This adds support for the PCI bus on Celleb with new "I/O routines for PowerPC." External PCI on Celleb must do explicit synchronization with devices (Bus has no automatic synchronization feature). Signed-off-by:

This supports Power/Reset buttons on Beat on Celleb. On Beat, we have an event from Beat if Power button or Reset button is pressed. This patch catches the event and convert it to a signal to INIT process by calling ctrl_alt_del() function. /sbin/inittab have no entry to turn the machine power off so we have to detect if power button is pressed or not internally in our driver. This idea is taken from PS3's event handling subsystem. Signed-off-by:

Now that dcr_host_t contains the base address, we can use that in the axon_msi code, rather than storing it separately. Signed-off-by:

Michael Ellerman authored
In its current form, dcr_map() doesn't remember the base address you passed it, which means you need to store it somewhere else. Rather than adding the base to another struct it seems simpler to store it in the dcr_host_t. Signed-off-by:

The trick for finding the right defconfig is neat, but you forgot to provide an i686_defconfig. ;-) More seriously, cross compiling the defconfig is often useful, e.g. for testing the compilation of patches that touch multiple architectures, and this patch therefore chooses g5_defconfig if $(CROSS_COMPILE) is non-empty.

This keeps an unstripped copy of the vDSO images built before they are stripped and embedded in the kernel. The unstripped copies get installed in $(MODLIB)/vdso/ by "make install". These files can be useful when they contain source-level debugging information. Signed-off-by:

Add CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing get_paca() preemption. Cheat a little, just use debug_smp_processor_id() in the debug version of get_paca(): it contains all the right checks and reporting, though get_paca() doesn't really use smp_processor_id(). Use local_paca for what might have been called __raw_get_paca(). Silence harmless warnings from io.h and lparcfg.c with local_paca - it is okay for iseries_lparcfg_data to be referencing shared_proc with preemption enabled: all cpus should show the same value for shared_proc. Why do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT? I don't know, ppc64 appears to get along fine without it. Signed-off-by:

On non-book-E, exceptions execute in real mode. If a fault happens that leads to a register dump, the kernel currently prints XXXXXXXX because it doesn't realize that PC is a physical address. This patch checks whether instruction address translation is turned on, and if not converts PC into a virtual address. Signed-off-by:

The /proc/bus/pci/* files list PCI domain numbers only for devices that claim to be on a multi-domain system. The check for this is broken on powerpc, because the buid value is truncated to 32 bits. There is at least one machine (IBM QS21) that only uses the high-order bits of the buid, so the return value of pci_proc_domain() ends up being always zero, which makes /proc/bus/pci useless. Change the logic to always return '1' for a nonzero buid value. Signed-off-by:

This restores the CHECK_FULL_REGS sanity check to every place that can access the nonvolatile GPRs for ptrace. This is already done for native-bitwidth PTRACE_PEEKUSR, but was omitted for many other cases (32-bit ptrace, PTRACE_GETREGS, etc.); I think there may have been more uniform checks before that were lost in the recent cleanup of GETREGS et al.

The entries are only 32-bit, so restrict the virtual address to stay below 0xffff_ffff. With KERNELBASE set to 0xc000_0000, this in effect restricts access to the first 1GB of real memory. Make setup_kcore conditional on CONFIG_PROC_KCORE for both 32/64. Signed-off-by:

Move out the old-style exception parsers to a separate function, and don't call it on platforms that have a platform-specific handler. It would make sense to move out the generic versions into their platforms instead, but that can be done gradually down the road. Signed-off-by:

In the MPIC U3 MSI code, we call u3msi_compose_msi_msg() once for each MSI. This is overkill, as the address is per pci device, not per MSI. So setup the address once, and just set the data per MSI. Signed-off-by:

Currently rtas_change_msi() returns either the error code from RTAS, or if the RTAS call succeeded the number of irqs that were configured by RTAS. This makes checking the return value more complicated than it needs to be. Instead, have rtas_change_msi() check that the number of irqs configured by RTAS is equal to what we requested - and return an error otherwise. This makes the return semantics match the usual 0 for success, something else for error. Signed-off-by:
