• b6ee75ed4   MIPS: Collect FPU emulator statistics per-CPU. ... Browse Code »

  On SMP systems, the collection of statistics can cause cache line
  bouncing in the lines associated with the counters. Also there are
  races incrementing the counters on multiple CPUs.

  To fix both problems, we collect the statistics in per-CPU variables,
  and add them up in the debugfs read operation.

  As a test I ran the LTP float_bessel test on a 12 CPU Octeon system.

  Without CONFIG_DEBUG_FS : 2602 seconds.
  With CONFIG_DEBUG_FS: 2640 seconds.
  With non-cpu-local atomic statistics: 14569 seconds.

• ba3049ed4   MIPS: Switch FPU emulator trap to BREAK instruction. ... Browse Code »

  Arguably using the address error handler has always been ugly. But with
  processors that handle unaligned loads and stores in hardware the
  current mechanism ceases to work so switch it to a BREAK instruction and
  allocate break code 514 to the FPU emulator.

  Yoichi Yuasa provided a build fix for CONFIG_BUG=n.

  Initial git repository build. I'm not bothering with the full history,
  even though we have it. We can create a separate "historical" git
  archive of that later if we want to, and in the meantime it's about
  3.2GB when imported into git - space that would just make the early
  git days unnecessarily complicated, when we don't have a lot of good
  infrastructure for it.

  Let it rip!
