2008-02-07[POWERPC] Use generic compat_sys_ptraceRoland McGrath
This replaces powerpc's compat_sys_ptrace with a compat_arch_ptrace and enables the new generic definition of compat_sys_ptrace instead. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-07[POWERPC] Use generic compat_ptrace_requestRoland McGrath

2008-02-07[POWERPC] Use regset code for PTRACE_*REGS* requestsRoland McGrath
This replaces all the code for powerpc PTRACE_*REGS* requests with simple calls to copy_regset_from_user and copy_regset_to_user. All the ptrace formats are either the whole corresponding user_regset format (core dump format) or a leading subset of it, so we can get rid of all the remaining embedded knowledge of both those layouts and of the internal data structures they correspond to. Only the user_regset accessors need to implement that. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-07[POWERPC] Switch to generic compat_binfmt_elf codeRoland McGrath
This switches the CONFIG_PPC64 support for 32-bit ELF to use the generic fs/compat_binfmt_elf.c implementation instead of our own binfmt_elf32.c. Since so much is the same between 32/64, there is only one macro we have to define to make the generic support work out of the box.

2008-02-07[POWERPC] Switch to using user_regset-based core dumpsRoland McGrath
This switches powerpc to using the user_regset-based code for ELF core dumps. The core dumps come out exactly the same either way, except that the NT_PPC_VMX note is now omitted for any thread that never touched its Altivec registers (thread_struct.vr_used).

2008-02-07[POWERPC] Add user_regset compat supportRoland McGrath
This extends task_user_regset_view CONFIG_PPC64 with support for the 32-bit view of register state, compatible with what a CONFIG_PPC32 kernel provides. This will enable generic machine-independent code to access user-mode threads' registers for debugging and dumping.

2008-02-07[POWERPC] Add user_regset_view definitionsRoland McGrath
This provides the task_user_regset_view entry point and support for all the native-mode (64 on CONFIG_PPC64, 32 on CONFIG_PPC32) thread register state. This will enable generic machine-independent code to access user-mode threads' registers for debugging and dumping.

2008-02-07[POWERPC] Use user_regset accessors for GPRsRoland McGrath
This implements user_regset-style accessors for the powerpc general registers. In the future these functions will be the only place that needs to understand the user_regset layout (core dump format) and how it maps to the internal representation of user thread state.

2008-02-07[POWERPC] ptrace accessors for special regs MSR and TRAPRoland McGrath
This isolates the ptrace code for the special-case registers msr and trap from the ptrace-layout dispatch code. This should inline away completely. It cleanly separates the low-level machine magic that has to be done for deep reasons, from the superficial details of the ptrace interface.

2008-02-06[POWERPC] 4xx: PCIe indirect DCR spinlock fix.Valentine Barshak
Since we have mfdcri() and mtdcri() as macros, we can't use constructions, such as "mtdcri(base, reg, mfdcri(base, reg) | val)". In this case the mfdcri() stuff is not evaluated first. It's evaluated inside the mtdcri() macro and we have the dcr_ind_lock spinlock acquired twice. To avoid this error, I've added __mfdcri()/__mtdcri() inline functions that take the lock after register name fix-up.

2008-02-07[POWERPC] Update default irq servers when boot cpu is removedNathan Fontenot
The xics code does update the default server information when the boot cpu is removed. This patch recognizes when the boot cpu is being removed and updates the appropriate information based on the new 'boot cpu'. Failure to update this information can causes us to leave irqs pinned to cpus that are being removed, especially when removing the boot cpu. The cpu is removed from the kernel, but cpu dlpar remove operations fail since we cannot return the cpu to the hypervisor.

2008-02-07[POWERPC] Split xics_teardown_cpu()Nathan Fontenot
This splits off the kexec path bits of the xics_teardown_cpu() routine into its own xics_kexec_teardown_cpu() routine. With the previous combined routine the CPPR for a cpu that is being removed may have its CPPR reset in the plpar_eoi() call (which explicitly sets the CPPR to a non-zero value). Splitting of the kexec bits of the code prevents this from happening in the cpu remove path. Once again, this does not cause the cpu remove from the kernel to fail, but it does cause cpu dlpar operations to not be able to return the cpu to the hypervisor.

2008-02-07[POWERPC] Update irq descriptor affinityNathan Fontenot
The affinity mask in the virq descriptor needs to be set before we reset the affinity for the virq. Without doing this the call to get the new irq server fails and we end up leaving the virq pinned to the cpu we are removing. This does not fail the cpu remove from the kernel, but it does prevent cpu dlpar remove operations from returning the cpu to the hypervisor.

2008-02-07[POWERPC] bootwrapper: Build multiple cuImagesGrant Likely
Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.

2008-02-07[POWERPC] Fake NUMA emulation for PowerPCBalbir Singh
Here's a dumb simple implementation of fake NUMA nodes for PowerPC. Fake NUMA nodes can be specified using the following command line option numa=fake=<node range> node range is of the format <range1>,<range2>,...<rangeN> Each of the rangeX parameters is passed using memparse(). I find the patch useful for fake NUMA emulation on my simple PowerPC machine. I've tested it on a numa box with the following arguments numa=fake=512M numa=fake=512M,768M numa=fake=256M,512M mem=512M numa=fake=1G mem=768M numa=fake= without any numa= argument The other side-effect introduced by this patch is that; in the case where we don't have NUMA information, we now set a node online after adding each LMB. This node could very well be node 0, but in the case that we enable fake NUMA nodes, when we cross node boundaries, we need to set the new node online.

2008-02-06[POWERPC] Xilinx: hwicap driverStephen Neuendorffer
This includes code for new fifo-based xps_hwicap in addition to the older opb_hwicap, which has a significantly different interface. The common code between the two drivers is largely shared. Significant differences exists between this driver and what is supported in the EDK drivers. In particular, most of the architecture-specific code for reconfiguring individual FPGA resources has been removed. This functionality is likely better provided in a user-space support library. In addition, read and write access is supported. In addition, although the xps_hwicap cores support interrupt-driver mode, this driver only supports polled operation, in order to make the code simpler, and since the interrupt processing overhead is likely to slow down the throughput under Linux.

2008-02-06[POWERPC] arch/powerpc/sysdev: Add missing of_node_putJulia Lawall
The functions of_find_compatible_node and of_find_node_by_type both call of_node_get on their result. So any error handling code thereafter should call of_node_put(np). This is taken care of in the case where there is a goto out, but not when there is a direct return. The function irq_alloc_host puts np into the returned structure, which is stored in the global variable mpc8xx_pic_host, so the reference count should be set for the lifetime of that variable. The current solution ups the reference count again in the argument to irq_alloc_host so that it can be decremented on the way out. This seems a bit unnecessary, and also doesn't work in the case where irq_alloc_host fails, because then the reference count only goes does by one, whereas it should go down by two. A better solution is to not increment the reference count in the argument to irq_alloc_host and only decrement it on the way out in an error case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * E = \(of_get_parent\|of_find_compatible_node\)(...); if (E == NULL) S ... when != of_node_put(...,(T1)E,...) when != if (E != NULL) { ... of_node_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != of_node_put(...,(T2)E,...) when != if (E != NULL) { ... of_node_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Kumar Gala <galak@gate.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
