This patch adds a command to xmon for dumping information about spu structs. The command is 'sf' for "spu fields" perhaps, and takes the spu number as an argument. This is the same value as the spu->number field, or the "phys-id" value of a context when it is bound to a physical spu. We try to catch memory errors as we dump each field, hopefully this will make the command reasonably robust, but YMMV. If people see a need we can easily add more fields to the dump in future. Output looks something like this: 0:mon> sf 0 Dumping spu fields at address c00000001ffd9e80: number = 0x0 name = spe devnode->full_name = /cpus/PowerPC,BE@0/spes/spe@0 nid = 0x0 local_store_phys = 0x20000000000 local_store = 0xd0000800801e0000 ls_size = 0x0 isrc = 0x4 node = 0x0 flags = 0x0 dar = 0x0 dsisr = 0x0 class_0_pending = 0 irqs[0] = 0x16 irqs[1] = 0x17 irqs[2] = 0x24 slb_replace = 0x0 pid = 0 prio = 0 mm = 0x0000000000000000 ctx = 0x0000000000000000 rq = 0x0000000000000000 timestamp = 0x0000000000000000 problem_phys = 0x20000040000 problem = 0xd000080080220000 problem->spu_runcntl_RW = 0x0 problem->spu_status_R = 0x0 problem->spu_npc_RW = 0x0 priv1 = 0xd000080080240000 priv1->mfc_sr1_RW = 0x33 priv2 = 0xd000080080250000 Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org> |
