powerpc: Build kernel with -mcmodel=medium Finally remove the two level TOC and build with -mcmodel=medium. Unfortunately we can't build modules with -mcmodel=medium due to the tricks the kernel module loader plays with percpu data: # -mcmodel=medium breaks modules because it uses 32bit offsets from # the TOC pointer to create pointers where possible. Pointers into the # percpu data area are created by this method. # # The kernel module loader relocates the percpu data section from the # original location (starting with 0xd...) to somewhere in the base # kernel percpu data space (starting with 0xc...). We need a full # 64bit relocation for this to work, hence -mcmodel=large. On older kernels we fall back to the two level TOC (-mminimal-toc) Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

[POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseries Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc/pseries: Make request_ras_irqs() available to other pseries code At the moment only the RAS code uses event-sources interrupts (for EPOW events and internal errors) so request_ras_irqs() (which actually requests the event-sources interrupts) is found in ras.c and is static. We want to be able to use event-sources interrupts in other pseries code, so let's rename request_ras_irqs() to request_event_sources_irqs() and move it to event_sources.c. This will be used in an upcoming patch that adds support for IO Event interrupts that come through as event sources.

powerpc: Change places using CONFIG_KEXEC to use CONFIG_KEXEC_CORE instead. Commit 2965faa5e03d ("kexec: split kexec_load syscall from kexec core code") introduced CONFIG_KEXEC_CORE so that CONFIG_KEXEC means whether the kexec_load system call should be compiled-in and CONFIG_KEXEC_FILE means whether the kexec_file_load system call should be compiled-in. These options can be set independently from each other. Since until now powerpc only supported kexec_load, CONFIG_KEXEC and CONFIG_KEXEC_CORE were synonyms. That is not the case anymore, so we need to make a distinction. Almost all places where CONFIG_KEXEC was being used should be using CONFIG_KEXEC_CORE instead, since kexec_file_load also needs that code compiled in.

powerpc: Add support for new hcall H_BEST_ENERGY Create sysfs interface to export data from H_BEST_ENERGY hcall that can be used by administrative tools on supported pseries platforms for energy management optimizations. sys/device/system/cpu/pseries_(de)activate_hint_list and sys/device/system/cpu/cpuN/pseries_(de)activate_hint will provide hints for activation and deactivation of cpus respectively. These hints are abstract number given by the hypervisor based on the extended knowledge the hypervisor has regarding the system topology and resource mappings. The activate and the deactivate sysfs entry is for the two distinct operations that we could do for energy savings. When we have more capacity than required, we could deactivate few core to save energy. The choice of the core to deactivate will be based on /sys/devices/system/cpu/deactivate_hint_list. The comma separated list of cpus (cores) will be the preferred choice. If we have to activate some of the deactivated cores, then /sys/devices/system/cpu/activate_hint_list will be used. The per-cpu file /sys/device/system/cpu/cpuN/pseries_(de)activate_hint further provide more fine grain information by exporting the value of the hint itself.

[POWERPC] Hotplug memory remove notifications for powerpc Hotplug memory remove notifier for 64-bit powerpc. This gets invoked by writing to /proc/ppc64/ofdt the string "remove_node " followed by the firmware device tree pathname of the node that needs to be removed. In response, this adjusts the sections and removes sysfs entries by calling __remove_pages(). Then it calls arch-specific code to get rid of the hardware MMU mappings for the section of memory.

powerpc/pseries: Add support for IO event interrupts This patch adds support for handling IO Event interrupts which come through at the /event-sources/ibm,io-events device tree node. The interrupts come through ibm,io-events device tree node are generated by the firmware to report IO events. The firmware uses the same interrupt to report multiple types of events for multiple devices. Each device may have its own event handler. This patch implements a plateform interrupt handler that is triggered by the IO event interrupts come through ibm,io-events device tree node, pull in the IO events from RTAS and call device event handlers registered in the notifier list. Device event handlers are expected to use atomic_notifier_chain_register() and atomic_notifier_chain_unregister() to register/unregister their event handler in pseries_ioei_notifier_list list with IO event interrupt. Device event handlers are responsible to identify if the event belongs to the device event handler. The device event handle should return NOTIFY_OK after the event is handled if the event belongs to the device event handler, or NOTIFY_DONE otherwise.
