| 2009-12-31 | MIPS: Implement the set_thread_area system call. | Gabe Black | |
| 2009-12-31 | MIPS: Create an artificial control register to hold the thread pointer. | Gabe Black | |
| In Linux, the set_thread_area system call stores the address of the thread local storage area into a field of the current thread_info structure. Later, to access that value, the program uses the rdhwr instruction to read a "hardware register" with index 29. The 64 bit MIPS manual, volume II, says that index 29 is reserved for a future ABI extension and should cause a "Reserved Instruction Exception". In Linux (and potentially other ISAs) that exception is trapped and emulated to return the value stored by set_thread_area as if that were actually stored by a physical register. The tp_value address (as named in the Linux kernel) is ironically stored as a control register so that it goes with a particular ThreadContext. Syscall emulation will use that to emulate storing to the OS's thread info structure, and rdhwr will emulate faulting and returning that value from software by returning the value itself, as if it was in hardware. In other words, we fake faking the register in SE mode. In an FS mode implementation it should work as specified in the manual. | |||
| 2009-12-31 | MIPS: Extract CPU pointer from the thread context in scheduleCP0 setMiscReg. | Gabe Black | |
| The MIPS ISA object expects to be constructed with a CPU pointer it uses to look at other thread contexts and allow them to be manipulated with control registers. Unfortunately, that differs from all the other ISA classes and would complicate their implementation. This change makes the event constructor use a CPU pointer pulled out of the thread context passed to setMiscReg instead. | |||
| 2009-12-21 | MIPS: Add missing syscall slots. | Gabe Black | |
| These are all after the existing ones, suggesting they were added after the original list was created. | |||

| 2009-11-18 | ruby: returns the number of LLC needed for broadcast | Brad Beckmann | |
| Added feature to CacheMemory to return the number of last level caches. This count is need for broadcast protocols such as MOESI_hammer. | |||
| 2009-11-18 | ruby: cache configuration fix to use bytes | Brad Beckmann | |
| Changed cache size to be in bytes instead of kb so that testers can use very small caches and increase the chance of writeback races. | |||

| Slightly improved the major hack need to correctly assign the number of ports per core. CPUs have two ports: icache + dcache. MemTester has one port. | |||
| 2009-11-18 | ruby: Added error check for openning the ruby config file | Brad Beckmann | |
| 2009-11-18 | ruby: Support for merging ALPHA_FS and ruby | Brad Beckmann | |
