| 2009-10-30 | Syscalls: Make system calls access arguments like a stack, not an array. | Gabe Black | |
| When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job. | |||

| 2009-07-10 | SPARC: Set up a lookup table for integer register flattening. | Gabe Black | |
| Using a look up table changed the run time of the SPARC_FS solaris boot regression from: real 14m45.951s user 13m57.528s sys 0m3.452s to: real 12m19.777s user 12m2.685s sys 0m2.420s | |||

| 2009-04-24 | SPARC: Tighten up the clone system call and SPARCs copyRegs. | Gabe Black | |
| 2009-04-21 | syscall: Resolve conflicts between m5threads and Gabe's recent SE changes. | Steve Reinhardt | |
| 2009-04-21 | Commit m5threads package. | Daniel Sanchez | |
| This patch adds limited multithreading support in syscall-emulation mode, by using the clone system call. The clone system call works for Alpha, SPARC and x86, and multithreaded applications run correctly in Alpha and SPARC. | |||
| 2009-04-19 | SE mode: Make keeping track of the number of syscalls less hacky. | Gabe Black | |
| 2009-04-15 | Get rid of the Unallocated thread context state. | Steve Reinhardt | |
| Basically merge it in with Halted. Also had to get rid of a few other functions that called ThreadContext::deallocate(), including: - InOrderCPU's setThreadRescheduleCondition. - ThreadContext::exit(). This function was there to avoid terminating simulation when one thread out of a multi-thread workload exits, but we need to find a better (non-cpu-centric) way. | |||
