2005-09-12[PATCH] x86-64: Some cleanup and optimization to the processor data area.Andi Kleen6-14/+18
- Remove unused irqrsp field - Remove pda->me - Optimize set_softirq_pending slightly Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Make remote TLB flush more scalableAndi Kleen4-58/+117
Instead of using a global spinlock to protect the state of the remote TLB flush use a lock and state for each sending CPU. To tell the receiver where to look for the state use 8 different call vectors. Each CPU uses a specific vector to trigger flushes on other CPUs. Depending on the received vector the target CPUs look into the right per cpu variable for the flush data. When the system has more than 8 CPUs they are hashed to the 8 available vectors. The limited global vector space forces us to this right now. In future when interrupts are split into per CPU domains this could be fixed, at the cost of needing more IPIs in flat mode. Also some minor cleanup in the smp flush code and remove some outdated debug code. Requires patch to move cpu_possible_map setup earlier.

2005-09-12[PATCH] x86-64: Fix 32bit sendfileTsuneo.Yoshioka@f-secure.com3-3/+3
If we use 64bit kernel on ia64/x86_64/s390 architecture, and we run 32bit binary on 32bit compatibility mode, sendfile system call seems be not set offset argument. This is because sendfile's return value is not zero but the code regards the result by return value is zero or not. This problem will be affect to ia64/x86_64/s390 and not affect to other architecture does not affect other architecture (mips/parisc/ppc64/sparc64).

One machine is constantly throwing NMI watchdog timeouts in mce_log This was one attempt to fix it. (AK: this doesn't actually fix the bug I'm seeing unfortunately, probably drop.

2005-09-12[PATCH] x86-64: Reverse order of bootmem listsAndi Kleen1-3/+11
This leads to bootmem allocating first from node 0 instead of from the last node. This avoids swiotlb allocating on the last node, which doesn't really work on a machine with >4GB. Note: there is a better patch around from someone else that gets rid of the pgdat list completely. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Support dualcore and 8 socket systems in k8 fallback node ↵Andi Kleen4-25/+63
parsing In particular on systems where the local APIC space and node space is very different from the Linux CPU number space. Previously the older NUMA setup code directly parsing the K8 northbridge registers had some issues on 8 socket or dual core systems. This patch fixes them. This is mainly done by fixing some confusion between Linux CPU numbers and local APIC ids. We now pass the local APIC IDs to later code, which avoids mismatches. Also add some heuristics to detect cases where the Hypertransport nodeids and the local APIC IDs don't match, but are shifted by a constant offset. This is still all quite hackish, hopefully BIOS writers fill in correct SRATs instead. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Optimize the deadlock avoidance check on the global cpuset semaphore cpuset_sem.

- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is as follows: /* * Get or set a debug register. The first 16 are DABR registers and the * second 16 are IABR registers. */ #define PTRACE_GET_DEBUGREG 25 #define PTRACE_SET_DEBUGREG 26 DABR == data breakpoint and IABR = instruction breakpoint in IBM speak. We could split out the IABR into 2 more ptrace calls but I figured there was no need and 16 DABR registers should be more than enough (POWER4/POWER5 have one). - Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt find any standards on either of these so I copied what ia64 is doing.
