- Subject: [PATCH] sharing spu _send_to_ppe()
The patch below modifies the definition of _send_to_ppe() in SPU
libgloss to make it possible to share it between libgloss and stdio
offloading routines.
Thanks,
2006-08-30 Kazunori Asayama <asayama@sm.sony.co.jp>
* spu/syscalls.c: Add a new argument to _send_to_ppe() to
specify signal code.
* spu/jsre.h: Update declaration of _send_to_ppe().
* spu/close.c: Replace _send_to_ppe_0x2101() by _send_to_ppe().
* spu/fstat.c: Ditto.
* spu/lseek.c: Ditto.
* spu/open.c: Ditto.
* spu/read.c: Ditto.
* spu/stat.c: Ditto.
* spu/unlink.c: Ditto.
* spu/write.c: Ditto.
