To allow userspace to automatically load modules, we need to hook up uevent for ps3_system_bus devices. I've used the form 'ps3:%d' with the ps3_match_id, since that's what we use for matching drivers. Signed-off-by:

Rework the PS3 system bus to unify device support. - DMA region sizes must be a power of two - storage bus DMA updates: - Small fixes for the PS3 DMA core: o fix alignment bug o kill superfluous test o indentation o spelling o export ps3_dma_region_{create,free}() - ps3_dma_region_init(): o Add `addr' and `len' parameters, so you can create a DMA region that does not cover all memory (use `NULL' and `0' to cover all memory). This is needed because there are not sufficient IOMMU resources to have all DMA regions cover all memory. o Uninline - Added remove and shutdown routines to all drivers. - Added loadable module support to all drivers. - Added HV calls for iopte management (needed by sound driver).

On Power machines supporting VRMA, Kexec/Kdump does not work. VRMA (virtual real-mode area) means that accesses with IR/DR = 0 (i.e. the MMU "off") actually still go through the hash table, using entries put there by the hypervisor. This means that when we clear out the hash table on kexec, we need to make sure these entries are left untouched. This also adds plpar_pte_read_raw() on the lines of plpar_pte_remove_raw().

In some of the PPC970 based systems, interrupt would be distributed to offline cpus also even when booted with "maxcpus=1". So check whether cpu online map and cpu present map are equal or not. If they are equal default_distrib_server is used as interrupt server otherwise boot cpu (default_server) used as interrupt server. In addition to this, if an interrupt is assigned to a specific cpu (ie smp affinity) and if that cpu is not online, the earlier code used to return the default_distrib_server as interrupt server. This introduces an additional parameter to the get_irq function, called strict_check. Based on this parameter, if the cpu is not online either default_distrib_server or -1 is returned. Signed-off-by:

On pSeries the firmware features are not setup until ppc_md.init_early, so we can't do the firmware feature sections fixups till after this. Currently firmware feature sections is only used on iSeries which inits the firmware features much earlier. This is a bug in waiting on pSeries. Signed-off-by:

For POWERPC, stolen time accounts for cycles lost to the hypervisor or PURR cycles attributed to the other SMT thread. Hence, when a PURR is available, we should still calculate stolen time, irrespective of being virtualised. Signed-off-by:

This patch adds irq_create_direct_mapping(). This routine is an alternative to irq_create_mapping(), for irq controllers that can use linux virq numbers directly as hardware numbers. Signed-off-by:

Michael Ellerman authored
A future patch will need the logic at the end of irq_create_mapping() which setups a virq and installs it in the irq_map. So split it out into a new function irq_setup_virq(). Signed-off-by:

Uninline virq_to_hw and export it so modules can use it. The alternative would be to export the irq_map array instead, but it's an infrequently called function, and keeping the array unexported seems considerably cleaner. Signed-off-by:

There are 2 config options that indicate whether the platform being built has a device tree source file associated with it. Namely, CONFIG_WANT_DEVICE_TREE and CONFIG_DEVICE_TREE. When CONFIG_WANT_DEVICE_TREE is 'y' and CONFIG_DEVICE_TREE isn't an empty string, automatically wrap the specified device tree with the zImage being built. To achieve this, the 'dts' variable will only be set when the conditions above are true. The changes to the zImage.initrd.% and zImage.% rules cause the device tree to be wrapped when 'dts' is set; otherwise, they will work as they previosly did (i.e., build a zImage with no device tree).

Mark A. Greer authored
Being able to selectively wrap a device tree with the zIimage at build time has been deemed unnecessary, so this removes Makefile support for that feature. Signed-off-by:

cpu_purr_data is a per-cpu array used to account for stolen time on partitioned systems. It used to be the case that cpus accessed each others' cpu_purr_data, so each entry was protected by a spinlock. However, the code was reworked ("Simplify stolen time calculation") with the result that each cpu accesses its own cpu_purr_data and not those of other cpus. This means we can get rid of the spinlock as long as we're careful to disable interrupts when accessing cpu_purr_data in process context. Signed-off-by:Nathan Lynch <ntl@pobox.com> Signed-off-by:

With both generic rtc and powerpc timer suspend / resume code now in the (powerpc.git) tree, powerpc platforms using the generic timer and enabling power management will have timer.o linked in the kernel, which they don't need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save zero-time and return no error on suspend... As a possible solution we can choose not to build timer.o when RTC_CLASS is enabled. However, I can imagine systems with 2 rtc's, one served by the ppc-rtc, another one generic built as a module, in which case using the ppc-rtc for suspend / resume will be impossible. Not to say, that such a configuration would be ugly... Signed-off-by:
