2007-02-07[POWERPC] Celleb: consolidate spu management opsIshizaki Kou
Spu management ops in arch/platforms/cell/spu_priv1_mmio.h can be used commonly in of based platform. This patch separates spu management ops from native cell code and uses on celleb platform.

2006-12-04[POWERPC] cell: abstract spu management routinesGeoff Levand
This adds a platform specific spu management abstraction and the coresponding routines to support the IBM Cell Blade. It also removes the hypervisor only resources that were included in struct spu. Three new platform specific routines are introduced, spu_enumerate_spus(), spu_create_spu() and spu_destroy_spu(). The underlying design uses a new type, struct spu_management_ops, to hold function pointers that the platform setup code is expected to initialize to instances appropriate to that platform. For the IBM Cell Blade support, I put the hypervisor only resources that were in struct spu into a platform specific data structure struct spu_pdata.

2006-10-25[POWERPC] spufs: wrap mfc sdr accessMasato Noguchi
SPRN_SDR1 and the SPE's MFC SDR are hypervisor resources and are not accessible from a logical partition. This change adds an access wrapper. When running on bare H/W, the spufs needs to only set the SPE's MFC SDR to the value of the PPE's SPRN_SDR1 once at SPE initialization, so this change renames mfc_sdr_set() to mfc_sdr_setup() and moves the access of SPRN_SDR1 into the mmio wrapper. It also removes the now unneeded member mfc_sdr_RW from struct spu_priv1_collapsed.

2006-06-21[POWERPC] spufs: fix spu irq affinity settingGeoff Levand
This changes the hypervisor abstraction of setting cpu affinity to a higher level to avoid platform dependent interrupt controller routines. I replaced spu_priv1_ops:spu_int_route_set() with a new routine spu_priv1_ops:spu_cpu_affinity_set(). As a by-product, this change eliminated what looked like an existing bug in the set affinity code where spu_int_route_set() mistakenly called int_stat_get().

2006-06-21[POWERPC] spufs: further abstract priv1 register accessGeoff Levand
To support muti-platform binaries the spu hypervisor accessor routines must have runtime binding. I removed the existing statically linked routines in spu.h and spu_priv1_mmio.c and created new accessor routines in spu_priv1.h that operate indirectly through an ops struct spu_priv1_ops. spu_priv1_mmio.c contains the instance of the accessor routines for running on raw hardware.
