64 commodity and ES7000 boxes.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
