Scheduling group cleanup - add comment, SP_DEFAULT · 69bfb1f0

Glenn Kasten authored 13 years ago

Also tid == 0 maps to gettid() on platforms that support it.
This is needed by mediaserver code that was formerly using
the old C++ API.

More fixes to Binder perf regression from Eclair · e43c2483

Brad Fitzpatrick authored 15 years ago

Re-use the file descriptor to change the cgroups.  There's a fast path
in the kernel for the case where the value's already uncahnged.  Also,
this is okay because the kernel ignores the write offset.  This is
essentially a ioctl-ish/datagram interface, despite being a fd we're
writing to.

This reduces Dalvik->Dalvik void/void Binder calls on Sapphire from
~1.2 to ~0.8 ms.  This is a bit slower than the ~0.7 ms we get
avoiding the write altogether.

strace confirms:

[pid  1557] ioctl(21, 0xc0186201 <unfinished ...>
[pid  1556] <... ioctl resumed> , 0x45399cd0) = 0
[pid  1556] write(22, "1556", 4)        = 4
[pid  1556] ioctl(21, 0xc0186201 <unfinished ...>
[pid  1555] <... ioctl resumed> , 0x45299cd0) = 0
[pid  1555] write(22, "1555", 4)        = 4
[pid  1555] ioctl(21, 0xc0186201 <unfinished ...>
[pid  1554] <... ioctl resumed> , 0x45199cd0) = 0
[pid  1554] write(22, "1554", 4)        = 4

Optimize set_sched_policy(), which gets called in every binder call. · 253e27ac

Brad Fitzpatrick authored 15 years ago

- use static /dev/cpuctl filenames, rather than sprintf() on the fly
- use a custom formatter instead of sprintf() for the tid number

This is a simplified version of Dan's original
Ifc9c81f74fe65f0695ead53b30194bc6adf00da0 to be less risky for Froyo.
