2005-11-14[PATCH] x86_64: Increase the maximum number of local APICs to the maximumAndi Kleen
This is needed for large multinode IBM systems which have a sparse APIC space in clustered mode, fully covering the available 8 bits. The previous kernels would limit the local APIC number to 127, which caused it to reject some of the CPUs at boot. I increased the maximum and shrunk the apic_version array a bit to make up for that (the version is only 8 bit, so don't need an full int to store) Cc: Chris McDermott <lcm@us.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-14[PATCH] i386/x86-64: Share interrupt vectors when there is a large number of ↵James Cleverdon
interrupt sources Here's a patch that builds on Natalie Protasevich's IRQ compression patch and tries to work for MPS boots as well as ACPI. It is meant for a 4-node IBM x460 NUMA box, which was dying because it had interrupt pins with GSI numbers > NR_IRQS and thus overflowed irq_desc. The problem is that this system has 270 GSIs (which are 1:1 mapped with I/O APIC RTEs) and an 8-node box would have 540. This is much bigger than NR_IRQS (224 for both i386 and x86_64). Also, there aren't enough vectors to go around. There are about 190 usable vectors, not counting the reserved ones and the unused vectors at 0x20 to 0x2F. So, my patch attempts to compress the GSI range and share vectors by sharing IRQs.

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!
