A few xics cleanups: - Make some things static. - Be more consistent with error printing - interrupts are unsigned, error values are signed. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

Add hardware data breakpoint support. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

- 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>

- Remove the PPC_REG* defines - Wrap some more stuff with ifdef __KERNEL__ - Add missing PT_TRAP, PT_DAR, PT_DSISR defines - Add PTRACE_GETEVRREGS/PTRACE_SETEVRREGS, even though we dont use it on ppc64 we dont want to allocate them for something else.

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>

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>

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>

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>

When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. 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.

This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used the same PCI ROM mapping code). Without this, I get NULL MAC addresses for all 4 ports (it's a SUN QFE). With it, I get the correct addresses (the ones printed on the label on the card). Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This same patch was reported to fix the MAC address detection on sunhme (next patch). Most people seem to be running this on Sparcs or PPC machines, where we get the MAC address from their respective firmware rather than from the (previously broken) ROM mapping routines.

The PTE returned from handle_mm_fault is already marked as dirty and accessed if needed. Also, since this is not set with set_pte() (which sets NEWPAGE and NEWPROT as needed), this wouldn't work anyway. This version has been updated and fixed, thanks to some feedback from Jeff Dike.

The UML fault handler was recently changed to enforce PROT_NONE protections, by requiring VM_READ or VM_EXEC on VMA's. However, by mistake, things were changed such that VM_READ is always checked, also on write faults; so a VMA mapped with only PROT_WRITE is not readable (unless it's prefaulted with MAP_POPULATE or with a write), which is different from i386. Discovered while testing remap_file_pages protection support. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
