* [PATCH] ppc64: Add ptrace data breakpoint supportAnton Blanchard2005-09-12

* [PATCH] ppc64: Add definitions for new PTRACE callsAnton Blanchard2005-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | - 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. Again this might be better placed in include/asm-generic/siginfo.h Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] ppc64: Add PTRACE_{GET|SET}VRREGSRobert Jennings2005-09-12
| | | | | | | | | | | | | | | | | | The ptrace get and set methods for VMX/Altivec registers present in the ppc tree were missing for ppc64. This patch adds the 32-bit and 64-bit methods. Updated with the suggestions from Anton following the lines of his code snippet. Added: - flush_altivec_to_thread calls as suggested by Anton - piecewise copy of structure to preserve 32-bit vrsave data as per Anton (I consolidated the 32 and 64bit versions with 2 helper macros - Anton) Signed-off-by: Robert C Jennings <rcjenn@austin.ibm.com> Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* 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>

| | * | [IA64] Fix nasty VMLPT problem...Peter Chubb2005-08-31

The problem is that the number of bits for the virtual linear array short-format VHPT (Virtually mapped linear page table, VMLPT for short) is being tested incorrectly. There are two problems: 1. The PAL call that should tell the kernel the size of the virtual address space isn't implemented for the simulator, so the kernel uses the default 50. This is addressed separately in dc90e95f310f4f821c905b2aec8e9449bb3270fa 2. In arch/ia64/mm/init.c there's code to calcualte the size of the VMLPT based on the number of implemented virtual address bits and the page size. It checks to see if the VMLPT base address overlaps the top of the mapped region, but this check doesn't allow for the address space hole, and in fact will never trigger. Here's an alternative test and panic, that I think is more accurate. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * | [PATCH] MCA/INIT: use per cpu stacksKeith Owens2005-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of the change. Use per cpu MCA/INIT stacks. Change the SAL to OS state (sos) to be per process. Do all the assembler work on the MCA/INIT stacks, leaving the original stack alone. Pass per cpu state data to the C handlers for MCA and INIT, which also means changing the mca_drv interfaces slightly. Lots of verification on whether the original stack is usable before converting it to a sleeping process. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * | [IA64] MCA/INIT: avoid reading INIT record during INIT eventKeith Owens2005-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading the INIT record from SAL during the INIT event has proved to be unreliable, and a source of hangs during INIT processing. The new MCA/INIT handlers remove the need to get the INIT record from SAL. Change salinfo.c so mca.c can just flag that a new record is available, without having to read the record during INIT processing. This patch can be applied without the new MCA/INIT handlers. Also clean up some usage of NR_CPUS which should have been using cpu_online(). Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

| * | [PATCH] IB: fix CM use-after-freeRoland Dreier2005-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the CM REQ handling function gets to error2, then it frees cm_id_priv->timewait_info. But the next line goes through ib_destroy_cm_id() -> ib_send_cm_rej() -> cm_reset_to_idle(), which ends up calling cm_cleanup_timewait(), which dereferences the pointer we just freed.

We do this by sweeping the event lists before returning from a destroy calls, and then return the number of events already reported before the destroy call. This allows userspace wait until it has processed all events for an object returned from the kernel before it frees its context for the object. The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to change to return the event count, so bump the ABI version from 1 to 2. The userspace libibverbs library has already been updated to handle both the old and new ABI versions. Signed-off-by: Roland Dreier <rolandd@cisco.com>
