* sky-pke.h (pke_fifo*): Exported these formerly private functions. (pke_device): Added FIFO cache fields. * sky-pke.c (pke_fifo_reset): New function for GPUIF client - clear FIFO contents. (pke_pcrel_fifo): Added caching facility to prevent O(n^2) cost for searching for consecutive operand words. * sky-libvpe.c (MEM, uMEM): New/changed macros that perform modulo calculations to handle out-of-range VU memory addresses. (*): Replaced many previous uses of MEM[] and state->uMEM[] with calls to above macros. * sky-vu.h (struct VectorUnitState): Added qw/dw size fields for MEM/uMEM buffers, for overflow prevention. Renamed MEM/uMEM fields to catch all their prior users. * sky-vu0.c (vu0_attach): Manually align MEM0/MEM1 buffers to force 16-byte alignment. (zalloc is not enough.) * sky-vu1.c (vu1_attach): Ditto. (init_vu): Store buffer sizes from allocation into VectorUnitState. * sky-gpuif.h (GifPath): Use a pke_fifo strucf instead of temporary fixed-size array for flexible FIFO sizing. * sky-gpuif.c (SKY_GPU2_REFRESH): This is now an integer value to be used as a modulus for periodic refresh. (refresh): New function to send GPU2 refresh code periodically. (*): Use pke_fifo calls to en/dequeue GPUIF tags & operands. * sky-pke.h (struct pke_device): Added fields to allow caching of results from recent FIFO searches.
