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.

2010-10-05broken 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]
2010-10-031. enable L2 cache as a texture cache (also some bug fixes for L2 as regular ↵Tor Aamodt
cache) 2. update gpgpusim.config for Quadro to use L1 cache geometry from Henry's ISPASS paper 3. minor edit to CUDA api : add notion of fat_cubin_handle (currently not used for anything) 4. minor edits to deadlock detection message (more accurate reporting of source of deadlock) 5. other minor edits [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7809]

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]

2010-08-23- add '-keep' option to keep intermediate files (used for OpenCL only right now)Tor Aamodt
- remove redundant initialization code of options (which confuses new users) - make bool option variables bool type - remove some more extern decls [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7247]

2010-07-21- reduce 3.1 sdk regression test runtimes (as per 2.3 sdk versions)Tor Aamodt
- add ldu support (just use ld for now) - get rid of asserts for .const[n] - status: cuda sdk 3.1 dct8x8, eigenvalues, MersenneTwister, reduction, scan still running (too slow) ocl sdk 3.1 oclQuasirandomGenerator still running (too slow) ocl sdk 3.1 oclReduction fail comparison (cuda 3.1) ocl sdk 3.1 oclMatrixMul exits mid computation ocl sdk 3.1 oclTranspose hits "clCreateBuffer - buffer already created for this host variable" ocl sdk 3.1 oclSortingNetworks fails w/ message about min workgroup size remaining 30 tests pass [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 6927]

2010-07-18- simple device printf support added (supports %u, %d, %f)Tor Aamodt
- add support to call_impl for passing values in through local param space (need to add support for return) - track local framesize during ptx parsing / update local stack-pointer during call/return - detect appropriate param space for ld.param (and st.param) depending upon address symbol's scope - putting back the crazy math for local mem allocation (seems to be required) - bug fix for global byte array initialization - force ld and st w/o space specifier to be generic_space - make type_decode method of type_info_key - adjust debug printing so listing of code and CFG information requires higher numbers (100 and 50) - local param ld/st accesses treated like local ld/st for timing model [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 6878]

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]
