We ignore all the generated files called "vmlinux*" from the top-level gitignore, but that also ends up catching a few files that we track, and that people do edit. Notably the "vmlinux.lds.S" file, that each architecture has. You can always use "git add -f" to override the ignore file, but we might as well just make it explicit for this file.

The VBI DMA is handled in a special way and is marked with a bit. However, that bit was set at the wrong time and could be cleared by mistake if a PCM (or other) DMA request would arrive before the VBI DMA was completed. So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine. Signed-off-by:

This basically reverts commit 4e44f349, while waiting for it to be re-done more completely. There are cases of people mixing "time()" with higher-resolution time sources, and we need to take the nanosecond offsets into account. Ingo has a patch that does that, but it's still under some discussion. In the meantime, just revert back to the old simple situation of just doing the whole exact timesource calculations. But rather than using do_gettimeofday(), use the internal nanosecond resolution getnstimeofday(), which at least avoids one unnecessary conversion (since we really don't care about whether the fractional seconds are nanoseconds or microseconds - we'll just throw them away).

This sorts out the various lists and related locks in the spu code. In detail: - the per-node free_spus and active_list are gone. Instead struct spu gained an alloc_state member telling whether the spu is free or not - the per-node spus array is now locked by a per-node mutex, which takes over from the global spu_lock and the per-node active_mutex - the spu_alloc* and spu_free function are gone as the state change is now done inline in the spufs code. This allows some more sharing of code for the affinity vs normal case and more efficient locking - some little refactoring in the affinity code for this locking scheme Signed-off-by:

From: Maynard Johnson <mpjohn@us.ibm.com> This patch updates the existing arch/powerpc/oprofile/op_model_cell.c to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code. Exports spu_set_profile_private_kref and spu_get_profile_private_kref which are used by OProfile to store private profile information in spufs data structures. Also incorporated several fixes from other patches (rrn). Check pointer returned from kzalloc. Eliminated unnecessary cast. Better error handling and cleanup in the related area. 64-bit unsigned long parameter was being demoted to 32-bit unsigned int and eventually promoted back to unsigned long. Signed-off-by:

Exports spu_switch_event_register and spu_switch_event_unregister so that OProfile can get access to the notifications provided. Signed-off-by:

This patch links spus according to their physical position using information provided by the firmware through a special vicinity device-tree property. This property is present in current version of Malta firmware. Example of vicinity properties for a node in Malta: Node: Vicinity property contains phandles of: spe@0 [ spe@100000 , mic-tm@50a000 ] spe@100000 [ spe@0 , spe@200000 ] spe@200000 [ spe@100000 , spe@300000 ] spe@300000 [ spe@200000 , bif0@512000 ] spe@80000 [ spe@180000 , mic-tm@50a000 ] spe@180000 [ spe@80000 , spe@280000 ] spe@280000 [ spe@180000 , spe@380000 ] spe@380000 [ spe@280000 , bif0@512000 ] Only spe@* have a vicinity property (e.g., bif0@512000 and mic-tm@50a000 do not have it).

This patch makes the scheduller honor affinity information for each context being scheduled. If the context has no affinity information, behaviour is unchanged. If there are affinity information, context is schedulled to be run on the exact spu recommended by the affinity placement algorithm. Signed-off-by:

Arnd Bergmann authored
This patch provides the spu affinity placement logic for the spufs scheduler. Each time a gang is going to be scheduled, the placement of a reference context is defined. The placement of all other contexts with affinity from the gang is defined based on this reference context location and on a precomputed displacement offset. Signed-off-by:

This patch adds support for additional flags at spu_create, which relate to the establishment of affinity between contexts and contexts to memory. A fourth, optional, parameter is supported. This parameter represent a affinity neighbor of the context being created, and is used when defining SPU-SPU affinity. Affinity is represented as a doubly linked list of spu_contexts. Signed-off-by:

This patch allows the use of spu affinity on QS20, whose original FW does not provide affinity information. This is done through two hardcoded arrays, and by reading the reg property from each spu. Signed-off-by:

This patch adds affinity data to each spu instance. A doubly linked list is created, meant to connect the spus in the physical order they are placed in the BE. SPUs near to memory should be marked as having memory affinity. Adjustments of the fields acording to FW properties is done in separate patches, one for CPBW, one for Malta (patch for Malta under testing). Signed-off-by:

Addition of a spufs-global "cbe_info" array. Each entry contains information about one Cell/B.E. node, namelly: * list of spus (both free and busy spus are in this list); * list of free spus (replacing the static spu_list from spu_base.c) * number of spus; * number of reserved (non scheduleable) spus. SPE affinity implementation actually requires only access to one spu per BE node (since it implements its own pointer to walk through the other spus of the ring) and the number of scheduleable spus (n_spus - non_sched_spus) However having this more general structure can be useful for other functionalities, concentrating per-cbe statistics / data.
