it actually do something on FullCPU. Still disabled, as it causes detailed-boot to hang when you turn it on. arch/alpha/isa_desc: Add EAComp and MemAcc pseudo-instructions to prefetch StaticInst. cpu/simple_cpu/simple_cpu.hh: Changed prefetch() return type from Fault to void. --HG-- extra : convert_revision : c7cb42682bfea6af117c87d4dfdb06176b6fe6b7

2004-02-24add in an init() callback for CPU's so that no stats are accessed prior to ↵Lisa Hsu
the end of the build process. (Done by doing the registerExecContext() calling sequence in the init() process rather than the create() process). cpu/simple_cpu/simple_cpu.cc: cpu/simple_cpu/simple_cpu.hh: same thing for simple cpu's. --HG-- extra : convert_revision : aac9f91742866fb26f8cace622f9b88454a69662

util/tracediff: Quote simulator args so args with spaces get handled correctly. --HG-- extra : convert_revision : b48677bc712be17e6e50ca35680e757ba9364692
2004-02-23Only one request may be on the dma interface at a time,Nathan Binkert
so add some states to indicate that the dma read/write hasn't issued yet, and add some support to reissue the request when the interface becomes unblocked. --HG-- extra : convert_revision : 448695a8eb2e9f98554769f3165df1f796adf44a

2004-02-21Change order of serializationNathan Binkert
sim/sim_object.cc: serialize objects in the reverse order of their creation. This causes a SimObject that is dependent on another to be serialized first. For example, the ethernet device writes back some data to physical memory while serializing, so this will cause the physical memory to be serialized after that, preserving the data written back. --HG-- extra : convert_revision : f9a37b63ce777df1cfecefa80f94f8fc69e42448

make it so that pio devices must respond with some delay. dev/io_device.cc: don't forget to include dma_interface.hh so we could use it. dev/io_device.hh: the generic BusInterface isn't enough for doing DMA we need the actual DMAInterface --HG-- extra : convert_revision : 70298d33c8520a3f4ad11aa600825a8cec7e44bf

In the future, this can be used for actual data, but for now, it's so that devices can respond to timing accesses properly.

Aligned copies now fully work in LRU (just need to write the IIC doCopy call).
