Even if the writeback traffic is generated, the configuration (writeback cache + allocation-on-fill) will inevitably lead to deadlock. -- Added the ability plot stats with an increasing number of data points in aerielvision -- Added aerialvision support for profiling which warps issue on a sampling shader +- Added the ability plot stats with an increasing number of data points in aerielvision. + Developers can now add statistics for plotting where the number of entries in each slice is not known + initially. +- Added aerialvision support for profiling which warps issue on a sampling shader. + This is a cycle by cycle breakdown of what warpi_ids/dynamic_warp_ids the shader issued + on a given core over time plotted as a stacked bar chart. + For example, by default every 500 cycles you get a colored breakdown of what warps issued during those cycles. - Added DPRINTF support to gpgpusim.
