2005-11-20Cleanup the StackTrace interfaces and profile interfaces so theyNathan Binkert
are more efficient and reduce the number of new/delete calls arch/alpha/stacktrace.cc: - Change the StackTrace code so that the class can more easily be cleaned out and reused to avoid extra allocations. - Allow trace() to accept a static instruction pointer so it can determine if the instruction is worth tracing. This is moved from the CPU. - provide constants for special meaning PCs (user, console, unknown), instead of magic numbers - switch to using kernelSymtab instead of allSymtab which will be going away - if the stack adjustment doesn't make any sense, exit and push unknown so we don't get into an infinite loop or record garbage. - check to see if we've made too many iterations through the stack and panic to avoid an infinite loop arch/alpha/stacktrace.hh: - Change the StackTrace code so that the class can more easily be cleaned out and reused to avoid extra allocations. - Allow trace() to accept a static instruction pointer so it can determine if the instruction is worth tracing. This is moved from the CPU. - provide constants for special meaning PCs (user, console, unknown), instead of magic numbers cpu/base.cc: only clear the profile if we have one include profile.hh here since base.hh doesn't do it anymore cpu/base.hh: no need to include cpu/profile.hh here cpu/profile.cc: use ProfileNode pointers instead of objects in the ChildList Consume a vector of addresses since that's really all we care about. cpu/profile.hh: Keep pointers to ProfileNodes to reduce the size of these structures keep a StackTrace around so that we may reuse it. provide consume functions that use the new StackTrace trace interface one consume function is inline and tries to fastpath the no trace condition, it calls the outlined consume function if a trace is generated. cpu/simple/cpu.cc: include cpu/profile.hh here since base.hh no longer does use the new FunctionProfile::consume interface (which contains the tracing functions) --HG-- extra : convert_revision : 5a1d9265289a75f67a497b322926be1f8c2d8eb3

2005-10-21Major changes to sinic device model. Rearrage read/write, betterNathan Binkert
interrupts. dev/sinic.cc: - The prepareRead function sets all the variables in the register file that depend on various state bits that change on the fly. Includes RxDone, RxWait, TxDone, and TxWait - Use the new register information accessor functions to grab validity and size information for the read and write functions - read all registers directly from the register space by offset and size, not by actual name (less code) - The side effect of reading the interrupt status (clearing it) now happens outside the actual chunk of code where the value is loaded. - Add an iprRead function for when we may want speculative access to device registers through an ipr or special instruction. - When RxData or TxData are written, their busy flag is set to indicate that they have an outstanding transaction. - The RxHigh and TxLow interrupts are special, they only interrupt if the rxEmpty or txFull limits were hit - Move reset to the command register - Update more registers on reset, clear rxEmpty and txFull - Data dumps only happen if EthernetData trace flag set - When a DMA completes, kick the other engine if it was waiting - implement all of the new interrupts - serialize the new stuff dev/sinic.hh: - Put all registers with their proper size and alignment into the regs struct so that we can copy multiple at a time. - Provide accessor functions for accessing the registers with different sizes. - Flags to track when the rx fifo hit empty and the tx fifo became full. These flags are used to determine what to do when below the watermarks, and are reset when crossing the watermark. - the txDmaEvent should actually trigger the txDmaDone function - Add an iprRead function for when we may want speculative access to device registers through an ipr or special instruction. - The prepareRead function sets all the variables in the register file that depend on various state bits that change on the fly. - add rx_max_intr and dedicated (for dedicated thread) config params dev/sinicreg.hh: Add some new registers: Command, RxMaxIntr, RxFifoSize, TxFifoSize, rename XxThreshold to XxFifoMark Move Reset to the Command register Add Thread to the Config register New interrupts, better names More info in RxDone and TxDone Easier access to information on each register (size, read, write, name) python/m5/objects/Ethernet.py: Both sinic and nsgige have the dedicated thread Add a parameter to configure the maximum number for receive packets per interrupt --HG-- extra : convert_revision : 407c5a993b6fb17326b4c623ee5d4b25fd69ac80
