2010-10-081. refactoring cuda api code for loading PTX (removing external PTX loading ↵Tor Aamodt
entirely) 2. some bug fixes for warp_inst_t 3. creating a new class, gpgpu_t, which contains the functional "memory" state visible to all threads running on a GPU (doing this as part of my continuing effort to hunt down and eradicate every global variable that is not the top level "the gpu") 4. other misc. changes Almost passing CUDA 3.1 regression? oclHistogram keeps failing under torque, but does not fail when run on the command line from the same directory.

2010-10-05simulator "working" on ptxplus, simulated IPC "too low" by about a factor of ↵Tor Aamodt
up to 50% [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7816]
2010-10-05broken change list: builds, but does not run, yetTor Aamodt
refactoring: create warp_inst_t that provides notion of a group of scalar instructions traveling down the pipeline. delete DWF delete MIMD delete warp_tracker delete old writeback stage, replace it with a stub that just writes back everything delete old pipeline model current status: MSHR's need to change to deal with the new structure [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7814]
2010-10-03moving some CUDA API centric code to cuda_runtime_api.ccTor Aamodt

2010-10-01integrating recent changes from fermi-test into fermiTor Aamodt
(i'll use "fermi" for more disruptive changes to the pipeline model such as updating the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7805]
2010-08-29- integrate changes from fermi-test (CL's under that path in range 7261-7418).Tor Aamodt
(add scoreboard logic from ptxplus branch and modified operand collector with parallel ALU/SFU pipelines) passing regressions [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7419]
2010-08-08refactoring: start moving prototypes into headersTor Aamodt

2010-07-17param space updates for correct parsing (still need to allocate thread Tor Aamodt
local storage for local param memory) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 6871]
2010-07-17- adding new memory_space_t type to enable differentiation of differentTor Aamodt
parameter spaces (kernel parameters are conceptually different from function parameters, but PTX only has one .param keyword) - removing more dead code [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 6870]
2010-07-17- add support for cvta and isspacep instructions (currently assumingTor Aamodt
a fixed address mapping between shared,local to generic that depends upon hardware thread context used... might be interesting to explore tradeoffs at some point) - remove util.h... we don't need TRUE, FALSE anymore now that everything is C++ - remove some dead code from shader_decode [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 6867]
