[Pixman] [PATCH 4/8] MIPS: DSPr1: Basic infrastructure for DSPr1 optimizations
Nemanja Lukic

Mon Aug 19 07:16:52 PDT 2013
Some of the optimizations introduced in previous DSPr2 commits, similar to
previous patch, were not DSPr2 specific and utilized DSPr1 instructions only.
Since Pixman's run-time CPU detection only added DSPr2 fast-paths on 74K MIPS
cores, these optimizations couldn't be used on cores that don't support DSPr2,
but do support DSPr1 instructions (these are newer MIPS CPU cores like 24KE,
34K, 1004K, etc).
This patch extracts those DSPr1 specific optimizations into new dspr1 set of
fast-paths, and adds infrastructure for future DSPr1-only optimizations with
appropriate build and run time support.
Following is the list of DSPr1 optimizations, introduced in previous DSPr2
patches, tested on MIPS 1004Kc core:
Performance numbers before/after on MIPS-1004kc @ 800 MHz
Referent (before):
add_8888_8888 = L1: 26.48 L2: 19.70 M: 14.41 ( 42.67%) HT: 13.70 VT: 13.41 R: 12.97 RT: 9.84 ( 105Kops/s)
src_n_0565 = L1: 344.47 L2: 193.46 M:136.23 (100.70%) HT:115.48 VT:109.33 R:100.85 RT: 45.61 ( 253Kops/s)
Optimized (with these optimizations):
add_8888_8888 = L1: 226.21 L2: 64.57 M: 29.41 ( 86.96%) HT: 26.95 VT: 23.63 R: 23.66 RT: 15.25 ( 145Kops/s)
src_n_0565 = L1:-1041.15 L2: 695.23 M:444.03 (327.64%) HT:144.46 VT:130.94 R:121.60 RT: 43.95 ( 245Kops/s)
