* [PATCH] x86-64: Make remote TLB flush more scalableAndi Kleen2005-09-12
| | | | | | | | | | | | | | | | | | | | | | | 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 Also some minor cleanup in the smp flush code and remove some outdated debug code.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.

* [PATCH] x86-64: Support dualcore and 8 socket systems in k8 fallback node ↵Andi Kleen2005-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

| * ppc64: Set up PCI tree from Open Firmware device treePaul Mackerras2005-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds code which gives us the option on ppc64 of instantiating the PCI tree (the tree of pci_bus and pci_dev structs) from the Open Firmware device tree rather than by probing PCI configuration space. The OF device tree has a node for each PCI device and bridge in the system, with properties that tell us what addresses the firmware has configured for them and other details. There are a couple of reasons why this is needed. First, on systems with a hypervisor, there is a PCI-PCI bridge per slot under the PCI host bridges. These PCI-PCI bridges have special isolation features for virtualization. We can't write to their config space, and we are not supposed to be reading their config space either. The firmware tells us about the address ranges that they pass in the OF device tree. Secondly, on powermacs, the interrupt controller is in a PCI device that may be behind a PCI-PCI bridge. If we happened to take an interrupt just at the point when the device or a bridge on the path to it was disabled for probing, we would crash when we try to access the interrupt controller. I have implemented a platform-specific function which is called for each PCI bridge (host or PCI-PCI) to say whether the code should look in the device tree or use normal PCI probing for the devices under that bridge. On pSeries machines we use the device tree if we're running under a hypervisor, otherwise we use normal probing. On powermacs we use normal probing for the AGP bridge, since the device for the AGP bridge itself isn't shown in the device tree (at least on my G5), and the device tree for everything else. This has been tested on a dual G5 powermac, a partition on a POWER5 machine (running under the hypervisor), and a legacy iSeries partition. Signed-off-by: Paul Mackerras <paulus@samba.org>

I've also moved there the stabs debug section, used the new macro in i386 linker script and added DWARF debug section to that. In the truth, I've not been able to verify the difference in GDB behaviour after this change (I've seen large improvements with another patch).
